Abstract
A control signal transmission circuit and a control signal receiving circuit for an audio/video interface are provided. The control signal transmission circuit includes an audio/video interface encoder, a signal packaging circuit and a data allocator. The audio/video interface encoder is configured to receive an audio packet and supports a user-defined packet format. The signal packaging circuit is configured to receive a first control signal and package the first control signal into a control data packet according to the user-defined packet format. The data allocator is configured to receive a video data and a second control signal and to mix the second control signal and the video data to generate a mixed data packet. The audio/video interface encoder packages the control data packet, the mixed data packet and the audio packet according to an audio/video transmission protocol to generate an audio/video and control data.
