Contextual metadata enrichment
In an AWS Elemental MediaLive channel, you can enable contextual metadata enrichment. This feature embeds AWS Elemental Inference query parameters into outgoing SCTE-35 cue-out markers. When enabled, MediaLive appends additional segmentation descriptors to SCTE-35 cue-out messages. Downstream consumers can then query Elemental Inference for contextual metadata. Examples of downstream consumers include ad-decision systems such as AWS Elemental MediaTailor.
Important
The PTS and timebase values in these splice descriptors might differ from the PTS format
that your output uses. Downstream systems must use these values only to query
the Elemental Inference GetMetadata API.
For the binary format of the enrichment descriptors, see AWSE SCTE-35 format.
