Abstract

L'invention concerne un récepteur de données transmises pour télévision. Le récepteur comporte des moyens pour extraire les codes de numéro de page, de journal et de temps de l'information reçue, des moyens pour établir des codes de référence correspondants, un décodeur 10, 14, 18, 19, 22 fonctionnant en réponse aux codes d'entrée et de référence pour produire, lorsqu'ils sont égaux, un signal d'acceptation de page et des moyens de commutation 20, 22, 21 qui peuvent être actionnés pour rendre le décodeur non sélectif en ce qui concerne au moins un chiffre du numéro de page de sorte que le signal d'acceptation peut être produit quelle que soit la valeur de ce chiffre. Application aux systèmes de télévision du type << télétext >>.
