| 摘 要： | 为了方便H.264/AVC在低码率高时性应用系统中的实现,须对其编码算法进行优化.本文首先对H.264/AVC编码器进行了深入的分析,然后在此基础上提出了块模式选择的并行设计方案,并对此方案进行了并行设计与实现.最后对此设计方案在多核服务器上进行了试验.试验结果表明:并行后的三步搜索算法在不影响H.264编码质量的前提下,其编码速度平均提高了2.73倍以上.

| Abstract: | To facilitate H.264/AVC implement in the application system with high low rate,its coding algorithm needs to be optimized.This paper first analyzes the H.264/AVC encoder deeply,then on the basis of it presents the parallel design program of block mode selection and parallel designs and implements this program.Finally the design program is tested on multi-core server and the testing results show that the encoding speed of the three-step search algorithm after parallel improves by an average of 2.73 times wit... |
