Abstract

ATM (asynchronous transfer mode) transport and cell-loss concealment techniques for MPEG video are discussed in this paper. 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 for example channel scenarios are given, demonstrating that useful decoder operation can be maintained at cell loss rates in the region of 10-3 and 10-2- 10-1 with one-tier and two-tier transmission, respectively.
