DVG recently completed the install of a 4K UHD 12G router for the U.S. Library of Congress. The project consisted of a Ross Video Limited Ultrix Router populated 132×136 with redundant controllers and power supplies controlled by seven RCP-QE36 remote panels located across the facility. The system includes a redundant master reference and time code generator system with two Ross SRG-4500 generators and one ACO-4500 changeover switch. DVG also provided two Hitachi DK-H200 HD cameras with Fujinon HAS18x7BDM lenses to be used in conjunction with Ross Cambot 520PT pan/tilt heads and Ross Smartshell Robotics control system. Transmission from controller to head and camera via Multidyne fiber optic transmitters and receivers.
