High-definition video is video of higher resolution than is standard. While there is no specific meaning for high-definition, generally any video image with more than 480 horizontal lines (North America) or 570 lines (Europe) is considered high-definition. 720 scan lines is generally the minimum even though many systems greatly exceed that. Images of standard resolution captured at rates faster than normal (60 frames/second North America, 50 fps Europe), by a high-speed camera may be considered high-definition in some contexts. Additionally, non-interlaced video (also called progressive scan) is sometimes considered high resolution, even at standard resolution and frame rates.

Famous quotes containing the word video:
“These people figured video was the Lords preferred means of communicating, the screen itself a kind of perpetually burning bush. Hes in the de-tails, Sublett had said once. You gotta watch for Him close.”
—William Gibson (b. 1948)
