Comparison To Other Video Formats
Below is a list of modern, digital-style resolutions (and traditional analog "TV lines per picture height" measurements) for various media. The list only includes popular formats. All values are approximate NTSC resolutions. For PAL systems, replace "480" with "576".

Famous quotes containing the words comparison to, comparison and/or video:
“In comparison to the French Revolution, the American Revolution has come to seem a parochial and rather dull event. This, despite the fact that the American Revolution was successful—realizing the purposes of the revolutionaries and establishing a durable political regime—while the French Revolution was a resounding failure, devouring its own children and leading to an imperial despotism, followed by an eventual restoration of the monarchy.”
—Irving Kristol (b. 1920)
“What is man in nature? A nothing in comparison with the infinite, an all in comparison with the nothing—a mean between nothing and everything.”
—Blaise Pascal (1623–1662)
“These people figured video was the Lord’s preferred means of communicating, the screen itself a kind of perpetually burning bush. “He’s in the de-tails,” Sublett had said once. “You gotta watch for Him close.””
—William Gibson (b. 1948)
