Abstract

Même lors de la transmission d'une grande quantité de codes de lecture optique depuis un côté distributeur d'informations, il est possible de réduire la quantité de données de transmission et de générer différents codes de lecture optique conformément à la condition d'un côté de terminal de réception utilisateur. Dans un récepteur de diffusion de l'invention (20), un récepteur de diffusion (21) reçoit des données texte comprenant des données source d'un code bidimensionnel comme source du code bidimensionnel (code de lecture optique) via la diffusion vidéo. Une unité de génération de code bidimensionnel (23) génère un code bidimensionnel en fonction des données de référence déterminées par un récepteur de diffusion individuel ou son utilisateur et les données de texte reçues. Ainsi, par exemple, le générateur de code bidimensionnel (23) génère un code bidimensionnel en en choisissant un hors des données source du code bidimensionnel en fonction des données de référence, ajoutant les données de référence aux données source du code bidimensionnel et jugeant de l'état des données de référence.
