3DTV | Are We There Yet?

I know what you’re thinking, “I just bought my HDTV, what’s all this 3D business?” 3D is expected to be the next monumental breakthrough in the history of television. In this Tech Tip, I’ll cover the basics of 3D TV, including some of the different technologies and how they work.

How it works: three dimensional television (3D TV) uses a method known as stereoscopy to display two different images to your eyes so that they appear as one image. As your brain interprets what your eyes are seeing, it combines the two images while your eyes are still focusing on the source of the images behind them. This creates an illusion of depth to the viewer. The phrase, “There’s no such thing as a free lunch” holds true for fooling your brain, too. Long viewing sessions of stereoscopic images or video strains your eyes and can result in headaches. Worse yet, a small minority of people can’t see stereoscopic images or video at all due to any number of medical conditions that prevent their brains from being fooled.

  1. Hi David:

    Re: your 3D TV article, just a quick grammar lesson, which you clearly need!  If you lay something onto a TV screen or whatever, then it is “lying” on it, NEVER “laying” on it!  It’s so very un-classy to use “laying” when someone or something is “lying” there.  It undercuts your usually excellent commentary to make this common mistake, hence my picky email.  Hope it helps!

  2. Have a Sony 3D since Decemeber. It’s awesome. I don’t get have any problems with watching 3D and neither do any of my family members. You will always find a small group who have nothing but complaints about everything.

  3. Outside of epilepsy, the only positive result from all the 3d hoopla has been giving something to write about.

  4. My friend recetly purchased a 3D TV & it’s pretty cool.  There is only one chanel avaliable at this time, a sports chanel (football & free style bikes are sweet in 3D).  They got quite a few movie out there in 3D now.  I am impessed & really enjoy watching!  I don’t think I will have one anytime soon, but if you are able to purchase non practical items the 3D T.V. is definatly a really cool thing to have for the rainy or cold winter weekends grin

  5. I see this as another way TV companaies are trying to get us to buy more adapters for our TVs. Right now it is still in the gimmick stages.  Personally I cannot see enough of a difference between Blu-Ray and regular DVDs to justify the extra cost of the blu-ray player and the cost of blu-ray disks.  I see this technolgy 3D as almost the same thing - it will be great when it is really ready - but why rush you may be waisting your money like 8-track buyers and the beta tape players when vhs won out. thaks.

  6. Two things-

    First, in describing the Anaglyph lenses the text does not agree with the image of the glasses. Right should be left and left should be right.

    Second, a minor grammar mistake-
    “...only a small install base of 3D-capable living rooms.”
    install should be installed.

  7. 3D success in predicated on another issue that was not covered in the article.  The content (movie, tv show, graphic) must be rendered in 3D.  If there is insufficient interest in 3D, then the technology fails.

    Will 3D succeed in the future?  Yes, however it will be a disruptive path.  Someone will develop a cheap, viewer independent technology to display 3D and it will be considered a toy or not technologically robust, but it will succeed.  Entertainment rules now, but in the future it will be used in medicine, education, robotics and navigation.

  8. Do any of the TV manufacturers currently make an Auto 3D TV, regardless of size or cost?

    How would I recognize one of them, if I even saw it?

    Or, is the Nintendo 3DS capable of streaming 3D video?

    Can the Nintendo 3DS connect to a local area network, to stream network available movies and videos?

    Is the Nintendo 3DS capable of sending its video output to an external monitor in addition to its local screen?

    TIA

  9. It’s very good Information about 3D.
    Thanks

  10. The 3D Demos that I’ve seen so far were interesting, but hardly worth the $… in fact, everything looked so “something-pasted-on-a-flat-background,” it looked LESS realistic to my eyes.  Much like early surround movies, in which the side fills were silent and all of a sudden a roaring motorcycle or something blasted forth.  I imagine (I’m old, but not that old) that early Technicolor and even talkies suffered the same way.  Bottom line, call me in a couple years… unless of course the Mayan Long Calendar really does predict the end of the world and not just end next year because it’s a looping point. :-<)

  11. Having watched Avatar in 3D 6 times on the BIG screen, with glasses, I was WOW’d by the special effects.  I’m sure there is more that I didn’t see than what I did.

    I look forward to 3D in the home. Sony has the best set up currently, in my opinion, but who can afford it to watch a few of the 3D movies that have been produced.

    Standardization is a must.  Remember Beta vs. VHS? I bought the 21” laser disk player back then. VHS won out. I joined Video Depot with a $100 lifetime membership, their lifetime of about 6 months. I was a Gemco member, a Fedco member and so on.

    Now I look forward to 3D without glasses. It’s coming. I even hear that holographic technology is in the works so we can watch everything in 4 deminsions. I’m not sure I’ll live long enough to see all that the future of technology holds. I’m just ready to get all I can before I depart for my eternal life where technology if greater than anything man can conceive with his pea brain.

  12. 3D is a waste of tome and a step back in technology!!!!!! Holographic imaging is the next generation. All the 3D manufacturers are trying to do is get people to buy cheaper to make TV’s for a higher price. Take one apart, and price the display for your self. It’s a standard non-High Definition display that can be purchased for 30-70% cheaper than a HD display. I replace displays for the military and have had to replace 2 this year!!

    Have a good one
    Robert

  13. Great post but I feel 3D tv is just a phase and within a year it will be a forgotten tv model. I don’t think the technology is advanced enough yet.

  14. I just bought a Vizio that uses the same circularly polarized lenses that the the movie theaters use. No batteries, no flickering, and the glasses are about $25 a pop (or less if you find a source for the movie glasses). The only drawback is that it essentially halves the resolution of your display, as half of the pixels are polarized for the left side, and the other half for the right. But the 3D effect is quite more profound than being able to count the rivets on the Titanic, so it’s a positive tradeoff in my book. The set also works beautifully for 2D 1080i.

  15. How about the Carl Pilfritz (sp) effect?  I first read about this in a “VIDEO” magazine in the “90’s” This is where you place just one lens of a normal pair of sunglasses over one eye.  Doesn’t matter which one.  The brain then does the math and produces a parallax 3D image of any normal TV image, that uses alternating NTSC.  The only caveat is there must be motion present.  You won’t see 3D if you are watching motionless video such as a newscaster.  Works great for football, basketball where there is lots of motion.

  16. Although the glasses themselves have been getting smaller and lighter (especially in the case of passive technologies such as FPR) I am sure many people will agree that we will only be ‘there’ once we can do away with the glasses entirely. The ability to view believable and comfortable 3D images from any angle and viewing distance would be nothing short of evolutionary for the this technology. There has been good progress but we still have a long way to go.
