ITU starts 3D standards work

No television transmission can take place without broadcasting standards being in place. The news that the International Broadcasting Union (ITU) has started its consultation on 3D developments, and will establish recognised standards is preparation for when 3D-on-TV might well be a reality.

Rapid TV News has already reported that one industry expert believes that existing test transmissions could grow, and that perhaps the 2012 London Olympic Games might well see actual 3D transmissions, no doubt to just a handful of suitable TV sets.

3D broadcasting on to TV sets (as distinct to cinema and theatre broadcasts) comes in two main forms. One technique is essentially to use spectacles, or filters to give each eye its own unique image. System 2 uses wave capture, which Bill Ray describes in an excellent report in this months Hardware magazine.

Ray says wave capture [makes] a proper 3D representation of the scene - comprised of voxels rather than pixels - and rendered using some sort of dynamic holographic display, or magic, depending on which is developed sooner.

Ray suggests that the ITU is less bothered as to display methodology just yet, instead concentrating on eliminating the dreaded eye fatigue (or more accurately brain fatigue) that seems to affect viewing of any existing 3D system.

He says the ITU is looking to complete its 3D work by about 2012.
