JVC has their D-ILA technology which they use in their projectors and rear-projection TVs, and which they claim provides superior quality. Still JVC seems to be positionned well over DLP and 3LCD in terms of price. They also are launching a 1000-something dollar 1920×1080 interlaced 27mbit/s Mpeg2 hard drive based camcorder.
Imagine having 3D charachters in your living room, those interacting with your furniture, walking around on your floor casting their shadows and reacting to a kick or a push that you would make. This is totally possible using this quite interesting futuristic real-time 3D rendering of 3D charachters interacting with pre-defined objects filmed with a High Definition camera. (would require some transparent High Definition video glasses to actually see the virtual charachters interact with the real world other than being able to see them on your HDTV.)
