Abstract

PURPOSE: To obtain good reproduction images by sending out the reproduction TV signal removed of the VTR signal in the vertical flyback time of the video signal from a VTR.
CONSTITUTION: The video signal from a magnetic tape 1 being outputted via reproduction signal processing circuit 2 is passed through a horizontal synchronizing separator circuit, vertical synchroizing separator circuit and pluse forming circuits 7, 10, by which the pulse signals synchronized to the respective synchronizing signals are generated. These signals are inputted to an AND circuit 8, whereby the pulse signals synchronized to the positions and section of the VIR signal are obtained. A gate circuit 3 is driven by the abovementioned signals to remove the VIR signal from the video signal obtained in a processing circuit 2, after which said signal is modulated with a modulator 4 and the reproduction TV signal is sent out from the VTR and is supplied to a TV reciever 5. Since the abovementioned receiver 5 performs the signal processing of conventional system automatically, the image of good quality may be reproduced without the production of skew distortion, etc.
