Overview

To synchronize videos across players in BrightAuthor:connected, you must ensure that both the presentation video zones and the player clocks are synchronized (these principles are the same BrightAuthor).

To make videos synchronize inside a BrightSign player, you must create The Link Synchronize advanced command and Synchronization Event are used in BrightAuthor:connected to synchronize playback across zones in a single player or between players, and using these two together establishes a leader/follower relationship between those zones.

To sync media across zones in groups of networked players, the presentation zones and the player clocks must both be synchronized. In this scenario, a leader/follower relationship is established between zones, and BrightSign player clocks are synchronized through the Presentation Properties settings. This creates a leader and follower relationship between players.

Video synchronization works by means of a synchronization command issued in the transition to the video state. The state proceeding the synchronized can be any of the available state types.

Synchronizing Presentation Zones across Players

To synchronize video states inside of video zones in a BrightSign presentation, you must send a Link Synchronize message in a video leader zone and create receive that message in an event to that will listen for that link synchronize message in follower zones. If this is established, the synchronization message can be received by one or more video zones that are listening for that message in the Synchronize Event.

To synchronize video players that are on the same local network, you need to create two presentations. The leader presentation must have a presentation setting that defines that player as a synchronization leader, and the other presentations must be set as followers. Then all presentations will be able to sync accurately based on the clock and video player sync settings.

Creating the Leader Presentation

...

Create the leader presentation (make sure to toggle Interactive on the top right).

...

To do this:

Creating the Leader Zone Message

1. Create a presentation with content inside of zones. Make sure to set the toggle to Interactive on the top right.

2. Select the transition event in the leader zone in your presentation. It may be helpful to include “Leader” and “Follower” in the zone names.

3. Add a transition event to the content you want to display first, then drag that event to the other content in the presentation.

4. In Event Properties > Advanced, select Add Command.

5. Select the Link command and select the Synchronize command parameter.

   

6. Toggle the down arrow to enter a Keyword. This keyword will be used to trigger follower players to start displaying display content.

7. In Presentation Settings > Interactive > Synchronization, select Enable enhanced synchronization and choose Master. This will enable synchronization of player clocks.

8. Publish Save the presentation.

Creating the Follower

...

Zone Event Listener

1. Create Select the follower presentation (make sure to toggle to Interactive on the top right)zone.

2. Add a Synchronize event to the content you want to display first, then drag that event to the other content in the presentation.

   

3. In the Event Properties pane, under Specify synchronization keyword, enter the Keyword you selected in step 5, above. When the follower presentation zone receives this keyword from the leader zone, it will start to play.

4. Do this for all of the follower zones in the presentation then select Save. You can also select Save as to save the presentation with a different name for additional players (for example “Player 3 follower presentation”).

5. If you are publishing from a single XC5 player, you can then select Publish to publish the synced presentation. Otherwise, use the following section to synchronize the clocks of the players that will display your presentation.

Synchronizing Presentation Clocks

To synchronize multiple BrightSign player clocks on the same local network, the leader presentation must have a presentation setting that defines that player as the leader, and other presentations must be set as followers. To do this:

1. Select the transition event leading to the Video State in the leader zone.

2. In Presentation Settings > Interactive > Synchronization (under the Networking tab), select Enable enhanced synchronization and choose Slave Master.

3. Add Select a synchronize transition event leading to listen for the Keyword you selected in step 5, above.the Video State in a follower zone in your presentation.

4. In Presentation Settings > Interactive > Synchronization, select Enable enhanced synchronization and choose Slave.

5. Do this for all the follower zones in your presentation, then Save and Publish. You can also select Save as and Publish the presentation with a different name for additional players (for example “Player 3 follower presentation”)

And by receiving the Sync message in the video state of Slave (Follower) zone(s).

Synchronizing Presentation Zones within a Player

As of BrightAuthor:connected 1.19.3 and BOS 9.0.101, you no longer need to use Link Zones (Jam sync) to synchronize presentation zones on a player. Instead, when you want to synchronize zones, use Link Synchronization and it’s follower component called the Synchronization Event. This method only uses software synchronization, not hardware (clock) synchronization.

To do this:

1. Create your zones and indicate in the name which zone is the leader and which are followers.

2. Make all of the zones interactive by setting the Interactive toggle to on (in the top right corner).

3. Select the leader zone and add the content elements to synchronize.

4. 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.

5. 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.

6. 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.

7. 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.

8. 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.

Synchronizing Presentation Zones across Multiple Players

To synchronize clocks in multiple video players on the same local network, you should have multiple presentations. The leader presentation must have a presentation setting that defines that player as the leader, and other presentations must be set as followers. These instructions assume that you have set up the necessary timeout and transition commands in your zones and added the Link Synchronize advanced command (as described in steps 1-6 in the section above).

To do this:

1. Select the leader presentation.

2. In Presentation Settings > Interactive > Synchronization (under the Networking tab), select Enable and choose Leader.

3. Select a follower presentation.

4. In Presentation Settings > Interactive > Synchronization, select Enable and choose Follower.

5. Do this for all follower presentations, then Save and Publish. You can also select Save as and Publish the presentation with a different name for additional players.
