T-VIPS, a global specialist in professional video contribution and distribution solutions, has announced 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 resynchronisation, a process that typically takes time to complete. This resynchronisation must be done on all modulators in a particular SFN region, therefore any issues can affect a large number of customers.
