Abstract

A method of distributing a message from a message administration service to a subscriber receiver decoder of a digital multimedia network comprises transferring a determined message for a determined receiver decoder from the message administration service to a point to point communication system distinct from the multimedia network. A destination point address of a receiver in the point to point communication system is determined, corresponding to the determined receiver decoder. The determined message is buffered in the point to point communication system, and retrieved at the determined receiver decoder from the receiver.

Claims

1. A method for distributing a message from a message administration service to a subscriber receiver decoder of a digital multimedia network, the method comprising:

transferring a determined message for a determined receiver decoder from the message administration service to a point to point communication system distinct from the multimedia network, the determined message comprising an Entitlement Management Message (EMM),

determining a destination poin address of a receiver in the point to point communication system, corresponding to the determined receiver decoder,

buffering the determined message in the point to point communication system,

retrieving at the determined receiver decoder the determined message from the receiver.

2. The method from claim 1, further comprising:

buffering the determined message at an emitter point in the point to point communication system, corresponding to the message administration service,

generating a siganl of availability at the receiver,

triggering for emission fo the determined message on reception of the signal of availaibility,

emitting the determined message to the receiver.

3. The method according to claim 1, further comprising

receiving at the receiver the determined message,

buffering at the receiver the determined message.

4. The method according to claim 1, further comprising:

generating a confirmation of receipt at the receiver,

emitting the confirmation of receipt to the emitter point.

5. The method according to claim 4, in which the confirmation of receipt comprises one or a plurality of items of additional information from the following set:

a status of the receiver decoder, a status of a daughter smartcard used with the receiver decoder, a version number of an element of the receiver decoder.

6. The method according to claim 5, further comprising:

extracting an item of additional information from the confirmation of receipt,

evaluating the item of additional information to determine a legal status of the receiver decoder.

7. The method according to claim 1, in which the point to point communicaiton system is a mobile phone network.

8. The method according to claim 1, the message administration service being comprised in a Subscriber Authorization System.

13. The method according to claim 2, further comprising:

receiving at the receiver the determined message,

buffering at the receiver the determined message.

14. The method according to claim 2, further comprising:

generating a confirmation of receipt at the receiver,

emitting the confirmation of receipt to the emitter point.

15. The method according to claim 3, further comprising:

generating a confirmation of receipt at the receiver,

emitting the confirmation of receipt to the emitter point.

9. A method for receving a determined Entitlement Management Message (EMM) at a determined subscriber receiver decoder in a digital multimedia network, the determined subscriber receiver decoder being enabled to receive information through a mobile phone communicaiton network distinct of the digital multimedia network, the method comprising:

receiving in a mobile phone modem of the receiver decoder a message containint at least the determined EMM, the message being addressed specifically to the mobile phone modem of the determined receiver decoder,

storing at least the EMM in a storage of the mobile phone modem.

10. The method according to claim 9, further comprising retrieving the EMM from the storage into the determined receiver decoder.

11. A receiver decoder for a digital multimedia network, the receiver decoder comprising:

a mobile phone modem operatively connected to the receiver decoder,

a destination point address uniquely attributed to the mobile phone modem,

a storage space in the mobile phone modem to store at least an Entitlement Management Message (EMM).

12. The receiver decoder according to claim 11, wherein the mobile phone modem may receiver the EMM from the mobile phone network and store the EMM independent of a status of the receiver decoder.
