摘　　要：视频监控系统建设过程中,经常需要融合多种不同标准视频资源。针对这一需求,总结出不同标准视频资源的3种差异,采用COM组件技术封装这些差异,对不同的视频资源,只需要更新相应COM组件,不需要重新编译上层应用。另外,采用自主研发的成熟流媒体服务技术,能有效节省视频码流传输带宽并保证实时性。构建仿真试验环境,验证系统架构的有效性,试验结果标明,系统能快速融合新视频资源。In the process of video surveillance system construction, various video resources need to be integrated. Aiming at this requirement,three kinds of differences between different video resourcesare discussed.By encapsulating these differences in COM com- ponents,the different video resources can be integrated only by updating COM components,the upper application need not be compiled again.Besides, a mature and independent streaming media technology is used for bandwidth saving and real-time characteristics.Finally, a simulation environment is constructed to verify the availability of architecture.The experiment results show that the system can rapidly fuse new video resources.
