This feature is often used with Sync Groups to swap out a single design for one face even though these faces are being administered by the same loop.
| Face 1 | Face 2 | Face 3 | |
|---|---|---|---|
| Booking Line 1 | Design 1 | Design 1 | Design 1 |
| Booking Line 2 | Design 2 | Design 2a | Design 2 |
Booking Lines instead of Bundles
The value of bundles is that restrictions and other business rules can be applied to their contents. However, if one face needs to play one file, and another face must play a variant of the same file, the best practice is to give each design a separate booking line.
Why?
Only one bundle can be scheduled at a time and, of course, the contents in that bundle will be selected dynamically. Booking lines allow digital schedulers to associate one design with a period rather than a bundle, which typically contains more than one design.
Design Variations and Sync Groups
Obviously, if Design Variations are used in conjunction with sync groups, all the faces must have the same number of designs/spots lasting the same period of time otherwise the displays will not function in step.
