5.19 Using the XStudio Relay Queue Maintenance Dialog
When a Start Play Task that uses a Cart Rotation List is executed for the first time, XStudio invisibly
adds the task to its relay queue manager. The relay queue manager is responsible for rotating the
items in the Cart Rotation List for those tasks that have multiple cart numbers assigned to the list.
When the task is executed a second and subsequent times while XStudio is running, cart number
rotation occurs. Carts that are missing or out-of-date (if Enforce Cart Dates is enabled) are skipped.
When XStudio is closed, the relay queue manager discards all items in the queue. When XStudio is
started again, the relay queue manager will be empty and each Start Play Task using the Cart Rotation
List will start with the first item in the list. As these types of tasks are executed, they are added to the
relay queue manager.
Sometimes, you might need to modify a particular task's rotation list or change the item that will be
next-to-play when the task is next executed. For instance, there might be a weather event in the area
and you want to add an announcement to run every other time a liner is called by your satellite
programming service. The Relay Queue Maintenance Dialog is used for this purpose - temporarily
adding or removing carts in the relay queue for a given task.
Only tasks that have been executed at least once during the current XStudio
session will appear in the active relay queue items list and be available for
maintenance. For any tasks that have not yet executed, you can edit the master
task record in the Automation Database Maintenance dialog if you wish to
change the cart rotation list. However, unlike changes made in the Relay Queue
Maintenance Dialog, which are in effect only until XStudio is restarted, changing
the master task record is considered a permanent change.
Tasks of this type are most often associated with Satellite mode operations and the cart numbers in
the Cart Rotation List often contain cart macro characters, including the Current Voice (also known as
Voice Number). For this reason, you can also use the Relay Queue Maintenance Dialog to change the
Current Voice value on-the-fly rather than with the normal methods (using a log Directive or Set Voice
task).
To display the Relay Queue Maintenance Dialog, select the XStudio main menu item View |
Automation Info | Relay Queue Maintenance. The dialog will be similar to the example shown.
