中文说明： 高效视频编码(HEVC)采用了多种先进的编码工具来大幅度提高压缩效率，但同时也带来了高的编码复杂度。考虑到LCU编码时需遍历所有的CU模式、PU模式和7ITU模式．来确定当前LCU的最优模式组合．其过程 耗时较大。针对这点本文分别对CU、PU和，ITU提出模式判决过程优化算法．同时，每一种PU模式在进行运动矢量搜索时复杂度较高，继而提出运动估计优化方法。实验结果表明，相比于原始的HEVC编码方法，高速模式判决 算法可将编码速度提高近15～20倍。
English Description：
High efficiency video coding (HEVC) use a variety of advanced coding tools to substantially improve compression efficiency, but it also brings a higher encoding complex Miscellaneous. When considering the LCU coding need to loop through all the CU, PU mode and 7ITU mode. To determine the optimal model of composite current LCU. Time consuming larger. On this point this article separately for CU, PU, ITU proposed mode decision optimization algorithm. At the same time, each PU mode motion vector Search complexity is high, then make optimization method for motion estimation. Experimental results show that, compared with the original HEVC encoding method, high speed mode decision Nearly 15~20 times faster algorithm can be coded.
