ADVANTAGE OF THE INVENTION According to this invention, the portable terminal which can obtain information simply can be provided.

  Hereinafter, embodiments of an information transmission system, a terminal device, and an information selection method according to the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram showing the overall configuration of the information transmission system according to this embodiment. Broadcast information 1010 transmitted from the broadcasting station 1000 that transmits information is information transmitted to one-way / unspecified majority parties using an FM broadcast audio multiplex channel or the like. The mobile terminal 1200 owned by the user 1300 has the city map information 1100 input in advance using an IC card or the like, and can display a city map on the display. The portable terminal 1200 can receive broadcast information 1010 broadcast by the broadcast station 1000, and normal audio broadcasting can be listened to by the user 1300 using the headphones 1500. Here, the broadcast information 1010 contains information about the city, such as merchandise sold at the store, restaurant information, and the like. The mobile terminal 1200 receives the broadcast information 1010 and receives it. Information desired by the user 1300 is selected from the information, and operations such as generating the information and informing the user of the information are performed. As an example of the operation, a mobile phone 1400 connected to the mobile terminal 1200 is used to call the information source and directly obtain the latest information, or perform operations such as purchase and meal reservation. I can do it.

  FIG. 2 is a block diagram showing a flow of information inside the portable terminal used in the information transmission system according to the present embodiment. The broadcast information in FIG. 1 is received by the mobile terminal, and then necessary demodulation is performed, and is input as transmission information 2101 into the mobile terminal. The transmission information includes various types of information as described with reference to FIG. 1, and type information representing the type of information is included in the information. This is decoded by the type information reading 2100, and a type control instruction 2102 for instructing an operation according to the type of information is transmitted. The transmission information 2101 is input to the filter 2000 after the type information is read. The filter 2000 further divides the transmission information according to the instruction of the type control instruction 2102. Specifically, the information is selected so that unnecessary information is not provided to the user by storing the information stored in the storage device 2300 and allowing the viewer 2200 to pass information to be displayed and discarding other information. . The filter 2000 gives an instruction for designating information to be displayed as information to be displayed by the viewer 2200 to the viewer 2200 as a type control instruction 2103. Information required by the user stored in the storage device 2300 is sent to the viewer 2200. In response to the type control instruction 2103 given from the filter 2000, the viewer 2200 outputs information to be displayed as display information 2201. In addition, there are instructions from a timer and a request switch from the user (not shown), information is immediately displayed to the user according to the type control instruction 2102, displayed after a certain period of time, or the user reads the information. When the request is made, it is displayed for the first time. In addition, a display 2001 that does not require storage such as a time signal is sent directly to the viewer 2200 without going through the storage device 2300, and in this case, it is provided as display information 2201 to the immediate user. The type information reading 2100, the filter 2000, and the viewer 2200 in this block diagram can be realized by executing a program (not shown) stored in a memory, which will be described later with reference to FIG.

  FIG. 3 shows an example of the content of information transmitted by the information transmission system according to this embodiment. Transfer data 3000 represents one record in transmission information 2101 in FIG. The contents of the example of the transfer data 3000 according to the present embodiment are composed of a header 3010, a data type 3020, a data attribute 3030, a data length 3040, a data body 3050, and a parity 3060. The header 3010 is a unique code that does not exist in other items constituting the transfer data 3000, and the receiving side can reliably confirm the position of the header. The data type following the header 3010 represents the type of transfer data. As the type information, for example, as shown in 3021, classification is performed for information on roads and shops such as emergency information, road information, and men's clothing, and also on types of specific products. Using this classification, the filter described in FIG. 2 operates, and the user selects necessary information. A data attribute 3030 indicates the attribute of the data body in the transfer data 3000. The attribute information indicates the contents of the data body as shown in, for example, 3031. When the data body is in a text format, an image is attached, or a procedure manual such as a restaurant reservation procedure described later is attached. This is the case. Subsequently, in order to check whether or not the transfer data 3000 has been received reliably following the data length 3040 indicating the length of the data body, which is the body of the transfer data 3000, and the data body 3050, the data type A parity 3060 indicating the sum of the character codes up to the main body is added, and one record of the transfer data 3000 is completed. Here, the transfer data 3000 according to the present embodiment has a variable length because the data body 3050 has a variable length. Here, if the length of the transfer data 3000 is a fixed length and the same record is repeatedly transmitted multiple times, even if the receiving side starts receiving from the data attribute in the middle of the transfer data 3000, for example, one record from there. Receiving data by dividing it into lengths, sorting the data by detecting the header 3010, and receiving one record even if it is received from the middle of a record instead of receiving from the header It can be completed only by receiving the message.

