Do you know how the 3D Television Technology works?

There’s a lot of talk about how great the new 3D TVs are and how the technology works but important information is often avoided,does it up-convert all programing to 3D or is 3D programing and/or additional hardware necessary to take advantage of the full 3D experience ! Just as an HD TV needs HD programing & a HD receiver or a Blu-Ray player to display a HD picture.

*PS: If you couldn’t care less about 3D TVs,think they are a waste of money or useless to you and are not planning on ever purchasing one,I’m glad for you but that’s not my question is about,directed your comments to someone who cares!
