T-VIPS , the video grant and placement businessman formed in Oslo, Norway, has voiced that its TNS541 Seamless TS Monitoring Switch and CP560 DVB-T2 Gateway have been commissioned to give seamless switching inside of the Arqiva DVB-T2/SFN digital terrestrial network. This network is used by UK free-to-air service Freeview together with by a couple of pay TV operators. The phased rollout began in April 2011 and is scheduled to be finished in time is to London 2012 Olympics when roughly the entire UK will be covered by Arqiva's second-generation DVB-T2 digital terrestrial network.
The network will encouragement SFN operation at least at a informal level, that reduces the amount of spectrum indispensable but requires synchronizing transmitters to prevent mortal interference between beside ones. To prevent the DVB-T2 modulators losing synchronization, the network involves the use of two eccentric CP560 DVB-T2 Gateways and a TNS541 Seamless TS Monitoring Switch. This prevents service outages caused by DVB-T2 modulator resynchronization, a routine that typically takes time to complete. This resynchronization contingency be done on all modulators in a specific SFN region, so any problems can start a considerable number of customers.
