Abstract: A method for broadcasting protected multimedia content includes, at predetermined intervals, having an access-rights server broadcast each new right of access to the broadcast multimedia content only to those terminals whose logins are included in a broadcast list. In response to a predetermined event, a terminal sends, to the access-rights server, via a point-to-point connection, a status message indicating, to the access-rights server, that the terminal is in its ready state. Alternatively, if the terminal is occupied, it avoids sending a status message. In the absence of reception of the status message that was expected in response to the predetermined event, the access-rights server automatically removes the identifier of the terminal from the broadcast list.

Abstract: A Method for supplying protected multimedia content during which a terminal a) acquires a service date from a date server and b) evaluates a temporal criterion of a licence with respect to the last acquired service date. A headend associates with each segment of the multimedia content, its transmission date, and transmits it in a stream together with the segment. The terminal extracts from the stream the date of transmission of the segment, then it compares the extracted transmission date to the last acquired service date. And, only if the extracted transmission date is later than the last acquired service date, acquires it as service date, and uses it as last acquired service date on an execution of the step b) between two successive executions of the step a).
