ABSTRACT:
A video signal processing system including a reproducing or receiving circuit which is responsive to a recorded or transmitted video signal having a motion signal modulated at a first frequency mixed with a chroma signal modulated at a second frequency, wherein the reproducing or receiving circuit includes a chroma/motion C/M separating circuit for separating the motion signal from the chroma signal, and a vertical low-pass filter for passing vertical low frequency components and removing vertical high frequency components to eliminate redundant components existing in the vertical high frequency component of the video signal. The system can be adapted to any video system which carries out three-dimensional video processing, using a motion signal, to enhance high resolution.
