As shown in FIG. 7, when event information is sent from information provider 1 to both FM broadcasting stations 2A and 2B, both FM broadcasting stations 2A and 2B This event information is received by the broadcasting stations 2A and 2B (step S1). At this time,
The location information (latitude and longitude) of the information provider 1 and a telephone number, a facsimile number, and an Internet URL (Uniform Resource Locator) are also accepted as inquiry destination data.

After the position information is converted into position codes in both FM broadcasting stations 2A and 2B, it is determined whether or not the position codes are already registered in the databases of both FM broadcasting stations 2A and 2B ( Step S2) If the result of this determination is NO, it can be determined that there is no position code already registered, so that the process proceeds to step S6 to be described later, after which an individual identification code is assigned and registered in the database.

On the other hand, if there is an already registered position code, it is determined whether or not the newly received information is update information of the already registered information (step S3). If the result is YES, that is, the update information of the already registered information, the already registered information is overwritten with the update information and updated (step S4), and the determination result is NO, that is, if the update information is not the update information. The individual identification code assigned to the position code is checked (step S5), the individual identification code is assigned (step S6), and the position code of the information provider 1 and the contents of the detailed event information are checked. An information table consisting of both FM broadcast stations 2A,
It is stored in the 2B database (step S7).

Subsequently, after the processing in step S7, the processing shifts to step S8 after the processing in step S4 described above, and outline information representing the outline of the event information is created, and the position code, the database designation code, and the individual identification code are created. A code is added (step S8), and the center-side reference table (FIG. 4) including the database designation codes and corresponding inquiry destinations such as telephone numbers and URLs.
Is created and stored in the database (step S9), and the summary information and the center-side reference table are FM multiplex broadcast (step S10), after which the operation ends.

Next, the operation of the car navigation system 5 will be described. As shown in FIG.
The multiplexed summary information and the center-side reference table are received (step S11), and the received summary information and the terminal-side reference table (see FIG. 5) based on the center-side reference table are stored and stored in the storage unit 14 (step S1).
2) It is determined whether or not there is a request for calling the detailed contents by the user (step S13). If this determination result is NO, step S1 is performed until the determination result becomes YES.
The determination of 3 is repeated.

On the other hand, if the decision result in the step S13 is YES
If so, the inquiry destination (telephone number or URL) corresponding to the database designation code selected by the user is read from the terminal-side reference table stored in the storage means 14 (step S14), and the telephone control unit 17 Then, the mobile phone 18 automatically dials the inquiry destination (step S15).

When a communication line is connected to one of the FM broadcasting stations (here, the FM broadcasting station 2A), the position code and the individual identification code are delivered from the car navigation system 3 to the FM broadcasting station 2A ( Step S16) On the FM broadcast station 2A side receiving this, the database is searched based on the position code and the individual identification code, and the corresponding event information is called.

Further, when the detailed contents of the called event information are transmitted to the car navigation 3 side, the detailed contents of the event information are received by the CPU 13 via the mobile phone 18 and the telephone control unit 17 (step S17). ), The display unit 15 is controlled to display the received content (step S18), and then the operation ends.

As described above, the FM broadcast stations 2A and 2B create summary information indicating the summary of the event information, as well as the database designation code for referring to the inquiry destination regarding the summary information, the position code and the individual identification. A code is added to the summary information, and the summary information, the position code, the database designation code, and the individual identification code are transmitted from the FM broadcast stations 2A and 2B.

Further, the FM broadcast stations 2A and 2B create a center-side reference table including each database designation code and each inquiry destination corresponding to the database designation code, and are transmitted from the FM broadcast stations 2A and 2B, and transmitted to the car navigation system. The terminal-side reference table based on the center-side reference table received by the third side is stored in the storage means 14, and when necessary, a desired inquiry destination is read out from the reference table and connected, and the telephone control unit 17 and the mobile phone 18 are connected. , Detailed contents of the event information are acquired on the car navigation 3 side.

Therefore, according to the above-described embodiment, the information amount of the individual identification code itself, for example, “A” is much smaller than the information amount of the telephone number or URL data corresponding to the inquiry destination. By adding the database designation code to the summary information and transmitting the information, it is possible to transmit one message from the FM broadcasting stations 2A and 2B, compared to the case where the event information includes the inquiry address such as a telephone number and a URL. This makes it possible to significantly reduce the amount of information per hit.
