3D TV QUALITY

It seems that 3D TV is becoming quite a desirable item for the consumer. According to surveys, around 46% of American people want to have a 3D television in their home.  It is predicted that over 1.2 million consumers will purchase a 3D television by 2011. 3D television is one of the newest breakthroughs released by the television industry on to the market.
                     
3D televisions have their advantages and disadvantages. The great advantage is you can experience excellent quality pictures in three dimensional images from the comfort of your own living room. You don’t have to go to a theater to enjoy 3D films. It is also has great potential for people who love to play computer and video games.

The disadvantages include the following. 3D television is not yet fully developed and is still in its infancy. You have to watch 3D movies, events, or channels using 3D glasses. You cannot see the three dimensional images without wearing these. Plus, you have to sit directly in front of the television for you to see the images as it is not a possible to view effectively at a wide angle.

Purchasing a 3D television is also more expensive than other television conventional models. Normally, it is higher by around $200 to $300 than a full high definition TV. There are also people who might have problems watching 3D images. These are people with amblyopia also called lazy eye and people with astigmatism. People that have astigmatism will have problems detecting the depth of the 3D images.

3D TVs can already be purchased now in the market. Mitsubishi and Samsung have already begun selling 3D ready televisions to the market. Some leading television manufacturers have already started manufacturing the 3D television and some are developing how they can offer 3D television without use of the 3D glasses.

With the recent release of some block busting Hollywood movies in three-dimensional format, most notable of all being Avatar, which became the largest grossing movie of all time, 3D technology has been back in the spot light. 3D television technology is actually nothing new, in fact three dimensional film technology has been around since the 1950’s.
                            
3D is quite simply the filming of motion picture in such a way as to increase the viewer’s perception of depth, creating the illusion of the film jumping off the screen in such a way as you feel like you can reach out and touch it. The high cost involved in the production of 3D movies is the reason that there has been such a long gap between the creation of the technology and the recent release of televisions. Three-dimensional movies had a surge on the late 1980’s and 1990’s when IMAX cinemas brought them to the general public. During that era there where attempts to break the 3D home television market, many people will remember the rather flimsy cardboard glasses with red and blue plastic lenses. This turned out to be a passing fad as there was limited TV to watch and quality was quite low. It would be fair to say that the latest re-emergence of television technology is here to stay this time.

3D TV FEATUREs

Los Angeles based broadcaster High TV is to launch the world’s first international 3D TV channel which will feature a mixture of entertainment, reality shows, and lifestyle programming in 3D.
                 
Currently in the UK, BT Vision shows 3D content through its BT Vision TV on demand service, and Sky have the  Sky 3D channel which shows various programming in 3D such as live Premier League football.  High TV would be the first internationally available 3D TV channel and claims that it will show around 450 hours of HD 3D programming.  It also claims that it will release the largest 3D TV on demand library with more than 450 hours of entertainment and movies in 3D at viewers fingertips.
High TV will be available to digital TV providers across Europe, and may be available on Sky TV packages, and BT vision packages which also include BT Broadband

High TV will be launching it's new 3D TV channel in April

The new channel will be distributed in Europe by RRSat on the Eurobird 9A Satellite, and the MEASAT-3a satellite across the Asia Pacific regions.  RRSat Global Communications network will provide uplink services for the new channel.

Head of Business Development at HIGHTV Gwenael Flatres said “High TV aims to take 3D TV beyond the limited and local audiences it is currently geared towards,” before adding “By utilising RRsat’s state-of-the-art technological capabilities and wide reach of the RRsat Global Network, we are capable of taking 3D programming to a global market, entering a new chapter in TV history with 24 hours of non-repeating 3D programming, seven days a week.”

The new 3D TV channel should be launched in Europe on the 4th April 2011.

Most new 3D models advertise "Full 3D" capability. There are many different formats for 3D video. A "Full 3D" television will accept any of these formats, including the highest resolution available: 1080p field sequential 3D. For a good explanation of the 3D video formats check out this excellent article at PRACTICAL-HOME-THEATER-GUIDE.

If you own or purchase a Mitsubishi DLP 3D-TV do not worry. Mitsubishi sells an inexpensive converter box (model 3-DA1) so that your DLP-TV will accept any 3D formatted video. Additionally, most PC's and 3D Blu-Ray players will convert 3D-DVD movies to the DLP's "3D Checkerboard" format without need for the converter.
The highest resolution 3D, 1080p field sequential, will have to be downscaled to DLP television's 3D Checkerboard format. In theory this downscaling will cause some loss in visual clarity. The operative phrase here is "in theory:"

Satellite and cable 3D broadcasts do not use full 1080p 3D format. Don't expect to detect any more 3D clarity on a "full 3D" set while watching 3D TV channels.

The only 3D-DVD titles currently available are low-detail animated titles (e.g. "Monsters vs. Aliens"). Again, don't expect to detect any more 3D clarity watching this genre.

