Patent

CA 2653558

A method and apparatus for recognizing and synchronizing to in-band data at a multimedia device is provided. A content stream includes in-band data. The in-band data is processed and in-band data pattern data associated with the content stream are created. Metadata are attached to the event identification data. The event identification data are provided to multimedia devices which receive broadcasted multimedia content streams containing video programs with in-band data. The in-band data are processed and compared to the event identification data. If a match occurs, the multimedia device uses the metadata to perform specified actions.

L'invention concerne un procédé et un dispositif servant à reconnaître et à synchroniser des données intrabande au niveau d'un dispositif multimédia. Un flux de contenu comprend des données intrabande. Ce procédé consiste à traiter les données intrabande et à créer une configuration de données intrabande associée au flux de contenu. On relie ensuite des métadonnées aux données d'identification d'événement qui sont transmises à des dispositifs multimédia qui reçoivent des flux de diffusion de contenu multimédia contenant des programmes vidéo comportant des données intrabande. On traite ces dernières et on les compare aux données d'identification d'événement. Dans le cas d'une correspondance, le dispositif multimédia utilise les métadonnées afin de mettre en oeuvre des actions spécifiques.
