ABSTRACT:
A video signal processing apparatus has a phase-locked loop which includes a quartz resonator, a voltage-controlled oscillator connected to the quartz resonator and oscillating at an oscillation frequency whose fundamental value is determined by the quartz resonator, and a horizontal sync signal lock circuit comparing a phase of a horizontal sync signal and a phase of an output signal from the voltage-controlled oscillator and controlling the oscillation frequency of the voltage-controlled oscillator in response to a difference between the phases of the horizontal sync signal and the output signal from the voltage-controlled oscillator. The video signal processing apparatus also has a device for modulating a video signal by use of the output signal from the voltage-controlled oscillator.
