USB audio video (USB-AV)

USBAudioVideo (USB- AV) is a specification developed by the USB Implementers Forum( USB-IF) that allows video from a cell phone to be played on a TV.

The USB-AV specification defines how audio and video devices communicate with each other over the USB interface. The specification deals with the setting options for audio facilities for stereo or surround sound and for video playback.

USB-AV version 3.0 supports a data rate of 4 Gbit/s and can thus display HDTV in 1,080p. Version 3.1 has a data rate of 9.8 Gbit/s and is suitable for Quad-Full HD, the 4K standard of High Definition Multimedia Interface( HDMI) and 4K D-Cinema.
