The user interface module 2911-3 is configured to provide an object for displaying a user interface, so that each application program can access the object, and user operability can be achieved.

Control applications 2911-4 for controlling process management, including runtime applications and the like.

The event transmission system 2914 may be implemented in the operating system 2911 or in the application 2912. In some embodiments, an aspect is implemented within the operating system 2911, while implemented in the application 2912, for listening for various user input events, and will implement one or more sets of predefined operations in response to various events referring to the recognition of various types of events or sub-events.

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

The live television application program can provide live television through different signal sources. For example, a live television application may provide television signals using input from cable television, radio broadcasts, 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.

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

The media center application program can provide various applications for playing multimedia contents. For example, a media center, which may be other than live television or video on demand, may provide services for a user to access various images or audio through a media center application.

The application program center can provide and store various application programs. The application may be a game, an application, or some other application associated with a computer system or other device that may be run on the smart television. The application center may obtain these applications from different sources, store them in local storage, and then be operable on the display device 200.

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

In the user interface, at least one option is designated to graphically and/or textually represent the music playing application. Since the third-party application generally does not have the capability of playing music in the terminal, in the embodiment of the present application, a music playing application, such as "Hi music", may be built in the operating system level. When the option picture corresponding to the music playing application is selected, the music playing application can be started, and a program interface specific to the music playing application is displayed in the user interface. For example, after the Hi music is selected and opened, a program interface corresponding to the Hi music can be presented in the user interface. As shown in fig. 7, a screen such as a moving picture or a character representing the music playing function is displayed.

In practical applications, the option being selected means that the user clicks the option screen through a series of operations on the remote controller. In the user interface, an option screen is selected and can be displayed through the selected mark. The selection of the selection picture can be represented by a display mode such as a selection box, a highlighted text, an enlargement, a lower menu display and the like. For example, a selection box marked as a rectangular structure is selected. The user adjusts the position of the selection frame through the up, down, left and right keys on the remote controller, after the selection frame selects the application program icon corresponding to the Hi music, the Hi music application can be started through clicking the ok key on the remote controller, and at the moment, the option picture representing the Hi music is selected.

The user can 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 practical applications, the user input may be an interactive operation based on a remote controller. For example, after the application icon corresponding to the "Hi music" is selected by the selection box on the user interface by operating the remote controller, 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 such as a voice system, a gesture system, etc. For example, the user may enter the speech "open Hi music" through the speech 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 a 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 the speaker, thereby playing 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 transmission mode and a reception mode. The transmission mode is a mode in which the display apparatus 200 serves as a signal source or a transmission source of a signal or data. The display device 200 may send the generated signal to other devices in a wireless manner, so as to display the specific video and audio resources by using hardware of the other devices. The receiving mode is that in this mode, the display device 200 can receive signals or data from other devices (terminals) through the bluetooth module, so as to display audio and video resources by using hardware on the display device 200.

For example, the bluetooth A2DP mode at the display apparatus 200 includes "source (transmission mode)" and "sink (reception mode)". If the terminal is wirelessly connected with the display device through the bluetooth connection, the A2DP mode of the display device 200 is controlled and set as the sink mode when the user input is received as a start instruction.

In order to play music in the terminal at the display device 200, the controller 210 may judge 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 device 200 is set to the receiving mode, the display device 200 may receive the audio signal sent by the terminal in real time and play the received audio signal through the speaker.

Therefore, after the wireless connection between the display device and the terminal is completed, the wireless transmission mode can be set to the receiving mode according to the starting instruction input by the user. At this time, the display device 200 may be regarded as a wireless sound box connected to the terminal, and as the terminal plays the audio resource, the display device 200 may play music corresponding to the audio resource. Therefore, the entire music playing process does not require transfer of audio source files 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 programs such as decoding of the music file are still operated 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 music playing process, in practical applications, a wireless connection may be established between the terminal and the display device 200. For example, the setting-related program may be started through a "setting" option screen in the user interface. After the setting program is started, a picture related to setting can be displayed on the user interface, a user can send a control instruction through the control device 100, a bluetooth switch is selected in the user interface, and a bluetooth module of the display device is started. And then sequentially selecting Bluetooth connection mode and mobile phone connection mode 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 the music in the terminal through the operation on the terminal. Since the transmission mode of the display device 200 is the reception mode, when the terminal plays music, an audio signal is generated and transmitted to the display device 200 through a wireless connection manner such as bluetooth, so that the audio signal is converted into music through a speaker of the display device 200. In the course of playing music, a screen including the playing course, for example, "Hi music in use" or the like, may also be presented in the user interface.

In some embodiments of the present application, the user interface further includes a prompt screen, and the prompt screen displays the prompt information through graphics and/or text. For example, after the controller 210 selects execution of the wireless connection setting program, the prompt screen may display the execution result of the wireless connection setting program. That is, after the option screen corresponding to the "bluetooth switch" is selected to be executed, the prompt screen may display "bluetooth is turned on" or "bluetooth is turned 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 executing the wireless connection setting program corresponding to the option screen of "connect mobile phone" by the controller 210, a prompt screen of "connect mobile phone … please wait" is displayed in the user interface, and after the connection of the mobile phone is completed, a prompt screen of "connect mobile 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 establishes wireless connection with a sound output device.

