Create your zones and name the leader and follower zones.
Make all of the zones interactive by selecting Advanced in the top right corner, as shown in Image 1a or toggling on Interactive in BABrightAuthor:connected versions before 1.47.2, as shown in Image 1b.
Select the leader zone and add the content elements to synchronize.
Add your timeout and transition commands to the content.
Add UDP commands to the content with indications like “start” and “end” that can be used to trigger transitions as shown in Image 2.
Select the timeout and transition commands on the initial content, and add the Link command and Synchronize command parameter under Advanced. Enter whatever Keyword you have chosen to start the content.
Do the same for the content that should play after the initial content. Use the keyword “end” (or whatever keyword you have selected) in the final command that returns you to the initial content. See the image below.
Select all of the content and commands and copy them to each of the follower zones. Delete the events, since only Synchronize events are needed in the follower zones.
Now add Synchronize events to all of the content in the follower zones and specify the necessary Keyword (for example, “start” or “end”). Your presentation is now ready to publish.
