Abstract

From a computational perspective, it is known that motion compensation and deblocking constitute the two most time consuming components in the video decoding standard. This paper presents a comparison study of the commonly used motion compensation and deblocking filters in terms of the number and type of instructions to indirectly analyze the level of power consumption. Video quality is also taken into consideration as part of this comparison. The comparison results show that the motion compensation and deblocking filters adopted by the H.264 standard provide the highest video quality at the lowest power consumption level for low bit rate video coding applications.
