Short for high-definition television, HDTV is a generation of television first approved by ATSC on December 24, 1996, that offers higher resolutions and clarity.
The HDTV standard defines display resolutions of:
- 1080i (1,080 lines of pixels in an interlaced configuration)
- 1080p (1,080 lines of pixels displayed progressively)
- 720p (720 lines, progressive)
HDTVs are displayed on a wider screen because of the 16:9 aspect ratio although not all wide screen displays are capable of displaying HD. The picture is an example image of a 1080p HDTV, the Panasonic TH-58PZ750U.
