Ask questions to Sigma Designs insider "kjack"

Why didn't they make 3D Blu-ray discs not compatible with current players, so that it would allow better quality 3D eg. including twice the bitrate and the 2D version for current players wouldn't be lower quality, and make it so that all 3D releases also included a separate disc with a 2D only version?

The same reason why Universal is trying flippers right now. There is no way the studios would sign onto something that would require them to ship 2 discs every time they want to do a 3D title.

The methodology they're using is actually pretty sound, since the difference between the left and right frames is pretty slight as far as MPEG compression goes. Remember that MPEG is a very fluid and dynamic medium, and you can do a lot with a little. That's why you get a spike when a shot changes, and then it's way down after that for example
