When the information terminal having the outline information receives the outline information, the position and type of the outline information can be displayed on the map being displayed by a predetermined mark or the like, and the user of the information terminal can see the mark. Thus, it is possible to easily determine whether or not the content is desired, and it is possible to very easily search for the content desired by the user on the information terminal side.

Furthermore, since the individual identification code is generated on each broadcast data creation device side, the burden on the management device can be reduced.

According to the second aspect of the present invention, the data broadcasting side needs only the data amount necessary to display the icon, and the data amount is very small like the URL in the case of the Internet service. In the information terminal, the user can easily determine whether or not the content is desired by looking at the displayed icon without increasing the size.

According to the third aspect of the present invention, since the individual identification code is generated by adding the individual identifier and the maker code to the position information, the duplication of the individual identification code can be prevented. In the case where the broadcast data creation device transmits the broadcast data including a plurality of sets of the individual identification code and the summary information to the information terminal, the information amount can be reduced.

According to the fourth aspect of the present invention, the data broadcasting side needs only the data amount necessary to display the icon, and the data amount is very small like the URL in the case of the Internet service. In the information terminal, the user can easily determine whether or not the content is desired by looking at the displayed icon without increasing the size.

According to the fifth aspect of the present invention, when the individual identification code is transmitted from the information terminal to the management server along with the data specifying the broadcast data creation device via the communication line, the management server side , The number of accesses can be ascertained and managed. Therefore, if the number of accesses is analyzed for each content, for example, marketing data on the information needs of the user can be easily obtained.

Further, according to the access frequency of the address information returned from the management server to the Web server which is the contact address, the management server side charges a fee for providing the service to the Web server which provides the content. Calculation of the fee to be performed can be easily performed.

According to the sixth aspect of the present invention, by transmitting the frequency data of the broadcast wave used by the broadcast data creation device from the information terminal, the data specifying the broadcast data creation device is given to the management server. It is not necessary to separately assign a unique ID such as a maker code so as not to be duplicated for each broadcast data creation device.

According to the seventh aspect of the present invention, the management server acquires from the broadcast data creation device an individual identification code composed of a combination of position information, an individual identifier added thereto, and a maker code. Since the comparison table comparing the acquired individual identification code and the address information is stored in the storage unit, it is possible to search for and return the address information corresponding to the individual identification code received from the information terminal. .

Further, in this case, the burden on the management apparatus can be reduced when registering in the comparison table on the management apparatus side, as compared with the case where each broadcast data creation apparatus registers separately for each broadcast frequency.
