【摘要】 针对当前主流的监控系统受网络带宽的限制等问题,提出了在有较好扩展性的实时流协议基础上实现的网络监控系统。分析讨论了实时流协议的协议格式、特点和参数,并介绍了H.264编解码技术,基于开源项目Live555实现了多媒体服务端,具备网络监控系统的实时播放和回放模式。与基于HTTP协议的网络监控系统进行性能比较,在针对帧率和花屏等方面有了大幅度提高。更多还原

【Abstract】 Web DVR system based on a better scalability real-time streaming protocol in the market monitoring system is proposed which constrant by network bandwidth.First,the real-time streaming protocols’ format,characteristics and parameters are discussed,and the H.264 codec technology is described.Then,the open source project of Live555 is used to develop media services and implement the web DVR system,which contain real-time mode and playback mode.Finally,comparison with the performance of web DVR based on HTTP protocol,the results show that methodologist and strategies are feasible.更多还原
