ABSTRACT OF THE DISCLOSURE In reproducing chrominance signal components of com- posite color video signals recorded on a record medium in a form of parallel tracks with different carrier frequencies having interleaving relations therebetween, there are disposed a switch circuit and a comb-filter for cancelling the cross- talk components of chrominance signals reproduced from adjacent tracks. The switching actions of the switch circuit are con- trolled by phases of the resultant chrominance signals for phase alignment during entire reproduction of the chrominance signals.
