Fi g. 1 zeigt eine an einen Rechner 10 anschließbare Raster-Anzeigevorrichtung 16, ein graphisches Eingabegerät 12 und ein Tastatur-Eingabegerät 14. Der Rechner 10 und die dazugehörigen Eingabegeräte sind allgemein bekannte Geräte, die hier nicht näher erläutert werden müssen. In dem beschriebenen Ausführungsbeispiel dient zur optischen Anzeige eine konventionelle Kathodenstrahlröhre (CRT) 18, statt dessen könnte aber auch jedes andere Anzeigegerät verwendet werden, das geeignet ist, vom System 16 erzeugte Rasterausgaben zu verarbeiten und anzuzeigen.
Das besondere Dekodierungsschema, welches in dem beschriebenen Ausführungsbeispiel benutzt wird, ist in
