Method and system for compressing and statistically encoding color video data |
摘要 |
The method and system of compressing digital color video data in a video communication system utilizes a digital color video signal having three video color components, and the encoding of the color components as compressed color codes in a series of run length and compressed color code combinations. A look up table of compressed color codes representing the most visually significant combinations of three color components may also be modified by a process which involves the determination of a predetermined number of the most visually significant combinations of color components in a picture frame. Line-to-line differences and movement of edges and segments of the picture frames are determined, and frame-to-frame differences are also encoded to reduce the amount of information to a minimum. Further statistical encoding of at least a portion of the run length and color code combinations is also provided.
