Data Broadcast Reception Display Device Technical Field

The present invention relates to a data broadcast reception display device that displays reception information of a data broadcast. The present invention also relates to the reception and display of a data broadcast in a device having a function of detecting a current position, such as a car navigation device. Background art

In recent years, terrestrial VBI (Vertical Blanking Intervals) broadcasting, which broadcasts data using gaps between video and audio signals of television broadcasting, has been realized. In addition, data broadcasting via media such as terrestrial digital broadcasting, satellite digital broadcasting, and cable TV is planned. Such a data broadcast can supply data to a large number of viewers at a time by radio waves from the transmitting side, while a dedicated receiving board is mounted on a personal computer or the like from the receiving side. The advantage is that you can enjoy various types of data as long as you have it (in some cases, free of charge). On the other hand, such data broadcasting, as well as traditional television broadcast, because it is intended for unspecified number of viewers, a particular group and information for individuals in difficulty flowing les ₀

In addition, the contents of the data broadcasting, in general, unlike is the video ^force? Viewing of uninterruptedly state as in the conventional television program, once, is downloaded into the storage device, intended to be viewed on ex-post user-driven It is.

In data broadcasting, a wide variety of content capabilities such as news, weather information, traffic information, music information, shopping information, etc.? Because it is prepared, it is difficult for the viewer to download all of them once, due to the limited storage capacity of the storage device. In particular, content that makes heavy use of image data requires a dramatically larger storage capacity than content that uses only text data.

Accordingly, an object of the present invention is to provide a data broadcast receiving and displaying device capable of automatically selecting information required by a viewer among various kinds of information to be broadcast. Is to do. Another object of the present invention is to provide a data broadcast receiving / displaying device that enables a data broadcaster to provide a service as if providing information to individuals.

Still another object of the present invention is to provide a data broadcast receiving and displaying device capable of reducing the required capacity of a storage means for storing broadcast data.

By the way, a car navigation device that is mounted on a vehicle and displays a map on a display is also becoming popular. Conventional car navigation systems basically include a current position detecting means such as a GPS (Global Positioning System), a map information storing means such as a CD-ROM, and a display means for displaying a map. And provided the user with directions to the destination.

If such a car navigation device is provided with receiving hardware for receiving the data broadcast, the car navigation device functions as a data broadcast receiving and displaying device, not only as a route guidance device.

However, the content to be subjected to data broadcasting is a power that can include various kinds of information as described above, and in particular, the current position of a car navigation device changes sequentially. It is relatively difficult for users to quickly select necessary data.

Further, as described above, the broadcast data temporarily, after stored in an internal storage device, it forces ^s preferable to reading it constitutes a screen data display, mounted large-capacity storage device is an apparatus for vehicle The power to do is relatively difficult.

Another object of the present invention is to provide a data broadcasting reception display device suitable for application to a car navigation device. Disclosure of the invention

A data broadcast receiving and displaying apparatus according to the present invention includes: a data broadcast receiving unit that receives broadcast data including file attribute information related to a data file to be broadcast; File selection means for selecting a data file having a file attribute, file storage means for storing the selected data file, and data file stored in the file storage means And a display means for displaying. The file selection means, since stored in the selected file storage means only data files matching the specific file attribute, it is possible to reduce the necessary capacity of the file storage means, and not non-required data force ^s Kaku鈉Therefore, the user can quickly view the target information.

More specifically, a management file describing file attribute information of each of the plurality of data files is received together with the plurality of data files, and the file storage unit is selected by the management file and the file selection unit. And the stored data file. By holding the file attribute information of all data files in the management file collectively, it is possible to recognize the attributes of all data files simply by referring to the management file.

The file attributes include at least one of a data category (genre), an update date, an expiration date, a region, and a user attribute of each data file, and a file attribute designated by a user as the file selection condition is registered. It has the means to do. As a result, a data file having an attribute matching the file attribute registered in advance by the user can be automatically selected from the received data files. The user attributes include, for example, the gender and age of the user.

As another embodiment, a means for displaying a list of file attributes described in the management file, and a means for holding, as the file selection condition, identification information of an arbitrary data file selected by a user from the list display May be provided. This allows the user to individually select a desired data file from the list display.

The data file by using an H TM L files, the seamless connection ^mosquito? Available to Internet Bok from the display screen of the display hand stage.

