720p refers to a progressive HDTV signal with 720 horizontal lines and an aspect ratio (AR) of 16:9 (1.78:1). All major high definition (HD) TV broadcasting standards include a 720p format which has a resolution of 1280×720, however there are other formats, including HDV and AVCHD for camcorders, which utilize 720p images with the standard HDTV resolution. The number 720 stands for the 720 horizontal scan lines of image display resolution (also known as 720 pixels of vertical resolution), while the letter p stands for progressive scan (i.e. non-interlaced). When broadcast at 60 frames per second, 720p features the highest temporal (motion) resolution possible under the ATSC and DVB standards.

720i (720 lines interlaced) is an erroneous term found in numerous sources and publications. Typically, it is a typographical error in which the author is referring to the 720p HDTV format. However, in some cases it is incorrectly presented as an actual alternative format to 720p. In fact, no proposed or existing broadcast standard permits 720 interlaced lines in a video frame at any frame rate. 720i can also refer to technology in which only half the lines are shown each scan.
