MPEG-3
     
         A proposed
        variant of the {MPEG} {video} and {audio} {compression}
        {algorithm} and {file} format.  MPEG-3 was intended as an
        extension of {MPEG-2} to cater for {HDTV} but was eventually
        merged into MPEG-2.
     
        Not to be confused with MP3 - {MPEG-1 layer 3}.
