Zusammenfassung:PURPOSE:To permit fast reproductions or inversion fast reproduction without generating skews by setting synchronous signals at a constant interval after using variable delaying means which control delay times through digital- processing. CONSTITUTION:In case of a fast reproduction, a output of a video signal demodulation circuit 35 is converted into digital signals through an A/D converter 40 and a horizontal synchronous signal is detected by a horizontal synchronous separating circuit 41. And a digitized signal is inputted in a variable delay circuit 42 by a converter 40 and at the circuit 42, a delay time is determined on the basis of a changeover signal through an envelop comparison circuits 38 as well as the horizontal synchronous signal from the circuits 41 and then the above digitized signals allow the signals from the converter 40 to be delayed. Thus, the signal in which horizontal synchronous signals have the constant intervals and the skews are corrected, are converted into an analog signal by a D/A converter 43 and will be output from a terminal 36. In other words, the fast reproduction as well as inversion fast reproduction can be corrected without skew.
