'Higher, Faster, Further'
With Guntermann & Drunck
At ISE 2016, see KVM systems that meet the highest demands in terms of video quality
and ease of use, says Guntermann & Drunck Marketing Director Jochen Bauer...

H

igher - Faster - Further are
general
superlative
forms,
whose origin is sports, and which
often describe the typical aims of
today's society. In the AV industry,
we are dealing frequently with a
further superlative - 'more'. As in
more functionality, more interactivity
and more connectivity, and in recent
years the constant more of ever more
resolution.
For a few years now everything
has revolved around the 4K theme -
the currently accepted superlative.
Fraught with initial transmission
challenges, as is often the case, this is
now under control, and thus even the
most complex content today allows
display at a vast distance from its
source.
Particular challenges arise however,
where requirements include remote
operation of such sources in addition
to pure AV transmission. Because
as long as sound and image arrive
synchronously at the workstation
(keyword lip sync), latencies during
transmission are to a limited extent
entirely permissible, as they are simply
not perceived by the user.
The situation changes if another
component is added - the return
channel. Latency parameters are far
more tightly limited when ensuring
an optimal user experience. A delay
of >100 ms can result in, for example,
a visible mouse movement, and from
delays of >250 ms between input
and feedback (via the video signal), a
system is considered no longer fluently
operable. These are values which
KVM manufacturers have to consider
in depth - because, unlike pure AV

G&D CrossDisplay switching scenario recall

transmission, only a delay-free system
enables a good user experience.
Thus G&D has focused on optimum
operability of its systems for
decades. And this starts with video
performance.
Compressed Or Uncompressed
When
considering
video
performance, the initial question
arises regarding compressed or
uncompressed
transmission.
Of
course, the best case scenario is
transparent transmission, in which the
image data remains totally unaffected.
In many places however, external
circumstances give rise to the need for
compression, in particular bandwidth
limitations.
Thus uncompressed video signals
of 4K and upwards at full frame rate
require transmission via fibre optic
cable, in order to ensure sufficient
available bandwidth. In contrast,
classic CAT cabling offers cost
advantages - however due to their
substantially lower bandwidth, also
require corresponding compression.
G&D rely on their own compression
algorithm, to keep development of
this core aspect within their control. In
this way, the manufacturer can quickly
adjust the transmission standards to
changing requirements, and existing
systems can be expanded to include
new signals. Thus this compression
achieves transmission of high quality
video data - and, crucially - the return
channel to the source operation
remains free of latency.
Ultimately there it is no generally
applicable answer to the question,
whether an installation should be
built on compressed or transparent
systems - as this is far too dependent
on the application and the given
infrastructure in individual cases, and
not least, on the installation budget.
For this reason, G&D offers not only
KVM extenders for transparent video
transmission of up to 4K at 60Hz,
such as the DL-Vision, but also highperformance systems that use their
in-house HDIP compression method in

its most recent development
stage, level 3.
G&D also offers KVM
extenders such as the DLVision,
which
transmits
uncompressed
resolutions
of up to 4K at 60Hz via fibre
- completely transparent
and lossless, pixel by pixel,
with no latency, up to 10
kilometres.

G&D DL-Vision offers uncompressed 4K at 60fps

Intuitive Operation
But high-performance hardware and
good video performance with latencyfree operation are only the start of
a good KVM system. Installations
frequently grow into powerful control
tools and, as such, require a suitable
range of functionality so that the
system can be operated as simple as
possible.
Thus for some time now we have
seen systems, which can be switched
by using the mouse pointer - a range
of sources delivers their content to a
workstation with multiple monitors.
This setup can be operated with
only a single keyboard and mouse
combination.
The user does not have to worry
about the background infrastructure -
but can instead keep track of his tasks
and work intuitively, as with a virtual
desktop.
G&D has now perfected this
functionality. Right from the start, the
CrossDisplay switching was not limited
in the number of integrated screens,
and so now also computers with multihead graphics are supported. Thus,
an unlimited mix of scenarios can be
switched from all sources and the user
always operates in the visible area and
never 'flies blind'. The configuration
is easily adapted to the screen
arrangement. Also in combination with
a multiviewer, the flexible CrossDisplay
switching can significantly simplify the
application.
Switching States
To quickly call recurring switching
states in such installations, G&D now

offers scenario switching. In control
room applications in particular,
where you can access a wide range of
computers, this makes it significantly
easier to operate the system. Thus
switching
states
for
computer
constellations for specific tasks can be
easily stored.
This allows you to simultaneously
switch sources for multiple consoles
with a single command. Ideal when
an entire control room, for example,
needs to be changed from day to night
shift, or when a very specific computer
scenario is required for fast task
changes.
External Control
In addition to the integrated features
for the most intuitive operation
possible, G&D systems also offer the
option of external control. These
can for example be operated via a
graphically designed touch panel, or
even integrated into the overall design
of a media control.
Here the applications are virtually
limitless, and you can create unique
designs, in which the installation
once again does its job entirely in the
background. The user retains just two
aspects - full control - but without
having to manage the infrastructure
in detail; and full concentration on the
application process itself!
The CrossDisplay switching from
G&D doesn't stop at unusual monitor
configurations and multihead graphics
cards. This means that the user can
work intuitively, as the switching
process simply follows the mouse
pointer. For even greater control, the
systems can also be operated easily via
a graphically designed touch panel.
