  MPEG-1
  
     <compression, standard, algorithm, file format> The first
     MPEG format for compressed video, optimised for CD-ROM.
     MPEG-1 was designed for the transmission rates of about 1.5
     Mbps achievable with Video-CD and CD-i.
  
     It uses discrete cosine transform (DCT) and Huffman coding
     to remove spatially redundant data within a frame and
     block-based motion compensated prediction (MCP) to remove
     data which is temporally redundant between frames.  Audio is
     compressed using subband encoding.  These algorithms allow
     better than VHS quality video and almost CD quality audio to
     be compressed onto and streamed off a single speed (1x)
     CD-ROM drive.
  
     MPEG encoding can introduce blockiness, colour bleed and
     shimmering effects on video and lack of detail and
     quantisation effects on audio.
  
     The official name of MPEG-1 is International Standard
     IS-11172.
