As shown in fig. 5b, the application layer 2912 contains various applications that may be executed on the display device 200. Applications may include, but are not limited to, one or more applications such as: live television applications, video on demand applications, media center applications, application centers, gaming applications, etc.

Live television applications can provide live television through different signal sources. For example, a live television application may provide television signals using inputs from cable television, radio broadcast, satellite services, or other types of live television services. And, the live television application may display video of the live television signal on the display device 200.

Video on demand applications may provide video from different storage sources. Unlike live television applications, video-on-demand provides video displays from some storage sources. For example, video-on-demand may come from the server side of cloud storage, from a local hard disk storage containing stored video programs.

An application center may be provided to store various applications. The application may be a game, an application, or some other application associated with a computer system or other device but which may be run in a smart television. The application center may obtain these applications from different sources, store them in local storage, and then be run on the display device 200.

A schematic diagram of a user interface in the display device 200 in an embodiment of the present application is schematically shown in fig. 6. As shown in fig. 6, the user interface includes a plurality of selectable options. The user interface can display a plurality of option pictures in the form of icons or characters, and the plurality of option pictures can respectively correspond to a plurality of application programs. The program may be a system program built in an operating system such as "media center", "Hi music", "setup", or the like. The program may also be a third party application downloaded and installed by the user, such as "WeChat", "QQ music", etc.

In the user interface, at least one option is designated to graphically and/or literally represent a music playing application. Since third party applications typically do not have the capability to play music in the terminal, in embodiments of the present application, a music playing application, such as "Hi music" may be built into the operating system level. When the option picture corresponding to the music playing application is selected, the music playing application can be started, and meanwhile, a program interface special for the music playing application is displayed in the user interface. For example, when Hi music is selected and opened, a program interface corresponding to the Hi music may be presented in the user interface. As shown in fig. 7, a screen such as a dynamic view or text representing a music playing function is shown.

In practical application, the selection of the options refers to clicking the option screen by a series of operations on the remote controller. In the user interface, one of the option screens is selected and can be presented by the selected tab. The selection of the option screen can be indicated by a display mode such as a selection box, a highlighted text, a magnified menu and a lower menu. For example, a selection box marked as a rectangular structure is selected. The user adjusts the position of the selection frame through the keys of up, down, left and right on the remote controller, after the selection frame selects the application program icon corresponding to Hi music, the user can start the Hi music application by clicking the key of ok on the remote controller, and at this time, the option screen representing Hi music is selected.

The user may perform a series of interactive operations, i.e., user inputs, through the user interface. The user input includes a launch instruction indicating that the music playing application is selected. In practice, the user input may be a remote control based interactive operation. For example, by operating the remote controller, after the selection box on the user interface selects the application icon corresponding to "Hi music", the "Hi music" application may be started by pressing the "ok" button on the remote controller. That is, the user inputs a start instruction indicating that the music playing application is selected. The user input may also be based on interactive operations of a voice system, a gesture system, etc. For example, the user may input the voice "open Hi music" through the voice system, at which point the operating system may automatically launch the "Hi music" application. That is, the user input is also a start instruction indicating that the music playing application is selected.

For the interactive operation corresponding to the start instruction, the controller 210 may control the display to present the screen of the music playing application, as shown in fig. 7. Meanwhile, the controller 210 may also control the sound output device of the bluetooth module 132 to establish a wireless connection, or set the wireless transmission mode of the bluetooth module 132 to a receiving mode, so as to receive the audio signal sent by the sound output device, and convert the audio signal into sound through a speaker, so as to play music in the terminal.

The bluetooth module 132 may establish a wireless connection with the sound output device or the sound input device, i.e., the wireless transmission mode of the bluetooth module includes a transmitting mode and a receiving mode. In which the transmission mode means that the display device 200 functions as a signal source or a transmitter of a signal or data in this mode. The display device 200 may send the generated signal to other devices in a wireless manner, so as to utilize hardware of the other devices to realize the display of the specific audio/video resource. The receiving mode means that in this mode, the display device 200 may receive signals or data from other devices (terminals) through the bluetooth module to display audio and video resources using hardware on the display device 200.

