The highest profile and earliest proper 3D stuff I remember was TVS's The Real World (ITV doing a science show - truly a different era...) experiments ISTR. They did a couple of shows on 3D TV and also showed The House of Wax (a 50s/60s 3D movie) I think this was quite early on in the TVS franchise - 1982/3? The glasses came free with the TV Times.

Edit - 1982 : Here it is on YouTube : http://www.youtube.com/watch?v=7VA8MYi1vYk and here : http://www.youtube.com/watch?v=xZheFIa3KzM&NR=1

It used the anaglyph (?) red/blue coloured glasses system - AIUI the C4 stuff is using a different coloured glasses system.

The BBC used a fake-3D system using the Pulfrich (sp?) effect in the 90s for Children in Need - which uses a neutral density filter over one eye (to dim the image - which the brain perceives as coming at a different time to the full-brightness image) and multiple planes of tracking motion (to generate parallax) They did a Doctor Who and a Pet Shop Boys performance (with a handheld camera cabled from the lighting grid to allow it to go round, and round, and round, and round the performers) using it - but although it had a sense of 3D depth when the camera moved, the minute it stopped, the image flattened.

And here it is from 1993 : http://www.youtube.com/watch?v=mx-OwFxOFjs
(very nice DVE move in it!)

The blocks were probably used cause of the 80's being when 3D telly was first attempted [poorly]... so they used an appropriate ident to fit the era.

Plus they're always looking for places to use it aren't they. Laughing

I wonder if Lambie Nairn were involved making the new blockless version of it, or if they just tweaked the old footage. I know after talking on their YouTube channel that they'll be uploading some of the block idents as a showreel soon on their page.

The US TV show Chuck was recently shown in 3D. And there have been a raft of 3D movies recently - Bolt for example.


3D Movies are a different kettle of fish, as are the 3D pilots that Sky and SISLive (formerly BBC OBs) are doing.

3D movies use a much better system for eye separation than the anaglyph (?) style coloured glasses. Most use polarisation (where projectors project two eye views but use either linear or circular polarisation and matched polarised glasses to ensure each feed gets to one eye only), but Dolby have a clever system that uses two different wavelength primary colours for the Red Green and Blue pixels for each eye feed in the projector and has narrow wavelength diffraction filters on each lens in a pair of glasses that only allow one of the two pairs of primaries to get through each lens.

This ensures full frame rate, full colour images are sent to each eye.

The TVs that Sky's system will feed could use the above techniques, but could also use the LCD shuttered glasses (where each eye is blanked alternately - but this can cause quite nasty flicker perception) system, or lenticular screens which don't require glasses (but aren't great when you move your head even slightly - so are tiring to watch)

The 3D TV stuff that has aired on conventional outlets (rather than closed tests with special kit) is still very compromised - and if anything could do the reputation of 3D TV more harm than good as it re-inforces the coloured glasses, rubbish picture quality theory. (And doesn't work at all well if you have your TV set-up with non-ideal picture settings - particularly the wrong colour temperature, gamut and over saturation)
