Wireless, over-the-air content delivery solutions provider GatesAir is celebrating winning what it calls a ‘large’ digital TV (DTV) transmission contract with Chilean public service broadcaster Televisión Nacional de Chile (TVN Chile).

gatesair maxiva 2Oct2019Chile’s geography makes DTV transmission a unique challenge for broadcasters, with mountainous and coastal regions running north to south in close proximity through much of country. Content generated at TVN Chile’s Santiago headquarters is distributed to satellites in different regions, with unique programme multiplexes delivered in the north and the south.

The contract stipulates a three-year rollout of 124 ISDB-Tb DTV transmitters in key cities throughout Chile, with initial deployments focused on the metropolitan centres of Concepcion and Valparaiso City. The initial rollout includes a mix of Maxiva ULXTE liquid-cooled (1 kW and higher) and UAXTE air-cooled (under 1 kW) transmitters, with additional phases to follow.

TVN Chile is said to have selected GatesAir, one of 12 transmission suppliers under evaluation, due to its longevity, reliable customer service and support, and positive experiences with GatesAir analogue TV transmitters. TVN Chile also pointed to GatesAir’s high-efficiency transmitter designs and range of power levels as key factors in its decision.

“GatesAir has been in business for nearly 100 years, and has supported many of the largest national DTV transition projects worldwide,” explained TVN Chile chief engineer Mario Sepulveda. “Our experience with GatesAir has proven they can reliably support large transmission networks with technical resources and spare parts, quickly solve problems, and fortify projects with customer-friendly frame agreements and warranties. All of this speaks to the very high quality of their products and services. The very high efficiency of Maxiva transmitters will also reduce footprint and air conditioning at all of our transmission sites, lowering our total cost of ownership throughout Chile.”

GatesAir’s integrated remux technology will also see us to simplify regional content distribution. Maxiva transmitters in each region will receive their DTV broadcast multiplexes via satellite, and then remux the signals for transmission to regional viewers.
