	480p - Wikipedia, the free encyclopedia
		480p is the shorthand name for a video display resolution.
		The ATSC digital television standards define 480p with either 704x480 (non-square sampling) or 640x480 (square sampling) pixel resolutions, at 24, 30, or 60 Hertz frame rates.
		A 16:9 aspect ratio is defined at 720x480 pixels, using non-square, anamorphic sampling.

	Component video -- is 480p better than 480i?
		There is a lot of understandable confusion over component video, and whether progressive scan 480p output from a DVD player is better than interlaced output, 480i.
		Frequently, as you've probably heard, the 480p signal from the DVD player is better.
		Depending on the DVD player and projector that you have, you may or may not see a difference between 480p and 480i.
