Abstract
In a record mode, a record video signal applied to an input terminal is separated into a luminance signal and a color signal by a comb filter made up of a 1H delay line, an adder circuit and a subtraction circuit. In a playback mode, the reproduced luminance signal and color signal are added together in an adder circuit, thereby to form a video signal. This video signal is applied to the comb filter through switches and then is separated into a luminance signal and a color signal.
