Abstract :
Summary form only given. The ATSC (Advanced Television Systems Committee) digital television system (DTV) will soon be a reality in the United States. While the FCC has not specified the resolution of the transmitted video, it is expected that most broadcasters will move rapidly towards the flagship application of DTV, namely high definition television (HDTV). The introduction of a DTV/HDTV system must meet the difficult challenge of coexisting with currently operating analog television services. Based on the nature of today´s analog television transmission, only every other VHF channel and every sixth UHF channel are assigned as full power services in any given city. There are about 1600 full power stations in the USA, plus about 6000 full power translator/repeaters (mostly in the sparsely populated western US). The digital vestigial sideband (VSB) system was chosen, after extensive competitive testing, to be the transmission (or modulation) technology for the ATSC system. The 8-level PAM (8-VSB) system meets all the requirements
