Hum, where did I put my pedant hat... hum not here, not here... ah there we go. Hum hum
That's stereoscopic television, not 3d TV. I personally don't enjoy that much stereoscopic images, they don't look really believable to me. Stereoscopy is only one way we build a 3d model of our environment, the parallax created by our recent movements creates an accurate map too. Sure if you lose an eye, you'll have much poorer depth perception, but you won't lose it all. If you cover one eye, the world outside doesn't start looking like a TV image immediately... if you stay still for a long time it will, because you forget the parallax information you gathered.
Look at the wii headtracking videos on youtube... even though you're looking at a video of a guy simulating 3d on a video screen, it'll look 3d.
A real 3d TV would be holographic... it's waaay more complicated to make than movies this way. Rendering 3d animation in holographic format is doable but would require much more memory and rendering capabilities on the playback machine. The device is also much more complicated to build, but with 3 colored laser and a dlp system fine enough to change the phase of each pixel, it's doable.
To the point... where's my holographic tv!!
