DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

FIG. 1 is a diagram for explaining an embodiment of the present invention, and is a block diagram showing an example of a software service to which an application program broadcasting system is applied.

The application program created by software maker 2 is
It is broadcast on the radio wave through the program broadcasting station 1. The application program receiver 3 receives the designated application program among the broadcast application programs by the reception control program for controlling it, and loads it into the memory of the computer terminal 4. Reference numeral 5 denotes a broadcasting satellite, and the program transmitted from the application program broadcasting station 1 may be broadcast via the broadcasting satellite 5.

In FIG. 1, the computer terminal 4 and the receiver 3 are formed separately, but as shown in FIG. 2, the receiver 3 may be built in the computer terminal 201.
FIG. 2 is a block diagram showing a configuration example of a computer terminal 201 having the receiver 3 built therein.

In FIG. 2, 3 indicates the receiver shown in FIG. Reference numeral 6 denotes a CPU for controlling the entire computer terminal 201, 7 denotes a control program executed by the CPU 6 (see the flowchart of FIG. 4), and CP
It is a memory that is used as a work area when U6 operates and temporarily stores various data. In addition, this memory 7
The received application program is stored in, and the stored application program can be executed. 8 is a display such as a CRT or a liquid crystal, 9 is a coordinate on the screen of the display 8, and the like.
A pen for inputting various commands and instructions. 1
A keyboard 0 is operated by an operator and is used to input various commands and data. A demodulation unit 15 demodulates the received signal (for example, FM-modulated) and converts it into original digital data (code).

FIG. 3 is a diagram showing an example of the data format of transmission packet data of the application program of this embodiment. The transmission data is transmitted from the application program broadcasting station 1 by FM-modulating digital data, for example.

In FIG. 3, reference numeral 11 denotes a transmission code, which is a code transmitted from the application program broadcasting station 1. Reference numeral 12 indicates transmission information, and this information indicates that the following data is the application program 13. Reference numeral 13 denotes an area actually containing the code of the application program.

FIG. 4 is a flow chart showing an application program receiving process in the computer terminal 4 or 201 of this embodiment. This process is performed by receiver 3
A list of application programs currently being broadcast is received via, and the list is started in a state where it is displayed on the display 8.

First, in step S1, a program to be loaded into the memory 7 is designated from the program list displayed on the display 8 by using the keyboard 10 or the pen 9. In this way, when the application program is designated in step S1, the process proceeds to step S2, and the area of the memory 7 is secured to load the program. Then, in step S3, the application program specified in step S1 is received via the receiver 3, demodulated and stored in the memory 7 (step S3).
4).

The receiving operation in step S3 will be described in detail. The CPU 6 stores the application program name instructed in step S1 or a code specifying the program, and the transmission code received by the receiver 3 is stored. While monitoring 11 and the transmission information 12, it waits for the reception of the designated application program to start. Thus, when the receiver 3 detects that the reception of the application program is started, the broadcasted data is received, demodulated, and stored in the memory 7 while being converted into original digital data.

In this case, if the date and time when the desired application program is broadcast is known in advance from the broadcast program program table or the like, the program reception may be started at that date and time (timer). Reservation).

When all the application programs instructed in step S5 have been received and stored in the memory 7 in this way, the process is terminated.

Thus, with the desired application program stored in the memory 7, the keyboard 10
By instructing the execution of the application program, the application program can be executed on the computer terminal 4 or 201. Then, when the application program is no longer needed, the memory 7 can be effectively used by deleting the application program from the memory 7. After that, if the application program is needed again, the broadcasted application program may be received again.

FIG. 5 is a schematic diagram showing the relationship among the user 501, the software maker 2, the application / program broadcasting station 1, and the hardware maker 502.

The user 501 pays for the software to the maker 2 who has developed the desired application program, and in exchange, obtains parameter software, a password, etc. for receiving the broadcast application program. . Further, between the software maker 2 and the application program broadcasting station 1, instead of providing the broadcasting software from the manufacturer 2 to the broadcasting station 1, the broadcasting price of the software is paid from the broadcasting station 1 to the manufacturer 2. User 501 and this broadcasting station 1
In between, the user 502 pays the reception fee for receiving the broadcast to the broadcast station 1, while the user 501 can receive the broadcast service of various programs from the broadcast station 1.

In addition to the above, a transmitter is provided to the application program broadcasting station 1 by the hardware manufacturer 502, and in exchange, the transmitter is provided by the application program broadcasting station 1.
Will be paid for. The user 501 also pays the hardware maker 502 to purchase the receiver 3, the computer terminal 4, and the like.

The present invention may be applied to a system composed of a plurality of devices or an apparatus composed of a single device. Further, it goes without saying that the present invention can also be applied to the case where it is achieved by supplying a program for implementing the present invention to a system or an apparatus.

As described above, according to this embodiment, the application program required by the user can be received as many times as necessary and read into the memory for use. This ensures that the application
It is not necessary to store the program, and a storage medium for storing the application program such as a large-capacity external storage device becomes unnecessary. In this way, various application programs can be easily executed on the smallest scale device or terminal.

[0027]

As described above, according to the present invention, a desired application can be realized without a large capacity memory.
The program can be executed freely.

Further, according to the present invention, there is an effect that various application programs can be broadcast and the terminal can receive the programs and execute the application programs.
