<Configuration of digital broadcast receiver>
FIG. 1 is a block diagram of a digital broadcast receiving apparatus. The digital broadcast receiving apparatus 1 receives a digital broadcast program (digital TV signal) so that the viewer can select a program that the viewer desires to watch accurately and quickly. Program information storage means 5, decoding means 7, main control means 9, composition switching means 10, operation means 11, selection pattern storage means 13, viewer personal information storage means 15, time zone channel table storage Means 17, genre coefficient table storage means 19 of interest, factor basic value table storage means 21, information life pattern table storage means 23, factor correction dictionary storage means 25, and broadcast station correction value table storage means 27. I have. The digital broadcast receiver 1 is connected to a display device 2 that receives and displays a program selected by the viewer.

  The program receiving means 3 receives a digital broadcast program (digital TV signal) transmitted through the ground wave, satellite wave, cable television network or communication line network, and outputs it to the decoding means 7. Means 3a are provided. The program receiving means 3 switches the received digital broadcast program based on the control from the main control means 9 and outputs it to the decoding means 7.

  The program information separating means 3a separates program information (SI [service information]) included in the digital TV signal. The program information separated by the program information separation means 3a is output to the program information storage means 5. The program information is information related to the program, the program name describing the program, the description of the program (summary), the performer, the screenwriter (director), etc., the broadcast time and the end time of the program Is included.

  The program information storage means 5 is constituted by a memory or the like, and stores the program information separated by the program information separation means 3a. The program information storage means 5 stores the stored program information based on the control from the main control means 9. This is output to the main control means 9. Note that the program information is stored as a broadcast schedule program guide, and this program information (broadcast schedule program guide) may be abbreviated as BRO (Broadcast table) table or simply BRO.

  The decoding means 7 decodes the digital TV signal (usually encoded) output from the program receiving means 3 and outputs it to the display device 2.

  The main control means 9 controls the digital broadcast receiving apparatus 1, and includes a selection pattern determining means 9a, a program recommendation level calculation increasing means 9b, a recommendation list display means 9c, a viewer interest level calculation means 9d, The field-of-interest genre coefficient correcting means 9e, the factor basic value correcting means 9f, the information life pattern table correcting means 9g, the viewing recommendation ranking added program table creating means 9h, and the table correcting means 9i are provided.

  The selection pattern determination unit 9 a determines the selection pattern stored in the selection pattern storage unit 13 based on the operation signal input from the operation unit 11. This selection pattern includes four patterns: a channel setting pattern, a program recommendation pattern, a program selection pattern, and a program search pattern.

  The channel setting pattern is a selection pattern in which a channel associated (set) with the viewing time (viewing time zone) when the viewer views the program is automatically selected. For example, when the power switch of the digital broadcast receiving device 1 is turned on (started up) at 8:00 (20:00) at night, the program of NHK general (ch1) is set to be displayed on the display device 2. When the power switch of the digital broadcast receiving apparatus 1 is turned on (started up) at 6:00 am, the program for NHK education (ch3) is set to be displayed on the display apparatus 2. .

  Also, this channel setting pattern can be set separately for holidays and holidays (holidays) and weekdays. For example, in the case of a holiday, NHK synthesis (ch1) programs are set to be displayed on the display device 2 from 20:00 to 21:00, and in the case of weekdays, the program is released from 20:00 to 21:00 (for example, ch8). Are set to be displayed on the display device 2.

  The recommended program pattern is a program that the apparatus 1 determines a program that is highly likely to be suitable for the viewer's way of spending in a certain time zone (at a certain time) from among the currently broadcast programs, and is recommended to be viewed. It is a selection pattern recommended to the viewer. This program recommended pattern is basically intended to make viewers feel relaxed at the time when viewers want to spend comfortably, and at the time when viewers want to get some information, news and weather forecasts. In the time zone, sports broadcasts, dramas and movies are recommended.

  The program selection pattern is a program that has been broadcast in the past based on the interest phrases included in the viewer's personal information (gender, age, occupation, hobby, etc., hereinafter referred to as viewer personal information). This is a selection pattern that selects programs that are likely to be viewed or watched from among programs that are being broadcast or programs that are broadcast in the near future (several hours later, today, within a week, etc.) . It is also possible for viewers to individually set arbitrary words as interest phrases.

