MPEG 1
MPEG 1 :
(ICT) A video format. Short for "Motion Picture Experts Group". These are the people who were tasked with coming up with a new video standard. The problem with pure video data is that the files are truly huge - hundreds of gigabytes for a high quality hours'-worth of programme. So video is normally 'compressed' for storage or before being passed through a network. MPEG-4 is a 'lossy-compression' method which means a lot of the original data is thrown away - but the trick is to only throw away data in such a way that you do not notice a drop in video quality. This standard describes how the video is to be compressed and de-compressed. Video files compressed with this standard will have a file extension of .mpeg About 120 minutes of video, compressed with MPEG-4, can be stored on a DVD disk See also:
