SCTE-35 Passthrough or Removal

You can set up the AWS Elemental MediaLive channel so that SCTE-35 messages from the input is passed through (included) in the data stream for the following outputs:

  • Outputs in an Archive output group.

  • Outputs in an HLS output group.

  • Outputs in a UDP output group.

Alignment with Video

The PTS of the SCTE-35 message is adjusted to match the PTS of the corresponding video frame.

Passthrough Is at the Output Level

SCTE-35 passthrough or removal applies at the output level. The messages are passed through or removed only in a specific output. The default behavior (if you do not change the configuration fields) is to remove the messages.

The Procedure for Archive

  1. In the channel that you are creating, find the Archive output group that contains the output that you want to set up.

  2. Choose that output.

  3. In PID settings, complete the following fields:

    • SCTE-35 control: Set to Passthrough.

    • SCTE-35 PID: Leave the default PID or enter the PID where you want the SCTE-35 messages to go.

  4. If appropriate, repeat for other outputs in this or other Archive output groups.

All SCTE-35 messages from the input are included in the data stream of the outputs that you have set up.

The Procedure for HLS

  1. In the channel that you are creating, find the HLS output group that contains the output that you want to set up.

  2. Choose that output.

  3. In PID settings, complete the following fields:

    • SCTE-35 behavior: Set to Passthrough.

    • SCTE-35 PID: Leave the default PID or enter the PID where you want the SCTE-35 messages to go.

  4. If appropriate, repeat for other outputs in this or other HLS output groups.

All SCTE-35 messages from the input will be included in the data stream of the outputs that you have set up.

The Procedure for UDP

  1. In the channel that you are creating, find the UDP output group that contains the output that you want to set up.

  2. Choose that output.

  3. In PID settings, complete the following fields:

    • SCTE-35 control: Set to Passthrough.

    • SCTE-35 PID: Leave the default PID or enter the PID where you want the SCTE-35 messages to go.

  4. If appropriate, repeat for other outputs in this or other UDP output groups.

All SCTE-35 messages from the input will be included in the data stream of the outputs that you have set up.
