Flexible and robust packet transport for digital HDTV
IEEE Journal on Selected Areas in Communications, 1993Co-Authors: R Siracusa, J. Zdepski, K. Joseph, Dipankar RaychaudhuriAbstract:The packet-oriented transport approach used in the advanced digital television (ADTV) system for terrestrial HDTV broadcast is described. ADTV achieves robust HDTV delivery on terrestrial simulcast channels via MPEG video compression, prioritization of MPEG data, and 'cell-relay' type packet transport in conjunction with a two-tier physical transmission scheme. General design issues relevant to the development of the proposed transport protocol are discussed. ADTV's prioritization algorithm for partitioning MPEG-encoded video into high-priority (HP) and standard-priority (SP) bit streams is outlined. The data transport format supporting these prioritized compressed video bit streams is described. The three principal sublayers of the ADTV transport protocol are discussed in terms of specific functions, impact of system performance, and hardware implementation factors. A proof-of-concept simulation model that incorporates transport encoding and decoding functionality is outlined, and performance evaluation results are given for illustrative transmission scenarios. >

A flexible and robust packet transport protocol for digital HDTV
[Conference Record] GLOBECOM '92 - Communications for Global Users: IEEE, 1992Co-Authors: Dipankar Raychaudhuri, J. Zdepski, R Siracusa, K. JosephAbstract:A packet oriented transport protocol used in the recently proposed advanced digital television (ADTV) system for terrestrial HDTV broadcast is described. ADTV achieves robust HDTV delivery on terrestrial simulcast channels via MPEG video compressor, prioritization of MPEG data, and ATM-type cell-relay-type packet transport in conjunction with a two-tier physical transmission scheme. The three principal sublayers of the ADTV transport protocol, (1) a generic data-link/network level for addressing, priority support and error control, (2) an adaptation layer for service-specific error recovery, and (3) a video service level for higher-level resynchronization of the video decoder are discussed in terms of specific functions, impact on system performance, and hardware implementation factors. A proof-of-concept simulation model which incorporates transport encoding and decoding functionality is outlined, and performance evaluation results are given for illustrative transmission scenarios. >

mpeg a robust compression and transport system for digital HDTV
Signal Processing-image Communication, 1992Co-Authors: K. Joseph, J. Zdepski, S Ng, R Siracusa, Dipankar Raychaudhuri, Saint R Girons, T. SavatierAbstract:Abstract This paper provides a technical overview of MPEG++, a robust video compression and transport system for digital HDTV. MPEG++ forms the basis of ‘Advanced Digital Television’ (ADTV), the all-digital terrestrial simulcast system currently under development by the Advanced Television Research Consortium (ATRC). ADTV incorporates an efficient MPEG-compatible compression algorithm at its central core, with application-specific data prioritization and transport features added as separable layers. The compression process is based on a 1440×960 (1050-line 2: 1 interlaced) HDTV format, producing a selectable bit-rate in the region of 15–20 Mbit/s. The data priorization layer of MPEG++ achieves robust delivery over an appropriate two-tier modem by separating compressed video data into high- and standard-priority bitstreams with appropriate bit-rates. This priorized data is then formatted into fixed length ‘cells’ (packets) with appropriate data-link level and service-specific adaptation level headers, designed to provide capabilities such as flexible service multiplexing, priority handling, efficient cell packing, error detection and graceful recovery from errors. An outline of each of the above MPEG++ elements (i.e., compression, prioritization and transport) is given, and is followed by a description of a software model for the system. Simulation model based performance results which illustrate MPEG++ image quality and robustness are briefly reported.

MPEG++-a robust compression and transport system for digital HDTV
[Proceedings] 1992 IEEE International Symposium on Circuits and Systems, 1992Co-Authors: R. Saint Girons, T. Savatier, S Ng, R Siracusa, Dipankar Raychaudhuri, J. ZdepskiAbstract: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. >
