ABSTRACT OF THE DISCLOSURE The method and system for compressing color video data in a video communication system utilizes a three color digital signal, and involves the determina- tion of a luminance function for each pixel in a series of video picture frames. One or more decision parameters based upon differences of the luminance function between pixels are compared with correspond- ing adaptive thresholds to determine decision points in the scan lines, and the digital word size of the three digital color components is reduced before encoding of run lengths between decision points of the color values.
