1. A method comprises:

  • partitioning data into a first portion of fundamental component data and a second portion of enhancement component data, wherein the fundamental component data of the first portion includes content of the data of a higher priority than the enhancement component data of the second portion;

    dispersed storage error encoding the fundamental component data in accordance with dispersed storage error coding parameters to produce encoded data, segmenting the encoded data into a plurality of encoded data segments and slicing the plurality of encoded data segments into a plurality of sets of encoded data slices, wherein a set of the plurality of sets of encoded data slices corresponds to a data segment of the fundamental component data and wherein a threshold number of encoded data slices of the set of encoded data slices are required to reproduce the data segment;

    transmitting a set of the plurality of sets of encoded data slices to a receiving entity; and

    transmitting a corresponding portion of the enhancement component data substantially concurrently with the transmitting of the set of the plurality of sets of encoded data slices to the receiving entity.
