MOTION SEARCH MODULE WITH HORIZONTAL COMPRESSION PREPROCESSING AND METHODS FOR USE THEREWITH

A motion compensation module, that can be used in a video encoder for encoding a video input signal, includes a motion search module that generates a motion search motion vector for each motion search macroblock of a plurality of motion search macroblocks in at least one of a horizontally compressed and vertically uncompressed field of the video input signal and a horizontally compressed and vertically uncompressed frame of the video input signal. A motion refinement module generates a refined motion vector for each motion refinement macroblock of a plurality of macroblocks of at least one of an uncompressed field of the video input signal and an uncompressed frame of the video input signal, based on the motion search motion vector.
