Abstract

This paper provides a technical overview of the prioritization and transport in the Advanced Digital Television system (ADTV). ADTV is the all-digital terrestrial simulcast system developed by the Advanced Television Research Consortium, ATRC, (Thomson Consumer Electronics, Philips North America, NBC, Compression Labs, and the David Sarnoff Research Center.) 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 1440x960 (10 50-line 2:1 interlaced) HDTV format, producing a selectable bit-rate in the region of 15–20 Mbps. The data prioritization layer of ADTV 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 prioritized 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. (Issues related to the ADTV compression coding, receiver error recovery, and transmission are discussed in separate papers.[1,2,3])
