Abstract

PURPOSE:To apply a TBC even at the time of a video signal having no color bursting signal by switching a signal equivalent to the synchronizing signal part of a modulated video signal to a reference frequency signal with a switching means. CONSTITUTION:For a change-over switch 20, the said change-over switch 20 is connected to an H side only the period equivalent to a think chip in accordance with a pulse generated by a timing pulse generating device 34. The output of a phase comparator 24 through a switch 22 is integrated by a loop filter 20 and an error signal to give a prescribed phase compensation is sent to the converting range input of a frequency modulator 14. By a PLL loop formed in the sequence of the frequency modulator(MOD) 14 a counter 16... the phase comparator 24 the switch 22 LPF 20 the frequency modulator(MOD) 14, the frequency signal of the think chip of a signal modulated by an FM modulator 16 is exchanged and outputted with the reference signal of the prescribed frequency generated from a reference signal generating device 26.
