Abstract

A communication system 10 includes a head end 12 that generates a device list with channel or content authorizations. The head end communicates the list to a system gateway 26 . The gateway 26 receives the list. A plurality of user devices 28 is coupled to the gateway 26 . A first device of the plurality of user devices generates a channel or content request at the system gateway. The gateway 26 compares the channel or content authorizations from the list to the channel request from the first user device and communicates to the first user device a channel or content corresponding to the channel request in response to comparing. Thus, authorized users are able to receive the channel or content in response to the list. The list may be generated at a subscriber information module 52 and communicated with the content or channel through a satellite 18 or through a communication network 50.

First claim

What is claimed is:

1. A method of communicating content to a plurality of user devices in a multiple dwelling unit system having a multiple dwelling unit system gateway located in a multiple dwelling unit comprising:
generating a user list having content authorizations for each user device of the multiple dwelling unit system associated with the multiple dwelling unit system gateway at a conditional access system located remotely from the multiple dwelling unit system gateway, said user list generated in response to information from a subscriber information module associated with the conditional access system;
communicating the user list to the multiple dwelling unit system gateway from the conditional access system;
communicating content to the multiple dwelling unit system gateway;
receiving a content request at the multiple dwelling unit system gateway from a first user device of the plurality of user devices;
comparing the content authorizations from the user list to the content request from the user device at the multiple dwelling unit system gateway; and
communicating content to the first user device corresponding to the content request in response to comparing.

2. A method as recited in claim 1 further comprising when the content request is not on the list, preventing communication of the content to the first user device.

3. A method as recited in claim 1 wherein communicating content is performed when the content associated with the content request is in the user list.

4. A method as recited in claim 1 wherein communicating the user list comprises communicating the user list through a satellite.

5. A method as recited in claim 1 wherein communicating the content comprises communicating the content through a satellite.

6. A method as recited in claim 1 wherein communicating the user list comprises communicating the user list through a terrestrial link.

7. A method as recited in claim 1 wherein communicating the content comprises communicating the content through a terrestrial link.

8. A method as recited in claim 1 wherein communicating the user list comprises communicating the user list through a terrestrial link and wherein communicating the content comprises communicating the content through a satellite.

9. A method as recited in claim 1 wherein the user comprises an identifier and the user list comprises the identifier.

10. A method as recited in claim 1 wherein the user devices comprise multiple dwelling unit devices.

11. A method as recited in claim 9 wherein the identifier comprises an IP address.

12. A method of communicating channels to a plurality of user devices in a multiple dwelling unit system having a multiple dwelling unit system gateway located in a multiple dwelling unit comprising:
generating a user list having channel authorizations for each user device of the multiple dwelling unit system gateway at a conditional access system located remotely from the system gateway, said user list generated in response to information from a subscriber information module associated with the conditional access system;
communicating the user list to the multiple dwelling unit system gateway from the conditional access system;
communicating the channels to the multiple dwelling unit system gateway;
receiving a channel request at the multiple dwelling unit system gateway from a first user device from the plurality of user devices;
comparing the channel authorizations from the list to the channel request from the user at the multiple dwelling unit system gateway; and
communicating to the first user device a channel corresponding to the channel request in response to comparing.

13. A method as recited in claim 12 further comprising when the channel request is not on the list, preventing communication of the channel to the first user device.

14. A method as recited in claim 12 wherein communicating a channel is performed when the channel associated with the channel request is in the user list.

15. A method as recited in claim 12 wherein communicating the user list comprises communicating the user list through a satellite.

16. A method as recited in claim 12 wherein communicating the channels comprises communicating the channels through a satellite.

17. A method as recited in claim 12 wherein communicating the user list comprises communicating the user list through a terrestrial link.

18. A method as recited in claim 12 wherein communicating the channels comprises communicating the channels through a terrestrial link.

19. A method as recited in claim 12 wherein communicating the user list comprises communicating the user list through a terrestrial link and wherein communicating the channels comprises communicating the channels through a satellite.

20. A method as recited in claim 12 wherein the user comprises an identifier and the user list comprises the identifier.

21. A method as recited in claim 12 wherein the plurality of user devices comprise multiple dwelling unit devices.

22. A method as recited in claim 20 wherein the identifier comprises an IP address.

23. A system for distributing content to a multiple dwelling unit system gateway located in a multiple dwelling unit comprising:
a conditional access system generating a user list having content authorizations for each user device of the multiple dwelling unit system associated with the multiple dwelling unit system gateway, said user list generated in response to information from a subscriber information module associated with the conditional access system and communicating the user list and content to the system gateway;
the multiple dwelling unit system gateway, located remotely from and in communication with the conditional access system, receiving the user list and content;
a plurality of user devices coupled to the multiple dwelling unit system gateway forming the multiple dwelling unit system with the system gateway, a first user device of said plurality of user devices generating a content request and communicating the request to the multiple dwelling unit system gateway;
said multiple dwelling unit system gateway comparing the content authorizations from the user list to the content request from the first user device and communicating content to the first user device corresponding to the content request in response to comparing.

24. A system as recited in claim 23 wherein the multiple dwelling unit system gateway, when the content request is not on the user list, prevents communication of the content to the first user device.

25. A system as recited in claim 23 wherein the multiple dwelling unit system gateway communicates a channel when the channel associated with the content request is in the user list.

26. A system as recited in claim 23 further comprising a satellite in communication with the multiple dwelling unit system gateway and the satellite and conditional access system communicating the user list to the multiple dwelling unit system gateway.

27. A system as recited in claim 23 further comprising a terrestrial communication network in communication with the gateway and the conditional access system communicating the user list to the multiple dwelling unit system gateway.

28. A system as recited in claim 23 further comprising a satellite in communication with the system gateway and the conditional access system communicating the user list an
