Actually it is called DVI for Digital-Video-Interactive. The technology was
shown by RCA (and developed by them) but *no* product plans were announced.
It is an amazing system, and the chips which were designed by RCA and 
produced by some custom silicon house consist of a video processor and
program storage. One of the things the video processor can do is 're-map'
video so that a frame taken by a 15mm fisheye lens can be viewed 
interactively by the viewer who can select the viewing angle from 90
degrees left to 90 degrees right, thru 90 degrees up or down. The video
processor remaps these views from the one fish-eye view. This makes things
like the MIT 'Walk thru Aspen Colo' possible with a lot fewer frames needed.
It isindeed a neat and wizzy technology.

I believe EE Times also had an article on this stuff.
