1. A system for sharing a single transmitter spectrum across multiple analog spectrums, the system comprising:
at least one modulator for generating and transmitting analog content to a plurality of transmitters, wherein a frequency of a first analog content transmitted to a digital transmitter is generated by the at least one modulator to be non-overlapping with frequencies of analog content transmitted to a plurality of analog transmitters; the digital transmitter receiving the first analog content, that is common among each of a plurality of users, from the at least one modulator, said digital transmitter sampling and digitizing said entire spectrum of the first content input to the digital transmitter; the plurality of analog transmitters, each analog transmitter for receiving analog content common among only a subset of said plurality of users from the at least one modulator; each analog transmitter outputting at least one analog output representative of said respectively received analog content; a summation network directing to a first node a first signal that includes:
a first digital representation of said entire spectrum of the first analog content input to the digital transmitter and digitally output from the digital transmitter, andthe analog representation of analog content output from a first one of the plurality of analog transmitters, the summation network directing to a second node a second signal that includes:
a second digital representation of said entire spectrum of the first analog content input to the first transmitter and digitally output from the first transmitter, andthe analog representation of analog content output from a second one of the plurality of analog transmitters. |
