Daily reports from the New York Stock Exchange are of vital interest to investors around the world. Thousands of miles from Wall Street, NHK (Nippon Hoso Kyokai)/Japan Broadcasting Corporation provides its viewers with live on-the-scene HDTV updates from the Exchange. The network captures these reports using the convenience, reliability, and superb HDTV image quality of the BU-45H remote control robotic HD PTZ (pan-tilt-zoom) camera from Canon U.S.A., Inc., a leader in digital imaging.
“NHK Tokyo has approximately ten control panels and can be switched to control different cameras. The advantages of this control system are that we can control more than two cameras by switching the modems connected to each camera. This is yet another reason why we chose the Canon BU-45H remote-control HD PTZ camera, which we have found to be very reliable.”
Offering exceptional controllability and smooth pan-tilt motion, the BU-45H remote-control HD PTZ camera’s robotic mechanism is capable of extremely smooth pans of 340 degrees and tilts of 80 degrees (30 degrees up, 50 down). The pan-tilt mechanism also allows for simultaneous termination of pre-set pan, tilt, and zoom operations, which allows the BU-45H to perform steady movements on-air. In addition to capturing live HD video of NHK’s reporter at the Exchange, the BU-45H’s PTZ capabilities enable it to move and zoom in almost any direction to shoot activity on the trading ﬂoor or any other part of the room.
“NHK chose the Canon BU-45H remote-control robotic HD PTZ camera because it is compact, attractively designed, smooth-moving, and produces good picture quality,” explained Yamana. “The BU-45H is mounted on a wall at the Exchange, and since it does not require an on-site camera operator, it enables NHK to conserve on both human and technical resources. Depending on the market’s trends, the BU-45H camera may be on-air for only 15 seconds or – if we do a live report – as long as 10 minutes.”
A major user of Canon’s robotic systems, NHK can remotely control its Canon BU-45H robotic HD PTZ camera at the New York Stock Exchange from either its Tokyo headquarters or New York bureau. The live HD-SDI output of the BU-45H – combined with embedded audio – is transmitted from New York to Tokyo via four dedicated HD circuits.
“The BU-45H remote-control HD PTZ camera at the New York Stock Exchange is one of more than 100 HD robotic cameras inside and outside Japan that can be controlled by the Tokyo News Center at NHK,” Yamana noted. “NHK Tokyo has approximately ten control panels and can be switched to control different cameras. The advantages of this control system are that we can control more than two cameras by switching the modems connected to each camera. This is yet another reason why we chose the Canon BU-45H remote-control HD PTZ camera, which we have found to be very reliable.”
The BU-45H remote-control HD PTZ camera combines an advanced Canon three-CCD HD camera with a 20X optical HD zoom lens (4.5 - 90mm), a sophisticated remote-control pan-tilt system, and a protective metal housing. The camera portion of the BU-45H employs three 1/3-inch (1,670,000-pixel) CCDs to originate 1440 (H) x 1080 (V) 16:9 HD video. The lens incorporates an advanced Auto Focus function, and sophisticated Canon Image Stabilizer technology. The Canon BU-45H remote-control robotic HD PTZ camera provides genlock input for broadcast video-system synchronization. Output connections include serial digital HD-SDI with embedded audio for HD recording, and an analog composite NTSC for monitoring.
