Is it Worth Investing in 3D TV Now?

What is actually 3D TV?

Before discussing this issue, it is important for one to have an understanding of what is actually the 3D TV we are talking about now.

3D TV

The short answer is that 3D television is a display technology that enables viewers in the home to experience TV programs, movies and video games in what is referred to as a stereoscopic effect. It relies on the use of stereopsis or separation, to add the illusion of a third dimension to an otherwise two-dimensional flat image.

Is it Worth Investing in 3D TV Now?

This illusion is created by simultaneously displaying two separate full-size but slightly different images of the same scene - one for the left eye and the other for the right eye. The differences in the two images are intended to mimic in very simple terms, the way the human vision system sees an object. The distance separating the eyes of a human being - referred to as interpupillary distance - helps the eyes see objects from a slightly different angle, leading to two slightly but distinct images. The brain processes these differences to generate among others, relative depth information to create the 3-dimensional image.

However, the way 3D TV generates a 3D image is not exactly in line with the way we see an object in space in that while 3D TV relies on image separation only, human vision uses both image separation and eye focusing cues to determine image depth. For many, this is not much of an issue in that image separation is often sufficient for the brain to determine relative image depth. However, this difference leads to a number of undesirable effects with 3D TV such as disorientation and in some cases, even headaches.

What is different from the 3D we have seen in the recent past is that now we are talking about a 3D experience that can support a 1080p HD image for each eye. Up to now, this was not possible.

Challenges of 3D in the Home

Well, 3D TV in the home has become a reality but... we believe that 3D Television still has to overcome a few serious issues before it will become a true mainstream technology in home entertainment.

In other words, it will still take a few more years for 3D TV technology to become the mainstream TV technology in the home.

Technology is still very expensive to be affordable by the average family. Suffice to say that at the present prices, a typical 3D Hdtv and two pAirs of 3D-glasses - (3D glasses are necessary for the displayed image by a 3D TV set to apPear as a 3D illusion) cost some ,000 more than a 2D equivalent Hdtv. And two sets of glasses are the bare minimum; you a pAir of 3D glasses for each member of the family viewing 3D TV content.

3D glasses - 3D TV's necessary evil: We mentioned the 3D glasses. The issue with the glasses does not stop at their expensive price tag (circa 0 per pAir). The added inconvenience brought about by the necessary 3D glasses is definitely something that not even TV makers know if the end consumer would eventually accept. You see, wearing a pAir of 3D glasses for an extended period to watch one of the latest Blu ray movies in 3D is an acceptable compromise. But to enjoy all your TV viewing with a rather over sized 3D glasses is another matter.

3D experience in the home is different from that enjoyed at the movie theater. While there is no doubt that the 3D TV experience in the home is definitely pleasing, yet it is less immersive and impressive than in the movie theater.

3D Content: True 3D TV content is a scarce resource and no matter what the movie and entertainment industry will be doing in this respect, it will remain so for a number of years to come in comparison to what you have in 2D. It is true that some 3D HDTVs come with a 2D-to-3D converter but this would be like the vague virtual surround you get from an old stereo recording.

Upgrade Reluctance: Many have just upgraded from their tube TV to a flat panel TV; some have even got a step further and purchased their second Lcd or plasma TV. These are still enjoying their 'new' HDTV purchase and I do not think that they will be the once to upgrade to the latest 3D TV technology - at least for now and at the present pricing.

3D TV: Image Or Reality?

Have you ever wished to jump into your favourite show and enjoy it live? Well thank the technology for taking you into completely different world. Latest technology in televisions can make you think twice to differentiate between image and reality. The basic techniques which can be used for 3D presentation are as follows.

· Stereoscopic
· Multi-view
· 2D plus depth
· 3D display

3D TV

These techniques enable the viewer to see three dimensional images. These moving 3D pictures can be created by special designed 3D glasses which send separate images to both eyes of the viewer or light source can be used to split the image which enable the viewer to see 3D images without glasses.

3D TV: Image Or Reality?

Companies are using different methods of technology to provide better quality 3D images to their customers. Philips, LG, Samsung, Sony and Panasonic have successfully launched various models equipped with latest techniques. These brands have been satisfying the needs of their customers for a long time and they have fulfilled the expectations of their customers in the matter of 3D TV as well. They are offering different packages to facilitate their potential customers and increase their market share.

You can find 3D TV on any electronic store near your house. Keep in mind that all the brands are not trustworthy and provide you the best results. Research is important. You will make right choice according to your need. Whenever you go to an electronic store always ask them for a test-run and decide after you are satisfied with the picture and sound quality. Always check the necessary equipment is included in the 3D TV set like cables and 3D glasses.

Another important point which you need to make sure is that the channels you watch are available to be played in 3D as this technology is new and not all the channels can be viewed as 3D but with the boom in this technology time is not far when all the channels will be available to be played in 3D.

Buy a 3D television and enjoy your favourite shows just like you are watching them live in the home.

