Transcoding of H.264 Bitstream to AVS Bitstream

This paper proposes a transcoding scheme from H.264 to AVS. As the highest performance video coding standard, H.264 is developed by MPEG and ITU, AVS is developed by the Audio Video Coding Standard Working Group of China. The two standards will co-exist in the future application, therefore, it is worthy to transcode the video format from the H.264 to AVS and almost no complete research on this scheme until now. This paper proposes an effective transcoding method to achieve high efficient and fast transcoding without losing much quality by reusing intra mode, inter mode, motion vector and SAD, etc. Detailed experiment results demonstrate that the proposed algorithm can effectively reduce the transcoding complexity.
