Description

technical field [0001] The invention relates to an audio and video transmission system, in particular to a wireless audio and video transmission system. Background technique [0002] In recent years, with the rapid development of the Internet and extremely rich network resources, people can obtain various audio and video resources from the Internet, which greatly enriches people's lives. But the display screen of computer is smaller, and sound effect is also relatively poor, can't satisfy people's pursuit to perfect audio-visual effect. With the popularity of large-screen LCD TVs, people look forward to playing audio and video resources on computers through LCD TVs, combining the massive resources on the Internet with the perfect audio-visual effects of large-screen LCD TVs, and truly realizing high-quality audio-visual enjoyment. Nowadays, people mostly connect computers and TV sets through wired methods. The wiring is cumbersome, and the computer needs to be moved around,...
