Abstract: The dual network port redundancy system is a communication control system under the computer network technology. This paper mainly develops a video coding and decoding system with dual network ports based on 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, has the rapid recovery capability and improves the overall system Stability, reliability, safety and real-time. Redundant backup of the network port, when the normal communication network or line failure 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.
