[SatBroadcasting™] Arqiva, a communications infrastructure and media services company, has selected Thomson Broadcast (formerly the transmission division of Grass Valley) for the high-power sites of its new DVB-T2 network for terrestrial HD services in the United Kingdom. Thomson Broadcast is deploying, from 2010 to 2012, 16 high-power DCX Paragon MSDC-IOT transmitters with an output power up to 20 kW. The first on-air installation is set for later this year. As a long-time supplier to Arqiva, Thomson Broadcast is also upgrading the four already installed DVB-T DCX Paragon transmitters with new high-performance DVB-T2 Sirius exciters. The new generation of solid-state Elite GreenPower transmitters is also equipped with the Sirius open-platform exciter, which features real-time Digital Adaptive Pre-correction (DAP) for excellent stability and signal quality — regardless of variations in typical environmental conditions.
