# Getting Ready: Setting the Ad Avail Mode
<a name="getting-ready-setting-the-ad-avail-mode"></a>

Read this section if you want to support any of these features:
+ Manifest decoration for all outputs. 
+ Ad avail blanking for all outputs. (Note that this section does not apply to the blackout feature.) 

If you have several outputs and want to do manifest decoration or ad avail blanking on some outputs and not others, you have to set up two different profiles or jobs.

**Note**  
You do not have to read this section if you *are* doing Blackout image insertion but you are not doing ad avail blanking or manifest decoration.

**Set the Ad Avail Mode**

You must set the Ad Avail mode. The Ad Avail mode applies to all outputs: it cannot be set differently for individual outputs.

1. In the Profile or job screen, click Advanced Avail Controls (in the Input section towards the top of the screen):

1. In Ad Avail Trigger, choose the desired mode. This mode identifies which of all possible “ad avail” events are actually to be treated as “ad avails.” This distinction comes into play in manifest decoration and ad avail blanking. For more information, see [Manifest Decoration](manifest-decoration.md) and [Ad Avail Blanking and Blackout](ad-avail-blanking-and-blackout.md). 

   Typically, you select the mode to match the type ID that you already know the input is using to indicate “ad avail” events. 
   + **Splice Insert** mode. Select this mode if the input uses splice inserts to indicate ad avails. The input may also contain messages for other events, such as chapters or programs.
   + **Timesignal with APOS **mode. Select this mode if the input contains time signals of segmentation type Placement Opportunity. The input may also contain messages for other events, such as chapters or programs. 

The following table specifies how a message (containing a specific combination of message type and segmentation type) is treated, depending on the mode that is specified. Each message is treated as either an ad avail, a non-ad avail, or as “other."
