Abstract

A method for the processing of control signals within an audiovisual network comprises at least one element (20) liable to send a digital command signal to at least one peripheral (181, 182), called an analog peripheral, designed to receive analog commands. The processing method implements, in a conversion device (241, 242), a conversion (92) of the digital command signal into at least one of the analog commands, said conversion being selectively configured as a function of said peripheral.

smart cards;

magnetic carriers; and

optical carriers.

7. A method according to claim 2, wherein said conversion device implements a step to verify the validity of said digital command signal as a function of said piece or pieces of configuration information.

8. A method according to claim 1, wherein said conversion device is independent of said audiovisual network element or elements and of said analog peripheral or peripherals.

9. A method according to claim 1, comprising a step for the storage of at least one piece of conversion information representing a set of commands accepted by said peripheral.

10. A method according to claim 9, wherein said pieces of conversion information are transmitted preliminarily by one of said elements of the network to said conversion device.

11. A method according to claim 9, comprising a step for the reading, by said conversion device, of said piece or pieces of configuration information on a detachable data carrier.

12. A method according to claim 1, wherein said digital command signal is of an IEEE 1394 type.

13. A method according to claim 12, comprising a step for the storage of data representing a configuration associated with said peripheral in a directory of said conversion device, said directory being compatible with the ConfigROM IEEE 1394 format.

14. A method according to claim 1, wherein the analog command signal is of a wireless type.

15. A method according to claim 1, wherein the analog command signal is of an infrared type.

16. A method according to claim 1, wherein pieces of data associated with said analog command signal are sent to said peripheral on the same transmission carrier.

17. A method according to claim 1, wherein pieces of data associated with said analog command signal are sent to said peripheral on a distinct transmission carrier.

18. A method according to claim 1, wherein said peripheral belongs to the group comprising:

camcorders;

television sets;

video recorders;

optical carrier readers; and

set-top boxes.

39. A computer program product, comprising sequences of instructions adapted to the implementation of a method for the processing of command signals according to claim 1, when said program is executed on a computer.
