(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?]
