Title:
VIDEO SIGNAL PROCESSOR
Document Type and Number:
WIPO Patent Application WO/1986/004760
Kind Code:
A1
Abstract:
A video signal processor used for a recording/reproducing apparatus such as a video tape recorder that includes decoder (36) and encoder (16), or an apparatus for transmitting video signals. The video signal processor divides a composite video signal into a luminance signal and two chrominance signals. At the time of decoding, the video signal processor transmits data signals that indicate the phase of chrominance sub-carrier waves in the composite video signals. At the time of encoding, the video signal processor controls the relation of phase between the composite video signals and the chrominance sub-carrier waves relying upon the data signals, so that the high level of the luminance signal and the chrominance signals have no distortions or minimum ones.
