The invention provides an audio state display method of power amplifier equipment, display equipment and the power amplifier equipment. After the power amplifier equipment is connected with the display equipment through the ARC, if a user wants to adjust the audio state of the power amplifier device, the display device can be controlled through the control device, and then the display equipment sends the audio state control instruction and the audio state request instruction to the power amplifier equipment. The power amplifier equipment can adjust the current audio state to the target audio state according to the audio state control instruction, and can actively send the adjusted target audio state back to the display device according to the audio state request instruction. Finally, the display equipment displays the target audio state of the power amplifier equipment for the user, so that the user can know the audio state of the power amplifier equipment. The display equipment can control the power amplifier device to actively report the audio state according to the control of the user, and the problem that the user experience is affected due to the fact that part of the power amplifier devices cannot actively report the audio state is avoided.
Description
technical field [0001] The present application relates to the field of display technology, and in particular to an audio state display method of a power amplifier device, a display device and a power amplifier device. Background technique [0002] When the connection between the display device and the external power amplifier is established through ARC (Audio Return Channel, audio return channel), the user can use the remote control to manually adjust the volume of the external power amplifier or mute the external power amplifier. Under normal circumstances, the external power amplifier device will actively report the current audio status of the power amplifier device, such as volume value or mute state, to the display device by sending a CEC (Consumer Electronics Control, Consumer Electronics Control) command. The display device will display the audio status, thereby informing the user of the audio status of the currently connected external power amplifier device. [0003]...
