ABSTRACT:
Digest playback apparatus and method for a VCR. The digest playback apparatus includes a system controller for outputting a plurality of control signals to control the entire operation of a video cassette recorder system, the plurality of control signals including speed-change multispeed and direction data and audio multispeed change mode ON/OFF data. An analog/digital conversion circuit converts an analog audio signal read by an audio head and then restored to its original state into digital audio data regardless of a speed-change mode. A memory stores the digital audio data from the analog/digital conversion circuit. A digital/analog conversion circuit converts the digital audio data stored in the memory into an analog audio signal, and a control circuit controls the analog/digital conversion circuit, the memory and the digital/analog conversion circuit to output the analog audio signal from the digital/analog conversion circuit as a 1 multispeed which allows the user to accurately listen to the output analog audio signal.