According to still another aspect of the data broadcast receiving and displaying apparatus of the present invention, a map information storage unit that includes position information related to data of the data file as the file attribute, stores road map information, A current position detecting means for detecting a current position; displaying the road map information; and a position represented by the position information of the file stored in the file storing means and the current position on the map. Display means for displaying the contents of the selected file in place of the map.

A means may be provided for the user to set a range of a distance between the position represented by the position information and the current position as a file selection condition. This allows the user to specify the desired distance range.

As the file selection condition, a selection condition for acquiring a file and a selection condition for displaying a file may be separately set. This is particularly effective when the current position when the file is obtained is different from the current position when the file is displayed. In the management file, the expiration date information of each data file is described as the file attribute, and the management file may include a unit for deleting a data file stored in the file storage unit that has expired. Good. As a result, it is possible to avoid displaying information whose expiration date has passed, and to effectively utilize the storage area of the file storage means.

Said selecting means, the same data file as the data file already stored in the file storage means that force ^s desirable not selected. This prevents the same data file from being duplicated and stored in the file storage means.

Also, if it is described in the Date force ⁵ 'the management file of the data file as the file attributes, said selection means includes a data file that has already been stored in the received data file ^force? The Huai Le storing means it is the same, if the renewal date ^mosquitoes? new data file that the received, it is desirable to select the data file that the received. This ensures that you do not miss a newly updated version of the same data file.

According to another aspect, the present invention is a data broadcast receiving and displaying method for receiving broadcast data including position information related to a data file to be broadcast, and displaying the received information, wherein the method includes the steps of: Setting at least a selection condition related to a position for selectively loading a data file, collating the set selection condition with position information related to each data file received by the data broadcast, Only the data file whose information matches the selection condition is fetched into the storage device, and the fetched data file is extracted under the same or different selection condition as the selection condition. And providing a method for receiving and displaying data broadcasting. More specifically, the current position of the user is detected, the current position is compared with position information related to each data file in light of the selection condition, and only the data file that matches the selection condition is stored in the storage device. And the retrieved data file is retrieved and displayed under the same or different selection conditions as the selection conditions, and at this time, road map information is displayed and the storage device is displayed on the map. The location represented by the location information of the stored file and the current location are displayed, and the content of the selected file is displayed automatically or in response to a user's instruction in place of the map. The present invention further includes, as a right scope, a recording medium on which a computer program for realizing the above data broadcast receiving and displaying method is recorded. BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

First, a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows a hardware configuration of a data broadcast receiving apparatus according to the present invention. This is equivalent to the configuration of a normal personal computer with a data broadcast receiving function added. Actual product forms include personal computers, those incorporated in television sets, set-top boxes external to television sets, portable terminal devices, and car navigation devices described below. It is possible. The data broadcast receiving and displaying device 101 has a CPU 111 that controls the entire device by program processing, a ROM 111 that stores a control program that executes the CPU 111 ^s and necessary data, and a CPU l. 11 A RAM I 14 that provides a work area, buffer area, and temporary storage area when executing the program in 11, and a data storage device (hard disk, flash memory, etc.) that can store data in a nonvolatile manner. When,

A display 117 that displays various data such as the contents of the HTML file, a speaker 118 that outputs audio information, and an input device for the user to input instructions (for example, operation keys, touch panel, remote control) Etc.) 1 19, a data broadcast receiving section 121 which receives a data broadcast such as a television multiplex broadcast via an antenna 120, And a communication control unit 122 for controlling data communication with the unit. The communication control unit 122 is connected to, for example, a telephone line or a mobile phone via the TEL connector 123, and can access the Internet. The data broadcasting may use terrestrial waves or satellite broadcasting.

FIG. 2 shows a schematic configuration example of data received by the data broadcast receiving unit 11. The broadcast data is transmitted in the order of a plurality of data files 22 starting from the management file 21 and sequentially transmitted to the last data file 22, and then continuously or after a predetermined time interval, the same file is transmitted. The kumi strength ^{5 is} sent and repeated. The contents of any data file are updated as needed on the sending side, and files are deleted or added as needed. The data file in the present embodiment is an HTML file described in a so-called HTML language. An HTML file is a format of data obtained from the Internet WWW server, and adopting this data format enables seamless connection to the Internet. For example, it is possible to connect to a specific site on the Internet by pointing to a hot spot set in a browser screen displaying a specific HTML file obtained by data transmission.

