摘要 H.264是一种新提出来的视频压缩标准。本文首先介绍了 H.264中所采用的多宏块分割模式技术,然后对其中比较耗时的块分割模式选择模块进行测试分析,在此基础上提出了一种块分割模式选择算法,并对该算法进行了测试,实验结果表明:与JM8.2编码方案相比采用新的算法后的运行时间加速比可达到 4.5以上,峰值信噪比只是略有下降。 H. 264 is a newly proposed video compression standard. The multi-macroblock partition mode technology adopted in H. 264 is introduced first, then some tests and analysis on the block partition mode selection module which is time-consuming are carried out, and based on the analysis of the test results, a new block partition mode selection algorithm is proposed. Experimental results indicate that the new algorithm can achieve a speedup of above 4.5 compared with JMS. 2 and brings only a little degradation of PSNR.
