3D is all about seeing different pictures in each eye (close left eye, look in front, then open it and close the right one, see what I mean) Earlier the way to do that was to use colour filters and colour shifted images. then those two (usually one blue and one red) would be superimposed. This worked for a normal single film and normal DVD and BD. Every BD so far uses that method and since there is one simple image any TV can be used (unless you manage to find a B&W TV). Today, there exist better tech (at least for theatres) and what the BDA wants to do is bring it home. So you can enjoy 3D the way it should be seen.
