DASH EventStream elements are used to signal all SCTE-35 time_signal or
splice_insert markers present in the source. When you configure the ad markers to
use the XML signaling, all the SCTE-35 markers parameters will be described through
multiple nested XML elements inside the Event element. When you configure the Ad
markers to use the Binary signaling, all the SCTE-35 markers parameters will be
described through a Signal element including a binary base64-encoded representation
of the SCTE marker, nested inside the Event element.
For more information about the XML and Binary signaling schemes for DASH, see
section 5.5.2 of the DASH
Industry Forum IOP Guidelines v5
The following table describes how to enable DASH ad markers in MediaPackage.
To enable DASH ad markers when creating or editing an origin endpoint, in the MediaPackage console, under the DASH manifest settings, SCTE configuration, Ad markers, choose XML or Binary.
Example DASH manifest showing SCTE-35 EXT-X-DATERANGE
signaling
This example shows a DASH manifest generated by MediaPackage using XML signal approach to
signal a splice_insert event in the live stream.
