Abstract

PROBLEM TO BE SOLVED: To facilitate program updating and also to attain updating the programs of plural terminal equipments by executing electric wave broadcasting through the use of electric wave by which wide range of transmission is possible and, in the meantime, updating the program based on broadcasting electric wave. SOLUTION: When information such as the retrieval display program, etc., of information portable terminal equipments 3-n is desired to be updated through the use of a computer device 1, transmission-prepared information is transmitted to an electric wave broadcasting device 2. Then, information transmitted from the computer device 1 is demodulation-processed by the electric wave broadcasting device 2 with a broadcasting instruction from the computer device 1 as a sign and electric wave broadcasting is executed through the use of electric wave by which wide range of transmission such as an FM character broadcasting, etc., is possible. The reception possible information portable terminal equipments 3-n receive electric wave broadcasted from the electric wave broadcasting device 2, demodulation is executed and information is returned to be the one before modulation. Since the electric wave broadcasting device 2 repeatedly broadcasts transmission-prepared information by the computer device 1, the programs of the plural information portable terminal equipment 3-n are updated.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an information portable terminal system according to an embodiment of the present invention will be described with reference to the drawings. FIG.
1 is a diagram showing an information portable terminal system according to an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a computer device for controlling transmission of information such as programs and data, reference numeral 2 denotes a radio wave broadcasting device for transmitting information prepared for transmission by the computer device 1, and reference numerals 3, 4,. Is an information portable terminal device capable of receiving a radio broadcast broadcasted by the radio broadcast device 2. 2 and 3 are block diagrams showing the configurations of the computer device 1, the radio broadcast device 2, and the portable information terminal device 3. As shown in FIG. 2, the computer device 1 is a control unit 1 that controls each unit constituting the computer device 1
1, a storage unit 12 including a ROM, a RAM, a hard disk, and the like, and an operation unit 1 including a keyboard, a mouse, and the like.
3, a display unit 14 for displaying, and an interface unit 15 for connecting to the radio broadcasting apparatus 2 and performing transmission control. 2, the radio broadcast apparatus 2 includes an interface section 21 for connecting to the computer apparatus 1 and a transmission section 22 for performing modulation processing and performing radio broadcast. 3, the portable information terminal device 3 stores a control unit 31 for controlling each unit of the portable information terminal device 3, a radio wave receiving unit 32 for receiving a radio wave broadcast from the radio wave broadcasting device 2, and a search display program. Search display program storage 3
3. A search display data storage unit 34 for storing search display data, an operation unit 35 including operation buttons and the like, and a display unit 36 for displaying data search results and the like.

Next, the operation of the portable information terminal system will be described. First, the computer 1 is used to prepare for sending information such as a search display program to be updated to the portable information terminals 3 to n. If the information to be prepared is a search display program, the version information of the program is included in addition to the program. Further, in the case of data, in addition to the search display data, the data version and the version information of the search display program corresponding to the data are included. The information prepared for transmission is stored in the storage unit 12. Next, under the control of the control unit 11, the computer device 1 transmits the information prepared for transmission from the storage unit 12 to the radio wave broadcasting device 2 via the interface unit 15. The radio broadcast device 2 receives information transmitted from the computer device 1 via the interface unit 21. In response to a broadcast command from the computer device 1, the transmitting unit 22 modulates information transmitted from the computer device 1 and performs radio wave broadcasting using radio waves that can be transmitted over a wide range, such as FM text broadcasting. .

The receivable information portable terminal devices 3 to n receive the radio wave broadcast from the radio wave broadcasting device 2 by the radio wave receiving unit 32. The radio wave received by the radio wave receiving unit 32 is demodulated and returned to information before modulation. If it is a program, the search display program is stored in the search display program storage unit 33 together with the version information of the program. If the demodulated information is data, it is stored in the search display data storage unit 34 together with the data version and the version of the search display program corresponding to the data. However, if the demodulated information is a program and is the same as the version of the program stored in the search display program storage unit 33, it is assumed that the information is not stored again.
Similarly, if the data is the same as the already stored data version, the data is not stored again. If the search and display program version corresponding to the data stored in the search and display data storage unit 34 does not match the program version stored in the search and display program storage unit 33, the data, Alternatively, it is assumed that the operation of the portable information terminal device 3 becomes possible after the program is updated and the versions match. With the portable information terminal device 3 that can be operated, the operator operates the operation unit 35 to search for search display data using the search display program, and the display unit 3
It becomes possible to see the result searched in step 6. As described above, since the radio wave broadcasting device 2 repeatedly broadcasts the information prepared for transmission by the computer device 1, the receivable information portable terminal devices 3 to n receive the radio wave broadcast,
Update the program. Therefore, the display search program of a plurality of portable information terminal devices can be updated. Further, since the search and display program can be updated by receiving the radio broadcast, the search and display program does not have to be stored at the beginning of the manufacture of the portable information terminal device.

In the portable information terminal system of the above embodiment, the search and display program is described as an example of a program to be updated. However, other processing programs may be used as programs to be updated in the portable information terminal. Good. In the portable information terminal system in the above embodiment, the radio wave broadcasting device 2 repeatedly broadcasts the information prepared by the computer device 1, and the receivable information portable terminal devices 3 to n receive the radio wave broadcast and display and search. The program is to be updated. Instead of this method, before starting broadcasting, the radio broadcast apparatus 2 first broadcasts an activation signal that enables the information portable terminal apparatuses 3 to n to update information, and then broadcasts information to be updated. I do. On the other hand, the portable information terminals 3 to n always monitor the radio waves being broadcast, and
The program may be updated by fetching and demodulating a radio wave broadcasted by a signal from a start signal from.

[0010]

As described above, according to the portable information terminal system of the present invention, the following effects can be obtained. (1) Radio wave broadcasting devices perform radio wave broadcasting using radio waves that can be transmitted over a wide range, while information terminal portable devices update programs based on the broadcasted radio waves. Programs of a plurality of portable information terminal devices can be easily updated. (2) Since the radio wave broadcast by the radio wave broadcasting device is only one-way transmission, the program can be updated without the device transmitting the program and the device receiving the program facing each other.
