A Guide To Plasma Televisions

One of the newest additions in television technology, Plasma Televisions are the 21st century display devices which are fast becoming a popular choice among television viewers. Plasma televisions have higher resolution and quality performance than other conventional televisions; they guarantee crisp and clear images, and superior quality.

Plasma televisions became a reality after the successful invention of the plasma display panel in 1964, by Donald L. Bitzer and H. Gene Slottow at the University of Illinois at Urbana-Champaign. Embracing a unique technology, Plasma televisions produce pictures from a combination of inert gases such as xenon and neon. When the gas is charged using electrodes, the atoms collide with each other and release energy in the form of invisible ultra violet (UV) light. The light is then focused on the three phosphors (red, green, and blue) and a brilliant picture is produced.

Plasma televisions come as Enhanced Definition TV (EDTV) with a resolution of 852x480 and the Higher Definition TV (HDTV) featuring a native resolution of 1024x768. Plasma televisions have a high widescreen aspect ratio - the ratio between the width and height of the screen. As plasma televisions do not use any electron beams like the conventional ones, they are immune to the effects of magnetic fields. They offer a wider viewing angle and accurate image reproduction. Plasma televisions are slim and space-saving and can even be hung on a wall. Moreover, most of the plasma televisions come with a flat screen which eliminates edge distortion.

Plasma televisions can be used in meeting rooms, corporate offices, and network control rooms. They are ideal choices for home-theater enthusiasts. On account of quality performance in ambient light, plasma televisions are widely opted for teleconferencing.

A countless number of retail and online stores specialize in plasma television sale. Due to their inherent merits, plasma televisions are becoming the most demanded alternative to the standard CRT and projection televisions.

A plasma television console can be a more forgiving piece of furniture to have in your living room if you have a lot clutter that you need to hide, such as a gaming console, a ton of movies, a DVD player and maybe a stereo system. It’s just not feasible to have one of those cute shelf-like systems that will display your clutter and make your hot streamline television look like the flag atop a pile of rubble.

A plasma television console comes is in wood or a nice metal finish would be the perfect addition to set off your new TV set. This type of set up offers a wide area to display your new Plasma and plenty of storage space underneath for your video game console and DVD player. This is a popular choice among owners because it has a contemporary feel to it that still follows suit with the sleek design of the plasma.

There are wider versions of the credenza style and narrower ones that are just wide enough to cover the width of your new TV. This variety gives you ample flexibility no matter how large or small a space you have available. Not everyone can pull of the look of a strategically wall mounted television set; we need the furniture!

A new plasma television console will open up the area you are show casing, making an otherwise cramped space seem inviting and comfortable. Especially when you’re used to having a huge “entertainment system” taking up an entire wall of your living room, going to a wall mount can be too much of a culture shock.

The stream line look of the plasma TV and the plasma television console are the contemporary design that everyone is going for these days. The idea of “classic furniture” now even has a taste of contemporary mixed in. The plasma television console is a nice transition piece even for those that still have a more classic air to their homes. It will blend the two styles perfectly.

These devices give the illusion of streamline cleanliness, making your room give off a more professional feeling. Over all, there are a lot of choices similar to the ever familiar “entertainment center” out there to accompany your new purchase, it’s just a matter of knowing what suits your style.

HDTV - High Definition Television

Television, one of the greatest entertainment devices ever created.

Back in the day, people were outstanded by the capability of being able to watch broadcasts in black & white.

People were amazed by the technology of being able to watch live broadcasts from across the world, films and sports all whilst not having to leave their homes.

Then came along colour!

Obviously, we have come a long way since then, what with the capabilities of computers and the internet, video calling and other technological advances, having colour television all seems a bit primitive.

Since colour television there also have been some more advances for our viewing pleasure.

There was the VCR, giving people the choice of recording their programmes or buying video’s for their kids.

Then came along DVD. DVD produced improved quality in audio and visual a normal VCR cassette couldn’t compete with, as well as separating the films into scenes and sections, and adding extras.

Now with digital television widely becoming the standard, we have LCD (Liquid Crystal Display) & Plasma screens, again improving picture quality whilst saving space. But it doesn’t stop there.

The new technology that again, will improve the viewing pleasure is ‘High Definition TV’ or HDTV for short.

So, what is HDTV?

HDTV is the latest generation of digital TV, providing life-like picture quality, at least four times superior to current standards. It will provide extremely clear and fine picture detail with richer colours, improving the visual experience.

At launch, HDTV is thought to be available from BSkyB. In order to view programmes broadcast in 'High Definition', a soon to be released HDTV Sky Receiver with Sky+ technology will be required. In addition, the benefit of High Definition will only be apparent through a HDTV television (ideally plasma or LCD).

Please note, not all Plasma & LCD televisions currently available are HDTV compatible. It is expected to become available in the first quarter of 2006.

HDTV – The High Resolution Television

The expansion of hdtv is High-definition television. The hdtv means television signals broadcast with a higher resolution than traditional formats like NTSC, SÉCAM, PAL. The hdtv is broadcasted digitally, except for early analog formats in Europe and Japan.

Historically, the term high-definition television was also used to refer to television standards developed in the 1930s to replace the early experimental systems, although, not so long afterwards, Philo T. Farnsworth, John Logie Baird and Vladimir Zworkin had each developed competing TV systems but resolution was not the issue that separated their substantially different technologies. It was patent interference lawsuits and deployment issues given the tumultuous financial climate of the late 20's and 30's. Most patents were expiring by the end of WW2 leaving the market wide open and no worldwide standard for television agreed upon. The world used analog PAL, NTSC, SECAM and other standards for over half a century.

