Description

The present invention relates to a broadcast receiving apparatus, and more particularly, to a broadcast receiving apparatus having an improved setting function of a data acquisition desired area used in a data broadcast service or the like.

In digital broadcasting, a data broadcasting service which is a multimedia service is performed. In this data broadcasting service, information is composed of a combination of individual media such as text, graphics, still images, video, and audio, and the broadcast receiving device synthesizes and presents these received media for viewing. When a display item is selected by a remote control operation from a person, information corresponding to the selected display item is presented.

In addition, the data broadcasting service provides a mechanism for changing the content to be displayed for each viewing area. For example, weather forecasts corresponding to the viewer's residence area, train operation status, or traffic congestion information Information can be provided.

In order to receive the provision of such services, it is necessary to set information on the area setting (prefecture area code, zip code, etc.) corresponding to the area of residence in advance in the broadcast receiving device. According to the display on the receiver setting screen, it can be set by specifying a prefecture by remote control or by entering a zip code.

Further, in the conventional home (stationary) broadcast receiving apparatus, the setting of the residential area is such that only one area (usually the residential area of the viewer) can be set. When the specifications of such a broadcast receiver for home use are applied to a broadcast receiver for a mobile body, and the user intends to receive content corresponding to the area where the user has moved, the user can use the above-mentioned residence according to the location where the user has moved. Regional settings must be made each time, setting operations such as specifying prefectures and entering zip codes become complicated, and if you do not know where you moved, you cannot set the correct residential area. There was a problem.

As a reference for solving such a problem, the following Patent Document 1 predicts an area in the direction of travel from the trajectory of its own position information, and provides provided information in consideration of the predicted area and hobby preference. A provision information receiving apparatus that performs preferential accumulation by performing efficient filtering processing and displays the provision information accumulated according to an input instruction by a user is disclosed. The provision information receiving device described in Patent Document 1 can display provision information for a predicted area, but responds to a user's request to display provision information for a predetermined area outside the predicted area. There was a problem that it was not possible.

Further, in the conventional broadcast receiving apparatus, even when a non-existing postal code is input in the above-described residential area setting, the nonexistent postal code is set as it is. In this case, since the function of presenting information on the residential area does not work effectively, there is a problem that the user misunderstands that the device has been entered without noticing that the user has input a postal code that does not exist.

Further, in the conventional broadcast receiving apparatus, when the residential area setting is changed, information stored in the nonvolatile memory, that is, residential area setting information or information used by each broadcaster in the content (for example, , The specification is such that temporary information for each receiver related to the data broadcasting service recorded for use in another data broadcasting program (or the next broadcasting program) of the same broadcaster is deleted. . Therefore, when the specifications of such a home broadcast receiving device are applied to a mobile broadcast receiving device, once the residential area setting is changed according to the movement, it is stored in the nonvolatile memory until then. Since the stored information is deleted, there is a problem that even if the information is restored to the original residential area setting, the information stored in association with the residential area cannot be used continuously.

Processing (for example, message display and voice output such as “Please input again because a non-existent postal code has been input”) is performed (step S4).
5) Then, the process returns to step S37.

On the other hand, in step S35, if it is determined that “Register in prefecture” is selected on the candidate area registration screen (see FIG. 11), the candidate area registration screen by prefecture, for example, the name of the prefecture is scrolled. Then, a process for displaying a screen for selecting a prefecture to be registered as a candidate area is performed (FIG. 9-2, step S46), and selection of a prefecture to be registered as a candidate area is accepted (step S47).

Thereafter, it is determined whether or not a completion button indicating completion of selection has been input (step S48).
) If it is determined that the completion button has been input, a process for registering the selected prefecture in the candidate area, that is, a process for newly securing and registering a storage area for information on the candidate area in the nonvolatile memory 20 is performed. Is performed (step S49), and then the input button is determined (step S5).
0), if it is determined that "next registration" has been input, the process returns to step S46, and the registration process is repeated. On the other hand, if it is determined that "registration end" has been input, the process ends.

On the other hand, if it is determined in step S35 that “Register from map screen” is selected on the candidate area registration screen (see FIG. 11), the candidate area registration screen is displayed on the map screen read from the navigation device 40. A process is performed (FIG. 9-2, step S51), and the input of the registration point on a map screen is received (step S52). Thereafter, it is determined whether or not a registration point has been input (step S53). If it is determined that a registration point has been input, a process of acquiring position information of the input point from the navigation device 40 is performed (step S54).
Thereafter, the acquired location information and the location information conversion table are collated to determine the region setting information corresponding to the input location (step S55), and the determined region setting information is used as the candidate region. In other words, a process for registering a new storage area for information on candidate areas in the nonvolatile memory 20 is performed (step S56). Thereafter, the input button is determined (step S57). If it is determined that "next registration" is input, the process returns to step S51, and the registration process is repeated. On the other hand, if it is determined that "registration end" is input, the process is performed. Finish.

