Title
(EN) METHOD FOR THE PROVISION OF CHARGED CONTENTS OF DIGITAL MULTIMEDIA BROADCASTING
(FR) PROCEDE DE DISTRIBUTION DE CONTENUS PAYANTS DE RADIODIFFUSION MULTIMEDIA NUMERIQUE
Abstract
(EN) Provided is a method for the provision of charged contents of digital multimedia broadcasting based on the provision of charged contents protected by a protection key and the decryption of the charged contents using a decryption key, wherein the transmission of the charged contents protected by the protection key is performed via a digital multimedia broadcasting network and the transmission of a request message for the charged contents from a user and an authorization message for the charged contents from a broadcasting system is performed via a communication network. This method ensures effective utilization of the narrow bandwidth of digital multimedia broadcasting, while solving the problem of the conventional provision of charged contents based on conditional access system. In addition, customer database management and charging can be done using available means of communication. The broadcasting business operator can save the cost of customer database management and charging.
(FR) La présente invention concerne un procédé de distribution de contenus payants de radiodiffusion multimédia numérique qui repose sur la distribution de contenus payants protégés par une clé de protection et le déchiffrement des contenus payants à l'aide d'une clé de déchiffrement, ladite transmission des contenus payants étant réalisée par un réseau de radiodiffusion multimédia numérique et la transmission d'un message de requête concernant les contenus payants, émise par un utilisateur et d'un message d'autorisation concernant les contenus payants, émis par un système de radiodiffusion, étant effectuée par le biais d'un réseau de communication. Ce procédé assure l'utilisation efficace de la largeur de bande étroite de la radiodiffusion multimédia numérique, tout en résolvant le problème de la distribution classique de contenus payants à partir d'un système d'accès conditionnel. De plus, la gestion de la base des données de clients et la facturation peuvent être faites au moyen de dispositifs de communication disponibles. L'opérateur commercial de radiodiffusion peut économiser le coût de la gestion de la base des données de clients et la facturation.
