This page / section pertains to BrightSign Author, our latest app for authoring and managing content and players. For the legacy BrightAuthor Classic app, refer to our [Legacy Docs](docId\:i5zF53DX56wdWDFHlRot1).
:::

The below applies to versions of BrightSignOS and BrightSign Author (BrightAuthor\:connected) earlier than 9.0.75 and 1.16.0, respectively.

To synchronize video states in zones in older versions of BrightSign presentations, and on players with older operating systems, you must send a **Link Synchronize** message in a leader zone and receive that message in an event that will listen for that message in follower zones. You must also synchronize player clocks.

# Sync Zones on a Single Player

## Create the Leader Zone Message

::::WorkflowBlock
:::WorkflowBlockItem
Create a presentation with content inside of zones. Make sure to toggle on **Interactive** in the top right corner.
:::

:::WorkflowBlockItem
Select the transition event in the leader zone in your presentation. It may be helpful to include “Leader” and “Follower” in the zone names.
:::

:::WorkflowBlockItem
Add a transition event to the content you want to display first, then drag that event to the other content in the presentation.
:::

:::WorkflowBlockItem
In **Event Properties > Advanced**, select **Add Command.**
:::

:::WorkflowBlockItem
Select the **Link** command and the **Synchronize** command parameter.

:::

:::WorkflowBlockItem
Toggle the down arrow to enter a **Keyword**. This will be used to trigger follower players to display content.
:::

:::WorkflowBlockItem
**Save** the presentation.

## Creating the Follower Zone Event Listener

::::WorkflowBlock
:::WorkflowBlockItem
Select the follower presentation zone.
:::

:::WorkflowBlockItem
Add a **Synchronize** event to the content you want to display first, then drag that event to the other content in the presentation.

:::

:::WorkflowBlockItem
In the **Event Properties** pane, under **Specify synchronization keyword**, enter the **Keyword** you selected in step 5, above. When the follower presentation zone receives this keyword from the leader zone, it will start to play.
:::

:::WorkflowBlockItem
Do this for all of the follower zones in the presentation then select **Save**. You can also select **Save as** to save the presentation with a different name for additional players (for example “Player 3 follower presentation”).
:::

:::WorkflowBlockItem
If you are publishing from a single player with multiple outputs (the XC4055, XC2055, or XT2145), the presentation clock does not need to be synchronized and you can now select **Publish** to publish the synced presentation. In all other cases, you must use the following section to synchronize the clocks of the players that will display your presentation.
:::
::::

:::hint{type="info"}
To synchronize between zones on the same player, use the **Link** command with the **Zone** command parameter.
:::

# Sync Player Clocks

In older versions of BrightSignOS and BrightSign Author, you must synchronize player clocks, and leader and follower players must be defined. To do this:

::::WorkflowBlock
:::WorkflowBlockItem
Select the transition event leading to the **Video State** in the leader zone.
:::

:::WorkflowBlockItem
In **Presentation Settings > Interactive > Synchronization** (under the **Networking** tab), select **Enable enhanced synchronization** and choose **Master**.
:::

:::WorkflowBlockItem
Select a transition event leading to the Video State in a follower zone in your presentation.
:::

:::WorkflowBlockItem
In **Presentation Settings > Interactive > Synchronization**, select **Enable enhanced synchronization** and choose **Slave**.

:::

:::WorkflowBlockItem
Do this for all the follower zones in your presentation, then **Save** and **Publish**. You can also select **Save as** and **Publish** the presentation with a different name for additional players (for example “Player 3 follower presentation”).
