Abstract :
In this paper we present an original motion compensation strategy based on frame partitioning. The proposed method uses different temporal resolutions within a frame to improve compression. We present a new bit allocation and rate control algorithm complementing our motion compensation technique. This unique approach to bit allocation ensures the consistency of quality throughout a single frame and a GOP. For the same picture quality, frame partitioning alone yields an additional increase of up to 20 percent or more of the encoding efficiency
