Smil player supports the synchronization of multiple devices within the same group connected to the synchronization server.
There are two things you have to set up. First, provide necessary parameters to each device in applet settings and then mark which regions you want to synchronize in the smil file.
Definition of the region with synchronization enabled
Add parameter sync="true" to a region you want to sync.
<region regionName="main" left="0" top="0" width="1920" height="1080" z-index="1" sync="true"/>
Applet settings setup
smilUrl: URL to your actual smil file
syncServerUrl: URL to the synchronization server. Default sync server in cloud is at https://applet-synchronizer.signageos.io/ but it's strongly recommended to use a local-hosted sync server for the best performance.
syncGroupName: identifies which devices should be synced together. All of the devices within the same group will be synced together, even if they are not in the same network. If no syncGroupName is specified, smil player will use the default one.
