mitsubishi are developing 3D display without the need of using specs but that is at least several years away from production

Okay, let's start with a 3D primer.

1) The codec to be used is MVC - Multiview Video Codec. It's a variant of H.264. Left eye video is encoded first and then the right eye video is compared to the left eye. The difference between the two is the differential data. The final data for that frame = Left Eye + Differential Data. That's why it's possible to deliver high quality digital 3D data, due to the processing speed of the decoder and other related equipment. The fact that the Cell can already decode 3 simultaneous H.264 1080p stream is what makes the PS3 capable of handling 3D BD. And because DVB-S2 uses H.264 for its HD signals means that Astro in the future can enable 3D HD.

3D HD is true HD full color format. It is not an anaglyph format!

2) 3D HD is format agnostic. That means it's not tied to any one TV manufacturer or 3D technology. Once decoded, it can work on ANY 3D HD TV or projector.

3) 3D HD being delivered is 1080p for BD. No word yet on how it will be for satellite/cable. It is NOT standard definition.

4) There are many types of 3D HDTV/projector that are being developed. The one's that is coming out soon by Panasonic, Sony and Samsung is the active shutter glasses. The active LCD glasses works by shutting one lens then shutting the other in rapid succession; this works because the TV will transmit the sync data needed.

The passive glasses works similar to the RealD and Dolby 3D digital cinema systems. The video is transmitted rapidly and using special polarized lens, the 3D effect is achieved. No word if anybody coming out with 3D HDTVs this way. In the movies, digital 3D is achieved using 3-chip DLP projectors.

Finally, 3D with no glasses. This is achieved using special coatings on the screen and rapid video switch by the TV. The only drawback so far is that it doesn't deliver as crisp a video as the two above methods. Another method uses single-user active head tracking. It tracks your head and layers the video according to the position of the viewer. Then there's the multi-user active head tracking, similar like the above but more complicated.

I prefer LCD shutterglass as polarize glass still give me some color bleed. Just watch avatar 3d and I feel that the color is not so vibrant. The solution now for 3D gaming is Nvidia 3D vision for LCD shutterglass (with 120hz display) and iZ3D 22" LCD monitor for polarize glass (anyone have a unit?)

CES 2010: 3D TVs on sale in UK by April

Watching World Cup in 3D and guess what LG is the first manufacturer to release this tech.

i  thought the next gen of 3D cinemas, LCD and bluray players dont need to wear glasses already, just with our naked eyes rclxub.gif
if want to wear glasses, it really makes no, our existing LCD and bluray players oso can oledi, just like hanna montana, jonas brothers BD, correct....
thats y now they produce new LCD ( maybe  they have different "screen" layers and 3D bluray players/disc ) to display it in 3D effect for us to view w/o glasses, next gen disc will potray 2 sided data side A (3D) side B (2D)
I'm also thought it is work like what you said...... hmm.gif

I used my "My Bloody Valentine" 3D Glasses to watch those movie looks kewl.

Hope more horror BD might come with 3D some days

sorry for a noob question..
but where can i buy the 3d glasses? i meant the normal blue/red ones...?
anyhow, i dont mind to buy a polarized 3d glasses like the one we used to watch avatar at the cinemas..
plz let me know yea?

I bought 4 pairs of good quality plastic frame red/blue 3D glasses from Amazon.com recently, $7.50 each

Like this http://www.amazon.com/3D-Glasses-Movies-Ga.../dp/B0035DRTJO/

It works with all red/blue anaglyph 3D movies and also NVIDIA 3D Vision Discovery for PC games.

But I only opened two of them to use, the other two still never open, just keeping for spare. You can PM me if you are interested to buy from me wink.gif

Already pm u. thumbup.gif


Added on March 10, 2010, 6:28 pmI see in news show sony lunch their 3D tv. But still we need 3D glasses. So no point to buy that one unless we can see 3D without glasses.

I think current HDTV also can support 3D if view with glasses.

The technology for viewing 3D without glasses is still very young, and very expensive to produce. It has it sets of drawbacks too, like you have to be in the middle of the screen, etc. You wont be seeing that technology soon yet.

The ones that will be coming out soon will be with 3D glasses. I've tried it before and it seems pretty good, but be prepared to spend a sum on it =D. You'll need the 3D TV, the glasses, and the bluray player. Also depends on content, but the potential is there. Its the beginning of a new stage in TV entertainment, but whether it catches up or not remains to be seen. But from what I see, i definately could get use to it =D.
