本文的工作是实现一个视频监控系统的软件核心部分。在内容上首先对
H. 263视频编码标准进行叙述，接下来讨论实现快速运动估计的方法，针对块
匹配运动估计给出了一种改进的钻石搜索算法代替原有的三步搜索法。实验
结果证明，经算法改进优化的新钻石搜索法优于原先的三步攫索法，大大提
高了程序运行的效率。随后简单介绍了C64xx系列DSP和视频数据的AVI存
储方式，研究了用软件的方法实现 H. 263编码标准，以及将其移植到 DSP后
的优化问题，最终达到了在 DSP上实时编码的要求。-This article is the realization of a video surveillance system in the core of the software. First of all, the contents of H. 263 video coding standards are described, followed by discussion of fast motion estimation methods, for block-matching motion estimation is given an improved search algorithm in place of the original diamond three-step search method. Experimental results show that by the algorithm to improve the optimization of the new diamond search method is superior to the original three captured Sofa, greatly improve the efficiency of the program is running. Then briefly introduce the DSP Series C64xx and AVI video data storage, research using the software method H. 263 coding standard, and its transplantation to the DSP after the optimization problems, and ultimately reached in the DSP real-time encoding requirements.
