Definition: Moving Picture Experts Group: digital standards for video and sounds including compression standards and file structure consisting of layers carrying video data in a hierarchical form. * Do not confuse with Motion JPEG. It all sounds the same to me The Internet music format is called MP3, which is short for MPEG-2 Layer 3: which, just to confuse things, is not a motion picture standard at all. It is audio only (maybe why it is also called MPEG-2 Audio). It compresses audio files by as much as 12 times with quality loss being evident only to golden-eared audiophiles (the main consumers of MP3 are half-deafened already).