Video in full, 1080p formatting is rare and will probably be a long time coming.

When using Playstation 3 to watch 3D-DVD's you will only obtain top-bottom formatted 3D even with a 1080p DVD.
The difference in clarity between full 1080p and 1080i checkerboard 3D is barely noticeable to most viewers.
   
In 2007 manufacturers Samsung and Mitsubishi released a line of "3D-Ready" High Definition DLP televisions. Today additional manufacturers are selling 3D-TV's, including Panasonic, LG, and Sony. Let's cover some features of these new products:
                       
    DLP, Plasma, LED and LCD 3D technologies
    "Full 3D" vs. "3D-Ready"
    3D Glasses for the new 3D-TV's
The pro's and con's of Plasma vs LED vs DLP is nearly the same for 3D video as for regular 2D video. I would suggest that you research and choose your 3D-TV set based on regular 2D TV viewing. However, if cost is a concern I recommend taking a close look at Mitsubishi's line of DLP 3D televisions.
In my opinion the Mitsubishi line of DLP 3D televisions give outstanding 3D performance and present an excellent value for new 3D shoppers. For example, compare these two models, both available at Amazon.com at the prices advertised on this date:

    Mitsubishi WD-60638     DLP         60-Inch 1080p 3D-TV    61 lbs. $998
    Panasonic TC-P58VT25 Plasma   58-Inch 1080p 3D-TV   142 lbs.  $3599 !

Another advantage of DLP TV's: DLP's are known to be as clear and bright after 10 years as on their first day. But DLP 3D-TV's have a disadvantage when it comes to 3D. DLP 3D-TV's use "3D-Ready" electronics as opposed to the newer "Full 3D".

TV has traditionally only been able to deliver a single image to a television screen. For all the innovation that we’ve seen in TV (including the move to colour, the migration to digital, and more recently, the launch of high definition services), all of these developments have only been able to work within the parameters of a single incoming TV feed - a 2D experience.

So even though HD delivers an intensity and richness which results in exceptional clarity and detail, it is still based on the same underlying picture delivery mechanism as previous TV formats.

3D TV is possible because of a series of major breakthroughs (principally in camera, post-production, encoding, set-top box and TV set technology) which means that domestic TVs are now capable of processing an image in a way that can deliver the depth information to the brain - much like the human eye - and hence add a further dimension to HD.
                                
For the first time, two images can now be merged and played out simultaneously on the same domestic TV display. Polarising glasses are currently used to help direct the correct left or right full colour on-screen image to the corresponding eye. The brain then processes each feed to create a single image, providing a level of depth and focus which means that the content is able to move to and from the foreground and therefore becomes three-dimensional.

3D TV SPECS

When the pictures started moving and talking, world was delighted. It had found a new source of entertainment – a bigger radio that had a nice picture screen along with audio – a black & white TV. But the dullness of black & white TV’s did not last for long. The real-world objects were much more vibrant and rich in color. They weren’t monotonous as the TV indicated. To offer an experience that was closer to real-life, colored TV’s followed soon. Even today the evolution of TV technologies hasn’t stopped. What started as a CRT television has undergone various remarkable enhancements in terms of display technologies, and the overall design. The most prominent types of TV’s that are still quite sought after around the world, even today, include: LCD TV, Projection TV, Plasma TV, Flat Screen TV, LED/OLED TV, and HDTV. But what next?
                               
So far we have been satisfied with 2D TV viewing. Television makers predict that the future belongs to 3D TV. Electronics majors Sony and Panasonic have announced that they plan to introduce 3D TV’s for 2010. The 3D video technology is already there but until recently it required viewers to use special glasses to experience the 3D effect. Clearly not many people would want to sit in their living rooms and stare at a TV screen through those funny plastic glasses. The latest technology eliminates the need of having glasses for 3D effect however using glasses will be a much cheaper option. With or without the special glasses, 3D video opens up new frontiers in the interactive TV. Not just the TV makers even the chip makers like Intel are positioning themselves for the future TV market.

3D picture viewing has already made to Digital Cameras. 3D Digital Cameras hit the headlines a few weeks ago and amazed us how the pictures could come alive in 3 dimensions. We can not only capture 3D pictures but can also get them printed on a special lamination to preserve the 3D effect. And of course, the captured pictures can be viewed in a special 3D picture display. Well, that was digital camera. Now the buzz is that 3D TV viewing is coming to our living rooms soon. 2010 may transform how we watch TV programs. Not only you'll enjoy characters jumping out of your TV screens, the technological advancements are all set to make TV a much more interactive device. Are you ready for 3D TV?
                         
Skeptics raise many doubts like having a 3D capable TV is not enough, it will required 3D content and who'll produce that and in what quantity. Well, those are valid concerns so are the potential data-transfer constraints. However, what's sure is that TV technology is prepared to take leap into the future.
