PPV Advertising Window Defaults
By default, the advertising window starts 15 minutes before an event starts and ends
45 minutes after an event starts. These values are called the start offset and the end
offset. Cisco suggests that you adjust these values if you frequently have events that
are less than 60 minutes long.
Before you adjust these offsets, you must identify the length of the shortest event
Before you adjust these offsets, you must identify the length of the shortest event
that you will advertise. The length of your shortest event is your minimum event
interval. Use the minimum event interval and the following guidelines to determine
the new default values for your offsets:
•
•
The total offset time (start offset plus end offset) must not exceed your minimum
event interval. For example, if your shortest event is 30 minutes long, then the
start offset plus the end offset must not exceed 30 minutes.
•
For IPPV events, the purchase window cannot start before the advertising window
starts.
•
The advertising window must end at least 5 minutes before the end of the event.
The following table shows two examples of minimum event intervals and identifies
acceptable default values for the start offset and the end offset:
