Abstract :
Video transcoding has been a critical issue in order to make the multimedia contents available for different systems under various environments. In this paper, a dedicated transcoder from AVS to H.264/AVC with reduced resolution is proposed, aiming to provide a fast and reliable solution for transcoding standard-definition videos to mobile contents. A multi-stage process is introduced for accurate motion and mode mapping. Through this process, huge computation time saving can be achieved with only negligible quality degradation.
