Abstract
A motion refinement engine can be used in a video encoder for encoding a video input signal that includes a sequence of images that are segmented into a plurality of macroblocks. The motion refinement engine includes a motion search module, that generates at least one motion search motion vector for a macroblock of the plurality of macroblocks based on a first plurality of directions. A motion refinement module generates at least one refined motion vector for the macroblock of the plurality of macroblocks, based on a second plurality of directions, wherein the second plurality of directions differ from the first plurality of directions. In a further embodiment, motion search, motion refinement, and motion compensation are selectively performed in a single pass.
