Abstract

A method and apparatus is provided for managing a plurality of devices in a federated network and a sub-network within the federated network. The devices in the sub-network may have a functional capability of performing a function associated with the federated network. For example, the federated network may include devices for providing data content such as media content and the sub-network may include devices for controlling the presentation of the data content. In addition, a constellation of devices is provided that may share data content such as media data. At least some of the devices in the constellation may form a sub-network.

Claims

1. A method of managing a plurality of devices in a federated network comprising:

forming a federated network comprising a plurality of devices; and

federating a sub-network of devices within the federated network comprising at least a portion of the plurality of devices,

wherein the devices in the sub-network of devices have a capability of performing a function associated with the federated network.

2. The method of claim 1 wherein the sub-network comprises at least one device of the plurality of devices, the at least one device including a functional capability corresponding to a function of the sub-network.

3. The method of claim 1 wherein the devices in the federated network not included in the sub-network of devices lack the capability of performing the function associated with the federated network.

4. The method of claim 1 wherein the step of forming the sub-network of devices includes:

receiving a message from a device in the plurality of devices, the message including an indication of capabilities of the device; and

selecting the device for the sub-network based on the message.

5. The method of claim 4 wherein the step of selecting the device includes:

comparing the indicated capability of the device in the message with the function associated with the federated network;

determining a match between the indicating capability of the device and the function associated with the federated network; and

selecting the device for the sub-network.

6. The method of claim 1 wherein the devices in the federated network share content.

7. The method of claim 6 wherein the function associated with the federated network comprises control of the delivery of the content.

8. The method of claim 7 wherein only the devices in the sub-network perform the function.

9. The method of claim 7 wherein media data is provided by a first device in the plurality of devices.

10. The method of claim 9 wherein the first device moves to within a predetermined distance of a second device in the plurality of devices and wherein the second device in the plurality of devices provides the media data when the first device is within the predetermined distance of the second device.

11. The method of claim 9 wherein the first device moves to within a predetermined distance of a second device in the plurality of devices and wherein delivery of the media data changes from the first device to the second device based on the predetermined distance.

12. The method of claim 9 wherein the sub-network of devices includes the first device.

13. The method of claim 12 wherein the first device moves to within a predetermined distance of a second device in the plurality of devices and wherein delivery of the media data changes from the first device to the second device based on the predetermined distance.

14. The method of claim 13 wherein the first device controls the delivery of the media data after the first device moves to within the predetermined distance of the second device.

15. The method of claim 14 wherein the second device is outside of the sub-network of devices.

16. The method of claim 9 wherein the devices in the plurality of devices receive metadata corresponding to the media data.

17. The method of claim 1 wherein the step of federating a sub-network of devices includes forming at least a first plurality of sub-networks of devices and a second plurality of sub-network of devices, each of the devices in each of the first and second pluralities of sub-networks of devices comprising devices selected from the plurality of devices of the federated network.

18. The method of claim 17 wherein a first sub-network of devices contains a first function and a second sub-network of devices contains a second function, and wherein each of the first and second sub-networks of devices federates independently.

19. A constellation of devices configured to enable devices to automatically join the constellation, wherein the devices participate in the constellation according to their capabilities as communicated within the constellation.

20. The constellation of claim 19 wherein a first device plays and controls media data and wherein the first device federates with a second device and the second device, responsive to the federation, plays the media data, the first device controlling the media data after federation.
