| 摘 要： | H.264/SVC(Scalable Video Coding)使用了多种预测编码机制,极大地提高了分级编码的编码性能,同时也引入了复杂的编码依赖关系,给编码器的优化控制带来了极大的难度。因此,有必要研究这种不可忽视的编码依赖关系。在介绍H.264/SVC的主要预测编码机制的基础上,分析归纳出H.264/SVC的编码依赖关系主要来源于帧间预测、层间帧内预测和层间残差预测,然后针对这三种预测机制的特点,结合文献1]提出的帧间依赖关系,基于实验数据,建立了编码依赖模型,得到了用编码依赖测度表达的编码依赖关系。最后,将时域依赖模型应用到H.264/SVC基本层码率控制中,实验数据表明时域依赖模型能够提高码率控制的性能。

| Abstract: | With various predictive coding mechanisms in H.264/SVC (Scalable Video Coding), significant improvements of the coding performance were demonstrated in SVC, and at the same time the complex coding dependence relation was introduced. It is very difficult to optimize encoder control, and necessary to research this relation. Based on the introduction of the main predictive coding mechanisms in H.264/SVC, it is concluded that coding dependence mainly comes from inter-frame prediction, inter-layer intra predicti... |
