摘　　要：在Davinci ARM+DSP双核平台上开发基于3G网络的移动视频监控系统收发终端。将编解码运算分离出来与上层应用控制程序并行运行,提高系统工作效率。在平台上构建3G联网环境,实现并优化针对3G有线/无线混合网络的传输策略。仿真结果显示监控系统能够满足异构网络环境中监控信息被多方共享的需求,适应模拟3G混合网络中复杂丢包情况,最大程度减小视频流传输质量损害。Develop mobile video surveillance system terminal based on 3G network using Davinci Arm＋DSP dual-core platform.Divide the codec function from upper-layer application,and make them run in parallel to promote the system efficiency.Build connection between platform and 3G network,optimize the software complement of transmission strategy to 3G hybrid network.The result of the simulation shows that the surveillance system can provide information shared by supervisors in heterogeneous network,adapt to the complicated package loss situation in simulative 3G network,and minimize the damage to the quality of video streaming.
