MPEG++-a robust compression and transport system for digital HDTV

An overview is presented of the MPEG++ robust compression and transport algorithm used in ADTV (advanced digital television), a recently proposed simulcast digital HDTV (high-definition television) system. MPEG++ achieves robust delivery of compressed video through the addition of media-specific data prioritization and transport layers to a standard MPEG bit-stream. MPEG++ is described, with particular emphasis on video-specific transport features that have been added to mitigate the impact of channel errors. Simulation results using an MPEG++ software model are briefly discussed.<<ETX>>
