In pro football who comprises the booth?

Question

I know when there is a booth challenge the team's don't use one of theirs. But who is in the booth?

Answer 1

In pro football the challenge is performed by a field official through a little screen on the sidelines, and he is assisted by replay officials in the booth, but the field officials or the coaches initiate a challenge. In college, there is an actual member of the officiating crew in the booth who can stop the game on his own for a challenge.

Answer 2

A play-by-play color commentator and an annalist or two
