Abstract

PURPOSE:To prevent unnecessary recording of a VTR by detecting the interruption of the video input signal, and stopping the recording of a video signal through a shutting-off circuit. CONSTITUTION:When a detecting circuit 6 detects the interruption of a video input signal containing a vertical and a horizontal synchronizing signals from a video signal circuit 5, a shutting-off circuit 7 generates a shut-off signal. This signal stops the video signal recording operation of a VTR and thus unnecessary recording of the VTR is prevented, so that a video tape is used effectively.
