In this case, the spectacle device 1 200-1 opens both the left shutter glass and the right shutter glass when one content A is displayed according to the synchronization signal, and the left shutter when the other content B is displayed. It may be operable to turn off both the glass and the right shutter glass. Accordingly, viewer 1 wearing eyeglass device 1 200-1 synchronizes one content (synchronized with eyeglass device 1 200-1) among a plurality of contents A and B that are alternately displayed. A) You can watch only. In the same manner, viewer 2 wearing the spectacles 2 200-2 may watch the content B only. The alternating display of image frames for different content is achieved at a very high speed, and the afterimage effect of the retina persists while the lens is closed, making the image appear natural to the user.

2 is a view for explaining a method of providing a plurality of 3D content according to an embodiment of the present invention.

As shown in the drawing, when the plurality of 3D contents (contents A and B) are 3D contents, the display apparatus 100 alternately displays the plurality of 3D contents (contents A and B), while the left eye image of each 3D content and The right eye image can also be displayed alternately.

For example, the left eye image and the right eye images AL and AR of the 3D content A may be displayed, and the left eye image and the right eye images BL and BR of the 3D content B may be alternately displayed. In this case, the eyeglass device 1 200-1 opens the left eye and the right eye glass at the display time point of the left eye image and the right eye image AL and AR of the 3D content A, and the eyeglass device 2 200-2 the 3D content B. The left eye and right eye glasses may be opened at the display time point of the left eye image and the right eye image BL and BR.

Accordingly, viewer 1 wearing the eyeglass device 1 200-1 views only the 3D content A, and viewer 2 wearing the eyeglass device 2 200-2 views the 3D content B only. You will watch.

However, this is a description of a case in which the shutter glass method is assumed, and in the case of the polarization method, the polarization direction of each of the plurality of content images and the polarization directions of the spectacles 1 and 2 may be implemented to support the multi-view mode. It will be apparent to those skilled in the art.

According to FIG. 3, the display apparatus 100 may broadcast or multicast a single signal muxed with a synchronization signal corresponding to the spectacle apparatus 1 200-1 and the spectacle apparatus 2 200-2. The spectacle apparatuses 200-1 and 200-2 may operate to turn on / off the shutter glass in synchronization with a synchronization signal corresponding to a user command (eg, a channel switching command) among the corresponding signals.

However, the above-described embodiment is merely an example, and as shown in FIG. 4, the display apparatus 100 may provide a synchronization signal corresponding to the eyeglass apparatus 1 200-1 and the eyeglass apparatus 2 200-2. Each of the corresponding glasses apparatuses 200-1 and 200-2 may be unicasted, and the glasses apparatuses 200-1 and 200-2 may receive a corresponding synchronization signal.

Meanwhile, the synchronization signal may be implemented in the form of an RF (Radio Fequency) signal or an Infra Red (IR) signal, which will be described later.

5 is a block diagram illustrating a configuration of a display apparatus according to various embodiments of the present disclosure.

Referring to FIG. 5, the display apparatus 100 includes a plurality of receivers 110-1, 110-2,..., 110-n, and a plurality of signal processors 120-1, 120-2,. n), an output unit 130, a synchronization signal generator 140, an interface unit 150, and a controller 160.

The plurality of receivers 110-1, 110-2,..., 110-n receive different contents, respectively. In detail, each receiver 110-1, 110-2,..., 110-n stores contents from a broadcasting station transmitting broadcast program content using a broadcast network or a web server transmitting content files using the Internet. Receive. It is also possible to receive content from various recording medium playback apparatuses provided in the display apparatus 100 or connected to the display apparatus 100. [ The recording medium playback device refers to a device that plays back content stored in various types of recording media such as CD, DVD, hard disk, Blu-ray disk, memory card, USB memory,

In an embodiment of receiving content from a broadcasting station, the plurality of receivers 110-1, 110-2,..., 110-n may include a tuner (not shown), a demodulator (not shown), and an equalizer (not shown). It may be implemented in a form including a configuration such as. In contrast, in an embodiment of receiving content from a source such as a web server, the plurality of receivers 110-1, 110-2,..., 110-n may be implemented as a network interface card (not shown). . Alternatively, in the case of receiving the contents from the various recording medium reproducing apparatuses described above, the plurality of receiving units 110-1, 110-2,..., 110-n may include an interface unit (not shown) connected to the recording medium reproducing apparatus. May be implemented. For example, an AV terminal, a COMP terminal, and an HDMI terminal.

As such, the plurality of receivers 110-1, 110-2,..., 110-n may be implemented in various forms according to embodiments.

In addition, the plurality of receivers 110-1, 110-2,..., 110-n may not necessarily receive content from the same type of source, but may also receive content from different types of sources.

The plurality of signal processing units 130-1, 130-2,..., And 130-n respectively receive content received from the plurality of receivers 110-1, 110-2,..., 110-n. Various signal processing can be performed.

In particular, the plurality of signal processing units 130-1, 130-2,..., 130-n process each received image in the form of an image frame, and perform luminance adjustment processing for each of the plurality of contents processed in the form of a frame. Can be done.

Meanwhile, according to various embodiments of the present disclosure, the display apparatus 100 may further include a mux unit (not shown) for multiplexing image frames. The MUX unit 170 may multiplex and output the image frames such that the image frame of the first content, the image frame of the second content, ..., and the image frame of the n-th content are alternately arranged one by one.

The output unit 130 displays a plurality of contents according to data output from the mux unit (not shown). Accordingly, the output unit 130 may be displayed in a form in which at least one image frame of each content is alternately arranged.

The output unit 130 outputs one content view in the single view mode (first mode) and combines and outputs a plurality of content views in the multi view mode (second mode).

The output unit 130 may include a liquid crystal display panel, a plasma display panel, organic light emitting diodes (OLED), a vacuum fluorescence display (VFD), a field emission display (FED), and an ELD ( Electro Luminescence Display) and the like.

As described above, a mode for alternately arranging and displaying image frames of each content may be referred to as a multi view mode (or a second mode or a dual view mode). When the display apparatus 100 operates in a normal mode (or a single view mode (first mode)) displaying only one 2D content or 3D content, the plurality of receivers 110-1, 110-2,..., 110 Only one of -n) can be activated to process content. When the user selects the multi-view mode (second mode) while operating in the normal mode, the display apparatus 100 may process the data in the above-described manner by activating the remaining receiver.

Meanwhile, the above-described content may be 2D content or 3D content. 3D content refers to content that allows a user to feel three-dimensional by using a multi-view image in which the same object is expressed from different perspectives.

In the case of using a plurality of 3D contents, the output unit 130 may include a left eye image and a right eye included in each 3D content provided by the plurality of frame rate converters 122-1, 122-2, ..., 122-n. Images may be multiplexed in a predetermined arrangement and alternately arranged with image frames of other contents.

Accordingly, the left eye image, the right eye image of the first content, the left eye image of the second content, the right eye image, the left eye image of the n-th content, and the right eye image are sequentially arranged and displayed, and the user displays the eyeglasses 200. Through this, the left eye image and the right eye image of one content are recognized.

Meanwhile, the display apparatus 100 further includes a configuration for differently providing audio data included in each content for each user when operating in the multi-view mode (second mode). That is, a demultiplexer (not shown) for separating video data and audio data from content received at each receiver 110-1, 110-2,..., 110-n, and an audio decoder for decoding the separated audio data. (Not shown), a modulator (not shown) for modulating the decoded audio data into different frequency signals, an output unit (not shown) for transmitting the modulated audio data to the spectacle device, and the like. The audio data output from the output unit 130 is provided to the user through an output means such as an earphone provided in the spectacle device. Since these configurations are not directly related to the present invention, a separate illustration is omitted.

In some cases, if the content includes additional information such as an EPG (Electronic Program Guide) and subtitles, the demultiplexer may further separate the additional data from the content. In addition, the display apparatus 100 may add a subtitle or the like processed to be displayed through an additional data processor (not shown) to the corresponding image frame.

The synchronization signal generator 140 generates a synchronization signal for synchronizing the glasses device corresponding to each content according to the display timing of each content. That is, the synchronization signal generator 140 generates a synchronization signal for synchronizing the spectacles with the display timing of the image frame for the content in the multi-view mode (second mode).

The interface unit 150 transmits a synchronization signal to the spectacles. In this case, the interface unit 150 may transmit the synchronization signal to the spectacles device in various ways.

For example, the interface unit 150 may include an RF communication module to communicate with the spectacles. Herein, the RF communication module may be implemented as a Bluetooth communication module. Accordingly, the interface unit 150 may generate a transmission stream according to the Bluetooth communication standard so as to include a synchronization signal and transmit the generated stream to the spectacles.

That is, the transport stream includes time information for turning on / off the shutter glass of the spectacle device in synchronization with the display timing of each content. Specifically, the transport stream includes an offset time for turning on the left eye shutter glass of the spectacle apparatus, an offset time for turning off the left eye shutter glass, an offset time for turning on the right eye shutter glass, and a right eye shutter glass from a reference time point set for each content. It may include information about the offset time to turn off. Here, the reference time point is a time point at which the vertical sync signal is generated in the image frame of each content, and time information on the time point at which the vertical sync signal is generated may also be included in the transport stream.

In order to perform communication according to the Bluetooth communication method, the interface unit 150 performs pairing with each eyeglass device. When pairing is completed, information about each eyeglass device, for example, a device ID (or address), may be registered in the interface unit 150. The interface unit 150 matches a display timing of each content with information about the glasses device and generates one transport stream according to the Bluetooth communication standard. For example, the interface unit 150 may match information about different glasses devices for each content in the order in which the image frames of the content are arranged. That is, when two contents are alternately provided in the multi-view mode (second mode), the image frames of the contents arranged in the first, third, ..., n-th are used to provide information about the first glasses device. The image frames of the contents arranged in the second, fourth,..., N + 1 th may match information about the second spectacle device (where n is odd). The eyeglasses may check the display timing corresponding to the eyeglass apparatus information when the synchronization signal is received, and turn the shutter glass on or off according to the confirmed display timing.

Although the above-described embodiment has been described as the interface unit 150 and the spectacle device performing communication according to the Bluetooth communication method, this is only an example. That is, in addition to the Bluetooth method, it is possible to use a communication method such as infrared communication, Zigbee, etc., and to perform communication according to various wireless communication methods capable of transmitting and receiving signals by forming a communication channel in other local areas. .

The interface unit 150 may provide an IR (Infra Red) synchronization signal having a different frequency to the spectacle device. In this case, the spectacle apparatus may receive a synchronization signal having a specific frequency and turn on or off the shutter glass according to the display timing of the corresponding content.

In this case, the interface unit 150 glasses the infrared signal in which the high level during the first period and the low level during the second period are alternately repeated at predetermined time intervals based on the synchronization information. Can be sent to the device. The spectacle device may be implemented to turn on the shutter glass during the first period at the high level and to turn off the shutter glass during the second period at the low level. In addition, the synchronization signal may be generated in various ways.

The controller 160 controls operations of the first half of the display apparatus 100. Specifically, the controller 160 includes a plurality of receivers 110-1, 110-2,..., 110-n, and a plurality of signal processors 130-1, 130-2,..., 130-n. Each control unit may be controlled to perform a corresponding operation by controlling each of the MUX unit (not shown), the output unit 130, the synchronization signal generator 140, and the interface unit 150. On the other hand, since the operation performed by each configuration of the display apparatus 100 has been described above, duplicate description thereof will be omitted.

6 is a block diagram showing the configuration of the signal processor 130.

Referring to FIG. 6, the arbitrary signal processor 120-1 may include a video processor 121-1 and a frame rate converter 122-1.

The video processor 121-1 performs signal processing on video data included in the received content. In detail, the video processor 121-1 may include a decoder (not shown) that performs decoding on video data, and a scaler (not shown) that performs up or down scaling in accordance with the screen size of the output unit 130. Can be.

In addition, the video processor 121-1 may convert the video data into a data format corresponding to the frame rate converter 122-1. For example, image frames of respective contents may be connected in a horizontal direction to be converted into a side-by-side format.

The frame rate converter 122-1 converts the frame rate of the content provided from the video processor 121-1 to match the multi-content display rate with reference to the output rate of the display apparatus 100. In detail, when the display apparatus 100 operates at 60 Hz, the frame rate converter 122-1 may convert the frame rate of each content to n × 60 Hz.

7 is a block diagram illustrating a configuration of an eyeglass device 200 according to various embodiments of the present disclosure.

Referring to FIG. 7, the spectacle apparatus 200 is interlocked with a display apparatus 100 that alternately displays a plurality of contents in image frame units, and includes a communication interface 210, a controller 220, and a shutter glass driver ( 230, a first shutter glass unit 250, and a second shutter glass unit 260.

The communication interface 210 receives a synchronization signal from the display device.

For example, when the communication interface 210 is implemented as a Bluetooth communication module, communication with the display apparatus 100 according to a Bluetooth communication standard may be performed to receive a transport stream including a synchronization signal. In this case, the transport stream includes time information for turning on or off the first shutter glass unit 250 and the second shutter glass unit 260 of the spectacles 200 in synchronization with the display timing of each content. The apparatus 200 may turn on or off the shutter glasses according to the display timing corresponding to the glasses device.

Unlike this, the communication interface 210 may be implemented as an IR receiving module to receive an infrared signal having a specific frequency. In this case, time information for turning on or off the first shutter glass unit 250 and the second shutter glass unit 260 of the spectacles 200 to be synchronized with the display timing of one of the plurality of contents is included. do.

Meanwhile, the communication interface 210 may receive information about an image frame rate and an image frame period for each content from the display apparatus 100.

The controller 220 controls the operation of the first half of the spectacles 200. In particular, the controller 220 transmits the synchronization signal received from the interface unit 210 to the shutter glass driver 230 to control the operation of the shutter glass driver 230. That is, the controller 220 controls the shutter glass driver 230 to generate driving signals for driving the first shutter glass unit 250 and the second shutter glass unit 260 based on the synchronization signal.

