H.263+部分可选模式的研究

A Study of H.263+ and its Several Negotiable Modes

在阐述了 ITU- T H.2 6 3“低码率图像通信”国际标准及其编码可选模式的基础上 ,详细讨论了 H.2 6 3Version 2 (H.2 6 3+)及其 3种可选模式的编码机理 .最后 ,通过计算机对比实验证实了 H.2 6 3+可提高压缩性能 ,并讨论了 3种可选模式的复杂度。

After a description of the International Standard ITU T H.263 'Low Bit Rate Video Communication', H.263 Version 2 (H.263+ ) and its three negotiable modes are discussed in details. The experimental results show that H.263+ can improve the compression performance. The tradeoff between compression performances, complexity and memory requirements are also discussed.
