Abstract

Media devices are connected to a network. Restrictive rights restrict how the media device can process restricted media content on the network. Information indicative of the restrictive rights associated with the network is stored on the network. A request is received to deliver restricted media content to a requested device, which lacks the right to process it. The stored information is used to determine which media device has the restrictive right to process the requested content, and an instruction is sent to that device. The processed content is then delivered from the determined device to the requesting device. A centralized embodiment of the network has a server connected to the media devices. Another embodiment of the network enables the media devices to obtain restricted media content suitable for the restrictive rights of the network from content providers.

Claims

1. A method of managing restricted media content with a server and a plurality of media devices, the server and the media devices connected to a network by a plurality of communication paths, wherein restrictive rights restrict how the media devices can process the restricted media content, the method comprising:

storing information at the server indicative of the restrictive rights associated with the media devices;

receiving a request at the server for delivery of restricted media content to a requested media device, wherein the requested media device lacks the restrictive right to process the requested media content;

determining from the information stored at the server which media device has the restrictive right to process the requested media content;

sending an instruction from the server to the determined media device to process the requested media content according to the restrictive right of the requested media content;

delivering the processed media content from the determined media device to the requested media device.

2. The method of claim 1, wherein the media devices are selected from the group consisting of a portable electronic device, a portable music player, a cellular communication device, a home entertainment system, a personal computer, and a vehicular entertainment system.

3. The method of claim 1, wherein the media content is selected from the group consisting of multi-media data, audio data, video data, cable broadcast data, radio broadcast data, satellite broadcast data, and television broadcast data.

4. The method of claim 1, wherein the restrictive right is selected from the group consisting of:

a format for restricted media content that a media device can process;

an encryption for restricted media content that a media device can decrypt;

a license for restricted media content that a media device can process;

a designation of whether a media device is authorized to process restricted media content;

a number of times that restricted media content can be processed by a media device; and

a length of time that restricted media content can be processed by a media device.

5. The method of claim 1, wherein the information stored at the server comprises information identifying a location of the restricted media content on the network, and wherein the act of determining further comprises:

determining the location of the requested media content on the network; and

transferring the requested media content from the location to the determined media device if the determined media device is not the location.

6. The method of claim 1, wherein the act of delivering comprises:

processing the restricted media content at the determined media device according to the restrictive right; and

sending the processed media content from the determined media device to the requested media device or to another media device for further processing before sending to the requested media device.

7. The method of claim 1, further comprising monitoring the media devices actively connected to the network to update the information at the server.

8. A method of managing restricted media content with a plurality of media devices connected to a network by a plurality of communication paths, wherein restrictive rights restrict how the media devices can process the restricted media content, the method comprising:

storing information indicative of the restrictive rights associated with the media devices;

receiving a request for delivery of restricted media content to a requested media device, wherein the requested media device lacks the restrictive right to process the requested media content;

determining from the stored information which media device has the restrictive right to process the requested media content;

instructing the determined media device to process the requested media content according to the restrictive right of the requested media content; and

delivering the processed media content from the determined media device to the requested media device.

9. The method of claim 8, wherein the media devices are selected from the group consisting of a portable electronic device, a portable music player, a cellular communication device, a home entertainment system, a personal computer, and a vehicular entertainment system.

10. The method of claim 8, wherein the media content is selected from the group consisting of multi-media data, audio data, video data, cable broadcast data, radio broadcast data, satellite broadcast data, and television broadcast data.

11. The method of claim 8, wherein the restrictive right comprises an indication selected from the group consisting of:

a format for restricted media content that a media device can process;

an encryption for restricted media content that a media device can decrypt;

a license for restricted media content that a media device can process;

a designation of whether a media device is authorized to process restricted media content;

a number of times that restricted media content can be processed by a media device; and

a length of time that restricted media content can be processed by a media device.

12. The method of claim 8, wherein the stored information comprises information identifying a location of the restricted media content on the network, and wherein the act of determining further comprises:

determining the location of the requested media content on the network; and

transferring the requested media content from the location to the determined media device if the determined media device is not the location.

13. The method of claim 8, wherein the act of delivering comprises:

processing the restricted media content at the determined media device according to the restrictive right; and

sending the processed media content from the determined media device to the requested media device or to another media device for further processing before sending to the requested media device.

14. The method of claim 8, further comprising sharing the stored information between the media devices actively connected to the network, wherein the acts of receiving the request, determining which media device, and instructing the determined media device are handled by one or more the active media devices.

15. A method of obtaining restricted media content from external sources of restricted media content for a plurality of media devices, the media devices connected to a network by a plurality of communication paths, wherein restrictive rights restrict how the media devices can process the restricted media content, the method comprising:

storing first information indicative of restrictive rights associated with the external sources;

storing second information indicative of restrictive rights associated with the media devices;

receiving a request at a requesting media device to obtain restricted media content;

determining from which external source to obtain the requested media content by comparing the first information to the second information, wherein the determined external source provides the requested media content with a restrictive right suitable for processing with at least one of the media devices on the network; and

obtaining the requested media content via the network from the determined external source.

16. The method of claim 15, wherein the media devices are selected from the group consisting of a portable electronic device, a portable music player, a cellular communication device, a home entertainment system, a personal computer, and a vehicular entertainment system.
