Method for managing rights of subscribers to a multi-operator pay-television system
First Claim
1. A method for managing rights of subscribers to a pay-television system comprising an access control system to which are connected subscriber management systems each managed by an operator and a plurality of subscriber decoders, said decoders each being equipped with a security module containing the rights for each subscriber allowing the decryption of encrypted digital data of a stream broadcasted by at least one operator, during a modification of the rights carried out by an operator in the security module of a subscriber, the method comprising:
- receiving, by the access control system, data identifying a subscriber with commands for modifying the rights in the security module of the subscriber'"'"'s decoder, the data being sent by a subscriber management system of an operator;
verifying, by a filtering module connected to the access control system, the rights'"'"' modifications according to security module resources including available storage capacity depending on format and structure of the stored rights data and rights data to be stored;
when the rights modifications are acceptable by the security module, generating a management message containing the modified rights;
transmitting said management message to the security module of the subscriber'"'"'s decoder via the broadcasted stream containing the encrypted digital data; and
if the verification of the rights modifications fails, transmitting by the subscriber management system a warning message to the subscriber, said message proposing a new configuration of the rights to said subscriber by deletion and/or replacement of the superfluous rights stored in the security module.

Abstract
The present invention proposes a method for managing rights of subscribers to a pay-television system comprising an access control system to which are connected subscriber management systems each managed by an operator and a plurality of subscriber decoders, said decoders each being equipped with a security module containing the rights for each subscriber allowing him the decryption of encrypted digital data of a stream broadcasted by at least one operator, during a modification of the rights carried out by an operator in the security module of a subscriber, the control access system receives data identifying a subscriber with modification commands of rights of said subscriber coming from a subscriber management system of an operator, generates a management message containing the modified rights and transmits said message to the security module of the subscriber via the stream containing the encrypted data, said method comprising the step of verification of the modifications according the properties and the available resources of the security module and the step of generation of the management message containing the modified rights when the result of the comparison is positive.

9. A method for managing rights of subscribers to a pay-television system comprising an access control system to which are connected subscriber management systems each managed by an operator and a plurality of subscribers'"'"' decoders, said decoders each being equipped with a security module containing the rights for each subscriber allowing the subscriber the decryption of encrypted digital data of a stream broadcasted by at least one operator, during a modification of the rights carried out by an operator in the security module of a subscriber, the method comprising:
-
receiving, by the access control system, data identifying a subscriber with commands for modifying the rights in the security module of the subscriber'"'"'s decoder, the data being sent by a subscriber management system of an operator; generating a management message containing the modified rights, and including supplementary fields containing identifiers of different operators accompanied by commands of right modification; transmitting said management message to the security module of the subscriber'"'"'s decoder via the broadcasted stream containing the encrypted digital data, said security module including a filtering module, which stores, analyzes the management message and verifies the modifications of rights transmitted by an operator according to a storage area capacity of the security module attributed to said operator; and if the verification of the modification of rights fails, displaying a suitable warning message on a screen associated with the decoder, the message including an indication to request a new modification of the rights that is compatible with resources of the security module.
