The IPGuard™ offers a bypass mechanism in order to offer 100% of service availability in case of power outage or unit failure. It is designed to provide an automatic 1+1 redundancy of network equipment that delivers services over IP such as encoders, multiplexers, DVB-T2 gateways, ASI to IP adapters,… Additionally, the IPGuard™ can also be operated to re-synchronize and re-align the same MPEG-2 TS or T2-MI stream 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 redundant IP streams.
“We are really proud to offer to the digital TV market the world’s first and unique solution that can guarantee a reliable delivery of any digital TV, radio and data services over IP networks”, said Laurent Roul, ENENSYS networks product manager. “Most of our customers were looking for a solution that could really provide a 1+1 automatic redundancy at the IP level as the well-known ASI matrixes do so far. The IPGuard™ embeds the same technology as the ENENSYS’ ASIGuard™ seamless ASI switch to provide a wide range of change-over possibilities from regular MPEG-2 Transport Streams to SFN feeds up to the new T2-MI streams. With IPGuard™, operators can definitely migrate to an IP only network delivery in confidence”.
