[Slightly OT] Eurovision backdrop screens

Started by Mike G May 14, 2007
Firstly, my apologies to our friends over the herring pond for the
Euro/UK-centric nature of this post (although I'm sure you have
similar things in the US).

Watching the Eurovision Song contest on Saturday night, I was
impressed by the LED displays on both the backdrop and stage.

What sort of processing is involved in these massive LED screens? Just
getting them to sync must be a mammoth task. Do they make use of the
commercial chips from Maxim et al, or is there a more esoteric
solution.

I'm not asking for any trade secrets - I'm just interested to hear the
experiences from anyone who has been involved with this type of
project.

Thanks,
Mike

are you sure these were LED displays at all? I got the impression these were laser projectors Best regards Tsvetan --- PCB prototypes for $26 at http://run.to/pcb (http://www.olimex.com/ pcb) Development boards for ARM, AVR, PIC, MAXQ2000 and MSP430 (http:// www.olimex.com/dev)

The screens were various products made by Barco and driven from several media servers called Hippotizer, which is just a powerful PC with some clever software. They would have been run from one of the GrandMA lighting control consoles running the show, via DMX512 either over ethernet or directly. I thought it looked amazing, shame about thew music really.
