Abstract
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.
