1. A method for hierarchical communication of a set of source data, the method comprising:

  • receiving source data representing content to be communicated to a data terminal;

    pre-coding at least some of the source data using a first pre-coding scheme to generate a first set of representation data, decodable independently to provide a set of first-level playback data representing the source data;

    pre-coding at least some of the source data using a second pre-coding scheme to generate a second set of representation data, decodable in combination with the first set of representation data to provide a set of second-level playback data representing the source data;

    associating the first set of representation data with a first coding and modulation scheme;

    associating the second set of representation data with a second coding and modulation scheme, wherein the second coding and modulation scheme is of a higher order than the first coding and modulation scheme;

    generating a first transmission by applying the first coding and modulation scheme to the first set of representation data;

    generating a second transmission by applying the second coding and modulation scheme to the second set of representation data;

    transmitting the first transmission to the data terminal on a first communication link; and

    transmitting the second transmission to the data terminal on a second communication link, wherein the second communication link differs from the first communication link.
