Abstract
The DigiCipher high-definition television (HDTV) system, an all-digital approach that achieves full HDTV performance with error-free reception in a single 6-MHz television channel is described. The DigiCipher HDTV system is based on discrete cosine transform coding and uses motion prediction techniques to eliminate redundancy in the digital signal, channel equalization to defeat multipath, and error correction to defeat noise and interference. The source signal, source coding, channel coding, modulation, and performance of the system are discussed