  The program search pattern is a selection pattern in which a character string (including at least one registered word / phrase) in which the viewer is interested is designated in advance and a program related to this character string is searched. That is, the program search pattern searches for a program that matches the search word from the program table (EPG) generated by the program information (SI) using the registered lexical character contained in the character string as a search word (keyword). To do. This program search pattern most actively selects the program that the viewer wants to view.

  In addition, this program search pattern can be registered in advance as a search word by the viewer in the digital broadcast receiving apparatus 1. In this case, when the viewer turns on the power switch of the digital broadcast receiving apparatus 1 and selects a program search pattern, a message such as “Do you want to search by registered word?” On the display screen of the display apparatus 2. Even if a character string is not designated (registration tokens are not input one by one), a program search is immediately executed.

  By using this registered word, when searching for a program by a program search pattern, the number of key operations for the viewer to operate the operation means 11 can be reduced, and the program that the user wants to watch can be easily searched. In addition, once a registered word is registered, the digital broadcast receiving apparatus 1 informs the viewer about the program that matches the registered word (since it alerts the viewer), thus preventing oversight. Can do.

  When the program recommendation pattern is selected by the selection pattern determination unit 9a (when the program recommended by the device 1 is casually viewed), the program recommendation level calculation increasing unit 9b displays a program recommendation level indicating the recommended level of the program. While calculating, the registered lexical included in the interest lexical or character string included in the viewer's personal information is compared with the program name or program description included in the program information, and there is a match. When the program is being broadcast, the program recommendation level of the program is increased.

  The recommended list display unit 9c displays a recommended program list (recommended list), which is a list of programs whose program recommendation level has been increased by the program recommendation level calculation increasing unit 9b, on the display device 2 via the composition switching unit 10. To do. Then, the viewer can select a program by referring to the recommended program list (recommended list) displayed on the display device 2 even when viewing the program according to the recommended program pattern. become.

  That is, when the viewer selects a program recommendation pattern and passively views the program by the program recommendation level calculation increasing unit 9b and the recommendation list display unit 9c, the viewer's individual input by the viewer It is possible to prevent an oversight of a program including an interest word / phrase included in information or a registered word registered in advance.

  The viewer interest level calculation means 9d calculates the viewer interest level indicating the viewer's interest level by comparing the viewer personal information with the program information when selecting the program by the program selection pattern. . The viewer interest level is calculated by obtaining the inner product of the viewer personal information and the program information. That is, the audience interest level is the program classification genre classification interest coefficient (coefficient of the field of interest genre coefficient table) based on the classification of the viewing type in the viewer personal information, and the program included in the program information. This is the inner product with the genre division. The main control means 9 displays the program information of the selected program on the display device 2 when selecting the program by the program selection pattern based on the calculated audience interest level.

  That is, the higher the viewer interest level is, the faster the order in which the program information of the program selected by the program selection pattern is displayed on the display device 2 (higher ranking). Then, the main control means 9 displays the program information of programs with high viewer interest on the display device 2 in order from the top one, and when it cannot be displayed on one display screen of the display device 2, the next display In addition to displaying a next screen button for shifting to the screen, a presentation screen configuration for displaying a previous screen display button for returning to the original display screen is performed.

  As a result, the program to be viewed can be selected from the currently broadcast programs in the order corresponding to the viewer's interest.

  Also, the higher the viewer interest level is, the more detailed the program information of the program selected by the program selection pattern can be displayed. For example, when the viewer interest level is less than 20 points (100 points is the maximum), only the program name of the program is displayed on the display device 2, and when the viewer interest level is 80 points or more, the program is displayed. Are displayed on the display device 2.

  The field-of-interest genre coefficient correction means 9e determines (selects) that the viewer views the coefficient (program classification genre-classified interest coefficient) of the field-of-interest genre coefficient table stored in the field-of-interest genre coefficient table storage means 19. The program is corrected based on the program. That is, the interested field genre coefficient correcting means 9e corrects (increases) the coefficient (program classification genre classified interest coefficient) of the field to which the program decided to be viewed by the viewer belongs.

