【摘要】 详细地分析了两大标准化组织最新提出的视频编码国际标准H.264中的整数变换及量化过程。H.264视频编码的基本框架类似于当前流行的视频编码标准,采用变换编码和预测编码的混合编码技术,其优异的性能来源于引入的4×4整数变换,是所有视频压缩编码标准协议中独一无二的。最后在32位超高性能的多媒体处理器TMZJ2004上进行实验,对DCT、整数变换、DCT余弦值定点三种变换编码进行了信噪比(PSNR)比较。更多还原

【Abstract】 Analysing two big organizations for standardizations suggested the integer transform and quantification course which in the newest video coding international standard H.264.The basic video coding frame of H.264 is more similar than now popular video coding standard,with transform coding and prediction coding mix coding technology.Its excellent performa￣nce sources in the integer transform of 4×4,it is only one in all video compressed coding standard protocol.In the end,the experiments on 32 exceeds multi-media processor TMZJ2004 of high performance are carried out,and DCT and integer with DCT cosine value transform coding are compared on signal-to-noise ratio(PSNR).更多还原
