The new technology happens to be a fleet of Microsoft Surface Pro 2 tablets, modified for the job. The slates will feature a thick blue case to help them survive a full NFL season, and are the property of the NFL, not the individual teams. Certain restrictions have been put in place regarding the storage of the devices, to prevent cheating (hear that, Bill Belichick?).
Microsoft and the NFL entered into a $400 million deal that made the slate the official sideline computer of the league. Besides the thick blue case, other modifications include the disabling of the camera, limited connectivity to a wireless network that runs inside each stadium, and a waterproof screen. There is only one program that each tablet will run. That program, called the Sideline Viewing System, will allow coaches to view digital game photographs.
The tablets are locked up in temperature controlled carts, before being handed out to each team before kickoff. 13 tablets will be on each sideline during the game, while another dozen will be deployed in the coaches' box. During the course of the upcoming season, we are sure to get some televised shots of the tablets doing their thing on the sideline.
