Term Definition

16:9 (Pronounced "Sixteen by Nine") Aspect ratio of 16 units wide and 9 units high. HDTV has an aspect ratio of 16:9.
1080p (Pronounced "Ten-Eighty-P") 1080p is the shorthand identification for a format of HDTV video modes. The number 1080 represents 1,080 lines of vertical resolution (1,080 horizontal scan lines), while the letter p stands for progressive scan (meaning the image is not interlaced). The term usually assumes a widescreen aspect ratio of 16:9, implying a horizontal resolution of 1920 pixels. This creates a frame resolution of 1920×1080. The frame rate can be either implied by the context or specified after the letter p (or i), such as 1080p30, meaning 30 progressive frames per second, or 1080i60, meaning 60 interlaced fields per second.
1080i (Pronounced "Ten-Eighty-I") 1080i is the shorthand name for a format of high-definition video modes. 1080 denotes the number of horizontal scan lines—also known as vertical resolution—and the letter i stands for interlaced. In the alternate format of high-definition video mode, known as 1080p, the p would stand for progressive scan. The term usually assumes a widescreen aspect ratio of 16:9, implying a horizontal resolution of 1920 pixels and a frame resolution of 1920×1080 or about 2.07 million pixels.
