【摘要】：近些年以来，随着时代的发展和科学的进步，我们已经进入了数字化、信息化的时代。数字化和信息化主要的内容包括对视频图像和音频数据的数字化处理。由此，无论是在工业生产环节还是在日常生产和生活中，对视频监控的需求与日俱增。建立在计算机网络和多媒体技术上的视频监控系统有着十分广阔的应用前景。本文主要研究的是基于arm体系架构下的嵌入式视频服务器的开发和研究。相对于第一代模拟视频监控系统，基于arm体系家构下的视频服务器是数字化的系统，其特点是便于网络传输和扩展能力强。而相对于基于PC或者服务器平台的视频服务器为核心的第二代数字化监控系统来说，，基于嵌入式的视频服务器为核心的监控系统有着高实时性、高稳定性、抗病毒和性价比高等特点。在本文的研究中，我们选用基于ARM9体系架构的S3C2440芯片为核心的JZ2440开发板作为视频服务器开发的硬件基础，配合linux-2.6.22.6为内核的操作系统作为嵌入式服务器系统开发平台，基于B/S（Browser/Server）的服务机制，使得客户端直接通过浏览器就可以进行视频监控。嵌入式网络视频服务器，实现了视频流的网络传输，测试显示系统具有较好的实用性和稳定性。
[Abstract]:In recent years, with the development of the times and scientific progress, we have entered the digital, information age. The main contents of digitization and informatization include digital processing of video image and audio data. Therefore, both in industrial production and in daily production and daily life, the demand for video surveillance is increasing. The video surveillance system based on computer network and multimedia technology has a very broad application prospect. This paper mainly studies the development and research of embedded video server based on arm architecture. Compared with the first generation analog video surveillance system, the video server based on arm architecture is a digital system, which is characterized by its strong ability of network transmission and expansion. Compared with the second generation digital monitoring system based on PC or server platform, the embedded video server based monitoring system has high real-time and high stability. Anti-virus and high cost-performance features. In the research of this paper, we choose the S3C2440 chip based on ARM9 architecture as the core JZ2440 development board as the hardware base of the video server development, and the operating system based on linux-2.6.22.6 as the embedded server system development platform. The service mechanism based on B / S browser / Server enables the client to monitor video directly through the browser. The embedded network video server realizes the network transmission of video stream, and the test display system has good practicability and stability.