When a file is transmitted using the gap in the television signal, each file is divided into multiple buckets and transmitted, and the receiving side reconstructs the file. In the present invention, since it is sufficient that the file is received, no detailed transmission method is described. In addition to the HTML file, the data file may include a GIF file or audio data to be captured as an inline image.

FIG. 3 shows a specific example of the management file 21 shown in FIG. The management file 21 has a file name of, for example, kanri.Ran G, and describes attribute information of each data file 22 following the file name. In the example in the figure, for each data file, its number 210, file name 211, category 212, update date 17, data size

(KB) 218, Title 219, and Region Name 216 are described. One

And HTML files, are the same Huai Le numbers ^force? Attached to other data files to be combined with this. Category 2 12 is “News” “Weather” Indicates the type of the data file, such as "S ports". Region 2 16, the data ^force? Shows the area of the object to be viewed, this is the case of "No" means that the area of interest has not been limited.

The content of the management file 21 shown in FIG. 3 is a list of items 210 to 212, 216 to 219, each with a space between them. On the receiving side, the number of items included in one file Since each is known, each item can be identified by the number of spaces after it. In this format, the data amount of the management file 21 can be minimized. Of course, the format of the management file is not limited to this, and other formats may be adopted.

Fig. 4 shows the same contents as the management file 21 in Fig. 3? An example of a management file of a different format is shown. In this example, identifiers 220 to 222 and 226 to 229 are added before each item 210 0 to 2 12, 2 16 to 219 to indicate whether the item is valid. Different from the management file. In this case, there is an advantage that the number of items in each data file may be different.

FIG. 5 shows a flowchart of a process for displaying the information table. In response to the user's instruction to display the information table, the management file is received via the data broadcast receiving unit 121 (S11), and the information table is displayed on the screen based on the management file (S12). Then, an arbitrary title instruction from the user is received (S13), and the number of the data file is stored (S14).

FIG. 6 shows a display example of the information table 60 obtained from the management file. This displays an information table 60 including the number, title, category, and region name of each HTML file included in the management file in a list format. Each HTML file number has a check box 61, and the user can individually specify the title that the user wants to see by checking the check box 61.

After checking the check box 61, the user instructs data reception and capture. FIG. 8 shows a flowchart of the process executed in response to this instruction. First, the number of the previously stored HTML file is read out (S1). Next, download all data files with numbers that match this number (S2 2) If another number remains (S23, Yes), steps S21 and S22 are repeated to download the data files of all the specified numbers. Then, if the content of the downloaded data file is to be displayed immediately in response to an instruction from the user (S24, Yes), one of the downloaded HTML files is read out and displayed by the browser ( S 25). If there is a termination instruction from the user, this processing is terminated (S26). If there is an instruction to move to the next HTML file (S27), the process returns to step S25 to display the next HTML file.

As described above, when a link to an arbitrary URL (Uniform Resource Locator) on the Internet is set on the display screen of one HTML file, the hot spot is designated (clicked). By doing so, it is possible to seamlessly connect to the Internet. If the user wants to view the downloaded data file after the processing in FIG. 8 is completed, a process equivalent to the process in step S25 in FIG. 8 may be performed.

FIG. 7 shows a display example of one HTML file (NEWS. HTM) in step S25 in FIG. In this example, the data file of N 0.1 in the information table of FIG. 6 is displayed.

In the above description, a description is given of an example in which the user designates individual titles from the information table and takes in desired broadcast data. Next, the user's ability is determined according to the genre (category) of information specified in advance. Here is an example in which automatically selects the corresponding broadcast data. For that purpose, the user needs to specify a genre or the like in advance as the information selection condition.

FIG. 9 shows an example of an information selection menu screen for setting information selection conditions, which is displayed on the display 117 in this embodiment. In this example, a region to which the user belongs (or a desired region) and a desired genre can be specified as the information selection condition. In the example shown in Fig. 14, the user selects a check box (rectangular button) corresponding to each condition by operating a key, mouse, touch panel, or the like. The check box 52 is for selecting an arbitrary number of items from a plurality of options. By default, "Nationwide" and "All" are selected. In the example of the figure Indicates a selected item in a black square. If the cancel button 55 is indicated with the condition item selected, the entry is canceled and the registration state returns to the state before the entry. By instructing the register button 54, this condition is registered, and the screen returns to the original screen (not shown) which started this screen.

