摘要：In order to allow several users of an interactive videotex station protected access to stored information words, such as personal account numbers, videotex page numbers or code words for example, individual data keys (D1 to D14) are freely assigned to the information words and are released for output after a call word has been entered. A specific set of information words is assigned to each call word and can be called up by the data keys (D1 to D14). For example, five call words can be stored in the videotex station which are each permanently assigned to 28 information words. Using the 14 data keys (D1 to D14) and a shift key, the 28 information words can be output after the associated call word has been entered. The information words are stored in a battery-buffered semiconductor memory (S2) so that the contents are retained even after the operating voltage has been switched off. <IMAGE>
