Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information transmitting apparatus (external transmitting station) for transmitting dedicated character information to an individual receiver by using radio waves of FM character multiplex broadcasting and the above transmission. The present invention relates to an information receiving device (car navigation device) that receives and displays the displayed character information.

[0002]

2. Description of the Related Art Conventionally, there is, for example, a so-called "visible radio" in character multiplex broadcasting by FM radio waves and the like. In the information transmitted in the character multiplex broadcasting, one screen having a fixed format (for example, two lines of 15 characters per line) is set as one page, and one page is composed of a plurality of pages. It

[0003]

However, in the conventional character multiplex broadcasting using FM radio waves or the like, only characters other than the prescribed characters can be transmitted. Therefore, for example, the location information is transmitted together with the facility information to the car navigation device or the like, and the map is transmitted. There is a problem that the position and route cannot be displayed above.

The present invention has been made in view of the above-mentioned conventional problems, and it is an object of the present invention to provide an information transmitting apparatus and an information receiving apparatus capable of displaying facility information as well as position information by using character multiplex broadcasting. Has an aim.

[0005]

According to the invention of claim 1, FIG.
As shown in FIG. 2, the character information receiving device 2 uses a radio wave of character multiplex broadcasting that transmits a character string composed of a predetermined displayable character in a fixed format composed of a header part and an information content part. In the information transmitting apparatus 3 for transmitting to the control information adding means 10 for adding the control character information for controlling the display of the position on the map to the header portion when the display control code is converted into the displayable character.
And a transmission means 11 for transmitting the display information to which the control character information is added.

According to a second aspect of the present invention, a character string composed of predetermined displayable characters is used as a header part and an information content part.
In the information receiving device 2 which receives the character information transmitted from the external transmitting device 3 by using the electric wave of the character multiplex broadcasting transmitted in a fixed format consisting of When the header is displayed, the control character information for controlling the display of the position on the map is the above header.
Receiving means 12 for receiving the display information added to the part ,
A display means 13 for displaying the received display information and a display control means 14 for converting the control character information into a display control code and controlling the display position on the map based on the display control code are provided. It is characterized by that.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. 1 to 5 are diagrams for explaining an information transmitting apparatus and an information receiving apparatus according to an embodiment of the present invention, FIG. 1 is a configuration diagram showing the transmitting apparatus and the receiving apparatus of the present embodiment, and FIG. FIG. 3 is a diagram showing an example of information transmitted by the transmitting device, FIG. 3 is a flowchart diagram for explaining the operation of the device of the present embodiment, and FIGS. 4 and 5 are diagrams showing examples of display screens of the receiving device.

In the figure, reference numeral 1 denotes a broadcasting apparatus for performing character multiplex broadcasting by FM broadcasting, and the broadcasting apparatus 1 is
A receiving device (navigation device) 2 that receives and displays textual information, a transmitting device 3 that wirelessly transmits information to the receiving device 2, and an input device 5 that inputs information to the transmitting device 3 via a telephone line 4 or the like. It has and.

Data of the format shown in FIG. 2, for example, is input to the transmitting device 3 from the input device 5.
The above data indicates the latitude and longitude of the destination, and includes a header 8 including control character information for controlling the display of the position on the map.
And content 9 of the information.

Next, the operation of the apparatus 1 of this embodiment will be described with reference to FIG. The information transmitted from the transmitting device 3 is received by the receiving device 2 (step S1),
The control character information (for example, “3502161351212”) including the displayable characters of the header 8 is read (step S2). The control character information is not limited to numbers, as a matter of course.

Next, the control character information "350216" is given.
"1351212" is converted into a control code for controlling the display of the position on the map based on a predetermined conversion rule (step S3).

Then, the control code and the information content 9 are sent to the display 6 of the receiving device 2 (step S
4) The position information is displayed at the coordinates on the map according to the code together with the content 9.

Here, based on FIGS. 4 (a) to 4 (f),
The display operation on the display 6 will be described. First, by touching the menu key, the information menu screen shown in FIG. 4A is displayed. Then, after selecting "1: leisure facility", the area selection screen is displayed by touching the set key (see (b) in the same figure). After selecting the area as above,
The genre selection screen is displayed (see (c) in the figure) and "3.
After selecting "Aquarium", a list of facility names and introductory data is displayed (see Figure 5 (a)).

By selecting a desired facility (for example, "Kaiyukan") from the above list, the content 9 of the information shown in FIG. 2 is displayed on a predetermined page (see FIG. 2B). And
By touching the "next page" key, the location of the facility based on the above control code, the route from the current location, the name, the location of the parking lot, etc. will be displayed on the map screen (Fig.
(See (c)).

As described above, since the control character information is added to the information header 8 and the control character information is converted into the display control code, the position data on the map is transmitted using the character broadcast. Therefore, the above broadcast can be used not only for the teletext receiver but also for the navigation device of the automobile.

[0016]

As described above, according to the present invention, the information transmitting device adds the control character information consisting of the displayable characters for controlling the display of the position on the map to the header part , and the information receiving device controls Since the display position on the map is controlled based on the control character information added to the header portion , it is possible to provide the information to the character information display device by using the character broadcast and to the car navigation device. Location information is provided along with facility information to locate on the map,
There is an effect that the route etc. can be displayed.
