Abstract
A method of receiving teletext pages is disclosed. The receiver creates a table of flags indicating for each page whether said page is either available or not available in the transmission. In order to register the absence of pages which are no longer transmitted, two tables (460, 461) are alternately used. While one table is created, the other one is read to provide the presence or absence of information. The creation of a table is deemed completed after a given number of pages has been received more than once.