  In other words, when the viewer selects and decides the program, the interested field genre coefficient correcting means 9e evaluates the degree of matching between the selection decision result and the interested field genre coefficient table, and when the degree of matching is low, This is to correct the coefficient in the field of interest genre coefficient table.

  The field-of-interest genre coefficient table divides programs that are digitally broadcast into major categories and medium categories, and also has viewing-type numeric values that indicate what types of programs (in this case, eight categories) are shown. (Detailed examples will be described later). The major category is roughly classified into programs such as news, sports, information, and dramas. The middle category is such as scheduled, general, weather, featured documents, political parliament, etc. if the major category is news. The programs are classified based on the contents to be broadcast.

  By using the result of selecting the program that the viewer wants to view from the programs selected by the program selection pattern by the interested field genre coefficient correction means 9e, information on the interested field that the viewer is interested in (interest Field genre coefficient) is corrected, it is possible to obtain an interest field genre coefficient table more suitable for the interest (preference) of the viewer, and to realize program selection processing by a more accurate program selection pattern. .

  The factor basic value correcting means 9f uses the factor basic value in the factor basic value table stored in the factor basic value table storage means 21 as the program name included in the program information when the program recommended pattern is selected. Or a noun, a person name, or a place name in the program description. Note that the program name, noun, person name, and place name in the program description are stored in the factor correction dictionary stored in the factor correction dictionary storage means 25 (detailed examples will be described later).

  The factor basic value table classifies the program into factors (three factors of comfort, information, and excitement) that indicate the characteristics of the program, and assigns the factor basic value of each factor, with the total for each program as 100. (Detailed examples will be described later). For example, in the case of a news program, it is “Keraku 20”, “Information 60”, “Emotion 20”, and in the case of a variety program, it is “Keraku 50”, “Information 30”, “Emotion 20”. In the case of a romance drama, “Kairaku 30”, “Information 10”, “Emotion 60” are displayed.

  If the program name included in the program information, the noun, the name of the person in the program description, and the place name match those stored in the factor correction dictionary, the factor basic value correcting means 9f Correct the base value. In the factor correction dictionary, a factor correction value for correcting the factor basic value is associated with a noun, a person name, a place name, and the like.

  For example, if a factor basic value in the factor basic value table is “Karakaku 30”, “Information 20”, “Impression 50” and the program description of the program information includes Matsushima Nana ○ Is described in the factor correction dictionary as “Karagaku 3”, “Information 1”, “Emotion 5”, the factor basic value in the factor basic value table is “ It will be corrected to “Care 33”, “Information 21”, “Emotion 55”. Here, the factor correction value is simply added to the factor basic value. However, the factor correction value may be added to the factor basic value after being multiplied by a preset setting value.

  The information life pattern table correcting means 9g selects the information life pattern table stored in the information life pattern table storage means 23 from the recommended recommendation list when the program recommended pattern is selected. The program is corrected based on the program.

  The information life pattern table associates a factor basic value indicating a characteristic of a program with a time (time zone) according to a viewer's life pattern (detailed examples will be described later). The viewer's life pattern indicates a correlation between the viewer's actual life and the viewing of the program.

  For example, suppose that people who make up a family are watching the television of the family as the father of a company employee, the mother of a full-time housewife, and the son of a student. The people who make up the family watch TV (for example, news and weather forecasts) while having breakfast at almost regular times. After the meal, the father of the office worker goes to the company, and the son who is a student is a university student. Head for. The mother of a full-time housewife watches TV (for example, a rebroadcast drama) after breakfast. Then, after returning home, the son who is a student watches television (for example, variety) with the mother of a full-time housewife while having dinner. Furthermore, the father of the office worker returns home late at night and watches a television (for example, a sports program broadcasting professional baseball results) after returning home.

  In this way, the life time of each person making up the family is different, and how the program is being viewed varies depending on the time of day. So, in the life of the people who make up the family, what kind of mood you spend every time, and the TV viewing tendency you want to see at that time, the three factors of "comfort", "information", "impression" The information life pattern table shows whether any of these is emphasized.

  In this information life pattern table, television viewing tendency is set by setting values of three factors for each time zone. For example, in the case of a father who is a company employee and a son who is a student, the values of factors in the information life pattern table are often different between weekdays when going to the company or university and holidays when they do not go.

