Patent ID: 8358980

Claim:
A wireless audio transfer system comprising: an audio transmitting apparatus including a microphone and a modulating/transmitting unit for transmitting radio waves modulated using an audio signal from the microphone; an audio receiving apparatus including a receiving/demodulating unit for receiving the radio waves transmitted from the audio transmitting apparatus and demodulating the audio signal and an audio output terminal for outputting the audio signal demodulated by the receiving/demodulating unit; and an image pickup apparatus including an audio input terminal for inputting the audio signal outputted from the audio receiving apparatus, wherein the audio transmitting apparatus further includes a detecting unit for detecting distortion of an audio signal and a data transmitting unit for transmitting, as radio waves, distortion status data showing a detection result of the detecting unit, the audio receiving apparatus further includes a first communication terminal and a data processing unit for obtaining the distortion status data from the received radio waves and outputting the distortion status data from the first communication terminal, and the image pickup apparatus includes a second communication terminal for inputting the distortion status data outputted from the first communication terminal of the audio receiving apparatus, a display unit, and a first control unit for displaying, based on the distortion status data inputted into the second communication terminal, whether audio distortion is present at the audio transmitting apparatus on the display unit, wherein the distortion status data is included in a packet signal that is appended to the audio signal or the distortion status data is transmitted as a subcarrier of a different frequency band to a main carrier, the main carrier being radio waves used to transmit the audio signal.
