Bluebell Goes
Small With Two
New Products

A

t IBC 2015, Bluebell Opticom will
introduce two new products that
provide long-distance control and
video transport for the smaller "box"
cameras that have become popular for
POV applications.
It has been our goal from the
beginning to provide a solution with
the lowest possible cost, while still
being SMPTE-compliant for the video
(that is, passing pathological signals).
Development of the new TDM-750
was driven by a number of projects
in which the customer or system
integrator planned to use cameras
like the Panasonic AW-HE120 for
applications such as concert halls,
meeting rooms, large AV installations,
and reality TV/"fly on the wall"
programmes. The TDM-750 fits
nicely alongside our TDM-700, which
provides the same functionality but
adds genlock, tally, and RS serial
camera control.
An affordable, modular interface
based on Bluebell's popular and
growing BC Series transport system,
the TDM750 uses multicore fibre that
allows the installer to transport and
control a large number of remote
cameras over a single cable. The
interface requires only two fibres (with
an option for single-fibre operation),
making it perfect for smaller robotic/
POV camera systems that require only
a single video path and bidirectional
data via Ethernet. It is available as a
stand-alone link or in a 19-inch rack,
from which it can connect multiple
cameras from single or multiple
locations. The self-contained module
can also be used as a building block
in larger optical networks, alongside
other interface requirements.
The new BN385 is targeted towards
higher-end cameras such as Grass
Valley's LDX 80. These cameras

are currently installed in the main
Parliament/Senate
chambers
in London for HD coverage of
proceedings.
In a typical setup, users would assign
one of the SDI paths for PGM video,
the other for a feed with viewfinder
overlay/menus, and the Ethernet ports
for camera control and pan-tilt-zoom
operation.
The
lightweight,
ruggedised
aluminium enclosure can be fixed
directly to the camera mounting
bracket in any environment and, like
the TDM700, can be used with a BC
Series rack at the equipment room/
truck end of the link.
The unit features two 3G-SDI paths
from the camera position with an
optional genlock return, plus a dualport GigE link on just two single-mode
fibres (with optional single-fibre
operation). An IEC mains input (100250 VAC) with a local DC output is
designed to power the camera and
minimise cabling at the remote
position.
Smaller camera systems have
created a spike in demand
for fibre systems that can
support them over long
distances. We will build
upon these products in
the future to create a full line
of solutions that can meet the
requirements and price points of any
operating scenario.
