How Do Plasma Televisions Work?
Plasma TVs have been one of the most popular home entertainment solutions on the market for several years.
They offer outstanding resolution and a quality picture and are usually capable of displaying HDTV signals, allowing you to watch all of your favourite HDTV programs.
Compared to rear projection TVs, plasma technology offers some of the best viewing angles- no need to fight over the best seat anymore- and offer uniform screen brightness.
But how does plasma technology work?
It's pretty simple.
Some form of inert gas- say Xenon, for example, is inserted between two plates, which are held together, between which are over two million pixels, capable of producing a mind-boggling array of colors.
The gas is then energized by a charge which turns it into a viscous substance, creating an ultraviolet light, which allows each pixel to display the appropriate color.
Unlike rear-projection TVs, each pixel in a plasma display contains red, blue, and green phosphors, there is no need for a cathode-ray tube.
In traditional TVs, the cathode-ray tube, or CRT, fires electrodes to the screen, where they excite phosphor atoms causing them to light up, thus creating a picture.
The CRT
is bulky and is responsible for the box-shape of traditional televisions.
For example, if you want to increase the size of the screen in a CRT, you must also create a larger cathode-ray tube, therefore making the whole TV that much bigger- and bulky.
One drawback to plasma technology is the inability to recharge each individual pixel.
Each pixel is an independently sealed entity, as is the plasma display panel and the gas, so if a pixel, or a group of pixels, fail or darken, the entire panel unit must be replaced.
Fortunately, however, you can expect your plasma display to last at least 60,000 hours of playing time, before the pixels begin to darken.
So, in layman's terms, if you watch your TV for four hours a day, you can expect the panel to last around eighteen years.
Plasma technology has greatly increased the quality of home entertainment, ushering in a new era of television technology.

HD-DVD vs Blu-ray
High Definition DVD (HD-DVD) vs Blu-ray is shaping up to be a battle to rival the VHS vs Betamax format war of the early eighties. Looking like they've learned nothing from the DVD ? RW debacle, the companies involved, whether they are in the technology or content distribution industry (or in Sony's case, both), are set to slug it out over the next few years.The prize is the licence fees that will be payable to the format owners when the next generation of high definition DVD players and recorders start shipping in volume. As high definition television becomes increasingly popular, consumers will want a recordable format that has the capacity to hold at least a couple of hours worth of HDTV content. Both Blu-ray and HD-DVD were developed in response to the anticipated need for an HDTV recording medium and provide content whose quality would match the expectations of HDTV-owning customers. Additionally, the film distribution companies will cash-in as they release all the titles currently...

No World Record for HD Olympic Coverage, But the Race is On to Push HD Service to the Masses
Despite the fact that less than two million U.S. households actually received a high-definition feed of the summer Olympics ? with less than one million actually tuning into the HD programming ? this was the most extensive consumer exposure to HDTV programming and technology to date.
According to a new report from research consultancy The Diffusion Group, while HD Olympic coverage may have left many sophisticates complaining about limited selection and delayed programming, it nonetheless introduced the concept of high-definition television to a new and much more mainstream market.
However, exposure to HDTV is not the same as purchasing an HDTV or signing up for an HD service.
"One of the primary constraints to widespread HDTV diffusion is the widespread confusion among consumers as to what exactly HDTV is and does," says Scott Kipp, consulting analyst with The Diffusion Group.
"Although the critics of NBC's HD coverage are correct in many ways, there...
