Abstract

La présente invention se rapporte à un système automatisé permettant de surveiller un contenu de diffusion et de publicité. Un système automatisé permettant de surveiller un contenu de diffusion et de publicité selon un mode de réalisation de la présente invention comprend un seul dispositif de masquage d'informations qui insère un signal de masquage généré à l'aide des seules informations d'un contenu de diffusion et de publicité approprié à chaque élément du contenu de diffusion et de publicité, et transmet le contenu de diffusion et de publicité à une station de diffusion. Lorsque la station de diffusion transmet le contenu de diffusion et de publicité dans lequel est inséré le signal de masquage, un dispositif d'enregistrement local enregistre le contenu à un intervalle de temps prédéterminé et transmet le contenu de diffusion enregistré à un intervalle de temps prédéterminé à un dispositif permettant de surveiller le contenu de diffusion et de publicité. Ensuite, le dispositif permettant de surveiller le contenu de diffusion et de publicité détecte le signal de masquage provenant du contenu de diffusion enregistré afin de diviser le contenu de diffusion enregistré d'après le contenu de diffusion et de publicité enregistré et transmet le résultat de la comparaison entre les informations concernant le contenu de diffusion et de publicité enregistré et les informations concernant le contenu de diffusion et de publicité d'origine.
