Abstract
PURPOSE: To ensure the steady output of the reproduced carrier signal with no uneven color nor the color lack by varying the reproduced carrier signal relatively by the fixed phase via the output of the phase detector which generates the control signal the burst signal phase is within a fixed range.
CONSTITUTION: Frequency conversion 19 is given to the reproduced low-band conversion carrier chrominance signal via the signal whose phase differs in sequence and in such relation in that the desired carrier chrominance signal phase may be obtained, and then the reproduced carrier signal is obtained through comb-line filter 23. Then the burst signal phase of the reproduced carrier chrominance signal undergoes phase detection 30, and the reproduced carrier chrominance signal is varied by the fixed phase relatively by the output of phase detector 30 which produces control signal PI when the burst signal phase is within a fixed range. In this way, the steady output is ensured for the reproduced video signal with no uneven color nor the lack of the color.