For example, the user interface includes an icon "Hi music" indicating a music playing application, and when the user manipulation is selected and identified to the icon, the user interface may click "ok" to open the application, and at this time, the user interface generates an instruction for starting the music playing application, and the controller 210 may obtain the starting instruction. Whether the bluetooth module has established wireless connection with the sound output device, that is, whether the display device has performed matching connection with the terminal, and whether the transmission mode of the display device 200 is a sink mode in the current matching connection form may be detected.

S22: and if the Bluetooth module establishes wireless connection with the sound output device, acquiring the 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, instead of a speaker on the terminal for playing sound. When a user selects to play music on the terminal, the terminal decodes the audio file to generate an audio signal and sends the generated audio signal through Bluetooth.

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

The display device 200 receives the corresponding audio signal through the bluetooth module, and forwards the audio signal to the speaker of the display device, and plays 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 a 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 cannot 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 the connection between the bluetooth module and the terminal is established, a screen with a prompt function, such as "please connect to the mobile phone", is displayed in the form of a prompt screen in the user interface, and after the user selects and determines, the user interface jumps to an option screen corresponding to "bluetooth connection mode-mobile phone connection".

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, the display device 200 can play all music in the terminal without installing the same music playing software in the display device 200 and the terminal or copying the audio file to the display device 200.

If the bluetooth module has established a wireless connection with the terminal, the display device 200 may receive an audio signal of the terminal. However, since the terminal and the display device 200 are two different devices, when the user plays music in the terminal, the user needs to perform a playing operation on the terminal to generate an audio signal, and then transmit the generated audio signal through bluetooth. Thus, in some embodiments, as shown in fig. 10, after the bluetooth module establishes the 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 an 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. And if the Bluetooth module is determined to receive the audio signal from the terminal, determining that the terminal plays 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, the audio signal sent by the terminal can be acquired, that is, the audio stream sent by the terminal is received through the bluetooth module. The Bluetooth module can arrange the audio stream and forward the audio stream to a sound playing circuit of the display device after receiving the audio stream so as to transmit the audio stream to a loudspeaker of the display device.

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

After acquiring the audio signal sent by the terminal, the controller 210 further controls the speaker to start operation, and converts the electrical signal corresponding to the audio signal into a sound signal. Therefore, when the audio stream is continuously input, the loudspeaker can play music corresponding to the audio file in the terminal.

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

s231: and controlling the display to display a screen closing prompt picture and starting a timer.

After the audio signal sent by the terminal is acquired by the bluetooth module, the display device 200 may transmit the audio signal to a 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, the prompt screen displayed in the user interface has prompt text such as "close screen soon".

In practical applications, since a user may perform other operations in the user interface when playing music in the terminal using the display device 200, after the display device plays music, the screen may be closed after delaying a preset time, that is, a timer is started in the control program, and after the timer reaches the preset screen closing time, the controller may be triggered to perform corresponding operations. The preset screen-off time can be adjusted according to the display equipment without signals, and is generally 5-10s. As shown in fig. 12, a countdown screen, such as "screen off countdown: xs ", etc.

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

While displaying the screen closing prompt picture, a part of options can be added in the prompt picture so that a user can select whether to close the screen through operation. For example, in the "screen off countdown: and a button control can be displayed below the xs, and prompt information of 'canceling screen closing' is arranged on the button control. When the user selects the 'cancel screen off' button control through operation, a cancel screen off instruction can 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, namely before the screen closing countdown reaches 0s, if the user selects screen closing canceling, the controller receives a screen closing canceling instruction, and at the moment, the controller cancels the screen closing countdown and does not close the screen. At this time, the original user interface, i.e., the screen before entering the "Hi music", or the music playing application prompt screen may be displayed on the screen. The prompt screen of the music playing application may include graphics, dynamic videos, 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 a screen closing cancelling instruction is not acquired, that is, the user does not perform screen closing cancelling operation before the screen closing countdown reaches 0s, the display is closed after the timer reaches the preset screen closing time. In practical application, only the loudspeaker in the display device can be called by playing the music in the terminal through the display device, so that the display can be closed when the music is played, and the power consumption is saved.

Since music played by the terminal generally transmits an audio signal to the display apparatus 200 in the form of an audio stream. When the display apparatus 200 plays music in the terminal, it is required that the terminal always maintains a wireless connection with the display apparatus 200. Thus, as shown in fig. 13, in some embodiments, after acquiring the terminal audio signal through 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 is successfully paired with a mobile phone, a wireless connection is established, that is, the mobile phone sends an audio stream through the bluetooth module, and a speaker of the display device 200 may 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 when the mobile phone closes the bluetooth connection or leaves the bluetooth connection range, the bluetooth module of the display device 200 is disconnected from the terminal.

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 at this time, the display device 200 cannot receive the audio signal of the terminal through the bluetooth module again. 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, "the Bluetooth module is disconnected from the mobile phone and exits from Hi music" is displayed in a prompt screen.

