Abstract: By relaying on a temporal correlation among successive pictures beside on a spatial correlation of motion vectors of macroblocks of the currently processed picture and by the use of a hierarchical recursive motion estimation algorithm, the hardware complexity of video coders complying with the MPEG-2 standard can be greatly reduced without an appreciable loss of quality of the video images been transferred. The method of motion estimation and a hardware embodiment of a coder are described and performance is compared with a prior motion estimation system.
