| 摘 要： | 论述当前的视频转换编码技术，提出一种低复杂度的从H.263到H.264的编码转换结构。该结构基于视频编码中运动估计的残差能量最小的原理，使用自适应能量分类的方法对转换编码进行优化。实验结果显示，该方法相对于H.264全模式搜索能够节省50%以上的时间。与其他快速算法相比，具有较高的编码转换性能。

| Abstract: | This paper discusses the current transcoding, proposes a low complexity transcoding structure from H.263 to H.264. The method is based on the principle of the minimum residual energy of motion estimation. Adaptive energy method is layered to reduce the time of inter-frame prediction modes selection on re-motion estimation. Experimental results show that compared with full modes search method, it can save more than 50% of the time. With other fast transcoding algorithms, the method has lower complexity, higher video quality, and a shorter time transcoding. |