The shutter glass driver 230 generates a driving signal based on the synchronization signal received from the controller 220. In particular, the shutter glass driver 230 may include the first shutter glass unit 250 and the second shutter glass unit based on a display timing of one of a plurality of contents displayed on the display apparatus 100 based on the synchronization signal. 260 may be opened.

The first shutter glass unit 250 and the second shutter glass unit 260 turn on or off the shutter glass according to a driving signal received from the shutter glass driver 230. Specifically, the first shutter glass unit 250 and the second shutter glass unit 260 simultaneously open the shutter glass when one of the plurality of contents is displayed, and turn off all of the shutter glasses when the other contents are displayed. Let's do it. Accordingly, a user wearing the spectacles 200 may view one content.

In the case of 3D content, the first shutter glass unit 250 and the second shutter glass unit 260 may alternately open and close the respective glasses. That is, the first shutter glass unit 250 may be opened at the timing when the left eye image constituting one 3D content is displayed according to the driving signal, and the second shutter glass unit 260 may be opened at the timing when the right eye image is displayed. Can be.

Based on user fluctuations contents  View The content view mode  Embodiment to switch

Hereinafter, a system and method for switching the view mode according to a change state of a user viewing the display apparatus 100 according to various embodiments of the present disclosure will be described.

8 is a block diagram showing a configuration of a display apparatus 100 according to this embodiment of the present invention.

Referring to FIG. 8, the display apparatus 100 according to the present invention includes a receiver 110, a signal processor 120, a mux unit, an output unit 130, a controller 160, an interface unit 150, and a synchronization signal generator ( 140, an imaging unit 170, and a storage unit 180.

Since the receiver 110, the signal processor 120, the mux unit, the output unit 130, the controller 160, the interface unit 150, and the synchronization signal generator 140 have been described above, redundant descriptions will be omitted. Functions of the imaging unit 120, the storage unit 180, and the control unit 160 according to the present embodiment will be described.

The imaging unit 120 functions to perform imaging.

Here, the imaging unit 120 may be implemented as a general camera, but in some cases, may be implemented in a form including at least one of a depth camera and a color camera. Here, the depth camera may recognize the distance to the user, the remote controller, and the like, the user motion, and the color camera may recognize the user's face, the hand motion, and the like. Meanwhile, the depth camera may be implemented to correct the captured image according to the depth, that is, the distance from the camera, and the correction form may be a form of enlargement / reduction of the screen, adjustment of resolution, and the like.

Meanwhile, in the illustrated embodiment, the image capturing unit 120 has been described as being a built-in camera provided in the display apparatus 100. However, this is only an example, and the image capturing apparatus 10 may be configured as the display apparatus 100. It may also be implemented as an external camera provided separately.

However, hereinafter, it will be assumed that the imaging device 10 is provided separately from the display apparatus 100 for convenience of description.

In this case, the controller 160 detects a fluctuation state of the user viewing the display apparatus 100 using the data captured by the image capturing unit 170, and according to the fluctuation state of the user, the single view mode (first mode) or the multi view. The output unit 130 may be controlled to operate in a mode (second mode).

In detail, the controller 160 may analyze the data captured by the imaging unit 170 to detect whether the user is separated from the space to be photographed or added, whether the added user was a previously separated user, or the like.

Accordingly, the controller 160 may control the output unit 130 to switch to the multi-view mode (second mode) when a user addition is detected while the output unit 130 operates in the single view mode (first mode). Can be.

In addition, the controller 160 may control the output unit 120 to switch to the single view mode (first mode) when the user departure is detected while the output unit 130 operates in the multi view mode (second mode). Can be.

The storage unit 180 is a storage medium that stores various programs required for operating the display apparatus 100, and may be implemented as a memory, a hard disk drive (HDD), or the like. For example, the storage unit 180 may store a program for performing an operation of the controller 160, may temporarily store data according to an operation of the controller 180, or store various reference data.

The controller 160 controls the output unit 130 to switch to the single view mode (first mode) when the user departure is detected while the output unit 130 operates in the multi-view mode (second mode). At the same time, the corresponding content view environment information may be stored in the storage unit 180.

In addition, when the separated user returns, the controller 160 reconfigures the content view corresponding to the separated user by using viewing environment information of the content view stored in the storage unit 180, and includes a plurality of reconstructed content views. The output unit 130 may be controlled to output the content view. In this case, the controller 160 may determine whether the previous user returns by detecting whether the newly added user is a previously separated user through the image captured by the imaging unit 170.

Meanwhile, face recognition technology may be applied to the captured image to detect whether the separated user returns. Face recognition technology is a technology that establishes a database of existing face photographs and checks and recognizes whether or not it is the same as an existing uncovered photograph based on the image captured by the camera. Face recognition technology can be basically achieved through a two-step process of face detection, face recognition. For face detection, knowledge-based methods, feature-based methods, template-matching methods, etc. may be used. For face recognition, 2D algorithms, 3D Algorithms and the like can be used. Since the face recognition technology is well known in the art, a detailed description thereof will be omitted.

Meanwhile, the viewing environment information of the content view includes content type (or channel number), volume, screen mode, backlight, brightness, sharpness, black tone, contrast, Information such as color, tint, position and size of the subtitle may be included.

However, the environment information when the content is a 2D image and the environment information when a 3D image may include a somewhat different configuration. For example, the environment information in the case of a 2D image may include backlight, brightness, sharpness, contrast, color, tint, and 3D image. The environment information in the case may further include a depth, a viewpoint, and the like. In addition, the environment information may include equalizer information (balance, amplification level for each frequency band), SRS TruSurround HD, volume information, and the like.

The storage unit 180 may store the viewing environment information of the content view set individually for each user.

In this case, when detecting the addition of a new user through the image captured by the imaging unit 170, the controller 160 uses the viewing environment information of the content view corresponding to the new user among the viewing environment information stored in the storage unit 180. By configuring a new content view, the output unit 130 may be controlled to output a plurality of content views including the new content view.

In addition, the controller 160 may set the display mode to the public mode or the private mode according to a user command transmitted from the spectacle device (not shown). However, the present invention is not limited thereto, and the user command may be transmitted from a remote control device such as a remote controller.

In detail, when the public mode is set, the controller 160 may switch between the multi-view mode (second mode) and the single-view mode (first mode) according to a user change state. That is, in the public mode, the content view can be freely changed.

In addition, when the private mode is set, the controller 160 prohibits switching between the multi-view mode (second mode) and the single-view mode (first mode) even when a user change state is detected. In the second mode). For example, in the private mode, even though the user addition is detected in the single view mode (first mode), the added user may not be able to view the corresponding content by maintaining the single view mode (first mode).

Meanwhile, the above-described private mode and public mode have been described in association with a multi-view mode (second mode) and a single view mode (first mode) according to a user change state, and according to another embodiment of the present invention, private mode and public mode The mode may be operated separately from the multi view mode (second mode) and the single view mode (first mode) according to the user change state.

In this case, in the private mode, when the specific content view is set to the private mode, even if the spectacle device (not shown) of another viewer is connected to the display device 100, the content view is set to the spectacle device (not shown) in private mode. It can be implemented to block the synchronization signal for. Detailed description thereof will be described later with reference to the accompanying drawings.

On the other hand, the imaging unit 170 may image the IR signal output from the remote control device (not shown).

In this case, when a user command is received from a remote controller (not shown) in a state of operating in a multi-view mode (second mode), the control unit 160 receives a captured image of an IR signal captured by the imaging unit 170. By detecting an adjacent user from a remote control device (not shown), the received user command may be applied to a content view corresponding to the detected user.

For example, in the case where only one remote controller is used in the multi-view state, assuming that a command for synchronizing content to the remote controller itself is not input, the corresponding remote controller signal is displayed by any one of a plurality of users on the display apparatus 100. It may be a scenario of detecting whether the user command is applied and applying the user command to the corresponding content view. In this case, a method of detecting a user who inputs a user command by analyzing a remote controller (not shown) and an image captured by the user may be possible.

Meanwhile, in the above-described embodiment, the case in which the private mode is set through the spectacle device (not shown) has been described. However, the present invention is not limited thereto, and the private mode may be preset for each type of content. For example, a broadcast program screen of a parental level, a game screen of various game programs, a message screen of a messenger program, a mail check screen, or a social network service screen, in which minors are prohibited from watching, are preset in a private mode. There may be. As such, information on the type of content set in the private mode may be pre-registered in a memory (not shown) in the display apparatus 100 or provided from a separate external source.

In addition, when the new user is added to the multi-view mode (second mode) in the single view state, the controller 160 synchronizes different content views to the left eye glasses and the right eye glasses of the eyeglass apparatus (not shown) of the new user. The new user can select the desired content view.

In addition, the controller 160 may detect a user's motion from the image captured by the imager 170 and control a plurality of content views according to the detected user's motion.

For example, the controller 160 may detect the user's left or right hand through the captured image and control different content views according to the control operation of the left or right hand. For example, the first content view may be controlled when the control operation of the left hand is detected, and the second content view may be controlled when the control operation of the right hand is detected.

In addition, when the viewer of the content view moves his hand horizontally from left to right (or right to left), the controller 160 may switch content, and in this case, a method of recognizing a hand shape may be applicable.

Hereinafter, the eyeglass apparatus 200 according to the exemplary embodiment of switching the view mode according to the change state of the user will be described.

For example, the input unit 240 may be implemented as at least one of a touch sensor, an operation button, and a slide switch.

In this case, when the content view switch command is input, the controller 220 sequentially turns on / off the first shutter glass unit 250 and the second shutter glass unit 260 according to the synchronization signal received from the display apparatus 100. The shutter glass driver 230 may be controlled to control the shutter glass driver 230.

In addition, when the private mode or the public mode is selected, the controller 220 may control to transmit a user command according to the corresponding mode to the display apparatus 100. In this case, the transport stream may include information on a private mode or a public mode according to a user command. In addition, the transport stream may include information on the 3D mode or the dual view mode according to the user command.

FIG. 10 is a view for explaining an external configuration of the spectacle apparatus 200 according to an embodiment of the present invention shown in FIG. 9.

As illustrated in FIG. 10, the spectacle apparatus 200 according to an exemplary embodiment may include a plurality of input buttons 241, 242, and 243.

Each of the plurality of input buttons 241, 242, and 243 may receive different user commands.

For example, each of the plurality of input buttons 241, 242, and 243 inputs a pairing command for performing pairing with the display autonomous 100, 300, a content view switching command, a mode setting command for setting a private or public mode, and the like. I can receive it.

However, the above-described input button is only an embodiment, and may be implemented in the form of a touch sensor or a slide switch, and in some cases, may be provided in the form of a menu through the display apparatuses 100 and 300. Do.

Hereinafter, a method of implementing a private mode and a public mode according to an embodiment of the present invention.

11 and 12 are diagrams for describing a private mode and a public mode implementation method according to an embodiment of the present invention.

As shown in FIG. 11, when the content is set to the public mode, the corresponding content can be viewed by other users (viewer 2). That is, the synchronization signal of the corresponding content may be transmitted to the glasses device 200-2 worn by the viewer 2 as well as the glasses device 200-1 worn by the viewer 1.

However, as shown in FIG. 12, when the private mode is set for a specific content, other users (viewer 2) cannot view the corresponding content, and the other user (viewer 2) has a UI for selecting a default channel or a new channel. Can provide. That is, the synchronization signal of the corresponding content may be implemented to be blocked by the glasses device 200-2 worn by another user (viewer 2).

13 and 14 are diagrams illustrating an example of a user interface screen associated with mode setting illustrated in FIGS. 11 and 12.

When the mode setting command is input through the spectacle apparatus 200-1 of the user viewing the specific content, the mode is displayed on the screen (display unit) of the display apparatus 100 as illustrated in FIGS. 13 and 14. A UI screen for confirming the change may be displayed. However, this is only an example, and may be implemented so that a mode change is performed immediately according to a mode setting command input without displaying a corresponding UI.

15 and 16 are diagrams for describing a method of using a captured image, according to another exemplary embodiment.

As shown in FIG. 15, when a plurality of users (viewer 1 and viewer 2) use one remote control device 300 in a multi-view mode (second mode), the image captured by the camera 10 is used. It may be detected by which user the remote control signal transmitted from the remote control device 300 is transmitted.

Alternatively, an IR signal output from the remote control apparatus 300 may be sensed through an image captured by the camera 10 to detect which user the corresponding remote control signal is transmitted. In this case, even when using the RF communication, the remote control apparatus 300 may be implemented to transmit some remote control signals such as device ID signals through IR signals.

As shown in FIG. 16, even when a plurality of users use separate remote control devices 300-1 and 300-2 in the multi-view mode (second mode), the remote control devices 300-1 and 300-are used. Unless 2) is paired to a specific content, it is not possible to know which user the transmitted remote control signal is transmitted by. Thus, the same method as in FIG. 15 may detect which user the remote control signal is transmitted by.

17 is a view for explaining a multi-view switching method according to another embodiment of the present invention.

As illustrated in FIG. 17, when a new user is added in the single view mode (first mode), at least two possible content views may be provided to the new user while being switched to the multi view mode (second mode). Accordingly, the new user can select the desired content. For example, different content views are provided to the left eye glass and the right eye glass of the new user, and the new user can select the desired content view.

18 is a flowchart illustrating a display method according to an exemplary embodiment.

According to the display method of the display apparatus illustrated in FIG. 18, one content view is output in the single view mode (first mode) and a plurality of content views are combined and output in the multi view mode (second mode). To perform the butterfly (S1810).

In operation S1820, a change state of a user who views the display apparatus is detected using the data captured in operation S1810.

