Enhancements to Harmonic's Sports Streaming Solution Introduce Server-Side Multiview, Contextual Metadata-Driven Advertising, Dynamic In-Stream Ads and Robust Content Protection

SAN JOSE, Calif., March 26, 2026 /PRNewswire/ -- Harmonic (NASDAQ: HLIT) today announced powerful new innovations that further elevate the company's sports streaming solution. The advanced capabilities enhance fan engagement, unlock new opportunities for sports content monetization and strengthen content protection. Harmonic's advanced sports streaming platform empowers sports broadcasters, pure streamers, service providers and rights holders to meet the rising demand for immersive, interactive streaming experiences while maximizing the value and security of premium live sports content.

"Live sports represent the most valuable and demanding content in streaming today," said Jean Macher, senior director of global SaaS solutions at Harmonic. "Sports fans expect immersive, real-time experiences — and sports rights buyers need solutions that can monetize live events while delivering compelling viewing experiences that keep fans engaged. Our enhanced live sports streaming solution, built through collaboration across the sports ecosystem, reinforces Harmonic's commitment to helping customers maintain a competitive edge in an increasingly dynamic marketplace."

Enhance Fan Engagement with Multiview
Harmonic's new in-house server-side multiview solution allows fans to watch multiple games or camera angles simultaneously. The new capability is compatible with any end devices, ensures synchronized playback with exceptional video quality and low latency, and can be deployed in a geo-redundant environment for maximum reliability. Through API or UI, customers can easily compose any HD or UHD multiview templates.

Unlock Programmatic Advertising Through Scene-level Contextual Targeting
Harmonic's live sports streaming solution now supports programmatic advertising for live sports CTV inventory in collaboration with Viant Technology and its contextual intelligence platform IRIS.TV. The solution automatically generates scene-level contextual segments, including game start and end times, score changes, and key moments, and activates it within Viant's AI-powered demand-side platform, purpose-built for CTV.

This enables advertisers to bid on highly relevant sports inventory with greater precision and measurable performance outcomes. This innovation also allows publishers to monetize premium moments in real time, including unpredictable events such as overtime, maximizing the value of live sports inventory while delivering more contextually aligned advertising experiences.

Boost Monetization with Dynamic In-Stream Advertising
Server-side in-stream advertising capabilities on Harmonic's live sports streaming solution are now in production by a leading U.S. regional sports network. Harmonic's solution dynamically triggers ads based on real-time game moments. Already deployed during live NBA and NHL games, this capability allows sports rights holders to monetize high-action moments without interrupting the viewing experience. In-stream advertising can also be enabled on the new server-side multiview channels for further monetization. 

Protect Premium Sports Content with Scalable Watermarking
Harmonic strengthens content protection with integrated, service-based forensic watermarking, helping rights holders combat piracy at scale without added complexity. Through native integration with NAGRA NexGuard - part of NAGRAVISION's end-to-end streaming security solution - Harmonic enables watermarking as a service, delivering real-time traceability with minimal impact on latency or user experience. Harmonic has also integrated advanced solutions from Irdeto, including TraceMark™ watermarking with both A/B and distribution level watermarking. Together, these capabilities allow sports content owners to quickly identify and shut down illegal streams, protecting the value of premium live sports content.

Harmonic will demonstrate its enhanced live sports streaming solution at the 2026 NAB Show, April 19-22, in Las Vegas in booth W2831.
