Windows
PPV services use six different types of windows to offer events to subscribers. Some
windows are used for both RPPV and impulse pay-per-view (IPPV) events, and
some are used for IPPV events only. The following table describes the different
windows and the associating PPV event.
Type of Window
Purpose
Event Window
This window defines the period of time that video is shown
on the PPV service channel. The event’s start time and length
determine this time period.
Marketing
Window
This window defines the period of time that the PPV service
can advertise the event. During the Marketing window, a
Purchase Prompt barker appears when the subscriber sets a
reminder or VCR timer for the event. This also allows
subscribers to purchase an IPPV event from the IPG.
Important: The Marketing Window should be at least as
long as the number of days of IPG data you provide
(typically seven days).
Advertising
Window
This window defines the period of time that the Purchase
barker appears when the subscriber is tuned to the PPV
service channel. Each PPV service may have only one
Advertising window open at a time.
Preview Window
This window defines the period of time that a subscriber may
view the IPPV event on the PPV service channel without
purchasing the event. During this time, if the subscriber has
not purchased the event, the Preview barker appears. When a
subscriber purchases the event, the event appears.
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.
