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.
