ENENSYS Releases New ASI Switcher

News Image
ENENSYS has released its new ASI switcher technology, ASIIPGuard, an upgrade of its ASI switches.

ASIIPGuard provides automatic switching capabilities between two ASI sources and can also be used as a 1+1 redundancy solution.
Laurent Roul, Broadcast Networks Product Line Manager, said: "The launch of ASIIPGuard is the latest development from us designed to provide network efficiency and a premium quality viewer experience.
"It allows broadcasters to avoid transmitter de-synchronisation and transmission blackouts in DTT SFN (single frequency network) environments, which is vital. The technology is equally important in other broadcast networks too."
When operating at transmission sites, ASIIPGuard analyses and realigns transport feed data to seamlessly switch over inputs, selecting the most apt DVB-S/S2 source from either ASI, IP or satellite inputs.
The solution is primarily designed for cases where there is a main and backup feed, such as when the Multiple Program Transport Stream (MPTS) is delivered over IP with a satellite stream as backup. If errors are detected within the IP stream (at IP or MPTS level), the system will automatically switch to the satellite input to select a better quality source for onward transmission.
ASIIPGuard is fully compatible with the new ENENSYS HDc chassis, providing high-density switching. The HDc chassis allows modules and power sources to be hot swappable. The HDc platform is highly scalable and can run up to six ASIIPGuard modules to enable six ASI switch functions in 1U.
The ASIIPGuard has been designed as a 2:1 automatic ASI switch to provide redundancy for any equipment with ASI connections. With up to three ASI, two IP and one satellite input, it offers the option to switch between three feeds to become a 3:1 automatic ASI switch.