  In this information life pattern table, factors of comfort, information, and excitement are set every hour (or several hours), for example, when watching a sports program late at night on weekdays as illustrated. Each factor at the time is set as comfort 20, information 60, impression 20, and when watching a variety program at noon, each factor at 12:00 is set as comfort 70, information 20, impression 10.

  The information life pattern table correcting means 9g corrects the factors of the information life pattern table at the broadcast time (broadcast time zone) of the program according to the factors of the program that the viewer has decided to view.

  In other words, when the viewer selects and decides the program, the information life pattern table correcting means 9g evaluates the degree of coincidence between the result of this selection and decision and the information life pattern table. It modifies the factors of the life pattern table.

  Further, the information life pattern table correcting means 9g corrects the information life pattern table at a fixed time (for example, 3 hours before and after) before and after the broadcast time (broadcast time zone) of the program selected and determined by the viewer. The information (factor basic value) related to the information life pattern table is corrected. Thus, when the information (factor basic value) related to the information life pattern table of the viewer is corrected using the result of the viewer selecting and determining the program when the recommended program pattern is selected, once. (For example, 7 [a total of 7 factors: 1 factor basic value of the broadcast time of the program, 3 factor basic values of the previous 3 hours and 3 factor basic values of the next 3 hours]) The basic factor value may be corrected.

  Information related to the characteristics of the program that changes according to the time (time period) using the result of selecting the program that the viewer wants to view from the programs selected by the program selection pattern by the information life pattern table correcting means 9g ( (Three factors of comfort, information, and emotion) have been corrected, so it is possible to obtain an information life pattern table that is more suitable for the lifestyle pattern (life style) of the viewer, and program recommendation processing with a more accurate program recommendation pattern Can be realized.

  The viewing recommendation rank added program table creation means 9h recommends viewing to the viewer based on the degree of program recommendation or the degree of interest of the viewer when the program recommendation pattern or the program selection pattern is determined by the selection pattern determination means 9a. A viewing recommendation ranking additional program table (a personalized EPG arranged for individual viewers) is created by adding the viewing recommendation ranking, which is the ranking, to the program. In this viewing recommendation rank addition program table creating means 9h, for example, at 19:00, the viewing recommendation rank 1 is added to the drama of the broadcasting station A, and the viewing recommendation rank 2 is added to the variety program of the broadcasting station B. The viewing recommendation ranking added program table is created.

  In addition, the viewing recommendation ranking additional program table creating unit 9h holds the viewer for each broadcasting station stored in the broadcasting station correction value storage unit 27 when creating the viewing recommendation ranking additional program table. The viewer's interest level and the program recommendation level for the program are corrected by the broadcast station correction value obtained by digitizing the image. As a result, the viewing recommendation order is corrected.

  For example, when a love drama is being broadcast by broadcast station A and broadcast station B at around 21:00 (and there is no difference in viewer interest and program recommendation), broadcast station A When the broadcast station correction value 100 is set and the broadcast station B is set with the broadcast station correction value 75 for the drama, the drama of the broadcast station A has the first viewing recommendation rank. Also, when a news program is being broadcast by broadcast station A, broadcast station B, and broadcast station C at around 23:00 (and there is no difference in viewer interest and program recommendation), broadcast station A The broadcast station correction value 50 is set for the news program, the broadcast station B is set with the broadcast station correction value 100 for the news program, and the broadcast station C is set with the broadcast station correction value 75 for the news program. In this case, the news program of the broadcasting station B is ranked first in the viewing recommendation order.

  By this viewing recommendation rank addition program table creation means 9h, the viewer's preference regarding the broadcasting station can be directly reflected in the viewing recommendation rank addition program table, and program recommendation processing and program selection pattern in the program recommendation pattern Can improve the accuracy of the program selection process, and the broadcast program desired by the viewer can be selected accurately and immediately.

  When the program search pattern is determined by the selection pattern determining unit 9a, the table correcting unit 9i stores the interested field genre coefficient table stored in the interested field genre coefficient table storing unit 19 and the information life pattern table storing unit 23. At least one of the stored information life pattern table is corrected based on the program searched and determined by the program search pattern. That is, this table correction means 9i functions when the program search pattern is selected, and when the program selection pattern is selected, the interested field genre coefficient correction means 9e and the program recommended pattern are selected. It also has the function of the information life pattern table correcting means 9g.

