alicia is an autonomous
community of Spain in the
northwest of the country, with a
strong regional identity - more
people in the region speak
Galician, which is closely related
to Portuguese and Castilian, as
Spanish is known locally.
The public broadcaster
Compañía de Radio-Televisión
de Galicia (Radio and Television
Company of Galicia, (CRTVG) plays
a key role in creating and promoting
Galician culture.
Founded in 1985, one of
CRTVG's functions is to 'improve
and standardise the use of [the]
ofﬁ cial language' and generally
promote Galician culture through
Television de Galicia (TVG), which
has two domestic digital terrestrial
channels and two satellite services
for North America and Europe, and
the three stations of Radio Galega.
CRTVG broadcasts from the
San Marcos production centre
in Galicia's capital, Santiago de
Compostela, where it recently
upgraded the intercom system
for TVG. The new Clear-Com
communications installation gives
the broadcaster the opportunity
to embrace a wide variety of
modern intercom technologies to
offer native IP, integrated digital
wireless cellular, MADI interfacing,
voice over IP (VoIP) for the
corporate communications server,
redundant ring topology using
dual ﬁ bre optics and intelligent
management of control devices,
including panels featuring rotary
audio level adjusters.
The system was supplied
by Madrid-based QinMedia
and comprises a Clear-Com
Eclipse-Omega advanced digital

matrix intercom platform and an
Eclipse HX-Delta point-to-point
matrix, which has the capability
to seamlessly integrate digital,
wireless, IP and analogue signals.
The two platforms are connected
using non-blocking ﬁbre, which
ensures there are no internal
bandwidth bottlenecks. The
combined system has a capacity of
near to 550 ports but is contained
in only nine rack units, with over
300 possible interface types.
Through the integration of the
Eclipse's native IP communications
facilities, based on the I.V.Core
(Instant Voice-Core) technology,
and V-Series IP-enabled panels,
users can choose between two
connection modes and alternate
them on the ﬂy, without the need
for additional external interfaces.
Operation of the intercom system
is predominantly through V-Series
rotary keypanels, which allow for
quick and intuitive selection and
control of settings. Among the
parameters that can be selected
and adjusted are input, output,
crosspoint in listening and IFB
(Interruptible Foldback) level.
Access to the intercom can also
be extended beyond the dedicated
Clear-Com hardware panels and
on to PC clients through ClearCom Concert server software
connecting to the Eclipse system.
This can be done in a simple and
economical way and is designed for
jobs that do not need a physical
control panel.
MADI is now an integral part of
broadcast centre installations for
audio distribution and at TVG an
interface is used to connect this
technology to the Eclipse matrix. In
this way 64 bi-directional channels

CRTVG intercom system is predominantly controlled via V-Series rotary keypanels

A Clear-Com Eclipse-Omega advanced digital matrix and an Eclipse HX-Delta
point-to-point matrix form the core of the CRTVG system

can be accommodated on a single
card, pulling together all four-wire
communications between the
matrix intercom and the facility's
digital audio consoles.
Full intercom connectivity for
production staff working on the
studio ﬂoor or elsewhere away from
the control galleries is provided
through FreeSpeak wireless
beltpacks. Approximately 50 of
these are available, running on
an extensive cellular network with
antennas covering all areas of the
broadcast centre.
The whole system is managed
through Clear-Com's new EHX
(Eclipse HX) conﬁguration software,
which is much more powerful than
the earlier ECS program. EHX gives
both administrators and operators
an easy and intuitive means of
conﬁguring the Eclipse HX network,
using an efficient, graphical
system. By using this application
all communication, conferencing,
multiplex, duplex and IFB functions
can be controlled from a single
operator position.
A key element of EHX is its
graphical interface, which ensures
fast, simple and secure operation of
the communications system. This is
seen as being particularly beneﬁcial
to large-scale live broadcasts such
as election coverage, major sports
and news events.
But this extensive Clear-Com
intercom installation also brings
huge beneﬁ ts for TVG's day-today production and transmission
workload. It meets the current
needs of a broadcaster that
produces most of its output at

its San Marcos headquarters,
which houses studios and
post-production suites and is
also the base for four outside
broadcast units.
This programming reaches
nearly four million people in
northwest Spain, covering Galicia
and surrounding areas, plus
northern Portugal as well as more
far flung territories over TVG's
satellite services.
"TVG produces a wide range
of programming, including news,
concerts, game shows, debates,
cultural and children's programmes
and sport, all of which rely on
the production team being
able to communicate with each
other so that everyone knows
what is happening all the time,"
comments Jose Maria Alvarez,
General Manager QinMedia. "The
new Clear-Com system gives our
customer that capability, with the
ﬂexibility of being able to select
what carrier format they use
depending on the type and scale
of programme."
Richard Palmer, Clear-Com's
Regional Sales Manager
adds: "TVG is a major regional
broadcaster in Europe and we are
pleased to be involved in raising
the efﬁciency of its productions
even higher. The demands on
broadcast communications are
only set to grow as time goes on
but because the Eclipse combines
many established and emerging
intercom technologies, TVG is now
well placed to cope with any future
changes in both technology and
broadcasting."
