Abstract
A motion compensation module can be used in a video encoder for encoding a video input signal that includes a sequence of images are segmented into a plurality of macroblocks. The motion compensation module includes a motion search module, that generates a motion search motion vector for a plurality of subblocks for a plurality of partitionings of a macroblock of a plurality of macroblocks. A motion refinement module generates a refined motion vector for the plurality of subblocks for the plurality of partitionings of the macroblock of the plurality of macroblocks, based on the motion search motion vector for each of the plurality of subblocks of the macroblock of the plurality of macroblocks. The motion refinement module can operate in a plurality of selected modes including a first mode corresponding to a first sub-pixel resolution and a second mode corresponding to a second sub-pixel resolution.