  In the program search pattern in which the viewer actively searches for and selects a program by the table correction means 9i, the search result is used to correct the interest field genre coefficient table and the information life pattern table, thereby allowing the viewer to Thus, it is possible to obtain a more suitable field of interest genre coefficient table and information life pattern table, and it is possible to realize program recommendation processing based on an appropriate program recommendation pattern and program selection processing based on a program selection pattern.

The broadcast station correction value is output to the main control means 9. The broadcast station correction value table may be abbreviated as an SRF (Station Rating Factor) table. Further, referring to this broadcast station correction value table and increasing or decreasing the viewer interest level by the main control means 9 of the digital broadcast receiving apparatus 1 is called CH rating.

  The program information storage unit 5 and the storage units 13 to 27 are configured separately, but may be configured as one storage unit.

  According to this digital broadcast receiving apparatus 1, according to the viewing intention of the viewer, the program recommendation is performed by the selection pattern determining means 9a from the selection patterns consisting of the channel setting pattern, the program recommendation pattern, the program selection pattern, and the program search pattern. When the pattern is selected, the program recommendation level calculation increasing means 9b compares the viewer's personal information with the program information, and based on the comparison result, the program recommendation level for recommending viewing of the program is obtained. Even if the viewer is watching the program in a relatively passive manner, the program that matches the interest lexical contained in the viewer's personal information or the registered lexical set It is possible to recommend a program that the viewer would like to watch without overlooking, and as a result, the broadcast program desired by the viewer can be selected accurately and immediately. Door can be.

  Further, according to the digital broadcast receiving apparatus 1, the channel setting pattern stored in the selection pattern storage means 13 is set separately for holidays, holidays, and weekdays, so that holidays, holidays, weekdays, Therefore, it is possible to deal with a case where the organization of the program broadcast from the broadcasting station is greatly different, and the broadcast program desired by the viewer can be selected accurately and immediately.

  Further, according to the digital broadcast receiving apparatus 1, program information related to programs selected by the program selection pattern is displayed on the display device 2 based on the viewer interest level calculated by the viewer interest level calculation unit 9d. Therefore, the broadcast program desired by the viewer can be selected accurately and immediately.

  Further, according to the digital broadcast receiving apparatus 1, when the program selection pattern is determined by the selection pattern determination means 9a, if the viewer determines to view the program selected by the program selection pattern, the genre of interest field The field of interest in which the program is classified in the field of interest genre table stored in the coefficient table storage means 19 is corrected, and the program selected by the program selection pattern when the viewer views the program next time. Since it is reflected, the broadcast program desired by the viewer can be selected accurately and immediately.

  Further, according to the digital broadcast receiving apparatus 1, a program recommended pattern is determined by the selection pattern determining means 9a, and a factor basic value table is used when obtaining a program recommendation level of a program recommended by the program recommended pattern. Since the factor basic value indicating the characteristics of the program stored in the storage means 21 is modified by the program name, the noun, the person name, and the place name included in the program information, for example, the same factor is given. Even if it is a program, the factor base value increases depending on the performer (the name of the performer), and as a result, the program recommendation level also increases, and the program that viewers would like to watch may be recommended. The broadcast program desired by the viewer can be selected accurately and immediately.

  Further, according to the digital broadcast receiving apparatus 1, when the program recommended pattern is determined by the selection pattern determining means 9a, when the viewer selects a program in the recommended list recommended by the program recommended pattern, the selected program is selected. The degree of coincidence between the factor basic value and the factor basic value in the information life pattern table stored in the information life pattern table storage means 23 is obtained. The trend, what factor of the program to watch) can be predicted, and as a result, the broadcast program desired by the viewer can be selected accurately and immediately.

  Further, according to the digital broadcast receiving apparatus 1, when a program recommended pattern is determined by the selection pattern determining means 9a, when a viewer selects a program recommended by the program recommended pattern, before and after the broadcast time of the program. Thus, the basic value of the factor over a certain period of time is corrected, so that it is possible to predict how the viewer spends in a wider range of time, and thus the preference of the program, and as a result, the broadcast program desired by the viewer can be accurately determined. And can be selected immediately.

