3D TV TECHNOLOGY, 3D TV SPECS, 3D TV FEATURES.

For the past 15 years, Philips has been at the forefront of 3D display technology. In that time, we have developed the expertise necessary to provide 3D quality both for specialized and mass-market applications. In this backgrounder, we will show you how 3D technology works and explain why the approaches of Philips 3D Solutions are particularly effective.
                                  
The next massive breakthrough in TV technology 3D has been demonstrated by Philips. The technology which will change the way TV is viewed will deliver a massive breakthrough for advertisers and movie makers.
3D is cool!
Having a night in with your friends? There is no better way of watching the latest movies, the coolest shows, and the most important sporting events, than in an exciting 3D mode!!

3D is going to be big!
There are great opportunities for consumers, as well as business and the professional market. Just imagine what 3D can do for the visualization of your product.

3D is the next big thing!
Hollywood is already shooting some big productions in 3D. They also know that soon, everybody will want to see their favorite movie in 3D!

Grab viewers attention and bring your content alive with WoWvx technology!
Imagine what Star Wars would like on a 3D screen! It’s like being there, in a Galaxy far far away yourself! And try to resist that freshly squeezed glass of orange juice springing out of the screen!

3D is based on the way the human brain and eyes work. Because the pupils of a person’s eye are about 6.5 cm apart, each eye views a scene from a different angle and generates a unique image. The brain merges the images to create a single picture. The slight difference between the image from the right eye and the image from the left eye allows the brain to judge the depth. Stereoscopic vision is attained.

Our ability to see in 3D is about perceiving depth. How far away things are from us. A combination of several components allow our brains to perceive our 3D world around us. Perspective is one, where things further away appear smaller. But that can sometimes trick us. Close one eye and look around you. You will immediately notice that the distance of the things around you is not so obvious. If you hold up two things in front of you and move one closer and further away, you will only be able to judge which is closer by their relative sizes. Some optical illusions rely on this by having smaller than usual objects closer to you, so creating the illusion of them being further away.

Another aspect of depth perception is focus. Look at your hand outstretched with a distant background. You will see your hand in focus but the background out of focus.
                
The final component of depth perception is only available to us because we have two eyes. Because our eyes are spaced apart, each eye sees a slightly different view. Our brain combines these two slightly different scenes and gives us a sense of how far away things are. A simple way to demonstrate that to yourself is to hold one finger up at arms length. Then close each eye in turn, and notice the position of your finger compared to the distant background. With your right eye open, your finger will appear to have moved to the left relative to the background.

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.
   

3D TV CHANNEL

After many years of hype 3D TV became a reality on 22nd April 2010 when John Lewis became the first UK retailer to sell 3D TV for the home. The rave reviewed Samsung C7000 is a 40" 3D Ready High Definition television that is available online and at the company's flagship Oxford Street store.
                         
The Samsung UE40C7000 is a superb 2D HD TV as well as being 3D Ready; At just 3cm thin the LED television offers full 1080p HD resolution, SRS Theatre Surround Sound and a built-in Freeview HD tuner.

Following on from the worldwide record-breaking success of 3d films like Avatar, the next generation of TV sets are almost here.

Armed with nothing more than a 3D television and a pair of 3D glasses, you could soon be experiencing the breathtaking realism of three dimensional movies in your own home. 3D TV is set to revolutionise home viewing the same way that colour screens changed black and white tv forever.

Companies that have so far announced plans to launch 3D TV include Sony, Panasonic, Samsung, LG, Toshiba and Mitsubishi. Hollywood studios including Disney and Dreamworks are already developing a number of 3D titles for both cinema and home use. Sky Television has also announced it will launch a 3D Tv channel in 2010.

“Well over a million homes have future-proofed themselves with Sky + HD, a platform for choice, quality and future innovation. With Sky + as standard, our customers are already enjoying amazing picture and sound quality on a range of high-quality HD channels which cater to the interests and passions of the whole family.

“Next year we will make our HD boxes work even harder for customers by launching Europe’s first 3D TV channel, as well as introducing a comprehensive video-on-demand service to complement Sky + and the current Sky Anytime service.

“3D is a genuinely ‘seeing is believing’ experience, making TV come to life as never before. Just like the launch of digital, Sky + and HD, this is latest step in our commitment to innovating for customers.”
                            
Sky launched the UK’s first national HD service in May 2006 which has since become Europe’s most successful HD service. Today Sky + HD customers can watch 33 HD channels from leading brands such as Sky Movies, Sky Sports, Channel 4, Disney, MTV, BBC, Discovery, FX, Sky1 and National Geographic. Sky + HD customers can choose up to 400 hours a day – or 13,000 hours a month – of quality HD content, which is significantly more than any other TV platform.

Further channels are due shortly, including ESPN HD (August 2009), and Sky News HD (Spring 2010), with a view to growing the offering to 50 channels over time.

Further details on Sky’s pull VOD and 3DTV services, including pricing, packaging and entitlement, will be announced closer to launch.

There will be no need for customers to upgrade their set-top boxes to access to the new 3D channel, as all existing Sky + HD boxes are already ‘3D Ready’. However, customers will need a new 3D Ready TV, which are expected to be on sale in the UK during 2010. More details on the channel, including timing, pricing and packaging will be provided in due course.

The human eye’s ability to see things with variable depth and wide perspective is based on how the brain processes two separate images, as received by each eye. When someone looks at something the brain is able to merge two separate images together to create a field of vision which is both three-dimensional and allows the viewer to focus on specific areas within any given scene.
