  As illustrated, the arithmetic processing unit 1 includes a user operation analysis unit 101, a navigation processing unit 102, a communication processing unit 103, and a display processing unit 104.

  The user operation analysis unit 101 receives a request from a user input to the input device 5, analyzes the request content, and controls each unit of the arithmetic processing unit 1 so that processing corresponding to the request content is executed. To do.

  The navigation processing unit 101 performs navigation processing such as obtaining the current position from the various sensors 6 to 9 and searching for a route from the current position (departure point) to the destination.

  The communication processing unit 103 performs processing related to the exchange of information between the in-vehicle navigation device 100 and the information center 300.

  The display processing unit 104 generates a command so that information requested to be displayed is displayed on the display 2.

  Returning to FIG. 1, the flow until the vehicle-mounted navigation device 100 receives information from the information center 300 will be described.

  First, the broadcast station 300 transmits a terrestrial digital broadcast signal (S100).

  FIG. 6 is a diagram illustrating a configuration of information (broadcast information A100) transmitted by the broadcast station 300. As shown in the figure, the broadcast information A100 includes video data A101 and audio data A102, but in the present embodiment, additional data A103 is further included.

  The additional data A103 includes broadcast station information A1031, broadcast date (time zone) information A1032, program name information A1033, expiration date information A1034, and the like of the broadcast program, as shown. Broadcast date / time information A 1032 is information on the date and time when the program is broadcast. The expiration date information A 1034 is information on the expiration date when the in-vehicle navigation device 100 requests the information center 400 to transmit information. Details will be described later.

  The additional data A103 may be transmitted when information used in the navigation process (or information useful for the navigation process) is included in the broadcast content. Here, the information used for the navigation process is information on a destination (region) that can be a destination or a landmark, information used for guidance, or the like in the navigation process. For example, information on specific points (regions) such as shops, hotels, restaurants, and information on events such as festivals.

  Next, processing of the terrestrial digital broadcast receiver 200 will be described. When the terrestrial digital broadcast receiver 200 receives the broadcast signal, the broadcast wave receiver 220 decodes the broadcast signal of the broadcast station selected by the user from the received broadcast waves, and then sends it to the AV controller 230. Output.

  The AV controller 230 outputs an audio signal and a video signal to the speaker 260 and the display 270.

  On the other hand, when the additional data A103 is included in the signal output from the broadcast wave receiver 220, the main control unit 231 creates program information A200 from the additional data A103, and stores the created program information A200 in the memory card 500. The program information processing unit 232 is instructed to record.

  In response to this, the program information processing unit 232 extracts broadcast station information A1031, broadcast date information A1032, program name information A1033, and expiration date information A1034 from the additional data A103, and as shown in FIG. Program information A200 is created. And it records on the memory card 500 via the information recording device 250 (S110).

  If the same program information A200 has already been recorded on the memory card 500, the program information processing unit 232 does not need to record again.

  Thus, the program information A200 is stored in the memory card 500.

  On the other hand, if the broadcast content includes information that can be used for navigation, the broadcast station 300 transmits information related to the information to the information center 400 (S105).

  FIG. 8 is a diagram showing a configuration of information (content information A300) transmitted from the broadcasting station 300 to the information center 400.

  As shown in the figure, the content information A300 includes, for each broadcast date and time A302 in units of programs, information A304 used for navigation processing related to a time zone A303 in the program and stores, places, etc. appearing in that time zone. ing. Here, the information used for the navigation processing includes the name of the store / place; location information such as address, telephone number, latitude / longitude; traffic information around the store / place; image information of the store / place, etc. It is done. Below, the case where position information is mainly included is demonstrated.

  Since the information center 400 receives the content information A300 for each broadcasting station 300, the content information A300 for each broadcasting station 300 is stored in the storage device of the information center 400.

  That is, referring to the content information A300 stored in the information center 400 and searching using a broadcasting station and a broadcasting time zone as a key, position information A304 such as a store, a place, etc. broadcast in a program in the broadcasting time zone is obtained. Will be.

  Next, processing (S130, S140) in which the vehicle-mounted navigation device 100 receives information from the information center 400 will be described.

  As described above, the memory card 500 is configured to be removable from the information recording device 250 of the terrestrial digital broadcast receiver 200. Therefore, the memory card 500 storing the program information A200 is removed from the terrestrial digital broadcast receiver 200 by the user and inserted into the memory card reading device 11 of the in-vehicle navigation device 100.

  FIG. 10 is a flowchart showing a processing flow in which the in-vehicle navigation device 100 receives information from the information center 400.

  This flow is started when the vehicle-mounted navigation device 100 is turned on or in response to a request from the user.

  First, the communication processing unit 103 creates key information A400 (S202). The key information A400 is information used for searching the information center 400 for information to be transmitted to the in-vehicle navigation device 100 from the content information A300.

