What can be synchronized on BrightSign players?

Follow Avatar BrightSign Support Manager

Last Updated: April 13, 2021

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. 

Notes:

  • Synchronization is supported over Wireless connection on firmware/OS 8.0.146 and newer
    Older firmware may send/receive sync messages over wireless but it is not guaranteed to be synchronized
  • 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 firmware versions (not recommended), make sure the Leader/Master (Screen 1 in a BrightWall) has the same or older firmware version as the Follower/Slave players.

    Hi, can I synchronize only audio files, for a multi-zone audio application?

    You can coordinate playback of audio files. You can send commands from one device to another so they are playing together. You can use a udp or other command to make sure they are triggered at the same time.

    I've been having a problem with synchronize to do a video wall with crestron using 3x XD1230 models. My project is Live tv as my home and a video wall. Crestron is connected via Ethernet we use a udp event and I add the synchronize. I know the video wall works cause I can make it work without crestron but with crestron I can go to the video wall but I cant go back home to live tv, we try to trouble shoot and it seem it can only go back home if we remove the sync command but without the synchronize command we cant get the video wall. I'm using default port for communicating with crestron. I'm using the latest firmware Help!

    Hi Francis,

    Please send the presentation (the .bpf file) that doesn't work to support@brightsign.biz along with the description of the problem. Thanks.

    Hi,

    can I syncronize two brightsign for only certain video during the day? For example, from 8:00 to 11:59 the players show indipendent content but at 12:00 they show the same syncronized video. Is it possible? How? I would use Enhanced Sync or sync but not videowall.

    thanks

    Yes, you can do this. You can use a time schedule event inside the prolject to switch to a specific video at 12. You can attach a link synchronize command to the time schedule transition itself.  On the slave unit you just listen for the sync event. If you have a master and slave project already we can show you how to make changes to it.

    Hi,

    I am try to get 2 commands on a Brightauthor projector? 

    First command is a Link, Synchronise and key word and second command is Link, Zones and key word.

    As soon as i add the sync to the zone the BS player get the red error flashing light.

    Is it possible to have a master BS with these two command?

    Thanks

    I want to synchronize three video players

    One will be master and other two will be slaves

    I want to start the master on network with UDP/TCP 

    Master will take care of sync.

    Is it possible? what is the sync accuracy

    Yes is possible, and the sync accuracy is very hight. I use its to sync three player that control three sending card of a ledwall ring over 10000px width. You can sync one master with N slaves, all will be on the same network

    I'd like to use Brightauthor to audio sync two or three HD models using an ethernet switch.  I've had good experience with this technique for mp4 video-only in the past, but I'd like to use four channels of .wav audio-only files to play in tight synchronization.  I tried encoding ac3 but did not like the compressed sound quality.  What is the best way to tightly synchronize for .wav audio to avoid "doubled percussion" etc.  Even a few milliseconds out really messes-up a song!

    I sync three players that control three sending cards for a ledwall ring that is over 10000 pixels wide using its functionality.
