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.
