Harmonic (NASDAQ: HLIT) announced enhancements to its XOS Advanced Media Processor designed to reduce broadcast distribution costs and support industry transitions including C-Band to Ku-Band satellite migration, ATSC 3.0 rollout in the United States, and DTV+ adoption in Brazil.

The updated media processor combines playout, encoding and broadcast delivery functions in a single solution. New capabilities include support for Dolby Vision HDR with look management and Dolby Atmos object-based audio for ATSC 3.0 deployments, allowing broadcasters to optimize content across display types and enhance accessibility features.

For DTV+ deployments, the processor integrates playout, encoding and gateway functionality into one appliance. It supports advanced codecs including VVC, LCEVC and MPEG-H audio, and includes ROUTE and STLTP gateway functionality for centralized parameter management.

The system supports both traditional satellite workflows and IP-based distribution using SRT or RIST protocols with CDN distribution. It offers hybrid satellite and IP delivery capabilities, incorporating satellite Ku-Band downlink and RIST packet recovery over IP to help broadcasters transition from legacy satellite infrastructure.

"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 of video appliances and software product management at Harmonic's video business.

Harmonic will demonstrate the enhanced XOS Advanced Media Processor at the 2026 NAB Show from April 19-22 in Las Vegas at booth W2831.
