The program stored in the storage unit 12 is executed by the control unit 13, and can be read by a computer such as a CD-ROM (Compact Disc Read Only Memory) or a USB (Universal Serial Bus) storage unit 12, for example. What was stored in the recording medium may be installed.

  The display unit 14 displays characters, images, and videos, and is, for example, a liquid crystal display device. The display unit 14 receives display data to be displayed on the receiving device 1 from the control unit 13 and the like, and displays video based on the display data, text information of data broadcasting, and the like.

  The audio output unit 15 outputs audio and is, for example, a speaker. Audio data to be reproduced by the receiving device 1 is input to the audio output unit 15 from the control unit 13 and the like, and audio, music, and the like based on this are output.

  The operation unit 16 is used for inputting a user operation, and is, for example, a touch panel device or a key device. The operation unit 16 outputs input data corresponding to the user operation to the control unit 13 or the like.

  The wireless communication unit 17 is a device that communicates with, for example, a mobile phone network base station. The wireless communication unit 17 performs bidirectional data communication with the base station. The wireless communication unit 17 receives ID information and the like from a communicable base station. The ID information can include, for example, position information of each base station. The wireless communication unit 17 outputs the received data to the control unit 13 and the like.

  The GPS receiver 18 receives radio waves from, for example, GPS satellites. The GPS receiver 18 receives radio waves from a plurality of satellites and generates position information based on the received radio waves. The GPS receiving unit 18 outputs the generated position information to the control unit 13 and the like.

The control part 13 controls operation | movement of the receiver 1, for example, is a microcomputer. The microcomputer has a CPU (Central Processing Unit) that executes a program.
For example, the control unit 13 sets a reception channel in the broadcast reception unit 11 based on input data of the operation unit 16. The control unit 13 processes the video data received by the broadcast receiving unit 11 and stored in the storage unit 12 and outputs the processed video data to the display unit 14. The control unit 13 processes the audio data in the storage unit 12 and outputs the processed audio data to the audio output unit 15. . Further, the control unit 13 processes the data broadcast data 21 received by the broadcast receiving unit 11 and stored in the storage unit 12 and outputs the processed data to the display unit 14. For example, the user can obtain program information by data broadcasting, weather and traffic information, and the like through the display unit 14.

  By the way, the information that can be distributed by data broadcasting is not technically limited to the content thereof, and any information can be distributed. In addition to broadcast program information, weather and traffic information, etc., it is also possible to transmit information about a specific region or point, for example. Then, by distributing information about a specific area or point by broadcasting, there is a possibility of activating the area.

However, when information about a specific region or point is distributed by data broadcasting, in order for the information to be used by the receiver, the receiver must operate the receiving device 1 and find out the information. Don't be. The data broadcasting data 21 is described in a markup language such as BML, and the user needs to obtain information by repeating selection according to the description.
Moreover, in data broadcasting, a large amount of data is constantly updated and distributed. In data broadcasting data, wide area information such as broadcast program information, weather and traffic information is generally used.
On the other hand, information about the specific area or point is not general data broadcasting data. Moreover, unlike wide-area information related to broadcasting, such as broadcast program information, it is not recognized to be included in data broadcast data.
In such a situation where the existence of data itself is uncertain, the user himself / herself searches for information on the specific region or point from among a large number of data broadcasting data 21 received by data broadcasting. Can't expect.

Therefore, in the present embodiment, in order to distribute information about a region or a point by data broadcasting, processing to be executed by the control unit 13 together with the information is described in the region data 25 as the data broadcasting data 21.
In the area data 25, information about the area or the point may be described in, for example, BML, and the process executed by the control unit 13 may be described in, for example, a script language.

FIG. 2 is an explanatory diagram of the data structure of the data broadcasting data 21.
The data broadcasting data 21 in FIG. 2 is composed of text described in BML, and includes regional data 25 together with weather information display data 22, traffic information display data 23, and earthquake information display data 24.
The area data 25 includes processing data 26 at a display point 56 for displaying area information, processing data 27 at a first passage point on a predetermined route to the display point 56, and processing at other second passage points.

When receiving the data broadcasting data 21 of FIG. 2, the control unit 13 allocates BML data not described as a process to be executed by the control unit 13 to the startup screen 41 based on the description, and starts the startup of FIG. Display data of the hour screen 41 is generated.

FIG. 4 is an explanatory diagram showing the arrangement of the first passage point 57, the second passage point 58, the third passage point 59, and the display point 56 included in the area data 25 of FIG.
FIG. 4 shows a highway 51 extending in the left-right direction in the figure and a general road 52 that branches from the highway 51 in the center of the figure. The end of the general road 52 is connected to the information providing area 60.

