  • Patent number: 4701794
    Abstract: A television receiver which is suitable for displaying teletext pages comprises a control system including a microcomputer. The microcomputer is coupled to a volatile memory which comprises a plurality of page number registers. A page number can be temporarily stored in each of these registers. With the aid of a keyboard the user makes known which page numbers he wants to have stored in the different registers and the stored page numbers represent a first series of pages. One single read key (RCL) is provided for the display of such a page. Each time this key is depressed once, a different page belonging to the first series appears on the picture screen. The sequence in which the pages appear is the same as the sequence in which the user has keyed-in the relevant page numbers. This sequence can be interrupted by the occurrence of a preselected operating instruction in response to which a number of teletext pages not associated with said first series can be displayed on the picture screen.
