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 ...
These may also use other aspect ratios by cropping otherwise black bars at the top and bottom which result from cinema aspect ratios greater than 16∶9, such as 1.85 or 2.35 through 2.40 (dubbed "Cinemascope", "21∶9" etc.), while the standard horizontal resolution, e.g. 1920 pixels, is usually kept.
16:9 is a widescreen aspect ratio with a width of 16 units and height of 9 units. Once seen as an "exotic" aspect ratio, [ 1 ] since 2009, it has become the most common aspect ratio for televisions and computer monitors , and is also the universal standard image format for the universal 1080p , 2160p and 4320p formats.
There are other, non-standard display resolutions with 1080 lines whose aspect ratios fall between the usual 16∶9 and the ultra-wide 64∶27, e.g. 18∶9, 18.5∶9, 19∶9 and 19.5∶9. They are mostly used in smartphones or phablets and do not have established names, but may be subsumed under the umbrella term ultra-wide (full) HD .
Since the same number of horizontal pixels are used in 4:3 and 16:9 broadcasts, the 16:9 mode is sometimes referred to as anamorphic widescreen. Most EDTV displays use square pixels, yielding a resolution of 852 × 480. However, since no broadcasts use this pixel count, such displays always scale anything they show.

The digitally transmitted horizontal resolution is usually 720 samples (which includes 16 samples for the horizontal sync and horizontal blanking) or 704 visible pixels with an aspect ratio of 4:3 (with vertically rectangular pixels) and therefore a display resolution of 640 × 480 ; that is standard-definition television (SDTV) with a 4:3 ...
Effectively 1/16 the total resolution (1/4 in each dimension) of "Full HD", but with the height aligned to an 8-pixel "macroblock" boundary.
