Advanced Control & Monitoring Far
Beyond Keyboard, Video And Mouse
With the proliferation of computer controlled infrastructure, one of the fastest developing
technologies in the broadcast business has been the KVM switch...

VMs started life as hardware
devices allowing multiple
computers to be controlled from
a single keyboard, video monitor
and mouse.
KVM sharing devices function in
reverse, allowing a single computer
to be connected to multiple monitors,
keyboards, and mice. While not
as common, this configuration is
useful when the operator wants to
access a single computer from two
or more locations. Traditional KVMs
allows users to control computer
equipment up to 300 metres away
from the user interface.
They include support for standard
Cat 5 cabling between computers
and users interconnected by the
switch device. In contrast, USB
powered KVM devices are able to
control computer equipment using
a combination of USB, keyboard,
mouse and monitor cables of up
to five metres.
Although virtual KVM switches
have replaced dedicated KVMs
in many networks, development
of new and expanded hardware
devices will become a central
element of the transition to IP-based
digital media distribution systems.
The following is a short summary
of new products in this broadening
category seen at IBC2014.

CCS4-Pro allows users to switch
between disparate systems

Adder Technology produces a
wide range of KVM interfaces. The
AV4PRO-DP allows four computers
e quipp e d with D isplayPor t
technology to be controlled from

a single KVM console. The switch
enables USB HID (low and full
speed) devices to be continuously
emulated to each computer. This
allows instantaneous and reliable
hotkey switching whilst also
supporting the extra keys and
features of enhanced keyboards
and mice. The ADDERLink INFINITY
Dual VNC is a high performance
KVM over IP server that can be
accessed remotely via IP with a
VNC viewer and / or simultaneously
with an AdderLink Infinity receiver.
The company recently expanded
its AdderLink Infinity range with
the AdderLink Infinity 1002 digital
KVM extender, CCS4-Pro switch
and X-DVI Pro DL extender. The
IP-based AdderLink Infinity
1002 has dual ports which allow
redundant network operation and
the opportunity for network teaming.
The AdderLink Infinity 1002 is based
on the 1000 and incorporates all
the same features, such as video
encoding. Enhancements include
an optical port. The new Adder
CCS4-Pro (see Diagram 1) allows
users to switch between disparate
systems. In addition, the CCS4-Pro
features a network port. Users can
easily see which port is in use, in
real-time, and switch remotely if
needed. The presence of the port
also means that firmware upgrades
can be performed quickly. The third
new product, the AdderLink X-DVI
Pro DL, now incorporates full dual
link resolution capability up to
2560 x 1600 pixels. It can transmit
a dual link video stream along with
audio over a single CATx cable,
up to 50 metres
Many of the leading KVM providers
that offer remote accessibility have
based their technology on either
raw Ethernet or TCP/IP, also over
Ethernet. Both of these techniques
have in common their use of Ethernet,
probably chosen because the
hardware components and cables
are cheap and easily available.
Barnfind Technologies as a
transport provider can transport

Ethernet through its BarnOne
matrix which is available with up
to 32 x 32 crosspoints and full
routing capabilities). Barnfind can
provide this using a combination
of optical fibre and RJ45 Ethernet
SFPs, allowing cable termination

HID support. Additionally, matrix
switches free up space in your
data centre. Plus they're cooler and
quieter, eliminating excess noise and
heat in the workplace environment.
Along with dynamically allocated
I/O ports, some matrix switches
enable mixing copper (CATx)
and fibre optic cabling, like

Agility KVM-over-IP system
supports point-to-point
signal extension as well as
sharing, multicasting and
matrix switching, all over
an IP network.
For video-heavy extension
over short distances, you
can incorporate an HDMI,
DVI or SDI repeater using
native cabling, or an
extender kit using proprietary
uncompressed technology.