For example, the bluetooth A2DP mode at the display device 200 includes "source (transmission mode)" and "sink (reception mode)". If the terminal is wirelessly connected to the display device through bluetooth connection, when receiving a start command input by a user, the terminal controls the A2DP mode of the display device 200, and sets the bluetooth A2DP mode to sink mode.

In order to play music in the terminal at the display device 200, the controller 210 may determine the user input after receiving the user input. If the user input is a start instruction, the controller 210 may start the music playing application and set the transmission mode of the bluetooth module to the reception mode. After the bluetooth module transmission mode of the display apparatus 200 is set to the reception mode, the display apparatus 200 may receive the audio signal transmitted from the terminal in real time and play the received audio signal through the speaker.

It can be seen that after the wireless connection between the display device and the terminal is completed, the wireless transmission mode may be set to the reception mode according to a start instruction input by the user. At this time, the display device 200 may be regarded as a wireless speaker connected to the terminal, and as the terminal plays the audio resource, the display device 200 may play the music corresponding to the audio resource. Therefore, the entire music playing process does not require transferring the audio source file between the terminal and the display device 200. Meanwhile, the display device 200 directly receives the audio signal through the bluetooth module, and the playing program such as decoding of the music file still runs in the terminal, so that the display device 200 provided by the application can play all music in the terminal without installing the same music playing application program with the terminal.

For the above-mentioned music playing process, in practical application, a wireless connection may be established between the terminal and the display device 200. For example, the setup related program may be initiated through a "setup" options screen in the user interface. After the "setup" procedure is started, a screen related to the setup may be displayed on the user interface, and the user may send a control instruction through the control device 100, select "bluetooth" - "bluetooth switch" in the user interface, and enable the bluetooth module of the display device. Then sequentially selecting 'Bluetooth' - 'Bluetooth connection mode' - 'mobile phone' in the user interface to complete wireless connection between the terminal and the display device 200.

After the wireless connection is established between the terminal and the display device 200, the user can play music in the terminal through the operation on the terminal. Since the transmission mode of the display apparatus 200 is the reception mode, when the terminal plays music, an audio signal is generated and transmitted to the display apparatus 200 through a wireless connection manner such as bluetooth, so that the audio signal is converted into music through a speaker of the display apparatus 200. During the playing of music, a screen containing the playing process, for example, "Hi music in use", etc., may also be presented in the user interface.

In some embodiments of the present application, the user interface further includes a prompt screen, where the prompt screen displays the prompt information through graphics and/or text. For example, after the controller 210 selects to execute the wireless connection setting program, the prompt screen may display the execution result of the wireless connection setting program. That is, after selecting the option screen corresponding to the execution "bluetooth switch", the prompt screen may display "bluetooth on" or "bluetooth off" in the form of a pop-up window.

The prompt screen may also display the execution progress of the application program, for example, in the process of the controller 210 executing the wireless connection setting program corresponding to the "connect to phone" option screen, a prompt screen of "… please be later in connect to phone" is displayed in the user interface, and after the connect to phone is completed, a prompt screen of "connected××phone" is displayed.

When the user selects the icon corresponding to the music playing application on the user interface, the application program is started, so if the user input is a start instruction, as shown in fig. 9, the controller is further configured to execute the following program steps: s21: and judging whether the Bluetooth module has established wireless connection with the sound output device.

For example, the user interface includes an icon "Hi music" indicating a music playing application, and when the user manipulates the selected icon, the user may click "ok" to open the application, at which point the user interface generates an instruction for starting the music playing application, and the controller 210 may acquire the starting instruction. It may be detected whether the aforementioned bluetooth module has established a wireless connection with the sound output device, i.e. whether the display apparatus has made a matching connection with the terminal, and whether the transmission mode of the display apparatus 200 is sink mode in the current matching connection form.

