Large scale test of the ATSC3.0 system in Oregon benefits from TeamCast technology


TeamCast, the world-renowned leader in digital modulation technologies for Digital Terrestrial Television (DTT), Wireless Transmission and Satellite Applications, announce they have provided VORTEX II ATSC 3.0 exciters to WatchTV, Portland (Oregon).

Broadcaster WatchTV has been granted an experimental license by the FCC to begin broadcasting in ATSC 3.0 on 4 of their 5 Class A stations in the Portland market. They have also been granted permission to build and operate 8 “Gap Fillers” from two different locations.

Their intent is to conduct tests of ATSC 3.0 format, multi-frequency network testing including channel bonding, as well as SFN testing on all four channels with the above mentioned gap filler sites.

WatchTV wants to learn more about the propagation characteristics of ATSC 3.0 in a geographic area where the terrain is more mountainous than in the prior experiments; to explore the capacity of the ATSC 3.0 platform to deliver multiple data services along with television programming in multiple formats; to determine the benefits of a multifrequency network for multiplying the data capacity of ATSC 3.0; and to explore the robustness and capabilities of a multifrequency system to deliver video and other content to mobile receivers.

“We are excited to contribute to this new field experiment of the ATSC 3.0 system, after the tests performed by Sinclair Broadcast Group / ONE Media in the Washington / Baltimore area” says Eric Pinson, head of Business Unit at TeamCast. “COFDM and SFN are technologies we have been working with for more than 20 years, and ATSC 3.0 is promising to take the best of them”, he adds.

The VORTEX exciters used in the Portland test are shown at IBC 2017 on TeamCast’s stand #2.B51.
