[0028] Currently, all audio-video interaction systems on the market are equipped with microphones and cameras, and can therefore support online interaction functions (e.g., video conferencing). However, when a user mutes the audio-video interaction system, the microphone cannot be turned off and there is no warning function, which leads to a poor user experience.

[0029] In response to the above problems, an embodiment of the present application provides an audio-video interaction system, which, as shown in FIG. 1, includes a control module 10, a microphone module 30, a first instruction module 40, and a terminal device 20, where the control module 10 includes a video processor 11 electrically connected to the terminal device 20 and the first instruction module 40, respectively, and the terminal device 20 is electrically connected to the microphone module 30.

[0030] In the audio-video interaction system according to an embodiment of the present application, a communication path is further provided between the terminal device 20 and the video processor 11 and the microphone module 30, and a communication path is further provided between the video processor 11 and the first instruction module 40.

[0031] When a user performs a mute operation in the audio-video interaction system, the terminal device 20 receives the mute execution command, and in response to the mute execution command, outputs a first command to the microphone module 30 to instruct the microphone module 30 to be turned off, thereby preventing a problem that complete muting cannot be achieved because the microphone module 30 remains on when the audio-video interaction system is in a mute state. Meanwhile, when the terminal device 20 further receives the mute execution command, it outputs a second command to the control module 10 to instruct the first instruction module 40 to control the emission of light, thereby alerting the user that the audio-video interaction system is currently in a mute state.

[0032] As described above, when a user performs a mute operation in the audio-video interaction system according to the embodiment of the present application, the user can turn off the microphone module 30 to achieve complete muting of the audio-video interaction system, and can grasp the status of the audio-video interaction system through the first instruction module 40. Therefore, the user experience is improved.

[0033] When the user cancels the mute operation in the audio-video interaction system, the terminal device 20 receives the mute cancel command, and outputs a third command to the microphone module 30 in response to the mute cancel command to instruct the microphone module 30 to turn on. Meanwhile, when the terminal device 20 further receives the mute cancel command, it outputs a fourth command to the control module 10 to instruct the first instruction module 40 to be turned off, thereby alerting the user that the audio-video interaction system is currently in a voice pickup state.

[0034] As can be seen from the above, the user can control the microphone module 30 and the first instruction module 40 according to the audio-video interaction system of the embodiment of the present application. When performing a mute operation in the audio-video interaction system of the embodiment of the present application, the user controls the microphone module 30 to be turned off and the first instruction module 40 to be illuminated. When canceling a mute operation in the audio-video interaction system of the embodiment of the present application, the user controls the microphone module 30 to be turned on and the first instruction module 40 to be turned off.

Here, the first command is a command based on a Human Interface Device (HID) protocol for instructing the microphone module 30 to be turned off. The second command is a mute code sub-table, and the first control signal is a high-level signal. After executing the second command transmitted by the terminal device 20, the control module 10 outputs a mute code sub-table to the terminal device 20 via the Uart interface, thereby notifying the terminal device 20 that the second command has been executed.

[0036] In an embodiment of the present application, when the terminal device 20 receives an unmute command, the terminal device 20 is configured to output a third command to the microphone module 30 via the USB interface and output a fourth command to the control module 10 via the Uart interface.
