  • Patent number: 7614079
    Abstract: A method for transmitting entitlement management messages (EMM) controlling access to data and/or services to be provided to plural terminals in a data exchange network. The method, at the transmitting side: defines a set of EMM type messages as a function of at least one criterion representative of a type of data and/or services provided; defines plural types of logical transmission channels and associates at least one parameter to each type of channel to inform terminals of the EMM types transmitting on each described logical channel; assigns at least one channel among the defined logical transmission channels to each EMM message type; transmits the parameter and the logical channels to each terminal; multiplexes the logical transmission channels in the same data stream; and transmits the data stream to terminals. In the method, on reception each terminal filters incoming EMMs as a function of the parameter and at least one state parameter depending on a routine operation of the terminal.
