264/AVC的可伸缩视频编码（SVC）扩展的性能分析。简要介绍了SVC的主要功能，并概述了编码器控制和比特流提取中的主要问题。率失真优化的SVC的上下文中的一些方面进行了讨论，并提出了相对于调查的可扩展性方案的优化配置的推导策略。基于这些方法，率失真的结果为几个SVC配置，并进行了比较率失真优化的H.264/AVC单层编码。作为参考，提供了与率失真优化的MPEG-4视觉（高级简单简档）编码结果的比较。结果表明，单层编码和可伸缩视频编码之间的性能差距可以非常小，SVC明显优于以前的视频编码技术，如MPEG-4 ASP。
This paper provides a performance analysis of the scalable video coding (SVC) extension of H.264/AVC. A short overview presenting the main functionalities of SVC is given and main issues in encoder control and bit stream extraction are outlined. Some aspects of rate-distortion optimization in the context of SVC are discussed and strategies for derivation of optimized configurations relative to the investigated scalability scenarios are presented. Based on these methods, rate-distortion results for several SVC configurations are presented and compared to rate-distortion optimized H.264/AVC single layer coding. For reference, a comparison to rate-distortion optimized MPEG-4 visual (advanced simple profile) coding results is provided. The results show that the performance gap between single layer coding and scalable video coding can be very small and that SVC clearly outperforms previous video coding technology such as MPEG-4 ASP.
