Description

  According to the present invention, a digital data broadcast signal from a satellite and a terrestrial transmission station is received by a reception processing device, and a weather forecast and other region-specific information for different dates and times in a region preset by a user can be arbitrarily acquired and displayed. This is a regional information reception system that can be used.

Satellite digital broadcasting (ISDB-S) is a uniform broadcasting nationwide, and data broadcasting is also described in BML and transmitted by a data carousel.
For example, weather information systems such as AMeDAS provide weather information divided into regions by mesh division (for example, 20 km mesh).
Therefore, the weather forecast is broadcast as an additional data broadcast, and a binary table is constructed and broadcasted by weather information corresponding to the above-mentioned regional allocation and a zip code corresponding to the regional allocation.
In the reception processing apparatus, the postal code of the place of residence is recorded (registered) in advance in the memory (NVRAM) by the user using input means such as a remote controller.
The reception processing device extracts weather information corresponding to the registered zip code from the carousel-transmitted data, and externally displays the weather forecast of the user's residence on the screen.
However, since the satellite digital broadcast reception processing device is fixedly installed indoors, it cannot be used when the user goes out, and to view the weather forecast in any area other than the place of residence Therefore, it is necessary to re-register the postal code of the area in the memory, which requires laborious work.
On the other hand, terrestrial digital broadcasting (ISDB-T) is started, and a portable terminal having a portable reception function can be used together with a reception processing device for fixed reception.
Even in this case, since the regional information based on the regional information such as the residence set in the memory by the user is displayed, the regional information on the preset residential location even when the user moves to another region. Can only get.
This point has the same problem in mobile digital broadcasting.

As another method, a mobile terminal (i-mode (registered trademark), PDA, etc.) using a computer network can obtain regional information based on location information input by the user. There is a problem that it costs money due to the use of the line, and it is necessary to input the position information correctly each time, which is troublesome.
Therefore, in the provided information receiving apparatus disclosed in Japanese Patent Laid-Open No. 2003-143642, a GPS apparatus is used as the provided information receiving apparatus that moves with the user, receives a data broadcast from a broadcasting satellite, and displays the data on a display. There is also known a configuration in which information is acquired, an area in the traveling direction is predicted from the trajectory, information of data broadcasting in the area is selected and prefetched and accumulated.

Japanese Patent Laid-Open No. 2003-143642 See FIG.

In this invention, the user can obtain the information by region only by receiving the digital data broadcast. Unlike the acquisition of information via the interface, the user can obtain the necessary information by region without incurring communication costs during mobile. It is to provide a system capable of receiving.

Note that one or a plurality of dates and times specified in the present invention may specify only days, but in the case of time, they include different times on the same day, same times on different days, or different times on different days.
The plurality of regions refers to regions corresponding to the designated date and time, and widely includes all the same regions, all different regions, or a combination of a plurality of the same regions and different regions.
In addition, in the present invention, the moving body may be a person other than transportation means such as an automobile, a ship, and an airplane, and may be anything as long as it can move the reception processing device.

In the area-specific information receiving system of the present invention, the user records a condition setting file including data broadcast, date, and area in the reception processing device, so that the user can set the predetermined date and time from the broadcast wave of digital data. Since any specified area-specific information can be obtained, the area-specific information can be viewed without being confined to the place of residence.
In particular, when a user moves between a plurality of regions, the date and region can be specified in the condition setting file. Therefore, the region-specific information corresponding to each date and region can be stored in advance using a reception processing device. Can be displayed.
These can be realized by a simple configuration in which the condition setting file is stored in the memory, and the user can easily and inexpensively obtain desired regional information.
In addition, service providers such as broadcasting stations can provide regional information required by users as national broadcasts without the need to install special servers.
And even if it is limited information for each region, it can be specified by different combinations of date / time and region, so that the combination pattern can be used as much as the specification of date / time and region increases.

  A preferred embodiment in which the present invention is applied to an area-specific information reception system using terrestrial digital broadcasting will be described below with reference to the drawings.

FIG. 3 is a schematic explanatory diagram illustrating the regional information reception system according to the first embodiment.
Reference numeral 1 denotes a broadcasting station that performs terrestrial digital data broadcasting (ISDB-T), and 2 denotes a reception processing device (STB) such as a terrestrial digital tuner serving as a user platform.
As shown in FIG. 1, the reception processing device 2 includes a receiving unit 2A, a memory 3, and a processing unit 2B that performs arithmetic processing on data.
In the illustrated example, the reception processing device 2 for fixed reception connected integrally with the display D is shown, but a portable terminal with a portable reception processing function described later may be used.

