Dynamic content insertion into live streams across the 3 main streaming formats
summary
Claims a production system that inserts regional content into HLS, multi‑Period DASH, single Period DASH and Smooth Streaming from one global playout and a single encode, using SCTE-35 signalling and a manifest manipulator plus a Segment Rewriter that swaps VOD segments on the fly. Details include encoder/segment alignment, three small duration corrections to avoid a flash‑of‑live, caching and MP4 box rewriting for compatibility, optimized origins for ~8–11 region variants, and successful live deployments.
