RCA 73,687 Abstract A defect compensation circuit of the type that substitutes a portion of delayed signal information for a real-time signal defect including circuitry for correcting chrominance phase reversal. The delayed signal is sampled at 1/2 the period of the chrominance before and after a 1H delay. The signal samples are summed and proportioned to provide a substitution signal having its chrominance signal in phase with the real time signal, and an average luminance signal exhibiting non-observable distortion.
