Compositor

The Compositor Server is a 3U workstation running windows that runs OBS. This computer will take in all the video feeds on the field and produce a single feed that gets sent to the Ultra Encode and to the Pits. The underlying technology is NDI for Pit distribution, if not a private feed on YouTube if the network cannot reach that far.

OBS

Open Broadcast Software or OBS is the underlying software that runs the video feeds. it will take in all the Camera feeds based on the RTSP feed produced in the camera. Additionally this will also layout the camera feeds similar to an actual competition
