H.264/AVC multiple reference video frames

H.264/AVC standard for video coding uses multiple reference frames to enhance the coding efficiency. The quantity of increased computation is linearly proportional to the number of reference frames. This paper proposed the motion estimation of the multi macroblocks, taking into account the low complexity and fast multiple reference selection method. The simulation results show that the speed of the proposed method is over two times faster than that of the original scheme adopted in reference software, while keeping the similar video quality and bitrate.
