MEPG视频压缩是一种启动技术,能为用户提供大量新产品,如能存储数小时电影的音乐光盘(5寸/12厘米)和同时能向各个家庭传送几百路电视的直接卫星电视。 为何需要压缩 数字式视频信号需要“压缩”,原因是一幅标准的电视画面需要大量的数据--大约每秒2亿位(bit)的数据
MEPG Video Compression is a start-up technology that offers users plenty of new products such as music discs (5 “/ 12 cm) that store hours of movies and direct satellite TV that can simultaneously deliver hundreds of channels of television to homes. Why compressing digital video signals requires ”compression," because a standard TV picture requires a lot of data - about 200 million bits per second
