Abstract: This paper describes a method of motion estimation that determines the optimum prediction mode, along with the resulting motion vectors, as a part of the estimation process. It supports all six prediction modes that are allowed by the Main Profile of the MPEG-2 video coding standard, including the dual-prime modes, for frame and field picture types. If implemented on a processor whose architecture is optimized for the required operations, its computational complexity will not be much greater than that of conventional single-mode motion estimation.!3
