2. Description of the Related Art Advances in communication technology and data processing technology have made multimedia information composed of audiovisuals digitally broadcast and provided to users. In addition, an EPG (Electric Program Gui) for selecting a desired program from digital multi-channel broadcasting
A system called de) has also emerged. Conventional 1
In the method of selecting a favorite program from a program list that extends over a week, a lot of time and effort is required. On the other hand, in the EPG system, a viewer selects a menu displayed on the EPG screen by remote control operation. A desired program can be quickly selected by searching or the like. An example of a conventional EPG system is described in Japanese Patent Application Laid-Open No. 9-542037. In this conventional example, the reception frequency of the user is grasped from the reception time of the received program so as to be referred to as a "favorite program", and a program having a high frequency is registered as a favorite program in one group. You have selected a program you want to receive only from inside.

[0003]

However, according to the above-mentioned prior art, there are the following problems. (1) When a program to be received is selected from a favorite program group, it is difficult to grasp what program is being performed in the same time zone. The reason is that when a group of favorite programs is displayed on the screen, other received program information of the same time zone cannot be seen. (2) Media other than TV, such as data broadcasting, cannot be handled. The reason is that the reception time is used as a means for grasping the reception frequency. (3) As a favorite program, a program that is always received is added to the registration list, but it is difficult to find another program by prompting the user to select a favorite performer. The reason is that only the received program is set as a favorite program.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has been made to solve the above-mentioned problems.
In various broadcasting modes such as broadcasting, data broadcasting, and Internet broadcasting, the user's preference is analyzed, and a channel or a program likely to be selected by the user is visually enhanced by using a program display or a channel selection button in the EPG.

[0006]

FIG. 1 is a block diagram showing an embodiment of the present invention. As apparent from FIG. 1, the program information customizing apparatus of the present invention includes a broadcast receiving apparatus 1 for receiving a TV broadcast such as a satellite or a terrestrial wave, a data processing apparatus 2 operating under program control, It comprises a storage device 3 for storing information and an output device 4 such as a TV screen or a display device of a personal computer.

[0007] The broadcast receiving apparatus 1 receives information of a broadcast program being received and information of an EPG, and supplies them to the data processing apparatus 2. Here, the broadcast program information is information such as a genre and a synopsis that can be obtained by comparing channel information selected by the tuner with information obtained from the EPG. In the case of a song title introduction data broadcast being broadcast, which is used in FM text multiplex broadcasting and the like, the content of the data broadcast becomes program information as it is.

[0008] The data processing device 2 comprises an EPG analysis means 2
1, received program analysis means 22, user preference analysis means 23,
User reception program prediction means 24, EPG display determination means 2
5. It comprises a reception expectation determination means 26. The storage device 3 includes a received program storage unit 31 and a user preference storage unit 32. The received program analysis means 22 constituting the data processing device 2 converts the information obtained from the broadcast receiving device 1 into a database based on a certain standard. Figure 8 shows the database entry structure
The results are shown in Table 1. Each entry contains media type, program broadcast time, channel, program name, genre, cast,
The content is configured as a data string. Here, for example, a program whose reception time exceeds a certain reference or a number of times that the program is selected and a program that exceeds a certain data amount are valid as data. Here, a database is created and stored in the reception program storage unit 31. It is memorized.

[0009] Depending on the type of program, the actual reception time may be reduced as much as possible by the method of compressing and transmitting the data, or some programs may always have a constant content. Therefore, as shown in Table 2 in FIG. The reference value is set in accordance with various media characteristics and channel characteristics. Table 2 in FIG. 9 shows an example of the reception condition criteria, and exemplifies the viewing validity criteria for each type of media. By setting the reference value, it is not necessary to be aware of media and channels having different characteristics, and a program can be selected in the EPG. The reference setting method shown in Table 2 of FIG. 9 is determined by a method of feeding back the information obtained by the user preference analysis means 24 and the result obtained by the reception expectation determination means 24 for comparing the actually received program. . The method of the feedback will be described in the item of the reception expectation determining means 26 in the operation description to be described later.

[0010] The received program storage section 31 is where data that exceeds a certain standard is stored by the above-mentioned received program analysis means 22. The user preference analysis unit 23 analyzes the user preference using the information stored in the received program storage unit 31. Specifically, first, the program that the user regularly receives is extracted. This is because when the same data is stored in the information of the received program storage unit 31 every day or about once a week, the program is referred to as a “periodically received program”.
Recognize as Further, by analyzing a received program database as shown in Table 1 in FIG. 8, the user's taste is predicted. If there is similar data for the “genre” or “performer” of the program, it is regarded as favorite data. However, "Genre" and "Performers"
The importance of each data sequence differs for each individual.
For example, there is a case where a user's reception standard often depends on “performers”. Therefore, weighting is performed for each data sequence, and user preference is predicted. Further, the result of the reception expectation judging means 26 is fed back to optimize the weighting. Also, in analyzing the data here, by cooperating with the interaction between data and dictionaries, etc.
There are also ways to analyze user preferences in more detail.

