摘要： A method of acquiring access rights to conditional access content. The method comprises receiving an access right on a first terminal through a first communication channel; storing said access right in said first terminal; sending a request for said conditional access content to a content provider, said request containing at least an identifier of an account to which said first terminal is associated, an identifier of the requested content and a piece of information concerning said access right; verifying, by said content provider, the authenticity of said access right using said piece of information concerning the access right; and when there has been a successful verification, marking said access right as used, and sending said conditional access content to at least one terminal linked to said account. The first terminal using near field communication technology (NFC) during at least one transfer of said access rights.

摘要： A method for updating a table of correspondence between a logical address associated to a user unit in a communication network and a unique identification number associated to one of a group of user units managed by a management centre, a method where messages are exchanged between said management centre and a specific user unit of said group by using said communication network, these messages being forwarded to the logical address of the specific user in said network, the method including searching in said table for the logical address of the user unit in said communication network corresponding to the unique identification number of the specific user unit; sending of messages to the user unit having the concerned unique identification number, to the logical address corresponding to said communication network; and if the messages are received incorrectly, sending a request containing an identifier of said specific user unit.

摘要： This invention relates to a Method for updating a table of correspondence between a logical address associated to a user unit in a communication network and a unique identification number associated to a user unit of a group of user units managed by a management centre, a method in which messages are exchanged between said management centre and at least one specific user unit of said group by means of said communication network, these messages being forwarded to the specific user unit using the logical address of said user unit in said network, wherein it includes the steps of searching in said table of correspondence for the logical address of the user unit in said communication network corresponding to the unique identification number of the specific user unit; of sending of messages to the user unit having the concerned unique identification number, to the logical address corresponding to said communication network; in the case of incorrect reception of the messages, sending of a request containing an identifier of said specific user unit (STB*), this request being sent to all or part of the user units (STB) forming said group; detection of a return message of a user unit (STB*) whose unique identification number (UA*) corresponds to said identifier contained in the request; determination of the logical address (AD*) in said network, used by the user unit (STB*) having transmitted the return message; verification of the logical address (AD) by establishing a communication between the management centre and the user unit (STB*) and authentication of the specific user unit by the management centre; storage in the table of correspondence (TC) of the management centre of said logical address (AD*) of the user unit in said network, in connection with said unique identification number (UA*) of the user unit (STB*) having transmitted the return messages.