Thereafter, the device operates in the single view mode (first mode) or the multi view mode (second mode) according to the user variation detected in operation S1810 (S1830).

In this case, in operation S1830 operating in the single view mode (first mode) or the multi view mode (second mode), when the user addition is detected while operating in the single view mode (first mode), the multi view mode (the first mode) may be used. 2 mode), and when the user departure is detected while operating in the multi-view mode (second mode), it may be switched to the single view mode (first mode).

In addition, when a user departure is detected while operating in the multi-view mode, the user switches to the single-view mode (first mode) and corresponds to the user who has exited from the plurality of content views output in the multi-view mode (second mode). The viewing environment information of the content view may be stored.

In addition, when the detached user returns, the content view corresponding to the detached user may be reconfigured using the viewing environment information of the content view, and a plurality of content views including the reconstructed content view may be output.

On the other hand, when the public mode is set, switching between the multi view mode (second mode) and the single view mode (first mode) is performed according to the user change state, and when the private mode is set, even if the user change state is detected Switching between the multi-view mode (second mode) and the single-view mode (first mode) is prohibited and can be fixedly operated in the multi-view mode (second mode).

In addition, the display device may pre-store viewing environment information of the content view individually for each user.

In this case, in operation S1830 operating in the single view mode (first mode) or the multi view mode (second mode), when a new user addition is detected, new content is generated using the viewing environment information of the content view corresponding to the new user. A view may be constructed and a plurality of content views including the new content view may be output.

In addition, when a user command is received from the remote controller while the IR signal is output from the remote controller and is operated in the multi-view mode (second mode), a user adjacent to the remote controller may be captured through the captured image of the IR signal. Can be detected. Subsequently, the user command may be applied to the content view corresponding to the detected user.

Since these embodiments have been described above, overlapping description and illustration are omitted.

Meanwhile, the program for performing the method according to various embodiments of the present disclosure described above may be stored and used in various types of recording media.

Specifically, the code for performing the above-described methods may be stored in a storage medium such as a RAM (Random Access Memory), a FLASH memory, a ROM (Read Only Memory), an EPROM (Erasable Programmable ROM), an EEPROM (Electronically Erasable and Programmable ROM) Such as a floppy disk, a removable disk, a memory card, a USB memory, a CD-ROM, and the like.

Embodiment of performing a video call through the display apparatus 100

Hereinafter, when the display apparatus 100 outputs a plurality of contents, a system and method for replacing a video frame of one of the contents with a video call screen will be described.

19 is a conceptual diagram illustrating a system for providing a video call function while providing content through the display apparatus 100 according to the present invention.

19 illustrates a case where a video call for one content is replaced with a video call screen to perform a video call. Hereinafter, the display apparatus 100 and the spectacle apparatus 200 of the present invention will be described in detail with reference to the exemplary embodiment of FIG. 19.

 20 is a block diagram illustrating a configuration of a display apparatus 100 according to various embodiments of the present disclosure, and FIG. 21 is a flowchart illustrating a video call method using the display apparatus 100 of FIG. 3.

20 to 21, the display apparatus 100 according to various embodiments of the present disclosure may include a receiver 110, a signal processor 120, an outputter 130, an interface unit 150, and a synchronization signal generator. 140, a video call processor 190, and a controller 160.

Since the receiver 110, the signal processor 120, the output unit 130, the interface unit 150, and the synchronization signal generator 140 have been described above, the video call processor 190 and the controller 160 are additionally described here. Explain.

FIG. 22 is a block diagram of a display apparatus 100 showing a specific configuration of an interface unit 150 and a video call processor 190 according to various embodiments of the present disclosure, and FIG. 23 is a display apparatus 100 of FIG. 22. 24 is a flowchart illustrating a process of performing a video call using the above, FIG. 24 is a conceptual diagram illustrating that a video frame of content is replaced with a video frame for a video call screen, and FIG. 25 displays a message inquiring whether to perform a video call. A flowchart illustrating a process of performing a video call including the steps of: performing a video call.

22 and 23, the video call processing unit 190 receives a video call request and connects a video call. A video call refers to a call method while viewing a counterpart through a display. The video call is classified into a circuit switching method using a switch and a packet switching method. In the latter case, voice can be transmitted through an IP (Internet Protocol) network using VoIP technology. It can be implemented using various other protocols.

The video call processing unit 190 includes an interface unit 190 for receiving a video call connection command, an image capturing unit 191 for capturing an image, a video call receiving unit 192 for receiving video call data, and video data and image capturing. It may include a call screen processing unit 193 for configuring a video call screen using the data.

The interface unit 150 receives a video call connection command. When the video call receiving unit 192 described later first receives a video call request, the interface unit 150 receives a video call connection command from one of the plurality of eyeglasses 200 corresponding to the plurality of contents. In this case, the controller 160 controls the video call processor 190 to connect a video call with a corresponding node that has transmitted a video call request. The interface unit 150 may be implemented by any kind of technical means capable of inputting a call connection command to the display apparatus 100 such as a button or a touch screen. In addition, the display apparatus 100 may be located on all surfaces related to the display apparatus 100, such as the surface of the display apparatus 100, the spectacle apparatus 200 to be described later, or a remote controller (not shown). For example, the spectacles 200 may be provided with a video call connect / end button (see 240 ′ in FIG. 26) to connect or end the video call to the spectacle frame portion. In this case, when the user receives a video call (that is, when a video call request is received from the display device), the user presses the video call connect / end button (see 240 ′ in FIG. 26) located on the glasses device 200 to display the display device 100. You can enter a video call connection command. In addition, the video call can be terminated by pressing the video call connect / end button again (see 240 'in FIG. 26) to end the video call.

In various embodiments of the present disclosure, the interface unit 150 may detect a user motion using data captured by the imaging unit 191 (or may be the same as the above-described imaging unit 170 according to an embodiment). It may include a detector (not shown). That is, when the video call receiving unit 192 described later first receives a video call request, the image capturing unit 191 may capture an image and detect a user's motion using the captured data.

The motion detector (not shown) is a component that recognizes a motion of an object located outside the display apparatus 100. Specifically, the motion detector (not shown) senses a motion of a user who intends to use the display apparatus 100 to recognize what motion has been performed. To this end, the motion detection unit (not shown) captures an object such as a user existing within the imaging range of the imaging unit 191, and analyzes the captured image data. That is, the change of the pixel value is tracked by comparing the first imaged image data with the image data imaged for a predetermined time thereafter. For example, when a video call request is received, when the imaging unit 191 performs imaging for a predetermined time, the motion detection unit (not shown) starts to compare the image data captured every moment. If there is no change in the pixel value of the image data photographed continuously for a certain time, or only a minute change in the error range is detected, motion detection is considered to be a failure. On the other hand, if there is a change in the pixel value of the image data captured for a certain time, and the change exceeds a certain threshold value, it can be seen that motion is detected. At this time, the motion detection unit (not shown) determines the direction, the change range and the position where the pixel value of the image data is changed to identify what motion is actually performed by the user. If the motion detection unit (not shown) determines that the identified motion matches the already set motion, the motion detection unit (not shown) considers that a command corresponding to the motion is input, and the controller 160 controls the display apparatus 100 according to the command. Operate properly.

According to an embodiment of the present invention, the command corresponding to the motion may be a video call connection command. In this case, the controller 160 controls the video call processor 190 to connect a video call with a counterpart node that has transmitted a video call request, and shifts the imaging direction in the direction in which the motion is detected. ).

The image capturing unit 191 is configured to perform image capturing. In detail, the image capturing unit 191 is installed in the display apparatus 100 to capture a user wearing the spectacle apparatus 200 and transmit the captured image to a motion detection unit (not shown). 193). The imaging unit 191 includes all kinds of imaging means capable of capturing a moving image or a still image, and specifically includes a digital camera, an infrared camera, a line camera, and the like. In addition, the above-described imaging unit 170 may be part of a configuration or a separate configuration.

According to an embodiment of the present invention, the imaging unit 191 may transmit the captured data to the above-described motion detection unit (not shown) for motion detection. In this case, the imaging data may be image data composed of successive frames, and the motion sensing unit analyzes the imaging data to track the change and thus recognize the motion performed by the user. When the motion is detected, the controller 160 controls the video call processor 190 to connect the video call with the counterpart node that sent the video call request, and controls the imaging unit 191 to capture the direction of motion in the direction in which the motion is detected. The imaging unit 191 is controlled to shift the control unit. The operation of the video call processing unit 190 will be described later. Hereinafter, the principle of shifting the imaging direction by the imaging unit 191 will be described. However, this is only an embodiment to help understanding of the present invention, and it is clear that the present invention does not exclude various technical means for controlling the imaging of the imaging unit 191. The imaging unit 191 may be located at the top center of the display apparatus 100 as shown in FIG. 19. The imaging unit 191 photographs all objects having a constant resolution and an imaging angle and falling within the range of the imaging angle. According to the above-described embodiment, when the motion detection unit (not shown) recognizes the video call connection motion of the user in the range of the imaging angle, the controller 160 may determine the image capture unit based on the position information on which the motion is recognized on the captured image. 191 and calculates the left and right rotation angle, the distance to the object. The controller 160 moves the imaging unit 191 by rotating the imaging unit 191 so that the point where the object is located coincides with the center point of the captured image of the imaging unit 191, and the object is sufficiently introduced into the imaging screen in consideration of the distance to the object. A zoom of 191 is pulled or stretched to obtain a video condition necessary for a video call. For example, when the video call connection motion is performed at the right 15 degrees and the upper 17 degrees from the center point of the image capturing screen of the image capturing unit 191, the controller 160 is configured to match the center point of the image captured by the image capturing unit 191. The image capturing unit 191 is moved, and a zoom of the image capturing unit 191 is pulled so that the upper body of the user enters the image capturing screen of the image capturing unit 191.

In addition, the imaging unit 191 may transmit the imaged data to the call screen processing unit 193 in order to configure a call screen. The call screen processing unit 193, which will be described later, receives the image data from the image capturing unit 191 to configure a call screen. The detailed operation of the call screen processing unit 193 will be described later. On the other hand, the data captured by the imaging unit 191 is transmitted to the video call device (not shown) of the other party of the user who is performing a video call through the display apparatus 100 by a transmitting unit (not shown) of the display apparatus 100. Can be delivered.

The video call receiving unit 192 is configured to receive video call data from a counterpart node that transmits a video call request when the video call is connected. Video call data includes all kinds of transmission and reception data for a video call. That is, audio data and image data can be transmitted in the form of line signals or packet signals. The video call data received through the video call receiving unit 192 is transferred to a call screen processing unit 193 described later and used to configure a call screen on the output unit 130.

The call screen processing unit 193 composes a video call screen using the image data and the image data. That is, the video call screen is configured on the output unit 130 by receiving the image data received through the video call receiving unit 192 and the captured image data captured by the image capturing unit 191. The controller 160 controls the output unit 130 to display the video call screen on the output unit 130, which will be described later. In an exemplary embodiment, the video call screen may include a large screen of the counterpart of the video call on the output unit 130 and a small screen of the user who inputs the video call connection command on the output unit 130 as shown in FIG. 19. It may be in the form.

Hereinafter, the control unit 160 in the present embodiment will be described.

First, when a video call connection command is input through the interface unit 150, the controller 160 controls the video call processor 190 to connect a video call with a correspondent node that has sent a video call request. . The video call processing unit 190 receives a video call request of the counterpart node and starts a video call when a video call connection command is input. That is, the image data transmitted from the other party may be signal processed and transmitted to the output unit 130, and the audio data may be decoded and modulated and transmitted to the display apparatus 100. Signal processing for the image data may be processed using the signal processing unit 120 of the display apparatus 100 after being processed in accordance with the reception protocol of the signal processing unit 120 of the display apparatus 100 described above, or a separate signal. It may be processed and displayed through a processing unit (not shown).

Second, when the video call is connected, the control unit 160 replaces the video frame of the content corresponding to the eyeglass apparatus 200 which has transmitted the video call connection command among the plurality of eyeglasses 200 to the video call screen. 130 can be controlled. That is, when any one user who wears the spectacles 200 and watches different content starts a video call with the other party, the output unit 130 displays an image frame of the content that the user is watching. Replace with video frame for video call screen. For example, FIG. 24 illustrates that one user views one content including image frame 1-1, image frame 1-2, image frame 1-3, and the like, and another user views image frame 2-1 and image frame 2. The video data stream in the case of viewing other content composed of -2, video frames 2-3, and the like is shown. In this case, the video frame of the content viewed by the user who started the video call is replaced with a frame (video call-1, video call-2, video call-3) representing the video call screen. When two users watch different content from the beginning, a video call can be made only by swapping video frames without changing the frame rate. However, there may be a case where a plurality of users wearing the spectacles are watching the same content. In this case, when the video call is connected, another user should be able to make a video call without affecting the user who does not perform the video call continuously watching the same content. Therefore, the above-described frame rate converter 122 doubles the frame rate of the content provided by the video processor 121, and the output unit 130 displays the video frame of the originally displayed content and the video frame for the video call screen. Are displayed alternately. In this case, the video frame for the video call screen may not reach the screen size or resolution provided by the display apparatus 100, and thus an additional correction or upscaling operation may be performed.

Third, when the above-described motion detector (not shown) detects a preset user motion by analyzing the image data, the controller 160 connects the video call to the counterpart node that transmitted the video call request. ) Can be controlled. Subsequently, the imaging unit 191 is controlled to shift the imaging direction in the direction in which the user motion is detected. Operations of the motion detector, the video call processor 190, and the image capturer 191 are the same as described above.

Fourth, when the video call request is received, the controller 160 may control the output unit 130 to display a message for inquiring whether to perform the video call. As described above, although the motion detection unit (not shown) may detect the motion of the user and connect the video call, the output unit 130 may ask whether or not the call is made. In this case, the user may connect the video call through the interface unit 150 described above. As described above, the video call connection / end button (see 240 ′ in FIG. 26) provided in the spectacle frame portion of the spectacle device may be an embodiment. However, in the present invention, various visual means may be used to ask whether a video call is performed, and various recognition means as well as visual means may be utilized.

