Telecast Powers Duke Univ. Remote Production System

Duke University has incorporated Telecast Fiber System's fiber optic transmission systems to connect its chapel to the nearby Duke Recording Studio (DRS) and the Office of Information Technology. The connection enables remote production and live broadcast of chapel services over the campus cable system and the local CATV university access channel.

The project uses eight Viper II systems, three of which are TR55221 POV links in the chapel basement that connect to Hitachi HV-D25 robotic cameras to carry video, reference and CCU commands to and from the DRS. One of the chapel-based Viper II's also carries control data for DRS system matrices, control delegation and lockout and power control for the chapel system via bi-directional Creston control data.

Audio signals are mixed in the sanctuary and sent to the DRS over six full-bandwith channels from a fourth Viper II, a TX5060 in the chapel basement. Two other Viper systems provide bi-directional production intercom and an additional stereo path in each direction and mixed program video return, which DRS sends on OIT for cablecasting.

The final Viper II system, a TX/RX5122 that was previously installed, operates on existing multi-mode fiber to link the recording studio to the OIT for connection to outbound and inbound broadcast circuits. The fiber link between the Duke Chapel and the DRS was established via a 24 single-mode fiber bundle.
