This paper describes novel motion mapping algorithms aimed for low-complexity MPEG-2 to AVC transcoding. The proposed algorithms efficiently map incoming MPEG-2 motion vectors to outgoing AVC motion vectors regardless of the block sizes that the motion vectors correspond to. Extensive simulation results show that our proposed transcoder incorporating the proposed algorithms achieves very good rate-distortion performance with low complexity. Compared with the cascaded decoder-encoder solution, the proposed approach could achieve similar coding efficiency while significantly reduce the complexity.
