ABSTRACT:
A teletext system for broadcast of pages of magazines to be displayed on television receiver screen. A subscriber entitled to receive a magazine can select a desired page thereof by actuating a keyboard to transmit 8-bit words belonging to two groups: first properly said character words and second function words. Among the function words, there are page flag words which indicate that a page number word follows it and make the selection possible. A row flag word is followed by a row number word to indicate the vertical address of a sequence of characters in a page. Adaptation means are provided for adapting the voltage/light characteristics, as in a current gamma correction, which permits correctly displayed logic signals.
