STATE OPERA FOR ALL 2013 For the third time in succession, we were invited to provide our LED technology for the Staatsoper für Alle (State Opera for All) event in Berlin. An audience of 38,000 people followed the event in fine weather. 3 video walls were used for the event - as well as a 30 m2 Eviwa Screenbox. The rear LED wall was located over 150 m away on the hotel roof terrace. The video signal from the high-resolution outdoor LED wall was controlled using video time delay that allowed the audience to experience the pictures in synchronisation with the sound transmission.
