Abstract

L'invention concerne un récepteur audio/vidéo (IEG) pour recevoir des données audio/vidéo par l'intermédiaire d'un réseau de télécommunication bidirectionnel (1). Pour accéder à des sources audio/vidéo prédéterminées dans ce réseau de télécommunication bidirectionnel (1), ce récepteur possède une unité d'accès (2), un explorateur (7) et une unité d'accès au menu de sélection (8). Une unité de sortie (3) sort les données envoyées par les sources audio/vidéo auxquelles le récepteur a eu accès. L'unité d'accès au menu de sélection (8) produit un menu de sélection prédéterminé des sources audio/vidéo disponibles dans le réseau de télécommunication bidirectionnel (1), ce qui facilite particulièrement l'utilisation de ce récepteur audio/vidéo (IEG).
