Proximity communication system and proximity communication apparatus

A proximity communication apparatus comprising:

• a proximity communication section which is configured to perform proximity communication;
• a high-speed communication section which is configured to perform high-speed communication, which is faster than the proximity communication, with a second device which is configured to reproduce audio data;
• a storage section in which authentication information for authenticating a mobile terminal device which is configured to reproduce the audio data and includes a communication section that communicates with the proximity communication section is stored;
• and
• a control section which is configured to authenticate the mobile terminal device by using the authentication information when the proximity communication section starts communication with the communication section of the mobile terminal device, and which is configured to relay, by using the proximity communication section and the high-speed communication section, communication between the mobile terminal device and the second device in response to the authentication being successful, wherein
• when the communication between the mobile terminal device and the second device is relayed by the control section, a control section of the mobile terminal device transmits, to the second device via the control section, at least one of operation information indicating an operation state at a time when the communication between the mobile terminal device and the second device is relayed by the control section and setting information indicating a function setting state at the time,
• when receiving the at least one of the operation information and the setting information, a control section of the second device starts operation based on the received information, and
• the control section of the mobile terminal device stops operation based on the information transmitted to the second device.

A method of controlling a proximity communication apparatus including:

• a proximity communication section which is configured to perform proximity communication;
• a high-speed communication section which is configured to perform high-speed communication, which is faster than the proximity communication, with a second device which is configured to reproduce audio data;
• and a storage section in which authentication information for authenticating a mobile terminal device which is configured to reproduce the audio data and includes a communication section that communicates with the proximity communication section is stored, the method comprising:
• authenticating the mobile terminal device by using the authentication information when the proximity communication section starts communication with the communication section of the mobile terminal device;
• and
• relaying, by using the proximity communication section and the high-speed communication section, communication between the mobile terminal device and the second device in response to the authentication being successful, wherein
• when the communication between the mobile terminal device and the second device is relayed by the proximity communication section and the high-speed communication section, a control section of the mobile terminal device transmits, to the second device via the proximity communication section and the high-speed communication section, at least one of operation information indicating an operation state at a time when the communication between the mobile terminal device and the second device is relayed by the proximity communication section and the high-speed communication section and setting information indicating a function setting state at the time,
• when receiving the at least one of the operation information and the setting information, a control section of the second device starts operation based on the received information, and
• the control section of the mobile terminal device stops operation based on the information transmitted to the second device.