  An example of the contents of the data body 3050 is shown in the data body information 3051. The icon design of the store to be displayed on the map, the text header indicating the head of the text, the text body describing the store guide, the image header indicating the head of the image data and the length of the image data if an image exists, It is a procedure header and procedure data indicating the image data main body and the head of the procedure data. Here, the procedure data will be explained with reference to FIG. 7. Basically, the function call for displaying the window having the designated message is called, and the next procedure to be performed when the designated button is pressed in the window is shown. When a phone is connected to the setting and portable terminal, it has a function call such as automatically calling and accessing the host. Each function is stored as a library by the mobile terminal itself, and they operate according to the hardware and software of each mobile terminal, but the calling method is unified and the procedure data received by any mobile terminal is executed. It is configured as possible.

  FIG. 4 is a block diagram illustrating a hardware configuration of the mobile terminal according to the present embodiment. Around the bus 4050, the memory 4010, the display 4020, the touch panel I / F 4030, the IC card I / F 4040, the radio 4071, the reception signal demodulation circuit 4070, the communication means 4081 such as a telephone, and the modulation / demodulation circuit 4080 around the bus 4050. A headphone 4091 for listening to the received broadcast, a voice output means 4090, a voice synthesis circuit 4092 for interrupting the message to the voice and providing it to the user are installed.

  The memory 4010 stores filter information 4011 described later with reference to FIG. 5, acquired information 4012 selected using the filter information, and the like. The display 4020 displays a map, information about shops, etc. to the user. In this embodiment, the input from the user to the terminal device uses a touch panel integrated with the display, and includes a touch panel I / F 4030 for that purpose. It is sufficient that the same operation can be performed with a keyboard, a mouse or the like as in a normal personal computer. The IC card I / F is used to input the map information described with reference to FIG.

  Broadcast information input to the terminal is detected by a radio 4071 and converted into a digital signal by a demodulation circuit 4070. In the present embodiment, in response to the case where the audio broadcast is also sent digitally, the digital signal is returned to the audio signal using the audio output means 4090 and listened by the headphones 4091. This is detected by the radio 4071. The recorded signal may be heard directly by the headphones 4091 through an amplifier or the like (not shown). The digital signal demodulated by the demodulation circuit 4070 is collated with the filter information in the memory 4010, and only necessary information is selected and stored in the acquired information 4012 or displayed on the display 4020. Further, in the case of information that requires urgent information, not only the display on the display 4020 but also the voice synthesizing circuit 4092 can be used to play a sound such as an alarm or a message on the headphones that the user is listening to. Further, when the user wants to contact the information source or the like according to the obtained information, the user can communicate with the communication means 4081 such as a mobile phone or a public telephone via the modulation / demodulation circuit.

  FIG. 5 is an explanatory diagram showing the structure and operation of the filter of the portable terminal according to the present embodiment. The filters are described in the filter table 5000 in the order of priority. The emergency information used for the disaster report etc. is always described in the 0th, and this is a structure that cannot move in other order. From the first, the keywords desired by the user are arranged in order. In this case, since the user wants to shop in the order of hats and umbrellas in the city, he places importance on information about hats and umbrellas. In the following, along with road information indicating dead end road information due to road construction, etc., bazaar, and shoes information. All the information described in the filter table is stored in the memory in FIG. There is an event threshold 5010 that indicates a particular location in the filter table 5000. The event threshold is activated not only by storing information in the memory but also by notifying the occurrence (event) of the user's information when information having a priority higher than the threshold is received. This is a threshold value indicating that. In this example, the event threshold value 5010 is set under the first hat, and when information about the hat is generated, an event notification window 5030 is opened on the terminal display screen 5020, and information about the hat is displayed to the user. The information about the store that was received is transmitted. The event threshold value 5010 has a structure that cannot be set above the 0th emergency information, and the occurrence of emergency information is always transmitted to the user. The type information described in the filter table 5000 can be directly input by the user, or the current position of the mobile terminal can be automatically input as a keyword from a device that detects a location such as GPS (Gloval Positioning System). . As a result, it is possible to follow the procedure of receiving emergency information, which will be described later, with priority given to emergency situations in the vicinity of the terminal. The type setting may be specified in the form of logical operation results of a plurality of keywords, for example, (umbrella) AND (weather = rain). Here, a logical operation may be performed by automatically using keywords such as personal information, sex, hobbies, and age of the user possessed by the mobile terminal.

