Part 2: Video
Part 2 of the MPEG-1 standard covers video and is defined in ISO/IEC-11172-2. The design was heavily influenced by H.261.
MPEG-1 Video exploits perceptual compression methods to significantly reduce the data rate required by a video stream. It reduces or completely discards information in certain frequencies and areas of the picture that the human eye has limited ability to fully perceive. It also exploits temporal (over time) and spatial (across a picture) redundancy common in video to achieve better data compression than would be possible otherwise. (See: Video compression)

Famous quotes containing the words part and/or video:
“We are all androgynous, not only because we are all born of a woman impregnated by the seed of a man but because each of us, helplessly and forever, contains the other—male in female, female in male, white in black and black in white. We are a part of each other. Many of my countrymen appear to find this fact exceedingly inconvenient and even unfair, and so, very often, do I. But none of us can do anything about it.”
—James Baldwin (1924–1987)
“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)
