In a nutshell, users upload, create and schedule digital signage campaigns based on their desired message using the CommandCenterHD interface through their web browser. Once the campaign has been scheduled and saved, the MediaBridge talks to the digital media player and tells it what media needs to be displayed when it needs to be displayed, and for how long. The media players periodically check in with the MediaBridge to make sure they have all the latest campaigns and media for display.
