METHODS OF CONSTRUCTING SINGLE SCREEN AND APPARATUSES FOR USING THE SAME}

The present invention relates to a single screen configuration method and an apparatus using the method, and more particularly, to an image reproduction method.

N screen means the common contents of various devices equipped with common operating system.

Means available services. For example, you can buy a particular movie, music, or game from the smartphone app store, then come home and watch the same content on your TV or PC. There should be no additional costs or technical obstacles. The target content is not limited to entertainment contents such as movies, music, and games, but it can be shared from personal information such as address book and e-mail to document work. .

N screen means literally providing content through several (N) screens (screens). For example, if an avatar movie VOD is purchased and the avatar can be viewed on various devices such as a TV, a tablet, a smartphone, a PC, and the like, it may be a kind of N screen. After the advent of the popularization of smart devices, the biggest reason for the recent rise of N-screens is the rapid spread of smart devices. Smart devices such as smartphones, tablets, and smart TVs are growing in earnest. In fact, the forecasts of major market research institutes such as Display Search and Gartner are predicting steep growth of 30 ~ 80% per year over the next three years.

The proliferation of smart devices is a significant basis for N-screens in terms of connectivity and processing performance between devices. Currently spreading smart devices are basically equipped with an operating system (Operating System), operation and voice recognition module, transmission standards, etc. can use the service linked with other smart devices.

It is an object of the present invention to provide a method for constructing a single screen.

Still another object of the present invention is to provide an apparatus for performing the method for constructing a single screen.

The single screen configuration method according to an aspect of the present invention for achieving the above object of the present invention may include the step of dividing the received multimedia information and transmitting the divided multimedia information to the slave terminal.

As described above, the method for configuring a single screen according to an embodiment of the present invention may divide and output multimedia information based on a master terminal and a slave terminal connected to the master terminal.

Referring to FIG. 3, after being stored or streamed in one terminal of the master terminal A or the slave terminals B to L, the image is divided in the master terminal A according to the location information of each terminal. The divided image may be transmitted to each slave terminal B to L. At this time, in order to match the reproduction synchronization of each divided video, the video synchronization information may be transmitted from the master terminal A to each of the slave terminals B to L, and the transmitted synchronization information may be controlled. Each terminal receiving the divided image outputs the corresponding image using the synchronization information.

The master terminal A may control fast forward, rewind, pause, play, and the like related to video playback. In addition, the master terminal A may output sound data using a speaker of the terminal. If the sound data is 2.1 channels, a total of three terminals can output 2.1 channel sound data. That is, two terminals output one channel each and the other terminal outputs the remaining one channel. If the sound data is 5.1 channels, a total of six terminals can output 5.1 channel sound data. In addition, the master terminal A may adjust the volume of the sound data. That is, the sound module existing in the master terminal A and the slave terminals B to L can be assigned to one channel to reproduce sound.

That is, the master terminal A may identify the position information of the slave terminals B to L using a communication network or GPS and adjust the positions of the master terminal A and the slave terminals B to L on a single screen. The image information transmitted to the master terminal A or the preprocessing stage existing in the previous stage of the single screen is the physical position from the master terminal A based on the position information of the master terminal A and the slave terminals B to L. The divided images may be output using the same or the like.

As described above, the communication unit 400 may use a local area network technology such as Wi-Fi and Bluetooth, or a mobile phone communication network technology such as multiband GSM, CDMA, and WCDMA. The master terminal can receive multimedia information using the communication unit 400 and can also exchange information with the slave terminal.

The image divider 405 may divide the multimedia information provided through the communication unit 400 into a plurality of images so that the multimedia information can be reproduced by the master terminal and the slave terminal connected to the master terminal.

The image output unit 410 may output image data of the multimedia data transmitted through the communication unit 400 through the display device.

The sound output unit 415 may output sound data among the multimedia data transmitted through the communication unit 400 through the speaker.

The location controller 420 may calculate and control location information of a slave terminal connected to the master terminal.

The synchronization unit 425 may synchronize the multimedia information output to the slave terminal connected to the master terminal.

The multimedia controller 430 may control the multimedia content being played in the master terminal and the slave terminal connected to the master terminal through fast forward, rewind, pause, and play or control sound information values.

5 is a conceptual diagram illustrating a slave terminal according to an embodiment of the present invention.

Referring to FIG. 5, the slave terminal may include a communication unit 500, an image output unit 510, an audio output unit 520, and a synchronization unit 530.

The communication unit 500 may provide multimedia information provided from the master terminal, and the image output unit 510 may reproduce the image information provided from the master terminal. The sound output unit 520 may output sound information provided from the master terminal. The synchronization unit 530 may receive synchronization information from the master terminal and synchronize outputs with the master terminal and other slave terminals.

As described above, when the master terminal and the slave terminal are only devices classified according to roles, and functions may be performed in the same manner, the master terminal disclosed in FIG. 4 may be a slave terminal.

6 is a flowchart illustrating a multimedia playback method according to another embodiment of the present invention.

Referring to FIG. 6, multimedia information is received (step S600).

Multimedia information may be provided through a communication network. The multimedia information may be transmitted to the master terminal or in some cases through a communication network of the slave terminal. The multimedia information may not be directly transmitted to the terminal but may also be transmitted through a reception device existing in the previous preprocessing stage.

The multimedia information is divided (step S610).

The multimedia information transmitted to the master terminal or the preprocessor may be divided into information for transmission to the master terminal and the slave terminal.

For example, in order to divide the screen information, network state and connection state information of the master terminal and the slave terminal may be determined first. For example, when one master terminal and three slave terminals are connected, one image may be divided into four screens. In addition, in the case of sound information, if there are three channels, the sound channel may be divided and transmitted differently based on the number of terminals currently available.

The divided multimedia information is transmitted to the slave terminal (step S620).

The master terminal can transmit the divided multimedia information to the slave terminal. The master terminal and the slave terminals connected to the master terminal may divide and reproduce one multimedia image or sound into a plurality of image and audio devices.

The divided multimedia information may be synchronized and reproduced and output according to a synchronization signal transmitted by the master terminal.