  Specifically, the communication processing unit 103 accepts selection of a program from the user and creates key information A400 for the accepted program.

  At this time, the communication processing unit 103 displays a program selection reception screen 501 on the display 2 via the display processing unit 104 as shown in FIG. That is, the communication processing unit 103 extracts the program name information A203 from the program information A200 recorded on the memory card 500, and displays the list on the display 2 as indicated by 504. At this time, for easy understanding by the user, the broadcast date and time may be displayed with reference to the broadcast date and time information A202.

  The communication processing unit 103 refers to the expiration date information A210 and does not display a list of programs whose expiration date has passed on the screen. Alternatively, the communication processing unit 103 may instruct the memory card reading device 11 to delete the program information A200 whose expiration date has passed from the memory card 500. In this way, it is possible to avoid receiving old information.

  On the screen 501, a selection icon 510 is displayed on the screen so that the user can select a desired program. In addition, all programs recorded on the memory card 500 can be selected by a button 502.

  The communication processing unit 103 accepts selection of a program via the input device 5. Then, broadcast station information A201 and broadcast date information A202 of the program selected by the user are extracted from the program information A200, and key information A400 is created as shown in FIG.

  Then, the communication processing unit 103 transmits the created key information A400 to the information center 400. Further, the information center 400 is requested to extract necessary information from the content information A300 based on the key information A400 and to transmit the extracted information to the in-vehicle navigation device. (S204).

  When receiving the key information A400 from the in-vehicle navigation device 100, the information center 400 creates information to be transmitted to the in-vehicle navigation device 100.

  Specifically, referring to the stored content information A300, the location information A304 of the shop or place specified by the broadcast station information A401 and the broadcast date / time information A402 included in the key information A300 is extracted.

  And the positional information A304 of the extracted specific point is transmitted to the vehicle-mounted navigation apparatus 100.

  The communication processing unit 103 of the in-vehicle navigation device 100 receives information from the information center 400. Then, the received location information A304 of the specific point is stored in the map data storage device 3.

  Thus, the information on the specific point stored in the map data storage device 3 is used for various navigation processes.

  For example, the navigation processing unit 102 uses position information of a specific point received from the information center 400 in the point search in the route search destination setting (S210). That is, when a point search request is made by the user, the navigation processing unit 102 displays a point search screen 601 on the display 2 via the display processing unit 104 as shown in FIG.

  In the point search screen 601, as shown in the figure, in addition to the mode 602 for searching for a point such as “From favorite”, “From registered place”, “From address”, etc., a point introduced in a terrestrial digital broadcast program A mode 603 for searching from a region or the like is displayed.

  Then, the navigation processing unit 102 accepts selection of any mode. When the mode 603 for searching from a point or region introduced in a digital terrestrial broadcast program is selected, the navigation processing unit 102 reads information from the information center 400 from the information stored in the map data storage device 3. The received information (information such as a store introduced in a digital terrestrial broadcast program) is extracted and displayed on the display 2 as a list 603.

  In addition, the navigation processing unit 102 displays a selection icon 605 and accepts selection of a search target point. At this time, when the information received from the information center 400 includes image information (moving image information) of the point, the image may be displayed. Information 604 indicating which program was introduced may be displayed.

  When a specific point is selected, the navigation processing unit 102 searches for a route from the current position by setting the point as a destination. Then, route guidance is performed using the searched route.

  The embodiment of the present invention has been described above.

  According to the above embodiment, the in-vehicle navigation device can efficiently receive information.

  That is, the in-vehicle navigation device 100 receives details such as the location information of the store introduced in the program from the information center 400 that holds information for navigation processing, not from the terrestrial digital broadcast receiver 200. Therefore, it is possible to avoid the inconvenience of receiving useless information that is not used for navigation processing.

  The key information A400 is created based on the program selected by the user. Therefore, only information related to the user's request can be received from the information center 400.

  Even if the broadcaster has detailed information such as the store address, only the appearance of the store and the contents of the menu may be broadcast in actual broadcasting. In this case, the location information of the store necessary for navigation cannot be obtained only from the broadcast information, and the needs of the user who wants to go to the store cannot be answered. According to the embodiment, the broadcast station 300 transmits detailed location information of the store to the information center 400. Then, the in-vehicle navigation device 100 receives detailed store location information from the information center 400. Therefore, even when detailed information cannot be obtained by broadcasting, it is possible to answer the user's needs to go to the broadcast store.

  The above embodiment can be variously modified within the scope of the gist of the present invention.

  In the above embodiment, the program information A103 of the memory card 500 includes the broadcast station information A1031, broadcast date information A1032, program name information A1033, and expiration date information A1034. However, the present invention is not limited to this, and when the user checks a program during the program display, information to that effect may be included.

