Abstract

A personal video service manager can store one or more personal video assets on a server. A personal video asset can include 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.

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 personalized playlist further identifies how the subscriber can navigate through the personal video asset and the other video asset.

28. The system for distributing a personal video asset of claim 1, wherein the personalized playlist comprises an index that indicates each location in the personal video asset where the at least one other video asset may be inserted during playback.

29. The system for distributing a personal video asset of claim 1, wherein the personal video service manager determines whether to insert the at least one other video asset based on the personal video asset requested and the subscriber'"'"'s subscription service.

30. The system for distributing a personal video asset of claim 1, wherein the personal video service manager determines whether to insert the at least one other video asset based on instructions received from an asset provider.

8. 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 metadata that describes a format of the personal video asset, the metadata comprising a default playlist for the personal video asset, wherein the default playlist informs a personal video service manager how at least one other video asset is inserted into or associated with the personal video asset; and

a personal video service manager, coupled to the video network, operative

to manage the personal video assets stored on the servers,

to create a playlist from the default playlist that instructs the server how to assemble the personal video asset during playback, 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.

9. The system of claim 8, 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.

10. The system of claim 8, 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.

11. 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, the personal video asset further comprising metadata that describes a format of the personal video asset, the metadata comprising a default playlist for the personal video asset, wherein the default playlist informs a personal video service manager how at least one other video asset is inserted into or associated with the personal video asset;

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

creating a playlist from the default playlist that instructs the server how to assemble the personal video asset during playback; and

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

12. The method for managing a personal video asset of claim 11, 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.