On the other hand, if it is determined in step S33 that “Region setting from registration candidate area” is selected on the area setting menu screen, the process proceeds to step 58 shown in FIG.
Information on the registered candidate areas is read from 0, and the area setting screen from the registered candidate areas shown in FIG. 13 is displayed. Through this screen, the user can select a registered candidate area and input a determination button to set the area.

Thereafter, it is determined whether or not a candidate area selection / determination input has been performed (step S59). If it is determined that a candidate area selection / determination input has been performed, a process for setting the selected candidate area is performed. (Step S60). At this time, the storage area for the candidate area in the non-volatile memory 20 is switched, and then the information associated with the candidate area is stored in the selected storage area for the candidate area.

Subsequently, the input button is determined. If it is determined that the “end” button has been input, the process is terminated. If it is determined that the “next setting” button has been input, the process returns to step 59 to set the next region setting. Do.

Next, the maintenance processing operation of the nonvolatile memory 20 performed by the CPU 17A in the broadcast receiving apparatus 10A according to Embodiment (2) will be described based on the flowchart shown in FIG. This processing operation is executed when selection / determination input of the “memory maintenance” item on the setting screen of the receiving apparatus is performed.

First, it is determined whether or not a “memory maintenance” item is selected / decided in the setting screen of the receiving apparatus (step S71), and it is determined that a “memory maintenance” item is selected / decided. For example, a process for displaying the memory maintenance screen shown in FIG. 15 is performed (step S72). Through this screen, the user can select a registration candidate area for deleting information stored in each storage area secured in the nonvolatile memory 20.

Then, it is determined whether or not a registration candidate area for which information is to be deleted has been input (step S73). If it is determined that there has been a registration candidate area selection / determination input, the registration candidate area is selected for the selected registration candidate area. A process of erasing information stored in the secured storage area is performed (step S
74) Thereafter, the process proceeds to step S75. On the other hand, if it is determined that there is no selection / determination input of the registration candidate area, the process proceeds to step S75. In step S75, it is determined whether or not the “end” button has been input. If it is determined that the “end” button has been input, the process ends. If it is determined that the “end” button has not been input, the process proceeds to step 73. Return.

According to the broadcast receiving apparatus 10A according to the embodiment (2), a plurality of candidate areas that are candidates for the data acquisition desired area can be registered in advance through the candidate area registration screen.
One or more candidate areas selected from the plurality of registered candidate areas can be set as data acquisition desired areas through the area setting screen from the registration candidate areas, and the operation burden for setting can be reduced for the user. It is possible to easily change the region setting without making a change, and to set a plurality of data acquisition desired regions, thereby reducing the operation frequency of the region setting.

In addition, an area corresponding to the position information acquired from the navigation device 40 can be registered as a candidate area, and the burden of registering the candidate area by the user can be greatly reduced. It is possible to register an accurate candidate area corresponding to the position information.

In addition, even when a non-existent postal code is entered when registering a candidate area by postal code, the input completion button is not displayed, so that the completion of the input is prevented and the non-existent area is identified without the user's knowledge. It is possible to prevent information from being set as setting information for a desired area for data acquisition.

In addition, when a postal code that does not exist is input, all of the input postal codes (or a part, for example, only the corrected part or the part after the corrected part) may be deleted. The user can be informed that it has been entered, can be promptly re-entered, and the user can be informed that the entered zip code does not exist by displaying a message or outputting sound. Thus, the user can be more surely notified that a postal code that does not exist has been entered.

Further, since it is determined whether or not the input postal code exists by inquiring to the server 51 via the communication unit 22, information for determining whether or not the input postal code exists is stored in the apparatus. In addition, since it is only necessary to store the latest information in the server 51, it is always possible to make a determination based on the latest information.

Further, when a candidate area is registered through the candidate area registration screen, the storage area for the registered candidate area is secured in the non-volatile memory 20, and the area setting from the registration candidate area is performed. Information associated with the candidate area is stored in the storage area for the candidate area. Therefore, even when the region setting is changed, the information associated with each candidate region can be stored in the storage region for each candidate region, and the region setting is performed again. In this case, the information associated with the candidate area can be continuously used, and when the area setting is changed, the information stored so far can be prevented from being erased.

In addition, the information stored in the storage area for each candidate area secured in the non-volatile memory can be deleted in units of candidate areas through the memory maintenance screen, and information unnecessary for the user can be deleted in units of candidate areas. It is possible to protect user privacy appropriately.

In the embodiment (2), the selected candidate area is set in the area through the area setting screen from the registration candidate area. In another embodiment, the navigation device 40 is periodically set. If the vehicle's location information is acquired from the vehicle, it is determined whether it has moved to one of the registered multiple candidate regions, and it is determined that the vehicle has moved to one of the multiple candidate regions The area may be set for the moved candidate area.

According to such a configuration, when it is determined that the user has moved to one of a plurality of candidate regions,
Since the region setting for the moved candidate region is performed, it is possible to automatically change the region setting to the candidate point without placing an operation burden on the user for setting.
