ABSTRACT:
A high definition television transmitting system includes a source of high definition analog RGB video signals which are converted to corresponding digitally encoded signals and thereafter compressed by a video encoder to a six megahertz bandwidth. The compressed data is formatted by a transmitter and processed in accordance with a Reed-Solomon error control system for broadcast as an NTSC-type broadcast signal. A high definition television receiver includes a high definition signal receiver coupled to the transmitter by a transmission link. The receiver extracts the compressed video, audio and ancillary data signals and applies a Reed-Solomon error correction thereto. The compressed video data is reconstructed by a video decoder and processed for high definition display. A high definition digital video tape recorder is coupled to the transmitter by an interface and format converter facilitating both recording and playback functions of the digital video tape recorder while maintaining the Reed-Solomon error control. The format converter provides compatibility between the high definition transmitter and the digital video tape recorder.
