[00:01] going to see is a headset on a coach's head like that with a mic in their face talking with their hand on their waist. What's happening is a coach is allowed to talk to either one offensive or one defensive player as they call plays.
[00:14] >> You got me on that, Matthew. All right, Matthew, let's do this. You got me on >> And their hand is on a little belt pack as they hold down a button and transmit to a speaker directly in that player's helmet. So, yeah, these helmets do have
[00:27] tech built into them. It's kind of hard to see and this is an older helmet design, but there are speakers actually inside of this helmet. So, this is the entire tech package that's got to fit inside of one of these helmets. Pretty
[00:39] them at each ear, so they can hear clearly. This is the receiver, and it's receiving an encrypted signal that only they can hear. And this is the battery, which should last about 6 and 1/2 hours, which is plenty for an entire NFL game.
[00:53] they've ever made this whole tech package. Hopefully the player doesn't notice. Anytime you want to know which player is receiving the transmission from the coach, you'll have to look for this little green sticker on the back of
[01:06] quarterback on offense relaying the call and a lineman on defense. Now, if you really have eagle eyes, then around the 50 yardd line, you'll see a black tech cart which has this box on it. This is the coachto player interface box, and
[01:20] encrypted signal. So when the coach gives that play call, it turns green. less than 15 seconds left on the play clock. So there's someone in the press
[01:36] box with this cut off box with a button on it. So if the coaches are still talking to the players at 15 seconds, they can cut that signal and it turns always a lot of tech going on out there, but now you know exactly what's
[01:49] happening. So next time you watch an NFL broadcast, you'll spot that stuff.