S22: and if the Bluetooth module is in wireless connection with the sound output device, acquiring an audio signal of the sound output device through the Bluetooth module.

In practical applications, if the display device 200 establishes a connection with the terminal in the receiving mode, the display device 200 may be regarded as a bluetooth speaker connected to the terminal, and the bluetooth speaker may replace a speaker on the terminal to play sound. When a user selects to play music on the terminal, the terminal decodes the audio file, generates an audio signal, and transmits the generated audio signal through bluetooth.

S23: and controlling a display device loudspeaker to play the audio signal.

The display device 200 receives the corresponding audio signal through the bluetooth module and forwards the audio signal to a speaker of the display device, playing the audio signal as a specific music or sound signal.

S24: and if the Bluetooth module does not establish wireless connection with the sound output device, controlling the display to display a connection prompt picture.

In practical applications, if the bluetooth module of the display apparatus 200 does not establish a wireless connection with any terminal, the display apparatus 200 is not able to play music in the terminal, and thus a connection prompt screen may be displayed in the user interface so that the user connects the terminal with the display apparatus 200. For example, after the user interface selects the "Hi music" application icon, if the controller 210 does not detect that a connection has been established between the bluetooth module and the terminal, a screen with a prompting function such as "please connect with a mobile phone" is displayed in a prompting screen form in the user interface, and after the user selects and determines, the user interface is jumped to an option screen corresponding to "bluetooth connection mode-connect with the mobile phone".

It can be seen that, in this embodiment, since the display device 200 directly receives the audio signal through the bluetooth connection and the music is played by the terminal, it is not necessary to install the same music playing software in the display device 200 and the terminal, and it is not necessary to copy the audio file into the display device 200, and the display device 200 can play all the music in the terminal.

The display device 200 may receive an audio signal of the terminal if the bluetooth module has established a wireless connection with the terminal. However, since the terminal and the display device 200 are two different devices, a user needs to perform a play operation at the terminal when playing music in the terminal, thereby generating an audio signal, and then transmitting the generated audio signal through bluetooth. Thus, in some embodiments, as shown in fig. 10, after the bluetooth module establishes a wireless connection with the terminal, the controller is further configured to:

s221: and monitoring the audio stream input state of the sound output device through the Bluetooth module.

The controller 210 may monitor whether the bluetooth module receives the audio signal, and determine an audio stream input state of the terminal; or directly determining whether the terminal plays music by acquiring the operation action in the terminal. If it is determined that the audio signal from the terminal is received in the Bluetooth module, the terminal is determined to play the audio file.

S222: and if the sound output device plays the audio file, acquiring an audio signal sent by the terminal.

After the terminal is determined to play the audio file, an audio signal sent by the terminal can be obtained, namely, the audio stream sent by the terminal is received through the Bluetooth module. After receiving the audio stream, the bluetooth module can sort and forward the audio stream to a sound playing circuit of the display device for transmission to a speaker of the display device.

S223: and starting a loudspeaker of the display device to play the audio signal.

After the audio signal sent by the terminal is obtained, the controller 210 also controls the speaker to start to operate, and converts an electrical signal corresponding to the audio signal into a sound signal. So that the speaker can play out music corresponding to the audio file in the terminal while continuously inputting the audio stream.

Since playing music in the terminal through the display device 200 only calls the speaker on the display device to operate, and the display is not involved in the music playing process at this time, in order to save energy and reduce equipment loss, the display may be turned off and only the speaker is used to play music. Thus, in some embodiments, as shown in fig. 11, the controller is further configured to:

s231: the control display displays a close screen prompt screen and starts a timer.

