Abstract

A method and system includes a central location 100 registering a portable device 36 with a central location 100 and generating a conditional access signal corresponding to the portable device 36 in response to registering and transmitting the conditional access signal to a storage device controller. A set top box or storage device controller 28 receives the conditional access signal and enables a transfer of a file. The portable device 36 receives the file when coupled to the set top box in response to the conditional access signal.

Claims

1. A method comprising:

storing a unique identifier of a portable device in a memory associated with a storage device controller to form a stored identifier;

coupling the portable device to the storage device controller;

communicating an identifier from the portable device to the storage device controller;

comparing the identifier from the portable device with the stored identifier in the memory; and

enabling a transfer of a file in response to the identifier.

2. A method as in claim 1 disabling the transfer of the file in response to a non-equal result in the step of comparing.

3. A method as in claim 1 wherein prior to storing a serial number, transmitting the serial number to the storage device controller through a satellite.

4. A method as in claim 3 wherein prior to transmitting, associating the serial number to a storage device controller.

5. A method as in claim 3 wherein prior to transmitting, associating the serial number to a plurality of storage device controllers.

6. A method as in claim 3 wherein prior to transmitting associating the serial number to a plurality of storage device controllers associated with a single account.

7. A method as in claim 1 wherein the storage device comprises a digital video recorder.

8. A method as in claim 1 wherein the portable device comprises a portable media player.

9. A method as in claim 1 wherein the portable device comprises a personal computer.

10. A method comprising:

registering a portable device with a central location;

generating a conditional access signal corresponding to the portable device in response to registering;

communicating the conditional access signal to a storage device controller;

coupling the portable device to the storage device controller; and

communicating files to the portable device in response to the conditional access signal.

11. A method as in claim 10 wherein communicating the conditional access signal comprises communicating the conditional access signal through a satellite.

12. A method as in claim 10 wherein communicating the conditional access signal comprises communicating the conditional access signal through a terrestrial-based system.

13. A method as in claim 12 wherein the terrestrial-based system comprises a public service telephone network.

14. A method as in claim 10 wherein the conditional access signal comprises a seed signal.

15. A method as in claim 10 wherein the conditional access signal comprises a seed signal and a serial number signal.

16. A method as in claim 10 wherein the conditional access signal comprises a serial number signal.

17. A method as in claim 10 wherein the conditional access signal comprises a revocation list.

18. A method as in claim 10 wherein the conditional access signal comprises a seed signal, a serial number signal corresponding to a serial number and a revocation list, and wherein communicating files to the portable device is performed in response to the serial number not on the revocation list.

19. A method as in claim 10 wherein the storage device comprises a digital video recorder.

20. A method as in claim 10 wherein the portable device comprises a portable media player.

21. A method as in claim 10 wherein the portable device comprises a personal computer.

22. A system comprising:

a central location registering a portable device with a central location, generating a conditional access signal corresponding to the portable device in response to registering and transmitting the conditional access signal to a storage device controller;

a set top box or storage device controller receiving the conditional access signal and enabling a transfer of a file; and

a portable device receiving the file when coupled to the set top box in response to the conditional access signal.

23. A system as recited in claim 22 wherein the set top box comprises a satellite television set top box and further comprising a storage device is associated with the satellite television set top box, said storage device controller in communication with the storage device.

24. A system as recited in claim 22 further comprising an interface coupling the set top box or storage device controller to the portable device.

25. A system as recited in claim 24 wherein the interface comprises a wired interface.

26. A system as recited in claim 25 wherein the wired interface comprises a USB interface.

27. A system as recited in claim 25 wherein the wired interface comprises an Ethernet interface.

28. A system as recited in claim 24 wherein the interface comprises a wireless interface.

29. A system as recited in claim 28 wherein the wireless interface comprises a local area network interface.
