IPGuard - Seamless IP switch


1+1 redundancy of IP streams with bypass


seamless IP switch with LAN bypass


Nowadays, IP network is commonly used to carry any kind of data services. Broadcast network operators are migrating to the IP infrastructure to deliver audiovisual content. Head-end equipments manage also the distribution of audiovisual services using the IP protocol technology. IPGuard is the solution to provide automatic 1+1 redundancy of network equipments that outputs IP streams such as multiplexers, DVB-T2 gateways,...


The IPGuard offers a bypass mechanism in order to offer 100% of service availability in case of power outage or unit failure. Combined with ENENSYS DVB-T2 Gateway and the patented technology T2Guard, IPGuard offers a unique and secure solution to provide a seamless switch-over between both DVB-T2 gateways that deliver T2-MI streams over IP network.

T2Gateway redundancy over IP

The IPGuard can also be operated to re-synchronize and re-align the same MPEG-2 TS that is carried over redundant IP-based networks. The latter introducing different network propagation delay, the IPGuard is able to re-align both IP streams to provide a seamless change-over between the incoming IP streams.
