Royal Carribean, a cruise line, installed 80" monitors in interior staterooms in order to mimic windows. They mounted two Red EPIC cameras, one on the pointy end of the boat and one on the flat end, and are distributing a live video and audio feed to the monitors. They call it a "virtual balcony".
The challenge was to have the audio and video feed exactly in sync with the motion of the ship. Having the video out of sync would have caused motion sickness. They distribute the video via fiber to set top boxes, and have, they claim, all but eliminated latency. It would be really interesting to find out how they did it.
In other news, I'm pretty sure I saw this technology on an episode of The Jetsons.
Any thoughts?
