| 摘 要： | 视频编码新标准H．264／AVC与先前的标准如MPEG2、H．263、MPEG4第2部分相比，虽具有更高的编码效率和差错鲁棒性，但是这些编码效率的提高是以增加编码器和解码器的复杂度为代价的。研究表明，由于H．264／AVC编解码器的计算复杂度比其他视频压缩标准高出几倍甚至十几倍，因此实现实时编解码器需要寻找高效的优化方法。为了对解码器进行优化，从软件和硬件平台的角度提出了一种解码器的优化方法，最后进行了实验，实验结果显示，优化后的软件解码器能够达到实时解码。

| Abstract: | The new international video coding standard H. 264/AVC has significant improvements in coding efficiency and error robustness in comparison with the previous standards such as MPEG2, H. 263, MPEG4 part 2. But improved coding efficiency comes at the expense of adding complexity to coder/decoder. The research shows the conclusion that the calculation complexity of H. 264/AVC codec has several times as the previous standards, so as to get real time codec we must find high-effective optimization methods. The paper introduces the optimization solutions on software and hardware. The experimental outcomes are shown to achieve real time decoding with the optimized decoder. |