An example of data reception processing executed in accordance with the information selection condition of FIG. 9 is shown in the flowchart of FIG. This process is executed in response to a user instruction or periodically. In the case of regular, it is preferable to allow the user to specify the interval.

First, a management file is found from the received broadcast data and stored in the RAM 13 and the data storage device 115 (S31). Next, the loop variable n is set to 1 (S32), and the loop processing is started.

In the loop processing, first, the attribute information (the group of items in one line in FIG. 3) of the n-th HTML file is extracted (S33). Therefore, it is checked whether “region” is specified as the information selection condition (see FIG. 9) (S34). If the area specified by the user is "nationwide", it is determined that no area is specified, and the process proceeds to step S37 described later. If a specific area other than “nationwide” is specified, check which area it is (S35). Next, it is determined whether the area matches the area described as the attribute information of the HTML file (S36). If not, the process proceeds to step S43 described later.

If the area matches, it is checked whether a genre is specified next (S37). It is determined that there is no "Ja Nruka ^s" If all "genre specified, the process proceeds to step S 3 9 which will be described later, if there is a designation of a particular genre, whether the genre is consistent with the genre of HTML Huai Le Check (S38). If not, the process proceeds to step S43 described below.

If the genre matches, it is checked whether a file having the same name as the HTML file has already been stored (S39). If not stored, the HTML file is downloaded and stored in the data storage device 115 (S40). If not stored, it is checked whether the file needs to be updated (S41). Specifically, for example, the update date of the HTML file described in the management file (Fig. 3 2 17) is compared with the update date of the stored file, and if they are different, it is determined that update is necessary. If it is determined that updating is necessary, the same file in the data storage device 115 is updated (S42), and if it is determined that updating is unnecessary, the process proceeds to step S43.

In step S43, the variable n is incremented (S43). Therefore, referring to the management file, it is confirmed whether there is a new η-th file (S44), and if not, the process is terminated. If there is, the process returns to step S33, and the above process is executed again. .

In this way, only the HTML file I le with attributes that match the user ^force? Specified condition is automatically captured in the data storage device 1 15. Since unnecessary files are not imported, the capacity of the data storage device 115 does not need to be increased more than necessary. The display process of the captured data is the same as described above.

Next, another embodiment in which the present invention is applied to a car navigation device will be described in detail. However, the present embodiment is not limited to a car navigation device, but can be applied to, for example, a personal computer or a portable information terminal having a current position detecting means.

First, FIG. 11 shows an example of a hardware configuration of a car navigation device according to the present embodiment. In FIG. 11, the same elements as those shown in FIG. 1 are denoted by the same reference numerals.

The car navigation device 100 includes a CPU 111 that controls the entire device by a program process, a current position detection unit 112 for detecting a current position, and a CPU 111. ROM 113 that stores the control program to be executed and necessary data, RAMI 14 that provides a work area, buffer area, and temporary storage area when the CPU 111 executes the program, and stores some data in a nonvolatile manner Data storage device (flash memory, etc.) 115, map information storage unit (here, CD-ROM) 116 that stores road map information, and display 1 1 that displays maps and the contents of HTML files described later 7, a speaker 118 for outputting audio information, an input device (eg, an operation key, a touch panel, a remote controller, etc.) for a user to input an instruction 119, and a data broadcast such as a television multiplex broadcast as an antenna. 12 It has a data broadcast receiving unit 121 that receives data via an external device 0, and a communication control unit 122 that controls data communication with the outside.

As described above, the communication control unit 122 is connected to, for example, a mobile phone or the like via the connector 123, and can access the Internet. Data broadcasting may use satellite broadcasting in addition to terrestrial broadcasting. In the present embodiment, as the current position detection unit 112, other means such as a known self-contained navigation may be used instead of or in addition to the force using the GPS receiver.

The configuration of data received by data broadcast receiving section 121 in the present embodiment is the same as that shown in FIG. 2 in the previous embodiment. That is, the transmission data is transmitted in the same file after transmitting a set of a plurality of data files 22 sequentially with the management file 21 at the top, transmitting the last data file 22 continuously, or after a predetermined time interval. Is sent and repeats this.