  FIG. 6 is an explanatory diagram showing a function of cooperation with the map of the event notification window described in FIG. On the terminal display screen 6000, as in FIG. 5, an event notification window 6010 is opened to notify the user that information related to the hat has occurred, thereby notifying the user of the occurrence of the event. Here, the map button in the window is touched to switch to the terminal display screen 6020, and the location of the store notified in the event notification window 6010 is displayed on the map. In this case, the coordinates of the shop are put in the data body in FIG. 3, and the portable terminal may display a graphic based on the icon design of the data body information in FIG. Here, in the display function of the mobile terminal, if the transferred icon cannot be displayed due to the limitation of the number of pixels or the number of colors, the terminal can decode the icon design independently or display the original icon of the terminal itself. It ’s fine.

  FIG. 7 is an explanatory diagram showing an embodiment in which the procedure manual on the broadcast information described in FIG. 3 is actually used. In this embodiment, it is assumed that the user wants to find a restaurant and make a reservation. On the terminal display screen 7000, the user knows that there is a desired restaurant using the event notification window 6010. Here, for example, if the user is not interested in the restaurant, the subsequent procedure can be canceled by tapping a portion other than the event notification window 7010, for example. If you are interested in this restaurant, touch the reservation button to move to the terminal display screen 7020 and display a map showing the location of the restaurant as shown in FIG. When the reservation button is further pressed, a reservation menu 7030 is displayed, and a detailed reservation can be made. In the reservation menu 7030, it is possible to make an order from the menu list shown by setting the date, time, number of people to eat. After setting these settings in the editor format, the reservation menu 7040 is displayed by touching the reservation button, and the reservation content is confirmed. If the user wants to cancel the reservation, touch the cancel button, and if he wants to make a reservation, touch the completion button to complete the reservation procedure. These procedures and menu screens are described in the procedure data in the data main body information 3051 in FIG. Although not shown here, even if the reservation procedure is canceled once, the data including the reservation procedure is stored in the memory of the mobile terminal, so for example, a list of information stored in the memory (not shown) is displayed. By selecting, it is possible to call this reservation procedure later and make a reservation again. In this operation, when the user touches the reservation button, the telephone connected to the portable terminal is used to connect to the restaurant itself or the information management computer commissioned by the restaurant, and exchange the reservation. . In addition, even when the phone is not directly connected to the mobile terminal, the reservation method is displayed on the display, so that the user can talk directly with the store using a nearby public phone while looking at the display on the mobile terminal. You can make a reservation.

  Another example of the execution of the procedure included in the broadcast information is the function of selecting broadcast reception in FIG. When broadcast information is transmitted by FM broadcast character multiplex channel and the receiving mobile terminal has a function of receiving FM audio broadcast, the broadcast information transmits FM audio broadcast program information, and the user receives the program information. You can check on the mobile terminal display, select the station you want to listen to and listen. In addition, if a general genre (rock, pop, etc.) is registered in advance, a cooperative operation is possible in which the tuner automatically switches to a station that plays music of that genre.

  In addition, restaurant reservations and product reservation purchases, etc., are automatically made when the conditions set by the user are met in advance, and automatic cooperation that informs the user that the reservation or purchase procedure has been completed separately. A system is also possible. In this case, if the amount exceeds a certain amount, the automatic procedure will not be performed even if other conditions are met, and cancellation or the user must be notified, and unless the user presses the OK button, the reservation or purchase procedure will be performed. Some ingenuity is required to avoid taking it.

  FIG. 8 is an explanatory diagram showing the operation of the mobile terminal when emergency information is received. The mobile terminal that has received the emergency information opens an emergency information display window 8030 on the terminal display screen 8010. When emergency information is received, as described in the explanation of FIG. 5, the user always sees the emergency information, and the emergency information display window 8030 is always displayed regardless of the setting of the user.

Here, it is informed that a fire has occurred at a nearby station, and touching the evacuation place display button 8040 makes a transition to the terminal display screen 8020 to display the evacuation place where the fire site, especially a rescue facility, etc. are installed. To do. Or, without touching the evacuation site display button, it is possible to switch to the map of the evacuation site simultaneously with the display of the emergency information display window 8030.

  FIG. 9 is an explanatory diagram illustrating an operation of the mobile terminal that receives the disaster victim information regarding the reception of the disaster information. The name of the person who wants to know safety is registered in the portable terminal in the same manner as the filter of FIG. When a large-scale disaster such as an earthquake or fire occurs, the name and status of the victims are still read out on television broadcasts and radio broadcasts. Receive that information. When disaster information is being broadcast, a message 9020 indicating that the disaster information is being monitored is displayed on the terminal display screen 9000 of the portable terminal. When the name of the person who wants to know the safety registered earlier is found in the broadcast disaster information, the portable terminal opens the injured person information display window 9040 on the terminal display screen 9010 and uses the safety information of the designated person. Inform the person. As for the name of the person who wants to know the safety to register here, all names of the address book already possessed by the mobile terminal or the name of the person with the designated mark in the address book may be automatically registered. . In addition, the location of the hospital where the victim was transported is displayed on a map, or when the emergency contact is necessary especially in the case of relatives, the hospital and the disaster You may have the structure which cooperates with the telephone contact with the contact information to a person.

