Abstract
A scaled motion search section can be used in a video processing device that processes a video input signal that includes a plurality of pictures. The scaled motion search section includes a downscaling module that downscales the plurality of pictures to generate a plurality of downscaled pictures. A reduced-scale motion search module generates a plurality of motion vector candidates at a downscaled resolution, based on the plurality of downscaled pictures. The reduced-scale motion search module includes a column buffer that stores a column of reference data and generates the plurality of motion vector candidates based on a parallel processing of the column of reference data for a group of adjacent macroblock pairs.
