Abstract
A television video signal is compressed to the number of digital video signals sufficient for display of an image on a liquid crystal display. A television audio signal is also sampled and digitized. The television video and audio signals are combined to produce a digital television signal. The audio signal is sampled and digitized to produce the digital audio signal. The rotational speed of a rotary drum having record/playback heads in the digital television signal record/playback mode is different from that in the digital audio signal record/playback mode. By utilizing a digital audio tape recorder (DAT), the digital television and audio signals can be selectively recorded or played back.
