A digital video signal processing apparatus and method for compensating a chrominance (C) signal includes receiving the C signal separated from an input video signal and compensating the C signal in at least one dimension thereof to generate a compensated C signal. A comparator may determine whether a portion of a Y signal in the input video signal is present in the C signal. The compensator may compensate the C signal only when the comparator determines a portion of the Y signal is present in the C signal. The comparator may calculate a variation between current C data of the input video signal and adjacent C data and compare the variation to a threshold value.
