Step S402: The device control unit 126 mounted on the CPU 118 controls the TS decoder 103 to cause the EI of the channel currently being viewed by the user.
Get Ta_pf.

Step S403: The CPU 118 determines whether or not the same channel is being viewed for 3 minutes or longer by a timer (not shown). If the same channel has not been viewed for 3 minutes, the CPU 118 returns to step S402 again. return,
The acquisition operation of EITa_pf of the corresponding channel is executed. On the other hand, if the same channel has been viewed for 3 minutes, the process proceeds to the next step S404.

Step S404: The device control section 126 mounted on the CPU 118 controls the TS decoder 103 to describe the current time information (information such as date, hour and minute) TOT (Time Offset). Table) or T
Obtain DT (Time Date Table). Step S405: The section decoder 106 sends CP
E obtained by the TS decoder 103 under the control of U118
Each descriptor information described in ITa_pf is decoded (analyzed), and the result is sent to the viewing history data management unit 119 mounted on the CPU 118.

Step S406: The viewing history data management unit 119 uses the descriptor information described in the EITa_pf decoded by the section decoder 106 to obtain the required attribute information, that is, the program name, program genre, and program performer name. Information is extracted, and the viewing history management table 300 of FIG. 3 is generated and updated based on these information. Whether the extracted attribute information is already registered in the viewing history management table 300 or not. To determine. As a result of this determination, if it is registered, the process proceeds to step S407, and if it is not registered, the process proceeds to step S409.

Step S407: As a result of the determination in step S406, the extracted attribute information is already in the viewing history management table 3.
If it is registered as 00, the viewing history data management unit 11
9 is a corresponding count value in the viewing history management table 300 (co indicating the number of times the same attribute data is extracted.
unt_value) is incremented. For example, if the extracted program name has already been registered, its count value (coun
t_value) indicates the number of times a program having the same program name has been viewed, and therefore is incremented by +1 assuming that the program has been newly viewed.

Step S408: The viewing history data management section 119 updates the date information (last_count_date) in the viewing history management table 300, which corresponds to the attribute information whose count value was updated in step S407. For example, if the extracted program name has already been registered and its count value (count_value) has been updated, the corresponding date information (last_count_date) will be updated with the last date of viewing the program with the same program name. To do. As a result,
For example, in FIG. 3 described above, the program name “Professional baseball relay 3” indicated by INDEX1-1 has been viewed 48 times so far, and the last viewed was April 13, 2000. The viewing history will be registered. Similarly, the viewing history that the program genre "domestic drama" indicated by INDEX2-5 has been viewed 156 times so far, and the last viewed was April 20, 2000. Will be registered. Also, IN
For the program performer name "Sakagami ● rou" indicated by DEX3-4, the program in which "Sakaue ● rou" has appeared has been watched 56 times so far, and the last watched was in 2000 The viewing history that the date is 18th of a month is registered.

Step S409: As a result of the determination in step S406, the extracted attribute information is the viewing history management table 300.
If not registered in the viewing history data management unit 119
Determines whether the extracted attribute information can be newly registered in the viewing history management table 300. Specifically, the viewing history data management unit 119 determines whether the viewing history management table 300 has a sufficient index and a new registration is possible. As a result of this determination, if new registration is possible, the process proceeds to step S410, and if new registration is not possible, the process proceeds to step S411.

Step S410: As a result of the determination in step S409, the extracted attribute information is added to the viewing history management table 300.
If the viewing history management table 300 has an empty index, the viewing history data management unit 119 newly registers the extracted attribute information in the empty index.

Step S411: As a result of the determination in step S409, the extracted attribute information is set to the viewing history management table 300.
If new registration is not possible in the viewing history management table 300, that is, if there is no free index in the viewing history management table 300, the viewing history data management unit 119 sets the date information (last_count_date) of the attribute information registered in each index in the viewing history management table 300. Is read out and the last update (registration) date and time of the count value (count_value) is investigated by comparing this date information (last_count_date) with the current time information acquired as described above.
Then, as a result of the above-mentioned investigation, the viewing history data management unit 119 determines that the count value (c
ount_value) determines whether there is any attribute information that has not been updated. As a result of this determination, the count value (count_valu
If there is attribute information for which e) has not been updated for the predetermined period, the process proceeds to step S412, and the count value (count_valu
If there is no attribute information that has not been updated in e) for the predetermined period, the process proceeds to step S413.

Step S412: As a result of the determination in step S411, when there is attribute information for which the count value (count_value) has not been updated for a predetermined period, the viewing history data management unit 119 causes the attribute information to have low preference for the viewer. It is determined that the attribute information is the program attribute information, and the newly extracted attribute information is newly registered (overwritten) in the index portion of the attribute information.

Step S413: As a result of the determination in step S411, when there is no attribute information whose count value (count_value) has not been updated for a predetermined period, the viewing history data management unit 119 registers the oldest date information (last_count_date). In the index part that has the attribute information
The newly extracted attribute information is newly registered (overwritten).

In the present embodiment, only the attribute information relating to the programs viewed by the viewer for 3 minutes or more is registered in the viewing history management table 300, and the information is registered for a predetermined period.
Update count value (count_value) (count up)
The attribute information (event_name, event_genre, event_performer) registered in the index that was not deleted was configured to be deleted (overwritten). Regarding the viewing time (3 minutes etc.) and the predetermined period (1 month etc.) at this time Is not limited to this, and any value such as 1 minute, 5 minutes, 1 week or 3 months can be applied.

The viewing history management table 300 generated and updated by the viewing history data management unit 119 as described above is stored in the history data storage unit 117 in the memory 116, but the memory 116 is non-volatile. The semiconductor memory, the hard disk, or the like can be applied.
