Can RealD type 3D be brought to home theaters on standard(non 3D) hdtvs?

[yungl1nk]

Im rly into the RealD 3D. if i could, i would watch every movie in that way. i just love how it creates a realistic depth to the movie. i saw my bloody valentine recently and was blown away by how fun and engaging it wuz. ive been seeing CES reports that panasonic is bringin somethin very similar to this type of 3d to homes soon but they only displayed it on a full 3d tv as i recall. i also heard that ps3 games will soon be utilizin this technology too. but is it possible to bring this to my set(located in my sig) besides the crappy anaglyph technique?

It can be done you would just need a brand new HDTV with polarising glass. And you would need special BD releases that carry both streams of the video. Which with current BD limit of 50GB would mean more compression. Hopefully by the time we do have polarised HDTVs they would have the 200GB BDs out.

The color polarizing technique used by RealD is only possible with video projection based systems -either a dual front projector setup or a rear projection screen TV system using DLP chips. However, no RPTVs in existence match the 144fps triple-flash frame rate used by RealD.

Full color home theater 3D is very likely going to depend on special LCD-based "shutter glasses" that are controlled by the Blu-ray player and/or the HDTV set. That's the only way the 3D material can be distributed to the widest viewing audience.

Most HDTV owners have a LCD-based flat panel television set. Those kinds of TVs will not respond properly to any sort of polarized system. Shutter glasses are the only method that will work. The same thing goes for plasma-based televisions.

Since the vast majority of HDTV owners prefer flat panel TVs (as opposed to bulky RPTV units) the LCD shutter glasses approach seems like a foregone conclusion.

The bad thing is LCD and plasma based TVs are usually running on 60Hz or 120Hz refresh cycles. They can't adjust down to a multiple of 48 -the dual ratio of 24fps standard movie film frame rates. That will leave movie studios with a difficult decision. If they want their full color 3D movies to work with the most HDTV sets they will have to encode the movies at 30fps rather than the native 24fps rate in order for the movie to jive with 60Hz and 120Hz displays.

In the long run a lot of HDTV sets will gravitate to the 240Hz refresh rate. 240Hz is a common denominator of both 48fps and 60Hz. One can keep the native 24fps per camera eye intact and also accommodate 30fps/60Hz material in 3D as well.

Can RealD type 3d be brought to home theaters on standard(non 3D) hdtvs?

the answer is most likely yes (BD is working on a real 3D spec) and most likely no (you would need a new TV and BD player)

To have real 3D each eye needs a different pic. There is the ever easy anaglyph method (shift the two colours and then have them together on the image and colour filtered lenses) but that is not "real" 3D so we will forget about it.

The other two methods commonly used are

asynchronous/ shutter glasses: In this tech the two images are not at the same time, but they are so short that it does not matter and as the images flip on screen (left eye, right eye, left eye....) so do the shutters in the glasses. Assuming the refresh on the TV is fast enough and the tech can have the glasses and display in perfect synch then this might be possible today

polarized: the easiest way to understand this is to think of light as a wave, if you take a rope and make it tight enough and move your arm up and down it will make a wave like | if you move it left right it will be like _ now if the wave is like | but needs to pass through = it will be blocked. So if one image has light "polarized" like |||| and the lens of the glasses like = it is blocked, but on the other lens which is like |||| it can go through (and the opposite is true for light that is polarized the other way).

No TV today can use polarized lenses but on the other hand all LCDs use polarization to work. So it should be relatively easy for projector solution based on polarized and might (not sure) be possible for LCD flat panels.

PS you can also have hybrid solutions, for example the display is asynchronous but the glasses use polarization

anything is possilbe with technology...

thought this was kind of cool too though

So, wait... Im confused (ignorant) as to why we can't just watch, say, the Real D 3D version of Avatar on our current Blu-ray and HDTV?

I know two camera's or something were used to create the stereoscopic effect (hence why its "blurry" when you lift off your 3D glasses), but the end result is still one image, right? Why cant we simply put that "blurry" image on a Bluray Disc and watch it on our current HDTV with the same glasses?

well this article says yes

OK it may be old news, but it s not on here so ...

I watched a REALD 3d programme on a 3d TV almost a year ago, during 3d conference at the Cineworld cinema in Canary Wharf, London.

It was not a main exhibit, and was there simply to show what was considered a pioneering 1950's 3d film (the Royal footage recently featured on Channel 4's 3D night) The films two elements had simply been transmitted to a RealD 3D ready TV.

We used the standard Cinema ReadD 3d Glasses to watch it. It was perfect.

When asked, a presenter explained that the odd 'lines' of the TV showed one eye in one polarisation, and the even 'lines' the other eye in another polarisation. (Normal TV pictures displayed as normal without the need for glasses.)

Why this system has not yet being launched, and we have been lumbered with expensive 'active' glasses, a technology that was discarded by iMax years ago, is beyond me.

How the content is delivered from the BD player or the broadcaster is irrelevant, it is how the TV displays it.

IF you are thinking of buying a 3D TV wait and make use of your collection of cinema glasses.
