摘要： 设计并实现了一个基于IPMulticast技术的远程数字音视频监控系统,提出了分布式音视频接入和共享的传输方案,能够有效地节省网络带宽。该系统另一个特点是考虑到有的网络路由器不支持组播或者没有打开组播功能等因素,设计了“自适应切换单播通道和组播通道”的解决方案;并针对视频、音频语音和控制数据的不同传输特点,对其所采用的传输技术作了探讨,给出了工作模块的实现方法。

Abstract: This paper designs and implements a remote digital audio/video surveillance system based on IP multicast.The solution of distributed accessing and sharing of audio-video is presented,which could effectively save the bandwidth of the network.meanwhile,this system has another characteristic,of automatically switching multicast channel and unicast one for that some routers doesn’t support or switch on IP multicast.Considering that the different transmission features of audio/video data and control data,it discusses the transmission technology adapted and gives the specific implement method of main modules.
