Using the BrightWall feature in BrightAuthor (versions 3.8.0.x and later), you can create and publish simple looping playlists of videos that are synchronized across multiple players and displays. You can also use Synchronize commands within interactive playlists to synchronize almost any function that players can perform, including content updates, executing serial or network commands, reading or writing files, etc. See this FAQ to decide which synchronization option to use.
Synchronization utilizes UDP messages to coordinate playback on multiple players that are on the same local network: The master player sends sync messages to the slave players, and the slave players will listen for sync messages to coordinate playback with the master.
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.
Furthermore, Zone Message events and commands allow you to synchronize a state among multiple zones in a single presentation.
- Synchronization is not supported over Wireless.
- You cannot synchronize BrightSign players that belong to different product lines.
- When using players with different firmware versions (not recommended), make sure the Master (Screen 1 in a BrightWall) has the same or older firmware version as the slave players.
