Abstract
PURPOSE: To reproduce an excellent picture by reducing the jitters and color blurs on a picture caused by compensating, by eliminating the disorder of color demodulation by compensating the line consecutiveness of reproduced chroma signals when getting disorder.
CONSTITUTION: Frame still reproduced signal VIDEO from VTR is supplied to 1H delay circuit 1 to delay luminance signal Y and chroma signal C by 1H and the output of circuit 1 is supplied to Y/C separator circuit 2 to obtain separated luminance signal Yn-1 and chroma signal Cn-1. This signals Yn-1 and Cn-1 are mixed by mixer 5 and obtained signal Yn-1+Cn-1 is supplied to the (b) contact terminal of switch circuit 6. On the other hand, signal VIDEO is applied to Y/C separator circuit 3 to separate chroma signal Cn, which is mixed with signal Yn-1 delayed from circuit 2 by mixer 4 to apply signal Yn-1+Cn to the (a) contact terminal of circuit 6. This circuit 6 is controlled by frame pulses and a signal with the line sequence of chroma signals compensated is outputted to the output of circuit 6.