The terms HD ready and HD compatible are being used around the industrial world for marketing purposes. They indicate that a TV or display is able to accept video over an HDMI connection, using a new connector design, the main purpose of which seems to be to ensure that digital video is only passed over an interface which, by agreement, incorporates copyright protection. Even HD-ready sets do not necessarily have enough pixels to display video to the 1080-line (1920x1080) or 720-line (1280x720) HD standards in full resolution without interpolation, and HD-compatible sets are often just standard-definition sets with an HDMI input. This is a confusing use of the terms HD and hdtv.

MPEG-2 is most commonly used as the compression codec for digital hdtv broadcasts. The hdtv is capable of "theater quality" audio because it uses the Dolby Digital (AC-3) format to support "5.1" surround sound.

Japan has the earliest working hdtv system still in use, with design efforts going back to 1979. Japan began broadcasting analog hdtv signals in the early 1990s using an interlaced resolution of 1035 lines (1035i). The Japanese MUSE (Multiple sub-nyquist sampling Encoding) system, developed by NHK Science and Technical Research Laboratories (STRL) in the 1980s, employed filtering tricks to reduce the original source signal to decrease bandwidth utilization.

Japan is forerunner of hdtv in the world. Japan terrestrial broadcast of HD via ISDB-T started in December 2003.

The hdtv transmission in Europe started in 2004. Euro1080 is the pioneer in hdtv transmission in Europe. Australia started HD broadcasting in January 2001.

CHUM Limited's Citytv in Toronto was the first hdtv broadcaster in Canada and CBC (Canadian Broadcasting Corporation) officially launched hdtv programming on March 5, 2005.

Mexican Television company Televisa experimented hdtv broadcasts in the early 1990s, in collaboration with Japan's NHK.

The hdtv specifications are defined by the ATSC in the United States. An hdtv-compatible TV usually uses a 16:9 aspect ratio display with an integrated ATSC tuner. Lower resolution sources like regular DVDs may be upscaled to the native resolution of the TV.

The hdtv services were made available in the Republic of Korea in 2005 and Brazil is expected to go for it in 2006.

There are numerous online sources carrying volumes of info on plasma hdtv, lcd hdtv, hdtv antenna, hdtv receiver, dlp hdtv, hdtv cables, hdtv tuner etc. Scores of sites are offering hdtv reviews, hdtv articles and hdtv news that are very helpful for the potential customers to buy hdtv.

The Samsung 42 Plasma -- Samsung HP-P4271 42in HDTV Ready Plasma Television

The new fourth-generation Samsung 42 plasma is out, offering state-of-the-art high performance high-definition display and resolution.

As opposed to the liquid crystal type display technology, plasmas create their stunningly life-like pictures through a complicated gas-based system. The plasma display idea has been around since 1964, but is only now coming into its own for practicality.

At a slim and trim 3.4 inches in depth, the flat-screened plasma takes up virtually no space in your room, making it the screen of choice for both home and office. This plasma's high-end display resolution of 1024 x 768 pixels gives a picture quality and depth of color that are outstanding.

The Samsung plasma television screen under discussion is 42 inches, measured diagonally. Plasmas range in sizes from 32" up to the gigantic 63" screen. A 42" plasma screen is best viewed from ten to fourteen feet away, and has a high-end 160 degree viewing angle that is completely uniform, due to its perfectly flat screen.

The "Virtual Surround" audio system for this Samsung plasma TV simulates multiple-channel surround sound using fewer speakers. It has SAP/MTS stereo which enables three-channel audio encoding, an audio leveler which evens out sudden volume changes such as commercials, and Secondary Audio Programming (SAP) which allows reception of more than one soundtrack simultaneously.

Samsung plasma televisions are built from scratch in the factory. The HP-P4271 has almost twice as many pixels as EDTV plasmas, resulting in a clearer, sharper image. A great investment in your home entertainment center.

The History of the Television to Today’s Plasma TV

For the average person, even a regular television set is something of a technological marvel that becomes almost unbelievable when considering today’s latest and greatest advances, including the plasma TV. Take a brief look at the history of the technology that we now take for granted.

As early as the 1950s, people were beginning to have television sets in their homes, though the practice of a home television set wouldn’t become widespread until the 1960s. Suddenly, the average person could be a bystander for historic events, catch the latest news and spend hours being entertained.

In those early days of television, an analog signal transmitted the audio and video that would become a picture on the home television set. The early home sets used a tube technology – it took ages to warm up sufficiently to produce a picture. The analog signal was prone to fuzzy pictures that could fade out completely with various conditions. A home typically had an antenna, either on top of the television set itself or standing outside the house. Adjusting that antenna could help the reception of the picture.

Many things have changed since those early days of television. Analog signals are still used, though high definition digital signals are becoming more common.

Remarkably, there have always been experiments and advances in the works, many appearing on the drawing boards long before they’re introduced to the public. In the case of plasma TVs, the idea has been around almost as long as the video technology. The first plasma screen was actually constructed by a college professor and his student as early as 1964. The idea was sound, but the high-end television set simply wasn’t practical for the signal technology of the day. After all, there was little need for a screen that could produce a better picture than the television stations could send!

The reason for that early development wasn’t aimed at the television industry, but was to be used for displaying information in an educational setting. When the television industry started looking at newer, better technology for the tube-type television sets commonly being used in the 1960s, plasma was actually considered, though only briefly. In the end, the more practical idea became the liquid display screen television screens and it would be many more years before the plasma TV option was again considered.
