    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

   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.
