720p
720p is a high definition television resolution, and, in most cases, is the highest resolution in which HD content is broadcast under the ATSC standard, though some broadcasters (CBS, NBC, HBO, Showtime and Discovery HD) use the alternative, 1080i.
A 720p image is comprised of 720 vertical lines of video shown through progressive scan, meaning that every line is rendered from top to bottom in each screen refresh. By contrast, interlaced images (like 1080i) only render ever second line. 720p's pixel by pixel resolution 1280 x 720, and it's commonly displayed at refresh rates of 24, 25, 30, 50, and 60 Hz.
720p was initially designed by AT&T Bell Laboratories in the late 1980s. Most viewers consider it to be comparable in quality to 1080i, but lesser than 1080p.
