In accordance with the setting screen for the automatic reception function for limited area broadcasting as shown in FIG. 2, the user sets whether to automatically receive limited area broadcasting in advance. Even if the automatic reception function is set to “do not receive” automatically, it is possible to receive a limited broadcast by performing a channel selection operation on a reception channel for the limited broadcast.

  Next, the program information storage process by the data processing unit 12 of the broadcast receiving function unit 10 will be described with reference to FIG. When the ignition switch of the vehicle is turned on, the broadcast receiving function unit 10, the navigation function unit 20, and the monitor 30 are in an operating state, and the data processing unit 12 starts the process shown in FIG. Here, a description will be given assuming that the automatic reception function is set to “automatic reception”.

  First, it is determined whether or not the own vehicle is located in a region-restricted broadcast reception area (S100). When the vehicle is located in the area-limited broadcast area, the navigation processing unit 23 specifies the area-limited broadcast reception channel, and the navigation processing unit 23 instructs the digital television tuner 11 to select the area-limited broadcast reception channel. In addition, the digital TV tuner 11 selects a reception channel for area-limited broadcasting in response to the channel selection instruction. Here, when the area-limited broadcast is received by the digital TV tuner 11, it is determined that the own vehicle is located in the area-receivable area of the area-limited broadcast, and when the area-limited broadcast is not received, It is determined that it is not located in the limited broadcast receivable area.

  When the area limited broadcast is received, the determination in S100 is YES, and then it is determined whether or not the received broadcast has POI data (S102). Specifically, it is determined whether or not the facility information (POI data or the like) representing the facility included in the broadcast program is included by receiving the data broadcast.

  If the facility information is not included in the data broadcast, the determination in S102 is NO and the process returns to S100.

  If the facility information is included in the data broadcast, the determination in S102 is YES, and the data broadcast is then organized into a POI data format (S104).

  FIG. 4 shows a configuration example of the POI data format. As shown in the figure, the POI data format includes a program identifier for identifying a broadcast program, facility classification information (POI category) included in the broadcast program, location data of the facility included in the broadcast program, and a fixed period (30 minutes). ) In each item of the number of broadcasts.

  Here, in order to store the received facility information in the program information database 13 in accordance with the POI data format, the program identifier for identifying the broadcast program from the facility information, the facility classification information (POI category) included in the broadcast program, the broadcast The location data of the facilities included in the program is extracted, and when the same broadcast program is broadcast within a certain period (30 minutes), the number of broadcasts within the certain period (30 minutes) is counted.

  Next, the POI data received according to the POI data format is stored in the program information database 13 (S106). Specifically, the data organized in S104 is stored in the program information database 13 according to the POI data format.

  The above processing is repeatedly performed, and facility information representing facilities included in the broadcast program of the area limited broadcast is stored in the program information database 13.

  If the vehicle is out of the area-restricted broadcast reception area and the area-restricted broadcast is not received, the determination in S100 is NO and the data in the program information database 13 is cleared (S108). That is, all data stored in the program information database 13 in S106 is deleted.

  When the vehicle is again located in the area-receivable area receiving area and the area-restricted broadcast is received, the POI data included in the area-restricted broadcast data broadcast is accumulated in the program information database 13. It becomes like this.

  The navigation processing unit 23 according to the present embodiment displays on the display 31 a map screen in which icons (display bodies) representing facilities included in a broadcast program are superimposed on a map based on POI data stored in the program information database 13. Execute the process.

  FIG. 5 shows a flowchart of this process. When the ignition switch of the vehicle is turned on and the navigation function unit 20 is activated, the navigation processing unit 23 starts the process shown in FIG.

  First, the current location map is read (S200). Specifically, the current position is specified from the current position information input from the GPS processing unit 21, and a map around the current position is acquired from the map information database 22.

  Next, the program information database 13 is read (S202). If no POI data is stored in the program information database 13, the process returns to S200 although not shown.

  If POI data is stored in the program information database 13, then the type and size of the POI icon are determined (S204). The type of POI icon is determined according to the POI category, and the size of the POI icon is determined according to the number of broadcasts within a certain period. Note that the POI icon size is determined to increase as the number of broadcasts increases.

