HDTV the visual wonder...!!!

High-definition television (HDTV) is a digital television broadcasting system with a significantly higher resolution than traditional formats (NTSC, SECAM, PAL). While some early analog HDTV formats were broadcast in Europe and Japan, HDTV is usually broadcast digitally, because digital television (DTV) broadcasting requires much less bandwidth. HDTV technology was first introduced in the US during the 1990s by a group of electronics companies called the Digital HDTV Grand Alliance.

High-Definition television was first developed by Nippon Hōsō Kyōkai, and was unveiled in 1969
Though the system did not become mainstream until the late 1990s.
In the early 2000s, a number of high-definition television standards were competing for the still-developing niche markets.
Current HDTV standards are defined by the International Telecommunication Union (ITU-R BT.709) as 1080 active interlace or progressive scan lines, or 720 progressive scan lines, using a 16:9 aspect ratio. All current HDTV broadcasting standards are encompassed within the DVB specification.
HDTV is also capable of "theater-quality" audio because it uses the Dolby Digital (AC-3) format to support "5.1" surround sound. It should be noted that while HDTV is more like a theater in quality than conventional television, 35mm and 70mm film projectors used in theaters still have the highest resolution and best viewing quality on very large screens. Many HDTV programs are produced from movies on film as well as content shot in HD video.
The term "high-definition" can refer to the resolution specifications themselves, or more loosely to media capable of similar sharpness, such as photographic film. As of 2007, 24 million US households have HDTVs. However, only half are set up to actually receive HDTV programming as some consumers are not aware that they must get special receivers to get HDTV from cable, or use HDTV tuners to receive over-the-air broadcasts, and some are planning to use it in the future.

SONY BRAVIA The class apart...!!!!

BRAVIA is a Sony brand used to market its high-definition LCD televisions. The name is an acronym of "Best Resolution Audio Visual Integrated Architecture". All new Sony high-definition flat-panel LCD televisions in North America now carry the BRAVIA logo.
The name BRAVIA replaces the "LCD WEGA" brand name which Sony LCD TVs used up until Summer 2005 (early promotional photos exist of the first BRAVIA TVs still bearing the WEGA name).

Like other high definition television lines the various Bravia models differ in capability as well as screen size. Display capability depends on which high definition outputs are supported, and the input signal supplied to the television. Bravia televisions can display video from a variety of sources. The quality of the picture depends on the quality of the input.
The coax connector can receive regular television broadcasts, cable, and VCR/DVD output and will also receive and decode whatever high definition content is available on broadcast or cable television. Most high definition television which is broadcast is in the lower resolution high-definition formats.
Other traditional VCR/DVD outputs such as S-Video or Component video deliver the traditional television resolution that is no better than the resolution displayed by traditional television.
The HDMI input delivers the highest quality signal to the television and produces the highest quality high definition television picture, to the limits of the capabilities of the television. However, all HDMI has the HDCP content protection system built-in and this will degrade resolution of the display should the HDCP detect the presence of an unauthorized device. This limits the devices which deliver high definition TV content to those which are unable to record or otherwise duplicate protected content.
A VGA style computer connection is available, however the resolution of the video signal received from a computer may be limited to resolutions below the capability of the television depending on the capabilities of the computer's graphics card.
Purists will want to adjust the display on installation. The default configuration artificially enhances the color and contrast of the image to produce a more eye-catching, "vivid", display. This is easily done via a menu selection.
