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 or decoder of a digital broadcast multimedia network, the method comprising:

retrieving a point-to-point communication address for said receiver or decoder;

transferring a determined message for a determined receiver or decoder from the message administration service to a point-to-point communication system that is operatively connected to the receiver or decoder and is distinct from the digital broadcast multimedia network, wherein the point-to-point communication system is a mobile phone network, and wherein the determined message comprises access rights pertaining to the reception of data by the digital broadcast multimedia network;

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

generating a signal of availability at the receiver, triggering for emission of the determined message; and

upon reception of the signal of availability, emitting the determined message to the receiver;

retrieving, at the determined receiver or decoder, the determined message from the point-to-point communication system; and

loading the determined message into the receiver or decoder and updating the access rights related to the reception of data by the digital broadcast multimedia network.

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

receiving the determined message at the receiver; and

buffering the determined message at the receiver.

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

generating a confirmation of receipt at the receiver; and

emitting the confirmation of receipt to the emitter point.

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

generating a confirmation of receipt at the receiver; and

emitting the confirmation of receipt to the emitter point.

5. The method according to claim 4, in which the confirmation of receipt comprises at least one of a plurality of items of additional information selected from the group consisting of a status of the receiver or decoder, a status of a daughter smartcard used with the receiver or decoder, and a version number of an element of the receiver or decoder.

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

extracting the at least one item of additional information from the confirmation of receipt; and

evaluating the at least one item of additional information to determine a legal status of the receiver or decoder.

7. The method according to claim 1, wherein the message administration service is included as part of a Subscriber Authorization System.

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

receiving the determined message at the receiver; and

buffering the determined message at the receiver.

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

generating a confirmation of receipt at the receiver; and

emitting the confirmation of receipt to the emitter point.
