Abstract

Un générateur (21) d'image insérée dans le guide comprend une sortie destinée à commande un moniteur (62) de visualisation et une entrée prévue pour recevoir un signal de télévision. Un générateur (34) d'affichage envoie des signaux de commande à la sortie en même temps que le moniteur (62) de visualisation. Des informations de guide électronique de programme (GEP) sont extraites du signal de télévision et stockées dans une mémoire (26). La taille des pixel du signal de télévision est réduite puis stockée dans la mémoire (26). Les données GEP et le signal de télévision sont récupérés dans la mémoire (26) puis stockés dans le générateur (34) d'affichage. Les données GEP et le signal de télévision sont envoyés du générateur (34) d'affichage à la sortie dans un flux de données continu prévu pour produire sur le moniteur (62) un affichage (10) d'image insérée dans le guide. De préférence, le générateur (21) d'image insérée dans le guide est réalisé sur une seule puce à circuits intégrés.
