720p Terminology | Dictionary | Explanation 720p defines a resolution. The number 720 stands for 720 lines of vertical resolution, while the letter p stands for progressive scan or non-interlaced. 720p is considered to be an HDTV video mode. The term usually assumes a widescreen aspect ratio of 16:9, implying a horizontal resolution of 1280 dots across and a frame resolution of 1280 × 720 or about 0.92 million pixels. The frame rate in hertz can be either implied by the context or specified after the letter p (such as 720p30, meaning 30 frames per second). |
