bei dem für jeden aufzuzeichnenden Bildpunkt eine konstante Bitzahl übertragen wird, die bei der Übertragung eines Mehrfarben-Bilds in eine der Farb komponentenanzahl entsprechende Anzahl von Gruppen, die jeweils den Farbkomponentenwert eines Bildpunkts darstellen, unterteilt sind, während bei der Über tragung eines Einfarben-Bilds alle einem jeweiligen Bildpunkt entsprechende Gruppen denselben Tonwert des Bildpunkts enthalten,
und bei dem in der Empfangsstation überprüft wird, ob alle Gruppen eines jeweiligen Bildpunkts in ihren Werten im wesentlichen übereinstimmen, und wenn dies der Fall ist, einfarbig aufgezeichnet wird.
einer Empfangseinrichtung (21, 28, 35) zum Em pfangen von punktweise aufgelösten digitalen Bildda ten von einer Übertragungseinrichtung (7) zum Über tragen eines Mehrfarbbilds und eines Einfarben- Bilds,
bei dem für jeden aufzuzeichnenden Bildpunkt eine konstante Bitzahl empfangen wird, die bei der Übertragung von ein Mehrfarben-Bild repräsentieren den Bilddaten in eine der Farbkomponentenanzahl ent sprechenden Anzahl von Gruppen, die jeweils den Farb komponenten eines Bildpunkts darstellen, unter teilt sind, während bei der Übertragung von ein Ein farben-Bild repräsentierenden Bilddaten das durch alle einem jeweiligen Bildpunkt entsprechenden Grup pen repräsentierte Bild einem monochromatischen Bild entspricht,
einer Erkennungseinrichtung (24′-1 bis 24′-3, 24′-18 bis 24′-20), die erkennt, ob alle Gruppen eines jeweiligen Bildpunkts in ihren Werten im wesent lichen übereinstimmen, und
einer Verarbeitungseinrichtung (26, 33, 40) zum Durchführen einer mehrfarbigen und einer einfarbigen Aufzeichnung,
wobei dann, wenn das durch alle Gruppen eines jeweiligen Bildpunkts repräsentierte Bild ein mono chromatisches Bild ist, ein einfarbiges Bild aufge zeichnet wird.
