ABSTRACT:
Apparatus and method are disclosed for encoding and decoding a video signal. The standard resolution chrominance and the detail component of standard resolution luminance are encoded and transmitted in a way which allows them to be separated at the receiver without cross color. A conventional type of NTSC transmission is modified by adding together the color and the luminance signals above 2.5 megahertz, the information being repeated for two successive frames, with the color carrier reversed in phase as it normally does. At the receiver, successive frames are added and subtracted to recover the color and the luminance above 2.5 megahertz.
