  Next, embodiments of the present invention will be described with reference to the drawings. The following embodiments exemplify apparatuses and methods for embodying the technical idea of the present invention, and programs used in these apparatuses. The technical idea of the present invention is described below. The present invention is not limited to the devices and methods exemplified in the embodiments and the programs used for these devices. The technical idea of the present invention can be variously modified within the technical scope described in the claims.

  As shown in FIG. 1, the connection setting system according to the embodiment of the present invention forms a wireless network (internal network) 5 by connecting to other terminals, and the wireless network 5 and the Internet (external network) 6 A relay device 2 that relays communications between the two, a PC terminal 3 that is connected to the relay device 2, a transmitter 4 that multiplexes and transmits data to radio waves in the broadcast wave wavelength region, and a broadcast wave wavelength region And a communication device 1 that receives radio waves.

  The communication device 1 includes, for example, a so-called wireless LAN radio that stream-distributes multimedia signals such as audio and video acquired from broadcast waves to other terminals in real time via a network. The relay device 2 is composed of a wireless LAN router.

  The PC terminal 3 is connected to the relay device 2 wirelessly. The PC terminal 3 is one of the other terminals, and receives the multimedia signal stream-distributed from the communication device 1 via the relay device 2. The PC terminal 3 includes a storage unit 32 that stores connection setting information necessary for connection with the communication unit 31, and an output unit 33 that reads the connection setting information from the storage unit 32 and outputs it. The connection setting information is information necessary for setting a connection with the relay device 2 that is a wireless LAN router. The connection setting information is, for example, an SSID (Service Set Identifier) that is an identifier for identifying the relay device 2 of each standard such as IEEE802.11b, g, n, an encryption method, an encryption key, and the like.

  The SSID is an identifier associated with the relay apparatus 2, and is represented by, for example, a maximum of 32 alphanumeric characters. The encryption method is, for example, NONE indicating no encryption, WEP (Wired Equivalent Privacy) which is a secret key encryption method based on the RC4 (Rivest's Cipher 4) algorithm, and an encryption method for generating a temporary encryption key. It is selected from TKIP (Temporal Key Integrity Protocol), AES (Advanced Encryption Standard) which is an encryption method for secret key block cipher, and is represented by a character string such as NONE, WEP, TKIP, AES or the like. The encryption key is, for example, alphanumeric characters consisting of a maximum of 63 characters.

  The transmitter 4 includes an input unit 41 that inputs connection setting information output from the PC terminal 3, a multiplexing unit 42 that multiplexes the connection setting information input by the input unit 41 into radio waves in the wavelength region of broadcast waves, And a transmitter 43 that transmits the multiplexed radio wave. The transmitter 4 includes, for example, an FM transmitter having an RDS (Radio Data System) function for multiplexing data on FM radio broadcast waves. For example, the transmitter 4 multiplexes the connection setting information in the RT (Radio Text) portion of the RDS in the data structure of the signal to be multiplexed. In this case, the output unit 33 of the PC terminal 3 may output the connection setting information stored in the storage unit 32 to the transmitter 4 as RDS data.

  The RT portion of the RDS is a portion that transmits the name of a song being broadcast in actual broadcasting. Specifically, since the number of characters that can be transmitted at one time by the RT unit is limited to 64 characters, the transmitter 4 divides and transmits, for example, as follows. First transmission: 'SSID-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX' (XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX is the identifier of the relay device 2) Second transmission: 'ENC-YYYYY' (YYYYY is NONE, WEP, TKIP, or AES), Third transmission: 'KEY-ST' (Key transmission start header), 4th transmission: 'ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ' (ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ is the encryption key, and after the 65th transmission, it is transmitted from the 65th character to the last. '(Key transmission end header).

