Computer generated graphic segments in a raster display

The increased use of computer graphics to enhance the man-machine interface has resulted in many and varied systems and devices to meet a multitude of needs. One type of display that is receiving new emphasis as a computer output device is the "raster format" display (of which standard television is a particular type). Among the reasons for using this type of display are: (1) the relative simplicity of the display device, (2) the ease of remote operation for multiple station users, (3) the low cost per station, (4) capability for mixing output with standard television sources, and (5) good position repeatability for computer generated data.
