3D TV Ready for April 2010...............

Wow I just got a Plasma :dontknow:

but makes me wonder how the glasses will work, the Red Blue ones don't work for me as I only have vision in one eye (less than 10% in other) they only look like daggy sunny's but I would assume you need vision in both eye's :dontknow:

mrs is blind as bat without coke bottles so will they work for similar people, really is it just another waste of time? me I will wait, I looked at a plasma a few years ago and around $4,500 - $5K the one I got the other day was $899 on special (Panasonic Plasma not LCD) was same size as one I looked at before 42" (yes faye I know about Teresa's Kitchen)

TV makers are gearing up to launch 3D TV sets in Australia from next month but overseas pricing reveals a steep price premium over existing models, with a family of four required to spend $US600 on glasses alone.

Samsung's 3D TV range will be launched in Australia next month, followed soon after by Sony's July launch - both riding off the back of recent popular 3D movie releases such as Avatar and Alice in Wonderland.

Overseas pricing, announced this week, reveals the TV sets alone will cost several hundred dollars more than equivalent existing sets.

But it's not just your TV you will need to upgrade - a new 3D-ready Blu-ray player is required (unless the user owns a PlayStation 3), as well as a new HDMI cable and pairs of 3D glasses.

Australian TV networks, unlike their US counterparts, do not appear to be gearing up to offer any 3D broadcasts, but movies on 3D Blu-ray discs will start hitting the market alongside the new TV sets, and game developers have flagged significant investments in true 3D games.

The porn industry, known to be quick to adopt new technologies, is also jumping on board the 3D bandwagon.

Samsung's $US400 3D TV price premium

Samsung this week unveiled US pricing for its broad 3D TV line-up, which includes LED-backlit LCD models, regular LCD models and plasma sets. The 40-inch, 46-inch and 55-inch versions of the LED C7000 model retail for $US2000, $US2600 and $US3300 respectively.

The cheapest model is a 46-inch set in its low-end LCD 750 line, which will sell for $US1700. The flagship 55-inch UN55C9000, which can automatically convert 2D content to 3D, will sell for $US7000.

On top of that price, in order to experience 3D, users will have to pay $US150 for each pair of 3D glasses and $US400 for a new 3D-ready Blu-ray player. Glasses obtained from the cinema cannot be used at home as they are based on different technology.

More costs are added once consumers start buying 3D Blu-ray movies to play on their shiny new equipment, while 3D glasses from one brand will not work on TVs made by another brand.

The prices of the 3DTVs are several hundred dollars more than the equivalent existing TV range. For instance, the 46-inch 3DTV version of the LED C7000 is $US400 more expensive than the list price of the 46-inch B7000 model.

CNET's TV reviewer, David Katzmaier, noted the 46-inch LED C7000 was selling on Amazon at a discounted price of $US2350.

"That's a $350 premium compared to Amazon's price for Samsung's closest 2009 non-3D equivalent, the UNB7000 series, while the company's closest 2010 non-3D equivalent, the UNC6500 series, is listed at about $250 less," he wrote.

Panasonic has announced more aggressive prices for the US market, with a Best Buy deal offering a 50-inch 3DTV, 3D-ready Blu-ray player and pair of glasses for $US3000.

Sony customers slugged 50% extra

Sony, meanwhile, this week announced 3DTV prices for Japan, with a 46-inch set selling for $US3898, which the BBC reported was 52 per cent more expensive than a regular Sony flatscreen television set. Its 3D TV prices range from $US2444 to $US6444.

The more expensive Sony 3DTV models include two pairs of glasses but cheaper models are 3D-optional, and can only show 3D content after additional accessories, including glasses (about $US133 each) and a 3D transmitter, are bought.

Neither Sony and Samsung would reveal Australian 3D TV prices but a Sony Australia spokeswoman said "our intention is not to make the products much more expensive than last year's premium, high frame rate BRAVIA models".

Kogan's not convinced

But not all TV makers are gung-ho about 3D. Ruslan Kogan, founder of Kogan Technologies, an online retailer of low-cost Kogan-branded TVs, said the consumer electronics industry needed to stop looking to 3DTV as a solution to falling profit margins.

"Can you really imagine sitting around with a bunch of mates, drinking beer and watching the footy, all wearing clunky 3D headsets or glasses? Let alone sitting on a couch with a partner, leaning in for the clichéd kiss, and locking headsets instead of lips," he said.

