Video transcoding for H.264 in the compressed domain and key techniques analysis
Abstract
Based on the analysis of the difference between the newest video coding standard H.264 and the earlier video-coding standard,the advances in the key technologies for H.264 video transcoding,which was directly conducted in the compressed domain,were systematically discussed.They were classified into four categories: DCT-to-HT coeffi-cients conversion,fast motion re-estimation and refinement,inter/intra coding mode decision and rate control.Future di-rections on this topic were also prospected.
