The audience display renders the overlays on a green background (or a color of your choosing). You would then need to connect the output of this to a video mixer capable of chroma keying, to superimpose it on your video. You can use a hardware or software video mixer (such as Open Broadaster) for this.

We used one computer to run Cheesy Arena, and then one for each additional display (audience, FTA, announcer, red scoring, blue scoring, referee, red alliance stations, blue alliance stations). This page describes our networking setup, but most events can get away with a lot less.

We built some custom hardware (an embedded microcontroller board plus an LED driver board) into a project box and put one at each end of the field. We'll post the specifications for that on GitHub once the guys who worked on it finish documenting it. The communication was UDP over Ethernet -- just a plain 32-byte packet containing RGB and transition time values for each of eight channels.
