Abstract
In audio/video (AV) capture, two video streaming adapters (VSAs) receive an original input video signal and a compressed input video signal respectively to generate an uncompressed video streaming and a compressed video streaming respectively. The uncompressed video streaming and the compressed video streaming are transmitted to an external device by way of time division duplex. An interlock mechanism prevents concurrent transmission of the uncompressed video streaming and the compressed video streaming, so that the loss of real-time video streaming is reduced.
