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.

Abstract: A linear gain differential amplifier having feedback stabilization which is capable of providing inverted and noninverted outputs of equal amplitude is disclosed. A pair of coupled voltage following, feedback stabilized amplifier circuits provide a differential output which is a function of only the respective input signals and the passive component values in the circuit. The present invention is capable of operating at high frequencies over a wide bandwidth and is particularly adapted for video signal processing where linear gain, DC stability, phase compensation and high frequency response are required in order to prevent video luminance and chrominance fluctuations caused by differential gain and phase distortion.
