The application center may obtain these applications from different sources, store them in local storage, and then be operable on the display device 200.

With the wider application of power amplifier sound equipment in home theater, multimedia classroom, mini-conference, etc., the requirement of people for supporting power amplifier sound equipment is increasing. In some application scenarios, the display device is connected with an external power amplifier, such as a sound device, in a specific manner, so that the audio output channel is no longer limited to the speaker built in the display device. For an external power amplifier supporting an ARC (Audio Return Channel) and/or an ARC (enhanced Audio Return Channel) function, the external power amplifier may be connected to a display device through an HDMI (High Definition Multimedia Interface). The display device can transmit the audio signal back to the power amplifier device by the sound transmission technology to perform signal amplification processing and output.

In some application scenarios, a plurality of HDMI interfaces are generally preset on the display device, and the display device can be connected with external power amplifier devices through the HDMI interfaces. Fig. 6 is a schematic view of a scene that a power amplifier device shown in some embodiments of the present application is connected to a display device, and as shown in fig. 6, the power amplifier device 600 is connected to the display device 200 through an HDMI harness.

Fig. 7 is a schematic diagram illustrating a hardware connection between a power amplifier device and a display device in some embodiments of the present application, and in the example illustrated in fig. 7, the display device 200 and the power amplifier device 600 support an ARC function. As shown in fig. 7, the voice feedback is performed by using a Utility signal line, and the interactive command between the display device 200 and the power amplifier device 600 is performed through a CEC signal line. In this example, the transmission line of the audio data and the command data is completely separated, and time-sharing control by software is not required. The transmission of command data is serial communication in which the process belongs to a single line, and is called CEC protocol.

However, at present, due to the configuration of the display device itself, when the system of the display device is in the STR standby state, the system is frozen, and therefore, the change of the state of the external power amplifier device cannot be detected when the display device is in the STR standby state. After the display device STR is restarted and started, if the state of the external power amplifier device changes, if an HDMI cable connected with the display device is artificially pulled out, or the external power amplifier device is directly pulled out from the HDMI cable, the state of the external power amplifier device can be changed, and for the display device, the display device STR cannot receive related information to know that the state of the external power amplifier device at the moment has changed, and make an erroneous judgment according to the incorrect power amplifier device information which is not updated after the display device STR is restarted and finally cause the problem that the power amplifier does not make a sound or the sound changes suddenly. For example, after the STR is restarted and turned on, when audio output needs to be selected, the default state before the STR is restarted is still selected, that is, the external power amplifier is selected to output audio, but the state of the external power amplifier is changed, so that sound cannot be emitted or the volume is suddenly adjusted to the volume when the power amplifier is connected.

At present, after a display device configured as a Vidaa operating system is connected with a power amplifier through an HDMI cable, a cable link message is received, whether an ARC device can ping or not is detected by sending a ping command, and if the display device is pulled out after STR standby, the state of the ARC device cannot be reported in time. After the display equipment STR is in standby and restarted, CEC messages are not exchanged in time, the power amplifier information recorded by the display equipment is still the connection state and the volume of the power amplifier before the STR is in standby, and the Audio Output is still ARC and is not updated to TV Speaker, so that the volume suddenly rises to be the volume when the power amplifier sound box is connected when the display equipment is silent or the volume is adjusted.

In some embodiments, after the display device is booted, FIG. 8 illustrates the UI of an Audio Output (Audio Output) setup page, where different categories of Audio Output channels may be presented in the Audio Output menu, such as, but not limited to, TV Speaker, ARC, and Spdif Only, among others. The ARC shows that the power amplifier sound box is connected through an HDMI wire, the TV Speaker is a self-contained loudspeaker of the display device, and the SPDIF shows that the external device is connected through an optical fiber wire. The Audio Output menu may also be annotated with the current status of the various Audio Output channels (optional or not). The channel in the selectable state can be selected by a user and set as a target channel for finally outputting audio; the channel in the unselected state cannot be selected by the user, and cannot be used as a target channel to output audio.

In some embodiments, when the display device is not connected to the power amplifier device, the Audio Output in the menu is set to TVSpeaker. When the display device is connected with the power amplifier sound box through the HDMI line, if the Audio Output in the menu is ARC, the video or Audio playing application is opened, and when the video or Audio is played, the user calls the volume bar to check the volume as the volume of the power amplifier device.

In some embodiments, as shown in fig. 9, when the display device is connected to the power amplifier device to play a video, the Audio Output channel in the Audio Output menu should be ARC; after the display equipment is standby, controlling the connection state of power amplifier equipment in the display equipment to be in an inactive state, namely, setting the connection state of the power amplifier equipment to be False; when the display equipment is started or restarted, the real-time state of the power amplifier equipment is requested to be acquired.

In some embodiments, if the display device STR is in standby, the access state of the power amplifier device is not changed, after the display device is restarted, the display device is connected with the real-time state of the external power amplifier device through the CEC request, and at this time, because the access state of the external power amplifier device is not changed, when the real-time state of the external power amplifier device is obtained through the CEC request, the state information fed back by the external power amplifier device can be received, and at this time, the power amplifier device is continuously connected or the self-contained sound player TV Speaker of the display device is selected to play according to the state returned by the external power amplifier device.

In some embodiments, if the current state returned by the external power amplifier device received by the display device is on, the audio output channel of the display device is set to be played by the power amplifier device; and if the current state returned by the external power amplifier received by the display equipment is off, setting the audio output channel of the display equipment as a sound player for playing. Meanwhile, the information such as the connection state, the volume and the like of the external power amplifier equipment is updated in the system interface.

In some embodiments, a user may determine whether the connection state and the volume of the external power amplifier device are adjusted to the corresponding setting state by querying the Audio Output channel information in the Audio Output menu. For example, if the current state returned by the external power amplifier device received by the display device is on, the Audio Output channel information in the Audio Output menu should be as shown in fig. 9, and the Audio Output channel in the Audio Output menu is ARC; if the current state returned by the external power amplifier device received by the display device is off, the Audio Output channel information in the Audio Output menu is shown in fig. 10, and the Audio Output channel in the Audio Output menu is a TV Speaker.

In some embodiments, when the display device plays video or audio, the user may further input a volume adjustment instruction through a remote controller or other control device to adjust the volume of the display device, and after receiving the volume adjustment instruction input by the user, the display device responds to the volume adjustment instruction to control the display device to display a volume bar corresponding to the audio output channel on the user interface. For example, if the current state returned by the external power amplifier device received by the display device is on, the Audio Output channel information in the Audio Output menu should be ARC, and the display interface displays a volume bar display interface as shown in fig. 11; if the current state returned by the external power amplifier device received by the display device is off, the Audio Output channel information in the Audio Output menu should be TV Speaker, and the display interface displays a volume bar display interface as shown in fig. 12.

In some embodiments, in order to facilitate the user to view the target volume adjusted by the power amplifier device 600, the display device 200 needs to display the specific target volume on the user interface after receiving the target volume sent back by the power amplifier device 600. As shown in fig. 11 and 12, the target volume may be displayed on the user interface in the form of a volume bar, and the length of the volume bar indicates the magnitude of the target volume.
