A new version of Studio Technologies’ Live-Link remote camera interface system is now available for 4K applications. The 07X-series is especially suited for live sports and event productions. The camera end unit features four 3G-SDI-compatible inputs to accommodate data-intensive 4K digital video streams and an additional 3G/HD/SD-SDI input for an alternate digital video stream. The camera end unit also includes a 3G/HD/SD-SDI return from the control room unit for confidence monitoring. All signals are transported using just two strands of single-mode fibre, one each for signals in each direction. “In response to customer requests, we built on our existing Live-Link systems and added four time-aligned 3G-SDI inputs to handle the four-quadrant 4K video signal,” says Gordon Kapes, president of Studio Technologies. “The new 4K-compatible Live-Link system is camera agnostic and is directly compatible with several manufacturer’s products.” The Live-Link 07X-series is designed to make 4K camera location deployment quick and easy. It is a complete solution for transporting 4K and monitor video, on-air audio, intercom and IFB communications, and data between the camera position in the field and a production vehicle or studio. Operating over two strands of single-mode fibre-optic cable makes interconnecting the units very simple. The camera side offers four analogue mic/line sends (camera to control room) with selectable gain and 48 V phantom power, along with two analogue audio returns (control room to camera). Live-Link 07X also incorporates a two-channel IFB output (camera side) and two four-wire interfaces (on the control room unit) that transitions to a two-channel party-line (PL) intercom circuit on the camera end. The PL “comms” system features an auto nulling function that leads to great audio quality. Both the party-line intercom and IFB outputs provide DC power to support industry-standard user devices. In addition, the system includes 10/100 Ethernet, RS-232, RS-422 data transport as well as support for GPI/GPO control signals. Users can deploy a Live-Link system in essentially the time required to run two-strands of single-mode fibre-optic cable between the camera location and the truck or studio location. Fibre runs up to 10km can easily be supported. Power for the Live-Link units can be provided by mains-powered 12 volt DC supplies or using broadcast-standard rechargeable batteries.www.studio-tech.com
