摘要
双网口冗余系统是计算机网络技术下的通信控制系统,主要是根据视频安防监控系统的需求研制出的一个双网口冗余的视频编解码系统.整个系统主要包括冗余网络模块、视频编码模块、视频解码模块以及相应的IO传输模块.其中冗余网络模块是该视频编解码系统的核心模块,通过冗余网络可以快速及时地进行监控视频的编解码传输,并且能够实时地响应网络传输故障,具有快速恢复能力,提高了整个系统的稳定性、可靠性、安全性和实时性.对网口进行双冗余备份,当正常通信的网口或者线路出现故障时能自动地切换到备份的网口上.详细描述了一种双网口冗余的视频编解码系统的设计与实现.
The dual network port redundancy system is a communication control system whichbased on the computer network technology. This paper mainly develops a video coding anddecoding system with dual network ports according to the requirements of the video security monitoring system. The whole system mainly includes redundant network module, video coding module, video decoding module and corresponding IO transmission module. The redundant network module is the core module of the video codec system. Through the redundant network, the surveillance video can be encoded and transmitted quickly and timely. The redundant network module can respond to the network transmission failure in real time, it has the rapid recoverycapabiliAy and improves Ahe overal sysAem SAabiliAy, reliabiliAy, safeAy and insAanAaneiAy.Redundant backup of the network port, when the normal communication network can automatically switch to the backup network port. This paper describes in detail the design and implementation of a dual network port redundant video encoding and decoding system.
