A method begins by a dispersed storage (DS) processing module concurrently receiving a first data stream and a second data stream for transmission to a receiving entity. The method continues with the DS processing module segmenting each of the first and second data streams to produce a first plurality of data segments and a second plurality of data segments, dividing one of the first plurality of data segments into a first plurality of data blocks, and dividing one of the second plurality of data segments into a second plurality of data blocks. The method continues with the DS processing module creating a data matrix from the first and second plurality of data blocks and generating a coded matrix from the data matrix and an encoding matrix. The method continues with the DS processing module outputting one or more pairs of coded values of the coded matrix to the receiving entity.
