Abstract

L'invention concerne un signal de programmes de radio-diffusion contenant non seulement une chaîne analogique ou numérique mais aussi un canal de données pour des informations supplémentaires. Le canal de données contient une première série d'informations dynamiques supplémentaires qui donnent un aperçu du contenu de la suite de l'émission actuellement diffusée sur la chaîne et au moins le titre et la chaîne de l'émission suivante diffusée sur la même chaîne (Fig. 2). Selon une variante, le canal de données contient une troisième série d'informations dynamiques supplémentaires contenant un aperçu au moins des titres et chaînes concernant les émissions choisies côté émetteur et dont le contenu est apparenté à celui de l'émission actuellement diffusée sur la chaîne (Fig. 4). Selon une troisième possibilité, le canal de données contient une seconde série d'informations dynamiques représentant des mots-clés thématiques relatifs au contenu de l'émission actuellement reçue (Fig. 3).
