1. A transmission apparatus, comprising:
- a modulator to modulate a control signal to a frequency band within an audible frequency band;
a mixing unit to generate a voice mixed signal by mixing the modulate control signal with a voice signal; and
a transmitter to transmit the voice mixed signal to a reception apparatus,wherein the reception apparatus reproduces the voice mixed signal, and the control signal is extracted from the reproduced voice mixed signal and is used to control an electronic device.
