Abstract

To be accessed on different media players, requested content must be delivered in a format that is supported by the requesting device. A dynamic content packager for encrypting and packaging requested content for different requesting devices at the time of consumption is disclosed.

Claims

1. A method, comprising:

receiving, by a processor, a content request from a device;

determining, by the processor, a device profile for the device, the device profile indicating device capabilities for the device;

based on the received content request and determined device profile, determining, by the processor, at least one content packager for packaging the requested content;

determining, by the processor, a content delivery mute;

retrieving packaging metadata and encryption keys for the requested content;

packaging the requested content; and

delivering the requested content along the determined content delivery route to the device.

2. The method of claim 1, further comprising encrypting the requested content.

3. The method of claim 1, wherein determining the content delivery route further comprises determining resource availability of the content packager.

4. The method of claim 1, wherein determining the content delivery route farther comprises determining content availability.

5. The method of claim 1, wherein determining the content packager further comprises:

determining based on the received content request and determined device profile, content packager capabilities for packaging the requested content.

6. The method of claim 1, further comprising determining a geographical location for the device.

8. A method, comprising:

receiving, by a processor, a content request from a device;

determining, by the processor, a device profile for the device, the device profile indicating device capabilities for the device;

based on the received content request and determined device profile, determining, by the processor, at least one content packager for packaging the requested content;

determining, by the processor, a content delivery route;

if the requested content is stored in cache along the determined content delivery route, delivering the requested content from the cache to the device; and

if the requested content is not stored along the content delivery route,

retrieving packaging metadata and encryption keys for the requested content;

packaging the requested content; and

delivering the requested content along the determined content delivery route to the device,

9. The method of claim 8, further comprising encrypting the requested content for delivery to the device,

10. The method of claim 8, wherein determining the content delivery route further comprises determining resource availability of the content packager.

11. The method of claim 8, wherein determining the content delivery mute further comprises determining content availability

12. The method of claim 8, wherein determining the content packager further comprises:

determining based on the received content request and determined device profile, content packager capabilities for packaging the requested content.

13. The method of claim 8, further comprising determining a geographical location for the device.

14. The method of claim 8, wherein determining the content delivery route farther comprises determining availability of content streamers along the content delivery route.

15. The method of claim 14, further comprising selecting a content streamer from the determined available content streamers for delivery of the requested content.

16. The method of claim 8, wherein determining the content delivery route further comprises determining on/off network status.

17. The method of claim 8, wherein determining the content delivery route further comprises determining proximity of content streamer to device.

18. An apparatus comprising:

at least one processor; and

at least one memory having stored therein machine executable instructions, the at least one memory and stored instructions configured to, with the at least one processor, cause the apparatus to;

receive a content request from a device;

determine a device profile for the device, the device profile indicating device capabilities for the device;

based on the received content request and determined device profile, determine at least one content packager for packaging the requested content;

determine a content delivery route;

retrieve packaging metadata and encryption keys for the requested content;

package the requested content; and

deliver the requested content along the determined content delivery route to the device.

19. The apparatus of claim 18, wherein the content packager comprises an ingress content packager.

20. The apparatus of claim 18, wherein the apparatus comprises a gateway device.
