Over the past week in Las Vegas, the NBA and its network partners ESPN and NBA TV have once again used the NBA Summer League as an “Innovation Lab” to experiment with bleeding-edge production technologies. The NBA and its broadcasters are trying out a variety of camera positions at the Thomas & Mack Center — new applications for SkyCam, C360 360-degree systems, removable locker-room robos, a pan-bar robo slash camera, a Hat Cam — as well as new shot-trajectory-tracking and virtual-signage–replacement technologies.
