GatesAir To Demo China's Digital Transition At BIRTV

News Image
GatesAir is to greet visitors to this year's BIRTV show with a demo of how over-the-air broadcasters serving viewers in China can transition to digital multichannel services while optimising existing analog TV and radio networks. The company will exhibit at Stand 8A03 in the CIEC, Beijing, China from August 27-30.

GatesAir’s complete Maxiva UHF transmitter range - including high-efficiency ULXT liquid-cooled and UAXT air-cooled models - cover all power requirements for China’s DTMB/CTTB (terrestrial) and CMMB (mobile) broadcast standards, while optimising analog TV broadcasts through to the digital transition.
Working in tandem with each standard’s bandwidth-efficient use of OFDM modulation for maximum throughput, Maxiva transmitters support DTMB/CTTB and CMMB multichannel services over the same network upon transition to digital.
GatesAir will also demonstrate its technical platform for China Digital Radio, a multi-standard system that supports hybrid digital and FM broadcast initiatives.
GatesAir’s experience in real-time adaptive correction of digital radio signals, achieved via its unique RTAC solution, integrates crest factor reduction techniques that outpace competitive solutions. This differentiator allows GatesAir to deliver higher peak output power with better efficiency in more compact transmitter designs.
The complete GatesAir China Digital Radio solution comprises Flexiva transmitters and specially tuned, software-defined Flexiva FAX exciters to process and amplify multichannel digital radio services. Program importing and exporting technologies similar to those used today in GatesAir’s HD Radio solution enable bandwidth-efficient, multichannel delivery to FAX exciters from studios and production locations via IP or legacy transport networks.
GatesAir’s PowerSmart 3D architecture is responsible for the long-term operational value of Maxiva and Flexiva transmitters, with high-efficiency designs that reduce transmitter footprints and rack space requirements by up to 75 percent; and enhance energy efficiencies to yield annual power savings exceeding 50 percent.
GatesAir’s complete over-the-air transport and deliver solutions for TV and radio also leverage on-air program delay technologies for content delivery across large single-frequency networks (SFNs).
"The transition from analog to digital broadcasting continues to take shape in China, with GatesAir today supporting both live deployments and beta tests for next-generation TV and radio services across the country," said Rich Redmond, chief product officer, GatesAir. "Our solutions for Chinese digital standards balance performance and quality with Total Cost of Ownership, with intelligent strategies to help broadcasters and network operators optimize existing analog networks throughout the digital transition process."
