SegmentationDescriptor

The segmentation_descriptor message can contain advanced metadata fields, like content identifiers, to convey a wide range of information about the ad break. MediaTailor writes the ad metadata in the egress manifest as part of the EXT-X-DATERANGE or EventStream ad marker's SCTE-35 data.

segmentation_descriptor messages must be sent with the time_signal message type.

See the segmentation_descriptor() table of the 2022 SCTE-35 specification for more information.
