# Enabling blackout


Follow this procedure if you want to enable the blackout feature in a MediaLive channel.

**To enable blackout**

1. In the channel that you are creating, in the navigation pane, choose **General settings**. 

1.  Set the ad avail mode, if you have not already done so. See [Getting ready: Set the SCTE 35 source—segments or manifest](scte35-getting-ready-source.md). The mode identifies which of all possible events are treated as triggers for blackouts, which determines [when video is blacked out](triggers-for-blackout.md). 

   

1. Still in **General settings**, in **Blackout slate**, in **State**, choose **Enabled**.

1. For **Blackout slate image**, choose the appropriate value:
   + **Disable**: To use a plain black image for blackout.
   + **Avail blanking image**: To use a special image for blackout. In the **URL** field, enter the path to a file in an Amazon S3 bucket. For integration with MediaLive, the bucket name mustn't use dot notation, which means it mustn't use . (dot) between the words in the bucket name. The file must be of type .bmp or .png. Also enter the user name and Systems Manager password parameter for accessing the S3 bucket. For information about this key, see [About the feature for creating password parameters](requirements-for-EC2.md#about-EC2Password).

1. If you want to enable network end blackout (in other words, black out content when network transmission has ended and remove blackout only when network transmission resumes), continue reading. If you don't want to enable it, you have now finished setting up. 

1. For **Network end blackout**, choose **Enabled**.

1. For **Network end blackout image**, choose the appropriate value:
   + **Disable**: To use a plain black image for blackout.
   + **Network end blackout image**: To use a special image for network end blackout. In the **URL** field, enter the path to a file in an Amazon S3 bucket. For integration with MediaLive, the bucket name mustn't use dot notation, which means it mustn't use . (dot) between the words in the bucket name. The file must be of type .bmp or .png. Also enter the user name and Systems Manager password for accessing the S3 bucket. See [About the feature for creating password parameters](requirements-for-EC2.md#about-EC2Password).

1. For **Additional settings**, in **Network ID**, type the EIDR ID of the network in the format 10.nnnn/xxxx- xxxx- xxxx- xxxx-xxxx-c (case insensitive). Only network end events with this ID will trigger blackout.
