    Abstract: A method for the storage of sub-pages of a teletext service comprises a page (Y0) to be stored, said page (Y0) to be stored comprising at least one sub-page. A desired sub-page is stored (E2, E4) and, as the case may be, sub-pages neighboring the desired sub-page are stored (E5) until a maximum number of stored sub-pages (MAXY0) is reached or until a limit number (NB_LIMY0) of sub-pages of the page to be stored is reached. In one example, the desired sub-page is the rank 1 sub-page of the page to be stored, and the neighboring sub-pages, if any, are the following sub-pages. A user thus has direct access to the start of the information contained in the page to be stored. In another example, the desired page is a rank X0 sub-page requested by a user, and the sub-pages neighboring the desired sub-pages are pages with ranks 1, X0+1, X0-1, etc.
