HDTV is a set of video quality standards which include resolutions far better than normal NTSC or PAL TV. The most common resolutions discussed are 1080i (1080 horizontal lines of resolution) and 720p (720 lines). The ‘i’ stands for interlaced and the ‘p’ stands for progressive.

Standard NTSC signals (regular TV) have 525 lines of resolution, of which only 480-483 are visible. NTSC video is commonly called ‘480i’.
