Abstract

The Motion Compensation technique and Discrete Cosine Transform are used in the standardized moving image coding method MPEG. In the Motion Compensation, an image is divided into macroblocks, and the macroblosk size of 16x16 pixels is used in the MPEG2, and 16x16 to 4x4 pixels in H.264/MPEG4-AVC. However, when the Motion Compensation is applied to the high definition videos, the size that is larger than 16x16 pixels might become efficient. In this paper, we examined the suitable macroblock size in the Motion Compensation to the high definition videos.
