Abstract

A user may purchase in a retail outlet a host device for receiving cable services. The cable operator needs to provide a point-of-deployment (POD) module for insertion into the host device to realize out-of-band communications, and provide conditional access to premium subscription channels. Security measures are implemented to detect removal of the host device from its connection to a broadband communications system. If its removal is unauthorized, the service area in which the host device is located may be identified when it is reconnected to the system. In addition, a transmission device in the host device may be activated to transmit detectable signals to help recover the host device.

Claims

1. A system for tracking a device connectable to a communications network through one of a plurality of nodes, the nodes being associated with respective ones of service areas, the device being identifiable by identifying data, the system comprising:

an interface for receiving, through a first node, a request for connection of the device to the communications network after the device has been connected to the communications network through a second node, the request including information concerning the device; and

a server for determining whether at least part of the information corresponds to the identifying data, the first node being identified through which the request is received if it is determined that at least part of the information corresponds to the identifying data,

whereby the device is presumed to be located in the service area associated with the first node.

2. The system according to claim 1, further comprising a mechanism for causing the device to generate a detectable signal to facilitate locating the device within the service area associated with the first node.

3. The system according to claim 1, wherein the detectable signal contains information for identifying the device.

4. The system according to claim 1, wherein the communications network includes a two-way multichannel delivery network.

5. The system according to claim 4, wherein the delivery network includes a cable TV network.

6. The system according to claim 5, wherein the cable TV network includes an HFC cable network.

7. The system according to claim 5, wherein the device receives programming content from the communications network.

8. The system according to claim 7, wherein the device includes a host device having an interface for coupling with a POD module for providing conditional access to selected programming content.

9. The system according to claim 8, wherein the selected programming content is selected by the system.

10. The system according to claim 8, wherein the selected programming content includes VOD content.

11. The system according to claim 1, wherein the identifying data includes a serial number pre-assigned to the device.

12. Apparatus for receiving programming content from a communications network, the apparatus being identifiable by identifying data, the apparatus comprising:

an interface for coupling with a device for effecting a communication to a server through the communications network, the communication including the identifying data, and an address of the device within the communications network; and

a transmission mechanism, a message being sent to the address if the apparatus has been removed from a connection to the communications network without authorization, the message causing the transmission mechanism to generate a detectable signal for locating the apparatus.

13. The apparatus according to claim 12, wherein the address includes an Internet protocol (IP) address.

14. The apparatus according to claim 12, wherein the address includes a media access control (MAC) address.

15. The apparatus according to claim 12, wherein the identifying data includes a serial number pre-assigned to the apparatus.

16. The apparatus according to claim 12, wherein the detectable signal contains information concerning a serial number pre-assigned to the apparatus.

17. The apparatus according to claim 12, further comprising a modem for modulating signals representing the communication.

18. The apparatus according to claim 12 comprising an entertainment unit.

19. The apparatus according to claim 18, wherein the entertainment unit includes a TV unit.

20. A method for tracking a device connectable to a communications network through one of a plurality of nodes, the nodes being associated with respective ones of service areas, the device being identifiable by identifying data, the method comprising:

receiving, through a first node, a request for connection of the device to the communications network after the device has been connected to the communications network through a second node, the request including information concerning the device; and

determining whether at least part of the information corresponds to the identifying data, the first node being identified through which the request is received if it is determined that at least part of the information corresponds to the identifying data,

whereby the device is presumed to be located in the service area associated with the first node.

21. The method according to claim 20, further comprising causing the device to generate a detectable signal to facilitate locating the device within the service area associated with the first node.

22. The method according to claim 20, wherein the detectable signal contains information for identifying the device.

23. The method according to claim 20, wherein the communications network includes a two-way multichannel delivery network.

24. The method according to claim 23, wherein the delivery network includes a cable TV network.

25. The method according to claim 24, wherein the cable TV network includes an HFC cable network.

26. The method according to claim 24, wherein the device receives programming content from the communications network.

29. The method according to claim 27, wherein the selected programming content includes VOD content.

30. The method according to claim 20, wherein the identifying data includes a serial number pre-assigned to the device.

31. A method for use in an apparatus for receiving programming content from a communications network, the apparatus including a transmission mechanism and being identifiable by identifying data, the method comprising:

providing an interface for coupling with a device for effecting a communication to a server through the communications network, the communication including the identifying data, and an address of the device within the communications network; and
