Abstract

The present invention relates to a communication system comprising a recording and/or reproducing device (11) able to read a data carrier, and a first remote unit (12) comprising additional data for the data carrier. The recording and/or reproducing device (11) and the first remote unit (12) communicate via a network. The communication system comprises a second remote unit (13) able to authenticate a trusted recording and/or reproducing device, and to make the trusted recording and/or reproducing device access the additional data. A trusted recording and/or reproducing device is able to detect the presence of the data carrier in the recording and/or reproducing device and to authenticate said data carrier.

Claims

1. A communication method via a network between a recording and/or reproducing device (11) able to read a data carrier, and a first remote unit (12) comprising additional data for the data carrier, said method comprising the steps of:

detecting the presence of the data carrier in the recording and/or reproducing device and authenticating said data carrier, said steps being performed by a trusted recording and/or reproducing device,

authenticating a trusted recording and/or reproducing device, said step being performed by a second remote unit and being able to make the trusted recording and/or reproducing device access the additional data.

2. A communication system comprising a recording and/or reproducing device (11) able to read a data carrier, a first remote unit (12) comprising additional data for the data carrier, and a second remote unit able to authenticate a trusted recording and/or reproducing device and to make the trusted recording and/or reproducing device access the additional data, a trusted recording and/or reproducing device being able to detect the presence of the data carrier in the recording and/or reproducing device and to authenticate said data carrier, said device (11) and units communicating via a network.

3. A communication system as claimed in claim 2, which comprises a third remote unit (14) and wherein the second remote unit (13) is managed by a manufacturer of recording and/or reproducing devices (11), said third remote unit (14) communicating directly with second remote units (13) and with first remote units (12) via the network.

4. A communication system as claimed in claim 2, wherein the second remote unit is adapted to communicate directly with recording and/or reproducing devices (11) and with first remote units (12) via the network.

5. A communication system as claimed in claim 2, wherein the second remote unit and the first remote unit are the same entity.

6. A remote unit for communicating with a recording and/or reproducing device (11) able to read a data carrier, the remote unit comprising:

means for authenticating a trusted recording and/or reproducing device, a trusted recording and/or reproducing device being able to detect the presence of the data carrier in the recording and/or reproducing device and to authenticate said data carrier, and

means for enabling the trusted recording and/or reproducing device to access additional data corresponding to the data carrier.

7. A recording and/or reproducing device (11) able to read a data carrier, to communicate with a first remote unit (12) comprising additional data for the data carrier, and to communicate with a second remote unit able to authenticate the recording and/or reproducing device, said device comprising means for detecting the presence of the data carrier in the recording and/or reproducing device and means for authenticating said data carrier.
