Definitions

  • the present disclosure relates generally to verification systems, and more particularly, to methods and apparatus to verify consumption of programming content.
  • PVR personal video recorders
  • methods to collect viewing data depend on the programming being view at the time of broadcast (i.e., realtime).
  • signatures of a program taken at a household are either collected with broadcast timestamp information or associated with a time at which they were received at the household receiver (e.g., a set top box).
  • the signatures are then compared to either reference signatures having the same broadcast time stamp or reference signatures that were broadcasted at or around the same time to identify a match. Comparing broadcast time reduces the amount of signature comparisons that are required to identify a match.
  • PVRs allow viewers to skip programming content such as commercials at their discretion to avoid consumption of the programming content. Thus, audience measurement companies are researching different ways to verify programming content is shown to viewers. BRIEF DESCRIPTION OF THE DRAWINGS

Abstract

L'invention concerne des procédés et un appareil permettant de vérifier la consommation de contenu. Dans un procédé exemplaire, une bibliothèque de contenus (240) est engendrée (232) au sein d'une structure de données (234). Ladite bibliothèque de contenus comporte au moins un identificateur de contenu associé au contenu de programmation. Ledit contenu de programmation peut être introduit dans un flux de contenu. Un flux de contenu contenant un contenu destiné à la diffusion au niveau d'un dispositif de diffusion (220) est reçu. Afin de vérifier la consommation du contenu de programmation, un identificateur de contenu de diffusion associé au contenu de diffusion est comparé (236) à au moins un identificateur de contenu de la bibliothèque de contenus.
