摘要
The present invention proposes a method for managing rights of subscribers to a pay-television system comprising an access control system (CAS) to which are connected; subscriber management systems (SMS1, SMS2, SMS3) each managed by an operator (OPl, OP2, OP3) and a plurality of subscriber decoders (STBn), said decoders (STBn) each being equipped with a security module (SMn) containing the rights for each subscriber allowing him the decryption of encrypted digital data of a stream broadcasted by at least one operator (OPl, OP2, OP3), during a modification of the rights carried out by an operator in the security module (SMn) of a subscriber, the control access system (CAS) receives data identifying a subscriber with modification commands C(Dm) of rights of said subscriber coming from a subscriber management system (SMS1, SMS2, SMS3) of an operator (OPl, OP2, OP3), generates a management message (EMM1) containing the modified rights (Dm) and transmits said message (EMM1) to the security module (SMn) of the subscriber via the stream containing the encrypted data, said method is characterized in that the modifications are verified according the properties and the available resources of the security module (SMn) and in that the management message (EMM1) containing the modified rights (Dm) is generated when the result of the comparison is positive.
