摘要： A time-base error correction system for a video signal employing a plurality of serially connected delay lines. Circuit means are conditioned to detect the closest timing match between a reference synchronizing signal and the video signal as it appears at various points along the delay path and to connect the appropriate delay line point or junction to an output at which the correctly delayed video signal appears. Featured circuitry provides for eliminating the erroneous leading edge of a video synchronizing pulse distorted by changes in the selected delay point and for compensating for variations in d.c. offset of the video signal introduced by differential delay line path effects.
