Nielsen watermarks
You can setup AWS Elemental MediaLive to create new Nielsen watermarks and insert them in the output audio. Typically, only content and distribution providers use Nielsen watermarks. If you're not working with The Nielsen Company to implement watermarks, you don't need to read this section.
If your content already contains watermarks, you might choose to convert them to ID3 metadata and include that metadata in the output. For more information about passthrough and conversion to ID3, see Converting Nielsen watermarks to ID3.
