Abstract

Procédé et appareil de production et de collecte de statistiques d'audience dans un système de télévision par câble (100). Un gestionnaire de système (310) transmet une ou plusieurs heures d'enregistrement en aval vers un ou plusieurs terminaux éloignés (120, 315a-315c) indiquant une heure future à laqeuelle le terminal (120, 315a-315c) doit enregistrer les statistiques d'audience. Les terminaux éloignés (120, 315a-315c) enregistrent en mémoire (503) le ou les heures d'enregistrement et, lorsque l'heure d'enregistrement correspond à l'heure réelle, les terminaux éloignés (120, 315a-315c) enregistrent en mémoire les statistiques d'audience. Ensuite, en réponse à un signal d'invitation à émettre provenant du gestionnaire de système (310), les terminaux à monter sur téléviseur (120, 315a-315c) transmettent les statistiques d'audience enregistrées au préalable, en même temps qu'un code horaire correspondant à l'heure à laquelle les statistiques ont été enregistrées, en amont vers le gestionnaire de système (310), lequel traite ces informations de la manière appropriée.