  In addition, according to the digital broadcast receiving apparatus 1, the viewing recommendation rank addition program table creation means 9h creates a viewing recommendation rank addition program table, which is a personalized program table to which the viewing recommendation rank is added. By correcting the image of the broadcasting station held by the viewer stored in the value storage means 27 with the broadcasting station correction value, the viewing recommendation ranking additional program table more suitable for the viewer's preference can be obtained. The broadcast program desired by the viewer can be accurately and immediately selected.

  In addition, according to the digital broadcast receiving apparatus 1, when a program search pattern is determined by the selection pattern determining means 9a, a registered word is searched in advance when searching for a program to be viewed with the program search pattern. By registering and using this registered word as a search word, the viewer can select a desired broadcast program accurately and immediately without taking time and effort.

  Further, according to the digital broadcast receiving apparatus 1, when the program search pattern is determined by the selection pattern determination unit 9a, the interested field genre coefficient table storage unit 19 stores the program searched by the program search pattern. Since at least one of the stored field-of-interest genre coefficient table and the information life pattern table stored in the information life pattern table storage means 23 is corrected, the program recommended pattern will be displayed next time the viewer views the program. Therefore, the broadcast program desired by the viewer can be selected accurately and immediately.

  Thus, the operation of the digital broadcast receiving apparatus 1 will be described in more detail and more specifically.

<Transition of program selection method in digital broadcast receiver>
Next, transition of the program selection method in the digital broadcast receiving apparatus 1 will be described with reference to FIG. 2 (see FIG. 1 as appropriate). FIG. 2 is a diagram for explaining the transition of the program selection method (selection pattern).

  As shown in FIG. 2, when the digital broadcast receiving apparatus 1 is turned on (when the power switch is turned on), the (0) CH setting (channel setting pattern) is set to the default (initial value), and then (1) Program selection (program recommendation pattern) to (2) Program selection (program selection pattern) or (3) Program search (program search pattern) .

  The digital broadcast receiving apparatus 1 can be switched to any one of (1), (2), and (3) when the power is turned on, depending on the setting of the viewer.

<Operation of digital broadcast receiver including viewer operation>
Next, an operation when the viewer operates the digital broadcast receiving apparatus 1 will be described with reference to the flowchart shown in FIG. 3 (see FIG. 1 as appropriate).
When the viewer operates the digital broadcast receiving apparatus 1, the program selection method (selection pattern) includes specific CH (channel setting pattern), program recommendation (program recommendation pattern), program selection (program selection pattern, personalized EPG), and There are four methods (four) of program search (program search pattern).

  First, when the viewer turns on the power switch of the digital broadcast receiving device 1 (TV on, step S1), the digital broadcast receiving device 1 sets the viewer's personal identification (for example, presets for the viewer). After having entered the viewer's exclusive access code and collating the viewer identifier (user number ID [UID]), the current time is stored in the time zone channel table storage means 17. In the time zone channel table, it is determined whether or not the time zone is set for the specific channel (step S2).

  When it is determined that the current time is the time zone in which the specific channel is set (step S2, Yes), the digital broadcast receiving device 1 displays the specific channel set in advance by the viewer on the display device 2 (step S3). ) The viewer views the program displayed on the display device 2 (step S4). In step S2, if it is not determined that the current time is the time zone in which the specific channel is set (step S2, No), the digital broadcast receiving device 1 causes the display device 2 to display a program viewing method (selection pattern). A “first screen” prompting selection is displayed (step S5).

  Then, the digital broadcast receiving apparatus 1 performs a time-out process, and it is assumed that a program recommended pattern is selected if the viewer does not operate the apparatus 1 within a predetermined time (for example, 10 seconds) (step S6). ) The viewer views a program recommended by the program recommendation pattern (step S4). In addition, when the recommended list is displayed on the display device 2 within a predetermined time (the registered lexical in the interest lexical or character string included in the viewer personal information matches the program information of the currently broadcast program) The viewer selects a program from the recommended list (step S7), and views the selected program (step S4).

