Thomson focusses on energy efficiency11 August 2012
Thomson Broadcast is showcasing its complete range of energy efficient, reliable solutions for the deployment of environmentally friendly, cost-effective terrestrial transmission networks at IBC.
The Futhura GreenPower TV Transmitter family of high-power digital reference transmitters is now equipped with an increased operating range from 1.6kW to 11.6kW – UHF wideband. The cooling system has been completely redesigned to provide further energy savings and the ability to adapt to any environmental conditions. Further, the Vithal VHF GreenPower TV Transmitters are now ready for DAB.
Also showcasing at IBC2012 will be the company’s drain modulation technology –an amplification technology that Thomson Broadcast said could save a lot of energy while also improving the total reliability of the transmission system. It added that this would address broadcasters’ major day-to-day efforts to reduce the total cost of ownership of their system.
Also in Amsterdam, Thomson Broadcast will stage workshops and live demonstrations based on its latest research on DVB-T2 lite transmissions, including extreme PLP processing, energy efficiency improvement, PAPR, measurement and analysis techniques on DVB-T2 signal, and optimised DVB-T2 network management.
Finally, Thomson Broadcast’s newly developed Adaptive Precorrection System will be shown at IBC2012 for the first time. The system is designed to improve the output spectrum as well as the MER (Modulation Error Rate) of shortwave DRM transmitters promising the best signal on air. This enhanced signal quality results in more efficient coverage and energy usage along the transmission chain, and gives excellent audio performance in AM mode. – Anne Morris
