ALGORITHM FOR FAST FORWARD AND FAST REWIND OF MPEG STREAMS

摘要

A transport system allows delivery of MPEG video streams from a network server (50) to a media client (60) while avoiding network delays associated with transitions between files contained in these streams. A buffering system (30), a transport controller (20), and a counter (40) allow buffering and interim delivery of MPEG stream data. The transport controller (20) can either deliver MPEG stream data directly to the media client, or route data through the buffering system (30). The buffering system (30) includes a population buffer (35) for storage of interim MPEG stream data, and a transport buffer (34) for temporary storage of MPEG stream data during continuous delivery. During transitional delivery, the transport controller (20) delivers interim data to the media client (60) until the requested file is available and uses the counter to select the proper start location in the requested file.
