ABSTRACT OF THE DISCLOSURE In an apparatus for processing reproduced color video signals composed of a frequency-modulated luminance component and a frequency substantially below a standard frequency therefor; there are provided a drop-out compensating circuit responsive to a drop-out in the luminance component for inserting, in the interval of such drop-out, an earlier occurring portion of the luminance component, a frequency- converter receiving the chrominance component and a frequency- reconverting signal for restoring the carrier frequency to the standard frequency therefor, an automatic frequency control circuit (AFC) responsive to horizontal synchronizing signals separated from the luminance component after the drop-out compensation thereof so as to regulate the frequency- reconverting signal in the sense for removing time base errors from the reproduced color video signals, and a circuit which is responsive to a drop-out in the luminance component for maintaining the frequency of the frequency-reconverting signal at a previously determined value during the drop-out so that the automatic frequency control operation will not be adversely affected by the drop-out compensation.
