1. A method for communicating the content of a live data stream to a receiver using a plurality of channels comprising one or more main channels having at least two sub-channels, the method comprising:

  • receiving a first segment of a live data stream, the first segment, S0, containing first segment data;

    applying a forward error correction algorithm the first segment data to produce a corresponding transmit block, T0;

    dividing the T0 block into two or more T0 sub-blocks, wherein each of the two or more T0 sub-blocks comprise substantially distinct FEC-encoded first segment data;

    transmitting a first of the two or more T0 sub-blocks to a receiver on a first main sub-channel;

    receiving a second segment of the live data stream, the second segment, S1, containing second segment data;

    applying a forward error correction algorithm to the second segment data to produce a transmit block T1;

    dividing the T1 block into two or more T1 sub-blocks, wherein each of the two or more T1 sub-blocks comprises substantially distinct FEC-encoded second segment data;

    transmitting substantially concurrently, the second of the two or more T0 sub-blocks on the first main sub-channel and a first of the two or more T1 sub-blocks on a second main sub-channel.