FIG. 12 shows a specific example of the management file 21 in the present embodiment. The management file 21 with the file name kanri. 丽 G describes the attribute information of the subsequent data file 22 (HTML file). In this example, for the sake of simplicity, the force shows only the HTML file as de one ^datafile?, It may also contains do the GIF files, and the like. If so, should the same number be assigned to the relevant data files, as in the management file shown in Figure 3? desirable.

In the example of Fig. 12, for each HTML file, its file name 211, classification name 212, transmission date and time 213, effective date and time (expiration date) 214, location information (East and North latitude) 215, region name 216 Is described. The classification name 212 indicates the information classification of the HTML file such as “convenience store”, “gasoline stand”, “fast food”, “news”, and the like. The transmission date and time 213 may be considered to be the same as the update date and time described above. The location information 215 is a location related to the HTML file. For example, in the case of an HTML file related to a fast food restaurant, the location information is a location of the restaurant. Some HTML files do not have location information, in which case specific numerical values or symbols (all 0s in this case) are described.

Like the management file in FIG. 3, the contents of the management file 21 shown in FIG. 12 are items 21 1 to 21 6 arranged in a row with a space therebetween. Since the number of items in a file is known, each item can be identified by the number of spaces after it. In this format, the amount of data in the management file 21 can be minimized.

FIG. 13 shows an example of a management file having the same contents as the management file 21 of FIG. 12 but having a different format. In this example, the identifiers 2 21 to 2 26 indicating whether the item is valid are added before each item 2 11 to 2 16 respectively. different.

FIG. 14 shows an example of an information selection menu screen for setting information selection conditions displayed on the display 117 in this embodiment. In this example, the distance between the current position of the user (vehicle) and a specific position specified in the HTML file, and the information classification are adopted as information selection conditions. These may be of a predetermined fixed value power?, It can preferably be user ^force? Variably set. In the example of Fig. 14, the user selects the range of the condition distance from multiple options (within 1 km, within 5 km, within 10 km, OFF). If it is "OFF" force ^s designation means that no matter the distance of conditions. Similarly, the user selects the desired information category (convenience store, gas station, fast food, etc.) as the information category.

In the example of FIG. 14, the user selects the radio button 51 (circular button) or the check box (square button) 52 corresponding to each condition by a single operation or a touch panel operation. The radio button 51 is used to select one item from a plurality of options. The check box 52 is for selecting an arbitrary number of items from a plurality of options, as described above. In the example of the figure, a black circle and a black square indicate the selected item. If cancel button 55 is specified while the condition item is selected, the entry is canceled and the registration status returns to the state before the entry. By instructing the register button 54, this condition is registered, and the screen returns to the original screen (not shown) which started this screen.

FIG. 15 shows another example of an information selection menu screen for setting information selection conditions. In this example, it is possible to set different distance conditions for each of the emotional categories. In the examples shown in Fig. 14 and Fig. 15, the user can input a desired numerical value in addition to or instead of the force to select from the numerical values given in advance as the magnitude of the distance. You may do so.

FIG. 16 shows a flowchart of an example of the data receiving process in the present embodiment. This process is executed in response to a user instruction or periodically. In the case of regular, it is preferable to allow the user to specify the interval. First, a management file is found from the received broadcast data and stored in the RAM 113 and the data storage device 115 (S701). Next, the loop variable n is set to 1 (S702), and the loop processing is started.

In the loop processing, first, the attribute information of the n-th HTML file (the group of items in one line in FIG. 12) is extracted (S703). Then, it is checked whether "distance" is specified as the information selection condition (S704). If not, the process proceeds to step S707, which will be described later. If there is, the current position of the user is confirmed by the current position detector 112 (S705). This step of determining the current position may be performed before the loop processing because the current position is not expected to change so much during the loop processing. Next, the distance between the two positions is calculated, and it is determined whether the distance is within the distance range specified by the force ^{s (} S706). The distance calculated here is a straight-line distance between the two positions for convenience. If it is out of the specified range, the process proceeds to step S713 described later.

If it is within the specified range, it is checked whether or not the information classification is specified (S707). If there is no designation, the process proceeds to step S709 described later, and if there is, it is checked whether the classification matches (S708). If they do not match, the flow proceeds to step S713 described later.

