CONTROL STRATEGY FOR DYNAMICALLY ENCODING MULTIPLE STREAMS OF VIDEO DATA IN PARALLEL FOR MULTIPLEXING ONTO A CONSTANT BIT RATE CHANNEL

摘要

The present invention is to provide a control scheme for multiplexing onto a constant bit rate channel by dynamically coding the plurality of streams to the video data in parallel. Control scheme encoder and a fixed bit rate to fill the channel buffer connected between the channel filling degree of the road and the compressed video data buffer as well as based in part on the relative complexity of the plurality of video data streams separate encoding for each of the video data stream a single path scheme for dynamically adapting the bit rate. The control scheme includes the step of dynamically adapting the coding for at least one stream of video frames on the basis of the relative complexity of the step of encoding a plurality of video frame streams in parallel, and the video frame. Bit rate for each video stream, the frame is only generated in the change only if the GOP boundary or scene change. Preferably, the bit rate calculation is further modified based on the buffer filling degree.