Hereinafter, a video call method according to the present invention will be described with reference to FIGS. 21, 23, and 25. Since the operation of the specific configuration has been described above, the overall operation will be described schematically here.

When a plurality of users are wearing the glasses 200 and watching different contents (S2110, s2301, S2510) when there is a video call request (S2120-Y, S2310-Y, 920-Y), the user receives the same. S2130, S2315, S2530). In this case, the user who wears the glasses 200 and watches the content may respond to the video call request, and the display apparatus 100 may display a message for inquiring whether or not to perform the video call (S2540). The intention of response may be input as a video call connection command through the interface unit 150 (S2320-Y), and the motion detection method using the captured image of the user may be an embodiment (S2330). When a video call connection command input through the interface unit 150 or a motion corresponding thereto is detected (S2335-Y), the video call is started (S2335). When the video call is started, one content video frame of the plurality of contents is replaced with a video call screen (S2150, S2355, and S2560). Therefore, other users who were watching different contents can continue to watch their contents without any interruption. However, when several users are watching one content, the frame rate is adjusted and the video call screen is alternately arranged to display the content. On the other hand, when the video call is started by detecting the motion of the user, the imaging unit may configure an appropriate video call screen by shifting the imaging direction in the direction in which the motion is detected (S2340). When a video call is made, a video call screen can be constructed using the video call data received from the counterpart node and the imaging data picked up by the imaging unit (S2345 and S2350). In operation S2360, the voice data included in the video call data may be processed and transmitted to the eyeglass apparatus that has transmitted the video call connection command. When the video call ends, the original content is continuously displayed (S2160-Y, S2365-Y, S2570-Y).

Hereinafter, the spectacle device 200 according to the present embodiment will be described.

FIG. 26 is a block diagram illustrating a configuration of an eyeglass device 200 according to various embodiments of the present disclosure. In particular, the glasses device 200 of FIG. 26 is interlocked with the display device 100 that alternately displays a plurality of contents in image frame units, and the video call connection / end button 240 ' More).

The video call connection / end button 240'is configured to connect or end the video call. When a user receives a video call (i.e., receives a video call request from the display device), the user presses the video call connect / end button 240 'located on the glasses device 200 to send a video call connect command to the display device 100. You can enter In addition, the video call can be terminated by pressing the video call connect / end button 240 'again to end the video call.

As described above, the controller 220 controls the shutter glass driver 230 to generate driving signals for driving the first shutter glass unit 250 and the second shutter glass unit 260 based on the synchronization signal. . When the video call connection is made while several users are watching different contents, different contents are already mixed and displayed on the display apparatus 100, so a separate synchronization process is not necessary. However, when not in a multi-view situation, that is, when the same call is made to one user while watching the same content, the display apparatus 100 switches to the multi-view as described above, and thus the display apparatus 100 And synchronization is required. In this case, the controller drives the first shutter glass unit 250 and the second shutter glass unit 260 according to the synchronization signal transmitted from the display apparatus 100. However, when the video call is ended and the display is switched to the same content, the controller stops the operations of the first shutter glass unit 250 and the second shutter glass unit 260.

Hereinafter, referring to FIG. 27, a polarization method that may be applied when contents are alternately displayed or mixed and displayed is described.

The display apparatus 100 described above may further include a polarization member 180. The polarizing member 180 may include a liquid crystal layer (not shown) to polarize an image. The display apparatus 100 controls the liquid crystal layer for each horizontal line or vertical line by using driving voltages having different levels, and polarizes an image of the content emitted from the display apparatus 100 in a specific direction. At this time, the image of the polarized content may be alternately arranged and displayed. For example, one content can be polarized horizontally for display and then vertically polarized for other content for display and this process is repeated. Each image may be viewed through the spectacle apparatus 200-3 having the horizontal polarizing lens and the spectacle apparatus 200-4 having the vertical polarizing lens. In another embodiment, image information of different contents may be included in different regions of one image frame. In this case, each area may be polarized and displayed in a different direction, and viewing is possible through a spectacle device having a lens that matches the polarization direction.

In this case, the spectacles 200-3 and 200-4 used to view the display apparatus 100 may include polarized lenses that match the polarization direction of the content to be viewed. This allows each spectacle device to pass only the polarized image, so that the user can watch only the desired content. Since the glasses 200-3 and 200-4 do not need a separate synchronization operation with the display apparatus 100, the economical efficiency is high and the flicker occurring in the synchronization process is also reduced. FIG. 27 illustrates a case where an image is viewed with the spectacle apparatus 200-3 or 200-4 with polarizing lenses suitable for the case where image frames of contents polarized in the horizontal direction and the vertical direction are displayed alternately. Doing.

When the system is used for a video call, any one of the plurality of polarized images as described above may be replaced with a video call screen. That is, the display apparatus 100 polarizes an image of an area corresponding to a video call screen of a screen (display unit) while receiving and alternately displaying video call data and polarizing in a specific direction while displaying alternately.

According to the present invention, several people can view different contents through one display apparatus 100 including the above-described configuration, and can make a video call without affecting the viewing of other people.

30 is a block diagram of a display apparatus 100 further including an interface unit 150 and a video call processor 190 according to various embodiments of the present disclosure. FIG. 31 is a view illustrating the display apparatus 100 of FIG. 30. 32 is a flowchart illustrating a process of performing a video call using FIG. 32 is a conceptual diagram illustrating that a video frame of a content is replaced with a video frame for a video call screen, and FIG. FIG. 34 is a conceptual diagram illustrating a situation in which the display of the video is terminated due to the termination of the display, and FIG. 34 is a diagram illustrating storing the video frame of the content replaced by the video call screen in the storage unit 180, and FIG. A flowchart illustrating a process of performing a video call including displaying a message inquiring whether to make a call.

The storage unit 180 is a component for storing image frames of content. In detail, when the video call is started, the video frame of the content which has been displayed from that point but is replaced with the video call screen and is not displayed is stored. As described above, when a video call is connected while a user is watching the content, the video frame of the content is replaced with the video call screen, so that the user can no longer watch the content. If the display apparatus 100 receives and displays contents from various recording medium reproducing apparatuses stored in the display apparatus 100 or connected to the display apparatus 100 from the beginning, the contents of which the viewing is stopped after the video call ends In order to continue watching, the user only needs to receive and display the content stored in the display apparatus 100 or the recording medium reproducing apparatus again. However, there may be a case in which a limitation may be applied to receiving and displaying content in time or economically, such as receiving content in real time using a broadcast network or the Internet. In addition, even if there is no such time or physical limitation, in the case of continuous content such as a movie, it should be possible to continue watching from the time when the viewing is stopped while starting a video call. For example, as shown in FIG. 33, a user may be in a video call with his nephew while watching a drama, and an important scene of the drama being watched during the video call with the nephew is overdone or the drama is over. Can come out. At this time, if the broadcast time of the drama is limited, the user may not be able to re-view for a while, re-view is possible, but may have to pay a separate fee. In addition, even if it is possible to receive and watch a drama again, it is inconvenient to search until the point where the viewing is stopped. When the video call is started through the storage unit 180 as described above, the present invention stores the video frame of the content which was not displayed but was replaced by the video call screen. When the video call ends, the controller 160 controls the output unit 130 to display a combination of video frames stored in the storage unit 180 and video frames of contents not replaced with the video call screen. Therefore, even when a user makes a video call while watching the content, the user can store the content he / she is watching in the storage unit 180 and then watch again when the video call ends. The storage unit 180 may be various recording medium reproducing apparatuses present in or connected to the display apparatus 100. The recording medium reproducing apparatus means a device capable of reproducing contents stored in various types of recording media such as CD, DVD, hard disk, Blu-ray disc, memory card, USB memory, and the like.

Hereinafter, the control unit 160 according to the present embodiment will be described. In addition to the following description, the contents of the controller 160 are the same as in the above-described embodiment.

When the video call is connected in response to the video call request, the controller 160 controls the storage unit 180 to store a video frame of the content that is replaced with the video call screen, and when the video call ends, the controller 160 stores the video frame and the video call. The output unit 130 may be controlled to display a combination of image frames of content not replaced with a screen. As an example, FIG. 32 illustrates that one user views one content including image frame 1-1, image frame 1-2, image frame 1-3, and the like, and another user views image frame 2-1 and image frame 2-. The video data stream in the case of watching other content composed of 2, video frames 2-3 and the like is shown. As described above, the video frame of the content watched by the user who started the video call is replaced with a frame (video call-1, video call-2, video call-3) representing the video call screen. At this time, the controller controls the video frames 1-2, 1-3, and 1-4 replaced with frames (video call-1, video call-2, video call-3) representing each video call screen as shown in FIG. The storage unit 180 controls to store the contents of the ..). Then, when the video call ends, the video frames (1-2, 1-3, 1-4 ...) of the content stored in the storage unit 180 and the video frames (2- of other content not replaced by the video call screen). The output unit 130 may be controlled to display a combination of n, 2- (n + 1), ...). Operations of the storage unit 180 and the output unit 130 have been described above.

Hereinafter, a video call method according to the present invention will be described with reference to FIGS. 29, 31, and 34. Since the operation of the specific configuration has been described above, the overall operation will be described schematically here.

When a plurality of users are wearing the glasses 200 and watching different contents (S2910, S3105, S3510) when there is a video call request (S2920-Y, S3110-Y, 1120-Y), they receive the same. S2930, S3115, S3530). In this case, the user who wears the glasses 200 and watches the content may respond to the video call request, and the display apparatus 100 may display a message for inquiring whether or not to perform the video call (S3540). Response display of the response may be input as a video call connection command through the interface unit 150, the motion detection method using the captured image for the user may be an embodiment (S3120, S3125). If a video call connection command input through the interface unit 150 or a motion corresponding thereto is detected (S3130-Y), the video call is started (S3135). When the video call is started, one content video frame of the plurality of contents is replaced with a video call screen (S2950, S3155, and S3560). Therefore, other users who were watching different contents can continue to watch their contents without any interruption. However, when several users are watching one content, the frame rate is adjusted and the video call screen is alternately arranged to display the content. On the other hand, when the video call is started by detecting the motion of the user, the imaging unit may configure an appropriate video call screen by shifting the imaging direction in the direction in which the motion is detected (S3140). When a video call is made, a video call screen can be constructed using the video call data received from the counterpart node and the imaging data picked up by the imaging unit (S3145 and S3150). In addition, the video frame of the content replaced by the video call screen is stored in the storage unit (S2960, S3160, S3570). In operation S3165, the voice data included in the video call data may be processed and transmitted to the glasses apparatus which has transmitted the video call connection command. When the video call ends (S2970-Y, S3170-Y, S3580-Y), the stored video frame and the video frame of the content not replaced by the video call screen are displayed in combination (S2980, S3175, and S3590).

36 is a block diagram illustrating a configuration of an eyeglass device 200 according to various embodiments of the present disclosure. In particular, the spectacle apparatus 200 of FIG. 36 is interlocked with the display apparatus 100 that alternately displays a plurality of contents in image frame units, and includes an input unit 240, a controller 220, a shutter glass driver 230, The communication interface unit 210 includes a first shutter glass unit 250 and a second shutter glass unit 260.

Since the shutter glass driver 230, the communication interface unit 210, the first shutter glass unit 250, the second shutter glass unit 260, and the controller 220 have been described above, a detailed description will be given to avoid overlapping descriptions. Omit.

The input unit 240 is a configuration that can connect or terminate the video call (see Fig. 2). When a video call comes in (ie, when a video call request is received from the display device), the user may input a video call connection command to the display apparatus 100 through the input unit 240 located in the eyeglass apparatus 200. In addition, when the video call is terminated, the video call may be terminated through the input unit 240. The input unit 240 may be the same as or included in the video call connection / end button (240 ′ in FIG. 26) as described above.

Since the detailed configuration and function of the other glasses device 200 is included in the above-described embodiment, redundant description thereof will be omitted.

Display device contents  Example of Restricting View Switching

Hereinafter, a system and method for limiting switching of a content view by the display apparatus 100 according to various embodiments of the present disclosure will be described.

As shown in FIG. 5, the display apparatus 100 according to the present exemplary embodiment may include a plurality of receivers 110-1, 110-2,..., 110-n, and a plurality of signal processors 120-1, 120-2. ,..., 120-n), an output unit 130, a synchronization signal generator 140, an interface unit 150, and a controller 160.

Receiver 110-1, 110-2, ..., 110-n, Signal signal processor 120-1, 120-2, ..., 120-n, Output unit 130, Synchronization signal generation Since the unit 140 and the interface unit 150 have been described above, a detailed description thereof will be omitted in order to avoid duplicate descriptions, and the operation of the control unit 160 according to the present embodiment will be described.

The controller 160 may change an operation mode of the display apparatus 100 according to a user selection. The user may select one of various operation modes such as a single view mode (first mode) for viewing a single content and a multi view mode (second mode) for viewing a plurality of contents.

In the single view mode (first mode), one content such as 2D content or 3D content is output. In the multi view mode (second mode), a plurality of contents are combined and provided as a plurality of content views as described above. In the multi-view mode (second mode), the content view is maintained even when the content playback assigned to one content view ends and the next content starts playing.

When the two contents are combined and output, the multi view mode (second mode) may be called a dual view mode. The controller 160 controls the output unit 130 to combine and output a plurality of contents when the user inputs a mode switching command while operating in the single view mode (first mode). When switching to the multi-view mode (second mode), the controller 160 controls the synchronization signal generator 120 and the interface unit 130 to transmit a synchronization signal to each glasses device mapped to each content.

