  • the first document does not meet current needs in view of the proliferation of conditional access systems since it only allows the operation of a single encryption system.
  • the second document certainly allows the use of several decryption systems. But it only authorizes it by multiplying the number of card readers, each reader being assigned to a given decryption and therefore not adaptive.

  • the present invention overcomes the drawbacks of current devices.
  • Another object of the invention is to avoid complications linked to the installation or updating of conditional access systems when the user wishes to modify his rights (change operator or subscription, for example). Indeed, it has a multiplicity of conditional access systems and, if an update is required, it can be done by downloading. Other objects and advantages will appear during the following description which is not limitative of the invention.
