Abstract

A content delivery network includes an overlay network having a plurality of cache servers. Each cache server configured to receive a request from a personal content server to register with the content delivery network, receive a request from a mobile capture device to establish communication with the personal content server, and establish a communication path through the overlay network between the mobile capture device and the personal content server. Each cache server is further configured to transfer content from the mobile capture device along the communication path to the personal content server.

establishing a first communication path through an overlay network between the mobile video capture device and the personal content server;

providing the mobile video capture device with a list of capabilities of an available display device, wherein the list of capabilities includes a resolution needed by the available display device;

exchanging encryption keys with the mobile capture device;

verifying, by utilizing instructions from a memory that are executed by a processor, that incoming content is from an authorized mobile capture device based on the encryption keys exchanged with the mobile capture device;

transferring the content from the mobile video capture device along the first communication path to the personal content server;

establishing a second communication path through the overlay network between the mobile video capture device and the personal content server when the first communication path is overloaded; and

transferring the content from the mobile video capture device along the second communication path to the personal content server based on a prioritization associated with a transfer of the content that is set by the mobile video capture device when bandwidth is limited, wherein the content is captured by the mobile video capture device when the bandwidth is insufficient for a real-time stream, wherein the prioritization associated with the transfer of the content is set based on the list of capabilities of the available display device, and wherein the content is formatted by the mobile video capture device based on the list of capabilities of the available display device;

whereby the personal content server provides the content to a digital picture frame and one of a set-top box, a television, a stereo system, personal computer, and laptop.

2. The method of claim 1, wherein the mobile capture device is selected from a group consisting of a video camera, digital camera, and digital audio recorder.

3. The method of claim 1, wherein the content is transferred along the second communication path without being stored by the content delivery network.

4. The method of claim 1, further comprising maintaining a list of personal content servers.

5. The method of claim 1, further comprising maintaining a list of mobile capture devices authorized to provide the content to the personal content server.

6. A content delivery network, comprising:

a memory that stores instructions;

a processor that executes the instructions to perform operations, comprising;

receiving a request from a personal content server to register with the content delivery network, wherein the personal content server is located at a customer premises, and wherein the personal content server is registered with the content delivery network based on a first electronic serial number;

receiving a request from a mobile video capture device to establish communication with the personal content server, wherein the mobile capture device is registered with the content delivery network based on a second electronic serial number;

establishing a first communication path through an overlay network between the mobile video capture device and the personal content server;

providing the mobile video capture device with a list of capabilities of an available display device, wherein the list of capabilities includes a resolution needed by the available display device;

exchanging encryption keys with the mobile capture device;

verifying that incoming content is from an authorized mobile capture device based on the encryption keys exchanged with the mobile capture device;

transferring the content from the mobile video capture device along the first communication path to the personal content server;

establishing a second communication path through the overlay network between the mobile video capture device and the personal content server when the first communication path is overloaded; and

transferring the content from the mobile video capture device along the second communication path to the personal content server based on a prioritization associated with a transfer of the content that is set by the mobile video capture device when bandwidth is limited, wherein the content is captured by the mobile video capture device when the bandwidth is insufficient for a real-time stream, wherein the prioritization associated with the transfer of the content is set based on the list of capabilities of the available display device, and wherein the content is formatted by the mobile video capture device based on the list of capabilities of the available display device;

whereby the personal content server provides the content to a digital picture frame and one of a set-top box, a television, a stereo system, personal computer, and laptop.

7. The content delivery network of claim 6, wherein the content is transferred along the second communication path without being stored by the content delivery network.

19. The content delivery network of claim 6, wherein the content is broadcast, via the overlay network, from the mobile video capture device to multiple personal content servers located at different locations.

20. The content delivery network of claim 6, wherein the content is transferred along the second communication path to the personal content server via one of a reduced bit rate of audio or video content, a reduced resolution of image content, and an extended amount of time to transfer the content based on an available amount of bandwidth.

8. A non-transitory computer-readable medium comprising instructions, which, when loaded and executed by a processor, cause the processor to perform operations, the operations comprising:

receiving a request from a personal content server to register with a content delivery network, wherein the personal content server is located at a customer premises, and wherein the personal content server is registered with the content delivery network based on a first electronic serial number;

receiving a request from a mobile video capture device to establish communication with the personal content server, wherein the mobile capture device is registered with the content delivery network based on a second electronic serial number;

establishing a first communication path through an overlay network between the mobile video capture device and the personal content server;

providing the mobile video capture device with a list of capabilities of an available display device, wherein the list of capabilities includes a resolution needed by the available display device;

exchanging encryption keys with the mobile capture device;

verifying that incoming content is from an authorized mobile capture device based on the encryption keys exchanged with the mobile capture device;

transferring the content from the mobile video capture device along the first communication path to the personal content server;

establishing a second communication path through the overlay network between the mobile video capture device and the personal content server when the first communication path is overloaded; and

transferring the content from the mobile video capture device along the second communication path to the personal content server based on a prioritization associated with a transfer of the content that is set by the mobile video capture device when bandwidth is limited, wherein the content is captured by the mobile video capture device when the bandwidth is insufficient for a real-time stream, wherein the prioritization associated with the transfer of the content is set based on the list of capabilities of the available display device, and wherein the content is formatted by the mobile video capture device based on the list of capabilities of the available display device;
