IP组播在IP网络中实现了多点通信模型,促进了视频点播、音视频会议和数据分发等多点通信业务在互联网上的发展,是互联网络发展的一个重要方向。采用IP组播技术实现监控视频的多点传输,可以大大节省网络带宽资源,提高数据传送的效率。本文对IP组播技术和其在视频监控系统中的应用作了介绍。给出了组播技术在视频传输系统中的设计思想与实现方法。运行结果表明,方案合理,运行可靠。
IP multicast in the IP network to achieve a multipoint communication model, and promote the video on demand, audio and video conferencing and data distribution and other multipoint communication services on the Internet development is an important direction for the development of the Internet. The use of IP multicast technology to monitor multi-point video transmission, can greatly save network bandwidth resources and improve data transmission efficiency. This paper introduces IP multicast technology and its application in video surveillance system. The design idea and implementation method of multicast technology in video transmission system are given. Operation results show that the program is reasonable and reliable operation.
