Telemetrics camera system delivers HDTV broadcast

KGW NewsChannel 8 in Portland, Oregon recently completed an upgrade to HDTV in its news production department. Included in the over 500 new products installed was a Telemetrics Camera Control Robotics System, which provides unified camera robotic control capability on a single platform for both the indoor and outdoor camera systems.

"There were several choices available for different cameras, lenses and other gear but Telemetrics was the only vendor who could deliver a single system for unified control of the new indoor HDTV cameras and the mix of outdoor HDTV digital and analog cameras," said Eric Dausman, director of technology, KGW NewsChannel 8. "It's obvious that Telemetrics really understands the needs of the marketplace and has the experience to address these kinds of complexities."

As explained by Dausman, one aspect of the redesigned KGW newsroom is a complete HD environment consisting of two indoor and two outdoor systems to control four Sony HD cameras and Fujinon remote control lenses.

The Telemetrics CLIU-HFUX 310 Camera Control Interface unit, with dual camera support, provides the interface between the Telemetrics Control Panel and software and the Sony camera fiber interface unit. This configuration allows for camera paint and lens control as well as robotic control of the Telemetrics pan/tilt heads and other robotic devices such as Telemetrics' Camera Trolley System or Televator Elevating Pedestal. All robotic control signals are sent through the Sony fiber interface. This allows for the remote camera and Telemetrics robotics to be run via fiber optics over very long distances.

A rooftop HD camera was installed in a weatherproof Telemetrics LWP-HOUL Heavy Duty Large Camera Housing, fitted to a Telemetrics PT-LWP-S3 Servo Pan/Tilt Head. The second outdoor HD camera, referred to as the Rose City Sky-Cam, is similarly outfitted and both locations transmit video and receive control signals over fiber thanks to the Telemetrics CLIU-HFUX 310 Camera Control Interface. In the future, KGW plans to move its entire Sky-Cam network of 10 cameras to Telemetrics control.

"Our outdoor scenic cameras have been in use for about 12 years now and are an integral part of our community coverage," adds Dausman. "We plan to control them with a Telemetrics system because of its problem-free, high performance quality. We knew we wanted to use Telemetrics if possible for the new HD outdoor cameras. It really solved our problem when Telemetrics said we could control our new Sony HD cameras with a single system. All of our decisions were confirmed when everything workedright out of the box. The system has proven reliable ever since." In the control room, the Telemetrics desktop CP-R-3A Remote Control Panel, complete with CPS-ST-S Studio Control System Software, operates both the newsroom and the outdoor HD cameras using a dedicated network. The system offers single operator efficient management of studio operations, with such features as storyboard configuration presets and camera grouping. The joystick panel provides trim controls for pan/tilt/zoom and focus, as well as camera iris and master pedestal. This allows the operator to adjust the camera position with smooth, on-air quality precision.
