From The Free On-line Dictionary of Computing (8 July 2008) [foldoc]:
video
<graphics> Moving images stored as a sequence of {static
images} (called "frames") representing snapshots of the scene,
taken at regularly spaced time intervals, e.g 50 frames per
second. Apart from the frame rate, other important properties
of a video are the resolution and colour depth of the
individual images.
Video data is typically stored and transmitted in a format
that includes synchoronised sound.
The many file formats in use for video differ chiefly in the
type of compression used. Compression is even more
important for video that for static images due to the large
amount of data involved in even a short video. Furthermore,
compression allows video to be transmitted via a channel whose
bandwidth is less than the raw data rate implied by the
resolution and frame rate. This allows the recipient to start
displaying the video before the transmission is complete, a
process known as streaming.
