Abstract

PURPOSE:To prevent the disturbance of vertical synchronism at the joint of scene, by generating a spurious vertical synchronizing signal which synchronizes with the rotation of a capstan in reproduction and is equal phase to a vertical synchronizing signal contained in a reproduced signal. CONSTITUTION:Output I of carrier detecting circuit 25 is at ''0'' in a nonsignal section and at ''1'' at normal recording parts of both sides of it. Vertical synchronizing signal H separated from video signal G by vertical-synchronizing-signal separating circuit 27 becomes a reset input of (n)-notation counter 22, in which outputs synchronizing signal B is outputted. On the other hand, even if signal H is not generated in the nonsignal section, synchronizing signal B is outputted which corresponds to the extent of the rotational displacement of capstan motor 16. This signal B is made into signal J by monostable multivibrator 28. At the normal recording part, switch circuit 26 is placed at side N to send signal G as input signal K to TV receiver 10, and at the nonsignal part where the output of circuit 25 ''0'', circuit 26 is changed over to side BL to substitute signal J for signal K. Therefore, the synchronism in the side of image receiver 10 never deviates even in the nonsignal section.
