Holograms

I was in the U.S. during the Obama election and I watched a report being delivered by a journo on site at the election hot spot however they where able to project her holographic image with the greatest of detail and no or little time delay to the studio.I've recently read that a university in Arizona has developed a new technology in this field.
I'm not much of a techno whiz(not sure if I'm even posting in the right area) and I think smart phones are the tool of the devil .

However this new technology has my interest and I wonder if one could do several images interacting with each other? Has anybody got an insight?

Its not a hologram, its camera trickery. They use chroma keying to remove the background from where she is, and superimpose her image over the feed from the other studio. Using a virtual studio, they can get the size of the image right. You'll notice that the camera is static, it doesnt circle around her. This is because tracking a moving camera is more difficult (but not impossible).

A virtual studio refers to having a 3D model of the studio, which also models your camera locations. Thus, you can render things, such as a feed from another location, in this virtual studio, which is then output to the viewers.

I used to work in broadcasting.

I do not think she was a holographic projection in the sense that if you were standing there in the studio you could walk around her ‘projected’ image. Its more matrix style where she was captured with multiple cameras and added to the live feed from the studio. So I guess them even using the term holographic is a bit misleading.
