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.

Digest playback apparatus and method for video cassette recorder

A digest variable speed reproducing apparatus for a video cassette recorder (VCR) including a system controller for supplying a desired variable speed data; a control signal detector for detecting a control signal written onto a VCR tape together with an audio signal during digest variable speed reproduction, from the VCR tape; a variable speed controller for supplying A/D conversion execution signal and D/A conversion execution signal and for supplying write control signal or read control signal only when a control pulse is detected by the control signal detector, in response to the variable data from the system controller; an A/D converter for converting a reproduced analog audio signal into a digital signal with a sampling rate corresponding to the variable speed data in response to the A/D conversion execution signal; a D/A converter for reconverting the digital signal read from a memory into an analog audio signal in response to the D/A conversion execution signal; and a memory for writing variable speed digital audio data output from A/D converter by a write control signal, or for reading digital audio data written by a read control signal at a speed prior to variable speed, thereby supplying the data to D/A converter.
