Abstract

Methods and apparatus for perform association of stored content downloaded over a network with a unique identification. In one embodiment, the content is stored locally, and the association is performed in a secure manner using network or source-specific information (e.g., the organization identification or “orgID” of the bearer network or MSO). This association is used to ensure that the content stored on the playback device can be accessed for viewing only when the playback device is connected to the same network from which the content was obtained. Use of the orgID allows the content association and protection functionality to be implemented in existing networks with only minor software changes.

Claims

1. Consumer premises equipment (CPE) adapted for connection to a first content distribution network having a plurality of information sources associated therewith, and for receipt of content via said first network, said CPE comprising:

a processor;

a storage device in data communication with said processor; and

store at least a portion of said content on said storage device;

extract first information configured to identify a second network associated with said at least portion of said content;

request second information configured to identify said first network;

compare at least a portion of said second information configured to identify said first network to at least a portion of said first information configured to identify said second network to determine whether said first network and said second network comprise a same network;

when said first information configured to identify said second network and said second information configured to identify said first network indicate that said first network and said second network comprise said same network, allow playback of said content; and

when said first information configured to identify said second network and said second information configured to identify said first network indicate that said first network and said second network comprise different networks, disallow playback of said content.

2. The CPE of claim 1, wherein said plurality of instructions are further configured to interactively receive at least one first command from a user, and in response to said first command, cause said storage of said at least portion of said content on said storage device.

3. The CPE of claim 1, wherein said first information comprises a Multimedia Home Platform (MHP) 38-bit organization identifier, and at least one of said plurality of sources comprises a multi-systems or services operator (MSO).

4. The CPE of claim 1, wherein said first information is embedded in said content by at least one of said plurality of sources.

5. The CPE of claim 1, wherein said extraction of said first information is required in order to play back said content.

6. The CPE of claim 5, wherein said first information comprises encrypted information.

7. The CPE of claim 5, wherein said first information comprises an encrypted header which, when decrypted identifies said second network associated with said at least portion of said content in a string format.

8. The CPE of claim 2, wherein said computer application comprises a recording application, and said first command comprises a “

record”

command generated by said user via a remote unit.

9. The CPE of claim 1, wherein said storage comprises storage on a fixed medium.

10. The CPE of claim 1, wherein said first and second information each comprise organization identification (orgID) information.

11. The CPE of claim 1, wherein said plurality of instructions are further configured to log data relating to at least cases where said first information configured to identify said second network and said second information configured to identify said first network indicate that said first network and said second network comprise different networks, and said playback is disallowed.

12. A method of operating consumer premises equipment (CPE) in communication with a content distribution network, said method comprising:

receiving content at said CPE;

storing at least a portion of said content on a storage device in data communication with said CPE;

deriving a first identifier from at least said portion of said content, said first identifier being configured to designate at least one source network associated with said at least portion of said content;

based at least in part on said first identifier, determining whether said source network comprises a same network as said content distribution network, or a different network therefrom; and

based at least in part on said determination, authorizing said CPE to record said content when said source network and said content distribution network comprise said same network, and not authorizing said CPE to record said content when said source network and said content distribution network comprise different networks.

13. The method of claim 12, further comprising receiving at least one first command from a user, and in response to said first command, performing said act of storing.

14. The method of claim 12, wherein said first identifier comprises a Multimedia Home Platform (MHP) 38-bit organization identifier, and said at least one source network is associated with a multi-systems or services operator (MSO).
