    摘要: A method for securely receiving a multimedia content by a client device operated by one or more operator(s) involving a dedicated provisioning server of a security provider managing symmetric secrets used by the client devices and operators license servers. The provisioning server provides to the client device one or more generations of operator specific unique device secrets, which are then exploited by the various operators' license servers to deliver licenses such that authorized client devices can consume protected multimedia contents.

    摘要: A method to bind the use of a digital audio / video service data receiver to a network on which at least one services provider broadcasts access controlled and free digital audio / video services streams,, the method is characterized by steps of: receiving by the receiver a periodic signal transmitted by a conditional access system server via the network, said periodic signal being processed by a run time software embedded in the receiver to check legitimacy of the network, displaying services available on the network only if said run time software recognizes the periodic signal as indicating network legitimacy, checking operability of the run time software and if necessary taking actions to enforce limitation of using the receiver on the network checked as legitimate. The invention further discloses a receiver bound to a specific network configured to perform the method.

    摘要: Methods and apparatus are provided for providing a DRM service by a user terminal apparatus consuming DRM content in a service environment that provides the DRM content using a plurality of incompatible DRM systems. A license corresponding to the DRM content is acquired from a service providing apparatus that provides the DRM content. It is determined whether the license is a common license having a common DRM interface format. The common DRM interface format of the common license is converted to a format of a first DRM system installed in the user terminal apparatus, when the license is the common license. The license having the format of the first DRM system is applied in reproducing the DRM content. The common license is provided from the service providing apparatus to the user terminal apparatus through a common DRM interface when the service providing apparatus does not support the first DRM system.

    摘要: Systems and methods are disclosed for performing anti-piracy countermeasures in order to prevent unauthorized access of protected content. A conditional access system may be modified to include a counter. The counter is incremented every time the conditional access system receives a request that is a potential indication of pirate activity. The counter may also be decremented every time the conditional access system receives a request indicative of legitimate activity. If the conditional access system receives a management message containing a key required to access content keys, the conditional access system checks the counter. If the counter is below a threshold value, the conditional access system obtains the key. However, if the counter is above the threshold value, the conditional access system disregards the key contained in the management message, thereby losing access to protected content.
