<a name="ad-avail-blanking-and-blackout"></a>

You can turn on one or both of the following features to blank out the content associated with a SCTE-35 event:
+ “**Blackout**”: Blank out the content for other types of SCTE-35 messages such as chapters and programs.
+ “**Ad avail blanking**”: Blank out the content for a SCTE-35 message that is considered an “ad avail” (according to the mode, [Getting ready: Setting the ad avail mode](getting-ready-setting-the-ad-avail-mode.md)).

In both features, the handling is one of the following.
+ Replace the video content associated with the event with an image you specify or with a black image.
+ Remove the audio associated with the event.
+ Remove the closed captions associated with the event.