And the display point 56 is the entrance / exit of the highway 51, such as the Kawagoe interchange 53, for example. The display point 56 may be the information provision area 60.
The first passing point 57 is a point on the highway 51 near the Tokyo direction of the Kawagoe interchange 53, for example.
The second passing point 58 is a point on the highway 51 near the Niigata area of the Kawagoe interchange 53, for example.
The third passage point 59 is a point on a general road such as a Kawagoe highway connected to the Kawagoe interchange 53, for example.

  As shown in FIG. 2, in the data broadcasting data 21, position data of the first passage point 57 on the highway 51 and processing at the first passage point 57 are processed data 27 at the first passage point. Described. Specifically, in the processing at the first passage point 57, when the current position matches the position information of the first passage point 57, an area M1 is secured in the storage unit 12, and a flag value “ 1 ”is set.

  In the processing data 28 at the second passage point, position information of the second passage point 58 on the highway 51 and processing at the second passage point 58 are described. Specifically, in the processing at the second passage point 58, when the current position matches the position information of the second passage point 58, an area M1 is secured in the storage unit 12, and the flag value “ 1 ”is set.

  The processing data 29 at the third passage point has no specific description. In this case, the control unit 13 does not execute the process at the third passage point 59. When the vehicle passes through the third passage point 59, the flag “1” is not set in the area M1 of the storage unit 12. Note that the position information of the third passing point 59 on the general road may be included.

The processing data 26 at the display point 56 describes position information of the display point 56 and processing at the display point 56. Specifically, the process at the display point 56 determines whether or not the flag value “1” is recorded in the area M1 of the storage unit 12 when the current position matches the position information of the display point 56. When the flag value “1” is recorded, the content information of the region or the point is displayed. If the flag value “1” is not recorded, the process ends without displaying the content information of the area or the point.
Further, the content information of the area or point included in the processing data 26 at the display point 56 may be information on the information providing area 60 ahead of the general road in FIG.

FIG. 5 is a diagram illustrating an example of a display screen 61 that is displayed when moving from the first passage point 57 or the second passage point 58 to the display point 56 and passing through the display point 56.
In the screen of FIG. 5, as information on the information providing area 60, a festival is held, traffic regulation information, temporary parking lot information, and the like are displayed. These pieces of information are displayed in a layout according to the description of BML, for example.

  FIG. 6 is a flowchart showing a processing flow of the receiving apparatus 1 for obtaining the display of the area information of FIG. 5 from the reception of the area data 25 of FIG.

  The broadcast receiving unit 11 of the receiving device 1 receives a digital television broadcast. The broadcast receiving unit 11 receives a plurality of data broadcast data 21 received and transmitted by digital television broadcast radio waves (ST1). The broadcast receiving unit 11 stores the received data broadcast data 21 in a memory. The broadcast receiving unit 11 receives the regional data 25 of FIG. 2 as part or one of the data broadcast data 21 and stores it in the memory (ST2).

When the control unit 13 of the receiving apparatus 1 monitors the memory and detects that the area data 25 is written in the memory, the control unit 13 executes the process of FIG. 6 based on the process described in the area data 25.
The control part 13 produces | generates the screen 41 at the time of starting data broadcasting, and displays it on the display part 14 (ST3). The screen of FIG. 3 is displayed on the display unit 14.

In the received area data 25, for example, as shown in FIG. 2, a process to be executed by the control unit 13 is described.
For this reason, the control unit 13 interprets the description of the processing of the regional data 25 after displaying the data broadcasting start-up screen 41 and starts the display control processing based on the vehicle position.
Specifically, when the position information of each point in FIG. 4 is described in the processing in the received area data 25, for example, the control unit 13 starts acquiring the current position of the vehicle from the GPS receiving unit 18 ( ST4) The comparison with the position information of each point described in the area data 25 is started (ST5). The GPS receiver 18 periodically generates position information at an arbitrary time such as 1 second.

  If the acquired current position does not match the position of any point described in the area data 25, it is determined that there is a mismatch, and acquisition and comparison of the current position of the vehicle are continued (ST4, ST5).

