Well, all that might just be changed soon by the Italian Broadcasters and Technology Consortium. So what are they trying to achieve? Well, basically they’re combining both the left and right 720p frames into a single 1080p broadcast frame. This is then transmitted in such a way that the 2d televisions only pick up one part of the frame, while the 3d televisions have access to both parts, and will then do their overlaying magic to give you your 3d broadcast.
While this “backward compatible” technology will save a lot of money, it also means that standard HDTVs (not 3D enabled), will only get half the image data streamed, essentially making it half the quality.
The technology is being looked into by the standards commissions, but it might be a while before we see it hit the mainstream.
