The BBC research department has been quietly working on 3D TV. It plans to
cover TV screens with tiny hemispherical microlenses, each of which magnifies a
four-by-four grid of pixels. By sending images taken from slightly different
angles to the groups of pixels (GB 2358980), viewers will be able to see the
picture from different perspectives if they move, instead of seeing it as
standard flat 2D. The effect is claimed to be akin to a video hologram. Digital
compression of the image data helps the system cope with the vast amounts of
data created by multiple shots of the same scene.
