Figure  14-16.—Character  generator  (CG). You can limit details to the essential areas by using Some of the more advanced CGs feature 14 to 16 simplified   drawings.   For   example,   if   you   want   to emphasize the state of Colorado on a map of the United States, you could retrace the borders and darken the state area with green or blue tints. Keep written copy on charts to a minimum. Maxi- mum  clarity  with  minimum  essentials  must  be  your chief  objective. Character Generator When you have a lot of printed information to air, such as sports scores or closing credits, you should use a  character  generator  (CG)  (fig.  14-16).  The  CG  is  a computer graphics system used widely in closed circuit and broadcast television. It creates letters and numbers in a variety of sizes and fonts and requires no special skill for the user to make flawless letters. A   CG   has   a   solid-state   keyboard   similar   in appearance  to  a  microcomputer  keyboard,  except  it contains additional keys for specific CG functions. As you create text, you may store it in RAM (random access memory) and recall it as needed. Since RAM is cleared when microcomputers are turned off, most CGs use a floppy  or  hard  disk  drive  system  for  permanent  text storage. lines of 32 characters within the frill-screen scanning area  line-by-line  memory  recall,  automatic  centering, word flash, word or line underline, stand alone titling, titling  over  video  and  two-speed  roll  (or  crawl)  through all or part of the memory. You may even program the letters in certain color arrangements by using a colorizer. A cursor helps you move information to any location on the  screen. Although  the  CG  is  a  timely  means  to  display information, you should not rule out the use of other graphic  support  material. Computer Graphics Computer  graphics,  the  newest  elements  of  the television medium, have all but replaced 35mm slides for   television   work.   This   process   starts   with   an electronic  picture  recorded  on  videotape.  The  computer operator converts the picture into a digital code format and stores it either on the hard disk drive or a floppy drive.  When  the  image  is  needed,  a  graphic  artist retrieves  it  and  converts  it  into  an  electronic  picture. Now he may paint or draw a picture using an electronic pen  and  palette.  The  graphic  artist  can  add  or  delete information  and  change  the  colors  of  the  picture  and letters   at   will   while   “on-the-   air.”   Some   advanced computer graphic systems have a wide range of colors and can produce detailed animation. 14-17
