Abstract

On the transmission side it is possible, in addition to the basic teletext data from conventional teletext pages, to transmit supplementary data for a teletext page in the form or one or more associated supplementary pages, with pages numbered in the hexadecimal system, structured in the format of original teletext pages and stored temporarily on the reception side separately from the basic data of a desired teletext page. The numbers of the supplementary pages coded in the hexadecimal system outside the decimal system are related, according to a fixed system, to the numbers of the associated conventional teletext pages numbered in the decimal system and selectable via the ten-key keypad. To facilitate compatible transmission of teletext pages for 16:9 aspect ratio screens, further supplementary data with an independent image content are transmitted instead of or in addition to the supplementary data, in the same code and format. The further supplementary data are displayed on a screen with a 16:9 aspect ratio in the image field alongside a conventional teletext page or alongside a conventional television picture having a 4:3 aspect ratio.
