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.
HDTV resolutions
The HDTV standard defines display resolutions of:
- 1080i (1,080 lines of pixels in an interlaced configuration)
- 720p (720 lines, progressive)
- 1080p (1080 lines displayed progressively)
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.
1080p technically falls into the category of FHD (Full High Definition), not HD like 720p and 1080i. But, a television with this resolution is still called an HDTV.
The cutoff date for the last analog signal to transmit was June 12, 2009. After that, all broadcasts moved to digital high-definition in the United States.
