ABSTRACT:
In this apparatus, a composite memory 5 includes a managing memory (5g) containing for each line of the frame to be displayed, a word made up of information relating to the composition of the line in question. This information can define a base color, the number of memory planes, and, if appropriate, a base address of a zone of a zone memory (5z) which contains the data relating to the parts of the image which contain only typographic or graphic information. If the number of planes is equal to zero, said base color becomes a constant background color in the totality of the line to be displayed. The contents of the control memory are read out, word by word, from the control memory at the frequency of the line synchronization signal for the screen.
Application to teletext systems.