[0011] The user preference storage section 32 stores information obtained by the user preference analysis means 23. The user reception program predicting means 24 predicts a program which will be received from now on the basis of the user preference storage means 32. From the data of the received EPG, programs having high receivability are selected in consideration of the characteristics of the program, and grouping is performed in descending order of receivability. What is shown as Table 3 in FIG. 10 is an example of grouping, and shows program characteristics for each group. Here, for example, group 1 is a program that is broadcast regularly for a limited time every day among programs that are received regularly, and group 6 is a program that is broadcast for 24 hours and is a program that is prompted by the user's preference. . Of course, the present invention is not limited to this example, and may be grouped in more detail, or may be quantified.
In addition, by performing grouping in consideration of the characteristics of the program, scheduling of the received program is enabled. That is, for a 24-hour broadcast program,
This is because a method such as reception in a vacant time can be adopted.

The EPG display determining means 25 expresses the information grouped by the user received program predicting means 24 by visually emphasizing the information. As a method of visual enhancement, on the display screen of the EPG, a contrast or size is changed for each program or channel, or a three-dimensional image is formed. For example, the program most likely to be received is displayed with increased contrast. Conversely, many programs that are unlikely to be received are displayed with reduced contrast.

As described above, by displaying, it is more difficult to select an item having a high possibility of receiving, and to select an item having a low possibility of receiving. This makes it easy for the user to select a program that he or she wants to receive in the same time zone, while displaying programs that are unlikely to be received. Furthermore, by arranging programs that are likely to be received on a time axis, a reception schedule can be automatically set.

The reception predicting means 26 is provided for the received program analyzing means 22.
Then, the processing of the user preference analysis unit 23 is modified.
First, a program received within a certain period of time is compared with a program expected to be received within a power-on time, and the matching rate is defined as a hit rate. The received program analyzing means 22 recognizes the received condition and is registered in the database, and the user preference analyzing means 23 uses "genre" and "performers".
Optimization is performed by changing the numerical value of the importance for each data string. As an optimization method, for example, an experimental design method which is a statistical method is used. Using the condition value or the like of leaving the data of the received program analysis means 22 in the history as one factor, the change of the hit rate due to the change of the factor is analyzed to determine the optimal setting. The output device 4 is an EPG
The information determined by the display determining means 25 is output to a display or the like.

FIGS. 2 to 5 are diagrams cited for explaining the operation of the embodiment of the present invention. FIGS. 2 and 3 show a process for analyzing a received program and a process for analyzing user preference, respectively. The flowcharts shown in FIGS.
4 shows a configuration example of a PG display screen. Hereinafter, the operation of the embodiment of the present invention shown in FIG. 1 will be described with reference to the flowcharts shown in FIGS. 2 to 5, the EPG display screen, and FIGS.
This will be described in detail with reference to the table shown in FIG.

First, the broadcast receiving apparatus 1 receives information on a broadcast program being received and information on an EPG. The information of the broadcast program can be known by comparing the selected channel with the information obtained from the EPG. If a program can be specified, information such as performers, genres, and synopses can be obtained from the EPG.
In the case of a song title introduction data broadcast being broadcast, which is used in FM text multiplex broadcasting and the like, the content of the data broadcast becomes program information as it is. The obtained information is set up in a database based on a certain standard. The structure of the database is shown in Table 1 in FIG. For example, a program whose reception time exceeds a certain standard becomes valid as data and remains as a history. However, depending on the type of program, the method of compressing and transmitting data may be used to reduce the actual reception time as much as possible, or the reception time may be short even if the program is viewed frequently, such as a weather channel. Some programs, such as programs and satellite data broadcasts, always have a fixed content. Therefore, as shown in Table 2,
Due to various media characteristics and channel characteristics,
Set the reference value for each.

As shown in the flowchart of FIG. 2, the received program analyzing means 22 grasps the received program (step S1).
1) and confirm the total reception status of the program (step S
12) After that, it is determined whether or not the data is valid according to the condition of each medium (step S13). In order to check the total reception status, there is a method of simply using the total reception time of the channel. However, since data may be simultaneously transmitted on the VBI or the subcarrier, the total number of packets is also determined. be able to. In the case of data broadcasting and the like, it is determined whether or not data has been normally received.

The reference setting method shown in Table 2 of FIG. 9 may be set by the user or may be set in advance. This is performed by feeding back the obtained information and the result obtained by the reception expectation determining means 24 for comparing the actually received program (step S18). Here, the preference of the user is analyzed using the information of the received program storage unit 31. The process for user preference analysis by the user preference analysis means 23 will be described with reference to FIG. First, the program that the user regularly receives is extracted (step S21). Here, the received program storage unit 3
One of the information, "Media type""Channel"
For the "program name", it is determined whether or not the same data is stored every day or whether or not the same data is stored about once a week, and the program is recognized as a "regular reception program". It is stored in the user preference storage unit 32.

