Abstract

A personal video service manager can store one or more personal video assets on a server. A personal video asset can comprise a recording of a broadcast stream of a broadcast asset or an asset that has been pre-authored in a personal video asset format. Upon receiving a request from a subscriber to receive the personal video asset, the personal video service manager can facilitate a connection between the server and the subscriber for distributing the personal video asset from the server to the subscriber.

1. A system for distributing a personal video asset to at least one subscriber via a video network, comprising:

a server, operative to store the personal video asset, wherein the personal video asset comprises a recording of a broadcast stream of a broadcast asset; and

a personal video service manager, coupled to the video network, operative to store the personal video asset on the server and to facilitate a connection for distributing the personal video asset from the server to the subscriber upon receiving a request from the subscriber to receive the personal video asset.

2. The system for distributing a personal video asset of claim 1, further comprising:

a transmitter, operative to send the personal video asset to the subscriber via the video network upon receiving the request; and

a receiver, operative to receive the personal video asset from the transmitter via the video network and to distribute the personal video asset to the subscriber.

3. The system for distributing a personal video asset of claim 1, further comprising a broadcast segment processor, operative to record the broadcast stream of the broadcast asset and to format the recording as the personal video asset.

4. The system for distributing a personal video asset of claim 3, wherein the broadcast segment processor is further operative to record the broadcast stream of the broadcast asset in response to receiving a request from the personal video service manager to record the broadcast stream.

5. The system for distributing a personal video asset of claim 1, wherein the server comprises a distributed personal video server, operative to service at least one group of subscribers and to receive the personal video asset via the video network from the personal video service manager.

6. The system for distributing a personal video asset of claim 1, wherein the personal video service manager is further operative to receive an asset from an asset provider, wherein the asset is pre-authored by the asset provider in a personal video asset format.

7. The system for distributing a personal video asset of claim 1, wherein the personal video service manager is further operative to create a personalized playlist identifying at least one location in the personal video asset wherein at least one asset can be inserted.

8. The system for distributing a personal video asset of claim 7, wherein the personalized playlist further identifies how the subscriber can view the personal video asset.

9. A system for distributing a selected one of a plurality of personal video assets to a subscriber via a video network, comprising:

a plurality of servers, operative to store the personal video assets, wherein each personal video asset comprises a recording of a broadcast stream of a broadcast asset; and

a personal video service manager, coupled to the video network, operative to manage the personal video assets stored on the servers, and upon receiving a request from the subscriber to receive the selected personal video asset, operative to identify a selected one of the plurality of servers that stores the selected personal video asset and to facilitate a connection between the subscriber and the selected server for distributing the selected personal video asset to the subscriber.

10. The system of claim 9, further comprising:

a transmitter, operative to send the selected personal video asset via the video network to the subscriber; and

a receiver, operative to receive the selected personal video asset from the transmitter via the video network and to distribute the selected personal video asset to the subscriber.

11. The system of claim 9, further comprising a broadcast segment processor, operative to record the broadcast stream of the broadcast asset and to format the recording as the personal video asset in response to receiving a request from the personal video service manager to record the broadcast stream.

12. A method for managing a personal video asset, comprising the steps of:

recording an identified broadcast asset from a broadcast stream and formatting the recorded broadcast asset as the personal video asset;

storing the formatted personal video asset on a selected one of a plurality of servers; and

facilitating a connection between a subscriber and the selected server upon receiving a request from the subscriber to view the personal video asset.

13. The method for managing a personal video asset of claim 12, wherein the facilitating step comprises the steps of:

identifying the selected server that stores the personal video asset; and

distributing the personal video asset from the selected server to the subscriber via a video network.

14. The method for managing a personal video asset of claim 13, wherein the distributing step comprises the steps of:

retrieving the personal video asset from the selected server; and

sending the personal video asset from a transmitter via the video network.

15. The method for managing a personal video asset of claim 13, further comprising the steps of:

determining whether to distribute the personal video asset to at least one distributed personal video server; and

sending the personal video asset to the at least one distributed personal video server via the video network, if the personal video asset is to be distributed to the distributed personal video server.

16. The method for managing a personal video asset of claim 12, further comprising the step of creating a playlist identifying at least one location in the personal video asset wherein at least one asset can be inserted.

17. A method for managing a plurality of personal video assets, comprising the steps of:

formatting a recording of a broadcast stream of a broadcast asset as a selected one of the plurality of personal video assets;

receiving a request to view the selected personal video asset;

identifying a server that stores the selected personal video asset; and

facilitating a connection between the server and an entity issuing the request.

18. The method of claim 17, comprising the step of storing each personal video asset on at least one of a plurality of servers.

19. The method of claim 17, comprising the steps of:

distributing the personal video asset to at least one of a plurality of distributed personal video servers; and

21. The method of claim 19, wherein the server comprises the distributed personal video server.

22. The method of claim 17, comprising the step of recording the broadcast stream of the broadcast asset in response to receiving a request to record the broadcast stream.

23. The method of claim 17, wherein at least one of the plurality of personal video assets comprises a pre-authored personal video asset received from an asset provider.

24. The method of claim 17, further comprising the step of creating a playlist identifying at least one location in the personal video asset wherein at least one asset can be inserted.

25. A system for distributing a personal video asset to at least one subscriber via a video network, comprising:

a server, operative to store the personal video asset, wherein the personal video asset comprises a recording of a broadcast stream of a broadcast asset;

a broadcast segment processor, operative to record the broadcast stream of the broadcast asset and to format the recording as the personal video asset; and

a personal video service manager, coupled to the video network, operative to store the personal video asset on the server and to facilitate a connection for distributing the personal video asset from the server to the subscriber upon receiving a request from the subscriber to receive the personal video asset.

26. The system for distributing a personal video asset of claim 25, wherein the broadcast segment processor is further operative to record the broadcast stream of the broadcast asset in response to receiving a request from the personal video service manager to record the broadcast stream.
