Projections in the World of Computers

The 3-chip DLP M Series digital projection series showcased its capabilities at the Heinz Nixdorf MuseumsForum

The Heinz Nixdorf MuseumsForum in Paderborn is the largest computer museum of the world.

In addition to that it is also a spacious, comfortable and modern convention and conference centre, which becomes even more attractive through the exhibition showing items from the creation of numbers and script around 3000 BC up into the 21st century.

High tech is part of the theme and this is visible through the whole building, same as in the main event hall, the auditorium, with its 386 seats in ascending order. Three screens with a height of five metres each take up the immediate front, of which the centre one has a width of nine metres while the side screens are each five metres wide.

Three projectors are working in parallel here: While the centre screen receives its images from a Christie HD10K-M, two HD6K-Ms project onto the sides. At the centre, the projection distance measures 20 metres, as the projector was placed inside a boot, which is separated from the auditorium by a pane of glass. The two HD6K-Ms are each hanging in the room at a distance of 6.5 metres from the two side screens.

Dipl.-Ing. Reinhardt Hardtke is responsible for media and event technology at the Heinz Nixdorf MuseumsForum and he didn’t have an easy task in a museum that is dedicated to high-end technology when he had to decide on the new equipment needed in the the auditorium. For the projectors, he had numerous criteria that had to be met: It had to be a true HD image projection, a 3 chip DLP® product and since two projectors were to be suspended from the hall's ceiling a mere four metres above the visitor’s heads, the devices also needed to be particularly silent. Furthermore, colour uniformity was a major subject, be it with computer material or when playing video formats. The light output required was also specified in advance: the centre projection was supposed to have 10,000 ANSI lumens for the centre projector and 6,000 ANSI lumen, each, for the to side projectors. Additionally, it was important to Mr. Hardtke to have a control option via TCP/IP and a dual lamp system as back-up solution, just in case.

Equipped with this bundle of requirements, Reinhardt Hardtke approached the specialists at Beverungen Communications, with whom he jointly decided on the installation of the Christie devices as the perfect fit: The new Christie HD10K allows for a true HD resolution at 1920 x 1080 pixels, it provides the required 10,000 ANSI lumen, it is quiet and still manages to come along in the smallest housing in its class. Finally, the device works - just like all of the M Series machines - with a dual lamp system which, if needed, even allows changing the lamps while in operation. Ergo, a perfect solution!

Equally important for projection across a width of 19 metres with three projectors is the correct and matching display of the colours on all three screens. The HD models of Christie's M Series are equipped with a so-called "Yellow Notch Filter", that displays the colours in a most natural way and the same on all three projections.

The projectors at the Heinz Nixdorf MuseumsForum are used for presentations in lectures, e. g., with PowerPoint or other PC signals. But quite often video signals are also transmitted by live cameras or playback systems such as DVD. As for example at the „First Lego League“ competition, where this year 20 teams played against each other and had to manoeuvre their self constructed and programmed robots through a given course. In this case, the projectors are exclusively fed via DVI fibre-optic cables.

As routing system for the projectors, a Vista URS 1608 is used, where URS stands for "Universal Routing Switcher". The device, that was first used for the first time in Germany, is capable of accepting virtually any possible signal source, convert it and feed it in the new format to the outputs. There are 16 inputs for all analogue or digital signals which are also converted accordingly and at the end eight outputs which are capable of feeding a signal ranging from analogue component video signal to a digital 4K signal. Especially in such a multi-function environment, where many different sources are used, the Vista URS 1608 is the perfect choice since it can help to eliminate a whole array of various switches or cross-bars which ultimately might not work perfectly with each other. Here, state-of-the-art technology is used in the right place - at the Heinz Nixdorf MuseumsForum – the high tech museum.

But even the installation itself required and was an example of specialist handicraft, as Hardtke adds: "As always, the cooperation with Beverungen was absolutely smooth and with very quick response times, due to their proximity to our house.“

Working with the Christie projectors came with ease to Reinhardt Hardtke: "The setup of the projectors is easy and well structured, from the menu layout almost intuitively to operate. In fact the set-up was performed easily and quickly, as are any adjustments of the projection that might be needed."
