Abstract

PURPOSE: To define a picture on a screen by comparing a horizontal synchronizing pulse with an oscillation frequency twice the horizontal frequency and by outputting a false signal by using the detection output as a control signal while the horizontal synchronizing pulse of a regenerated viadeo signal shifts in phase.
CONSTITUTION: Regenerated putput signal Sf from amplifier 12 is enveloped-detected 21 and a signal indicating the level of signal Sf is supplied to waveform-shaping circuit 22. With the level of signal Sf below a fixed value, signal St is generated which becomes "0" at a certain time, and a signal after blacking 37 is applied to adder circuit 38. Horizontal synchronizing pulse Ph after horizontal synchronous separation 31, on the other hand, is sent to comparator 31, where it is compared with oscillation signal So of a frequency twice the horizontal frequency of voltage control oscillator 33, and the detection output is supplied as a control signal to oscillator 33. While a video signal regenerated by this detection signal shifts in phase, a false signal is outputted as a substitute for the regenerated signal, thereby defining a regenerated picture.
