摘　　要：从软件工程层面分析了嵌入式SoC达芬奇平台的硬件系统、架构和组件技术,介绍了达芬奇软件资源、操作系统移植、流媒体应用系统搭建以及嵌入式中间件的概念,提出了利用达芬奇架构和H.264算法组件设计一个高质量、低成本的基于SIP的流媒体传输系统的方法,详细阐述了现场端嵌入式系统的硬件设计和监控中心软件的实现.嵌入式视频服务器在网络和远程视频监控中得到了较好的应用,与传统的视频监控系统相比较,该方案具有成本低、体积小、稳定性好、可靠度高等优点.Firstly the hardwares, architecture and component technology of the embedded SoC DaVinci platform are analysed in the software engineering aspects. Then the developing resources of the system, operating system transplantation, establishment of streaming media system and the concept of the embedded middleware are introduced. A high quality, low-cost scheme of SIP-based streaming media transform systems delivery by H. 264 coded algorithm and DaVinei platform are also proposed. The Embedded Video Server is now widely used in video conferencing and remote monitoring field. Compared with the traditional video surveillance system,the system has the advantages of low cost, small size, stability and high reliability.