After the display device 200 acquires the audio signal transmitted from the terminal through the bluetooth module, the audio signal may be delivered to the speaker so that the speaker can play the received audio signal. Meanwhile, after it is determined that the speaker has started playing the audio signal, a prompt screen to turn off the screen (display) may also be displayed in the user interface. For example, a prompt screen displayed in the user interface carries prompt text such as "about to close screen".

In practical applications, since the user may perform other operations in the user interface when playing the music in the terminal by using the display device 200, after the display device plays the music, the screen may be turned off after a preset time is delayed, that is, a timer is started in the control program, and after reaching the preset screen closing time, the timer may trigger the controller to perform a corresponding operation. The preset off-screen time can be adjusted according to the display equipment without signals, and is generally 5-10s. As shown in fig. 12, a countdown screen, for example, "screen off countdown", may also be displayed in the prompt screen of the screen off: x s ", etc.

S232: and acquiring an instruction which is input by a user and is used for canceling the screen closing before the timer reaches the preset screen closing time.

While the screen-closing prompt screen is displayed, a part of options can be added in the prompt screen, so that a user can select whether to close the screen or not through operation. For example, in "off-screen countdown: a button control can be displayed below the x s' and provided with prompt information of cancelling the screen closing. When the user selects the "cancel screen" button control by operation, a cancel screen command may be generated.

S233: and if the instruction for canceling the screen closing is acquired before the timer reaches the preset screen closing time, controlling a display to display a picture corresponding to the music playing application.

Before the timer reaches the preset screen closing time and before the screen closing countdown reaches 0s, if the user selects the screen closing cancellation command, the controller receives the screen closing cancellation command, and at the moment, the controller cancels the screen closing countdown and does not close the screen any more. At this time, the original user interface, i.e., a screen before entering "Hi music", or a music play application prompt screen may be displayed on the screen. The music playing application prompt screen can contain graphics, dynamic video and the like related to music playing so as to play a role of screen protection.

S234: and if the instruction for canceling the screen closing is not acquired before the timer reaches the preset screen closing time, closing the display.

In practical application, if the instruction for canceling the screen closing is not obtained, that is, the user does not perform the operation of canceling the screen closing before the countdown of the screen closing reaches 0s, the display is closed after the timer reaches the preset screen closing time. In practical application, the music in the display device playing terminal can be only called by the loudspeaker in the display device, so that the display can be closed when the music is played, and the electric energy consumption is saved.

Since music played by the terminal generally transmits an audio signal in the form of an audio stream to the display device 200. When the display device 200 plays music in the terminal, it is required that the terminal and the display device 200 remain wireless at all times. Thus, as shown in fig. 13, in some embodiments, after acquiring the terminal audio signal by the bluetooth module, the controller is further configured to: s235: and monitoring the wireless connection state of the Bluetooth module and the sound output device.

For example, after the display device 200 and the mobile phone are successfully paired, a wireless connection is established, that is, the mobile phone sends an audio stream through the bluetooth module, and the speaker of the display device 200 can convert the audio stream into a sound signal in real time. The controller 210 may read the paired device status of the bluetooth module, and disconnect the bluetooth module of the display device 200 from the terminal when the mobile phone closes the bluetooth connection or leaves the bluetooth connection range.

S236: and if the Bluetooth module is disconnected with the sound output device, controlling the display to close the picture corresponding to the music playing application.

When the mobile phone closes the bluetooth connection or leaves the bluetooth connection range, the bluetooth module is disconnected from the terminal, and the display device 200 cannot receive the audio signal of the terminal through the bluetooth module. At this time, the display may be controlled to close the screen of the music playing application, that is, the screen corresponding to the "Hi music" application is no longer displayed. Meanwhile, a prompt page can be displayed in the user interface to prompt that the current bluetooth module is disconnected from the terminal, for example, display "disconnected from the mobile phone and exiting Hi music" in a prompt screen.

S237: and controlling the Bluetooth module to establish wireless connection with the sound input device, or closing the Bluetooth module.

