Abstract
Method and apparatus for encoding full color video data signals and a protocol for encoding the same in a storage medium. Each pixel of a full color video image is converted into a single 8 bit luminance and multiple 8 bit chrominance components. The 8 bit luminance component is differentially compressed into 5 bits while the chrominance components are subsampled for every four pixels of the video image before being differentially compressed. The differentially compressed subsampled chrominance components and the differentially compressed luminance components are then assembled into a video data signal related to the full color image.
