AUDIO AND VIDEO TRANSMITTING DEVICE, AUDIO AND VIDEO RECEIVING DEVICE, AND WIRELESS AUDIO AND VIDEO TRANSFER SYSTEM

摘要

An audio and video transmitting device includes a source-end connecting unit configured to receive an audio and video signal from a video source; a transmitting-end processing unit configured to process the audio and video signal and generate a processed audio and video signal; a first wireless unit configured to modulate the processed audio and video signal and generate a modulated audio and video signal; a transmitting-end antenna configured to send the modulated audio and video signal; and a transmitting-end peripheral interface configured to receive a first peripheral information from a source-end peripheral device and send the first peripheral information to the transmitting-end processing unit which sends the first peripheral information to the video source through the source-end connecting unit. Thus, the video source such as the smart device acquires data from peripheral devices through the transmitting-end peripheral interface, which increases the interaction means of the audio and video transmitting device.
