Synchronization in BrightWall Presentations

You can create and publish simple looping playlists of videos that are synchronized across multiple players and displays with BrightWall. You can also use Synchronize commands within interactive playlists to synchronize almost any player function, including content updates, executing serial or network commands, reading or writing files, etc.

Synchronization uses UDP messages to coordinate playback on multiple players that are on the same local network: The leader player sends sync messages to the follower players, and the followers listen for sync messages to coordinate playback with the leader.

The difference between a Synchronize command/event and a UDP command/event is that the Synchronize feature pre-loads media. Players cannot pre-load any state other than image/video files (i.e. audio, text, etc.), so it is only possible to use Synchronize events with image/video states. If you want to synchronize states other than image/video, you will need to use UDP commands/events; however, you will not be able to achieve the same level of accuracy as when using a BrightWall playlist or Synchronize commands/events.

Zone Message events and commands allow you to synchronize a state among multiple zones in a single presentation. 

Notes:

• Synchronization is supported over wireless connection on BOS 8.0.146 and newer (older firmware may send/receive sync messages but may not be synchronized). For more reliable synchronization, use a wired network connection.

• If the player has more than one active network connection, make sure the players can only communicate between each other over one of the connections, otherwise duplicate sync messages may be sent/received, causing disruption of sync

• You cannot synchronize BrightSign players that belong to different product lines.

• When using players with different BOS versions (not recommended), make sure the leader (Screen 1 in a BrightWall) has the same or older BOS version as the follower players.
