Abstract
A high definition television system that is characterized by low transmission bandwidth is achieved by removing much of the redundancies in the signal, efficiently encoding the remaining signals, and transmitting the encoded signal in a manner that is most compatible with the applicable standards. To enhance noise immunity a number of techniques are employed. One is to encode adjacent low-amplitude signals into larger signal samples, another one is the introduction of a controllable gain feature, a third one is the introduction of both fixed and variable leak, and still another one is the incorporation of signal scrambling.
