Title
(EN) AUDIENCE RATING SYSTEM FOR DIGITAL TELEVISION AND RADIO
(FR) SYSTEME DE CALCUL DU TAUX D'ECOUTE POUR TELEVISION ET RADIO NUMERIQUES
Abstract
(EN)
An audience rating system for digital television and radio, using identification codes in control streams (C) of time-multiplexed digital transmissions (12). When a television set (22) or radio, that is being monitored pursuant to the system is turned on and tuned to a channel, and each time that the channel is changed, an identification code for each audio, video or auxiliary digital stream of the channel is extracted from the control stream, and recorded along with the time. The time is also recorded when the television set or radio is turned off. This data makes it possible to determine what stations, channels, and programs members of the audience being monitored are watching or listening to at any particular time.
(FR)
L'invention concerne un système de calcul du taux d'écoute pour télévision et radio numériques. Ce système fait appel à des codes d'identification compris dans des trains (C) de contrôle d'émissions (12) numériques à multiplexage dans le temps. Lorsqu'un poste (22) de télévision ou de radio contrôlé au moyen de ce système est allumé et réglé sur un canal, et à chaque changement de canal, un code d'identification pour chaque train numérique audio, vidéo ou train numérique auxiliaire du canal est extrait du train de contrôle et enregistré en même temps que l'heure. L'heure est également enregistrée lorsque le poste de télévision ou de radio est éteint, Ces données permettent de déterminer quelles stations, canaux et émissions sont regardés ou écoutés à un quelconque moment par les auditeurs faisant l'objet du contrôle.
