    摘要: A new data block to be stored in the dispersed storage system is received. When it is determined that a previous data segment contains sufficient space for the new data block, the previous data segment is retrieved from a plurality of dispersed storage units. A revised data segment is generated by aggregating the new data block with at least one existing data block of the previous data segment. A plurality of slices are generated for the revised data segment. The plurality of slices are stored in the plurality of dispersed storage units.

    摘要: A method begins by a dispersed storage (DS) processing module encoding a data segment of multi-media content using a dispersed storage error coding function to produce a set of encoded data slices and partitioning the set of encoded data slices into a first sub-set of encoded data slices and a second sub-set of encoded data slices, wherein the first sub-set of encoded data slices include less than a decode threshold number of encoded data slices. The method continues with the DS processing module distributing the first sub-set of encoded data slices to a plurality of potential accessing devices and when accessing information from a device of the plurality of potential accessing devices is received, sending at least one of the encoded data slices of the second sub-set of encoded data slices to the device such that the device has the decode threshold number of encoded data slices.
