Systems supplied include television head end equipment, remote fiber optic cameras, outdoor high capacity loudspeakers and all electronic equipment.


The broadcast system installed by E-J is used by CBS/USA-TV and all major foreign networks for full coverage of the US Open . The stadium also contains six TV studios, three interview rooms, thirty TV broadcast booths and ten radio broadcast booths. The stadium has full camera coverage with camera platforms. Camera boxes are each equipped with multiple custom-made Triax, Precision Video, Coax, and Audio Cables runback to the teleproduction area. This teleproduction area is linked via a fiber optic network back to a remote satellite up link site.

The site has four show courts with full broadcast capabilities. The show courts also have fixed cameras with a fiber optic link to the TV head end system in the stadium for broadcasters to view on air matches without need for a crew. It is also fed into the internal TV distribution.


The USTA campus contains a dedicated cable TV system.

The audio system also distributes audio signals for broadcasters use. These signals are umpire, scorekeeper, ambient sound, and interview room feeds.
