Description

Broadcast receiver

The present invention relates to a broadcast receiving apparatus, and more particularly to a broadcast receiving apparatus capable of presenting a data broadcast corresponding to a region.

In digital broadcasting, a multimedia service (so-called data broadcasting service) is provided according to the viewer's residence area (that is, where the broadcast receiving device is installed). For example, weather corresponding to the viewer's residence area is provided. Information such as forecasts and election bulletins is provided.

In order to use this service, the user must set the viewer's residential area information (prefecture area code, area code, zip code, etc.) corresponding to the residential area in advance on the broadcast receiver through the menu screen, etc. For those who are unfamiliar with the setting operation, the setting operation is troublesome and an incorrect setting may be performed. Furthermore, when the broadcast receiving apparatus is configured to be portable or to be mounted on the vehicle, there is a problem that the user has to reset the viewer residence area information every time the user moves.

In order to solve such a problem, the following patent document 1 converts current position information acquired from an information communication terminal into viewer residence area information and stores it in current viewer residence area information and a nonvolatile memory. There is disclosed a digital broadcast receiving apparatus that updates and records the current viewer residence area information in a nonvolatile memory when the viewer residence area information is different.

However, as in the digital broadcast receiver described in Patent Document 1, when the viewer residence area information changes, it is not always preferable to update and record the current viewer residence area information. For example, when the frequency of presentation of data broadcasts by the user is low, the update may be wasted even if it is updated every time the viewer residence area information changes. In addition, when moving near the boundary area where the viewer residence area information is switched, the viewer residence area information may be updated more frequently than necessary. In some cases, it may be desired to present a data broadcast related to a specific area without following the change in the viewer residence area information. Furthermore, since the viewer residence area information is updated and recorded in a non-volatile memory with a limited number of times of writing, if unnecessary writing is frequently performed, the deterioration of the non-volatile memory is accelerated. There was a problem.

It is composed of a microcomputer including a CPU, a ROM, and a RAM.

The navigation control unit 53 also determines the current position information (longitude / latitude data) of the determined vehicle, and the position information of the destination and the position information of the waypoint to the destination (when the destination is set) (Latitude and longitude data) is transmitted to the broadcast receiving apparatus 10C via the communication line L1. For example, when the destination setting is completed, the “data broadcasting acquisition setting” screen shown in FIG. 8 is displayed. Through this screen, data broadcasting at a predetermined point corresponding to the guidance route such as the destination is displayed. It is possible to set whether or not to acquire the data. When the “Yes” button is input on the screen shown in FIG. 8, the “Data acquisition point selection” screen shown in FIG. 9 is displayed. Through this screen, the data broadcasting at any point is displayed. It is possible to select whether to acquire data. In this case, it is possible to select “home”, “destination”, and “route point”. When the “selection complete” button is input, the position information (longitude / latitude data) of the selected point is transmitted to the broadcast receiving apparatus 10C.

On the other hand, in the broadcast receiving device 10C, when the position information of each point is acquired from the navigation device 50, the CPU 17C converts the position information of each point into the region registration information, and the converted region registration information is temporarily stored in the RAM 19. Remember. Further, the CPU 17C starts receiving the set broadcast channel, extracts data broadcast data corresponding to each area registration information stored in the RAM 19 from the received data of the broadcast channel, and stores the data in the nonvolatile memory 20 While storing in a data broadcast storage area, the process which displays on the display 32 is performed. The display 32 may be displayed on two screens, for example, one of which displays a map of a navigation and the other displays the contents of a data broadcast, or displays the contents of a data broadcast on a full screen for a certain period of time. ing. Further, when the CPU 17C detects that the route guidance to the destination has been completed, the CPU 17C performs a process of storing the area registration information stored in the RAM 19 in the area registration information storage area of the nonvolatile memory 20. .

Next, processing operations performed by the CPU 17C in the broadcast receiving apparatus 10C according to the embodiment (4) and the navigation control unit 53 in the navigation apparatus 50 will be described based on the flowchart shown in FIG. This processing operation is executed when the navigation device 50 completes setting of a destination for performing route guidance.

First, the navigation device 50 determines whether or not the destination setting is completed in step S31. If it is determined that the destination setting is not completed, the process returns to step S31, while the destination setting is completed. If it is determined that the process has been performed, the process proceeds to step S32.

