Abstract

PURPOSE:To improve the resolution of a reproduced picture, by using effectively high-band components of the luminance signal included in the signal of the chrominance signal band. CONSTITUTION:The composite color video signal applied to an input terminal 1 is supplied to a horizontal synchronizing separator 22 also, and the horizontal synchronizing signal separated there is supplied to a phase comparator 23. A local oscillator 7' which oscillates a local signal for frequency conversion is constituted as a voltage control oscillator, and the output is supplied to not only a frequency converter 6 but also a 1/n frequency divider 24. The signal of the frequency divider 24 is compared in phase with the horizontal synchronizing signal by the phase comparator 23, and the oscillation of the local oscillator 7' is controlled by the error signal. Thus, the frequency converted signal has a constant phase relation to the composite color video signal.
