video
n 1: the visible part of a television transmission; "they could
still receive the sound but the picture was gone" [synonym:
{video}, {picture}]
2: a recording of both the visual and audible components
(especially one containing a recording of a movie or
television program) [synonym: {video recording}, {video}]
3: (computer science) the appearance of text and graphics on a
video display
4: broadcasting visual images of stationary or moving objects;
"she is a star of screen and video"; "Television is a medium
because it is neither rare nor well done" - Ernie Kovacs
[synonym: {television}, {telecasting}, {TV}, {video}]

Moving images presented 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.

Digital video data is typically stored and transmitted in a
format like {MPEG} or {H.264} that includes synchoronised
{sound}.

Unlike broadcast {television}, digital video on a computer or
network uses {compression}. 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}.

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 and the size and
scaling of the picture.

There are many types of software for displaying video on
computers including {Windows Media Player} from {Microsoft},
{QuickTime} from {Apple Computer}, {DivX}, {VLC}, {RealPlayer}
and {Acorn Computers}' {Replay}.
