ATM transport and cell-loss concealment techniques for MPEG video

Robust video compression and transport approaches are essential for operation over emerging ATM-based broadband ISDN and gigabit networks characterized by packet (cell) losses due to congestion. The same techniques also apply to delivery of digital TV and HDTV over cable, satellite, or terrestrial media in which high bit-error rates may occasionally be experienced. A specific cell-based MPEG video transport approach applicable to a variety of media is described for both one-tier and two-tier transmission alternatives. Decoder cell-loss concealment techniques supported by this transport format are introduced, and typical design issues are discussed. Simulation results showing end-to-end MPEG video quality are given illustrating the performance of the transport and concealment schemes under consideration for example channel scenarios.<>
