Abstract	AVS-M (the advanced audio video coding standard-mobile version) is established by Audio Video Standard Working Group of China for mobile-multimedia applications. To meet demands for communication between multimedia source and mobile system, transcoding from MPEG-2 to AVS-M is a key technique. However, the advanced intra and inter mode decision techniques adopted in AVS-M have a high computing requirement, which limits the real time implementation in mobile environment. In this paper, we propose a prediction mode decision optimization algorithm to reduce the transcoding complexity based on our previous work. Analyzing the relation among the prediction errors of blocks and doing adaptive motion re-estimation, we fast decide the best inter mode. Utilizing the directional feature of DCT coefficients, we fast decide the best intra mode. The simulation results show that the proposed MPEG-2 to AVS-M transcoder with mode decision optimization can be effectively adopted for mobile video communications
