SVG Sit-Down: Harmonic's Jean Macher on Turning Live Sports Content Into a Smarter Monetization Engine

Dynamic ad insertion, AI-based technologies, programmatic advertising are some of the tools that are helping live sports streaming evolve

Live sports has become the crown jewel of the streaming era, but monetizing this content effectively is far from simple. From the complexity of dynamic ad insertion (DAI) to the unmet promise of programmatic buying, sports streaming sits carries enormous opportunities and technical challenges alike.

SVG sat down with Jean Macher, senior director, global SaaS solutions, Harmonic, a company that has spent years building the infrastructure for live sports streams. Harmonic's video business is being acquired by MediaKind, and Macher says the deal remains on track to close in the second quarter, noting the company's latest earnings press release when asked for comment. With the company set to showcase its latest innovations at the 2026 NAB Show, he covers the state of in-stream ad insertion, AI-driven fan engagement, the road to programmatic live sports advertising, and what the streaming landscape might look like by 2030.

In-stream ad insertion has become a major industry priority. What are Harmonic's latest innovations in this space? And how can streamers utilize the latest DAI technologies to better monetize their content?

Live sports is the most valuable inventory in streaming but also the most expensive content; therefore, streamers are looking for incremental monetization that won't disrupt the fan experience. In-stream ad insertion delivers on both fronts and has become a strategic priority.

The latest advances in DAI combine server-side ad stitching with AI and real-time analytics to make ad delivery more intelligent, adaptive, and contextual.

Harmonic's VOS360 Ad SaaS leverages AI to deliver personalized in-stream ads using split-screen formats, such as double-box and dynamic L-bars, keeping viewers engaged during live sports events. AI can identify high- and low-action moments within live games, enabling contextually relevant split-screen ads, overlays, and branded elements to be inserted at optimal times without interrupting gameplay. These data-driven innovations help streamers unlock premium inventory, drive higher CPMs, and maximize yield - all while preserving the live-sports experience that fans expect.

At the upcoming NAB Show, Harmonic will showcase a new production deployment in collaboration with Sportradar, where live-sports-data feeds automatically trigger in-stream ads during games, demonstrating how real-time contextual triggers can further enhance monetization opportunities.

Deeper fan engagement is also at the top of the priority list these days for live-sports outlets. What are Harmonic's latest innovations in this space? And how can advanced sports-streaming features create a richer, more personalized viewing experience? Most important, what impact does that have on monetization/revenue?

Deeper fan engagement has become essential as live sports increasingly drives subscriber growth and retention. At Harmonic, innovation starts with delivering the highest-quality viewing experience with outstanding reliability at massive scale, ensuring pristine video and audio quality with low latency that keeps fans in sync with real-time action. From there, advanced capabilities, such as multiview, allow fans to watch multiple camera angles or games simultaneously, giving them greater control over how they consume live sports.

Harmonic's Jean Macher: Live sports is the most valuable inventory in streaming but also the most expensive content. Streamers are looking for monetization that won't disrupt the fan experience. AI-based technologies are further transforming engagement. Features like AI-powered highlights creation enable rapid clipping and social distribution of key moments, extending audience reach beyond the live broadcast. Voice cloning and personalized audio experiences open the door to tailored commentary options, and automated ad triggering based on live game data ensures that monetization opportunities are aligned with contextual moments in the sports event. Together, these capabilities create a richer, more interactive, and personalized viewing experience.

The impact on monetization is significant. A more immersive and customizable experience increases watch time, reduces churn, and drives higher subscriber loyalty. At the same time, contextual advertising, multiview sponsorship opportunities, and dynamic in-stream ad formats unlock premium inventory and higher CPMs. By combining best-in-class video delivery with AI-driven engagement tools, streamers can deepen fan connection while simultaneously expanding revenue opportunities.

We have yet to see programmatic advertising play a major role in live sports content. Why is that? What's holding it back? What are Harmonic's latest solutions in this space, and how can they be implemented to make programmatic ads a reality in live sports?

Live sports is the most valuable inventory in CTV, and today it is still largely sold through direct deals. Advertisers appreciate the efficiency of programmatic deals and are increasingly looking to buying more live-sports inventory this way. Programmatic also aligns well with the unpredictability of live sports: games shift momentum quickly, unexpected moments drive spikes in viewership, and dynamic inventory can be matched in real time with advertisers looking to capitalize on those high-intensity live-sports moments.

Unfortunately, live-sports metadata are currently missing or inadequate to support programmatic transactions. What's lacking is accurate and rich metadata - at both program and scene level - that can be passed seamlessly into and understood by the broader programmatic ecosystem.

Harmonic is addressing this gap by generating live-sports contextual metadata in the VOS360 Media str