  FIG. 10 is an explanatory diagram showing an embodiment in which the latest information on the map is transmitted using the information transmission system according to the present invention. In FIG. 10A, the map information 1100 previously input to the portable terminal 1200 is displayed on the terminal display screen 10000 as described in FIG. The format of this data is, for example, as shown in FIG. 10B, absolute coordinates 10300 expressed by absolute values on the earth such as latitude and longitude, display coordinates 10400 when displayed on a screen at a specific scale, and An attribute 10500 indicating a thickness of each road, a type for distinguishing between a national road and a general road, passage permission and the like described later, and the like is configured. Here, an attribute 10500 indicates an attribute related to a road starting from the corresponding coordinates. The map data possessed by the mobile terminal has these data for each scale, or the display coordinates and attributes are calculated for each scale, or each time the scale for displaying the display coordinates is changed, This is information input in advance to the mobile terminal, and is not the latest information at that time when the user is walking with the mobile terminal. Specifically, as shown in the terminal display screen 10100 in FIG. 10A, if one road is closed due to construction or the like for a certain period, it may not be reflected in this map data. There is. In the present embodiment, the latest map information is provided to the mobile terminal using broadcast information. Specifically, a line segment as shown in FIG. 10C and a new attribute are transmitted as a pair, and the mobile terminal that has received this information adds this information to the end of the map information data that it has and displays it. To do. Therefore, at this time, after the closed road is displayed in a state where it can be passed once, when the data at the end of the map information is read from the memory, the display indicating that the road is not allowed is displayed as in the terminal display screen 10100 of FIG. Is made. Then, the map information in the memory is sorted to incorporate the latest map information when the CPU is free, such as when the mobile terminal is powered off.

  FIG. 11 is an explanatory diagram showing a method for updating in advance information that a mobile terminal obtains in advance in general information including information on shops and restaurants and map information. The portable terminal used in the information transmission system according to the present embodiment can have map information and general store information in advance. In FIG. 11, information obtained in advance is received by the portable terminal 11020 directly from the host 11000 through the telephone line 11010 or by using a medium such as the IC card shown in FIG. The data is received once at 11040, stored in a hard disk drive (HDD) 11050 attached to the PC, and then sent to the portable terminal 11030. The format of the data is 11060, and the original version data such as all maps are entered starting with the version number of the data. A user who uses this service for the first time with a mobile terminal needs to obtain the original data at least once. The latest information thereafter can be obtained directly through the host 11000 and the telephone line 11010 in addition to the method of obtaining using broadcast information as shown in FIG. Both receive the difference data 11070, so that the latest information can be obtained with a small amount of communication. The obtained difference data 11070 is added to the original data 11060 and used as the upgrade data 11080. The difference data 11081 in this data is added to the end of the data. This is sorted when the CPU has enough time or in the PC 11040 as shown in FIG.

  FIG. 12 is an explanatory diagram showing a method of adding a difference to the original data as a version upgrade. Reference numeral 12000 is a standard example in which a difference is added to the original data. Difference data, difference 1, difference 3, and difference data are sequentially added. However, when the difference is added using the broadcast information according to the present embodiment, there is a possibility that the intermediate difference may be missed due to a bad radio wave condition. Reference numeral 12010 denotes an example in which reception of the difference 2 is missed. In this case, data after the difference 2 cannot be used. This embodiment is characterized in that it has a data structure that allows the subsequent difference data to be used even if an intermediate difference is lost. That is, when the first difference 1 is added to the original data, it is used in the form of original data + difference 1 as 12030. Next, when the difference 2 is received, the data of the difference 2 always includes the difference 1, and the version can be upgraded even if only the difference 2 is received. Here, the difference 2 is in the form of difference 1 + difference 2- (data that is no longer necessary in difference 1). In addition, in particular, a method for preventing trouble is adopted by adopting a method that does not make a difference for information whose absolute value is important such as an amount of money. Furthermore, since it is necessary to receive emergency information with certainty and it is necessary to be able to receive the original data even if it does not have the original data, a structure in which all data is transmitted without using the differential method.

  FIG. 13 is an explanatory diagram showing a method of receiving information transmission during communication by telephone in order to confirm again the detailed information of the information source in the cooperation between the reception of broadcast information and the reservation procedure in FIG. .
