Abstract
Efficient motion re-estimation schemes for H.264 Band P-frame transcoding are proposed in this paper. The proposed methods compose new motion vectors for out-going video bitstream from the pre-coded bitstream by utilizing Maximum Likelihood. The experimental results show that the proposed method can improve the performance and efficiency compared to previous approaches.
