A video signal dropout compensator stores information from at least one incoming television line which is represented by a plurality of samples of combined liminance and chrominance signal components. The samples occur at a rate equal to four times the chrominance subcarrier frequency. When a signal dropout is detected in one or more of the samples, a replacement sample is generated using samples from at least one adjacent television line. The value of the sample on the adjacent line at the horizontal location, corresponding to the dropout sample, is subtracted from the sum of the samples before and after this corresponding location sample. The resultant value gives a dropout replacement sample with proper chrominance phase having a close approximation of the correct luminance value.
