Abstract

Un récepteur (30) répond à une diversité de programmes transmis par différentes stations de radiodiffusion (22). Chaque station de radiodiffusion transmet des programmes (23) et des codes (25) qui décrivent les programmes associés. Lorsque l'on appuie sur une touche de réponse (32) d'un récepteur radio pendant un programme donné, le récepteur transmet automatiquement un code de réponse qui accuse réception du programme. L'auditeur radio n'a donc pas besoin de composer manuellement un numéro de téléphone et de donner verbalement une réponse à un opérateur de la station de radiodiffusion.
