摘　　要：在嵌入式Linux环境下设计实现一个由SIP信令控制的视频监控客户端。该系统以OMAP3530芯片为硬件平台核心,采用H.264作为视频编码标准,并将会话初始协议用于整个系统的信令控制。系统功能包括SIP注册与退出、SIP呼叫与挂断、音视频数据流控制、播放和存储等功能。该设计充分利用了H.264算法标准在数据压缩率和网络友好性等方面的优势,并利用了OMAP3530双核架构的特性,由ARM核完成系统的管理和控制,DSP进行解码。实验结果证明,该方法建立的监控客户端具有高性能、低功耗、实时性强、运行稳定的特点。In the embedded Linux environment, it outlines the design and implementation of video monitoring client software which is controlled by the SIP signaling. It uses the OMAP3530 chip as the core hardware platform, uses H.264 as the video coding standard, and the session initiation protocol is used to control the whole system. System features include SIP registration and exit, SIP call and hang up, audio and video data flow control, play and storage functions. The design makes full use of the H.264 standard in data compression algorithm, network-friendly and other areas, and uses the OMAP3530 dual-core architecture features, ARM core complete system management and control, and DSP decoding. Experimental results show that the establishments of a monitoring client through this method have high-performance, low power, and strong real-time, stable operation characteristics.
