Telecast’s Latest Innovations At NAB
By Steve DeFrancesco, Vice President and General Manager, Telecast
The use of fibre optics technology is exploding for audio and video transport, which means increased demand for innovative, costeffective systems that can move large volumes of signals over existing fibre optic infrastructures as well as temporary, ‘throw down’ networks. In particular, fibre optic technologies have revolutionised the world of mobile production and outside broadcasting (OB). Fibre is able to carry signals further and with greater fidelity over a smaller, lighter, and cheaper medium than copper cable, lightening the load on trucks and enabling faster deployment and strike. It’s no wonder that many of today’s leading edge sports and entertainment venues are pre-wired with a built-in fibre infrastructure, which makes the OB task easier. At this year’s 2012 NAB Show, Telecast Fiber Systems will be at the forefront of companies that are demonstrating innovative new solutions for fibre optic signal transport in live production and OB applications. Two examples are the company’s new Cobra™ 2DT, a fibre optic camera interface for Sony’s new digital HD triaxial camera chains, and the TR6442i (CommLink), a fibre optic transceiver system designed to carry two intercom channels over a single strand of fibre spanning distances of more than 40 kilometers.

Telecast - Cobra 2 DT

Going The Distance
Up until now, even the state-ofthe-art in digital HD cameras has relied on analogue transmissions for communications between the camera and its CCU, but Sony has broken new ground by introducing the industry’s first ever digital triaxial systems. These higher quality, lower cost HD camera systems are receiving a tremendous reception by the professional video production community, say Telecast. As the latest addition to Telecast’s patented Cobra line of triax-to-fibre camera extension systems, the Cobra 2DT gives users of Sony’s HXC-100K and HSC-300K cameras powerful, distance-spanning fibre optic connectivity for the link between the camera and its control unit (CCU). The Cobra 2DT takes

the new Sony camera chains a step further by enabling broadcasters to carry the camera-to-CCU link over lightweight, inexpensive fibre, whether it’s a tactical cable or an installed fibre infrastructure in a sports arena or other broadcast venue. Targeted to university and OB sports productions, Telecast say the Cobra 2DT transceiver is ideal for situations in which the distance between the camera and its CCU makes copper triax cable unfeasible. One example is camera signals that must be transported from the camera sites at a university sports venue to a master control facility across the campus. Like the other members of the Cobra family, the Cobra 2DT converts triaxial camera signals to fibre optics for transport across long distances or in pre-cabled facilities. The Cobra 2DT provides all two-way camera/ control signals for Sony HXC-100K and HSC-300K camera chains, including component programme video; return video and genlock; audio, intercom and IFB; and camera control data and tally. The Cobra 2DT is available in a compact, robust, and weather resistant mussel shell-style enclosure. The Cobra 2DT base unit is powered from the camera chain’s CCU, while the Cobra 2DT camera unit is powered by a 100240 VAC power adapter. Two of the base units can be configured into a single 1RU rack mountable enclosure. The system supports ST-type connectors, OpticalCON connectors, or MX connectors to

ensure robust and trouble-free links. Bridging The Gap The TR6442i (CommLink) caters for OB applications, such as television sports and special events programming, A/V installations, such as theme park and theatre installations, corporate events and industrial testing environments, that require the ability to transport intercom signals over long distances. In many of these types of installations, producers are looking for fibre solutions that support equipment, such as cameras, microphones, and intercom systems, which are already in place in the operation. Telecast designed the CommLink to fill the gap between the use of short-range copper cables and the company’s high-end Adder II™ audio system. Based on several years of research and feedback from SNG, OB, and studio operations around the world, the CommLink is ideal for any operation that requires the rapid deployment

of communications systems over long distances. The CommLink uses a single strand of fibre to carry two channels of ‘production intercom,’ ensuring robust voice and data connectivity over distances far beyond the capacity of copper cables. Compatible with the industry’s most popular party line, digital matrix, and generic four-wire/data intercom systems, the CommLink features the industry’s most advanced auto-nulling hybrid technology. When in two-wire mode, the CommLink will extend two channels of a Clear-Com® party-line system or a RTS™ twowire intercom system. When no intercom power supply is available, the CommLink transceiver can act as a power supply for up to five intercom belt packs. In four-wire mode, the system creates a fibre optic connection from a matrix frame to two remote matrix stations, using either ClearCom Matrix Plus or RTS ADAM (Advanced Digital Audio Matrix), Cronus, or Zeus systems. All remote matrix stations are fully functional, with illuminated alphanumeric displays and call signaling. Alternately, the CommLink system’s auto-nulling hybrid permits the easy interconnection of twowire intercom to four-wire systems, featuring the fastest, easiest setup of any two-to-four-wire hybrid in the industry. In addition, each end of the system can act as a stand-alone two-wire-to-four-wire interface, permitting connection of a four-wire intercom matrix to a twowire intercom system or a series of stand-alone belt packs. ■
