G&D rely on self-developed compression method posted: 27/08/2015
When it comes to KVM, the letter V - short for video - plays the most important role because it is the only component that is visible when transmitting and switching signals. The improvement from analogue to digital image signals constituted a major challenge for KVM: high resolutions require high data volume. However, the bandwidth of cable infrastructures, especially when using CAT cables, is extremely limited. Here, signals cannot be transmitted without being compressed. For the benefit of their customers, G&D rely on their self-developed compression technology.
Why the letter V in KVM is so important
When applying KVM technology, the main focus lies on the most critical component: the video. KVM transmission stands and falls with the video signal because high resolutions and crystal clear images without any loss or latency are extremely important. However, such fascinatingly high resolutions also come with great challenges. Without a doubt, one of these challenges is the high data volume required for 4K resolutions with over 10 Gbit/s, which in turn places enormous demands on the cabling infrastructure.
When it comes to data volume, keyboard and mouse signals play only a minor role although they form two thirds of the term KVM. The transfer of these two signals is very stable and not susceptible to faults. They need only an extremely small bandwidth when transmitting a wide variety of signals.
KVM and compression from one source
Although Guntermann & Drunck have been approached by external development institutions regarding the development of a compression, they decided to develop their own compression algorithms to keep both their independence as well as the speed in their own hands. G&D have always been rejecting the development of external compression since they consider compression to be an important part of their development work. The German manufacturers are aware of their obligations to their customers to deliver the best possible video quality even when dealing with market-related changes in graphics cards and monitors and even though this means having to invest person years of developing time.

Keyword bandwidth
For reasons of cost, the bandwidth of KVM matrix systems must be kept on a low level - even when it comes to high resolutions. Due to the limited bandwidth of CAT transmission, the video signal has to be compressed in order to handle the large data volume while guaranteeing high-quality images. High-resolution video content can be transmitted only when compressed. Therefore, the compression developed by G&D uses a multistage process that supports full sharpness and full colour depth at 24 bits.

Compressed or uncompressed - that's the question
At G&D, customers are not necessarily required to pick only one solution. The German manufacturers offer KVM solutions that compress video signals for transmission and therefore support cost-effective cable infrastructures. But their portfolio also includes extenders covering the full range to transmit video resolutions up to 4K. The DL-Vision system, for example, transmits the full bandwidth via two fibre pairs without using any compression, lossless at 24 bit colour depth even over distances of several kilometres - provided the system uses optical fibres, the more powerful cable medium when it comes to transmitting digital video information.

Ready for the future
KVM adapts itself to ever-changing installations, graphics cards (output signal) or displays (input signal). Without the help of external suppliers, G&D are able to react fast to these changes. Experience has shown that internal development is often faster than the collaboration with third parties. In addition, the future generation of KVM components can profit significantly from the interplay between hard- and software. In such a rounded system, customers benefit from G&D standards such as
- Higher image quality
- On-screen display
- Faster switching through harmonised matrix end devices - even for different video formats at input and output side
- CrossDisplay-Switching to use the mouse to switch between channels
- Positive hand-eye coordination
- Lip sync, which is especially important for the broadcast industry.
In many ways, G&D's compression is the key to current and future KVM products. Being able to rely on a self-developed compression also means the protection of investments for G&D customers: on the one hand for maintaining existing installations, on the other hand with regard to the compatibility of future investments.