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

When the Bluetooth module is disconnected with the terminal, the music playing application is quitted. 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 may be set to a transmission mode, so that the display apparatus 200 can establish a connection with other terminal apparatuses, such as a stereo, and the like. Or, the bluetooth module is turned off to prevent other sound output devices from outputting audio signals to the display device 200 through the bluetooth module and affecting the sound effect of the display device 200.

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

s201: and acquiring the current transmission mode of the Bluetooth module.

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 bluetooth connection as an example, the controller 210 may call a bluetooth frame, and read an attribute value named "persistence.

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

For example, if "persistence. Settings. Bluetooth _ sink =1" is read through the attribute reading process, it is determined that the transmission mode of the current bluetooth module is the reception mode; and if the attribute reading process reads that the transmission mode of the current Bluetooth module is the transmission mode, and the attribute reading process reads that the transmission mode of the current Bluetooth module is the transmission mode. When the transmission mode of the current bluetooth module is the receiving mode, the operation is not performed, so as to avoid switching errors, which may cause the display device 200 not to play 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, the starting state of the current bluetooth module may be checked when a picture corresponding to the music playing application is displayed, and if the starting state is starting, the wireless transmission mode is directly changed into the receiving mode; and if the current starting state is not starting, starting the Bluetooth module by calling the control program. In practical applications, if the bluetooth module is not turned on, the screen for turning on the wireless connection may be displayed through the prompt screen, for example, the display screen includes "bluetooth is turned off, is it turned on now? ". And after the prompt screen, jump to a 'setup' interface, so that the user can select 'bluetooth' -a 'bluetooth switch' to start the bluetooth module of the display device 200.

It should be noted that, if the current activation state is not activated, the user is guided to complete the wireless connection through the option screen and the prompt screen. As shown in fig. 14 and fig. 15, prompt information, such as graphics and/or text, may be displayed in the user interface to guide the user to complete operations required to be performed on the terminal, and the bluetooth module starting and the corresponding pairing process may be implemented by a background program of the operating system.

If the music playing application is exited in the user interface, the user no longer plays the music in the terminal through 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 that sounds such as operation alert tones in the terminal are also played in the display device 200, it is necessary to eliminate the influence by setting the transmission mode of the bluetooth module. In some embodiments, the user input further comprises an exit instruction indicating to exit the music playing application; the controller is further configured to:

s301: and acquiring an instruction which is input by a user and used 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 a sound input device, or closing the Bluetooth module.

As shown in fig. 7, when the user selects an exit option in the "Hi music" application interface or clicks a return key on the control device 100, generation of an exit instruction may be triggered. After the user inputs an instruction for exiting the music playing application, the user can close the picture of the music playing application first, and then control the bluetooth module to establish wireless connection with the sound input device, or close the bluetooth module, so as to prevent the display device from playing other audio signals in the terminal and influencing the sound playing process of the display device.

In one implementation, after the user inputs an instruction to exit 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 on the other hand, so as to set the wireless transmission mode of the bluetooth module.

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, it means that the transmission mode of the current bluetooth module is the reception mode. Since the speaker of the display device 200 plays the sound in the terminal in the receiving mode, which affects the sound of the original resource of the display device, the transmission mode needs to be changed, that is, the wireless transmission mode of the bluetooth module is set to the transmitting mode.

A prompt screen to change the transmission mode may also be presented through the user interface, for example, in the form of a dialog box showing "has the Hi music exited, has the Hi music switched to a polyphonic ring? "etc., and button controls such as" confirm "and" cancel "can be presented under the prompt text for the user to select. If the user selects to click the "OK" button, a connect play out device instruction is generated.

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

s1: receiving an instruction which is input by a user on a user interface and is used for starting a music playing application;

s2: controlling the Bluetooth module 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 technical scheme, the method for playing the music in the terminal can control the Bluetooth module to establish wireless connection with the sound output device by receiving the instruction which is input by the user at the user interface and used for starting the music playing application, so that the audio signal output by the sound output device is received, and the audio signal is sent to the audio output interface, so that the audio signal generated by the sound output device playing the music can be received by the display device and played by the loudspeaker of the display device.

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

s10: receiving an instruction which is input by a user on a user interface and is used for starting a music playing application;

s20: setting the transmission mode of the Bluetooth module to be 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 an audio signal of a terminal such as a mobile phone or a PAD can be received.

Meanwhile, the music playing application such as 'Hi music' can also be used for reminding a user to pair and connect the television with equipment such as a mobile phone or a PAD. After the pairing connection, the television end is switched to the Sink mode from the A2DP 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 transmitted to the television end in a streaming mode to be played. After the Hi music is monitored to play the music file on the mobile phone, the user is prompted to jump from the pairing connection interface to a countdown screen closing interface; the user performs the screen-off action if the user selects "screen-off" at the countdown screen-off interface, and the user may use the "Hi music" interface in the display if the user selects "cancel screen-off" at the countdown interface.

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

The embodiments provided in the present application are only a few examples of the general concept of the present application, and do not limit the scope of the present application.
