Abstract

A method, using a dispersed storage processing module, includes receiving media content determining social media metadata regarding the media content, encoding the media content in accordance with an error coding dispersal storage function to produce a plurality of sets of encoded data slices, identifying a plurality of memories to store the plurality of sets of encoded data slices, and sending the plurality of sets of encoded data slices to the plurality of memories when the social media metadata indicates that the media content is to be available for a local social network.

Claims

1. A method for execution by a dispersed storage processing module, the method comprises:

receiving media content;

determining social media metadata regarding the media content; and

when the social media metadata indicates that the media content corresponds to a local social network;

encoding the media content in accordance with an error coding dispersal storage function associated with the local social network to produce a plurality of sets of encoded data slices;

identifying a plurality of memories to store the plurality of sets of encoded data slices; and

sending the plurality of sets of encoded data slices to the plurality of memories.

2. The method of claim 1 further comprises:

receiving the media content in response to a selection, wherein the selection includes at least one of;

selecting the media content from a media selection list;

receiving a command from a media content source; and

receiving a request from another member of the local social network.

3. The method of claim 1, wherein the determining the social media metadata further comprises one or more of:

determining other members of the local social network;

determining that the other members have not previously encoded and facilitated storage of the media content;

determining that at least one of the other members has indicated a request to encode and facilitate storage of the media content; and

receiving the social media metadata from a local social network manager.

4. The method of claim 1, wherein the plurality of memories comprises one or more of:

a memory within a member of the local storage network; and

a memory of a dispersed storage network.

5. The method of claim 1, wherein the receiving the media content comprises at least one of:

receiving the media content from a commercial media content provider;

receiving the media content from a private media content provider; and

receiving the media content from a member of the local social network.

6. A method for execution by a dispersed storage processing module, the method comprises:

selecting media content to retrieve;

obtaining social media metadata regarding the media content;

retrieving a plurality of sets of encoded data slices from a plurality of memories based on the social media metadata;

re-creating the media content from the plurality of sets of encoded data slices in accordance with an error coding dispersal storage function associated with a local social network to produce reconstructed media content;

determining, based on the social media metadata, members of the local social network to receive the reconstructed media content to produce identified members; and

sending the reconstructed media content to the identified members.

7. The method of claim 6, wherein the plurality of memories comprises one or more of:

a memory within a member of the local storage network; and

a memory of a dispersed storage network.

8. The method of claim 6, wherein the social media metadata comprises at least one of:

a media selection list;

a social network member list;

a stored media content list; and

a dispersed-storage-address-to-memory-location table.

9. The method of claim 6, wherein the sending further comprises at least one of:

encrypting the media content; and

compressing the media content.

10. The method of claim 6, wherein the sending further comprises:

determining a display protocol for each of the identified members; and

converting format of the reconstructed media content in accordance with the display protocol of one of the identified members.

11. A dispersed storage processing module comprises:

an interface;

a memory; and

a processing module operable to;

receive, via the interface, media content;

determine social media metadata regarding the media content; and

when the social media metadata indicates that the media content corresponds to a local social network;

encode the media content in accordance with an error coding dispersal storage function associated with the local social network to produce a plurality of sets of encoded data slices;

identify a plurality of memories to store the plurality of sets of encoded data slices; and

send, via the interface, the plurality of sets of encoded data slices to the plurality of memories.
