Pixel aspect ratios for the scaling of various kinds of SDTV video lines Video format Display aspect ratio (DAR) Resolution Pixel aspect ratio (PAR) After horizontal scaling 480i: 4:3 704 × 480 (horizontal blanking cropped) 10:11 640 × 480: 720 × 480 (full frame) 655 × 480: 480i: 16:9 704 × 480 (horizontal blanking cropped) 40:33
The horizontal to vertical ratio of each pixel. Storage aspect ratio (SAR) The horizontal to vertical ratio of solely the number of pixels in each direction. [note 1] Display aspect ratio (DAR) The combination (which occurs by multiplication) of both the pixel aspect ratio and storage aspect ratio giving the aspect ratio as experienced by the ...
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 ...
In television technology, Active Format Description (AFD) is a standard set of codes that can be sent in the MPEG video stream or in the baseband SDI video signal that carries information about their aspect ratio and other active picture characteristics. [1]
Nominal analogue blanking is the outermost part of the overscan of a standard definition digital television image. It consists of a gap of black (or nearly black) pixels at the left and right sides, which correspond to the end and start of the horizontal blanking interval: the front porch at the right side (the end of a line, before the sync pulse), and the back porch at the left side (the ...

525-line (or EIA 525/60) is an American standard-definition television resolution used since July 1, 1941, [1] [2] [3] mainly in the context of analog TV broadcast systems. It consists of a 525-line raster , with 486 lines carrying the visible image at 30 (29.97 with color) interlaced frames per second.
In theory, television stations in the U.S. are free to choose any resolution, aspect ratio, and frame/field rate, within the limits of Main Profile @ High Level. Many stations do go outside the bounds of the ATSC specification by using other resolutions – for example, 352 x 480 or 720 x 480.
