Abstract

Le problème décrit par la présente invention est de permettre de réaliser un étiquetage de contenus plus souple. La solution selon l'invention porte sur un appareil de traitement d'informations comprenant : une unité d'acquisition d'informations de position qui acquiert les informations de position d'un élément fonctionnel associé au temps écoulé qui est relatif à un contenu en cours de reproduction ; et une unité d'étiquetage ajoutant au contenu les informations de position, qui servent alors d'informations d'étiquette, et cela aboutit à l'étiquetage du contenu.
