Abstract
A control circuit for video tape recording and/or playback apparatus is coupled to a stationary control head for selectively changing the duty ratio of the control signal that accompanies the recorded video signal and is the same signal that is used to control the servo operation of head drum and capstan motors of the apparatus. Normally, the duty ratio of the control signal is 50%, but the control circuit permits an operator to selectively alter the duty ratio, for example, to 30%, to indicate that the accompanying segment of the recorded video signal is to be edited out, that is, skipped over when the tape is played back. A duty-ratio detector coupled to the control head discriminates the duty ratio of the reproduced control signal, and a system controller automatically changes the mode of the apparatus to advance at fast-forward past those portions of the video signal accompanied by a 30%-duty-ratio control signal.
