T-VIPS DVB-T2 gateways and seamless SFN switching solution deployed for robust distribution of Freeview HD

August 8, 2011

T-VIPS, a global specialist in professional video contribution and distribution solutions, hasannounced that the T-VIPS TNS541 Seamless TS Monitoring Switch and the CP560 DVB-T2 Gateway have been installed to provide seamless switching within the Arqiva DVB-T2/SFN digital terrestrial network. The phased roll-out began in April 2011 and is scheduled to be completed in time for the London 2012 Olympics.

In order to preserve SFN operation and avoid DVB-T2 modulators losing synchronization, the solution involves the use of two independent CP560 DVB-T2 Gateways and a TNS541 Seamless TS Monitoring Switch. This prevents service outages caused by DVB-T2 modulator resynchronization, a process that typically takes time to complete. This resynchronization must be done on all modulators in a particular SFN region, therefore any issues can affect a large number of customers.

“I am delighted that we have been able to help Arqiva enhance the robustness and reliability of the delivery of Freeview HD in the UK,” said Johnny Dolvik, CEO, T-VIPS. “Given the importance of this type of service, it’s crucial that every technology deployment runs as smoothly as possible. I’m pleased to say that T-VIPS has been involved with Arqiva right from the start and it’s great news that our intelligent seamlessly switched 1+1 redundancy solution is now enhancing Arqiva’s managed Freeview HD network.”
