When Millions Tune In: Server-Guided Ad Insertion for Live Sports Streaming

on YouTube ↗17m

" summary

JioHotstar moves beyond SSAI to a Server-Guided Ad Insertion (SGAI) design that keeps one common stream while enabling per-user ads via a manifest interceptor client library and middleware, solving cohort explosion, CDN cache churn, and programmatic precision. Real-world engineering tackles a thundering herd of 55 million concurrent users, millisecond-level ad decisioning, lightweight on-device stitching, tuned jitter and prefetch strategies, and tradeoffs between CDN cacheability and per-impression targeting.