3D TV Converter - Can You Change Your 2D Television to 3D?

With the recent release of a plethora of 3-dimensional feature films, the desire for 3D televisions in the home has risen dramatically. If you have seen films like Disney's Up or James Cameron's Avatar with special RealD glasses, you know that 3D can make one's viewing experience much more enjoyable. In fact, Avator has been critically acclaimed to have the best visuals of any film, ever (thanks in large part to its use of 3-D).

The problem is, although people want 3D in their homes, many people don't want to dish out the money for a new, "3D-ready" Lcd display. So, the concept of buying a 3D TV Converter has been introduced to the public.

3D TV

These 2D to 3D converters are surprisingly inexpensive: around 0. They have been around for a while (since as early as 2004), but have not had that much popularity. But in 2009 and early 2010, the sales of these products have shown a marked increase.

The problem is, these converters offer only cheap imitations of real 3D. They don't actually make anything 3-dimensional. Rather, these converters just split the image on your TV into 2 images, then uses polarized lenses to make the image on your display "pop out". However, the converters add no depth to the image.

On real 3-D ready televisions, the background of videos look like they are flush with the TV Screen, while objects on the foreground pop out. The difference between the background and the foreground is what makes watching 3D movies enjoyable. Without depth, you are just watching the same movie, except the whole thing looks slightly enlarged.

Are There 3D TV Shows?

3D technology has given the world economy a small boost. With rising popularity and increased technological developments 3D TV is now possible. You can view popular movies at the theater in 3D and now you can view 3D TV shows right from your own home. But this technology doesn't come without a price.

In the past few years the demand for 3D technology be it in cameras or in movie making has increased so, giving a good opportunity for producing three dimensional TV show. However, there are few risks to be taken care of. Many countries and channels are testing the technology of 3D broadcasting for some major terrestrial networks but currently, it is out of reach. But, for the satellite and cable networks broadcasting 3D TV show will be an easier task as its implementation is easier with its wide bandwidth frequency which cannot be applied for terrestrial networks.

3D TV

But there is news that channels like ESPN and Discovery Communications are going to launch their three dimensional TV networks, thus great news for three dimensional TV show viewers. Few others who have joined them are the sports unit of Walt Disney company will be launching ESPN 3D which has been advertised as the first three dimensional TV network in the industry will be beginning in June and will be having around 85 live sporting events in its first year.The Discovery channel has also decided to launch a dedicated 24/7 three dimensional TV networks in the US by the year 2011. For this it will have a partnership with IMAX Corp and Sony Corp.

Are There 3D TV Shows?

3D technology is not a new thing but it was mainly not successful earlier due to the problem of wearing special type of glasses which not only caused physical discomfort but also resulted in some news of health hazard, due to which it mainly remained confined to movies and sports. But with the recent development of 3D technology nowadays you need not wear special glasses to view three dimensional TV shows or movies or any events.

So, the 3D technology is now spreading its tentacles towards 3D TV shows as well which more and more consumers will be adopt with the development of the 3D TV networks.

Why Plasma 3D TV is Better Than LCD 3D TV

With the advent of 3D technology in television, TV manufacturers have been in a constant race on who's going to create the best 3D television. Newer technologies in the TV world such as Lcd, plasma, and LED are beginning to undergo immediate innovation and upgrade of specs - the integration of 3D technology. This leads us to thinking of what's superior: Plasma 3D TV or Lcd 3D TV?

The battle between plasma and Lcd three dimensional TV's is deliberately brewing, thanks to different 3D enthusiasts and TV technology critics. If you're just a regular buyer who's not really aware of the hardcore facts about TV technology, you will not be able to spell the difference. Display in both the plasma and Lcd 3D televisions would simply look exactly the same.

3D TV

However, it is interesting to take note that these two TV technologies have different ways of processing and displaying their content through 3-D. First, the processing speed of the two is totally different. While the Lcd technology has done several attempts of overhaul to improve its processing time (or "refresh rates" measured by the unit Hz) of 120Hz to 240 Hz. Though the refresh rate of 240 Hz (though some manufacturers claim of a 480 Hz, which is nevertheless already a manipulation of the specs) are already considered revolutionary for the Lcd technology, the issue with motion blur as well as side-to-side jerky panning is still an apparent issue.

Why Plasma 3D TV is Better Than LCD 3D TV

As with the plasma technology, which is quite known for a stable and superior processing speed, its measure of what it calls the "sub field motion technology" or "sub field drive" puts the processing speed very much ahead of the Lcd technology at a commendable 600Hz. Now, will that matter with viewing 3D? Absolutely! This means that Lcd 3D televisions are not able to deliver content in full High Definition 1080 resolution. LCD 3D TV can only deliver at most 800 pixels of effective resolution through its maximum processing speed of 240 Hz. Only Plasma 3D television has the speed to deliver the effective full 1080 resolution to both eyes.

