Replay

   Acorn Computers' full-motion video system written by Roger
   Wilson.  Video and sound information are stored in compressed
   form.  Compression is relatively slow but decompression is
   done in real-time with quality and frame-rate varying with
   the processing power available, the size of the picture and
   whether it appears in a window or uses the whole screen.
