Abstract
Selected fields of a redundant field slow motion video tape reproduced video signal are stored in a memory at a given clock rate and recovered from the memory at a clock rate inversely proportional to the number of times each field is repeated so as to produce a non-redundant video output signal of reduced bandwidth yet processing the full informational content of the original video signal. The original signal normally exhibits an ordered color field sequence but is subject to anomalous variations from time to time which causes anomalous variation of the chrominance-burst phase relationship of the video output signal. A detector, responsive to a change of a parameter of the video input signal, detects the anomalous variations of the chrominance-burst phase relationship and produces a control signal that is applied to a circuit which effectively reverses the phase relationship of the chrominance and color burst components of the video output signal of the memory when the control signal is present.
