Screen Sync Plugin
The Screen Sync Plugin synchronizes multiple players to play the same or different content in a coordinated manner across multiple screens. This lets you create video walls, synchronized displays, or interactive multi-screen setups.
Prerequisites
Section titled “Prerequisites”- An active viewneo subscription that includes the Screen Sync Plugin
- Multiple registered viewneo players
- All players must be on the same local network
Operating Modes
Section titled “Operating Modes”The Screen Sync Plugin supports three different modes:
| Mode | Description |
|---|---|
| Splitted Content (Video Wall) | One piece of content is split across multiple screens (e.g., 2×2 video wall) |
| Synchronized Content | All screens display the same content simultaneously |
| Multi Content | Each screen shows different content, coordinated by a controller |
The Controller Principle
Section titled “The Controller Principle”In all modes, a controller player manages the timing of the other players. The controller dictates when which content is played.
The controller does not need to be connected to a screen — it serves solely for control purposes. The connection between controller and players is established via Events.
Mode 1: Splitted Content (Video Wall)
Section titled “Mode 1: Splitted Content (Video Wall)”This mode lets you create a video wall where one piece of content is distributed across multiple screens — e.g., a large video on 4 displays (2×2).
- Use 5 players for a 2×2 video wall: 4 players for the screens + 1 controller
- Prepare the content so it’s split into 4 parts — each part corresponds to one screen section
- Create a separate playlist for each of the 4 players with the respective content section
- Create an Event from the controller player that synchronizes the 4 players
Checking the Connection
Section titled “Checking the Connection”After event creation, you can verify in the device overview whether the connection between controller and players was established:
- Closed chain: Connection successful
- Green dot: Device is online
Mode 2: Synchronized Content
Section titled “Mode 2: Synchronized Content”All screens play the same content simultaneously.
- Assign all players the same playlist
- The controller dictates the timing of when which content is played
- Create an Event that synchronizes the players with the controller
Mode 3: Multi Content
Section titled “Mode 3: Multi Content”Each screen shows different content, coordinated by the controller. This enables interactive setups with touch displays, for example.
Example: Tablet + 2 Screens
Section titled “Example: Tablet + 2 Screens”A tablet and 2 screens are synchronized. When a visitor selects content via touch on the tablet, both screens show their respective assigned content.
- Create a separate playlist for each device with the respective content
- Create an Event on the controller that controls when the touch content is displayed on the tablet
- Create an Event in the tablet playlist that controls the content on both screens upon interaction
