The operation of the digital broadcast receiver configured as described above will be described below.

First, the received digital data 1 is E
It is input to the PG data extraction device 2. The EPG data extraction device 2 extracts a TS relating to the EPG data in the digital data 1 and outputs it as EPG data. The extracted EPG data 3 is input to the search device 5.

On the other hand, when using a program information providing service for searching and displaying a viewer's favorite program with a receiver, it is necessary to previously register the viewer's favorite program data as viewer information in a digital broadcast receiver. . This registration of the viewer information can be performed by a conventional remote control operation. The registered data of the viewer information is stored in the viewer information storage device 4. The viewer information storage device 4 is composed of a readable and writable storage element. The viewer information stored in the viewer information storage device 4 is also input to the search device 5 when using the program information providing service.

Next, the operation of the search device 5 will be described with reference to FIG. The EPG data of FIG. 2 is the EPG data 3 of FIG.
The viewer information of FIG. 2 specifically shows the content of the viewer information stored in the viewer information storage device 4 of FIG.

The EPG data includes program classification information. For example, "100 baseball, 402
It is assumed that three classification data of “local, 503 variety” are stored. The number here is key information used for the search. When the viewer information is input to the search device 5, the search device 5 searches for program classification information in the EPG data based on the key information. When key information is found from the program classification information, all programs belonging to the searched key information are output. In the example of FIG. 2, as the viewer information, all programs in the category of “baseball, local, variety” are acquired from the EPG data. All the programs are output from the search device 5.

The program information output from the search device 5 is delivered to the viewer 7 via the output means 6. The viewer 7 obtains favorite program information from the output means 6, and can freely select a program from the information.

FIG. 3 shows an operation example from the output of the search device 5 in FIG. 1 to the extraction of the program classification output of the collation device 9, and the viewer who has obtained the search result from the search device 5 from the output means is the viewer. Select a program from among them. For example, when the viewer 7 wants to select "comedy program E", the program selection input means 8 (for example, a remote controller of the receiver) inputs a selection code of this program.

The program selected by the program selection input program 8 is compared with the classification code of the program classification information in the EPG data by the collation device 9 with the selection code. Since the selection code used for the program selection input includes information on the classification to which the program belongs, the collation device 9 can collate the selected code with the program classification information and output the classification information. For example, when the selection code “503-0” of “comedy program E” is input, the collation device 9 outputs the classification data “503” of the program classification information.
Recognition is made as "variety", and the classification result of "503 variety" is output.

In the example shown in FIG. 3, program data belonging to the viewer information category is selected. However, there may be cases where it is desired to view programs other than the viewer information category. Even in that case,
First, if the user inputs "other"("000other" in FIG. 3) and enters a selection code belonging to the other classification, the classification information can be easily collated by the same collation method. The classification result of the viewed program output from the matching device 9 is input to the viewer information editing device 12.

Next, the operation of the viewer information editing device 12 will be described with reference to FIG. FIG. 4 is a diagram showing an example of the operation of the viewer information editing device 12 of FIG. The viewer information editing device 12 includes the viewer information storage device 4, the viewing history processing device 10, and the viewing history storage device 11 of FIG.

The classification result of the viewed program output from the collating device 9 is first input to the viewing history processing device 10.

Specifically, each time a classification result is input from the matching device 9, the number of times of viewing of the corresponding classification is incremented by one. The result of the viewing frequency is sequentially stored in the viewing history storage device 11.

For example, in FIG. 4, when "200 Japanese Movies", which is not the audience information classification, is input from the collation device 9, the viewing history processing device 10 increments the viewing frequency of the "200 Japanese Movies" classification by one. The top several classifications with the highest viewing frequency are checked, and if there is a change in the higher ranking, it is written in the viewer information storage device 4. In FIG. 4, the viewing frequency of “200 local movie” is higher than that of “402 local”, which is the viewer information, so that “402 local” of the viewer information is automatically updated to “200 local movie”.

The next time the viewer uses the program information providing service, the program can be searched based on the updated viewer information.

In the example of FIG. 4, the viewer information registered by the viewer is updated by overwriting the viewer information, and the viewer information registered by the viewer is changed.
