【摘要】 H．264因其优越的编码效率和良好的网络适用能力已经成为最新的国际视频编码标准,并且被誉为适用于视频广播的最优的编码器。目前,人们提出了将可伸缩编码技术引入到H．264编码标准中,以解决网络拥塞和带宽波动的问题。其中精细颗粒可伸缩编码作为一套可行的方案被引入到H．264编码标准中。本文在H．264可伸缩编码参考模型JSVM(Joint Scalable Video Model)的基础上,提出了一种精细颗粒可伸缩编码算法,对JSVM模型做了必要的改进。最后对所提出的算法进行仿真,并分析了其性能。更多还原

【Abstract】 H.264, with its superior coding efficiency and network friendly design, has emerged as the newest video standard and is expected to become the preferred codec for video broadcasting. Presently, there is an effort to add scalable video coding to H.264, in order to solute offer a solution to network congestion and bandwidth variations. FGS, as a feasible scheme, was introduced to the H.264 standard. This paper, based on the JSVM (Joint Scalable Video Model), proposed a new FGS arithmetic, made some necessary improvement to JSVM. At last, analyses it’s performance via debugging the encoder.更多还原
