Solutions: Wroclaw Stadium Display support


Two giant LED screens, along with a supporting broadcast system, have been installed at one of the venues for the UEFA Euro 2012 championships. But some ingenuity was required to put them into place, as James Christopher reports


Each 98sqm Mitsubishi Electric display has an 8mm pixel pitch and a 1600 x 960 native resolution


As well as hosting football matches, the stadium is also the venue for other major cultural, entertainment and sporting events


to three matches in the UEFA Euro 2012 soccer tournament, as well as a wide range of other major cultural, entertainment and sporting events this year. No modern stadium would be complete without large displays at either end of the pitch, and Wroclaw has been fitted with two 98sqm Mitsubishi Electric displays, and the supporting broadcast infrastructure, by Zabrze- based Shadok AV. “It is worth mentioning that some of


T


the equipment we offered represents the newest technology to be installed in Europe for the first time,” says Grzegorz Piechuła, Shadok’s owner, referring to the 8mm pitch vertical delta LED configuration from Mitsubishi. The brief was for a two-LED-screen


system, supporting a large number of connected display sources, including the management and mixing of graphical and video content, text, match scores, and recording of content for future use. The screens had to be of high quality and supplied by a well- known company that could support the equipment over its entire lifespan. The supporting broadcast system had to send and receive visual information to and from any point in the stadium. Shadok AV supplied two 12.8m x 7.68m screens made from Mitsubishi Diamond Vision ODX8 LED screen modules. Each screen has a 1600 x 960 native resolution (15:9, 8mm pixel pitch) at 6,000 cd/sqm, and can deliver high- quality images in all lighting conditions. The screens are driven by Mitsubishi’s most advanced digital display controller,

the XDC-6000. These feature Mitsubishi’s dynamic gamma correction technology and MPEG noise reduction to enhance image contrast and clarity of the image. The XDC-6000’s interlace-to- progressive scan conversion algorithm significantly reduces artifacts from the fast-moving content often encountered at sporting events. “A new 8mm pitch vertical delta LED


configuration together with other enhancements has enabled Mitsubishi to balance excellent performance and long- term reliability with very competitive pricing – factors which have helped it secure several more major stadium projects,” comments a Mitsubishi spokesperson. At the heart of the broadcast system is a UEFA-approved scoring and information system from Vizrt; this company also created custom content for use at the arena. Supporting this is an advanced multi-input video mixing Newtek Tricaster interface, while a Frontniche Blu-ray/HDD recorder allows the customer to store and back


up the current event. Thanks to a fibre network and a


plethora of digital fibre-optic converters, signals can be transmitted to any part of the stadium. The broadcast system can connect to any external TV transmission system, such as outside broadcast vans, and can send or receive high-resolution video all over the world. Installing the Diamond Vision


displays proved to be a challenge, as the schedule was tight and certain steps had to be carried out in a limited timeframe. So as not to damage the pitch, it was not possible to use heavy equipment to lift the support structure for the screens (which weighed over 4 tonnes) or the 300kg LED modules. “The biggest challenge for this


installation was choosing a fast and effective installation process for the support structure and screens, so they would be installed in the time schedule provided and with no damage made to the grass and the already finished works,” explains Jakub Kielar from Shadok’s videowall department. Shadok used several lightweight


electrical lifts with a support line system, along with forklift trucks to get elements into the arena without driving over the grass. This approach enabled support structure elements (the heaviest weighed over 1,100kg) to be lifted piece by piece, and assembled above the ground over four-days. LED screen modules were then lifted one by one and installed into the complete support structure. This took about three days per screen. Installation was carried out between June and September 2011, when the Mitsubishi equipment was used for the first time for public events. IE


To avoid damaging the grass, forklift trucks were used to lift elements of the supporting structure, and the display modules; these were assembled and installed off the ground
