percy, the standard blue/green 3d stuff can be transmitted and watched without incident.

the actual tech behind this new "3d" isnt actually all that clever and has been around a while! its just been that non-CRT screens have not had the ability to do a good enough refresh rate so its not been adapoted.

now that you can get 120hz LCDs people are using it more.

it very simply just displays 2 different images (1 for each eye) alternately in each frame, and the glasses simple have shutters (well, equivalent of) that cover over each eye seperately as each frame is displayed.

the TV itself is not "special", othe than its refreshing at 120hz rather than 60hz!