As an example of data broadcasting by region, a case where weather forecast information is used will be described.
As described above, the broadcast station 1 is provided with a spot number obtained by dividing the local forecast area into a mesh (for example, 20 km mesh) from the weather information system such as AMeDAS and weather information for each spot number. And a binary table associating the weather information for each location number and the user's regional information corresponding to the location number as content, and broadcasting by carousel transmission together with other data, which is received by the receiving unit 2A To do.
The type of weather information provided here may be weather information for each region, and the type and content of the weather information are not particularly limited.

When the user's regional information is, for example, a zip code, a group of zip codes included in the spot number is set in advance based on the spot number, and is associated with weather information corresponding to the spot number.
Alternatively, the content is created by associating the point number including the zip code with the weather information corresponding to the point number based on the zip code.

As a result, if a zip code is registered as the user's area information in the memory 3 of the user's reception processing device 2, the processing unit (controller) 2B of the reception processing device 2 uses the zip code as a keyword, The weather information of the point number corresponding to the postal code can be extracted from the broadcast wave of the digital data and can be externally displayed on the display D.
When the area code is registered as the user's area information in the memory 3 of the reception processing device 2, the area code is used as a keyword instead of the zip code and corresponds to the area code from the broadcast wave of the terrestrial digital data. The weather information of the point number can be extracted and externally displayed on the display D.

The user's regional information is input means such as a remote control in which a postal code or a regional code is set as a viewer residence region setting in a portion (not shown) of the NVRAM operator (broadcasting station) common memory incorporated in the reception processing device 2 Is recorded (registered) by using the processing unit 2B of the reception processing device 2 and is read out.
Further, the NVRAM as the memory 3 of the reception processing device 2 is also provided with a memory dedicated for each business operator (broadcast station or the like).

  Therefore, in this embodiment, the channel or data broadcast (ES data or module) for acquiring the regional information such as the weather forecast is specified in the dedicated memory portion allocated to each business operator (broadcast station, etc.) One or more date / time and region are designated and input by the remote controller 4 or the like, and these data are stored in the memory as a condition setting file f (BTB file as an example).

Here, the date and time specified in the condition setting file f is not limited to the case where the dates are different as described above, but may be the case where only the time is different on the same day.
The area information may be any area as long as it can specify the area, such as the zip code or area code. For example, the area name may be directly input and converted into an area code. Alternatively, a system that can search the place name as a keyword as it is may be used.

Then, the processing unit 2B calls the condition setting file f, and designates the designated date and time in the data broadcasting of the designated channel from the broadcast wave received by the receiving unit 2A, and the designated region corresponding thereto. Information by region such as weather forecast can be acquired and displayed on the display.
In the above-described embodiment, the memory portion allocated to the reception processor 2 dedicated to the NVRAM operator is used as the memory 3, but the condition setting file f is stored in the operator common memory. It is good also as a structure which acquires information according to area based on it.

  Further, in the present invention, the memory 3 is not limited to the above NVRAM. For example, a portable memory such as a hard disk incorporated in or attached to the reception processing device 2 or a removable memory card may be used. The means may be set so as to call the condition setting file f stored therein and acquire data broadcasting area-specific information.

  By storing the condition setting file f in the memory 3 of the reception processing device 2 in this way, when the receiving unit 2A receives the terrestrial digital data broadcast, the control unit 2B calls the condition setting file f, The weather information in the designated area at the designated date and time in the data broadcasting of the channel designated in the condition setting file f is extracted from the data transmitted in the carousel and displayed externally on the display D.

Thereby, in the case of the reception processing apparatus 2 for fixed reception, the user can acquire information for each region such as a weather forecast for an arbitrary region while using the reception processing device 2 while in the residence.
Although not shown, a mobile terminal with a reception processing function for mobile reception described later may be used in place of the reception processing device 2.
In that case, when the user moves between the regions with the portable terminal, the information for each region can be acquired in accordance with the movement to the region.

FIG. 4 is a schematic explanatory diagram illustrating an area-specific information reception system according to the second embodiment in which a user uses a plurality of reception processing apparatuses.
Reference numeral 1 is a broadcasting station that performs digital terrestrial data broadcasting, 2 is a first reception processing device (STB) such as a terrestrial digital tuner, and in the illustrated example, a reception processing device for fixed reception, and 6 is a first reception processing device. This is a second reception processing device different from the first reception processing device 2, and in the illustrated example, a portable terminal 5 with a reception processing function for portable reception.

  Examples of the portable terminal 5 include portable or wearable terminals such as portable television receivers, portable personal computers (notebook computers, PDAs, etc.), portable telephones, car navigation devices, and the like that have a portable reception function for terrestrial digital data broadcasting. Say.

