At the IBC convention,
Thomson announced that customer shipments of its Grass Valley™
Wireless HD Camera System have begun, providing broadcasters,
OB truck operators, and video production companies unparalleled
flexibility in HD productions for sports, entertainment, and
news.
Thomson will also introduce a new RF module
operating in the 2.025-2.110 GHz frequency range, which is
required by the FCC for use in the US as part of what is commonly
referred to as the 2 GHz relocation, currently scheduled for
completion in September, 2007. The Wireless HD Camera System
will be on display in Hall 1-411 at the Amsterdam RAI.
With its compact design, integrated battery
mount, and bidirectional digital transmission, the HD Wireless
Camera System not only frees users from carrying additional
equipment, it eliminates adverse effects from multi-path reflections
and allows them to pass through doors, make low-angle shots,
and choose the most suitable camera-handling position—all
while providing excellent HD picture quality.
The Grass Valley Wireless HD Camera System
addresses customers' ongoing need for fully upgradeable, future-proof
and multiformat-capable products and systems that are affordable
and flexible in order to maximize their media investment.
The HD Wireless Camera Adapter docks to
all LDK HD camera systems, including the LDK 8000. It supports
720p50/60 and 1080i50/60 acquisition while using an innovative
approach both to compression and transmission. The HD Wireless
Camera System uses a state-of-the-art JPEG 2000 technology
end-to-end signal with an enhanced COFDM physical layer-based
transmission for 4:2:2 10-bit quality.
“The HD Wireless Camera System combines
Thomson’s unrivaled experience in broadcast cameras with
the latest in IT technology,” said Jeff Rosica, Senior
Vice President of Thomson’s Broadcast & Professional
Solutions business unit. “The result is a system that
gives users complete freedom of movement under the most demanding
production conditions.”
The connection between a wireless HD base
station and the wireless system’s omni-directional three-antenna
diversity unit (using MRC technology), uses conventional triax
cable enabling users to locate an antenna up to 600m (1,970
feet) from the base station using 11 mm triax cable. A video
booster is available for long-transmission applications between
camera and receiver antenna.
The HD Wireless Camera System is also fully
compatible with studio production facilities, the C2IP camera
control system, and utilizes the same operational control
panels as other LDK series cameras that use the C2IP system.
