5.3 Ad hoc from center

Ad hoc from center is a mechanism where Ad hoc changes to a Customizable or Ad hoc Item on a Publisher

iCOMPEL, are published to all Subscribing iCOMPEL players when those subscribers poll the Publisher for updates.

This differs from changing a normal media item on the publisher and letting the normal subscribe process update content on

subscribers, because it uses the Ad hoc mechanism to update the contents, so users do not need to edit a Layout. The

Ad hoc entry page is only visible on the publisher iCOMPEL.

Subscriber iCOMPEL players generally check for updates to the main channel infrequently as the does not change often.

However, the iCOMPEL can be set to check for Update From Center Ad hoc items more frequently.

Supported Media

The iCOMPEL supports Update from Center for Ad hoc Text and Schedule Override items.

Ad hoc text

When a user selects an Ad hoc from center Schedule Override on the Publisher, the selected override runs on both

the Publisher and the Subscribers.

Note: Ad hoc text will only be updated each time it is drawn to the display. So you need to set the text to display, for

example, for a minute instead of indefinitely.

Ad hoc Schedule Override

When a user selects an Ad hoc from center Schedule Override on the Publisher, the selected override runs on both

the Publisher and the Subscribers.

To restore the original Schedule on the iCOMPEL, either select Normal Schedule from the Ad hoc page or re-publish the

channel.

Using Update From Center

When you create an Ad hoc item that can be used with the Ad hoc from center mechanism, you can set the item's

scope as follows:

Local

(Default) Ad hoc text items behave as normal. Ad hoc users can log in and change the

contents for each iCOMPEL.

Remote

This Ad hoc item will only be visible to Ad hoc users on the Publishing iCOMPEL.

Changing the Ad hoc item here causes the Ad hoc item to be updated on all Subscribers

as well as the Publisher.

Update From Center Polling Interval

On a Subscriber iCOMPEL, the Channel Management page shows the option Update From Center Poll Interval. This

determines how often the Subscriber iCOMPEL will poll the publisher for changes in update from center actions.

If update from center changes are made on the Publisher, then the Subscribing iCOMPEL is updated within this time

period.
