摘要
介绍和分析了H .2 6 4采用的新编码技术 ,诸如 1 /4和 1 /8像素精度运动估计 ,可变大小的图像分块 ,多参考帧 ,新的熵编码算法等 .新编码技术的采用使H .2 6 4的编码性能得到大幅提升 ;通过与H .2 6 3编码模型的实验性能对比测试 ,比较分析了H .2 6
The new features of H.264 coding technology were introduced and analyzed such as 1/4 and 1/8 pixels precision, different block size for motion estimation, multiple reference frames, new entropy coding Algorithm etc. The use of new coding technologies makes H.264 more significantly enhanced in performance. Through comparison of the performance of H.263 with that of H.264 by experiment, the advantages and disadvantages of H.264 coding technology were declared.
