SAN JOSE, Calif. — March 18, 2026 — Harmonic (NASDAQ: HLIT) today announced significant enhancements to its XOS Advanced Media Processor that lower the cost of broadcast distribution while enabling outstanding viewing experiences. The expanded capabilities to the award-winning media processor advance key broadcast industry evolutions, including the migration from C-Band satellite to Ku-Band and IP distribution, the continued rollout of ATSC 3.0 in the United States and the adoption of DTV+ in Brazil.

“Broadcasters around the world are navigating major transformations, from spectrum reallocations to migrations to next-generation television standards like ATSC 3.0 and DTV+,” said Stéphane Cloirec, vice president, video appliances and software product management, video business at Harmonic. “With newly enhanced capabilities, our XOS Advanced Media Processor eases these transitions, helping broadcasters modernize operations, deliver richer viewing experiences and reduce infrastructure complexity.”

Harmonic’s XOS Advanced Media Processor now supports Dolby Vision® advanced HDR with look management, enabling broadcasters to optimize HDR content across display types and preserve creative intent on any screen. The XOS media processor also includes Dolby Atmos® object-based audio with support for audio description and dialog enhancement, improving accessibility and enabling more immersive viewer experiences. These innovations enable broadcasters to deliver richer NextGen TV applications while leveraging the same software-based playout-to-delivery workflow.

The XOS media processor lowers the cost of DTV+ deployments by integrating playout, encoding and gateway functionality into a single appliance. It supports codecs including VVC, LCEVC and MPEG-H audio, along with ROUTE and STLTP gateway functionality for centralized management of DTV+ parameters. For IP delivery, the XOS media processor supports both traditional satellite workflows and IP-based distribution using SRT or RIST, together with CDN distribution, and offers hybrid satellite and IP delivery including satellite Ku-Band downlink and RIST packet recovery over IP.

Harmonic will demonstrate the latest innovations to the XOS Advanced Media Processor at the 2026 NAB Show, April 19–22, in Las Vegas in booth W2831. Further information about Harmonic and the company’s solutions is available at www.harmonicinc.com.
