   7 key parts, one program, and your phone

How the parts connect

CourtCall AI, wired up

Every part, what links it to the brain, and how the data reaches your phone. A solid line is a cable; a dashed line is a radio link.

The program

What controls CourtCall AI

mqtt.on('local/cc/btn/+', async (msg, topic) => {
  const court = courtOf(topic);
  if (state[court] !== 'armed') return showAddReplay(court);
  state[court] = 'replaying';
  const now = Date.now();
  const files = await Promise.all(court.cameras.map(cam =>
    clipper.save(cam, now - 30000, now + 2000)));   // ffmpeg stream copy
  ws.send(court, { type: 'replay', urls: files });  // court screen plays both
  mqtt.publish(`iemi/${site}/${hub}/courtcall/clip`,
               clipEvent(court, files), { qos: 1 });
  setTimeout(() => (state[court] = 'armed'), 40000);
});
