摘要

在分析最新的视频编码标准H.264与以前的编码标准差异基础上

针对压缩域的H.264视频转码

系统地研究了其关键技术的进展

并按DCT到HT的系数变换、运动矢量快速重估计、修正和帧内/间编码模式和速率控制等4个方面进行了分类归纳

还对未来本领域值得研究的问题进行了展望和预测。

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.
