Abstract :
The formats of the four signals recorded on the high definition optical video disk system are discussed. The first signal is a video carrier FM-modulated with a bandwidth-compressed signal for use in HDTV broadcasting through a satellite. The second is a pilot signal for turntable motor control and jitter compensation. The other two consist of PCM stereo sound, one using time-division and the other frequency-division multiplexing. The resulting disk offers high-definition pictures and high-fidelity sound, and has a playing time of 60 minutes (total for both sides)
