摘要
为了满足各行业对远程监控的需求,提出基于IP网络的远程数字监控系统,系统采用H.264编码,提高了视频编码的效果和压缩比,降低视频流,即可达到理想的是实时性。同时利用现有的TCP/IP网络中的RTP/RTCP的传输协议实行实时性保证,采用IP组播满足视频监控网络通信带宽的不足的瓶颈。解决了传统模拟系统数据量大,远程传输效率低,实时性差的问题。其中本文重点介绍了IP组播通信和实时性保证的技术。
In order to meet the needs of remote monitoring of various industries, IP network-based remote digital monitoring system is introduced, sysyem uses H.264 encoding, improve the effectiveness of the video encoding and compression ratio, reducing the video stream, you can achieve the desired real-time are. At the same time using the existing TCP / IP network RTP / RTCP transport protocol to ensure the implementation of real-time, using multicast IP video surveillance network to meet the shortage of communications bandwidth bottleneck. Solve the traditional analog system data volume is very large, long-distance transmission is inefficient and bad real-time problems. This article focuses on one of IP multicast communications and real-time to ensure that technology.
