Abstract

PURPOSE: To obtain a burst signal with neither phase distortion nor waveform distortion by substituting a burst signal in a chrominance signal separated from a reproduced color video signal by a new burst signal generated from a reference signal from a reference signal generator.
CONSTITUTION: A reproduced color video signal is supplied to HPF2 and LPF3. A luminance signal is obtained from HPF2 and supplied to mixer 6 by way of FM demodulator 4 and LPF5. From LPF3, a low-frequency converted chrominance signal is supplied to frequency converter circuit 8 and BPF9, which output a power- inverted chrominance signal. A burst signal in this chrominance signal is substituted by switch circuit 10 by a burst signal generated newly from a reference signal from reference signal generator 13. Namely, the output of reference signal generator 13 is supplied to one fixed contact of switch circuit 10 by way of burst gate circuit 14 and the output of BPF9 is to the other fixed contact. Then, the output of circuit 10 is supplied to mixer 6, where it is added to a luminance signal to obtain a NTSC color video signal.
