Abstract :
The digital spectrum-compatible high-definition television (DSC-HDTV) system, a digital HDTV simulcast system designed for United States terrestrial broadcasting on currently unassignable channels, is described. The system uses progressively scanned source signals and is characterized by an effective, high-performance video compression system. Compression includes motion compensation with hierarchical block matching and block transform coding with adaptive quantization according to perceptual criteria. Video compression is designed to simplify the receiver decoding; only a few VLSI chips and only one full frame memory are required. The source signal, source coding, channel coding, modulation, and performance of the system are discussed
