Abstract

The process comprises the steps consisting in:

(a) receiving data in a first device, the data containing at least one anticopy protection system identifier;

(b) verifying whether the first device is connected to a data recording device by a digital bus; and in case of positive verification:

(c) verifying whether the first device comprises a module implementing an anticopy protection system whose identifier is included in the data; and in case of positive verification:

(d) offering a user access to the data according to a first mode of access (PPVR) authorizing the recording of the data; and

in case of negative verification in step (b) or step (c):

(e) offering a user access to the data according to a second mode of access (PPV) not authorizing the recording of the data.

Claims

1. Process for transmitting data representative of a content comprising the steps consisting in:

(a) receiving data in a first device, said data containing at least one anticopy protection system identifier;

(b) verifying whether the first device is connected to a data recording device by a digital bus; and

in case of positive verification;

(c) verifying whether the first device comprises a module implementing an anticopy protection system whose identifier is included in said data; and

in case of positive verification;

(d) offering a user access to said data according to a first mode of access authorizing the recording of said data; and

in case of negative verification in step (b) or step (c);

(e) offering a user access to said data according to a second mode of access not authorizing the recording of said data.

2. Process according to claim 1, furthermore comprising the step consisting, in case of positive verification in step (c):

(i) in verifying whether said anticopy protection system belongs to a first category of systems using a mode of protection specific to the digital bus connecting said first device to said recording device, and in case of positive verification;

(j) in verifying whether at least one recording device to which said first device is connected comprises a module implementing the same anticopy protection system;

step (d) being implemented in case of positive verification in step (j) or of negative verification in step (i);

and step (e) being implemented in case of negative verification in step (j).

3. Process according to claim 1, furthermore consisting, during step (d), in offering the user access to said data according to the second mode of access not authorizing the recording of the data.

4. Process according to one of claims 1 to 3, wherein an option of purchase of the data according to the first mode of access to said data is offered to the user after a presentation of the data to the user.

5. Process according to claim 1, wherein access to the data according to the first mode of access is offered in return for the payment of a price corresponding to a first amount included in a first field contained in said data.

6. Process according to claim 5, wherein access to the data according to the second mode of access is offered in return for the payment of a price corresponding to a second amount included in a second field contained in said data.

7. Process according to claim 6, wherein the second amount is less than the first amount.

8. Process according to claim 1, wherein the anticopy protection system identifier is included in a part of the received data which is protected by encryption or by authentication.

9. Process according to claim 1, wherein the data are broadcast, when the user selects the mode of access offered in step (d), with an associated state which is defined in a third field included in said data.
