Title
(EN) AUDIENCE MEASUREMENT SYSTEM AND METHOD FOR DIGITAL BROADCASTS
(FR) SYSTEME ET PROCEDE DE MESURE DE L'AUDIENCE DE RADIODIFFUSIONS NUMERIQUES
Abstract
(EN) A method is disclosed wherein audience measurement data for digital broadcasts, both program lineup verification and statistical audience samples, are collected from data added by the broadcaster for this purpose. A coded channel ID (102) and other program identification data (104) is placed in the service ID stream and the decoder or receiving device is directed to output this data to the device's communication port. A probe (106) attached to the communication port is disclosed whereby this data is extracted and decoded for use by a data collection system (108) in statistically selected homes for accurate audience measurement of digital programming.
(FR) L'invention concerne un procédé dans lequel des données de mesure de l'audience de radiodiffusions numériques, de vérification de réglage des programmes et d'échantillons d'audience statistiques, sont collectées à partir de données ajoutées par le radiodiffuseur à cet effet. L'identification d'un canal codé et d'autres données d'identification des programmes sont placées dans le train d'identification de service, et le décodeur ou dispositif de réception transfère ces données à la porte de communication du dispositif. L'invention concerne également une sonde connectée à la porte de communication par où sont extraites et décodées les données pour être utilisées par un système de collecte de données dans des foyers statistiquement sélectionnés afin d'obtenir une mesure exacte de l'audience d'une programmation numérique.
