dimedis and NEC in world’s largest videowall totem

The world’s largest free-standing videowall totem has been constructed in Messe Düsseldorf’s north entrance hall. With a height of almost 7m, the installation is a true attention-grabber – and replaces printed posters that used to hang in that position.

The design and construction of the videowall, which consists of 24 NEC 46in screens, was carried out by contractor InoNet Computer. The structural integrity of the wall presented quite a challenge; at a height of 6.80m, the stability of the construction had to be absolutely guaranteed. Proper ventilation also came under careful consideration to keep the screens from overheating under constant operation.

Driving the installation is a single InoNet Magnius videowall controller, which is capable of daisy-chaining up to 144 screens. dimedis’ kompas software provides the content, controlling everything that can be seen on the screens, such as a site map, Twitter wall, videos and news. Since kompas uses HTML5 to display the content, the videowall can be consdered to be one of the largest browser windows in the world. It was put into operation on April 7 2014, and will be used for all trade fairs at Messe Düsseldorf.

Bernhard Wagner, marketing director at Messe Düsseldorf, commented: “We are very proud to be setting a record with our videowall. The aim of the project was to equip the central hub of Messe Düsseldorf with a way to offer visitors orientation and information. The videowall is a much better means to this end than the printed poster walls we used before. Now, we can display dynamic images and up-to-date content such as news and Twitter feeds. We’re using the kompas software by dimedis, a solution that has worked for us before. We chose kompas because it makes it easy to schedule and combine static and dynamic content alike using drag and drop.”

Patrick Schröder, division manager digital signage at dimedis, said: “Aside from its sheer size and the large number of screens, the wall challenged us to find a simple, reliable and appealing way to manage and present content for such a huge set-up. kompas displays all of its content using a browser, so we’re quite proud to be running one of the world’s largest browser windows! The technical challenges we overcame for this project prove that kompas is the ideal tool to manage multimedia content. With this videowall, our customer Messe Düsseldorf makes an impressive example of how digital signage can work as the central communication tool for trade fairs and events.”
