ABSTRACT:
A video recording/playback system having one or more rotary heads for recording and reproducing a video signal and a fixed head for recording and reproducing a tracking control signal is provided with an enhanced color killer feature. A characteristic of the color killer feature is that a color killer control signal is recorded together with a normal tracking control signal but does not affect the tracking control servo system during signal reproduction. The color killer control signal has a distinguishable characteristic which is detected during signal reproduction and is used to selectively operate a switch included in the usual chrominance signal channel of the recording/playback system.
