ABSTRACT:
Apparatus for use with a video signal playback system of the type which reproduces a previously recorded composite color video signal wherein time-base errors appear in the luminance component of that video signal. The apparatus modifies the chrominance component of the composite video signal so as to have time-base errors in correspondence with the errors in the luminance component. The luminance and chrominance components are separated from the composite color video signal; and a local subcarrier reference signal is generated to have the time-base errors which are present in the luminance component. This local subcarrier reference signal is essentially substituted for the subcarrier of the reproduced chrominance component, thereby imparting such time-base errors into the chrominance component. At least the chrominance component is delayed by an amount equal to a horizontal line interval so as to equalize the time-base errors which have been imparted into the chrominance component with those time-base errors which are contained in the reproduced luminance component. The delayed luminance component and the substituted-subcarrier chrominance component are combined so as to reform the composite color video signal.
