A control room does nothing on its own. It needs to be connected to a match. You can connect it to a whole competition at once, or to one match.
Before you start
A control room. See Creating a control room.
A match with its teams and details set up.
For a whole competition
Every match in the competition picks up the control room assigned to its theme profile.
Open the competition and go to its Theme Profile.
Under Control Rooms, remove the current one if there is one, and assign the control room you want.
To add streams and overlays for every match at once, see How to add streams and overlays at competition level.
For one match: add an overlay
On the Matches table, open the match's menu and click Add overlay. You can also go to the match's Settings > Streams and Overlays > Add New Overlay. The CREATE OVERLAY window opens.
Under Overlay, enter an Overlay Name, for example Main Feed. If a stream exists, choose it under For Stream.
Under Graphics, choose the Theme Profile. This sets the theme and control room the graphics come from, so pick the one that uses the control room you want.
Under Ads, choose the Ad Type (Brands or No Brands). Ads only show with Brands selected and Enable Ads on. Background, Watermarks and Playout start with default settings, so change them only if you need to.
Click Create.
Change the control room on an existing overlay
In the Matches table, expand the match, open the menu at the far right of the overlay's row and click Configure. In the UPDATE OVERLAY window, go to Graphics and pick a different Theme Profile, then click Update.
Open the Control Room
In the Matches table, expand the match, open the menu at the far right of the overlay's row and click Open Control Room. A new room is empty, ready for you to lay out.
