摘要： A system for processing a media stream across several channels simultaneously comprises means for observing a data stream on a data bus, means for identifying media streams within said data stream, means for associating media stream data objects with their respective media streams, a multi channel media stream processor, wherein said media processor processes media stream data across a plurality of channels, in parallel, and means for monitoring and saving state of said processor as said processor switches from an original media stream to a next media stream, wherein, if said processor switches back to said original stream, a state associated with said original stream is reloaded.
