Rochester Institute of Technology, located in Rochester, NY, is a comprehensive University, specializing in professional and career-oriented education. Its cooperative education program is a hallmark of an RIT education and students have unmatched opportunities in experiential learning in some of the most sophisticated classroom, laboratory and studio facilities available on any campus.

The University stays in the forefront by continually upgrading facilities and infrastructure and this was evidenced by the recent move to high definition (HD) production in the Education Technology Center. But the upgrade was more than transitioning to HD production. The University went a step further and funded an HD mobile production unit for use by our department to help market and promote the University’s athletic program. In keeping with the University’s career-oriented education philosophy, the HD mobile unit was largely designed and built by students from the University over a time frame of approximately five months, starting last June.

The finished product is a full-production HD mobile studio and the only one of its kind in upstate NY. It’s currently deployed to broadcast the University’s production of SportsZone Live, a cable TV (Time Warner/ESPN) sports show covering RIT’s Division I home hockey game. In the studio, we utilize the Telemetrics Coax Link camera control systems with the HD fiber option.

The broadcast trailer is 24’ long and is outfitted with a full complement of recording decks, switchers, audio boards, monitors and graphics equipment. Each of the five Panasonic AG-HPX500 P2 HD cameras, set up throughout the arena, is connected to the trailer using the Telemetrics Coax Link 55C-CA-HDFL Camera Adapter, with an HD Fiber Link Base Station (HDFL-BS) and five Coax Link 55C-BS Camera Control Units rack mounted in a custom-built tray in the trailer.

The cabling distances from the cameras in the arena back to the mobile unit are a variety of lengths and range from 200 feet at the shortest, to 750 feet at the longest. And because we anticipate that we will be broadcasting away games where cabling distances may be longer next year, cable runs have been designed to go as far as 1500 feet if needed. The HD signal is transmitted across a single-mode fiber-optic cable, which runs with the main coax connection in a single custom cable.

Frequency multiplexing is used to transmit baseband video from the camera, external video to the camera, genlock and power, microphone audio from the camera (when used), interphone to and from the camera and camera control and tally to the camera.

Our equipment supplier, Audio Video Systems of Albany, NY, originally suggested we look at the Telemetrics solution and the more I dove into it, the more I realized it was a good fit for us. Compared to other manufacturers’ products, the Telemetrics Coax Link HD Camera Control System could provide all of the features that we wanted and needed – with no compromises. And, the Telemetrics solution priced out the best for us considering our budget parameters.

It’s a robust product and this too was a consideration in our purchasing decision. Again, because students (experienced and otherwise) are the primary users of the equipment, we did not want to be continually servicing a delicate system. In terms of use, it is relatively intuitive considering it was a custom interface. Also, it was easy to set up and begin using the system because everything came out of the box clearly labeled and identified.

My background is in customer service within the broadcast industry and because of this, I tend to judge and evaluate vendors to a higher standard. By my measurement, Telemetrics offered excellent customer service and went above and beyond to make sure that the University was provided first-class service, along with a first class product solution.
