Motion and Mode Mapping for MPEG-2 to H.264/AVC Transcoding
This paper describes novel low-complexity transcoding techniques for an efficient MPEG-2 to H.264/AVC transcoder. We present a motion and mode mapping algorithm that directly maps incoming MPEG-2 motion information to H.264/AVC motion vectors as well as coding modes. Refinement strategies are also presented to improve performance. Experiment results demonstrate the effectiveness of the proposed low-complexity transcoder
