Abstract

A television synchronization signal processing circuit includes a reproduction/demodulation circuit for reproducing a video signal by repeatedly reading out a video signal for one field from a video signal recording medium, generating the reproduced video signal and a synchronization signal separated from the reproduced video signal, a first delay circuit for delaying the reproduced video signal read out for every other field from the reproduction/demodulation circuit by one half a period of the horizontal synchronization signal, signal transmitting circuit for transmitting a vertical synchronization signal included in the separated synchronization signal from the reproduction/demodulation circuit, and waveform synthesis circuit for synthesizing output signals from the first delay circuit and signal transmitting circuit to produce a composite video signal used for effecting video display. The signal transmitting circuit includes a second display circuit for delaying the vertical synchronization signal by a predetermined period of time shorter than one half the period of the horizontal synchronization signal.
