high-definition television

high-definition television
a) General term for standards pertaining to consumer high-resolution TV. b) A TV format capable of displaying on a wider screen (16:9) as opposed to the conventional 4:3) 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. c) By HDTV, we normally understand transmission, rendering and display systems that feature about double the number of scanning lines, improved color quality, and less artifacts than that of composite systems.[1]
