Getting ready: Setting the ad avail mode

Read this section if you want to support any of the following 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 you want to do manifest decoration or ad avail blanking on some of the outputs and not on others, you have to set up two different profiles or events.

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 uniquely for individual outputs. To set up the Ad Avail Mode, do the following.

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

2. In Ad Avail Trigger, choose the desired mode from the drop-down menu. This mode identifies which of all possible “ad avail” events are treated as “ad avails.” This distinction comes into play in manifest decoration and ad avail blanking. For more information, see Manifest decoration and Ad avail blanking and blackout.

   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 might also contain messages for other events such as chapters or programs.

   • Time Signal with APOS Mode. Select this mode if the input contains time signals of segmentation type placement opportunity. The input might 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.”

Read across the first three columns to identify a combination of mode, the message type and the segmentation type. Then in the last three columns, identify how Elemental Live handles that combination.
