      n 1: the visible part of a television transmission; "they could
           still receive the sound but the picture was gone" [syn:
           video, picture]
      2: a recording of both the visual and audible components
         (especially one containing a recording of a movie or
         television program) [syn: 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
         [syn: television, telecasting, TV, video]

From The Free On-line Dictionary of Computing (30 December 2018) :

      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.
