Abstract

L'invention concerne un dispositif et un procédé de transmission de programme, un dispositif d'émission de programme et un dispositif de réception de programme permettant au côté récepteur de sélectionner facilement des informations particulières au côté récepteur parmi les informations transmises. Le dispositif d'émission de programme (appareil d'émission) ajoute différents identificateurs aux informations spécifiques devant être diffusées en même temps par différents canaux. Lorsque le dispositif de réception de programme (appareil de réception) reçoit les informations par un canal sélectionné, si l'identificateur ajouté aux informations spécifiques sur le canal est différent de l'identificateur particulier prédéfini dans le dispositif de réception de programme (appareil de réception), des données spécifiques sont à ce moment remplacées par des informations spécifiques auxquelles on ajoute l'identificateur particulier. Ainsi, le côté récepteur sélectionne facilement les informations spécifiques particulières au côté récepteur parmi les informations spécifiques transmises.
