A) General term for proposed standards pertaining to consumer high-resolution TV.
b) An ATV term sometimes confused with HDEP. HDTV is usually used to describe advanced production and delivery mechanisms that will get ATV to the home. As HDEP cannot practically be broadcast, all broadcast HDTV schemes must make compromises in quality. The line between broadcast HDTV and EDTV, therefore, is difficult to define. See Minimum Performance.
c) A TV format capable of displaying on a wider screen (16x9) as opposed to the conventional 4x3) and at higher resolution. Rather than a single HDTV standard, the FCC has approved several different standards, allowing broadcasters to choose which to use. This means new TV sets will have to support all of them. All of the systems will be broadcast as component digital. d) By HDTV, we normally understand transmission, rendering, and display systems that feature about double the number of scanning lines, improved colour quality, and less artefacts than that of today’s composite systems. The video may be analog, like the Japanese MUSE or the European HD-MAC, or digital, like the ATSC system in the USA. The European, MPEG-2 based Digital Video Broadcasting (DVB) specifications embrace HDTV in addition to 625-line TV.
In the USA, the Grand Alliance has succeeded in combining various digital HDTV systems into the ATSC system a multiple format system based on MPEG-2 video coding that allows HDTV transmissions to use the same frequency bands now used by regular NTSC television. The Japanese, who have had regular analogue HDTV transmission for some time, are also planning to implement digital HDTV.

A Sony trade name for its HDEP equipment and ancillary products, such as HD videodisc players.
Industry:Software
Recording of digital data on a magnetic medium, having a flux transition density in excess of 15,000 transitions per inch per track.
Industry:Software
Any magnetic oxide particle exhibiting a BSHC product higher than that of gamma ferric oxide. Chromium dioxide and cobalt are the two most common examples at the present time.
Industry:Software
Most commonly used to refer to the high quality audio tracks recorded by many VCRs. These tracks provide audio quality approaching that of a CD. However, because they are combined with the video signal before recording, audio dubs using them are impossible without re-recording the video.
Industry:Software
An information channel added to a television signal where the finest brightness detail is normally transmitted. As the human visual system is least sensitive to the finest detail, it is unlikely to be bothered by interface from such a subcarrier. This technique was first applied to the NTSC colour subcarrier; most recently it has been proposed in Toshiba’s ATV system.
Industry:Software
A range of allowed picture parameters defined by the MPEG- 2 video coding specification which corresponds to high-definition television.
Industry:Software
A) Any increase or decrease in strength of an electrical signal. Gain is measured in terms of decibels or number of times of magnification.
b) The ratio of output power to the input power for a system or component.
c) The amount of amplification of a circuit. The term gain is often used incorrectly to denote volume and loudness which are psychological factors which are the results of “gain.” Gain Ratio Error
