1080p(1920 × 1080 progressivelydisplayed pixels; also known as Full HDor FHD, and BT.709) is a set of HDTVhigh-definition videomodes characterized by 1,920 pixels displayed across the screen horizontally and 1,080 pixels down the screen vertically;[1]the pstands for progressive scan, i.e.non-interlaced.
The extra pixels are used to form the increased area to the sides of the D1 image. The pixel density of 960H is identical to standard D1 resolution so it does not give any improvement in image quality, merely a wider aspect ratio. Alternative analog video transport technologies carrying higher resolutions than 960H include HD-TVI, HDCVI, and AHD.
720p (720 lines progressive) is a progressive HD signal format with 720 horizontal lines/1280 columns and an aspect ratio (AR) of 16:9, normally known as widescreen HD (1.78:1). All major HD broadcasting standards (such as SMPTE 292M) include a 720p format, which has a resolution of 1280×720p. The number 720 stands for the 720 horizontal scan ...
1440p is a family of video display resolutions that have a vertical resolution of 1440 pixels. The p stands for progressive scan, i.e. non- interlaced. The 1440 pixel vertical resolution is double the vertical resolution of 720p, and one-third (about 33.3%) more than 1080p. QHD ( Quad HD) or WQHD ( Wide Quad HD) is the designation for a ...
1920 × 1080 (FHD) FHD ( Full HD) is the resolution 1920 × 1080 used by the 1080p and 1080i HDTV video formats. It has a 16:9 aspect ratio and 2,073,600 total pixels, i.e. very close to 2 megapixels, and is exactly 50% larger than 720p HD ( 1280 × 720) in each dimension for a total of 2.25 times as many pixels.
480p is the shorthand name for a family of video display resolutions.The p stands for progressive scan, i.e. non-interlaced.The 480 denotes a vertical resolution of 480 pixels, usually with a horizontal resolution of 640 pixels and 4:3 aspect ratio (480 × 4 ⁄ 3 = 640) or a horizontal resolution of 854 (848 should be used for mod16 compatibility) [1] pixels for an approximate 16:9 aspect ...
1080p progressive scan HDTV, which uses a 16:9 ratio. Some commentators also use display resolution to indicate a range of input formats that the display's input electronics will accept and often include formats greater than the screen's native grid size even though they have to be down-scaled to match the screen's parameters (e.g. accepting a 1920 × 1080 input on a display with a native 1366 ...
Pixel aspect ratio values for common standard-definition video formats are listed below. Note that for PAL video formats, two different types of pixel aspect ratio values are listed: Rec.601, a Rec.601-compliant value, which is considered the real pixel aspect ratio of standard-definition video of that type.
