Matrix Routing Switchers Evolve In Digital And Analog Worlds Despite Economic Slump

Matrix routing switchers are often
the brain trust for an entire corporate
AV system, directing sources where
to go and generally keeping everything
in order. Now these products
have blossomed into something bigger
and better, boasting more inputs
and transmission formats than ever
before. However, with the recent
economic slowdown, their sales
have suffered considerably, causing
integrators to adjust to the change in
business as the corporate world waits
for the impending fiscal upswing.
Matrix routing switchers have
grown in size since they came into
the market many years ago. As companies
grew in size, so did their need
for more inputs and outputs. As Glen
Swanson, account manager for FSR
explained, this trend in size seemed
to never end. “Prior to the slowdown,
the trend has been to create and install
bigger matrixes. Matrix switching in
the corporate environment has been
consolidated to central point, giving
them more flexibility, meaning anything
they want, from any source,
in any direction. So sizes continued
to grow larger and larger. With this
economic slowdown we’ve been dealing
with the last two years, that’s
all stopped. Matrix sales in general
are way down across the board. It’s
been a holding pattern for the last 18
months or so.”

Despite the global recession,
matrix-switching technology has
continued to develop, particularly
through mixing of analog and digital
formats. RGB Spectrum primarily
works with digital matrix switchers, creating “cross-format” switchers that
accept and convert analog signals into
DVI for routing to high-resolution
displays. While demand for analog
switchers currently continues, RGB
product marketing manager JX Loeb
sees that shifting. “There’s a strong
trend to digital, though some people
are still buying analog switchers. We
see that changing because as more
sources become HDMI, and there are
copy protection issues with HDCP.
With the migration to digital signals,
there is also an increase in copy
protection challenges, such as how
many displays can you can route to
with an individual source.”
Even with more signals becoming
HDMI, some companies, like Atlona
Technologies have retained their interest
in analog switchers that work with
Cat-5 or Cat-6. PR director for Atlona,
Joshua Carlson, noted, “Essentially
we’ve realized HDMI has its limit,
so for much of our Professional line
of matrix switchers, we use Cat-5
or Cat-6 so they can extend up to
200 feet without signal degradation.
Cat-5 is much cheaper than HDMI
anyways. We also have repeater units
placed in each of those models to allow it to extend another 200 feet.
We’ve tried to make these products
more economical and convenient for
installers. Another big thing with our
Professional line is that they’re cardbased
systems, so if you wanted to
change formats, this makes it easy to
change from Cat-5 to HDMI.”
Working with integrators to make
margins is an important goal for
most matrix switcher manufacturers.
FSR’s Swanson mentioned the significance
of choosing the right switcher
by discerning its capabilities. “The
big thing when choosing a matrix
switcher is selecting it by the breadth
of features and specifications. A lot of
people choose by just bandwidth, and
they don’t care how it’s achieved. The
result is that the image quality suffers
dramatically, and then they end up
with more service calls. Integrators
can help themselves by paying attention
to achieving flatness throughout
the entire frequency range and by
making sure the switcher isn’t causing
artifacts or image disruption
when optimizing these switchers in a
system.”

RGB has installed a web-friendly
control panel (WCP) in its switchers,
among other innovations that
allow for easier installation, giving
contractors the ability to focus on
other aspects of a project. “By finding
a switcher that has the right tools
to make the installation go easier,
a contractor will make better margins,”
Loeb said. “We’re constantly
adding diagnostics to our command
set and WCP. We also have indicator
lights on the back panels of our
switchers that show if a card isn’t
communicating with the back plane,
or if the card isn’t seeing an input.
Immediately you can start tracing
the problem upstream to your source.
They’re sort of a fast way to see that
the signal isn’t getting to the switch.
They also offer extensive EDID management.
We paid a lot of attention
to help streamline trouble shooting.”
As switchers become smarter and
less problematic during installs, the
technology overall continues to evolve.
“The future is a completely Cat-5-
based solution for large scale video
routing using the new format HDBaseT,
provided that it can easily convert
back into HDMI or DVI based formats
commonly used in commercial installations,”
Carlson noted. “This is only logical, when you consider the scope
and need for constant expansion that
is prevalent in the commercial world,
especially with digital signage, a format
with the capabilities of HDMI but
without the distance limitations. This
would be greatly beneficial to both
installers and their clients, not to mention
cost-savings of using Cat-5 for all
cabling.”
