(EN) INTERACTIVE CONTENT ACQUISITION USING EMBEDDED CODES
(FR) ACQUISITION DE CONTENU INTERACTIF À L’AIDE DE CODES INTÉGRÉS
Abstract
(EN) Methods and devices are provided to obtain associated information for a multimedia content. One such method includes receiving a content at a receiver device equipped with a watermark detector, performing watermark detection on the received content to extract a payload of an embedded watermark. The payload comprises a first field that includes a server identifier and a second field that includes an interval identifier associated with the server identifier. The first field provides a mapping to an Internet address accessible to retrieve metadata associated with content segments identified by the watermark payload. In this method, based on the detected watermark payload, a query is formed and transmitted to a server identified by the Internet address, and a response to the query is received from the server that includes metadata associated with the content.
(FR) L’invention concerne des procédés et dispositifs pour obtenir des informations associées pour un contenu multimédia. Ce type de procédé comprend les étapes consistant à : recevoir un contenu au niveau d’un dispositif récepteur équipé d’un détecteur de filigrane, effectuer la détection de filigrane sur le contenu reçu pour extraire une charge utile d’un filigrane intégré. La charge utile comprend un premier champ qui contient un identifiant de serveur et un deuxième champ qui contient un identifiant d’intervalle associé à l’identifiant de serveur. Le premier champ permet d’obtenir une mise en correspondance avec une adresse Internet accessible pour récupérer des métadonnées associées à des segments de contenu identifiés par la charge utile de filigrane. Dans ce procédé, à partir de la charge utile de filigrane détectée, une interrogation est formée et envoyée à un serveur identifié par l’adresse Internet, et une réponse à l’interrogation est reçue du serveur, laquelle contient des métadonnées associées au contenu.