If the classifications match, it is checked whether a file having the same name as the HTML file has already been stored (S709). If not stored, the HTML file is fetched and stored in the data storage device 115 (S710). If it is not stored, it is checked whether the file needs to be updated (S711). Specifically, for example, the transmission date and time of the HTML file described in the management file and the transmission date and time of the stored file are compared, and if they are different, it is determined that updating is necessary. Alternatively, the effective date and time may be compared instead of the call date and time. If it is determined that the update is necessary, the same file in the data storage device 115 is updated (S712), and it is determined that the update is unnecessary. If so, the process proceeds to step S713. In step S713, the variable n is incremented (S713). Therefore, referring to the management file, it is confirmed whether or not there is a new n-th file (S714). If there is no such file, the process is terminated. If there is, the process returns to step S703 to execute the above process again. .

In this way, only HTML files having attributes that match the conditions specified by the user are imported into the data storage device 115. Unnecessary files are not imported, so that the capacity of the data storage device 115 does not need to be increased more than necessary.

When the information selection menu screen shown in FIG. 15 is used, it is preferable to execute the information classification judgment (S707 to S708) before the distance judgment (S704 to S706) in FIG. .

FIG. 17 shows a flowchart of an example of the display processing in the present embodiment. This process is started according to a user's instruction. At this time, each time the display processing is started, the menu screen of FIG. 14 or FIG. 15 may be displayed prior to the display processing. In the display processing of FIG. 17, first, the loop variable n is set to 1 (S801), and the following loop processing is started.

In the loop processing, first, the management file stored in the data storage device 115 is read, and the attribute information of the n-th HTML file in the management file is read (S802). It is checked whether the HTML file exists in the data storage device 115 (S803). If the file does not exist, the process proceeds to step S806, and if it does exist, it is checked whether the expiration date of the file has passed (S804). If it has not elapsed, the process proceeds to step S806, and if it has elapsed, the file is deleted (erased) from the data storage device 115 (S805).

Next, it is checked whether "distance" is designated as the information selection condition (S806). If not, the process proceeds to step S809, and if there is, the current position is confirmed (S807). With respect to this current position, it is checked whether the position described for the HTML file is within the range specified by the user (S808). If not, go to step S812.

If it is within the specified range, check if the information condition is specified as a selection condition. Bell (S809). If not, the process proceeds to step S811. If yes, it is checked whether the HTML file conforms to the classifying power s designated classification (S810). If they do not match, the process proceeds to step S812, and if they match, the corresponding part of the position of the HTML file is displayed on a map (S811).

Thereafter, the variable n is incremented (S812). If there is a new n-th file (S813), the process returns to step S802, and the above processing is executed again. If the new n-th file does not exist, an HTML file display instruction is received from the user (S814), and the contents of the HTML file are displayed on the screen instead of a map (S815). ). This display may be performed in a window opened on the map. If there is a termination instruction (S816), this processing is terminated.

If the user instructs (for example, another) HTML file display after the “return to map display” button 104 as shown in FIG. 19 described later (S81), the step is performed again. In step S815, the contents of the file are displayed in place of a map.

Note that when the file fetched according to the selection conditions in the reception process in Fig. 16 is displayed in the display process in Fig. 17, the selection conditions are checked again.First, when the file is fetched, Second, the selection conditions may have changed between the time the file was imported and the time it was displayed.

By the processing of Fig. 17, for example, as shown in Fig. 18, the user can draw the user's attention to the corresponding locations 92 and 93 on the map of the HTML file that match the selection conditions (for example, blinking dots). Display. When the user designates one of the places 92 and 93, the contents of the HTML file corresponding to the designated place are decrypted, and a display image is constructed and displayed as shown in FIG. This allows the user to find a destination within a specified distance from his / her current location and check its contents. The reference numeral 91 in FIG. 18 indicates the current position of the user. The screen in Figure 19 is an HTML file display screen, so the hot spots (or anchor points) 101, 102, 103, etc. set there are indicated. 1

By doing so, it is possible to access the Internet WEB site via the communication control unit 122 and a mobile phone or the like.

For HTML files with no location description (all 0s), the distance is determined to be unsatisfactory in the distance determination.

Data force of the object to be viewing user force ^s by this process? Because it is narrowed down, the user can quickly obtain necessary information.

