GatesAir and Triveni Digital were selected as technology partners for an ATSC 3.0 deployment by Oklahoma Community Television (OCT), a division of Griffin Media.
The project focuses on creating a cost-efficient networking model for low-power transmission sites through combined RF and IP technologies. The successful proof-of-concept provides a basis for future ATSC 3.0 translator transitions.
Integration of SRT into RF Infrastructure
OCT General Manager Jack Mills developed a networking method that incorporates the SRT protocol directly into RF infrastructure using GatesAir transmitters and Triveni Digital signaling technologies. SRT supports secure, low-latency transport and is commonly used over managed fiber networks. For remote sites without fiber, extending physical connections is often too expensive.
Deployment at the Strong City Translator
One OCT translator faced this issue, leading Mills to test a new approach. OCT deployed two GatesAir Maxiva UAXTE-100 translators for ATSC 3.0 services. The first stage delivered NextGen TV broadcasts from five Oklahoma City network affiliates across 90 miles. The feed originated from KAUT-TV’s ATSC 3.0 Lighthouse and reached OCT’s Strong City site via SRT over existing fiber and IP paths. The signal passed through DTV Innovations equipment and was broadcast on Channel 29.
Solution for the Elk City Translator
The second translator site in Elk City lacked microwave, fiber, or wired connectivity. Mills chose an off-air RF hop from Strong City, requiring signal regeneration for a different RF channel. Triveni’s ATSC 3.0 Translator was selected to decode and regenerate the signal for Channel 26, lowering equipment costs. The device adds a DRM signature and feeds the regenerated signal to a GatesAir translator operating at 120 W.
Industry Context and Future Plans
Mills noted that the U.S. has about 5,000 low-power TV stations and translators. Any future ATSC 3.0 mandate will require affordable transition options to avoid service shutdowns. He stated that IP-based and over-the-air solutions can reliably support ATSC 3.0 delivery. He added that Triveni’s translator works with existing RF components without modification. OCT is evaluating additional ATSC 3.0-ready services, including Broadcast Positioning System (BPS) support.
