A proposed standard that recommends doubling the current 525 lines per picture to 1050 lines, and increasing the screen aspect ratio (that is, width to height) from the current 12:9 to 16:9, which creates a television screen shaped more like a movie screen.

a technological system that provides the highest quality television picture and sound.

An enhanced television system that provides about twice the vertical and horizontal resolution of existing NTSC television standards. The audio quality and video quality is comparable to compact disks and DVDs.

This is when a television signal is transmitted at a standard resolution that is far greater than the current standard.

One mode of operation of digital TV whereby the broadcaster transmits a wide-screen picture with many times more detail than is contained in current analog television pictures. HDTV has 1125 lines of resolution vs. NTSC signals which have 525 lines of resolution.

New viewing standard with an aspect ratio of 16:9/1.78:1. It is slated to have over 1000 lines of resolution, as well as to have Dolby Digital be the official sound format. There is an analog system in Japan, and a digital system proposed by the Grand Alliance for the US. This system is supposed to co-exist with the current standard and eventually replace NTSC around the year 2006.

The new digital broadcast standard designed to deliver significantly improved picture and sound quality, presented in a widescreen, movie-style format.

(HDTV): A television format that has more scan lines, resulting in higher resolutions, better color and enhanced sound.

This refers to the best picture available via digital television. In the U.S., the 1080i and 720p formats in a 16:9 aspect ratio are two typical HDTV formats. The 1080i format picture is composed of 1,080 alternately scanned horizontal lines. The 720p format picture is composed of 720 progressively scanned horizontal lines.

The current TV scenario, eg digital transmissions (which are expected to replace the old analogue transmissions in a few years), DVDs, wide screens and electronic file formats such as MPEG 4 and avi, taking more account of the human eye's ability to perceive differences in colour, intensity and refresh rate, etc.

A video system with approximately twice the horizontal and vertical resolution of conventional NTSC television, and presented in a 16:9 aspect ratio. See: NTSC, Aspect Ratio, Resolution

Generic term referring to a higher resolution format than previous standards. HDTV provides a wider image that more closely resembles a movie screen.

The generally agreed upon definition of HDTV is approximately twice the vertical and horizontal picture resolution of today's NTSC TV, which essentially makes the picture twice as sharp. HDTV also has a screen ratio of 16:9 as compared with most of today's TV screens, which have a screen ratio of 4:3. HDTV offers reduced motion artifacts (i.e. ghosting, dot crawl), and offers 5.1 independent channels of CD-quality stereo surround sound, (also referred to as AC-3).

Extremely high quality television signal with picture resolution nearly equal to that of film.

An improved television system which provides approximately twice the vertical and horizontal resolution of existing television standards. It also provides audio quality approaching that of compact discs.

Has an aspect ratio of 16:9, with basically twice the vertical and horizontal resolution of NTSC television, 4:3.

Television TTY

An innovative television format having approximately twice the number of scan lines in order to improve picture resolution and viewing quality.

A new standard of displaying and broadcasting television signals that uses at least twice the scan lines of normal television and a 16x9 aspect ratio,...

a form that provides crystal-clear quality wide-screen pictures with compact disc-quality surround sound. The aspect ratio of HDTV pictures is 16:9 as opposed to today's 4:3 format.

Abbreviated as HDTV, a recent form of broadcast of television signals in a significantly higher resolution providing images of superior quality. HDTV signals in the studios and arenas are normally carried over optical fibers due to the high bandwidths required for the digitized signal data.

3/4– An all-digital TV broadcast signal that delivers a high-resolution, wide-screen picture and 6 channels of digital sound. A resolution of 1,080 lines is considered high definition imagery, although 720 lines of progressive scanning has now come to be considered high resolution as well.

HDTV is a new television standard that uses digital signals rather than the current analog broadcast standard. HDTV signals contain over 700 horizontal lines of resolution, compared to the 525 lines of resolution that analog provides. HDTV is also geared toward a rectangular wide screen format (16:9) for a true theater-like experience. HDTV images are digitized and compressed before signal transmission to enable their tremendous quantity of information to pass through easily. The signals are then decompressed when they reach the television. From football to sitcoms, the result is a clear, crisp picture that brings every broadcast to life with more detail and truer color than any other picture format can offer.

(HDTV)- Digital television which offers twice the resolution, wider screens, better sound, and better color than the NTSC format. "True" HDTV involves a 16:9 aspect ratio and at least 720 lines per screen.

Offers approximately twice the vertical and horizontal resolution (clarity) of NTSC television. Provides crystal-clear quality widescreen pictures with compact disc-quality surround sound. The aspect ratio of HDTV pictures is 16:9, similar to a movie screen's dimensions, as opposed to the 4:3 format of today's television. HDTV duplicates movie theater display quality.

A digital television format that offers approximately twice the clarity of today's standard television. Provides crystal-clear, widescreen pictures with compact-disc-quality surround sound. HDTV duplicates movie theater display quality.()

An updated video format that provides approximately twice the horizontal and vertical resolution of NTSC, PAL or SECAM; and uses a 16:9 aspect ratio.

A digital-format system with higher resolution or pictorial clarity, as more lines per picture frame are transmitted.

An advanced television system that produces video images as clear as high quality photography.

A television signal with greater detail and fidelity than the current TV systems used. The USA currently uses a system called NTSC. HDTV provides a picture with twice the visual resolution as NTSC as well as CD-quality audio.

(HDTV) A television capable of displaying images at resolutions of 1,080-line interlaced (1080i) or 720-line progressive (720p).