  Next, a map screen in which the POI icons of the facilities included in the program information database 13 are superimposed on the map around the current position is displayed on the display 31 (S206). In addition, a vehicle position mark indicating the vehicle position and information indicating that automatic reception is being performed when the automatic reception function is set to automatic reception are also displayed on the map.

  FIG. 6 shows a display example of this map screen. As shown in the figure, an icon representing an art museum, a temple, a park, and a store, and its name are displayed on the map in an overlapping manner. Also, the number of broadcasts is higher in the museum than in the park, and the size of the icon is displayed in the museum is larger than that in the park. In the upper right of the screen, a “receiving” display indicating that the automatic reception function is set to “automatic reception” is shown.

  Next, it is determined whether or not POI has been selected (S208). Specifically, it is determined whether or not a POI icon on the map screen has been selected by the user.

  When the POI icon on the map screen is selected and operated, the determination in S208 is YES, and then the program identifier is sent to the data processing unit 12 (S210). Specifically, the program identifier of the broadcast program including the facility represented by the POI icon that has been selected is transmitted to the data processing unit 12. For example, when a temple shown in FIG. 6 is selected, a program identifier of a broadcast program including the temple that has been selected is transmitted to the data processing unit 12.

  When the data processing unit 12 in this embodiment receives a program identifier of a broadcast program including the facility represented by the POI icon that has been selected and operated from the navigation processing unit 23, the data processing unit 12 determines whether or not the broadcast program is being broadcast. If it is determined that the program is being broadcast, video display processing for displaying the video of the broadcast program is performed.

  FIG. 7 shows a flowchart of this video display process. When the broadcast receiving function unit 10 is in the operating state, the data processing unit 12 starts the processing shown in the figure.

  First, it is determined whether a program identifier has been received (S300). It is determined whether or not the program identifier of the broadcast program including the facility represented by the selected POI icon has been received from the navigation processing unit 23.

  When the program identifier is not received from the navigation processing unit 23, the determination in S300 is NO and the determination in S300 is repeated.

  When a program identifier is received from the navigation processing unit 23, the determination in S300 is YES, and then it is determined whether or not the corresponding broadcast program is being broadcast (S302). Specifically, it is determined whether or not the corresponding broadcast program is being broadcast based on whether or not the program identifier received from the navigation processing unit 23 is the same as the program identifier of the broadcast program being broadcast.

  When the broadcast program including the facility represented by the POI icon selected and operated by the user starts, the program identifier received from the navigation processing unit 23 is the same as the program identifier of the broadcast program being broadcast. YES, and the display on the display 31 is switched to an area-limited broadcast image (S304). Specifically, instead of the map screen, the video of the broadcast program of the area limited broadcast including the facility represented by the selected POI icon is displayed on the display 31.

  FIG. 8 shows a display example of broadcast video when the temple shown in FIG. 6 is selected and operated. As shown in the figure, the video of the broadcast program of the area limited broadcast is displayed.

  If the program identifier received from the navigation processing unit 23 is different from the program identifier of the broadcast program being broadcast, the determination in S302 is NO and the process returns to S300. However, when a broadcast program including the facility represented by the selected POI icon is started, the program identifier received from the navigation processing unit 23 and the program identifier of the broadcast program being broadcast are the same, so the determination in S302 Becomes YES, and the video of the broadcast program including the facility represented by the selected POI icon is displayed.

  When the vehicle is out of the area-restricted broadcast receivable area and the area-restricted broadcast is not received, all data stored in the program information database 13 is erased by the process of S108 shown in FIG. As described above, when all data in the program information database 13 is deleted, the navigation processing unit 23 hides the POI icon displayed based on the program information database 13. That is, the POI icon is hidden and the POI icon cannot be selected.

  According to the configuration described above, the facility information representing the facilities included in the broadcast program upon reception of the data broadcast is stored in the program information database 13 and included in the broadcast program based on the facility information stored in the program information database 13. When the display means displays a map screen on which the display body representing the facility to be displayed is superimposed on the map and it is determined that this display body has been selected, a broadcast program including the facility represented by the selected display body is displayed. It is determined whether or not the broadcast program including the facility is being broadcasted, and when it is determined that the broadcast program including the facility is being broadcast, the video of the broadcast program including the facility is displayed on the display means. That is, it is possible to receive only a broadcast program including the facility selected by the user operation and display the video.
