FIG. 4 is a block diagram showing the outline of the operation of the data broadcasting transmission / reception system, and FIG.
6 is a flowchart showing an example of an operation by a control program stored in OM15. When the data broadcasting receiving terminal 2 is turned on and the operation is started, various initialization processing of the data broadcasting receiving terminal 2 is executed (step S1). In this initialization processing, self-diagnosis and reception preparation work of the data broadcast receiving terminal 2 are performed. As soon as the preparation for reception is completed, the corresponding data transmitted by the center device 1 is received according to the channel set in the RAM 16 in the data broadcast receiving terminal 2 (step S2) (step S3). Until the corresponding data is received, the processing returns to step S2 and is repeated. After receiving the corresponding data, it is determined whether the data is designated data or not (step S4), and R in the data broadcast receiving terminal 2 is determined.
Data that needs to be compared with the terminal ID registered in the OM 15 is subjected to comparison processing (step S5) and classified into the patterns of steps S51 to S5N. If the data is not designated data, step S4
Then, the process proceeds to data registration (step S6). The comparison process in step S5 is performed by R in the data broadcast receiving terminal 2.
It is performed by a plurality of comparison means such as pattern classification by the last 1 digit of the terminal ID registered in the OM 15 and classification of lottery success / failure by the last few digits of the data, and different data for each terminal depending on each classification result. Is selected, and the process proceeds to data registration (step S6). Both the selected data and the data processed differently in step S4 are registered in the RAM 16 in the data broadcast receiving terminal 2 (step S6). Further, these registered data are displayed on the display of the data broadcast receiving terminal 2 or an externally connected CRT or the like (step S7).

This is because the comparison process (step S5) performed in the flowchart shown in FIG. 5 is set in the RAM 16 in the data broadcast receiving terminal 2 such as "gender""age""married""jobtype""address". The comparison process is performed based on the personal profile data. In this case, the ROM
It is not necessary to register individual terminal IDs in 15 at the time of terminal shipment. Referring to FIG. 6, after step S4, a comparison process (step S8) with the personal profile data set in the RAM 16 in the data broadcast receiving terminal 2 is performed, and the comparison process in step S8 is performed. Is, for example, “employee in his 20s” or “housewife in his 30s”. Only data that matches the personal profile set in the RAM 16 in this comparison process is selected as display data and is the same as in the above-described embodiment. Then, processing such as registration and display is performed.

(Embodiment of the Invention of Claims 1, 4 and 5 to 7) FIG. 7 shows an embodiment of the present invention, in which an operation by a control program stored in the ROM 15 shown in FIG. It is a flowchart which shows an example. This is performed by comparing the comparison process (step S5) performed in the flowchart shown in FIG. 5 with random number data generated by a random number generation routine registered as a program in the ROM 15 in the data broadcast receiving terminal 2. It is a thing. In this case, the individual terminals I are stored in the ROM 15.
A similar service such as lottery can be performed without registering D at the time of shipping the terminal. Looking at this in the flow chart of FIG. 7, the process up to the designated data is performed as in the flow chart of FIG. 5 (step S4). Random number data is generated by the program in the ROM 15 (step S9). Next, a comparison process is performed between the received data and the random number data generated in step S9 (step S10). In this comparison process, the pattern classification according to the designated number of digits of the random number data or the lottery result of the random number data itself is judged. This is performed by a plurality of comparing means such as classification, and different data is selected for each terminal according to the respective classification results, and processing such as registration and display is performed as in the above-described embodiment.

【The invention's effect】

Invention of Claim 1: Data transmission to a specific terminal or user, which was possible only by communication, becomes possible by allowing the terminal side to select the data specified by the center side even if a broadcast wave is used. . Invention of claim 2: In addition to the effect of claim 1, the receiving terminal can be designated on the side of the center device (on the side of the information sender). Invention of claim 3: In addition to the effect of claim 1, the center device side (information sender side) can specify a user and deliver to a specific target. It is possible to obtain the requested information. Invention of Claim 4: In addition to the effect of Claim 1 described above, broadcasting of a new genre of terminal lottery using broadcast waves becomes possible. Invention of Claims 5 to 7: In addition to the above effects of Claims 1 to 4, it is possible to select automatically designated data or information, and only the selected data or information is processed (recorded) and displayed. As a result, the burden on the processing device such as the pressure on the RAM due to the conventional unnecessary data that has processed all the data does not increase, and it becomes possible to release from the troublesome work such as selection of data.
