Abstract:
1. A system for simultaneously playing back multiple video elementary streams using one playback channel, the system comprising: a memory configured to store the multiple video elementary streams; a demultiplexer configured to distinguish each of the multiple video elementary streams; a decoder configured to simultaneously decode the multiple video elementary streams; a memory buffer configured to store the multiple video elementary streams from the memory and to provide the multiple video elementary streams to the demultiplexer using a single playback data feeder during the playback of the multiple video elementary streams; a video decoder buffer configured to store the multiple video elementary streams from the demultiplexer and to provide the multiple video elementary streams to the decoder; a controller configured to determine a plurality of addresses in the memory storing each particular one of the multiple video elementary streams; and a processor configured to fetch particular ones of the multiple video elementary streams from the memory, the processor further configured to write a plurality of identifiers in the multiple video elementary streams.
