Editing terminals and graphics digitizers
Peter L. Mothersole, Norman W. White · 2023
The page on the editing terminal is normally displayed as far as possible in the same way as it will be seen on a domestic receiver. The disc controller and associated disc drive is an optional feature that is often fitted to editing terminals. On editing terminals that are equipped with a teletext decoder, the instructions concerning which magazine and page should be captured are entered on the command row. To prevent unauthorized editing when a number of editing terminals are used in conjunction with the system, &s;barring&s; may be included, so that only certain terminals can communicate with particular pages. Graphics digitizers (sometimes called graphics cameras) are used to produce complex &s;pictures&s; such as maps or pages for educational type programmes. It is not normal practice to use a graphics digitizer with each editing terminal in an editing suite, but to switch the digitizer between terminals.
