摘要
视频监控系统对视频数据的实时性要求很高,并且在不同的网络状态下保证这一需求至关重要。文章应用RTP/RTCP协议、XMPP协议、H.264视频编码方法,设计了一种自适应性的视频监控系统。该系统能对网络状况及时做出响应,调整系统运行方式,保证视频图像的实时性。文章首先分析了视频监控系统的特性,指出了系统具有自适应性的必要性,然后阐述了系统的设计方法和技术实现,最后介绍了系统的实现和运行效果。
The video data transmitted in video surveillance system must have high requirement of real-time characteristics and work well on different network status, even if the network is congested. A video surveillance system with adaptability is developed by using the technology of RTP/RTCP, XMPP and H.264. By adjusting its behavior according to the quality of data distribution, such a system can provide delivery services for video data with best real-time characteristics. Firsdy, this paper indicates the adaptability of video surveillance system is very important according to its characteristics, then it illustrates the design method and technical implementation, and the system realization and function quality is described finally.
