full-motion video
     
        (FMV) Any system used to deliver moving video images and sound
        on a computer.  Video images and sound are stored on disk;
        {compact disc} is preferred because of the amount of data
        required.  Some form of {video compression} is used to reduce
        the amount of data and to allow it to be read from disk
        quickly enough.  Compression can be relatively slow but
        decompression is done in {real-time} with the picture 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.
     
        {Acorn Computers}' system is called {Replay} and {Apple
        Computer}'s is {QuickTime}.
     
        Compare {MPEG}, {H.261}.
     
        [IBM PC equivalent?  Do they all use compression?  Web page?]