In this embodiment, the combination of the reception processing device 2 for fixed reception as a platform and the portable terminal 5 as the reception processing device 6 for portable reception is illustrated as a plurality of reception processing devices. The present invention is not limited to this, and all may be fixed reception processing devices, or all may be reception processing devices (portable terminals) for mobile reception.
Further, the number of reception processing devices is not limited to two, and three or more may be used.

As in the first embodiment, the user uses the input means such as the remote controller 4 to specify the data broadcast or channel for acquiring the weather forecast or other region-specific information, and to acquire data from the data broadcast 1 or A plurality of dates and times are input and stored as a condition setting file f in the memory 3 of the first reception processing device 2.
In this embodiment, since a plurality of reception processing devices 2 and 6 can be used, especially when the user moves geographically (moves between different regions), information by region corresponding to each region is acquired. be able to.

Here, the date and time specified in the condition setting file f may include the case where the date is different, and the case where only the time is different on the same day.
In addition, the date and time is not limited to the date and time when the vehicle actually passes through the region, and is set so that information for each region can be acquired from the day before arrival at the destination or several hours before arrival. This is preferable because the state of the destination can be known in advance.
Moreover, you may enable it to acquire the information according to area after passing.

Next, the condition setting file f is transferred from the memory 3 of the first reception processing device 2 to the memory 7 of the second reception processing device 6 using the data transfer means 10 (two points in FIG. 1). (See the chain line).
As this data transfer means 10, a known method can be used.
For example, (1) a method for reading a condition setting file f recorded on a portable medium such as a memory card into the memory 7 of the second reception processing device 6, and (2) a second reception from the first reception processing device 2. A method in which the processing device 6 uses a mail function to read a condition setting file into the memory of the portable terminal, and (3) data transfer using a radio signal such as data transfer using infrared rays or data transfer using Bluetooth (registered trademark). And (4) a method of transferring a condition setting file f by connecting a data transfer cable between the first reception processing device 2 and the second reception processing device 6.

Thus, by transferring the condition setting file f to the memory 7 of the second reception processing device 6, when the second reception processing device 6 receives the terrestrial digital data broadcast, It is possible to easily obtain regional information such as weather forecast in a predetermined region at the date and time set in the condition setting file f from digital terrestrial data broadcasting without special setting.
That is, even if the user moves from region A to a different region B or region C, and the mobile terminal 5 moves accordingly, the second reception processing device 6 uses the second reception processing device 6 for each region such as a weather forecast in region B or region C. Information can be obtained from terrestrial digital data broadcasting.

  FIG. 5 shows an example of the data receiving unit according to the second embodiment. As an example of the data transfer unit, the user carries the portable memory 15 storing the condition setting file f and attaches it to the desired reception processing device 2 or 6. FIG. 6 is a schematic diagram for explaining the third embodiment in which the same condition setting file f can be used everywhere, and FIG. 6 is a block diagram thereof.

In the third embodiment, both the first reception processing device 2 and the second reception processing device 6 have a configuration in which a portable memory 15 such as a memory card can be detachably attached.
In the first reception processing device 2, the control unit copies the condition setting file f stored in the memory 3 to the portable memory 15 in accordance with an instruction from an input unit such as the remote controller 4. Alternatively, when the portable memory 15 is used directly as the memory 3, the portable memory 15 is used as it is.

Then, the portable memory 15 in which the condition setting file f is recorded is detached from the first reception processing device 2 and attached to the second reception processing device 6.
The second reception processing device 6 copies the setting file f to its own memory 7. Alternatively, the portable memory 15 may be handled as its own memory 7.

In this way, the user can use the condition setting file f in any second reception processing device 6 simply by carrying the portable memory 15.
Therefore, the second reception processing device 6 is not limited to the portable reception reception processing device provided in the portable terminal 5 as shown in the figure, and may be any fixed reception processing device.
Other configurations are the same as those in the above embodiment, and the description thereof is omitted.

As a result, the condition setting file f composed of the data recorded on the portable memory 15 such as the channel or data broadcast, the date and time, and the region is carried by the user as the portable memory 15 or the portable terminal 6. Attached to and carried.
Then, by attaching the portable memory 15 to the separate second reception processing device 6, the date and time based on the condition setting file f from the terrestrial digital data broadcast is controlled by the control means of the second reception processing device 6. Since the regional information such as the weather forecast in the region A at the date and time b, the region B at the date and time b, and the weather forecast in the region C at the date and time c is acquired, the information by region for each moving region is moved when the user moves between the regions. It can be displayed on the display D according to the scheduled date and time.