Second, is the LCD 3D TV's 800 pixels of effective resolution to both eyes already significant? Well, not really as it's still considered high definition however, the issue on motion blur as well as panning issues of 3D content in a LCD three dimensional TV. These issues are never going to exist with a plasma 3D television. The depth perception of plasma technology plus the advanced pixel structure make for a superior 3D viewing display.

So why is the plasma 3D television better than the LCD 3D TV? Well, overall it has Roger Ebert's two thumbs up or a 4/4 stars. 3D viewing experience with a plasma 3D TV is absolutely superior.

How 3D TV Technology Works

3D television technology is becoming increasingly popular with each passing day. Due to the rise of popular 3D feature films (namely Pixar's Up and James Cameron's Avatar), major television manufacturers began developing three dimensional home television technology in 2009.

There are several methods that these manufacturers use to create 3D images on an LCD television; some are more expensive than others, and some are more feasible than others. This article will discuss the three primary methods of 3-D home theater technology that will be used in upcoming years.

3D TV

Lenticular viewing: This technology has been pioneered by Philips, and is available as of today. TV sets that use this technology can be watched without those funny glasses that audiences used in theaters. These Televisions use a lens that can send different images to each eye. That is, your left eye will see a completely different image from your right eye, which will emulate your two eyes' use of stereopsis (the process by which your eyes discern depth). The one weakness of lenticular viewing, however, is that a viewer must sit in a very specific spot in front of the TV. This means that only a couple people would be able to comfortably watch the TV at once due to its small viewing angle.

How 3D TV Technology Works

Passive glass systems: Hyundai is developing this type of LCD monitor which will allow both 2D and 3D images to be viewed. To watch the 3-D images, viewers will need to wear the traditional glasses in order to watch three dinemsional Media. This technology is nothing new: the TV has two overlapping images and the glasses have polarized lenses. Each lens is polarized so that it can see only one of the two overlapping images. This technology is very feasible and 40 to 50 inch LCD TVs with this technology are currently available for purchase.

Active glass systems: This system is very similar to the passive glass system, except rather than the TV doing all work, the glasses do. The glasses synchronize with the refresh rate of the TV, then they alternate the polarization of each lens, making the wearers of the glasses see 3-D images. With this technology, people could be watching a 2-D movie comfortably, then at will switch the movie into 3-D. This type of monitor is being developed by Samsung and Mitsubishi, but the downside is that the glasses could be very expensive. Some predict the glasses to be upwards of 0.

Pros and Cons of 3D TV

A few years ago I saw my first 3D movie at the IMAX. It was so realistic that people where putting their hands up to touch it. It was a lot like putting your hand through a laser beam. My only other experience with 3D movies were some faiLED attempts to revive 3D when I was a kid, but it just wasn't realistic. Then my mom shared stories about 3D movies when she was young, but they were really movies in different colors made visible by wearing 3D glasses.

Since then 3D movies have come a long way. They actually work, in fact, they can create a dazzling and immersive movie viewing experience. Avatar was a great example of a stunning 3D movie. Now that we have the technology to create these movies we also have the technology to view them at home.

3D TV

We can now rent and view 3D movies at home. We can purchase 3D movie Players and even 3D Televisions. So some of the advantages of getting a 3D TV is that you can watch cool 3D movies in the comfort of your own home. You can plant your kids in front of a 3D Disney or Pixar movie and there is a good chance that you will get an uninterrupted hour and half to yourself. Just think what you can do with that time, pay the bills, do the dishes, the possibilities are endless.

Pros and Cons of 3D TV

3D movies are not only a great way to entertain the kids there is talk of a 3D sports channel coming out. Even non-sports fans would probably be entertained by a 3D football or soccer game. For the more cerebral, Discovery is working on 3D nature shows. They already have several out that are shown at theaters, so now we can fly over the Nile or get a close up shot of an African river from our couch.

If you are a gamer, playing 3D games is just one step closer to virtual reality or at least a very cool gaming experience. Another nice thing about 3D television is that you don't have to watch all 3D all the time, but when it is time for a kids party or a family movie event, you have the capability to do so. Being on the forefront of the 3D TV revolution will be a fun and entertaining experience.

Some cons of 3D TV are the expense. The newer TVs are more expensive and all of the standards have not been set yet. We all know the disadvantages of being an early adopter. We also know that technology changes fast. For instance Phillips is working on a 3D TV that doesn't require glasses. Do you really want to have to have glasses for all of your friends viewing 3D when the hip neighbors can view 3D without the glasses?

Then again, how do we know that 3D viewing without glasses is quite as good as viewing with the glasses? The answer is we don't. Technology will ever be evolving and we can't predict the future. If you are in the market for a new TV anyway, you might as well upgrade and get a 3D model. With the money being poured into this technology there is a good chance it will be around awhile. On the other hand if your old TV is just fine there is nothing wrong with waiting until the technology and the prices stabilize a little more.
