Wireless audio and video transmitter and wireless audio and video processing method

Abstract

The present invention provides a wireless audio and video transmitter and a wireless audio and video processing method, including: an audio encoder for compressing and encoding audio streams; a video encoder for compressing and encoding video streams, the video The encoder includes more than two delay modes, and the delays allowed by each delay mode are different; the multiplexer is connected to the audio encoder and the video encoder respectively, and is used to configure the audio encoder The output audio code stream and the video code stream output by the video encoder are multiplexed to generate a single code stream; the transmission processor for performing baseband signal transmission processing on the single code stream, the transmission processor and the It is connected to the multiplexer; it is used to convert the signal output by the transmission processor into the transmitting front end of the radio frequency analog signal, and the transmitting front end is connected with the transmission processor. The video encoder of the wireless audio and video transmitter is a multi-delay video encoder, which can select the delay mode and has a wide range of application scenarios.

Description

technical field [0001] The invention relates to communication technology, in particular to a wireless audio and video transmitter and a wireless audio and video processing method. Background technique [0002] With the development of digital TV, the home wireless audio and video transmission technology has also made great progress. Traditional wireless transmitters are often implemented with discrete components, and are placed on high TV towers. The transmission power is generally thousands of watts, which requires high cost, which is not conducive to application in ordinary families. Moreover, the user's demand for digital TV is not limited to listening to / watching audio / video in digital TV, and sometimes it is necessary to convert audio / video from other devices, such as computers, game consoles, DVDs, Blu-ray players, karaoke systems, etc. Send it to a digital TV for playback. For example, the computer uploads the video image to the digital TV; or the video image of the ...
