Abstract

An apparatus, system and method are disclosed for resolving bandwidth constriction using multiple bandwidths and/or multiple content delivery paths. The apparatus, system and method may include recording requested video content and/or delivering the recorded video content to resolve bandwidth constriction using alternate bandwidths or delivery paths.

First claim

The invention claimed is:

1. A method comprising:
receiving a request for content associated with a user device; and
based on a determination that a unicast delivery path via a first computing device is unavailable for delivering the content to the user device, causing sending at least a portion of the content to the user device via a second computing device and via an alternative delivery path different from the unicast delivery path.

2. The method of claim 1 , wherein the alternative delivery path comprises a multicast delivery path.

3. The method of claim 1 , wherein at least one of the unicast delivery path or the alternative delivery path comprises one or more of:
a satellite;
a local area network;
a wireless delivery path;
a packet switched network; or
a mobile network.

4. The method of claim 1 , further comprising determining that the unicast delivery path is unavailable by determining that there is insufficient bandwidth for delivery of the content via the unicast delivery path.

5. The method of claim 1 , further comprising:
based on the determination that the unicast delivery path is unavailable, performing at least one of:
causing sending a message, to the user device, indicating that the unicast delivery path is unavailable; or
causing sending a message, to the user device, allowing a user of the user device to select the alternative delivery path for delivering the content to the user device.

6. The method of claim 1 , further comprising:
based on the determination that the unicast delivery path is unavailable, selecting, based on a database identifying a plurality of delivery paths, the alternative delivery path.

7. The method of claim 1 , further comprising:
receiving, from the user device, a message requesting delivery of the content via the alternative delivery path,
wherein the causing sending is further based on the receiving the message.

8. The method of claim 1 , wherein the second computing device comprises one or more of:
a network digital video recorder (nDVR);
a remote storage digital video recorder (RS-DVR);
a vault server; a gateway server; or
an edge server.

9. The method of claim 1 , further comprising causing the second computing device to store the content.

10. The method of claim 1 , further comprising:
causing sending a second portion of the content via the unicast delivery path and via the first computing device prior to causing sending the at least the portion of the content to the user device via the second computing device and via the alternative delivery path.

11. An apparatus comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the apparatus to:
receive a request for content associated with a user device; and
based on a determination that a unicast delivery path via a first computing device is unavailable for delivering the content to the user device, cause sending at least a portion of the content to the user device via a second computing device and via an alternative delivery path different from the unicast delivery path.

12. The apparatus of claim 11 , wherein the alternative delivery path comprises a multicast delivery path.

13. The apparatus of claim 11 , wherein at least one of the unicast delivery path or the alternative delivery path comprises one or more of:
a satellite;
a local area network;
a wireless delivery path;
a packet switched network; or
a mobile network.

14. The apparatus of claim 11 , wherein the instructions, when executed by the one or more processors, further cause the apparatus to determine that the unicast delivery path is unavailable by determining that there is insufficient bandwidth for delivery of the content via the unicast delivery path.

15. The apparatus of claim 11 , wherein the instructions, when executed by the one or more processors, further cause the apparatus to, based on the determination that the unicast delivery path is unavailable, perform at least one of:
cause sending a message, to the user device, indicating that the unicast delivery path is unavailable; or
cause sending a message, to the user device, allowing a user of the user device to select the alternative delivery path for delivering the content to the user device.

16. The apparatus of claim 11 , wherein the instructions, when executed by the one or more processors, further cause the apparatus to:
cause sending a second portion of the content via the unicast delivery path and via the first computing device prior to causing sending the at least the portion of the content to the user device via the second computing device and via the alternative delivery path.

17. A non-transitory computer-readable medium storing instructions that, when executed, cause:
receiving a request for content associated with a user device; and
based on a determination that a unicast delivery path via a first computing device is unavailable for delivering the content to the user device, causing sending at least a portion of the content to the user device via a second computing device and via an alternative delivery path different from the unicast delivery path.

18. The non-transitory computer-readable medium of claim 17 , wherein the alternative delivery path comprises a multicast delivery path.

19. The non-transitory computer-readable medium of claim 17 , wherein at least one of the unicast delivery path or the alternative delivery path comprises one or more of:
a satellite;
a local area network;
a wireless delivery path;
a packet switched network; or
a mobile network.

20. The non-transitory computer-readable medium of claim 17 , wherein the instructions, when executed, further cause determining that the unicast delivery path is unavailable by determining that there is insufficient bandwidth for delivery of the content via the unicast delivery path.

21. The non-transitory computer-readable medium of claim 17 , wherein the instructions, when executed, further cause, based on the determination that the unicast delivery path is unavailable, performing at least one of:
causing sending a message, to the user device, indicating that the unicast delivery path is unavailable; or
causing sending a message, to the user device, allowing a user of the user device to select the alternative delivery path for delivering the content to the user device.

22. The non-transitory computer-readable medium of claim 17 , wherein the instructions, when executed, further cause:
causing sending a second portion of the content via the unicast delivery path and via the first computing device prior to causing sending the at least the portion of the content to the user device via the second computing device and via the alternative delivery path.

23. A system comprising:
a first computing device; and
a user device,
wherein the first computing device comprises:
one or more first processors; and
first memory storing first instructions that, when executed by the one or more first processors, cause the first computing device to:
receive a request for content associated with the user device; and
based on a determination that a unicast delivery path via a second computing device is unavailable for delivering the content to the user device, cause sending at least a portion of the content to the user device via a third computing device and via an alternative delivery path different from the unicast delivery path,
