SSAI LIVE - SCTE35

For accurate ad-insertions or replacement, the type and the timing of the SCTE35 marker is of high importance and must reach the following requirements:

• Following the SCTE35 specification, see the doc

• CUE-OUT marker with the duration of the ad break.

• The ad marker must be present in every HLS rendition/submanifest/playlist.

• The ad marker must be present for at least 5sec. before the ad break should start.