In addition to the regularly received programs, the user often selects a program in which a talent that suits his / her preference appears, or a program whose contents match the hobby. Therefore, FIG.
By analyzing the received program database as shown in Table 1 above, the user's taste is predicted. If there is similar data about the genre of the program or the cast,
It is regarded as favorite data (step S22).
However, the importance of each data string such as “genre” and “performer” differs for each individual. For example, "genre"
There is a possibility that the weight of the data is different depending on whether the sport was received twice and whether the same talent was selected twice in the “performers”. Therefore, the user's preference is accurately grasped by weighting each data string (step S23). Furthermore, in order to accurately grasp the user's preference, the weight of the data is changed based on the actual reception status (step S18). In analyzing the data, it is also possible to analyze the user's preference in more detail by cooperating with a dictionary or the like. For example, if the word “soccer” is included in the program content, it is recognized as a sports related item, and the “genre”
It is added to the data of sports.

The user-received program predicting means 24 selects a program having high receivability from the EPG data analyzed by the user preference storing means 32 and the EPG analyzing means 21.
The selected programs are grouped in descending order of reception possibility (see Table 3 in FIG. 10). When performing some grouping as shown in Table 3 of FIG. 10, it is necessary to consider the characteristics of the program. For example, broadcasts that are broadcast for a limited time cannot be received later, so it is necessary to raise the priority of reception. If no grouping is performed, user preferences may be quantified.
By considering the characteristics of the program in this way, it is possible to schedule the received program.

The EPG display determining means 25 expresses the information grouped by the user received program predicting means 24 or the numerical data by visually emphasizing the information.
As a method of visually enhancing, on the display screen of the EPG, a contrast change, a size change, a three-dimensional change, and the like are performed for each program or channel. For example, as shown in FIG. 4, for a program most likely to be received, the contrast is changed and displayed (hatched expression). By displaying in this manner, a program that is more likely to be received is more difficult to select, and a program that is less likely to be received is more difficult to select. Also, on the channel selection screen in which the user selects only the channel, the channel expected to be received is displayed large as shown in FIG. In the EPG screen shown in FIG. 4, a channel number is shown horizontally and a time axis is shown vertically. In the EPG screen shown in FIG. 5, block representations having different sizes for each channel number are made.

In the reception predicting means 26, the received program analyzing means 2
2 and by modifying the processing of the user preference analysis means 23 to optimize the user preference. First, a program received within a certain period of time is compared with a program expected to be received within a power-on time, and the matching rate is defined as a hit rate. The hit rate is used as a criterion for determining whether or not the user's preferences are accurately grasped. In order to increase the hit rate, for example, an experiment design method used in a statistical method is performed. An experimental design is an analysis of what factors affect the results by changing some factors, and the interaction between the factors, and how to change the factors to find the optimal solution. It is a method to derive from the experiment whether it can be obtained. Here, the factor is a condition value which is recognized by the received program analysis means 22 as being received and registered in the database, and the user preference analysis means 23 indicates a degree of importance for each data string such as "genre" and "performer". It is a numerical value. By changing these factors several times, the effect of each factor can be grasped.
If "performers" had a big effect,
Increase the importance of "performers" data. In this way, the hit rate is increased and the optimal setting is made.

The flowcharts shown in FIGS. 2 and 3 are as follows.
All show the processing procedure by software, semiconductor storage, floppy disk, magnetic disk,
Programmed and recorded on a recording medium such as a CD-ROM,
Alternatively, the above-described desired processing is performed by reading and executing the program downloaded via the communication line by the CPU built in the data processing device 2 shown in FIG.

FIGS. 6 and 7 are block diagrams showing another embodiment of the present invention. The embodiment shown in FIG. 6 is an example of the configuration of a program information customizing device that is more conscious of the Internet. The Internet terminal 5 receives EPG information distributed on the Internet and supplies it to the data processing device 2. Here, the homepage of the Internet is also regarded as one broadcast program, and the received program analysis means 22 determines whether or not to leave a history as data. Other blocks and subsequent operations are:
Since this embodiment is the same as the embodiment shown in FIG. 1, the description here will not be made to avoid duplication.

The embodiment shown in FIG. 7 is an example of the configuration of the program information which allows the user to change his / her preference according to the change of the user and the mental state of the user at the time of reception. Here, information such as “depressed” and “during reading” of the current user is input from the input device 6.
The user preference analysis unit 24 weights the data according to each case, and stores the user preference for each user state. Therefore, in the user preference storage unit 32, a database prompting each state is created,
This is reflected in the selection of the received program.

[0026]

As described above, the present invention analyzes the user's preference in various types of broadcasting such as digital TV broadcasting, data broadcasting, and Internet broadcasting to be multi-channeled, and selects a channel highly likely to be selected by the user. Alternatively, by visually highlighting the program display and the channel selection button on the EPG, the user can easily search for a received program or a receiving channel and set a receiving schedule according to the user's preference. The following effects can be obtained. (1) The user can easily select a favorite program and channel while comparing it with other programs. The reason is that, in the EPG display for program selection, programs that are likely to be selected by the user are visually emphasized. (2) Programs can be selected within the same EPG without being aware of the characteristics of various broadcast media and channels. The reason is that processing is performed according to characteristics of various media and channels. (3) The program that the user will receive can be accurately predicted. The reason for this is to enable the optimization by anticipating the user's preference and comparing it with the actual received program.
