Wireless audio and video transmitter

The utility model provides a wireless audio and video transmitter comprising an audio encoder used for carrying out compression encoding processing upon audio streams, a video encoder used for carrying out compression encoding treatment upon video streams, a multiplexer respectively connected with the audio encoder and the video encoder, a transmission processor connected with the multiplexer, and a transmission front end connected with the transmission processor. The video encoder comprises more than two delay modes, and delays allowed by the delay modes are different. The multiplexer is used for multiplexing audio code streams outputted by the audio encoder and video code streams outputted by the video encoder, such that single code stream is generated. The transmission processor is used for carrying out baseband signal transmission processing upon the single code stream. The transmission front end is used for converting the signals outputted by the transmission processor into radio frequency analog signals. The video encoder of the wireless audio and video transmitter is a multi-delay video encoder with which the delay modes can be selected. The wireless audio and video transmitter has wide application prospect.
