Hey there.
If anyone is interested, the technology is quite simple.
basically, a HD camera array forms a circle around the subject (IR is used for tracking information), the information is sent to a computer (bank of computers) and is crunched then transmitted to the receiving end where another bank of computers decodes the information then sends it to a high resolution, high lumen projector which projects the image onto a clear screen.

see Pepper’s ghost:

for information on how this technology can be implemented, but basically it works like a heads up display with the image being projected on a clear see through screen
One interesting and new aspect of this technology is the use of a really cool product by 3M called Vikuiti (vi CUE ah tee) which lets the clear see through projection screen reflect only the video image.
