Abstract
A method and apparatus for processing identification signals in a data signal (teletext signal) which is cyclically repeated within a television signal and which can be displayed in the form of single still television pictures (teletext pages), whereby the manual entry of numbers for selecting the teletext pages is superfluous and the desired teletext pages can be selected in a simple and flawless way by searching a part of the teletext signal constituting at least a part of the contents of a selected teletext page for signal sequences representing three-digit, natural numbers, which sequences are separated as identification signals and are stored as signals assigned to the selected teletext page.
