1. A satellite modem comprising:

  • an input configured to receive signals from a satellite, the signals forming a forward channel and including first and second sub-channels;

    a splitter communicatively coupled to the input and configured to separate headers of the signals from payloads of the signals and to output the headers as a first output and to output the payloads as a second output;

    a demodulator communicatively coupled to the splitter to receive the first output and configured to demodulate the headers;

    a controller communicatively coupled to the demodulator and configured to analyze demodulated headers from the demodulator and to produce a first indication that an analyzed header corresponds to a sub-channel allocated to the satellite modem; and

    a buffer communicatively coupled to the splitter and the controller and configured to store a payload corresponding to the analyzed header in response to the first indication.
