The course code is transmitted by a destination such as a facility or a place related to the transmission information in a predetermined order. This is a code indicating that the receiving device 2 can set a specific traveling course to be performed. The transmitting device 3 includes transmitting means for transmitting the information to which the course code is added to the receiving device 2.

The header 8 of the information received by the receiving device 2 includes "fm os os" as a source (broadcasting station name) of the information.
"aka Miel Radio" has been recorded. As a type code for identifying the type of information content, "D-INF
“O:” further records an index code following the type code. This means that the content of the text is "F. drive information" of the main menu shown in FIG. 4 and has the predetermined characteristics indicated by the index code.

The index code is set according to the rules shown in FIG. Specifically, when the content (attribute) of the body of the page is a program title or a notification from a broadcast station, a four-character space (“space”) is added as the index code.

When the content (attribute) of the body of the page is a submenu with respect to the main menu shown in FIG. 4, "MENU" is added as the index code.

The contents (attributes) of the body of the page
Is the information content of the program selected on the menu page, the first character (leftmost) from the left of the above index code is added with a selection item of an alphabet character designating the program on the menu page.

The contents (attributes) of the body of the page
Is the title of the program, "-" is related to the same object (event, facility, etc.) as the information content of the other pages. Each is added to the second character.

The contents (attributes) of the body of the page
Is "s" when writing to the storage device on the receiving device side is specified, and "space" when writing to the storage device is not specified, a series of facility information of the same type, When the event information is such that a destination such as a facility or a place related to the information can be set as a specific traveling course via a predetermined order, the course code “c” is the third character from the left of the index code. Respectively.

The contents (attributes) of the body of the page
Is “(numerical)” indicating the number of remaining information pages when the information is a part of the information over a plurality of pages, and “*” or “0” when the information is the first page from the left of the above index code. It is added to the fourth character.

On the other hand, the last page of the program is shown in FIG.
As shown in the figure, an event code page is provided for displaying the type code and a telephone number for specifying an event, facility, or the like related to the information content of the program, and for example, F1 is “Suma Beach Aquarium”. Shows the phone number of “en”. Note that a code “NaviCode” indicating that the page is an event code page is added to the header of this page.

Next, the operation of the receiving apparatus 2 of the above embodiment will be described mainly with reference to FIGS.

When a predetermined frequency is received and a program is selected and displayed from the menu (steps S1 to S2), it is detected that no switch operation is performed and that the vehicle is stopped due to the operation of the parking brake. In this case, the display content is updated according to the update of the received information content (steps S3 to S5).

When the switch operation is performed in step S3, the switch operation does not set the destination for instructing the display of the traveling course guide (step S3).
6) If the instruction is to change the receiving broadcasting station, the instruction station is selected (steps S7 to S8). If the instruction is to change the display content, the display is updated according to the operation. (Steps S9 to S10) Further, if the instruction instructs the audio output of the received information, the character information is converted into audio and output from the speaker 28 (step S9).
11 to S12). When the switch operation is not any of the above operations, a predetermined process corresponding to the operation is performed (Step S13), and the process proceeds to Step S1.

When an operation for instructing the setting of the destination for performing the traveling course guidance is performed in step S6,
It is determined whether or not the event code (telephone number) is present on the displayed page (step S14). If the event code is not detected, a predetermined message ("Destination cannot be set with this information") is issued. A predetermined time is displayed (step S15), and the above-mentioned step S1 is performed.
The processing shifts to.

In step S14, when a predetermined event code is detected on the displayed page and there is a course code "c" indicating that the page can be set as the specific traveling course (step S1).
6), the selection screen shown in FIG. 19 is displayed, and a selection is made as to whether the received information is to be displayed alone as facility and event information or to be displayed as guidance as traveling course information (step S17).

When the display as the driving course information is selected (step S18), the correspondence between the index codes "F1", "F2", "F3", and "F4" and the telephone numbers on the last page. The destinations are "Suma Beach Aquarium", "Kaiyukan", "Osaka Prefectural Fisheries Experimental Station",
The location data of "Wakayama Marina City" is the above CD-R
Read from the OM 21 and based on this position data,
A traveling course around each of the facilities is formed, and the traveling course is displayed on the display 6 (step S19).
To S20).

If it is determined in step S18 that a predetermined facility or event is to be displayed as single information, the index code "F1" or "F2" or "F3" or "F4" and the last page are displayed. Based on the correspondence with the telephone number, the location data of the predetermined facility as the destination is read from the CD-ROM 21, and the traveling course to the predetermined facility is displayed on the display 6 as guidance (steps S21 to S21). S23).

In the above embodiment, a method is used in which a course code indicating that the destination related to the received information can be set as a traveling course is added to the third character from the left of the index code. The code may be added at the left end of the index code as shown in FIGS. 20 to 29. In this case, a course code “C” is added to the left end of the index code, and the second character from the left to the right end Until the above, a predetermined code is added according to the rule shown in FIG.

Thus, a series of facility information of the same type,
Along with the event information, a course code indicating that the destination related to the information can be set as a specific traveling course is added and transmitted, and when the information including the course code is received, as the traveling course information, When the display of is instructed, a series of facilities related to the received information, a traveling course passing through the event location is displayed as a guide, so a series of facilities of the same type based on the latest information,
A guide can be displayed for the traveling course around the event. In addition, it can easily cope with setting of a traveling course according to a season.

In addition, since the user can select whether to display the received information as facility or event information or as traveling course information, when the information is set as a single facility or event information, it is necessary to go to a specific facility. The most suitable course can be displayed for guidance.

[0036]

As described above, in the information transmitting apparatus according to the first aspect of the present invention, the transmission information is added with the course code indicating that the destination according to the information can be set as a specific traveling course. In the information receiving apparatus according to the second aspect of the present invention, when a course code indicating that the specific traveling course can be set is added to the reception information, the display instruction as the traveling course information is provided. On the basis of,
Since the guide of the running course is displayed, it is possible to guide the running course based on the latest information, and it is easy to change new facilities, renovated facilities, temporarily closed facilities, or seasonal changes. There is an effect that can be surely dealt with.
