High-definition video

From Fiswiki

A visual comparison of common TV display resolutions. A PAL image is made out of 720x576 non square pixels, NTSC is 720x486. However both have an aspect ratio of 4:3, leading to inaccuracies within this image. NTSC DV/DVD have only 480 active lines in order to accommodate compression pixel blocks.

High-definition video refers to any video system of higher resolution than standard-definition (SD) video, and most commonly involves display resolutions of 1280×720 pixels (720p) or 1920×1080 pixels (1080i/1080p).