When the Bluetooth module is disconnected with the terminal, the music playing application is logged out. At this time, the bluetooth module may be controlled to establish a wireless connection with the sound input device, that is, the wireless transmission mode of the bluetooth module is set to a transmission mode, so that the display apparatus 200 can establish a connection with other terminal apparatuses, such as a sound apparatus, etc. Or the bluetooth module is turned off to avoid that other sound output devices output audio signals to the display device 200 through the bluetooth module, so as to influence the self sound effect of the display device 200.

In some embodiments, after the user inputs an instruction for starting the music playing application, the controller is further configured to:

s201: the current transmission mode of the Bluetooth module is obtained.

In practical application, the current transmission mode of the bluetooth module can be obtained by searching and reading the attribute value through the attribute reading process while executing the starting instruction. Taking the bluetooth connection as an example, the controller 210 may call bluetooth frame, and read an attribute value named "persistence.

S202: and if the current transmission mode is a sending mode, setting the wireless transmission mode of the Bluetooth module to a receiving mode.

For example, if "persistence.settings.blue_sink=1" is read by the attribute reading process, determining that the transmission mode of the current bluetooth module is the reception mode; if "persistence.settings.blue_sink=0" is read by the attribute reading process, it is determined that the transmission mode of the current bluetooth module is the transmission mode. When the current transmission mode of the bluetooth module is the receiving mode, the bluetooth module does not act to avoid a switching error, so that the display device 200 cannot play the music in the terminal. And when the transmission mode of the Bluetooth module is a sending mode, setting the wireless transmission mode of the Bluetooth module as a receiving mode so as to receive the audio signal sent by the terminal.

s203: and checking the starting state of the Bluetooth module.

In practical applications, since the wireless connection switch of the display device 200 is in the off state in some cases, the display device 200 cannot establish wireless connection with other devices. Therefore, it is necessary to set the on state of the bluetooth module to on.

S204: and if the Bluetooth module is not started, starting the Bluetooth module.

For example, after a user inputs an instruction for starting a music playing application, when a picture corresponding to the music playing application is displayed, the current starting state of the bluetooth module can be checked, and if the starting state is the starting state, the wireless transmission mode is directly changed into the receiving mode; and if the current starting state is not started, starting the Bluetooth module by calling a control program. In practical applications, if the bluetooth module is not turned on, a screen for turning on the wireless connection may be displayed through a prompt screen, for example, the display screen includes "bluetooth is turned off, is it turned on? ". And after the prompt screen, jump to the "setup" interface so that the user can select "bluetooth" - "bluetooth switch", and enable the bluetooth module of the display device 200.

It should be noted that, if the current on state is unopened, the user is guided to complete the wireless connection through the option screen and the prompt screen. As shown in fig. 14 and 15, a prompt message, such as a graphic and/or text, may be displayed in the user interface to guide the user to complete the operation required to be performed on the terminal, and the bluetooth module is started and the corresponding pairing process may be implemented through a background program of the operating system.

If the music playing application is exited in the user interface, i.e. the user no longer plays the music in the terminal via the display device. Since the wireless connection relationship between the terminal and the display device is still maintained, the audio signal in the terminal is also transmitted to the display device 200. In order to avoid sounds such as operation alert sounds in the terminal from being played in the display device 200 as well, it is necessary to eliminate the influence by setting the transmission mode of the bluetooth module. In some embodiments, the user input further includes an exit instruction indicating to exit the music playing application; the controller is further configured to:

s301: and acquiring an instruction input by a user for exiting the music playing application.

S302: controlling the display to close the picture of the music playing application;

s303: and controlling the Bluetooth module to establish wireless connection with the sound input device, or closing the Bluetooth module.

As shown in fig. 7, when the user selects the exit option or clicks the return key on the control device 100 in the Hi music application interface, the generation of the exit instruction may be triggered. After the user inputs the instruction for exiting the music playing application, the picture of the music playing application can be closed first, and then the Bluetooth module and the sound input device are controlled to establish wireless connection, or the Bluetooth module is closed, so that other audio signals in the display equipment playing terminal are prevented from influencing the sound playing process of the display equipment.

