What is Server-Guided Ad Insertion (SGAI)?

Manifest creation: The server generates a manifest with SCTE-35 markers outlining where and when ad breaks occur.
Ad request: When the viewer reaches an ad break, their device sends a personalized request to the ad server using targeting data.
Ad playback: The device handles ad insertion and playback, ensuring the advertisement and main content flow seamlessly without delays.

Simplicity with no long manifests or DVR window limitations.
Unmatched scalability — no central stitcher that could impact all viewer sessions.
Guaranteed ad delivery — the player only requests inventory when the ad break will actually be played.
Enhanced analytics — complete information on viewer, device, and playback session.
Real-time flexibility and low latency — no need to perform ad-decisioning calls ahead of time.
Cost-effective — higher fill rates and rendering rates.
