Hello
I have a general enquiry about the operation of the 3D tvs that are being released to the world. It is just my understanding is that to create a 3D image the blue and red wavelengths are defocused on the broadcasted image and then by wearing a special kind of glasses (most simple case one lens red the other blue) causes the image to be brought back into focus and gives the 3D impression.
If this is the case surely the operation comes down to the broadcast and the glasses, so my question is what is it that the tv does?
Surely 3D channels should broadcast this wavelength offset, and by wearing these glasses we get the 3D effecr. Is this not basically how it works at the cinema too. They use the same screen for 2 and 3D films its just an offset on the broadcast (recording).
If the tv is having to create this offset then surely you don't need to subscribe to sky 3D as you should be able to watch any channel then?
So just to repeat the question: What exactly is it that makes a 3D tv special? How does it operate that requires a special device?
Thanks for any useful responses
Will
