3D tech-agnostic set-top box designed
Displays 3D on any type of 3D TV, claim manufacturers
A standard way of displaying 3D content on a TV screen has yet to emerge, with manufacturers currently developing 3D-capable sets using a handful of different technologies.
The Sagem/Sensio STB works with any type of 3D TV, the makers claim
For broadcasters, such as Sky, this creates a problem. Transmitting one programme in a handful of different 3D formats just to ensure that it displays correctly according to all available 3D TV technologies will be very expensive.
Broadcasters will - once 3D TV services get going - probably therefore opt to transmit according to the most popular 3D display technology, leaving it up to consumers to decide which type of 3D TV technology is the safest option. Not an easy decision to make considering 3D TVs currently start at around £5000 ($8175/€5566).
Thankfully, two firms – Sagem and “avant-garde stereoscopic technology” developer Sensio, have joined forces to create a set-top box (STB) that they claim can handle all the major methods of 3D TV display.
A Sagem spokesperson told Register Hardware that four major methods currently exist: anaglyph, active shutter, micro-polarization and auto-stereoscopic.
Anaglyph has been around since about the 1850s and requires you to wear those red and blue glasses, which produce a depth effect.
LG's active shutter specs
Active shutter glasses create the illusion of a 3D image by alternately darkening over each eye in synchronisation with the display’s refresh rate. LG has already produced active shutter-based 3D TVs.
Micro-polarization can be used to create a 3D image by independently polarising pixels for your left and right-hand eyes – the Sagem spokesman added.
All three require viewers to wear glasses in order to see a 3D image, but the fourth technique – auto-stereoscopic, effectively sees 3D specs built into the display.
So SKY's current approach will lead to a nation of spectacle wearers having to put on two pairs of glasses to watch 3D TV? Back to the drawing board I think, not only for SKY, but for this set top box. Unless Specsavers are planning a range of prescription 3D specs for the future?!
never mind 3d
whats the point. I paid for a hd tv, and got Sky HD (£29), but show me where the take up of that is for every program on TV. not even Top Gear is HD, but last of the Summer wine is?
Never mind 3d, get me a full hd service first.....then maybe in about 5-10 years I might do 3d LOL
...An STB that can 'translate' any type of 3D TV signal for display on a non '3D TV' would be more useful?
If consumers want 3D TV, and Sky are likely to be the first to market with a channel then you can faily safely bet that which ever method they choose is likely to become the standard.. this would give a box that can display any 3D signal 'only' on any 3D TV a very limited market of wealthy early adopters that chose the wrong one.
And if they can afford to be an early adopter of 3D TV are they going to buy an STB to fix it or just buy a new 3D TV that works..
Really what is needed is a standard 3D Broadcast Technology, Then set manufactures can do what they wish to process the Stereo Image.
Who Defined Colour Television? the broadcaster or the consumer? Passing the Buck to the consumer only costs the consumer money, and stalls takeup (Bluray HD-DVD) when the manufacturers rake in double.. it ruins the consumer relationship. Broadcasters need to take the lead!
However that would rely upon the Broadcasters cooperating.. (how likely is that? how likely is monopoly commission involvement? kangaroo anyone?) or a big Broadcaster taking the lead (which wont happen if the guberment breaks them up!! or splits the licence fee amongst the others)...
Solutions exist, Government Quangos and greed prevent.
