Abstract

Claims (80)

1. A method for dispersed storage of streaming multi-media data, the method comprises:

determining dispersed storage preferences for the streaming multi-media data;

transcoding the streaming multi-media data into transcoded data when the dispersed storage preferences include transcoding;

encoding the transcoded data in accordance with an error coding dispersed storage function of the dispersed storage preferences to produce pluralities of error coded data slices; and

outputting the pluralities of error coded data slices to a plurality of data storage units for storage therein.

2. The method of claim 1 further comprises:

receiving the streaming multi-media data.

3. The method of claim 1 further comprises:

determining whether to partition the streaming multi-media data into a plurality of data streams based on the dispersed storage preferences; and

when the streaming multi-media data is to be partitioned into the plurality of data streams:

transcoding each of the plurality of data streams to produce a plurality of transcoded data streams in accordance with the dispersed storage preferences; and

encoding each of the plurality of transcoded data streams into a plurality of sets of error coded data slices as the pluralities of error coded data slices.

4. The method of claim 1 further comprises:

partitioning the transcoded data into a plurality of transcoded data streams in accordance with the dispersed storage preferences; and

encoding each of the plurality of transcoded data streams in accordance with the error coding dispersed storage function of the dispersed storage preferences to produce a plurality of sets of error coded data slices as the pluralities of error coded data slices.

5. The method of claim 1 further comprises at least one of:

pre-slice data manipulation of at least a portion of the transcoded data; and

post-slice data manipulation of an error coded data slice of the pluralities of error coded data slices.

6. A method for retrieving streaming multi-media data from a dispersed storage system, the method comprises:

determining dispersed storage retrieval preferences for the streaming multi-media data;

accessing a plurality of data storage units to retrieve pluralities of error coded data slices therefrom;

per plurality of the pluralities of error coded data slices, decoding at least a threshold number of the error coded data slices in accordance with an error coding dispersed storage function of the dispersed storage retrieval preferences to produce a decoded data segment;

aggregating the decoded data segments to produce a retrieved multi-media data; and

transcoding the retrieved multi-media data into the streaming multi-media data when the dispersed storage retrieval preferences include transcoding.

7. The method of claim 6 further comprises:

outputting the streaming multi-media data.

8. The method of claim 6 further comprises:

retrieving a plurality of sets of error coded data slices as the pluralities of error coded data slices;

decoding the plurality of sets of error coded data slices into a corresponding plurality of data streams; and

combining the plurality data streams into the retrieved multi-media data.

9. The method of claim 6 further comprises:

retrieving a plurality of sets of error coded data slices as the pluralities of error coded data slices;

decoding the plurality of sets of error coded data slices into a corresponding plurality of data streams;

transcoding the corresponding plurality of data streams into a plurality of transcoded data streams; and

combining the plurality of transcoded data streams into the streaming multi-media data.

10. The method of claim 6 further comprises at least one of:

pre-slice data de-manipulation of the decoded data segment; and

post-slice data de-manipulation of an error coded data slice of the pluralities of error coded data slices.

11. A computer comprises:

an interface; and

a processing module operable to:

determine dispersed storage preferences for streaming multi-media data;

transcode the streaming multi-media data into transcoded data when the dispersed storage preferences include transcoding;

encode the transcoded data in accordance with an error coding dispersed storage function of the dispersed storage preferences to produce pluralities of error coded data slices; and

output, via the interface, the pluralities of error coded data slices to a plurality of data storage units for storage therein.

12. The computer of claim 11 , wherein the processing module further functions to:

receive, via the interface, the streaming multi-media data.

13. The computer of claim 11 , wherein the processing module further functions to:

determine whether to partition the streaming multi-media data into a plurality of data streams based on the dispersed storage preferences; and

when the streaming multi-media data is to be partitioned into the plurality of data streams:

transcode each of the plurality of data streams to produce a plurality of transcoded data streams in accordance with the dispersed storage preferences; and

encode each of the plurality of transcoded data streams into a plurality of sets of error coded data slices as the pluralities of error coded data slices.
