Details

Media artists often need to play multiple videos on multiple screens in loop for long time. Often they also want to play all videos synced (i.e. all of them starting at the same time). Having one device (for example a computer) playing all videos requires expensive and complicated special hardware if you have more then three videos and screens. An easier way to achieve this, is to use seperate media players and screens and to sync them using a common or special infrared remote control. That's what this project does.

Currently used in the Kunsthaus Wien

Currently an IRremoteSync is used in the Kunsthaus Wien in the exhibition "SHOEting Stars":

(I assume this link will point to another exhibition in future.)
Short videos (10 seconds) are played on two screens using built-in media players. The videos have exact same length, but also if you start both media players at the same time, after some while the two loops drift apart. Every hour the IRremoteSync sends IR commands stop and after a short delay start to keep the two independent video loops synchronized.
