Definition: 720p represents 1,280 pixels displayed across the screen horizontally and 720 pixels down the screen vertically. This arrangement yields 720 horizontal lines (pixel rows) on the screen, which are, in turn, displayed progressively, or each line displayed following another. This means that all 720 pixel rows are displayed at all times. Although 720p is high-definition, it takes up less bandwidth than 1080i or 1080p.