Meanwhile, a user who views one of the plurality of content views in the multi view mode (second mode) may input a content view switch command for performing a content view switch operation. The content view switching operation refers to an operation of switching a content view that can be viewed by a plurality of viewers who are watching each of the plurality of contents.

For example, when a content view switching operation is performed while a content view to which a broadcasting channel for broadcasting a news program is allocated and a content view to which a sports program is assigned are outputted in combination, the first user who is watching the news program is a sports user. The program is viewed, and the content view is switched so that the second user who was watching the sports program is watching the news program.

Alternatively, the content view switching operation may be performed such that only a user who inputs a content view switching command switches to another content view. That is, in the above example, if the first user inputs the content view switching command, the first user is switched to watching the sports program, and the second user is watching the sports program as it is.

The content view switching command may be received from a glasses device or a remote controller worn by a user, or may be input through a key button provided in the main body of the display apparatus 100.

When the content view switch command is input, the controller 160 performs the content view switch operation in a limited manner according to the type of content and the user's setting state.

Specifically, the controller 160 may limit the content view switching operation for the content view displaying the preset type of content and allow the content view switching operation for the content view displaying the remaining content. Contents for which the content view switching operation is restricted include, but are not limited to, a broadcast program screen of a parental level, which is prohibited from viewing by a minor, an execution screen of various game programs, an execution screen of a messenger program, an e-mail confirmation screen, or an SNS (Social Network Service) screen. This can be. Since the contents of the messenger, the mail, and the SNS message may be invaded in personal privacy, even if the contents view switch command is input, the contents view switch is prohibited. In addition, when a plurality of users executes a game program that competes with each other and each game screen is displayed in combination on one display apparatus 100, when the content view switching operation is performed, the strategy of another user may be secretly checked. . Therefore, even in this case, switching of the content view can be prohibited. In addition, even in the case of a broadcast program screen of a parental level, it is possible to prohibit switching of the content view in order to prevent a minor or the like from secretly watching. Information about the type of content for which the content view switching operation is restricted may be pre-registered in a memory (not shown) in the display apparatus 100 or may be provided from a separate external source.

According to another exemplary embodiment, the controller 160 may determine whether to perform or prohibit the content view switching operation according to a user's setting value. The controller 160 controls the output unit 130 to display a setting menu when the dual view mode is started, when new content is output under the dual view mode, when a setting command is input under the dual view mode, or the like. The output unit 130 displays a setting menu for setting whether to prohibit switching of the content view under the control of the controller 160.

If the user has set the content view switching allowance on the setting menu, the controller 160 performs a content view switching operation when a content view switching command is input later. On the other hand, if the user has set the content view switching prohibition through the setting menu, the controller 160 limits the content view switching operation even if the content view switching command is input.

37 is a view for explaining a content view switching process. According to FIG. 37, when the multi-view mode (second mode) is started, the display apparatus 100 displays the multi-content frame data 10 in which a plurality of contents are alternately arranged. The glasses apparatuses 210 and 220 corresponding to the respective contents are driven in synchronization with the display timing of the corresponding contents. Accordingly, a user wearing the first glasses device 210 can watch the first content C1, and a user wearing the second glasses device 220 can watch the second content C2.

In this state, when the content view switching command is input through the first glasses device 210, the second glasses device 220, or a separate input device such as a remote controller, the display device 100 arranges the contents C1 and C2. By inverting the above, the contents that can be viewed in the first glasses device 210 and the second glasses device 220 are switched to each other.

Although FIG. 37 illustrates a method of changing content viewable by the glasses apparatuses 210 and 220 by switching the arrangement of contents, the display apparatus 100 may perform a content view switching operation by changing a synchronization signal. . That is, the controller 160 controls the synchronization signal generator 140 to change the synchronization signals corresponding to the first glasses device 210 and the second glasses device 220 while maintaining the content arrangement order. The spectacles device 210 is synchronized to the display timing of C2 and the second spectacles device 220 is synchronized to the display timing of C1.

Meanwhile, as described above, the content view switching operation may be limited in some cases. 38 illustrates a state in which the content view switching operation is restricted.

According to FIG. 38, when the content is restricted according to the type of content or a user's setting value, the controller 160 does not perform the content view switching operation even when a content view switching command is input.

The controller 160 controls the output unit 130 to display an error message 20 for notifying when the content view switching operation is limited.

39 is a block diagram illustrating a configuration of a display apparatus according to another exemplary embodiment. Referring to FIG. 39, the display apparatus 100 includes an output unit 130, a synchronization signal generator 140, an interface unit 130, a controller 160, and an input unit 150.

The input unit 150 receives a user command such as a command for inhibiting content view switching. The user command may be input through a button or a remote controller provided in the main body of the display apparatus 100.

When the multi-view mode (second mode) is started and a plurality of contents are displayed on the output unit 130 and a content view switching prohibition command is input, the controller 160 displays content contents regarding the currently displayed contents. Even if a switching command is input, the switching operation is limited.

In addition, the input unit 150 may also receive a release command for releasing the prohibition of switching the content view.

In this case, the controller 160 limits the content view switching operation even when the content view switching command is input between the time at which the content view switching prohibition command is input and the time at which the release command is input.

Hereinafter, the spectacle device 200 according to various embodiments of the present disclosure will be described. The spectacle apparatus 200 according to the present embodiment may take the configuration of FIG. 9 described above.

That is, the spectacle apparatus 200 is interlocked with the display apparatus 100 that alternately displays a plurality of contents in image frame units, and includes a communication interface 210, a controller 220, a shutter glass driver 230, and a second device. And a first shutter glass unit 250, a second shutter glass unit 260, and an input unit 240.

Since the communication interface 210, the shutter glass driver 230, the first shutter glass unit 250, and the second shutter glass unit 260 have been described above, the control unit 220 and the input unit ( Only 240) will be described.

The input unit 240 receives a content view switch command. The input unit 240 may include a button for receiving a content view switch command, and the button may be implemented as a touch sensor or an operation button.

The controller 214 controls the interface unit 216 to transmit a content view change command input through the input unit 240 to the display apparatus 100. As described above, the display apparatus 100 performs the content view switching operation when the content view switching is allowed, and does not perform the content view switching operation when the display apparatus 100 is limited.

Hereinafter, a method of switching content views of a display apparatus according to an exemplary embodiment will be described.

39 is a flowchart illustrating a content view switching method of a display apparatus according to an exemplary embodiment.

Referring to FIG. 39, when the multi-view mode (second mode) is started, a plurality of contents are received and processed, respectively, to display image frames of the respective contents as a plurality of content views (S3910).

In operation S3920, a synchronization signal for synchronizing the glasses device corresponding to each content view is generated and transmitted to each glasses device (S3930).

In this state, when a content view switch command is received from the glasses device (S3940), it is determined whether to allow the content view switch (S3950). The display apparatus 100 may determine whether to allow to change the content view in consideration of the type of the content corresponding to each content view or the setting state of the user. For example, content view switching may be prohibited for a broadcast program screen of a parental level, which is prohibited from watching a minor, an execution screen of various game programs, an execution screen of a messenger program, a mail confirmation screen, or an SNS screen. In addition, even when the user has set the prohibition of switching, the content view switching may be prohibited.

When it is determined whether the restriction is determined according to the user's setting, the method may further include displaying a setting menu for setting whether to prohibit switching of the content view. If a content view switch command is input while a content view switch command is set through the setting menu, performing the content view switch operation; and the content view switch command with the content view switch prohibition set through the setting menu. If this is input, the method may further include limiting the content view switching operation.

As a result of determination, the display apparatus 100 performs content view switching (S3960), and if limited, prohibits content view switching (S3970). In this case, no feedback may be provided for the content view switch command, but a voice or visual error message may inform the fact that the content view switch is restricted.

40 is a flowchart illustrating a content view switching method of a display apparatus according to another exemplary embodiment.

Referring to FIG. 40, when the multi-view mode (second mode) is started, a plurality of contents are received and processed, and the image frames of the respective contents are displayed as a plurality of contents views (S4010).

Then, a synchronization signal for synchronizing the glasses device corresponding to each content view is generated (S4020) and transmitted to each glasses device (S4030).

In this state, if a content view switch prohibition command is received (S4040), even after the content view switch command is received, an error message is displayed (S4060) and the content view switch operation is not performed. On the other hand, when the content view switch prohibition command is not received, when the content view switch command is received (S4070), the content view switch is performed (S4080). Meanwhile, when the release command is input, the content view switch prohibition command is released, and content view switch may be performed without limitation. That is, the content view switching may be limited from the time point at which the content view change prohibition command is input to the time point at which the release command is input.

As described above, the display apparatus 100 may limit the content view switching function in some cases or at the request of the user while providing a content view switching function of switching and viewing the content view according to the user's convenience. As a result, the user can be prevented from exploiting the content view switching function.

Meanwhile, the program for performing the method according to various embodiments of the present disclosure described above may be stored and used in various types of recording media.

Specifically, such programs include random access memory (RAM), flash memory, read only memory (ROM), erasable programmable ROM (EPROM), electronically erasable and programmable ROM (EPROM), registers, hard disks, removable disks, and memory. It may be stored and provided in various types of recording media readable by a terminal, such as a card, a USB memory, a CD-ROM, and the like.

According to the directionality of the user signal corresponding glasses device Pairing  Example

Hereinafter, a system and method for displaying contents by pairing corresponding eyeglasses according to the direction of the user signal will be described.

FIG. 41 is a view schematically illustrating a single view mode (first mode) of a display apparatus according to an embodiment of the present invention, and FIG. 42 is a multi view mode (second view) of a display apparatus according to an embodiment of the present invention. Mode) is a diagram schematically shown.

The display apparatus 100 may operate in a single view mode (first mode) for displaying a single content and in a multi view mode (second mode) for alternately displaying a plurality of contents.

As illustrated in FIG. 41, a plurality of users may wear the glasses apparatuses 210 and 220, respectively, and watch the content 1. Of course, the single view mode (first mode) can be viewed without the eyeglasses is a matter of course.

As illustrated in FIG. 42, a plurality of users may view a multi-view mode (second mode) (content 1 and content 2) while wearing the glasses devices 210 and 220, respectively.

The remote controller 300 is provided with a touch pad 310 in response to a user's touch.

The spectacle apparatuses 210 and 220 are provided with light emitting devices 400 to detect the position detection of the spectacle apparatuses 210 and 220 in the display apparatus 100. Although the light emitting device 400 is described as being used in the present embodiment, this may be sufficient as long as the display device 100 can detect the positions of the spectacles 210 and 220.

The light emitting device 400 may use an IR LED.

The display apparatus 100 according to the present exemplary embodiment performs mode switching when a user signal having directionality is received from the remote controller 300. Specifically, when a user signal is received while operating in the single view mode (first mode), the user's eyeglasses that have input the user signal view the content currently displayed, and other content is used by the other user's eyeglasses. The user may switch to the multi-view mode (second mode) that displays a combination of the current content and the other content so as to view.

For example, when the user on the left wants to watch the content 1 in the multi view mode (second mode), the user on the left may touch or drag the flip pad to the left by touching the touch pad 310 of the remote controller 300. have. The remote controller 300 may generate a remote controller signal for notifying a direction in which the user drags or flips and transmits the generated remote controller signal to the display apparatus 100.

When the remote control signal is detected, the display apparatus 100 determines which user of the plurality of eyeglasses 210 and 220 has operated the remote control based on the direction included in the remote control signal. The display apparatus 100 may recognize the eyeglass apparatus of the user who operated the remote controller by comparing the position of each eyeglass apparatus and the touch direction included in the remote controller signal. For example, as described above, when the light emitting device such as an IR LED is provided in each of the eyeglasses 210 and 220 and the color of the corresponding light emitting device is different, the display apparatus 100 captures an image of the front of the display apparatus 100. The position of each spectacle device may be confirmed using the light emitting device color displayed on the image.

When the display apparatus 100 recognizes the user's eyeglasses 210 located on the left side, the display apparatus 100 controls the recognized eyeglasses 210 to view the currently displayed content, that is, the content 1, as it is, and the remaining users. Other content, that is, the content 2, or to view the content is processed to be impossible. Content 2 may be arbitrarily determined, such as a broadcast program received on the next channel of content 1.

As described above, the display apparatus 100 switches from the single view mode (first mode) to the multi view mode (second mode) according to a user's remote control operation. Therefore, when the user only wants to watch a specific content, the user may switch to the multi-view mode (second mode) with a simple touch operation to prevent the specific content from being exposed to other users.

43 is a block diagram illustrating a configuration of a display apparatus according to an exemplary embodiment. Referring to FIG. 43, the display apparatus 100 includes a plurality of receivers 110-1, 110-2,..., 110-n, and a plurality of signal processors 120-1, 120-2,. -n), an output unit 130, an imaging unit 180 ′, a sensing unit 170 ′, a controller 160, an interface unit 150, and a synchronization signal generator 140.

Since functions similar to the configuration, duplicate descriptions are omitted.

The interface unit 150 receives a user signal having directivity from the remote controller 300.

The imaging unit 180 ′ performs an imaging operation on a user including the glasses device 210 or 220. The imaging unit 180 ′ may be attached to one side of the display apparatus 100 to capture an image of the front of the display apparatus 100. Accordingly, the eyeglasses of all users who are watching the display apparatus 100 may be displayed on the image picked up by the imaging unit 180 '. The imaging unit 180' may be included in the imaging unit of the above-described embodiments, or the like. The functions can be performed together.

The detector 170 ′ detects the spectacle apparatuses 210 and 220 corresponding to the orientation by using the captured image captured by the imaging unit 180 ′.

For example, the sensing unit 170 ′ recognizes the colors of the light emitting devices 400 attached to the plurality of eyeglasses 210 and 220 included in the image captured by the imaging unit 180 ′, and then detects the colors of the light emitting elements 400. It is possible to detect which eyeglasses are located.

