[0023] System Overview

[0024] The same reference symbols will be used throughout the specification to refer to the same elements in the drawings.

[0025] Figure 2 contains a simplified illustration of a digital television system. On the broadcast station side, the signal compression system 100 compresses a digital signal stream (not shown) and outputs the compressed signal stream to the multiplexer 101 . An example of compression is the well-known MPEG-2 standard, which is widely used in digital television services. Multiplexer 101 produces a compressed signaling stream for transmission to a user with receiver decoder 102 . The transport stream is transmitted using an antenna to a satellite 104 and then broadcast to a receiving antenna 105 connected to the input of a receiver decoder 102 . Figure 2 illustrates a satellite transmission system, but any other means of transporting the transport stream from the broadcaster side to the user can be used.

Abstract

The present invention provides a method for distributing a message from a message administration service (204) to a subscriber receiver decoder (202) 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 (601, 600; 700) distinct from the multimedia network. A destination point address of a receiver in the point to point communication system (701) is determined, corresponding to the determined receiver decoder. The determined message is buffered in the point to point communication system, and retrieved (709) at the determined receiver decoder from the receiver.

Description

technical field [0001] The invention relates to the management of access right in digital multimedia network. Background technique [0002] Figure 1 briefly illustrates an example of a digital multimedia network. The network 1 is used to exchange information between one or more broadcast operators represented by blocks 2 and 3 and users represented by blocks 4 to 6 . The network can be, for example, a terrestrial television broadcasting network in which broadcast operators transmit signals received by subscribers via antennas. Another example of a network may be a cable network or a satellite transmission network. [0003] Each broadcast operator can broadcast several digital multimedia services to users. Multimedia services may include, for example, television programs, radio programs, and interactive applications. [0004] Each user has a receiver-decoder for receiving multimedia services and in some cases processing the received multimedia services in order to timely ...
