Source coding, channel coding and modulation techniques used in the ATVA-progressive system
J.A. Krauss · IEEE Transactions on Broadcasting · 1991
The ATVA-progressive system, an all-digital high-definition television system that delivers very high quality pictures to the home within a 6-MHz channel in the presence of noise, ghosts, and frequency distortion is described. The system achieves a high degree of data compression by means of motion compensation and transform/subband coding, and only transform/subband coefficients with significant energy are transmitted. For terrestrial transmission, an all-digital format that uses a single carrier with double sideband suppressed carrier quadrature modulation is used. The source signal, source coding, channel coding, modulation, and performance of the system are discussed.>
