Description

ABSTRACT:
A data regenerating circuit is included in a video disk recording and playback systems in which the video disk is controlled in a desired mode in response to selected digital control data contained in the vertical blanking intervals of a recorded video signal. The circuit includes a random noise detector for detecting noise that might occur in the vertical blanking interval to prevent the control system from operating the disk in an undesired mode.
