tpc looks in the SHED

20 July 2006

Telecast Fiber Systems has revealed that tv production center Z_rich (tpc), Switzerland’s largest media production facility, has equipped its HD-1 outside broadcast truck with ten sets of SHED (SMPTE Hybrid Elimination Devices) and HDX adapters for its Sony HDC1500 cameras.

The SHED-HDX units replace the bulky SMPTE hybrid fibre/wire cables the cameras are designed to accept with lightweight, standard single-mode fibre, allowing up to 10 times the range of hybrid cable with only 10% of the weight. The systems were integrated by Telecast dealer WIRA Optics.

“SMPTE 311 hybrid wire/fibre camera cable is falling out of favour with many broadcasters because it is bulky, heavy, prone to damage, and distance-limiting. The trend, however, is heading toward using standard tactical fibre cable that is completely non-metallic, since it is easier to handle, significantly more durable, and compatible with existing venue infrastructures,” commented Joe Commare, Telecast vice president of marketing and international sales. “Swiss First League Football, hockey stadiums, and other sport venues throughout Europe are pre-wired with inexpensive single-mode fibre. By using fibre and our SHED camera adapters, tpc has streamlined its OB operations while maintaining the performance of its state-of-the-art Sony HD cameras.”

Telecast’s SHED solution consists of two small adapters _ one at the camera and another at the base station _ that convert camera signals from hybrid wire/fibre cables to standard all-fibre cables and back again. These adapters allow the camera and base station to communicate on two ordinary single-mode fibres while maintaining a pure optical path so that the highest-quality signals originated by the SMPTE-hybrid cameras remain pristine. The most popular configuration uses an optional HDX unit, which also supplies power to the camera via short (up to 300m) runs of hybrid cable.

In addition to the 10 pairs of SHED and HDX units, the 45-foot HD-1 truck is equipped with a Probel 320×416 router, MVS8000 switcher, Stage Tec NEXUS audio distribution system, and RTS communication system to support its 24 cameras. The truck was unveiled at IBC2005.
