Enable SMPTE 2038 - AWS Elemental Live

Enable SMPTE 2038

You must set up the input to ingest the SMPTE 2038 ancillary data.

Note

The information in this section assumes that you are familiar with the general steps for creating an event.

To set up the event to look for ancillary data in SMPTE 2038

Follow these steps for both types of handling—extract and use, and passthrough.

  1. Speak to the content provider to obtain information about the SMPTE 2038 ancillary data in the source:

    • Find out which of the four types of ancillary data are in the SMPTE 2038. If the ancillary data includes captions, find out which format of captions is present.

    • Find out whether the SMPTE 2038 includes custom data. Elemental Live can ingest custom data only if it is set up in a DID/SDID pair. It can't ingest data that's set up in a DID/DBN pair.

      Obtain the values of the DID and SDID for all the custom data pairs.

      Obtain a description of the data in each pair.

  2. On the Elemental Live web interface, display the details for the event that you want to set up.

  3. In Input, make sure you have set the Input type field to one of the following. These types are all valid for TS inputs:

    • Network Input

    • File Input

    • HLS File Input

    • HLS Network Input

    • SMPTE 2022-7 Network Input

    The Prefer SMPTE 2038 field appears in the Advanced section of the Input section.

  4. In Input > Advanced, set Prefer SMPTE 2038:

    • Checked – You should choose this option if the source content contains SMPTE 2038 ancillary data. If the content provider has included SMPTE-2038, they intend for you to use it.

    • Unchecked – If you do not want Elemental Live to look at the SMPTE 2038, uncheck this field. Choose this option if the source content doesn't include SMPTE 2038 ancillary data. Elemental Live looks for ancillary data in the native TS. Even if a SMPTE 2038 PID is present, Elemental Live ignores that PID.
