1. An encoding method comprising the steps of:

  • encoding an input information object according to a first preset encoding scheme;

    selecting a preset set of bits from the encoded input information object, and outputting the selected preset set of bits as a sample;

    generating a control packet including information on the sample by encoding according to a second preset encoding scheme;

    assembling the sample with the control packet;

    modulating the assembled sample into a sound signal according to a preset modulation scheme; and

    transmitting the sound signal as an audible tone to an external receiving apparatus, using an acoustic communication channel,wherein the step of generating the control packet comprises;

    generating control data including information related to a size of the input information object and a sample number; and

    generating the control packet by encoding the control data according to the second preset encoding scheme.