In step S32, a process of displaying the “data broadcast acquisition setting” screen shown in FIG. 8 is performed, and then the process proceeds to step S33 to determine the selection button. If it is determined that the “No” button has been selected, the process proceeds to step S37, whereas if it is determined that the “Yes” button has been selected, the process proceeds to step S34. In step S34, the “data acquisition point selection” screen shown in FIG. 9 is displayed. Thereafter, the process proceeds to step S35, and it is determined whether or not the “selection complete” button has been input. If it is determined that the “selection complete” button is not input, the process returns to step S35, whereas if it is determined that the selection complete button is input, the process proceeds to step S36.

In step S36, the position information (longitude / latitude data) of the selected data acquisition point is transmitted to the broadcast receiving apparatus 10C, and then the process proceeds to step S37 to start the route guidance process to the destination.

On the other hand, in the broadcast receiving apparatus 10C, in step S38, it is determined whether or not the position information of the data acquisition point has been received from the navigation apparatus 50. If it is determined that the position information of the data acquisition point has not been received, the process proceeds to step S38. On the other hand, if it is determined that it has been received, step S
Proceed to 39.

In step S39, the conversion table stored in the ROM 18 is read out, the data acquisition point position information is converted into area registration information using the conversion table, and then the process proceeds to step S40. In step S40, the converted area registration information is temporarily stored in the RAM 19, and then the process proceeds to step S41.

In step S41, a process of displaying a reception channel setting screen for allowing the user to select a broadcast channel to be received is performed. Then, the process proceeds to step S42, where it is determined whether or not the reception channel is set, and the reception channel is set. If not, step S4
On the other hand, if it is determined that the reception channel has been set, the process proceeds to step S43.

In step S43, it is determined whether or not a data broadcast corresponding to the destination or waypoint regional registration information has been received. If it is determined that the data broadcast has not been received, the process proceeds to step S47. Proceed to S44. In step S44, a process of extracting data broadcast data corresponding to the regional registration information from the received data is performed. Then, the process proceeds to step S45, and the process of storing the extracted data broadcast data in the nonvolatile memory 20 is performed. Thereafter, the process proceeds to step S46, where the extracted data broadcast data is displayed on the display 32, and then the process proceeds to step S47.

In step S47, it is determined whether or not a guidance end signal to the destination from the navigation device 50 has been received. If it is determined that the guidance end signal has not been received, the process returns to step S43 and repeats the process. If it is determined that the end signal has been received, the process proceeds to step S48.
In step S48, a process of storing the area registration information stored in the RAM 19 in the nonvolatile memory 20 is performed, and then the process ends.

According to the broadcast receiving device 10C according to the above embodiment (4), the location information of the predetermined point acquired from the navigation device 50, for example, the location information such as the user's home, the destination, or the waypoint to the destination. Are converted into corresponding regional registration information and stored,
Data broadcast data corresponding to each area registration information can be extracted from the received data and presented. Therefore, when the navigation device 50 is used for route guidance or the like, data broadcast data corresponding to the region registration information at a predetermined point can be extracted and presented, and various information is provided to the user. It becomes possible.

In addition, since data broadcast data corresponding to the regional registration information extracted from the received data is stored, the stored data broadcast can be presented later and the contents can be confirmed.
In particular, when used for vehicles, the contents of data broadcasting related to a predetermined point can be confirmed in a safe state such as when the vehicle is stopped, and safety can be improved.

In addition, after the area registration information converted from the position information is temporarily stored in the RAM 19, the area registration information stored in the RAM 19 is stored in the nonvolatile memory 20 when the guidance to the destination is completed. The number of times the area registration information is written (stored) can be greatly reduced, and the deterioration of the nonvolatile memory 20 with a limited number of times of writing can be delayed. Note that the area registration information stored in the RAM 19 may be stored in the nonvolatile memory 20 when the ACC power is turned off or when the main power switch of the navigation device 50 is turned off, instead of when the guidance to the destination ends. Also in the broadcast receiving apparatuses according to the above embodiments (1) to (3), after the area registration information converted from the current position information is temporarily stored in the RAM 19, it is nonvolatile when the ACC power is turned off or at a predetermined timing. May be stored in the memory 20.