As another example, when the light emitting device is not attached to the spectacle apparatuses 210 and 220, the sensing unit 170 ′ may be attached to the shape, color, or spectacles of the spectacle apparatuses 210 and 220. The spectacles may be identified by recognizing the specific mark.

The detector 170 ′ provides the detection result to the controller 160.

When the user signal is input, the controller 160 controls the detector 170 ′ to detect the spectacle device that has input the user signal. Accordingly, when one eyeglass apparatus is detected as described above, the controller 160 switches to the multi-view mode (second mode) so that specific contents can be viewed by the detected eyeglass apparatuses 210 and 220.

Specifically, the controller 160 activates the other receiving unit which is in an inactive state, and controls to receive other contents. In addition, the signal processing unit 120-1, 120-2,..., To signal-process each content received by each of the receiving units 110-1, 110-2,. 120-n) and the output unit 130 are controlled. The controller 160 generates a synchronization signal for synchronizing the content view corresponding to the content previously displayed among the plurality of content views and the glasses device of the user recognized as input of the user signal, and transmits the synchronization signal to the corresponding glasses device. The unit 150 is controlled. In addition, the synchronization signal generator 140 and the interface unit 150 are controlled to generate a synchronization signal for synchronizing the remaining glasses devices with respect to the remaining content views and transmit them to the respective glasses devices. The content to be displayed in the remaining content views may be arbitrarily selected.

When switching to the multi-view mode (second mode), the synchronization signal generation unit 140 synchronizes the glasses apparatuses 210 and 220 sensed at the output timing of the contents among the plurality of contents, and stores the other contents among the plurality of contents. A synchronization signal for synchronizing the other eyeglasses 210 and 220 is output at an output timing.

Meanwhile, in the above-described embodiment, the display apparatus 100 generates synchronization signals corresponding to the display timing of the contents, and transmits them to the glasses apparatuses 210 and 220, but this is merely an example.

44 is a flowchart illustrating a multi-view switching method according to an embodiment of the present invention.

First, the content is displayed (S4410). In the present embodiment, for example, a single view mode (first mode) displaying a single content (content 1) is displayed.

Subsequently, a user signal having directionality is received from the remote controller 300 (S4420). The remote controller 300 is a remote controller 300 having a touch pad 310, and the user signal may be a user touch manipulation signal moving in one direction on the touch pad 310. In the present embodiment, it will be described as moving to the left by way of example.

When the user signal is input, the imaging operation is performed (S4430). The imaging operation may be performed with respect to the front of the display apparatus 100 by a camera attached to the display apparatus 100.

After the imaging operation, the spectacle apparatus 210 corresponding to the orientation is sensed among the plurality of spectacle apparatuses 210 and 220 included in the captured image (S4440). 41 and 42, the spectacle apparatus 210 on the left side is exemplarily used as the spectacle apparatus 210 corresponding to the orientation. The detecting of the spectacle device 210 may include recognizing a position of the light emitting device 400 attached to the plurality of spectacle devices 210 and 220 included in the picked-up image, and among the plurality of spectacle devices 210 and 220. The glasses device 210 corresponding to the direction is detected.

Thereafter, the display device 100 switches to the multi-view mode (second mode) so that the content (content 1) can be viewed on the detected glasses device 210 (S4450). In the multi-view mode (second mode) switching, the content (content 1) and the new content (content 2) are received by receiving the new content (content 2) using at least one other receiving unit in addition to the receiving unit receiving the content (content 1). Is displayed in combination. Switching to the multi-view mode (second mode) synchronizes the glasses apparatus 210 sensed at the output timing of the content (content 1) among the plurality of contents, and receives the output timing of the other content (content 2) among the plurality of contents. Outputting a synchronization signal for synchronizing the spectacles device 220.

Meanwhile, when the user inputs a preset touch pattern through the touch pad 310 of the remote controller 300 while watching in the multi view mode (second mode), the remote controller 300 enters the multi view mode (second mode). A remote controller signal for ending and switching to the single view mode (first mode) may be transmitted to the display apparatus 100. The preset touch pattern may be the same pattern as the pattern touched to operate in the multi-view mode (second mode), may be a pattern pointing in the opposite direction, or may be a specific shape pattern.

Accordingly, the user can simply switch between the single view mode (first mode) and the multi view mode (second mode) using the touch pad attached to the remote controller.

Meanwhile, the program for performing the method according to various embodiments of the present disclosure described above may be stored and used in various types of recording media.

Specifically, the code for performing the above-described methods may be stored in a storage medium such as a RAM (Random Access Memory), a FLASH memory, a ROM (Read Only Memory), an EPROM (Erasable Programmable ROM), an EEPROM (Electronically Erasable and Programmable ROM) Such as a floppy disk, a removable disk, a memory card, a USB memory, a CD-ROM, and the like.

Hereinafter, a system and method for recording and transmitting multi-view mode (second mode) information in the synchronization signal according to various embodiments of the present disclosure will be described.

According to various embodiments of the present disclosure, the display apparatus 100 may include a plurality of receivers 110-1, 110-2,..., 110-n, and a plurality of signal processors 120-1, 120-2,. , 120-n), an output unit 130, a synchronization signal generator 140, an interface unit 150, a controller 160, and an input unit 170 ″.

A plurality of receivers 110-1, 110-2, ..., 110-n, a plurality of signal processors 120-1, 120-2, ..., 120-n, output unit 130, synchronization The signal generation unit 140, the interface unit 150, and the control unit 160 may perform the functions of the above-described configuration corresponding to each other except the contents described below.

The input unit 170 ″ receives a multi-view watching command. The multi-view viewing command refers to a user command that the display apparatus alternately displays a plurality of contents in image frame units in order to provide different contents to a plurality of users.

To this end, the input unit 170 ″ may be implemented as a touch pad, a key button, a keypad, or the like, or may be implemented to receive a user command input from a remote controller (not shown) such as a remote controller. In addition to the multi-view viewing command, the input unit 170 ″ may receive various user commands for controlling the display apparatus 100 such as a channel tuning command and a volume adjustment command.

When the multi-view viewing command is input, the controller 160 may control the interface unit 150 to record and transmit multi-view mode (second mode) information in the synchronization signal. Here, the multi-view mode (second mode) information includes information for notifying the start of the multi-view mode (second mode). The spectacle apparatus determines whether the display apparatus 100 operates in the multi-view mode (second mode) according to whether the received synchronization signal includes the multi-view mode (second mode) information, and opens / offs the shutter glass unit. To control.

The controller 160 generates a synchronization signal according to a communication protocol defined between the at least one eyeglasses device, and records the multi-view mode (second mode) information in the reserve area in the synchronization signal. That is, the controller 160 generates a synchronization signal in which the multi-view mode (second mode) information is recorded according to a wireless communication method performed by the interface unit 150, and transmits the synchronization signal to the spectacle apparatus to be described later. 150 may be controlled.

The interface unit 150 transmits a synchronization signal to at least one eyeglass device that interworks with the display apparatus 100. In this case, the interface unit 150 may process the synchronization signal according to various wireless communication schemes and transmit the synchronization signal to the spectacles.

For example, when the interface unit 150 includes a Bluetooth communication module to communicate with the glasses device, the controller 160 generates a synchronization signal as a transmission packet according to a Bluetooth communication method and transmits the generated packet to the glasses device. 150 may be controlled. Hereinafter, a transmission packet generated according to a Bluetooth communication scheme will be described in more detail with reference to FIG. 46.

46 illustrates a structure of a transport packet generated according to a Bluetooth communication scheme according to an embodiment of the present invention.

As shown in Fig. 46, the transport packet includes time information for opening / off the shutter glass of the spectacle device in synchronization with the display timing of the content. Specifically, the time information may include an offset time for opening the left eye shutter glass of the spectacle device, a left shutter close offset for turning off the left eye shutter glass, and an offset time for opening the right eye shutter glass. open offset), and information on the right shutter close offset of turning off the right eye shutter glass, which consists of a packet of two bytes.

Here, the time information refers to time information for opening / off the shutter glass of the spectacle apparatus according to the display timing of one of the plurality of contents in the multi view mode (second mode). In the normal mode, the time information refers to time information for opening / off the shutter glass of the spectacle device according to the display timing of the left eye image frame and the right eye image frame of the 3D content.

On the other hand, the offset time is delay information from the reference time set for each content to the opening or off time of the shutter glass. That is, the spectacle apparatus opens / offs the left eye shutter glass and the right eye shutter glass when the offset time has elapsed from the reference time point. For example, the reference time point may be a time point at which a vertical sync signal (ie, frame sync) is generated in an image frame, and information about the reference time point may be included in a transport packet. In addition, information about a clock signal used in the display apparatus 100 may also be included in the transport packet.

That is, as shown in FIG. 46, information about a reference time point and information about a clock signal are included in a 4-byte BT (Bluetooth) clock packet and a 2-byte BT clock phase packet in a transport packet. Accordingly, upon receiving the transport packet, the spectacle device synchronizes its clock signal to the clock signal of the display apparatus 100 using the BT clock packet and the BT clock phase packet, and generates a vertical synchronization signal using the clock signal. The shutter glass may be opened / off by determining whether the offset time has been reached from the viewpoint.

Meanwhile, a BT clock including reference view information and clock signal information in a 4-byte BT clock packet may be composed of 28 bits, and the remaining 4 bits may be reserved areas. The controller 160 records the multi-view mode (second mode) information in the reserve area in the BT clock packet. For example, when the display apparatus 100 provides one 3D content, the controller 160 records '0' in the reserve area (normal mode), and when the plurality of contents are alternately displayed, the multi-view mode (first '1' can be recorded in the reserve area as the (mode 2) information (multi-view mode (second mode)). The spectacles check the information recorded in the reserve area, determine an operation mode of the display apparatus 100, and perform an operation corresponding to each mode. Specifically, the eyeglass apparatus simultaneously opens / offs the left eye shutter glass and the right eye shutter glass based on the time information when '1' is recorded in the reserve area, and the left eye based on the time information when '0' is recorded in the reserve area. The shutter glass and the right eye shutter glass are alternately opened / off.

In addition, the transport packet is a two-byte packet (frame sync period) including information on the period of the frame sync, when the frame sync period has a decimal point, a packet of one byte to indicate the decimal point information (frame sync fraction) ), A 1-byte packet Trem including information on the remaining playback time of the 3D content that the user is currently watching, and a 1-byte packet Tdis including information about the degree of opening of the spectacle device. Can be.

Meanwhile, the interface unit 150 transmits / receives a Bluetooth device address, a pin code, and the like with the glasses device, and performs pairing according to a Bluetooth communication method. When the pairing is completed, the interface unit 150 may transmit a synchronization signal corresponding to one of the plurality of contents to the glasses device based on the information obtained through the paying.

In addition, when pairing with a plurality of eyeglasses is completed, the interface unit 150 may transmit the same or different synchronization signals to different eyeglasses based on the information obtained through the paying. In addition, the interface unit 150 may transmit the same synchronization signal to some eyeglasses. For example, the interface unit 150 may transmit a synchronization signal corresponding to the content 1 to the glasses device 1, a synchronization signal corresponding to the content 2 to the glasses device 2, and a synchronization signal corresponding to the content 1 to the glasses device 3.

Although the above-described embodiment has been described as the interface unit 150 and the spectacle device performing communication according to the Bluetooth communication method, this is only an example. That is, in addition to the Bluetooth method, it is possible to use a communication method such as infrared communication, Zigbee, etc., and to perform communication according to various wireless communication methods capable of transmitting and receiving signals by forming a communication channel in other local areas. .

In addition, in the above-described embodiment, the display apparatus and the eyeglass apparatus communicate with each other according to various wireless communication methods capable of transmitting and receiving signals by forming a communication channel at a short distance, but this is merely an example. That is, the display device provides an IR (Infra Red) synchronization signal having a different frequency to the glasses device, the glasses device receives a synchronization signal having a specific frequency, and open or off the shutter glass in accordance with the display timing of the corresponding content Of course you can.

Meanwhile, in the above-described embodiment, the display apparatus 100 generates synchronization signals corresponding to the display timing of the contents, and transmits them to the glasses apparatus 200. However, this is merely an example.

That is, the controller 160 may control the interface unit 150 to generate a synchronization signal corresponding to the display timing of each content as one transport packet according to the Bluetooth communication standard. That is, the interface unit 150 synchronizes the display timing of the first content to open / off the shutter glass of the spectacles device, and synchronizes the display of the second content to open / off the shutter glasses of the spectacles device. Time information, ..., and one transmission packet including all the time information for opening / off the shutter glass of the spectacle device in synchronization with the display timing of the n-th content.

In this case, the interface unit 150 may generate a transport packet by matching the information on the spectacles with the display timing of each content. For example, the interface unit 150 may match information about different glasses devices for each content in the order in which the image frames of the content are arranged. That is, when two contents are provided in the multi-view mode (second mode), the image frames of the first, third, ..., n-th arranged image frames match the information about the spectacle device 1, The image frames of the contents arranged in the fourth, fourth, ..., n + 1th may match the information about the spectacle device 2 (where n is odd). In addition, the interface unit 150 may transmit a transmission packet generated to include a synchronization signal for each of the plurality of contents to the spectacles. The spectacle device may open / off the shutter glass by using a synchronization signal including its spectacle device information among the synchronization signals for each of the plurality of contents.

47 is a block diagram illustrating a configuration of an eyeglass device according to an exemplary embodiment. As illustrated in FIG. 47, the spectacle device 200 includes a communication interface 210, a controller 220, a shutter glass driver 230, a first shutter glass unit 250, and a second shutter glass unit 260.

The communication interface 210 receives a synchronization signal from the display device. In detail, the communication interface 210 may communicate with the display apparatus according to various wireless communication methods to receive the synchronization signal. For example, the communication interface 210 may include a Bluetooth communication module to perform communication with a display device according to a Bluetooth communication method.

