Abstract

PURPOSE: To eliminate the time axial fluctuation component in the carrier chrominance signal by obtaining the signal containing the velocity error component through the phase comparison between the burst signal and the continuous wave signal right before the burst signal in order to produce the conversion signal and then giving the frequency conversion to the carrier chrominance signal by the conversion signal.
CONSTITUTION: Continuous wave signal formation circuit 30 forms the continuous wave signal possessing the time axial error contained in the burst signal in the carrier chrominance signal. And the phase comparison is given between the burst signal and the continuous wave signal right before the burst signal through detector circuit 35 to obtain the signal possessing the velocity error component. Based on the velocity error, the phase modulation is given to the refernce signal via phase modulator circuit 34. Then the carrier chrominance signal receives frequency conversion 31 by the phase-moldulated signal and the continuous wave signal. As a result, the time axial fluctuation component contained in the carrier chrominance signal can be eliminated.
