The Essential Guide to SCTE-35

SCTE-35 is the backbone of ad insertion and program control in modern video streaming, but few people outside of broadcast engineering truly understand how it works. This essential guide covers everything: what SCTE-35 is, where it came from, the key marker types, how cues are carried in MPEG-TS, HLS, and MPEG-DASH streams, and how platforms use it to trigger dynamic ad insertion, program boundaries, and regional blackouts. It also walks through Bitmovin’s own SCTE-35 support for both live and VOD encoding workflows.
