A teletext television receiver has a character memory comprising a common language set of characters and a plurality of sets of national option characters, each of which latter sets makes up a complete national language set when combined with the common language set. The totality of characters are arranged for addressing in two different modes. In one addressing mode, only one of the national option sets can be selected for page display as determined by control bits contained in the page header, so that the page can be only in one language. In the other addressing mode, all the national option sets can be selected for page display as determined by ghost row information of an acquired page, or locally by the receiver. This allows a display page to be in more than one language. FIGS. 3 and 4 show the code tables for the two addressing modes.
