Harmonic Advanced Media Processor adds functionality to reduce broadcast distribution costs and expand support for evolving TV standards, including ATSC 3.0 in the US and DTV+ in Brazil.
Harmonic’s recent update to its XOS Advanced Media Processor adds capabilities that aim to reduce the cost of broadcast distribution and expand support for evolving television standards, including ATSC 3.0 in the United States and DTV+ in Brazil.
The XOS media processor combines playout, encoding and broadcast delivery workflows into a single appliance. This new version extends that functionality across three main areas – improving the ATSC 3.0 viewer experience, lowering the cost of DTV+ deployment and supporting the industry's gradual shift from satellite to IP-based distribution.
ATSC 3.0 and DTV+
On the ATSC 3.0 side, the updated processor adds support for Dolby Vision advanced HDR with look management, gives broadcasters scope to optimise HDR content across different display types. It also incorporates Dolby Atmos object-based audio, including audio description and dialogue enhancement, which broadens accessibility for viewers. Both features are integrated into the existing software-based playout-to-delivery workflow.
For DTV+ deployments, Harmonic says the XOS processor opens an opportunity to reduce infrastructure costs by combining playout, encoding and gateway functionality within the one device. The processor supports up to date codecs including VVC, LCEVC and MPEG-H audio, and integrates ROUTE and STLTP (Studio to Transmitter Link Tunneling Protocol defined by ATSC group) gateway functionality for centralised management of DTV+ parameters.
C-Band Satellite to Ku-Band
The update also addresses the ongoing migration from C-Band satellite to Ku-Band and IP distribution. The processor supports both traditional satellite workflows and IP-based distribution using SRT or RIST alongside CDN delivery. It also incorporates satellite Ku-Band downlink and RIST packet recovery over IP, giving broadcasters a path away from legacy satellite infrastructure without disrupting primary distribution.
Stéphane Cloirec, Vice President of Video Appliances and Software Product Management at Harmonic, said broadcasters worldwide are navigating significant change, from spectrum reallocations to the rollout of new television standards. "The enhanced XOS Advanced Media Processor eases these transitions, helping broadcasters modernise operations and reduce infrastructure complexity," he said.
Harmonic will demonstrate the updated XOS processor at NAB 2026, taking place 19–22 April in Las Vegas. http://www.harmonicinc.com/.
