Addressing
the television production industry’s increasing demand for a reliable

wireless
HD link, Canon

U.S.A.,
Inc’s. Canobeam DT-150 HD transceiver provides bi-directional,
uncompressed 1.5 Gbps transmission of embedded digital video, audio and
camera-control signals on a single HD-SDI or SD-SDI stream with no delay. Based on Free Space Optics technology, the

Canobeam
DT-150 HD transceiver uses line-of-sight infrared light, sets up quickly, and
requires no RF licensing or coordination, providing wireless HD capability in
situations where fiber or microwave can’t be used.

Telecast Fiber Systems, Inc.,
specialists in fiber optics for television broadcast production, has further
enhanced HD production by designing its SHED (

SMPTE Hybrid Elimination Device)
adapter to interface with the

Canobeam DT-150 HD transceiver.

Using SHED adapters,
broadcasters can connect to the

Canobeam DT-150 HD transceiver
using compact and lightweight single-mode optical-fiber cables
instead of bulky hybrid wire/fiber cables. B

enefits and applications of
these shared technologies will be highlighted at NAB2007, the annual convention
of the National Association of Broadcasters, held April 14-19 in

Las Vegas (Canon booth
#SU 3020).

Another
Telecast Fiber Systems product, the HDX unit, is designed to power television
cameras through as much as 500m of hybrid cable.

A combination SHED/HDX solution consists of
two adapters, which convert signals from hybrid copper/fiber cables to signals
suitable for standard all-fiber cables and connectors.

The SHED/HDX solution allows a camera and base
station to communicate on two ordinary, inexpensive single-mode fibers, and
they also provide the appropriate power delivery option for the camera.

The
single-mode fiber connection between the Canobeam DT-150 HD transceiver and the
SHED/HDX system is made possible due to Canobeam’s Small Form Pluggable (SFP)
module system.

Use of an SFP HD module
allows the Canobeam DT-150 transceiver to interface via single-mode fiber LC
connectors.

“The
combination of

Telecast Fiber Systems’ SHED

adapter with the

Canobeam
DT-150 HD transceiver is an important enhancement for the television production
industry,” stated Gordon Tubbs, director, Broadcast and
Communications division, Canon

U.S.A.

“Together, they provide users with a
seamless, affordable, wireless, point-to-point uncompressed
digital-transmission solution that will play a major role in revolutionizing
the broadcast industry as the transition to HDTV accelerates.

We have a great working relationship with

Telecast
Fiber Systems.

The simplicity of how
their products interface with ours helped make it possible for us to introduce
the Canobeam DT-150 HD transceiver into multiple applications.”

The

Canobeam DT-150 HD transceiver is
the newest member of Canon’s acclaimed series of point-to-point Free Space
Optics transceivers that use infrared light to bridge gaps in high-bandwidth
transmission situations.

The Canobeam
DT-150 HD can relay embedded HD-SDI and SD-SDI video from multiple cameras or
other HD/SD video sources, along with embedded return video and audio to the
camera operator, camera-control signals, and

robotic camera-control data.

The
Canobeam DT-150 HD has an approximate range of up to one kilometer and – like
all Canobeam DT-100 series products – features Canon’s exclusive Auto Tracking
feature to help maintain beam alignment despite vibration due to wind, rain or
unsteady camera platforms.

For
connections to an HD camera, a

SHED/HDX unit
interfaces with the camera side, and then passes the signal via single-mode
fiber to a Canobeam DT-150 HD transceiver.

Signals received by a second Canobeam

DT-150
HD transceiver are output to single-mode fiber and fed to a
SHED

™ adapter for conversion back to
SMPTE hybrid cable in the remote truck or production-control facility.

The combination of a set of Canobeam

DT-150
HD transceivers and SHED


/ HDX solutions enables the mobile production truck to maintain complete
control over the camera via the camera-control signals that can be embedded in
the bi-directional HD-SDI or SD-SDI stream.

Recent
uses of the Canobeam DT-150 HD transceiver interfaced with Telecast Fiber
Systems’

SHED

adapters and

SHE

/HDX units include relaying HD-SDI video captured in front of a
famous

Hollywood theater for a live award show
telecast.

This HD video was beamed to a
mobile television production truck in a parking lot approximately 1,500 feet
away by a set of Canobeam DT-150 HD transceivers interfaced with

SHED
adapters and

SHED

/HDX units.

This bi-directional
link provided full transmission of HD video and embedded audio back to the
truck and transmission of camera-control signals, return video, tally’s, and
IFB from the truck back to the camera locations.

Pristine-quality HD signals were relayed
without delay or interference via Free Space Optics amid the heavy RF
environment of

Hollywood Boulevard.
