Abstract
Abstract A television receiver including a teletext decoder is adapted to continue the further acquisition of a page in another memory after said page has been received. After each reception of the page it is checked whether this page has already been previously received and stored with the same sub-code. If this is not the case, the acquisition is continued in a further memory so that all sub-pages of a rotating page are stored without the user's intervention being required and without the displayed page rotating. If the sub-page has already been previously stored, the acquisition is continued in the previously written memory. If the sub-page is a displayed sub-page, it is replaced by the new version.
