Abstract:
A centralized DVR includes a dispersed storage error encoding module, storage nodes, and a distribution module. The dispersed storage error encoding module encodes a broadcast of data in accordance with an error coding dispersal storage function to produce a plurality of sets of encoded data slices, which is stored in the storage nodes. For a first playback request, the distribution module determines a first unique combination and retrieves, as a first unique copy of the broadcast data from the storage nodes, encoded data slices of the plurality of sets of encoded data slices in accordance with the first unique combination. For a second playback request, the distribution module determines a second unique combination and retrieves, as a second unique copy of the broadcast data from the storage nodes, encoded data slices of the plurality of sets of encoded data slices in accordance with the second unique combination.