Kogan said the future of TV sets was not 3D but internet-enabled sets that enabled people to "watch streamed content on demand, make Skype calls, and access the internet through their TVs".

3D relies on faking your eyes out by utilizing how your brain perceives depth perception with 2 eyes.

Ok this is what I think is happening... please correct me if I am wrong...

Modern day 3D (not red and blue glasses) uses polarized lenses which means a "3D" image is actually 2 different pictures somewhat out of phase with eachother superimposed on eachother. It's basically the same principle as old school red/blue 3D. The difference is that red/blue glasses filter the color of light, modern day 3D filters the polarization of light so that modern 3D allows a full color 3D. Ever notice how a modern day 3D movie looks blurry without the glasses? With the 3D polarized lenses, one image gets to the left eye, the other image gets to the right eye so in order for your brain to see an image clearly your eyes must slightly change their viewing angle (not focus) in order to get the 2 separate images to look like they are on top of eachother and therefore your brain develops a sense of distance based on the severity of eye crossing. images that are percieved to be closer require your eyes to cross in towards eachother more than images that are supposed to be perceived as off in the distance.

Just have your wife put her finger in front of her nose and try not to laugh as her eyes cross. Tell her to keep her finger there and then look off into the distance and ask her if she perceives 2 fingers. That is what 3D movies + glasses are relying on in order to give you a sense of a 3D image.

Now of course in real life you're eye(s) also have to change their curvature in order to focus images depending on their relative distance but in 3D the focus stays the same and only the direction that the eyes are pointed towards are changed.

p.s. I think there was a middle ground between red/blue 3D and modern day polarized lens 3D where they actually had glasses that flickered (dark/clear) to control which image gets to each eye. Sort of like how your brain perceives a continuous movement even though displays refresh a certain amount of times a second which you can catch by videotaping an old TV and then taking notice of the lines that form on the TV in the video.

http://en.wikipedia.org/wiki/LCD_shutter_glasses

shutter glasses is the term for the ones that flicker and they require a power supply and some sort of way of making sure the timing is right such as using either a wired or wireless connection to the tv so that they are flickering/shuttering in synch with the image. LOL if it was out of synch and the right eye was receiving the image that was destined for the left eye and vice versa...

Avatar uses RealD Cinema which relies on circular polarization of light... clockwise for the right eye and counter clockwise for the left eye...

It's been a very long time since I took an optics class in college so I'm not even going to try and think about what that means! :notworthy:

gahh go away E X M 3D charts and cross products you are not welcome in my head right now!

Lord Viykor

No good for me ages in them.Nocky, I've got limited vision in my left eye. I can't even see images in those odd splotches that were all the rage in the early 90's

Nocky

Yes LV I have 10% vision in my right eye, I did watch avatar and got some effects but is TV going to be as good, I don't really care that much can't see the value of watching BIN Ladin through missiles at me in 3D on the news

Thanks for the in depth explanation Mikey :thumbleft:

optics wasn't one of my better subjects in school though

Dufflight

I'll stick with plasma and blueray for a few years. A lot of new stuff gets replaced quickly as they work out the bugs. And after a few turkeys does it really matter. :dontknow:

I've had a 3D TV for years, it is an 80cm x 40cm x 40cm CRT

heh shutter glasses work very well with CRT displays that have very high refresh rates

himzol

I think I'll give it a miss, I keep having images of the biggest loser "weigh in" in three D.. :shock:

machineman

I thought that modern 3d was a polarization setup. But my regular Polarized glasses didnt work at the theater when I tried them. I think they use some other form of polarization.

RupertofOZ

Yep... I'll wait for the complete surround holo-deck.... :wink:

Delgrade

im with you rupe, full suround holo and im in

Cheers

RupertofOZ

It's probably not as far away as you might think Pete... 3D confined with the box, is the first step...

The other component of full motion sensor interaction...(controller free)... is a reality... albeit wireless at this stage.... i.e. Wii ... and the forthcoming Xbox 360 "Natal" project... (which will blow the gamers socks off)....

A full surround holo deck would incorporate 360 degree motion sensors by default...

Someone just have to get the "projection" nutted out.... it's already been demonstrated that holograms can be transmitted... "streamed"....

Indeed there's even, or about to be released... a form of holographic computer storage....

beam me up scotty?