  The communication device 1 includes a reception unit 11 that receives radio waves in the wavelength region of broadcast waves, a connection setting information acquisition unit 12 that acquires connection setting information from radio waves received by the reception unit 11, and a connection setting information acquisition unit 12. Using the storage unit 13 that stores the acquired connection setting information, the connection setting information acquired by the connection setting information acquisition unit 12, the communication unit 14 that connects to the relay device 2, and the connection setting information acquisition unit 12 that uses the connection setting information. Is acquired by the display unit 15 for notifying that the reception unit 11 has been acquired, the multimedia signal acquisition unit 16 for demodulating radio waves received by the reception unit 11 and acquiring multimedia signals such as audio and video, and the multimedia signal acquisition unit 16 And an output unit 17 for outputting the multimedia signal. The output unit 17 includes, for example, a speaker or a display device.

  The receiving unit 11 includes a tuner that receives broadcast waves such as FM, AM, and shortwave broadcast. The connection setting information acquisition unit 12 can acquire information multiplexed on radio waves by demultiplexing broadcast waves received by the reception unit 11. The connection setting information acquisition unit 12 acquires the connection setting information described in the RDS RT unit multiplexed by the transmitter 4 from the radio wave transmitted by the transmitter 4. For example, when the connection setting information is divided and transmitted five times, the connection setting information is acquired sequentially from the RT portion of the RDS data for five times.

  The communication unit 14 establishes communication with the relay device 2 by setting the connection setting information acquired by the connection setting information acquisition unit 12. When the communication unit 14 establishes communication with the relay device 2, the communication device 1 is included in the wireless network 5 configured by the relay device 2. Therefore, the communication device 1 can be connected to another communication terminal such as the PC terminal 3 or an external network such as the Internet 6 via the relay device 2.

  In addition, the communication device 1 includes a reset button (not shown). When the reset button is pressed, the connection setting information stored in the storage unit 13 can be discarded and restarted. In addition, the communication device 1 may convert the multimedia signal acquired by the multimedia signal acquisition unit 16 into a predetermined format and transmit the converted signal to another communication device via the communication unit 14.

An example of the operation of the connection setting system according to the embodiment of the present invention will be described using the flowchart of FIG.
First, the communication device 1 starts connection setting processing when the power is turned on or a reset button is pressed.

  In step S1, the communication unit 14 determines whether or not the storage unit 13 stores valid connection setting information. Here, the valid connection setting information is connection setting information that enables the communication unit 14 to connect to the relay device 2. Whether or not the connection setting information is valid is determined, for example, based on whether or not all information such as the SSID, the encryption method, and the encryption key is stored. If the storage unit 13 stores valid connection setting information, the process proceeds to step S5.

  If the storage unit 13 does not store connection setting information, in step S2, the connection setting information acquisition unit 12 starts processing for acquiring connection setting information from the radio wave received by the reception unit 11. At this time, the receiving unit 11 is tuned to a frequency set in advance as a reception state of the multiplexed radio wave transmitted by the transmitter 4. Alternatively, the reception unit 11 may store a frequency before tuning to a preset frequency, and return the frequency to the original frequency when the connection setting process is completed. By doing so, the communication device 1 can immediately receive the broadcast wave and stream the multimedia signal after establishing communication with the PC terminal 3 and the relay device 2.

  In step S3, the connection setting information acquisition unit 12 acquires connection setting information included in the multiplexed radio wave by demultiplexing the radio wave transmitted by the transmitter 4 and received by the reception unit 11.

  In step S4, the storage unit 13 stores the connection setting information acquired by the connection setting information acquisition unit 12. In step S <b> 5, the communication unit 14 reads the connection setting information acquired by the connection setting information acquisition unit 12 and stored in the storage unit 13 from the storage unit 13.

  In step S6, the communication unit 14 establishes a connection with the relay device 2 by performing connection setting using the connection setting information acquired in step S5, and ends.

  According to the connection setting system according to the embodiment of the present invention, it is not necessary for the communication device 1 to construct a temporary network with a PC terminal or the like that is already connected to the relay device 2, and the relay device 2 can be easily configured. Connection settings can be made.

  In addition, according to the connection setting system according to the embodiment of the present invention, it is manufactured at a low cost by being configured using the FM transmitter having the RDS function and the communication device 1 that receives the FM broadcast wave. The broadcast wave receiver can be used effectively.
