Abstract

The present invention relates to a process for distributing audiovisual documents transmitted from a broadcasting office. The office broadcasts the documents to fixed distribution facilities. The users approach the facility and with the aid of a portable terminal request the downloading by radio of the documents that they have selected. Once downloaded, the users can connect the portable terminal to their home so as to reproduce the documents recorded in the terminal. The present invention also relates to the distribution facility and the portable terminal making it possible to store the document.

Claims

1. A process for distributing audiovisual documents transmitted from a broadcasting office;

wherein it comprises the following steps;

entry of a download command at the level of a portable terminal, and downloading by radio of the document from a fixed device to the memory of the portable terminal,

connection of the portable terminal to a domestic installation so as to reproduce the document within said domestic installation.

2. The process for distributing documents as claimed in claim 1;

wherein the downloading of the document into the portable terminal comprises the following steps;

transmission by the fixed device of a signal proposing the downloading of at least one document,

selection at the level of the portable terminal of at least one document identified in the signal received,

transmission by the fixed device and reception at the level of the portable terminal of at least one document,

storage of the document selected at the level of the portable terminal.

3. The process for distributing documents as claimed in claim 2;

wherein the transfer is conditioned by the proper running of a step of payment of a price associated with the document selected and stored in the fixed device.

4. The process for distributing documents as claimed in claim 2, wherein it comprises a step of metering the number of reproductions at the level of the domestic installation, and a step of payment of a sum calculated as a function of this number.

5. The process for distributing documents as claimed in claim 1;

wherein it comprises a step of metering the documents downloaded by the fixed device.

6. The process for distributing documents as claimed in claim 5;

wherein it comprises a step of deletion of a document within the fixed device, said step of deletion being triggered when the downloading counter associated with this document has reached a certain value.

7. The process for distributing documents as claimed in claim 5;

wherein it comprises a step of deletion of a document within the fixed device, said step of deletion being triggered when the number of downloads per unit time is less than a determined value.

8. The process for distributing documents as claimed in claim 1;

wherein the document is stored enciphered in the fixed device, and in that it comprises, prior to the downloading of a document into a terminal, a step of deciphering this document and a step of enciphering the document with the aid of a key associated with the terminal intended to receive the document.

9. The process for distributing documents as claimed in claim 1;

wherein the selecting of a document is performed by a step of entering an identifier at the level of the portable terminal, and a step of sending this identifier within the fixed device.

10. The process for distributing documents as claimed in claim 1;

wherein it comprises a step of display at the level of the terminal of the documents available within the fixed device.

11. A portable terminal comprising a central unit, a means of storing at least one audiovisual document, a means of communication by connection with another apparatus or a network;

wherein it furthermore comprises a means of wireless communication for the receiving of at least one document download signal, a means of entering a command making it possible to activate the reception of said document with the aid of the wireless communication means, the storage means storing the document received, the reproduction of at least one stored document being performed with the aid of the means of communication via a connection.

12. The portable terminal as claimed in claim 11;

wherein it comprises a means of making a payment corresponding to a sum associated with the identifier of the document.

13. The portable terminal as claimed in claim 11;

wherein it comprises a means of metering the reproductions of at least one document recorded in the storage means, and a means of transmitting the number associated with the metering means.

14. The portable terminal as claimed in claim 11;

wherein it comprises a means of deciphering associated with a deciphering key specific to the terminal, said deciphering means being activated upon the reproduction of the document recorded in the storage means.

15. The portable terminal as claimed in claim 11;

wherein the wireless communication means receives a list of identifiers of documents, the means of entry receiving a command for selecting at least one identifier of a document to be downloaded, and the wireless communication means transmitting a signal comprising the identifier of the document to be downloaded and a data item specific to the terminal.

16. The portable terminal as claimed in claim 11;

wherein it comprises a means of displaying the list of identifiers.

17. The portable terminal as claimed in claim 11;

wherein it comprises a chip card reader allowing a payment to be validated and/or the downloading of the document and/or the reproduction of the document to be made secure.

18. A fixed device for downloading audiovisual documents, comprising a central unit, a means of storing at least one audiovisual document;

wherein it comprises a means of communication by radio receiving a signal for downloading from an apparatus situated in immediate proximity and sending in response the document specified in the download signal.

19. The fixed device for downloading audiovisual documents as claimed in claim 18;

wherein the means of communication by radio transmits a list of identifier of the documents stored in the memory, receives a download request comprising an identifier of at least one document and an identifier of a terminal, and transmits the document identified in the request.

20. The fixed device for downloading audiovisual documents as claimed in claim 19;

wherein the document is transmitted in enciphered form, the device comprising a means of enciphering the document with the aid of an enciphering key associated with the identifier of the terminal.

21. The fixed device for downloading audiovisual documents as claimed in claim 18;

wherein the transfer of the document is conditioned by a payment.

22. The fixed device for downloading audiovisual documents as claimed in claims 18;

wherein it comprises a means of metering the downloads associated with at least one document, and a means of deletion of this document from the memory, said means being activated when the value of the means of metering of downloading associated with this document has reached a predetermined value.

23. The fixed device for downloading audiovisual documents as claimed in claim 18;

wherein it comprises a means of metering the downloads associated with at least one document, and a means of deletion of this document from the memory, said means being activated when the number of downloads per unit time is less than a determined value.