  In the above-described embodiment, the case where the user has both the reception processing device for fixed reception and the portable terminal having the reception processing device for portable reception has been described as an example. When the terrestrial digital data broadcast can be received only by the terminal, the condition setting file data can be directly input to the memory of the mobile reception function.

In the first to third embodiments, weather information (weather forecast) has been described as an example of the region-specific information. However, the present invention can be widely applied to terrestrial digital data broadcasting in which different information is broadcast for each region. Can do.
For example, the region-specific information may be the operation status of transportation facilities such as trains and airplanes, road traffic congestion information, and other events and other various types of information that are provided for each region.

  In the present invention, the method of inputting the date and area of the condition setting file f is not limited to the method of manually inputting all the date and area individually using the input means 4 such as a remote controller. It is also possible to use a method of automatically inputting the passage date and passage area of the intermediate point using a search algorithm using a certain algorithm.

  For example, a well-known route setting means is installed in the reception processing device by a car navigation system, a known route search program of a personal computer, or a route search program (for example, “Station Spat” (registered trademark) or “Transfer information” (trademark)). Aside from that, the user only needs to enter at least two points: the departure point (and departure time if necessary) and the arrival point (and arrival time if necessary). Using the program that implements the output algorithm, the date and area of the passing point are determined (if multiple routes are shown, select one of them), and the input departure and arrival date and time In addition to the point and the area (region), the passage date and time of the intermediate point and the data of the passage point (area) may be automatically input to create the condition setting file f (the dotted line portion in FIGS. 1 and 2). reference)

  In this case, the route setting means equivalent to the first reception processing device 2 is also mounted in the second reception processing device 6 or equivalent to the first reception processing device 2 and the second reception processing device 6. A setting application having the path setting function may be realized by distributing data broadcasting or the like.

FIG. 6 is a development of the first embodiment, and a case where the reception processing device 2 is built in or connected to the car navigation device 20 will be described.
In this case, similarly to the first embodiment, the reception processing device 2 built in or connected to the car navigation device 20 stores a plurality of areas scheduled to move in the order of arrival time and stores them in the memory as the condition setting file f.
The plurality of area information is obtained by inputting a destination by a known route search function or VICS function (shown as an example of route setting means) provided in the car navigation device 20, and the main passing points and destinations. Each of the estimated arrival date and time and area data can be input to the condition setting file f of the reception processing device 2 by using a conversion table.

Thus, regional information such as a weather forecast corresponding to the date and time and the regional data is acquired from the terrestrial digital data broadcast, and the passing point region and destination are displayed on the monitor of the car navigation device 20 to which the reception processing device 2 is connected. It is possible to display area information at each estimated arrival time in each area. An example of this screen display is shown in FIG.
In addition, since the arrival time of the relay point and the destination can be corrected by using the GPS function 21 of the car navigation device 20, the date and time data corresponding to a predetermined area stored in the condition setting file f is also included. It is preferable that the information can be changed at any time in conjunction with this, so that the regional information can be changed accordingly (see the one-dot chain lines in FIGS. 1 and 2).

The GPS function 21 is not limited to the above-described embodiment, and may be one built in the reception processing device 2, one that connects an independent GPS device, or one that uses a GPS function provided in a mobile phone or the like. .
In the embodiment, the regional data is not limited to data corresponding to the administrative division, but may be information specifying an interchange on a highway.

  In the above embodiment, the case has been described in which the data obtained from the route search function of the car navigation device 20 or the GPS function 21 can be taken into the reception processing device 2, but the data acquired by the reception processing device 2 is reversed. The car navigation device 20 may capture and process the image, and may be externally displayed on the monitor in combination with the car navigation image.

As described above, in the present invention, the date and time and area data constituting the condition setting file f are automatically determined using a manual or a fixed algorithm, or are input by combining a manual part and an algorithm part. May be.
Further, the region-specific information acquired from the terrestrial digital data broadcast is not limited to one type, but a plurality of different types, for example, weather forecast and traffic jam information, or local entertainment information, etc. are used using the search condition file f. You may enable it to display externally simultaneously.

In each of the above embodiments, the region-specific information for the specified date and region is acquired based on the date and region data, but the specified date and time is not short, in other words, the date and time are not specified. It is good also as a structure which acquires the information according to area on the condition of only a specific area.
In addition, it goes without saying that various design changes can be made without departing from the scope of the present invention.

This regional information reception system is not limited to the case where a single user uses it.For example, when traveling in a group such as traveling in a group, all the mobile users can read the same condition setting data so that all the Can be acquired and can be used as a schedule (see FIG. 8).
It can also be used as a schedule book with a weather forecast (information by region) when the region is different, such as a meeting place (see FIG. 9).
