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 AppleComputer's is QuickTime.

Compare MPEG, H.261.

[IBM PC equivalent? Do they all use compression? Web page?]
