isr.co.ro : glossary MPEG (Moving Pictures Experts Group) A standard for compressing and decompressing video and other moving images. The MPEG standard allows for slight losses in what should be unimportant picture detail in return for smaller compressed file sizes and faster processing. In addition, this method calls for the removal of any "redundant" information that's repeated in successive frames. Technically, it provides both "intraframe" and "interframe" compression. However, even at small image sizes and typical compression factors of more than 20, MPEG files representing video images usually require from hundreds of kilobits to many megabits of information per second. That means you typically let an MPEG file download for many minutes or even hours, and then get to see a few seconds of tiny video. The industry committee that developed the standard.