  In such an embodiment, the main control unit 230 receives a check instruction from the user via the input device 240 while the broadcast program is being displayed on the display 270 of the terrestrial digital broadcast receiver 200. If checked, the main control unit 230 adds information A204 indicating that the check has been made to the program information A200 and records it in the memory card 500. FIG. 14 is a configuration diagram of the program information A200 recorded on the memory card 500 in such a case.

  FIG. 13 shows a screen 401 when a check instruction is received from the user when the restaurant introduction program 402 is displayed on the display 270 of the terrestrial digital broadcast receiver 200. As shown in the figure, a message such as “I checked this program” is displayed.

  Further, on the program selection receiving screen 501 displayed when the in-vehicle navigation device 100 creates the key information A400, as shown in FIG. 15, a display that can determine whether or not the user has checked the program is displayed. You may make it do.

  Specifically, the communication processing unit 103 refers to the check information A204 of the program information A200 and performs the display 605 indicating the presence / absence of the check in FIG.

  In this way, when the user selects a program, it is possible to easily remember a program on which a particularly interested store or the like was broadcast. Then, it is possible to receive information from the information center 400 by focusing on the location information of the store or the like.

  Also, the checked time may be recorded in the memory card 500. Then, the communication processing unit 103 of the vehicle-mounted navigation device 100 may transmit key information A400 including the checked time to the information center 400. Then, the information center 400 may extract the location information A304 of the store broadcast at the checked time with reference to the broadcast date / time information A303 and transmit it to the in-vehicle navigation device 100.

  In this way, the in-vehicle navigation device 100 requests and receives only information on stores and the like that the user is interested in from the information center 400, so that the reception efficiency is improved. That is, information can be received not on a program basis but on a content basis.

  In the embodiment, all the program information A200 created from the additional data in the broadcast signal is recorded in the memory card 500. Not limited to this, only the selected program information A200 may be recorded in the memory card 500.

  For example, the main control unit 231 records in the memory card 500 only the program information A200 of a program related to a program, a broadcast time zone, and a content set in advance by the user via the input device 240.

  In this way, since only the program information A200 of the user's favorite program such as a travel program or a cooking program can be recorded in the memory card 500, the storage capacity can be suppressed. In addition, since a list of programs selected according to the user's preference is displayed on the program selection reception screen when creating the key information, the selection becomes easy for the user.

  The main control unit 231 may record only the program information A200 of the program checked by the user on the memory card. Even in this case, the storage capacity recorded in the memory card 500 can be further suppressed.

  In addition, when the storage capacity of the memory card 500 is full (or exceeds a predetermined storage capacity), the main control unit 231 may delete the oldest information in order. Further, the program information A200 of programs that have not been checked by the user may be deleted from the oldest.

  In the above embodiment, when creating the key information A400, the communication processing unit 103 reads the program information A200 of the memory card 500 via the memory card reading device 11. However, the recorded contents of the memory card 500 may be read in advance into the map data storage device 9. The communication processing unit 103 may read the program information A200 from the map data storage device 9 when creating the key information A400. For example, when the memory card 500 is inserted into the memory card reading device 11, the recorded content can be read and stored in the map data storage device 9 automatically or in response to a user request.

  In the above-described embodiment, information is exchanged between the terrestrial digital broadcast receiver 200 and the in-vehicle navigation device 100 via the memory card 500. However, the present invention is not limited to this, and information may be exchanged via a wired or wireless communication network.

  For example, the terrestrial digital broadcast receiver 200 may be installed in the user's house, and the program information may be transmitted to the in-vehicle navigation device 100 via a wireless LAN. Further, the communication processing unit 103 of the in-vehicle navigation device may request the program information A200 from the terrestrial digital broadcast receiver 200.

In the above embodiment, the additional data A103 of the broadcast information A100 transmitted from the broadcast station 300 includes the broadcast station information A1031, broadcast date information A1032, program name information A1033, and expiration date information A1034. Not limited to this, the additional data A103 may not include any of these. For example, when the broadcast station information A1031 is not included, the main control unit 231 of the terrestrial digital broadcast receiver 200 determines the broadcast station from the setting of the tuner 221 and creates the broadcast station information A201 of the program information A200. May be. If the broadcast date / time information A1032 is not included, the main control unit 231 may determine the broadcast date / time from its own timer and create the broadcast date / time information A202 of the program information A200. The broadcast wave receiver 220 and the AV controller 230 of the receiver 200 may be housed in one housing. When the above-described embodiment is mounted on a vehicle, the AV controller 230 may be incorporated in, for example, a navigation device.

  Moreover, the terrestrial digital broadcast receiver 200 and the in-vehicle navigation device 100 may be integrally provided in one housing. Then, hardware resources such as a CPU, a memory, and an input / output device may be shared.

  The navigation device may be a vehicle-mounted navigation device or a navigation device other than the vehicle-mounted navigation device.
