Converting Nielsen watermarks to ID3 - AWS Elemental Live

Converting Nielsen watermarks to ID3

If one or more inputs in an event includes Nielsen watermarks in the audio, you have the option to set up the event to convert those watermarks to ID3 metadata. These watermarks are part of the measurement and analytics capabilities supported by Nielsen.

This option applies only in the following scenario:

  • One or more inputs in your event includes Nielsen watermarks in the audio.

  • Your event has at least one output group that can include the Nielsen ID3 tag. For example, an HLS output group.

  • You know that at least some of your playback devices implement the Nielsen SDK. This SDK provides functionality to handle the ID3 tags.

Converting the watermarks to ID3 tags doesn't remove the original watermarks. Outputs where you include the ID3 tags will contain both the watermark and the ID3 tags. Outputs that don't include the ID3 tags will contain only the watermark.

You can't remove the watermarks from the audio, but if your playback devices don't implement the Nielsen SDK, the devices ignore the watermarks.

To set up watermarks as ID3 tags
Note

The information in this section assumes that you are familiar with the general steps for creating an event. It also assumes that you have already set up the output groups that will contain the ID3 tags.

  1. On the Event page of the web interface, go to the Nielsen Configuration section. This section is before the Global Processors section.

  2. Set the fields to enable and configure the feature:

    • Enable Nielsen PCM to ID3 tagging: Choose the check box to enable the feature.

    • Distributor ID: This field appears when you enable the feature. Optionally, enter the distributor ID that you obtained from Nielsen. If you enter an ID here, it is added to the ID3 metadata along with the source ID (SID) that is always in the source watermark.

    Information following these fields describes the supported Nielsen SDK and the vendor ID that ID3 tags will use.

  3. Go to the output group where you want to include the ID3 tags. The output group must be an Archive, Apple HLS, or UDP/TS group. You can set up one or more output groups to include ID3 tags.

  4. If the output group doesn't have an output, choose the Add Output button. An Outputs section appears.

  5. In the Outputs section, take the appropriate action:

    • For an Archive output group, in Container, choose MPEG-2 Transport Stream. This is the only type of container that supports ID3 tags.

    • For an Apple HLS output group, in Segment Type, choose TS. This is the only segment type that supports ID3 tags.

    • For a UDP/TS output group, you don't need to set anything.

  6. Open the PID Control section to see more fields, including Nielsen ID3.

  7. In Nielsen ID3, choose the check box to enable passthrough in this output.
