Abstract

An electronic device is disclosed. According to at least one embodiment, the device includes a front-end module having at least one front-end connector, adapted to be connected to a cable adapted for receiving electrical signal, a reception module adapted to receive an electrical signal from the front-end connector, a back-end module configured to process an electrical signal, an interfacing module comprising at least an isolation module adapted to transmit, to the back-end module, an electrical signal received from the front-end module.

Claims

1. An electronic device, comprising:

a front-end module comprising;

at least one front-end connector adapted to be connected to a first cable adapted to receive at least one electrical signal and for transmitting Direct Current, said front-end connector being adapted to be connected to a second cable only adapted for receiving at least one electrical signal;

at least one control module adapted to supply Direct Current to said front-end connector according to at least one command signal transmitted by a control processing unit;

a reception module adapted to receive at least one electrical signal from said front-end connector;

a back-end module configured to process at least one electrical signal;

an interfacing module comprising at least an isolation module adapted to transmit, to said back-end module, at least one electrical signal received from said front-end module.

2. The Electronic device according to claim 1 wherein said electronic device is adapted to operate in a first mode, where said Direct Current is supplied to said front-end connector, and to a second mode, where no Direct Current is supplied to said front-end connector, according to said command signal.

3. The electronic device according to claim 1, wherein said isolation module is adapted to prevent a Direct Current signal continuity and/or a connection of earth ground of said front end and back-end modules.

4. The electronic device of claim 1, wherein:

said back-end module comprises at least one back-end connection module adapted to receive Direct Current from a Direct Current line; and

said interfacing module comprises at least one isolated DC current supplying module, adapted to be connected to said back-end connection module and to transmit Direct Current to said control module.

5. The electronic device of claim 1, wherein said control module is adapted to transmit at least one control signal to said front-end connector.

6. The electronic device of claim 1, wherein said electronic device comprises a switch adapted to command said control module via said control processing unit.

7. The electronic device of claim 6, wherein said switch is accessible at least partially from an outer casing of the electronic device.

8. The electronic device of claim 6, wherein said switch is adapted to be manually actuated.

9. The electronic device of claim 1, wherein said electronic device comprises a user interface module adapted to command said control module via said control processing unit.

10. The electronic device of claim 1, wherein said control module comprises at least one Low Noise Bloc (LNB) control module.

11. The electronic device of claim 1, wherein said cable is adapted to provide an interface to a Single Master Antenna Television (SMATV) network.

12. The electronic device of claim 1, wherein said cable is adapted to provide an interface to a terrestrial network.

13. The electronic device of any of claim 1, wherein said front-end module comprises at least one tuning and/or demodulating module.

14. The electronic device of any of claim 1, wherein said back-end module comprises at least one tuning and/or demodulating module.

16. The electronic device of claim 1, wherein the network is a collective network.

17. The electronic device of claim 1, wherein the network is an individual network, dedicated to a single private area.

18. The electronic device of claim 1, wherein said isolation module comprised in said connection device is a transformer comprising at least two windings.

15. The electronic device is suitable for receiving audiovisual programs via an interface suitable for receiving radio frequency signals over a cable network.

19. A method for processing an electrical signal, said method comprising:

receiving at least one electrical signal on at least one front-end connector of a first electronic device, said front-end connector being adapted to be connected to a first cable adapted for receiving at least one electrical signal and for transmitting Direct Current, said front-end connector being adapted to be connected to a second cable only adapted for receiving at least one electrical signal;

transmitting said received electrical signal through at least one communication path including at least one isolation module to at least one processing module of said first electronic device;

processing said electrical signal;

supplying Direct Current to said front-end connector according to at least one command signal transmitted by a control processing unit to at least one control module of said first electronic device.

20. The method according to claim 19, wherein said method comprises:

receiving said Direct Current from a Direct Current line;

transmitting said received Direct Current through a Direct Current supplying path not using said isolation module, to said control module of said first electronic device.
