Method for providing, by way of an electronic licence server, in a system for providing multimedia contents, a licence allowing a terminal of a user of the system to access a multimedia content, this licence being dependent both on an identifier of the multimedia content and on an identifier of the terminal or of the user, the method in which: a) the server receives a request including the identifier of the multimedia content and the identifier of the terminal or of the user, b) the server computes a licence including at least one access data needed by the terminal to access the multimedia content, this access data being dependent on the identifier of the multimedia content and on the identifier of the terminal or of the user, c) the server transmits, in response to the request, the licence computed in the step b), d) the terminal receives the licence computed in the step c), and uses it to access the multimedia content, characterized in that: - before the step a) the method includes a step e) comprising: • the obtaining of a first recommendation list for this user, this first list containing a limited number of identifiers of multimedia contents from among a larger set of multimedia contents available in the system, the multimedia contents identified by this first list having a higher probability of being accessed by the terminal of the user than the other multimedia contents of the larger set, this first list being constructed according to the identifier of the user and a database of pre-stored data on the basis of which it is possible to compute a probability that any multimedia content available in the system will be accessed by the terminal of the user, • the automatic selection, from this first list, of at least one multimedia content identifier, and • for each automatically selected identifier, the pre-computing of at least one access data using this multimedia content identifier and the identifier of the terminal or of the user, and - in the step b), the server searches for the identifier of the multimedia content received in the step a) from among the identifiers automatically selected in the step e), then, in the event of success, selects the pre-computed access data corresponding to this identifier, and, in the event of failure, generates this access data. a) the server receives a request including the identifier of the multimedia content and the identifier of the terminal or of the user, b) the server computes a licence including at least one access data needed by the terminal to access the multimedia content, this access data being dependent on the identifier of the multimedia content and on the identifier of the terminal or of the user, c) the server transmits, in response to the request, the licence computed in the step b), d) the terminal receives the licence computed in the step c), and uses it to access the multimedia content, - before the step a) the method includes a step e) comprising: • the obtaining of a first recommendation list for this user, this first list containing a limited number of identifiers of multimedia contents from among a larger set of multimedia contents available in the system, the multimedia contents identified by this first list having a higher probability of being accessed by the terminal of the user than the other multimedia contents of the larger set, this first list being constructed according to the identifier of the user and a database of pre-stored data on the basis of which it is possible to compute a probability that any multimedia content available in the system will be accessed by the terminal of the user, • the automatic selection, from this first list, of at least one multimedia content identifier, and • for each automatically selected identifier, the pre-computing of at least one access data using this multimedia content identifier and the identifier of the terminal or of the user, and • the obtaining of a first recommendation list for this user, this first list containing a limited number of identifiers of multimedia contents from among a larger set of multimedia contents available in the system, the multimedia contents identified by this first list having a higher probability of being accessed by the terminal of the user than the other multimedia contents of the larger set, this first list being constructed according to the identifier of the user and a database of pre-stored data on the basis of which it is possible to compute a probability that any multimedia content available in the system will be accessed by the terminal of the user, • the automatic selection, from this first list, of at least one multimedia content identifier, and • for each automatically selected identifier, the pre-computing of at least one access data using this multimedia content identifier and the identifier of the terminal or of the user, and - in the step b), the server searches for the identifier of the multimedia content received in the step a) from among the identifiers automatically selected in the step e), then, in the event of success, selects the pre-computed access data corresponding to this identifier, and, in the event of failure, generates this access data.
