Abstract:
A video encoder and corresponding method are described for enabling fast channel change of compressed video, where a video encoder for receiving input pictures and providing compressed stream data includes a normal encoding portion for receiving input pictures and providing normal stream data, a lower-quality encoding portion for receiving input pictures and providing channel change stream data, and a multiplexor in signal communication with each of the normal and lower-quality portions for receiving and combining the normal and channel change data streams.
