The digital video encoder or video decoder with referencing frame image compression and decompression mechanism allows a smaller on-chip referencing frame storage device and efficient off-chip referencing frame random access. In using the off-chip frame buffer, a predetermined amount of line buffer temporarily saves the compressed pixels and reconstructs the needed macro-block pixels according to the motion vector for motion compensation in video decoder and reconstructs the searching range pixels for motion estimation in video encoder.
