THE TECHNOLOGY
Electrosonic carried out the detailed design of the AV systems,
working closely with Barclays. Some equipment choices were
determined by Barclays’ policy and/or by compatibility issues,
but in all cases, equipment was selected to be optimal for the
job, and of a kind for which Electrosonic could ensure long term
support.
The architecture of the video wall displays is based on the use
of Crestron DigitalMedia matrix switchers, sited in central racks,
the outputs of which feed Crestron DigitalMedia scalers sited
QH[W WR WKH /&'V 7KLV DUUDQJHPHQW JLYHV FRPSOHWH ƄH[LELOLW\
a simple means of achieving video wall “tiling,” capacity for
expansion or changes, and eliminates any cable length problems.
The central racks also accommodate the main sources, such
as PCs (free issued by Barclays) which provide multiple DVI
outputs, Cabletime Digital Media decoders, Cisco codecs, etc.
LCDs used in the video walls and meeting rooms are from NEC,
and all use LED illumination. The two interactive displays in the
Situation Rooms are equipped with infrared multi-touch overlays
from U-Touch.
The meeting rooms are all equipped with Crestron room
control, a Crestron presentation switcher, Polycom “Sound
Structure” automatic mixing and echo cancellation, and Cisco
video conferencing codecs. The latter include “Speaker Track,” a
facility where a microphone array directs the video camera to the
person who is speaking.

undertaken.
Barclays has every reason to be proud of its new
Global Command Centre, and Electrosonic is
pleased to have been a member of the team which
created it.

data to help operators pinpoint power outages.
The Fresno center features a mixture
of operations and management areas.
Following current trends in collaborative
working, operators work in teams and
have access to data from any other
operator in the center or at any other
PG&E DCC facility. They can also tap into
a diverse array of video sources, ranging
from high resolution graphics to the local
weather channel. The approach requires
real time information to be visually
available to operators in a much larger
format than ever before.
To achieve this enhanced functionality, and
to support 24/7 operation, Electrosonic
installed a number of 3x2 video walls in
the operations areas. These use Mitsubishi

cubes with LED illumination. Each video