As described above, the synchronization signal may be received in the form of a transmission packet according to the Bluetooth communication method, and synchronized with the display timing of the content, the first shutter glass unit 250 and the second shutter glass unit ( 260 may include time information for opening / off. Since the information included in the transport packet has been described above with reference to FIG. 46, duplicate description thereof will be omitted.

The controller 220 controls the operation of the first half of the spectacles 200. In particular, the controller 220 transfers the synchronization signal received from the communication interface unit 210 to the shutter glass driver 230 to control the operation of the shutter glass driver 230.

Specifically, when the multi-view mode (second mode) information is included in the synchronization signal, the controller 220 may include the first shutter glass unit 250 and the second shutter glass unit according to the multi-view mode (second mode) information. The shutter glass driver 230 is controlled to adjust the open timing of the 260.

For example, when the synchronization signal is received in the form of a transmission packet according to the Bluetooth communication scheme, the controller 220 confirms whether the multi view mode (second mode) information is included in the reserve area in the transmission packet, The shutter glass driver 230 is controlled to generate driving signals for driving the first shutter glass unit 250 and the second shutter glass unit 260 according to whether the view mode (second mode) information is included.

In detail, when the 3D content is displayed on the display device, the controller 220 alternately opens the first shutter glass unit 250 and the second shutter glass unit 260, and the multi-view mode (second mode) information is displayed. When the included synchronization signal is received, the first shutter glass unit 250 and the second shutter glass unit 260 are opened according to the display timing of the content corresponding to the spectacles 200 among the plurality of contents displayed on the display apparatus. .

That is, when it is determined that the multi-view mode (second mode) information is not included in the synchronization signal, the controller 220 based on the time information included in the synchronization signal, the first shutter glass unit 250 and the second shutter glass. The shutter glass driver 230 is controlled to generate a driving signal for alternately opening / off the unit 260. Accordingly, the first shutter glass unit 250 and the second shutter glass unit 260 may be opened / off in synchronization with the display timing of the left eye image frame and the right eye image frame of the 3D content.

If it is determined that the multi-view mode (second mode) information is included in the synchronization signal, the controller 220 may include the first shutter glass unit 250 and the second shutter glass unit based on the time information included in the synchronization signal. The shutter glass driver 230 is controlled to generate a driving signal for opening / off all of the signals 260. Accordingly, the first shutter glass unit 250 and the second shutter glass unit 260 may be opened when an image frame of one of a plurality of contents is displayed.

Meanwhile, in the above-described embodiment, the display apparatus 100 generates synchronization signals corresponding to the display timing of the contents, and transmits them to the glasses apparatus 200. However, this is merely an example. That is, the display apparatus 100 may generate a synchronization signal corresponding to the display timing of each content as one transport packet according to the Bluetooth communication standard and transmit the synchronization signal to the spectacles device.

48 is a flowchart illustrating a multi-view display method of a display apparatus according to an exemplary embodiment.

First, a multi-view viewing command is input (S4810). The multi-view viewing command refers to a user command that the display apparatus alternately displays a plurality of contents in image frame units in order to provide different contents to a plurality of users.

Thereafter, when a multi-view viewing command is input (S4810-Y), a plurality of contents are displayed (S4820). In detail, when a multi-view viewing command is input, a plurality of different contents are received to form image frames of each of the plurality of contents, and image frames of each of the plurality of contents are alternately arranged and displayed.

In operation S4830, a synchronization signal including multi-view mode (second mode) information is generated. The multi-view mode (second mode) information is information for notifying the fact when the multi-command viewing is input, and includes information for notifying the start of the multi-view mode (second mode).

The multi-view mode (second mode) information may be recorded in a reserve area of a synchronization signal generated according to a communication protocol defined between at least one eyeglass device. For example, when the synchronization signal is generated in the form of a transport packet according to the Bluetooth communication scheme, the multi-view mode (second mode) information may be recorded in the reserve area in the BT packet. This has been described above with reference to FIG. 46.

Thereafter, the synchronization signal is transmitted (S4840). In detail, the synchronization signal is transmitted to at least one eyeglass device that cooperates with the display device. For example, in the case of the Bluetooth communication method, a device ID and the like acquired during the pairing process are matched to a transport packet including time information corresponding to the display timing of each content. Then, the transmission packet is transmitted to the corresponding glasses device based on the information obtained through pairing.

49 is a flowchart for explaining a method of controlling the glasses device, according to an exemplary embodiment. In particular, FIG. 49 illustrates a control method of the spectacle device which interlocks with the display device and opens the first and second shutter glasses according to the display timing of the content displayed on the display device.

First, a synchronization signal is received from the display device (S4910). To this end, communication with the display device may be performed according to various communication methods.

Thereafter, it is determined whether the multi-view mode (second mode) information is included (S4920). For example, when receiving a transport packet generated according to a Bluetooth communication method, it is determined whether the multi view mode (second mode) information is included in the reserve area in the transport packet.

If the multi-view mode (second mode) information is included in the synchronization signal (S4920-Y), the opening timing of the first and second shutter glass units is adjusted according to the multi-view mode (second mode) information (S4930).

Specifically, when the 3D content is displayed on the display device, when the first and second shutter glass parts are alternately opened and a synchronization signal including the multi-view mode (second mode) information is received, a plurality of displayed on the display device is displayed. The first and second shutter glasses may be opened at the display timing of the content corresponding to the spectacles of the glasses. Accordingly, the user can watch 3D content in the normal mode and one of the plurality of contents in the multi-view mode (second mode).

Meanwhile, the program for performing the method according to various embodiments of the present disclosure described above may be stored and used in various types of recording media.

An embodiment of the spectacle apparatus that provides information on whether the spectacle apparatus is normally operated

Hereinafter, a description will be given of an eyeglass device for providing information on whether the eyeglasses normally operate when providing contents according to various embodiments of the present disclosure.

50 is a block diagram illustrating a configuration of a display apparatus according to various embodiments of the present disclosure.

Referring to FIG. 50, a display apparatus according to various embodiments of the present disclosure may include a plurality of receivers 110-1, 110-2,..., 110-n, and a plurality of signal processors 120-1, 120-2. , 120-n), an output unit 130, a synchronization signal generator 140, an interface unit 150, a controller 160, and an audio data transmitter 170. In addition to the contents described below, the components perform the functions of the corresponding components described above, and overlapping descriptions will be omitted.

When the connection request message for transmitting the synchronization signal is received from the spectacles device, the controller 160 controls the audio data transmitter 170 to transmit audio data corresponding to one content to the spectacles device.

When the connection request message is received, the controller 160 transmits a response message to the glasses device to perform a connection operation between the interface unit 150 and the glasses device according to a communication protocol defined between the glasses device. do.

For convenience of description, it is assumed that the interface unit 150 includes a Bluetooth communication module and performs a connection operation according to a Bluetooth communication protocol and a Bluetooth communication module provided in the spectacle device.

In detail, the glasses device broadcasts an Inquiry Message to perform a pairing operation, and searches for a display device within a range in which Bluetooth communication is possible. When the query message is received, the controller 160 controls the interface unit 150 to transmit an extended Inquiry Response (EIR) thereto. Here, the response message may include a Bluetooth address, a device name, a COD (Class of Device), and clock information.

On the other hand, the spectacle device receiving the response message transmits the transmission packet including the Bluetooth address, the device type (Type), and the like to the display device 100. When the corresponding transmission packet is received through the interface unit 150, the controller 160 may control the interface unit 150 to transmit / receive a PIN code with the glasses device, and perform a pairing operation with the glasses device. have. Here, the controller 160 automatically registers the display device by inputting the pin code even when the user does not directly input the pin code, thereby performing the pairing operation. However, the present invention is not limited to this, and it is also possible to perform the pairing process by a method in which the user directly inputs the pin code of the display device.

As such, when the query message is received from the spectacle apparatus, the controller 160 transmits a response message corresponding thereto to perform a connection operation so that the interface unit 150 and the spectacle apparatus can communicate. At this time, the controller 160 may control the audio data transmitter 170 to transmit the audio data modulated by the RF method to the eyeglasses when the query message is received from the eyeglasses.

On the other hand, the controller 160 controls to display the received information in the form of a UI (User Interface) on the screen (display unit) of the output unit 130, when the information indicating whether the audio data is received from the spectacle device is received. . Here, the information indicating whether the audio data is received is recorded in the reserve area in the transport packet transmitted during the connection operation between the interface unit 150 and the spectacles. The eyeglasses having received the response message transmit the transmission packet including the Bluetooth address, the device type, and the like to the display apparatus 100 as described above. That is, the spectacle apparatus may record information indicating whether audio data is received in the reserve area of the corresponding transport packet and transmit the information to the display apparatus 100.

Accordingly, the controller 160 may determine whether audio data is being received from the spectacle device by referring to the information recorded in the reserve area in the transport packet. For example, the controller 160 determines that audio data is being received by the spectacle device when the bit value '1' is read from the reserve area, and when the bit value '0' is read out from the reserve area, the control unit 160 outputs the audio data. It can be determined that data is not being received.

However, this is merely an example, and information indicating whether audio data is received may be recorded in various forms according to a predetermined method between the spectacle apparatus and the eyeglass apparatus. That is, the controller 160 may determine that audio data is not received from the spectacle device if no bit value is recorded in the reserve area in the transport packet.

The controller 160 may control the output unit 130 to display information indicating whether audio data is received on a screen (display unit) in a UI form. In this case, the controller 160 may display information on the connection state of the interface unit 150 together on the UI. In detail, the controller 160 displays at least one of a message in which audio data is normally received from the glasses device and a message indicating that the interface unit 150 is normally connected to the glasses device in the form of an OSD (display unit). ) Can be displayed. Accordingly, information about an operation state of the spectacle device may be provided to the user.

Meanwhile, the controller 160 may control the interface unit 150 to transmit one of the synchronization signals corresponding to each of the plurality of contents to the glasses device having completed the connection operation.

Here, the synchronization signal transmitted to the spectacles device may be set by default. For example, it is assumed that an image frame of the first content and an image frame of the second content are alternately displayed. In this case, the synchronization signal corresponding to the first content among the synchronization signal corresponding to the first content and the synchronization signal corresponding to the second content may be set to be transmitted to the eyeglass apparatus.

When the request message requesting the transmission of another synchronization signal is received from the spectacle device, the controller 160 may control the interface unit 150 to transmit another synchronization signal. In this case, the controller 160 may modulate audio data related to each content into different frequency signals, and transmit audio data related to content corresponding to other synchronization signals using a new frequency band.

Meanwhile, in the above-described embodiment, the synchronization signal set as a default is transmitted to the spectacle device in which the connection operation is completed, but this is merely an example.

That is, the controller 160 may control the interface unit 150 to transmit the same or different synchronization signals to different eyeglasses based on the information obtained through the pairing operation. In addition, the interface unit 150 may transmit the same synchronization signal to some eyeglasses. For example, the interface unit 150 may transmit a synchronization signal corresponding to the content 1 to the glasses device 1, a synchronization signal corresponding to the content 2 to the glasses device 2, and a synchronization signal corresponding to the content 1 to the glasses device 3.

In addition, the controller 160 may control the interface unit 150 to generate a synchronization signal corresponding to the display timing of each content as one transport packet according to the Bluetooth communication standard. That is, the interface unit 150 synchronizes the display timing of the first content to open / off the shutter glass of the spectacles device, and synchronizes the display of the second content to open / off the shutter glasses of the spectacles device. Time information, ..., and one transmission packet including all the time information for opening / off the shutter glass of the spectacle device in synchronization with the display timing of the n-th content.

In this case, the interface unit 150 may generate a transport packet by matching the information on the spectacles with the display timing of each content. For example, the interface unit 150 may match information about different glasses devices for each content in the order in which the image frames of the content are arranged. That is, when two contents are provided in the multi-view mode (second mode), the image frames of the first, third, ..., n-th arranged image frames match the information about the spectacle device 1, The image frames of the contents arranged in the fourth, fourth, ..., n + 1th may match the information about the spectacle device 2 (where n is odd). In addition, the interface unit 150 may transmit a transmission packet generated to include a synchronization signal for each of the plurality of contents to the spectacles.

Watching on glasses Content  Switching embodiment

Hereinafter, a system and a method of switching content currently being viewed by an eyeglass device to view other content will be described.

As illustrated in FIG. 57, when a switching command is input through an input unit 210 provided in the spectacles 200, the display apparatus 100 and the spectacles 200 perform a content switching operation. . Accordingly, a user wearing the spectacles 200 may view content 3, content 4, and content 1 sequentially. Subsequently, when a selection command is input through the input unit 210, the spectacle apparatus 200 opens both the left shutter glass and the right shutter glass in synchronization with the content 1 viewed by the user at the time when the selection command is input. Accordingly, the user can select and view the content 1.

Hereinafter, the display apparatus 100 and the spectacles 200 according to various embodiments of the present disclosure performing the above functions will be described in detail.

58 is a block diagram illustrating a configuration of a display apparatus according to an exemplary embodiment. Referring to FIG. 58, the display apparatus 100 includes a plurality of receivers 110-1, 110-2,..., 110-n, and a plurality of signal processors 120-1, 120-2,. n), an output unit 130, a synchronization signal generator 140, an interface unit 150, and a controller 160.

A plurality of receivers 110-1, 110-2, ..., 110-n, a plurality of signal processors 120-1, 120-2, ..., 120-n, output unit 130, synchronization The signal generation unit 140, the interface unit 150, and the control unit 160 are the same as described above except for contents described separately below, and overlapping descriptions thereof will be omitted.

The interface unit 150 communicates with the spectacles. In this case, the interface unit 150 may communicate with the spectacle apparatus according to various wireless methods, transmit a synchronization signal to the spectacle apparatus, and receive a content switching command from the spectacle apparatus.