In one implementation, after the user inputs an instruction for exiting the music playing application, the user interface may be switched from the Hi music program screen to the root directory of the operation interface on the one hand, and may be acquired by the controller 210 to set the wireless transmission mode of the bluetooth module on the other hand.

For example, after acquiring the exit instruction, the controller 210 may acquire the transmission mode of the current bluetooth module by reading the attribute value "persistence. If the attribute value "persistence.settings.blue_sink=1" is read, that is, the transmission mode representing the current bluetooth module is the reception mode. Since the speaker of the display device 200 plays sound in the terminal in the receiving mode to affect sound of the original resource of the display device, it is necessary to change the transmission mode, i.e., to set the wireless transmission mode of the bluetooth module to the transmitting mode.

A prompt screen for changing the transmission mode may also be presented through the user interface, for example, a dialog box for presenting "is Hi music exited, is it switched to be sound? "etc. and below the prompt text" ok "and" cancel "etc. button controls may be presented for selection by the user. If the user selects to click the "ok" button, a connect put device instruction is generated.

Based on the above display device, the embodiment of the present application further provides a method for playing music in a terminal, as shown in fig. 8, where the method includes the following steps:

s1: receiving an instruction input by a user on a user interface, wherein the instruction is used for starting a music playing application;

s2: the Bluetooth module is controlled to establish wireless connection with the sound output device;

s3: and receiving the audio signal output by the sound output device and sending the audio signal to an audio output interface.

According to the method for playing music in the terminal, the Bluetooth module is controlled to establish wireless connection with the sound output device by receiving the instruction for starting the music playing application, which is input by the user at the user interface, so as to receive the audio signal output by the sound output device, and the audio signal is sent to the audio output interface, so that the audio signal generated by playing music by the sound output device can be received by the display device and played by the loudspeaker of the display device.

In one implementation manner, the present application further provides a method for playing music in a terminal, including:

s10: receiving an instruction input by a user on a user interface, wherein the instruction is used for starting a music playing application;

S20: setting the Bluetooth module to be in a transmission mode as a receiving mode;

s30: and controlling the Bluetooth module to establish wireless connection with the sound output device.

In the above embodiment, the bluetooth connection mode of the television defaults to the A2DP Source form as the audio output Source. When a music playing application such as Hi music is opened, a switching program of a wireless transmission mode is initiated, so that the mode of the television Bluetooth device is switched from an A2DP Source form serving as an audio output Source to an A2DP Sink form serving as an audio receiver, and the audio signal of a terminal such as a mobile phone or PAD can be received.

Meanwhile, music playing applications such as Hi music can also be used for reminding a user to pair and connect a television with devices such as a mobile phone or a PAD. After the pairing connection, the television switches the A2DP to the Sink mode, the mobile phone is used as the A2DP Source, and if the user plays the audio file in the mobile phone, the audio file is streamed to the television to start playing. After the Hi music monitors the music file played by the mobile phone, the user is prompted to jump to a countdown screen closing interface through a pairing connection interface; the user selects 'off screen' in the countdown screen-off interface and then performs screen-off action, and if the user selects 'cancel screen-off' in the countdown interface, the user can use 'Hi music' interface in the display.

According to the method for playing music in the terminal, the transmission mode of the Bluetooth module can be set to be the receiving mode by receiving the instruction for starting the music playing application, which is input by the user at the user interface, so that the Bluetooth module and the sound output device are in wireless connection, and accordingly an audio signal generated by playing music by the sound output device can be received by the display device and played by the loudspeaker of the display device.

The foregoing detailed description of the embodiments is merely illustrative of the general principles of the present application and should not be taken in any way as limiting the scope of the invention. Any other embodiments developed in accordance with the present application without inventive effort are within the scope of the present application for those skilled in the art.
