Abstract
PURPOSE:To stabilize a color killer operation and to eliminate a synchronizing interference by a color noise by setting the larger gate period of a reproducing gate circuit by a prescribed period than that of a recording gate circuit. CONSTITUTION:In a gate pulse generating circuit 22 for determining the gate period of the recording gate circuit 7 and the reproducing gate circuit 18, a signal delay period by two monostable multivibrators 23, 24 for respectively forming the leading edge part and the trailing edge part of a gate pulse is switched at the time of recording and at the time of reproducing. The gate pulse generated by a gate pulse generating circuit 27 is larger by the prescribed period at the time of the recording reproduction than that at the time of the recording. Accordingly, a signal which is not contaminated by the color noise is not removed but left in a recording system and the color noise accumulated in a process for a chrominance signal processing can be completely removed. Thereby, the color killer operation is stabilized to prevent the synchronizing interference due to the color noise.
