Live ad personalization depends on more than choosing the right creative. It also needs to be ready in the right quality in time. Learn how the Dolby OptiView Ad Engine conforms ads within the ad-break window, enabling more personalized ad experiences while maximizing ad revenue.

Spoilers kill the live sports moment. Discover why viewer synchronization matters more than latency alone, and how to take control of both.

An in‑depth conversation with Dolby’s Michel Roofthooft explores how Dolby OptiView came together, and why Server‑Guided Ad Insertion matters. Low latency, personalization, and streaming architecture all come into play.

Server-Guided Ad Insertion (SGAI) is redefining how personalization works in digital TV advertising by shifting the ad decision to where viewer-level signals actually exist, while keeping device workloads light and playback seamless. This approach finally makes it possible for publishers and advertisers to deliver relevant, scalable, and stable personalized ad experiences at the moment they matter most.

Ad insertion isn’t just a technical choice; it’s an economic one. Each architecture defines a different balance between cost and yield. Client-Side Ad Insertion (CSAI) minimizes infrastructure expense but limits coordination and scale. Server-Side Ad Insertion (SSAI) improves reliability and ad completion but is expensive and offers weak personalization. Server-Guided Ad Insertion (SGAI) rebalances control between server and player, delivering SSAI-quality playback at far lower cost than SSAI while restoring real-time targeting and client-side measurement.

SGAI’s efficiency comes from architectural simplicity: one shared manifest, just-in-time ad calls, and player-level beaconing. As the article shows, the result is higher CPMs, stronger fill and match rates, and lower total cost of ownership.
