3D and HD Television Update - 3D Without Glasses

May 23, 2008 | Chris Payatagool

Each frame a 35-megapixel photo: JVC develops next-gen Super Hi-Vision

1080p high definition might be well and good for your average lounge room TV screen, but cinema projectors need to offer something vastly more impressive if the movies are going to continue to offer a bigger, clearer and more impressive viewing experience than your average cashed-up punter can now get at home. The new ultra-high res standard would now appear to be set with Super Hi-Vision: 7,680 pixels across by 4,320 pixels high (approximately 32-megapixel images) - and JVC have now released a video projector capable of showing 35 megapixels at once. The 8K4K JVC D-ILA (Direct-Drive Image Light Amplifier) has a resolution more than 17 times the level of standard HDTV, and is now the highest-resolution projection display device on the planet.

The meteoric rise of 1080p high-definition as the standard for home TV sets has made it clear to manufacturers that even the average family is willing to spend previously unheard-of amounts of money to put high quality video displays in the lounge room. But when everybody has HDTV, where do you go for the next level up?

When Super Hi-Vision was launched at NAB2006, there was huge consumer interest in this new format with 16 times the resolution of HD; with each frame the equivalent of a 32-megapixel photo, even large presentations could be completely immersive. It's worth remembering that HD itself is only a little over 20 years old, and when it made its debut in the 1980s there was little in the way of transmission or data storage to make it a practical home device. The situation is similar for us today looking at the Super Hi-Vision format; we don't have the bandwidth or the storage media to play movies at 16 times the current definition - but we will, soon enough.

One thing we do now have is the projection technology to output Super Hi-Vision, with JVC's recent announcement that it has managed to cram 35 megapixels of resolution into a 1.75-inch DILA projection device. This is the highest resolution ever offered by a projection device, and it also offers an excellent 20,000:1 contrast ratio.

JVC clearly sees the "beyond HD" market as a high growth area, not just for digital cinema, but in presentations, monitoring and medical applications as well. And yes, there are apparently proposals underway to make Super Hi-Vision a future TV broadcasting standard. So start saving for your next home cinema upgrade, because it's going to be a whopper!

Philips demonstrates products in the pipeline including "3D TV" without glasses

Even before we get used to high-definition TV, researchers are planning to place "3D" TV in our homes - but without the funny glasses.

Philips Electronics NV gave a peek into its research pipeline Tuesday, demonstrating a prototype that was still fuzzy around the edges. Operating like a holographic greeting card, it combines slightly different angles of the same image to create video that appears to have different depths as your eyes scan it.

The result is uneven, at some moments blurry, and at others merely two dimensional. But sometimes the apparent depth or protrusion can be startling.

"We say the market progression is black and white, to color, to high definition, to 3D," said Bjorn Teuwsen, demonstrating the product. "We estimate in a few years these will be in homes."

Specialized models have been sold to corporations - mostly movie theaters and casinos - where they are usually used for advertising signs, since 2006. But Philips said the product is not yet ready for consumer rollout.

Samsung is demonstrating its own no-glasses 3D television concept model this week in Las Vegas.

Philips' 3D television is one of several products shown to reporters Tuesday, ranging from space-age lighting for shop windows to energy efficient water purifiers intended for the developing world.

The company has sold more than 2 million televisions with "ambient" backlighting to heighten mood effects. The company's vice president for research, Fred Boekhorst, said Tuesday that Philips plans similar features that would involve "other senses."

Such as smell-o-vision? A TV that reaches out and punches you in the nose? Boekhorst wouldn't say, other than that it would "involve emotions."

"What next step could you take in the area of relaxation and emotion?" he said, in answer to questions.

Philips showed off lighting products in early stages of development on Tuesday, including one using light-emitting diodes that is transparent like ordinary glass until it is turned on - and then its entire surface turns into a light.

"You can imagine a lot of uses for this, for instance being used in an office wall to create an instant private space," said researcher Coen Verscheuren.

For emerging markets, Philips has developed a water purification system based on ultraviolet light, which fries away organic material such as bacteria. It is quicker and uses less energy than boiling water, said researcher Georg Greuel.

Other companies also are using ultraviolet light for water purification. Philips claims its next generation will be capable of cleaning 6 liters (1.6 gallons) of water per minute, using 30 watts of electricity.

Philips already has introduced a household model in India, but the technology could also be used for bottle-sized versions for individuals, and in larger installations for cities.
