回路。A VTR television that uses a system in which the VTR adds another vertical synchronization signal (hereinafter referred to as the additional vertical synchronization signal) immediately before the vertical synchronization signal of the recorded signal (hereinafter referred to as the recording vertical synchronization signal) during VTR variable speed mode playback. In the synchronization separation circuit of the receiver, a composite signal including the recording vertical synchronization signal, an additional vertical synchronization signal, and a horizontal synchronization signal, which are the outputs of the normal synchronization and period separation circuit, and a vertical flyback transpulse generated in the vertical output circuit are generated. an additional vertical synchronizing signal, which is the output of the matching circuit, is supplied to a vertical oscillator circuit, and an additional vertical synchronizing signal, which is the output of the anti-coincident circuit, is provided. A synchronous separation circuit characterized in that the other synchronous signal from which the synchronous signal has been erased is supplied to a horizontal AFC circuit.