Although only one distance is specified as the selection condition at a time, a plurality of distances may be specified. In that case, if there is something that matches the minimum distance, only that one may be imported, otherwise, the one that matches the next larger distance may be imported.

A third embodiment of the present invention will be described with reference to FIGS. The hardware configuration for realizing this embodiment can use the one shown in FIG. In the second embodiment, the distance and the information classification are used as the information selection conditions. However, in the present embodiment, the user attribute (sex, age) and the genre of information are further used. For this purpose, items such as gender, age range, and genre as user attributes are added to the management file described in FIGS. 12 and 12. For example, it specifies the gender and age range of the audience targeted for a specific HTML file, and specifies the genre of the information.

FIG. 20 shows a selection condition setting screen according to the third embodiment. This screen has input fields for the user's name, age, and gender, and input fields for an information selection menu. The information selection menu contains the same “distance” and “information classification” as in the second embodiment, as well as whether to perform a gender condition comparison, ON, OFF, or age condition comparison. Radio buttons for selecting ON, OFF, and genre (here, “all”, “news”, “traffic information”, “weather information”, “music”, “shopping”, “food”, etc.) are arranged.

FIG. 21 is a flowchart showing an example of a data receiving process for selecting information using the registration information. The same steps as those in the flowchart of FIG. 16 are denoted by the same reference numerals. Therefore, only the steps different from the flowchart of FIG. 16 will be described.

In the present embodiment, between steps S708 and S709, steps S1 21 to S1 2 4 force inserted. In step S121, it is checked whether a user attribute is specified. That is, it is checked whether gender or age in the information selection menu in FIG. 20 is set to ON. In the following step S122, if the gender is ON, the registered user's gender (male in the example of Fig. 20) matches the gender attribute specification (if any) of the HTML file. Find out what to do. If the age is ON, the age of the registered user (39 years in the example of Fig. 20) matches the age attribute (range of age) of the HTML file (if any). Find out what to do. If both gender and age are ON, check if both match. If they match, the process proceeds to the next step S123, and if they do not match, the process proceeds to step S713.

In step S123, it is checked whether a genre is specified. That is, it is checked whether any of a plurality of items of the genre is designated in FIG. If specified, it is checked whether or not the genre matches the genre of the HTML file (S124), and if they match, the process proceeds to step S709. If not, proceed to step S 7 13.

The processing after step S709 is the same as the processing in FIG.

FIG. 22 shows a flowchart of an example of the display process in the third embodiment. The same steps as those in the flowchart in FIG. 17 are denoted by the same reference numerals. Therefore, only the steps different from the flowchart of FIG. 17 will be described.

In this embodiment, during step S 8 1 0 and S 8 1 1, is inserted Step S 1 3 1~ S 1 3 4 force ^s. These steps S131 to S134 are substantially the same as steps S121 to S124 in FIG.

According to the third embodiment, the user attribute and the information genre are selected as the selection conditions on the assumption that the attribute information on the user attribute and the information genre is described in the management file as the attribute information of the HTML file. This makes it possible to acquire and display information under more detailed conditions.

Further, the feature of the information selection by the user attribute in the third embodiment can be applied to the first embodiment.

The preferred embodiment of the present invention has been described above. However, it is possible to make various modifications and changes without departing from the gist of the present invention. It is possible. For example, the acquisition and display of information Although the same condition is used as the selection condition, different conditions may be set for both of them using different selection menus. In this case, as a specific setting method, it is necessary to make the acquisition condition wider than the display condition, and to make a setting contrary to this, it is necessary to issue a warning to the user. s preferred.

Further, the data size may be added to the condition for selecting a data file.

Only the current position detected by the current position detector is used as the current position.However, by using the position input by the user as the current position, information on the periphery of a position different from the actual current position is acquired and displayed. May be made.

At present, the PHS (Personal Handyphone System) is used in combination with a portable information terminal that does not receive data while moving, or that has difficulty in normal communication while moving a vehicle. Available. In this case, since the current position can be determined with a certain degree of accuracy from the base station information of the PHS, this can be used as the current position information.

ADVANTAGE OF THE INVENTION According to the data broadcast receiving display method and apparatus of this invention, the information which a user needs among various miscellaneous information broadcast can be automatically selected. Therefore, the operability of the device is improved.

Further, the required capacity of the storage means for storing the broadcast data can be reduced, and the cost of the apparatus can be reduced. Industrial applicability
