Abstract

A method and apparatus is provided for coordinating devices in a federated network of devices. A server may determine policies for coordinating the devices and may send messages to devices in the federated network for providing a service. The policies for providing the service among the federated devices may be based on properties of the devices or relative locations of the devices. For example, the federated devices may provide media data and control of the media data to a user. Provision of the media data and/or control of the media data may change from one device to another in the federated network based on policies from the server.

Claims

1. A method for coordinating a service among a plurality of devices comprising:

determining a policy for coordinated operation of the plurality of devices in delivery of the service;

coordinating the service among the plurality of devices based on the policy.

2. The method of claim 1 wherein the step of determining the policy includes:

identifying a priority value of each of the devices based on a device property;

determining a policy for delivery of the service based on the relative value of the priority value of each of the devices.

3. The method of claim 2 wherein the step of identifying a priority value includes:

receiving a property of a device from the device;

assigning a priority value to each of the devices based on the property received from a corresponding device.

4. The method of claim 3 wherein the property includes at least one of device capability, availability, user preference, location, identity, trust level, and size.

5. The method of claim 4 wherein the step of determining a policy includes determining a distance between a first device and a second device, the first device providing the service.

6. The method of claim 5 wherein the distance between the first device and the second device is less than or equal to a first predetermined threshold value.

7. The method of claim 6 wherein the step of coordinating the service includes providing the service on the second device.

8. The method of claim 6 wherein the distance between the first device and the second device is less than or equal to a second predetermined threshold value, the second predetermined threshold value being less than the first predetermined threshold value.

9. The method of claim 8 wherein the step of coordinating the service includes providing the service on the second device and providing control of the service on the second device.

10. The method of claim 1 wherein the service comprises providing media data.

11. The method of claim 1 wherein the step of coordinating the service includes transmitting a message to each device in the plurality of devices, the message causing agreement in providing the service between the devices in the plurality of device.

14. The method of claim 1 further comprising transcoding data for the devices.

15. The method of claim 1 wherein the service is providing media data and the step of determining the policy includes:

tracking a location of a first device and a second device in the plurality of devices;

identifying a priority value of the first device and the second device, each priority value being based on the tracked location of a corresponding device;

assigning the corresponding priority value to each of the first device and the second device based on a relative location of the first and second device.

16. The method of claim 15 wherein the relative location of the first and second device includes a distance between the first and second devices being less than a first predetermined location and wherein the coordinating step includes at least one of changing from providing the service to the first device to providing the service to the second device and changing control of providing the service from the first device to the second device.

17. The method of claim 1 further comprising:

receiving a request from a device to participate in coordinating the service among the plurality of devices; and

authenticating the device;

wherein the device is capable of participating in coordinating the service among the plurality of devices after the authenticating step and wherein the authenticating includes identifying the device as permitted to participate in the coordination by at least one of the devices in the plurality of devices.

12. The method of claim 111 wherein the message causes providing the service to change from a first device in the plurality of devices to a second device in the plurality of devices.

13. The method of claim 12 wherein the message further causes control of providing the service to change from the first device to the second device.

18. An apparatus for coordinating delivery of a media service among a plurality of devices in a federated network, the apparatus comprising:

a policy correlator for determining a policy for coordinating the plurality of devices in one of delivering and controlling the media service; and

a management module for coordinating one of delivery and control of the media service among the plurality of devices based on the policy.

19. The apparatus of claim 18 further comprising a device tracker for determining relative locations of the devices in the federated network, the policy correlator further determining the policy based on a distance between the devices in the federated network, and the management module causing a device in the plurality of devices to one of display and control the media service based on the distances between the devices.

20. The apparatus of claim 18 wherein the policy correlator determines the policy based on corresponding priority values assigned to the devices in the plurality of devices, the priority values based on corresponding device properties, and wherein the management module coordinates the device associated with a highest value of priority value to provide the media service.
