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.

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. Less than,
Along with road information, such as information on dead ends due to road construction, etc., information on bazaars, and shoes. 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 is a logical operation result of a plurality of keywords, for example, (umbrella) AND
You may specify in the form of (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. 12 is an explanatory diagram showing a method of adding a difference to the original data as a version upgrade. 12000 is a standard example in which a difference is added to the original data. Difference 1, difference 2, difference 3
Difference data is added sequentially. 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.
