Conventional TV displays objects only in 2D - or two dimensions.
3D TV displays objects in three dimensions, or stereography, and so mimics human sight. Because our eyes are spaced apart, they see the same view from a slightly different perspective. The brain combines the two perspectives into one image - and it is this process that 3D TV imitates.
When shooting 3D, two lenses are used to capture separate images of the same object from different angles. The 3D images contain twice as much information as conventional 2D images, and are edited while maintaining the information from both angles.
As you view 3D pctures, the left-hand image is shown only to your left eye, and the right-hand image only to your right eye. Your brain combines the two images, to give you a perception of depth.
In this way, 3D TV gives you an illusion of the third dimension, displaying the natural depth and presence of the real world. It brings pictures to life so that some images seem to 'pop' out of the screen.
This technology means you can enjoy movies, video games and TV shows in 3D - all from the comfort of your own home.
