KVM extends video and audio signals in radio studio

At the beginning of 2015 the rebuilding of the Sterren.nl radio studio was started, an important part of the new studio was the extension of video and audio signals by KVM extenders.

In collaboration with Intronics, the entire studio is now modernized. The studio is not only technically completely redone, it also has a new decor and has been moved to a new broadcast system. DJs Daniel Dekker and Corné Klijn are hosting different artists and studio audience every Friday between 4pm and 6pm. The show can be followed via livestream on www.sterren.nl, without the need for extra staff. Fans can now see what’s happening in the studio realtime.

The challenge: affordable and future-proof solution

dB mediagroup maintains and operates technical equipment and software in the AV world. Sterren.nl chose dB media group because of good experiences in the past, a competitive quote and a great cooperation with various technical parties.

One of the biggest challenges was using KVM extenders to bridge a distance of about 200 meters, to control dual-head HD video, USB 2.0 and audio. The DJ’s workplace only has one keyboard and one mouse and five displays, fed by four PC’s. The challenge was to find an appropriate solution within a tight budget, which also met current and future requirements. Taking into account a new broadcast system and the distance of 200 meters between the server room and the studio.

Solution: an innovative KVM over IP system to fiber

Based on previous experiences, dB mediagroup knew it had to contact Intronics, as KVM specialist thinking in solutions. Intronics found the Adder Technology’s innovative KVM extension and matrix system to be the perfect solution, taking into account the wishes of Sterren.nl. The AdderLink Infinity offers a wide range of possibilities on an IP infrastructure, including a single- and dual-head computer with USB 2.0 support, a CATx connector and an SFP slot for fiber. A unique feature is the free flow mouse operation. With the supplied Viper driver, the KVM system is even able to configure dual head computers for free flow. This allows users to toggle through mouse control between the computers, simply by sliding it over the displays.

Result: low cost and maintenance with maximum flexibilty

Lex Strijker, Project Manager at dB mediagroup, says: "I can proudly say that the radio studio is ready for the future. Through the integration of an IP solution, we keep installation and maintenance costs low. The signal path through an existing network over IP adds maximum flexibility. Thanks to the free flow mouse operation the user with one keyboard and mouse is able to work on five screens simultaneously. A KVM system for the director was also integrated.
