For the television broadcast of all NFL preseason, regular season and postseason games NFL Broadcasting, on behalf of the League’s network television partners, can require offensive linemen to wear microphones embedded in shoulder pads in order to capture ambient sound from the playing field. The pads will be wired by NFL Filmstrained technicians. Microphones will be opened after the offense breaks the huddle and will be closed a few seconds after the snap of the ball. At no time will the microphones be open when the players are in the locker room, the huddle or the team bench areas and all transmissions will be encrypted. Audio captured in accordance with this provision will be used only in the live ambient audio mix of that particular game. The NFL will require its television partners to agree to use best efforts to refrain from broadcasting any captured audio that contains inappropriate or sensitive content, and that their failure to do so shall result in a loss of the right to broadcast such audio in the future.
