摘要

Method for distributing multimedia licenses by a server to a plurality of user devices in a distribution system of a multimedia service, the access of which is protected by a first protection. This method comprising verifying that computing resources used by the server do not exceed a maximal threshold, if so, generating and then transmitting regular licenses including said first protection in response to user device requests, otherwise switching the server to a singular mode of distribution aiming to protect the access to the multimedia service using a second protection, independent of the first protection; to generate and to transmit to the devices one singular license comprising the second protection; to verify that the computing resources do not exceed the maximal threshold, if so, to switch from the singular mode to a regular mode so as to protect the access to the multimedia content using only said first protection.