When the acquired current position matches the position of any point described in the area data 25, the control unit 13 determines that the points match, and executes the process described in correspondence with the matching point (ST6). ).
For example, when it is determined that the current position matches the first passage point 57 in FIG. 4, the control unit 13 executes processing at the first passage point 57 described in the area data 25. The control unit 13 secures an area M1 in the storage unit 12, and sets a flag value “1” in the area M1.
If it is determined that the current position matches the second passage point 58 in FIG. 4, the control unit 13 executes processing at the second passage point 58 described in the area data 25. The control unit 13 secures an area M1 in the storage unit 12, and sets a flag value “1” in the area M1.
If it is determined that the current position matches the third passage point 59 in FIG. 4, the control unit 13 executes processing at the third passage point 59 described in the area data 25. Since there is no specific description in the processing data 29 at the third passage point, the control unit 13 does not execute specific processing.
Thus, after performing the process of the passage point determined to be coincident, the control unit 13 continues to acquire and compare the current position of the vehicle again (ST4, ST5).

After that, when the vehicle moves and reaches the display point 56 in FIG. 4, the control unit 13 determines again that they match, and executes the process described corresponding to the display point 56 (ST6).
In the process of the display point 56, the control unit 13 first determines whether or not the flag value “1” is recorded in the area M1 of the storage unit 12.
When the flag value “1” is recorded in the area M <b> 1 of the storage unit 12, the control unit 13 causes the display unit 14 to display the content information of the region or point described in the region data 25. For example, the control unit 13 causes the display unit 14 to display information on the information providing area 60 of FIG.
Thereafter, the control unit 13 continues to acquire the current position of the vehicle again. Note that the control unit 13 may end the process of FIG.

As described above, in the present embodiment, when the area data 25 is distributed by digital television broadcasting and the vehicle moves toward the predetermined display point 56, the information of the information providing area 60 can be displayed.
By digital television broadcasting in which a plurality of data broadcast data 21 are sequentially updated and distributed, regional data 25 relating to a predetermined region or point can be distributed and information on the region or point can be automatically displayed.
The user can obtain information on the area or point without searching for the area data 25 from a large number of data broadcasting data 21 distributed in large quantities.

Moreover, in the present embodiment, for example, when it can be determined that the vehicle is moving from a predetermined route such as the expressway 51 toward the display point as shown in FIG. In this case, the information is not displayed.
For this reason, when it is not necessary to display the information, for example, when returning from the information providing area 60, the information can be prevented from being displayed. This information is displayed only when the user needs information, and provision of unnecessary information can be suppressed.
On the other hand, for example, when displaying information simply by reaching the display point 56, not only when moving along a route from the predetermined passing point to the display point 56 but also when returning home from the output point, for example, The information is displayed. The user may stop the display function of the present embodiment due to annoyance.

In particular, in the present embodiment, not only the display process at the display point 56 for executing the display process, but also points on a predetermined route before reaching the display point 56 are set as the advance passage points 57 to 59, and the passage As processing at points 57 to 59, a flag is set in the storage unit 12. As a result, a plurality of passing points (routes) can be specified, and there is no need to hold an actual travel history or to verify the travel history at the display timing, and the timely display is possible.
For example, it does not occur that information passes through the display point 56 and is displayed with a delay after a while. Information can be provided at an appropriate display timing.

  Moreover, in this embodiment, the process of the several passage points 57-59 can be prescribed | regulated in the area | region data 25. FIG. In addition, since the processing at the plurality of passage points 57 to 59 is described as a separate process for each point and is described by a common process of setting a flag, a plurality of travel histories corresponding to each of the traveling histories are described. There is no need to directly check the route. With a light processing load, it can be determined whether or not the vehicle is heading for the display point 56 by any route.

  The above embodiment is an example of a preferred embodiment of the present invention, but the present invention is not limited to this, and various modifications or changes can be made without departing from the scope of the invention.

  For example, in the above embodiment, the regional data 25 constitutes one data broadcasting data 21 together with other display data by BML. In addition to this, for example, the regional data 25 may constitute one data broadcasting data 21 by itself.

  In the above embodiment, the control unit 13 determines the movement from one passing point to the display point 56 based on the area data 25. In addition, for example, the control unit 13 may determine movement from a plurality of passing points to the display point 56. In this case, a multi-bit flag corresponding to the number of passing points may be stored in the storage unit.

  In the above embodiment, the regional data 25 is distributed to the receiving device 1 as data broadcasting data for digital television broadcasting. In addition, for example, the regional data 25 may be distributed to the receiving device 1 as data broadcasting data for digital radio broadcasting, data for Internet television, or Internet radio.

  In the above embodiment, the receiving device 1 is mounted on a vehicle. In addition, for example, the receiving device 1 may be a portable playback device, a mobile phone terminal, a multi-function mobile terminal, or the like. Such a receiving apparatus 1 moves by itself when carried by a person or the like.
