Abstract
A television system for broadcasting high definition television on two channels of a direct broadcast satellite, a first of which carries a compatible 525-line picture. A second channel carries an augmentation signal, which in conjunction with the signal from the first channel, produces at a receiver tuned to both channels a 1050-line high definition television picture with a 5:3 aspect ratio. Time multiplex component signals and processing are employed, and high fidelity sound is provided by digital audio signals transmitted in time sequence with the video. There may be as many as five sound channels so as to provide three-channel stereophonic audio and various combinations of data and sound channels.
