I don't know all the tech behind it but you can't watch 3D on an older non-3D TV.  

This article explains the various technology alternatives.

B&O has to be pro-active on this new technology.. 2010 CES show marks the great push for 3D for Television viewing. With ESPN, Disney commiting to broadcasting sports on 3D, its only time before general public is going to accept this medium. I know, even though the idea of wearing glasses in our own home viewing television seems to be silly at this point, my guess is the consumer will eventually accept it.. how cool would it be to watch NFL football or World Cup soccer in 3D..

I hope B&O doesnt miss the boat as it did with Apple Ipod.  Can you believe B&O doesnt have an ipod dock yet, when every imaginable company make something for apple ( like the jogging shorts I picked up last week, which has a special pouch to hold your ipod 🙂 ) ohh but they have a $20 ipod cable..
