In outside broadcast trucks, operators at individual
positions can connect to all available PCs and servers, so
devices can be accessed and controlled anywhere, leading
to total fl exibility within the vehicle.
In studios and control rooms, computer images and
multiviewer outputs can be transmitted to video screens
and videowalls as needed and changed around instantly.
This saves cost and creates exciting new opportunities for
on-set displays as well as bringing a new level of fl exibility
to the overall distribution of computer-format (DVI, HDMI,
DisplayPort) video data.
What examples are there of KVM switches in action?
At BT Sport in London, which is probably the largest, most
recent broadcast system integration, two interconnected
288-port Draco tera KVM switches connect editors,
designers and production staff to banks of Avid editing
machines, Omneon storage devices, EVS servers, Chryon
production tools and the host of other essential broadcast
components. They provide the required delay-free
switching between sources and workstations to create an
end-to-end tapeless workfl ow; offering immediate access
to incoming feeds and stored content throughout 20 edit
suites or on any of the 200 producer desktops.
The ARD group in Germany has standardised its radio
studio operation throughout several major broadcast
stations within the group, including HR and NDR, on IHSE
KVM switches. Presenter and producer workstations
in general purpose studios can be quickly reconfi gured
to access the computer systems necessary for the
programme being aired. These include dira! On-air playout,
AVT touchscreen-based telephone management system,
traffi c and news computers, jingle and sound byte players
and workfl ow management.
One of Hollywood’s most prestigious post production
facilities, Sonic Magic Studios, uses a Draco tera KVM
switch to manage over 250 TBytes of storage with instant
switching to several sound stages and edit suites, allowing
editors to use any studio with the equipment they need.
Videohouse’s newest outside broadcast van, OB14, has
an onboard 32-port Draco tera compact switch to allow
each operator position access to any of the system control
servers, character generators, rasterisers, EVS servers and
SloMo devices by hotkey selection, whenever they need it,
with zero latency and no switching delay.
Images on a 36-screen, on-set, video wall in the news
broadcast studio at Pink, in Belgrade, are selected and
transmitted from a16-output mutliviewer system by an 80-
port Draco tera compact KVM switch, enabling producers
to select the images to be shown on the screens to suit
the news story being related. The images are also made
available for display on to 10 x 55” and 16 x 46” videowalls
in the News Control and MCR rooms.
At the ZDF studios in Mayence, Germany, live broadcast
servers and editing equipment are accessed and controlled
through a 288 port KVM matrix switch, enabling live
program viewing and monitoring on single and dual-screen
displays. What sets IHSE apart?
Our philosophy is to create products that perform their
tasks reliably and incorporate functionality that is required
by users within each specifi c industry; features that are
essential in all applications, none more so that broadcast.
The key is reliability – the matrix itself is a device that needs
to work continuously, without failure or interruption. And
if any problems occur, it must react automatically and
not interrupt the broadcast operations it supports. So
we pay particular attention to the quality of build and
features that ensure 24/7 operation: for example, should
the main controlling processor fail, the switch will maintain
operation with the current confi guration. The normal levels
of dual and triple redundancy of components found in
the broadcast industry, combined with redundant routes
for critical connections using Linkloss auto detection
and switching, provide safety and security that ensure
broadcast studios are not taken off-air because of system
failure. Flexibility is highly important. The ability to easily add
to a system or reconfi gure it is essential and one that is
achieved through Flexport: a method that allows each port
to be dynamically confi gured as an input or an output.
We develop our products through interaction with users
and there are many examples, particularly in the broadcast
sector, where features have been added after user request
that are now considered invaluable.
What are your expectations for IBC2014?
Judging by the previous shows, it is likely to be bigger and
better. We expect that more broadcast professionals will
stop at the stand and investigate the opportunities that
KVM offers to them, and the ways that it can be used
to streamline their operations and assist them in running
today’s modern broadcast studios and editing facilities.
