Abstract

A local area network (504) for providing Media Provider control and user privacy when distributing media content to the local area network (504). The local area network (504) comprises media devices (510-514) and a proxy (528). The media devices (510-514) provide a description of the capabilities of the media devices (510-514) to a Media Provider (506) in response to receiving a query for the capabilities of the media devices (510-514) from the Media Provider (506). The media devices (510-514) also receive media content directed to the media devices (510-514) from the Media Provider (506). The media content includes content objects based on the capabilities of the media devices (510-514). The proxy (528) translates between generic device names known to the Media Provider (506) and physical device addresses corresponding to the media devices (510-514).

Claims

1. A local area network for providing Media Provider control and user privacy when distributing media content to the local area network, the local area network comprising:

a plurality of media devices configured to provide a description of the capabilities of the plurality of media devices to a Media Provider in response to receiving a query for the capabilities of the plurality of media devices from the Media Provider, and receiving media content directed to the plurality of media devices from the Media Provider, the media content including a plurality of content objects based on the capabilities of the plurality of media devices; and

a proxy configured to translate between generic device names known to the Media Provider and physical device addresses corresponding to the plurality of media devices.

2. The local area network of claim 1, further comprising a table associated with the proxy, the table including the generic device names and the physical device addresses.

3. The local area network of claim 2, wherein the table further includes capabilities of the plurality media devices.

4. The local area network of claim 1, wherein the plurality of media devices includes a video media device, an audio media device and a text media device.

5. The local area network of claim 4, wherein:

the proxy receives media content directed to the plurality of media devices from the Media Provider;

the media content is requested by a remote agent and includes a plurality of content objects; and

each content object is associated with a particular media device

6. The local area network of claim 1, wherein the network address corresponding to the local area network is concatenated with the generic device names.

7. The local area network of claim 1, wherein the proxy resides in a gateway or router.

8. The local area network of claim 1, wherein the proxy communicates with a wide area network that is based on an Internet Protocol

9. The local area network of claim 1, wherein:

the local area network is based on an Internet Protocol and uses private Internet Protocol addresses for the media devices; and

the proxy translates between the private Internet Protocol addresses of the local area network and the public Internet Protocol addresses of the wide area network.

10. The local area network of claim 1, wherein:

the local area network is based on a protocol other than an Internet Protocol; and

the proxy interconnects the wide area network that is based on an Internet Protocol to a technology used in the local area network.

11. A method of local area network for providing Media Provider control and user privacy when distributing media content to the local area network, the local area network including a plurality of media devices, the method comprising:

receiving a query for capabilities of the plurality of media devices from a Media Provider;

providing a description of the capabilities of the plurality of media devices to the Media Provider in response to receiving the query for the capabilities of the plurality of media devices;

receiving the media content directed to the plurality of media devices from the Media Provider, the media content including a plurality of content objects based on the capabilities of the plurality of media devices, each content object being associated with a particular media device; and

consuming the media content by engaging the plurality of content objects together, each content object being engaged at the particular media device associated with the content object.

12. The method of claim 11, further comprising translating between generic device names known to the Media Provider and physical device addresses corresponding to the plurality of media devices.

13. The method of claim 12, wherein sharing a network privacy key among a remote agent and a plurality of media devices includes sharing the network privacy key with the remote agent having certificate information associated with the plurality of media devices.

14. The method of claim 13, wherein sharing the network privacy key with the remote agent includes sharing the network privacy key with the remote agent having the digital security certificates of the plurality of media devices or a list identifying the digital security certificates of the plurality of media devices.

15. The method of claim 11, wherein the media content is requested by a remote agent.

16. The method of claim 11, wherein receiving content objects directed to the plurality of media devices from the Media Provider includes receiving the content objects in which each content object is customized for a corresponding media device.

17. The method of claim 11, wherein consuming the media content by engaging a content object at the particular media device includes consuming the content object at the particular media device for which the content object was customized.

18. The method of claim 11, wherein receiving content objects directed to the plurality of media devices from the Media Provider includes receiving a video content object directed to a video media device, an audio content object directed to an audio media device and a text content object directed to a text media device.

19. The method of claim 11, further comprising sharing a network privacy key among the remote agent and the plurality of media devices.

20. The method of claim 11, further comprising:

receiving right objects associated with the content objects from the remote agent, the rights objects being encrypted based on the network privacy key;

decrypting the rights objects using the network privacy key; and

decrypting the content objects using the decrypted rights objects corresponding to the content objects.
