(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.
