1. A spectrum generation apparatus configured to distribute a plurality of digital content from a plurality of content sources to a plurality of users of a service group, said spectrum generation apparatus comprising:

  • one or more network interfaces adapted to receive said plurality of digital content fromsaid plurality of content sources via one or more Time Domain Multiplexed (TDM) data streams, said plurality of digital content being characterized by a proportion of one or more narrowcast programs to other content;

    a downstream interface in communication with said plurality of users of said service group via one or more frequency resources;

    one or more demultiplexers configured to demultiplex said one or more TDM data streams; and

    programmable inverse Fast Fourier Transform (IFFT) apparatus configured to multiplex said demultiplexed one or more TDM data streams into a Frequency Domain Multiplexed (FDM) data stream for transmission to said plurality of users of said service group via said one or morefrequency resources, said programmable IFFT apparatus further configured to assign individual ones of said plurality of digital content to two or more of said frequency resources as a function of time, and thereby provide time and frequency diversity; and

    wherein said programmable apparatus is further configured to dynamically adjust said proportion of one or more narrowcast programs to other content responsive to a change in anumber of said plurality of users of said service group.
