Abstract

A communication-theoretical model adapted to ATV (advanced television) and HDTV (high definition television) systems, partitioned into functional blocks to which performance criteria and theoretical limits can be applied, is briefly described. The types of signal processing which are or could be employed in each block to decrease the effects of channel degradations are described for both analog and digital transmission, with primary emphasis on analog transmission for terrestrial broadcast. Digital transmission over these channels is treated briefly. Analog and digital transmission over satellite and fiber optic channels is summarized. New signal processing functions are discussed