Meanwhile, the interface unit 150 transmits / receives a Bluetooth device address, a pin code, and the like with the glasses device, and performs pairing according to a Bluetooth communication method. When the pairing is completed, the interface unit 150 may transmit a synchronization signal corresponding to one of the plurality of contents to the glasses device based on the information obtained through the paying.

In addition, when pairing with a plurality of eyeglasses is completed, the interface unit 150 may transmit the same or different synchronization signals to different eyeglasses based on the information obtained through the paying. In addition, the interface unit 150 may transmit the same synchronization signal to some eyeglasses. For example, the interface unit 150 may transmit a synchronization signal corresponding to the content 1 to the glasses device 1, a synchronization signal corresponding to the content 2 to the glasses device 2, and a synchronization signal corresponding to the content 1 to the glasses device 3.

Although the above-described embodiment has been described as the interface unit 150 and the spectacle device performing communication according to the Bluetooth communication method, this is only an example. That is, in addition to the Bluetooth method, it is possible to use a communication method such as infrared communication, Zigbee, etc., and to perform communication according to various wireless communication methods capable of transmitting and receiving signals by forming a communication channel in other local areas. .

When the content switching command is received from the spectacles device, the controller 160 performs a switching operation of sequentially switching the contents corresponding to the spectacles to other contents among the plurality of contents.

In detail, when a content change command is received, the controller 160 controls the output unit 130 to change the arrangement pattern of the image frames of the respective contents, and thus the image of the other contents at the position of the image frame of the content corresponding to the eyeglasses device. You can process the frame to be located.

For example, it is assumed that the output unit 130 displays alternately arranged image frames of the first to third contents, and that a synchronization signal corresponding to the display timing of the first contents is being transmitted to the spectacle apparatus. . When the switching command is received from the glasses device synchronized to the first content, the controller 160 sequentially arranges the image frame of the second content and the image frame of the third content at the image frame position of the first content. ) Can be controlled. In this case, the controller 160 may control the interface unit 150 to continuously transmit the synchronization signal for the display timing of the first content before the arrangement pattern of the image frame is changed to the glasses device. Accordingly, the user wearing the spectacles can view all the contents sequentially.

On the other hand, when the content switching command is received, the controller 160 controls the interface unit 150 to transmit a synchronization signal corresponding to other contents among the plurality of contents to the glasses apparatus, so that the glasses apparatus is connected to the other contents among the plurality of contents. Can be processed to be synchronized.

For example, when the interface unit 150 is implemented as a Bluetooth communication module, the control unit 160 sequentially transmits each of the transport packets including information on the display timing of other contents to the eyeglasses when a content switching command is received. The interface unit 150 may be controlled to control the interface unit 150. The spectacle apparatus opens / offs the shutter glass of the spectacle apparatus based on the time information included in the sequentially received transmission packet. Accordingly, the user can sequentially watch all the contents.

If the selection command is received through the interface unit 150 while the contents corresponding to the spectacles are sequentially switched to other contents among the plurality of contents, the controller 160 displays the contents at the time when the selection command is received through the spectacles. The switching operation is terminated to allow viewing.

In detail, when the selection command is input from the spectacle device while changing the arrangement pattern of the content or the synchronization signal, the controller 160 sequentially changes the content synchronized to the spectacle device. The spectacles may be synchronized based on the arrangement pattern of the content or the synchronization signal.

That is, the controller 160 ends the change of the arrangement pattern of the content at the time when the selection command is input, and alternately displays a plurality of contents based on the arrangement pattern of the rearranged content. Alternatively, the controller 160 transmits a synchronization signal for the content displayed at the time when the selection command is input to the spectacles. Accordingly, the spectacle device is synchronized with the content displayed at the time when the selection command is input, and the user can watch the desired content according to the selection command.

Meanwhile, the switching operation may be performed while the content switching command is received from the glasses device. That is, the controller 160 may perform the content switching operation at the time when the content switching command is received, and then control to stop the content switching operation when the reception of the content switching command is terminated.

Meanwhile, in the above-described embodiment, the display apparatus 100 generates synchronization signals corresponding to the display timing of the contents, and transmits them to the glasses apparatus 200. However, this is merely an example.

That is, the controller 160 may control the interface unit 150 to generate a synchronization signal corresponding to the display timing of each content as one transport packet according to the Bluetooth communication standard. That is, the interface unit 150 synchronizes the display timing of the first content to open / off the shutter glass of the spectacles device, and synchronizes the display of the second content to open / off the shutter glasses of the spectacles device. Time information, ..., and one transmission packet including all the time information for opening / off the shutter glass of the spectacle device in synchronization with the display timing of the n-th content.

In this case, the interface unit 150 may generate a transport packet by matching the information on the spectacles with the display timing of each content. For example, the interface unit 150 may match information about different glasses devices for each content in the order in which the image frames of the content are arranged. That is, when two contents are provided in the multi-view mode (second mode), the image frames of the first, third, ..., n-th arranged image frames match the information about the spectacle device 1, The image frames of the contents arranged in the fourth, fourth, ..., n + 1th may match the information about the spectacle device 2 (where n is odd). In addition, the interface unit 150 may transmit a transmission packet generated to include a synchronization signal for each of the plurality of contents to the spectacles. The spectacle device may open / off the shutter glass by using a synchronization signal including its spectacle device information among the synchronization signals for each of the plurality of contents.

59 is a block diagram illustrating a configuration of an eyeglass device according to an embodiment of the present invention. In particular, the spectacle apparatus 200 of FIG. 59 is interlocked with the display apparatus 100 that alternately displays a plurality of contents in image frame units, and includes an input unit 210, a controller 220, a shutter glass driver 230, The interface unit 240 includes a first shutter glass unit 250 and a second shutter glass unit 260.

Since the above components perform the functions of the above-described corresponding configurations except for the contents separately described below, overlapping descriptions will be omitted.

The interface unit 240 performs communication from the display device. For example, the interface unit 240 may be implemented as a Bluetooth communication module to communicate with the display apparatus 100 to receive a synchronization signal and transmit a content switching command to the display apparatus 100.

As described above, the synchronization signal may be received in the form of a transmission packet according to the Bluetooth communication standard, and synchronized to the display timing of the content, the first shutter glass unit 250 and the second shutter glass unit ( 260 may include time information for opening or turning off.

The input unit 210 receives a switching command for initiating a switching mode. To this end, the input unit 210 may include a switching button for receiving a switching command, and the switching button may be implemented as a touch sensor or an operation button.

In addition, the input unit 210 receives a selection command for selecting one content while the switching mode is performed and the contents are sequentially switched. The input unit 210 may also receive a selection command through a switching button that receives a switching command. For example, the input unit 210 may be implemented by receiving a switching command while the switching button is being touched, and receiving a selection command at the time when the touch state ends when the touch state of the switching button ends. On the other hand, the input unit 210 may include a separate selection button implemented as a touch sensor or an operation button.

When the switching mode is started, the controller 220 receives a synchronization signal corresponding to other contents that can be viewed from among a plurality of contents, and sequentially opens the opening timings of the first shutter glass unit 250 and the second shutter glass unit 260. Control to change to To this end, when the switching mode is started, the controller 220 controls the interface unit 240 so that a content switching command for requesting a synchronization signal corresponding to another content is transmitted to the display apparatus 100.

The display apparatus 100 receiving the content switching command sequentially transmits each of the transport packets including information on the display timing of other contents that can be viewed in addition to the contents currently viewed by the user to the eyeglass apparatus 200. The controller 220 may sequentially receive a synchronization signal corresponding to other contents, and control the shutter glass driver 230 to sequentially generate a driving signal based on the synchronization signal corresponding to each content. Accordingly, the first shutter glass unit 250 and the second shutter glass unit 260 are opened whenever an image frame of each content is displayed. As described above, since the spectacle device is sequentially synchronized with each content, the user can view all the contents sequentially.

On the other hand, if the selection command is input through the input unit 210 while the switching mode is being performed, the controller 220 ends the switching mode, and according to the display timing of the viewable content at the timing at which the selection command is input, the first shutter glass unit The shutter glass driver 230 is controlled to fix the open timing of the 250 and the second shutter glass unit 260.

That is, when the selection command is input, the controller 220 controls the interface unit 240 to transmit a command for requesting the stop of the content switching operation to the display apparatus 100. The controller 220 controls the shutter glass driver 230 to generate a driving signal based on the synchronization signal received from the display apparatus 100 at the time when the selection command is input. Accordingly, a user who has sequentially watched a plurality of contents can view one selected content at a time when a selection command is input.

Meanwhile, as described above, the switching command and the selection command may be input through one switching button. In this case, the controller 220 performs the switching mode while the switching button is being touched, and when the touch state of the switching button ends, terminates the switching mode and adjusts the display timing of the viewable content when the touch state ends. The shutter glass driver 230 may be controlled to fix the open timing of the first shutter glass unit 250 and the second shutter glass unit 260.

That is, when the switching mode ends, the controller 220 controls the shutter glass driver 230 to generate a driving signal based on the synchronization signal received at the end of the switching mode. Accordingly, a user who has sequentially watched a plurality of contents can view one selected content when the touch state of the switching button ends.

Meanwhile, in the above-described embodiment, the display apparatus 100 generates synchronization signals corresponding to the display timing of the contents, and transmits them to the glasses apparatus 200. However, this is merely an example. That is, the display apparatus 100 may generate a synchronization signal corresponding to the display timing of each content as one transport packet according to the Bluetooth communication standard and transmit the synchronization signal to the spectacles device.

When the synchronization signal is received, the controller 220 may check a display timing corresponding to the glasses device information and open or turn off the shutter glass according to the confirmed display timing. When the switching command is input, the controller 220 may control the shutter glass driver 230 to sequentially generate a driving signal based on a synchronization signal corresponding to each content included in the transport packet. Accordingly, the first shutter glass unit 250 and the second shutter glass unit 260 are sequentially opened whenever an image frame of each content is displayed. The controller 220 may control to generate a driving signal based on a synchronization signal at a time when a selection command is input, and select one of contents to be sequentially converted.

In addition, in the above-described embodiment, the display apparatus and the eyeglass apparatus communicate with each other according to various wireless communication methods capable of transmitting and receiving signals by forming a communication channel at a short distance, but this is merely an example. That is, the display device provides an IR (Infra Red) synchronization signal having a different frequency to the glasses device, the glasses device receives a synchronization signal having a specific frequency, and open or off the shutter glass in accordance with the display timing of the corresponding content Of course you can.

600 is a flowchart illustrating a content selection method according to an embodiment of the present invention. Particularly, in the present embodiment, a content selection method of a spectacle device interoperating with a display device that alternately displays a plurality of contents in image frame units will be described.

Thereafter, when the switching mode is started (S6020-Y), the opening timings of the first and second shutter glass units are sequentially changed (S6030).

In detail, when the switching mode is started, a content switching command for requesting a synchronization signal corresponding to other content may be transmitted to the display apparatus. When the switching mode is started, a synchronization signal corresponding to other contents that can be viewed from among a plurality of contents is received, and the opening timings of the first and second shutter glass units are sequentially changed.

That is, based on the synchronization signal corresponding to other content, the image frame of each content is opened every time it is displayed, and all contents are sequentially provided to the user. Here, the switching mode may be started when a switching command is input through a switching button provided in the spectacle device.

When the switching mode is terminated (S6040-Y), it is synchronized to the selected content (S6050). In detail, when one of the contents to be sequentially switched is selected and the switching mode is terminated, the opening timing of the first and second shutter glasses may be maintained so that the selected contents can be viewed. To this end, the selection command is input while the switching mode is being performed, the switching mode is terminated, and the opening timing of the first and second shutter glass units is fixed according to the display timing of the viewable content at the timing at which the selection command is input.

That is, the spectacle device may be synchronized with the selected content based on the synchronization signal corresponding to the display timing of the content provided to the user when the selection command is input. Accordingly, a user who has sequentially watched a plurality of contents can view one selected content at a time when a selection command is input. In this case, the switching mode is performed while the switching button is being touched, and may end when the touch state of the switching button is released.

61 is a flowchart illustrating a content switching method according to an embodiment of the present invention. In particular, the present embodiment describes a method of switching content in the display device.

In this case, video data may be separated from a plurality of contents, and processing such as decoding, scaling, frame rate conversion, and the like may be performed on the video data. Since the detailed operation has been described above, redundant description will be omitted.

Thereafter, the synchronization signal is transmitted (S6120). Specifically, according to the display timing of each content, a synchronization signal for synchronizing the spectacles device corresponding to each content is transmitted.

When the content switching command is received from the spectacle device (S6130-Y), the content switching operation is performed (S6140). In detail, when a content switching command is received, a switching operation is performed in which the content corresponding to the eyeglasses device switches to another content among the plurality of contents.

Specifically, when a content change command is received, the arrangement pattern of the content may be changed to process the frame of other content to be positioned at the frame position of the content corresponding to the spectacles. On the other hand, when a content switching command is received, a synchronization signal corresponding to other content among a plurality of contents may be transmitted to the eyeglass apparatus so that the glasses apparatus may be synchronized with other content among the plurality of contents. Each of these embodiments has been described above, and thus redundant description is omitted.

When the switching operation is completed (S6150-Y), the switching operation is terminated (S6160). That is, when one of the plurality of contents is selected, the switching operation ends. Specifically, when a selection command is received from the spectacle apparatus while the contents corresponding to the spectacle apparatus are sequentially switched to other contents among the plurality of contents, the switching operation is performed so that the content at the time when the selection command is received can be viewed through the spectacle apparatus. Quit.

In this case, the switching operation may be performed while the switching command is received from the spectacles device. That is, while performing the content switching operation at the time when the switching command is received, it may be controlled to stop the content switching operation when the reception of the switching command is terminated.
