Enabling IP broadcasting in confidence

Press release from: ENENSYS Technologies

At this year’s NAB, ENENSYS unveils the world’s first and unique seamless IP switch, IPGuard™, which provides safe delivery of any IP streams carrying digital TV, digital radio or data services to meet customers’ expectations with a reliable IP broadcasting.

With the emergence of IP networks, more and more the broadcast world is migrating from the famous ASI interface to the wide spread IP interface to offer more services and flexibilities. Although most of the broadcast equipment supports the delivery of services over IP networks, no solution allowed yet a secure delivery of those IP-based services. ENENSYS’ IPGuard™ is the perfect solution that guarantees a safe broadcasting of critical digital applications by allowing an automatic and seamless redundancy of IP services.

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”.
