Method of block partition for h.264 inter prediction

Abstract

Provided is a method for partitioning a block in inter prediction including selecting one standard reference frame from at least one reference frame which is a comparison target in inter prediction, searching whether or not a higher-level macroblock of a current frame is partitioned based on the selected standard reference frame, determining a partition size of the higher-level macroblock of the current frame, searching whether or not the higher-level macroblock in which the partition size is determined is partitioned by comparing with any certain reference frame other than the standard reference frame, and stopping a block size search on the higher-level macroblock of the current frame if a partition size of the higher-level macroblock of the current frame determined by comparing with the standard reference frame and a partition size of the higher-level macroblock of the current frame determined by comparing with the certain reference frame are different from each other.
