Window
Purpose
Buy (GBAM)
Window
This window defines the period of time that the PPV service will
attempt to verify IPPV event purchases. If the PPV service verifies the
purchase, the subscriber will see the event. (The Buy window uses a
Global Broadcast Authenticated Message [GBAM] to verify a
purchase.)
Cancel Window This window defines the period of time that a subscriber may cancel an
IPPV event purchase.
Window Relationships
There are some timing requirements that you must follow when setting up PPV
windows. If you do not follow these requirements, then subscribers may not be able
to purchase PPV events successfully. For example, if you do not define an
Advertising window correctly, then the Purchase barker will not appear when
subscribers tune to the PPV service channel. In this case, subscribers are unable to
purchase the event. Or, if you do not define the event itself correctly, then the event
will not appear as expected.
In examining the window relationships in the following illustration, remember that
In examining the window relationships in the following illustration, remember that
the billing system defines these windows when it sends the event definition to the
Application Server. Therefore, in most cases you should not need to define an event
(although you can do so manually if necessary.) You can view the Set Up PPV Event
window to view the window definitions for an event.
