This will be the company's first transmitter range with IP capability

Over air delivery technology provider GatesAir is launching its first transmitter range with native IP capability at IBC2016.

The Maxiva UAXTE is a new range of air-cooled UHF transmitters for over-the-air DTV standards (ATSC, DVB-T/T2, ISDB-Tb), which aims to benefit from the flexibility of IP networking and connectivity. Its software-defined modulation allows migration to future digital TV standards worldwide, including the emerging ATSC 3.0 modulation.

To enable native IP capability, the Maxiva UAXTE incorporates GatesAir’s modulator from the recently-released Maxiva XTE exciter which obviates the need to retrofit previous-generation Maxiva air-cooled transmitters with additional gear.

The architecture of the UAXTE, based on the GatesAir PowerSmart Plus architecture with broadband amplification for lower operational costs, aims to reduce energy use and fewer internal parts. The XTE modulator integration also delivers an increase in digital signal processing capability, using the CPU processing technology based on Advanced RISC Machines (ARM); and up to date FGPAs. The improved processing power correlates directly to enhanced real-time adaptive correction capabilities in the XTE modulator’s proprietary GatesAir RTAC software which supports improved over-the-air reception for DTV consumers.

The UAXTE design also has an integrated, unified control system which centralises control functionality into a single user interface, allowing engineers to control all settings and parameters. 

“Since unveiling our high-performance Maxiva XTE exciter at IBC2015, our engineering team has been working toward a solution that would directly incorporate the benefits of IP networking and significantly improved processing power directly into our high-efficiency air-cooled transmitters,” said Rich Redmond, chief product officer, GatesAir. “The UAXTE design achieves this while introducing next-gen signal correction and new control and monitoring efficiencies that further enhance reliability and performance for DTV broadcasters worldwide.”