  In step S5, when the “first screen” prompting selection of a program viewing method (selection pattern) is displayed on the display device 2, the viewer selects “program selection” (program selection pattern) ( In step S8), the digital broadcast receiving apparatus 1 creates a personalized EPG (viewing recommendation rank-added program table) by the viewing recommendation rank-added program table creation means 9h and displays it on the display device 2 (step S9). The viewer refers to the personalized EPG (viewing recommendation ranking added program table), selects a program (step S10), and views the selected program (step S4).

  In step S5, when the “first screen” prompting the user to select a program viewing method (selection pattern) is displayed on the display device 2, the viewer selects “program search” (program search pattern) ( In step S11), the digital broadcast receiving apparatus 1 uses the display device 2 to inform the viewer of the program search procedure (step S12), and the viewer uses the registered lexical phrase as a search word to perform digital broadcast. The receiving apparatus 1 is made to search for a desired program. Then, the viewer selects a program to be viewed from the searched programs (step S13), and views the selected program (step S13).

<Operation of digital broadcast receiver>
Next, the overall operation of the digital broadcast receiving apparatus 1 and the operation in each selection pattern will be described with reference to the flowcharts shown in FIGS. 4 to 9 (see FIG. 1 as appropriate).
Note that the flowchart shown in FIG. 4 explains the overall operation of the digital broadcast receiving apparatus, and the flowchart shown in FIG. 5 explains the operations performed after the viewer selects a channel setting pattern. It is a thing. Further, the flowchart shown in FIG. 6 explains the operation performed after the viewer selects a program recommended pattern. The flowchart shown in FIG. 7 shows that the viewer selects a program selection pattern. FIG. 8 and FIG. 9 are flowcharts for explaining the operations performed after the viewer selects a program search pattern. .

<Overall operation of digital broadcast receiver>
The overall operation of the digital broadcast receiving apparatus 1 shown in the flowchart of FIG. 4 will be described.
First, the digital broadcast receiving apparatus 1 determines whether or not the current time when the power is turned on is a time zone in which a specific channel is set (different depending on holidays, holidays, and weekdays, and also depending on the day of the week) (step S21). ), When it is determined that the current time is the time zone in which the specific channel is set (step S21, Yes), the channel of the program received by the program receiving means 3 is the specific channel (viewing by channel setting pattern). (Step S22), and the program of the specific channel is presented on the display device 2 (Step S23).

  If it is not determined in step S21 that the current time is the time zone in which the specific channel is set (step S21, No), the digital broadcast receiving device 1 transitions to a program selection method based on a program recommended pattern. If the program including the interest lexical or registered lexical included in the viewer personal information or the character string is included in the currently broadcast program by the program recommendation level calculation increasing means 9b, The program recommendation level is increased, and a recommendation rank (rank in the recommendation list) is obtained (step S24).

  Then, the digital broadcast receiving apparatus 1 prompts the viewer to select a program viewing method, and displays the “first screen” including the recommended list on the display apparatus 2 by the recommended list display unit 9c (step S25). . The digital broadcast receiving apparatus 1 performs a timeout process, determines whether or not a predetermined time has been exceeded (Timeout?) (Step S26), and if the viewer does not operate the apparatus 1 within the predetermined time. When the time expires (step S26, Yes), timeout processing (timeout processing) is executed, and a program recommended pattern is selected (step S27), the viewer recommends a program recommended by the program recommended pattern (recommended program 1 Is viewed (step S23).

  Also, until the time expires in step S26, the cursor is moved to the indicated position displayed on the display device 2, such as a key reading from the operation unit 11 (such as pressing an operation button (not shown) of the operation unit 11). In addition, the digital broadcast receiving apparatus 1 determines whether or not there has been a “determine” operation button (step S28). The digital broadcast receiving apparatus 1 returns to step S26 when it is not determined that there is a key reading (step S28, No), and returns to step S26 when it is determined that there is a key reading (step S28, Yes). It is determined whether or not the reading is related to the recommended program pattern (step S29), and when it is determined that the key reading is related to the recommended program pattern (step S29, Yes), the recommended list display means 9c As the recommended list, 2 to 7 recommended programs are displayed on the display device 2 (step S30).

  Then, the digital broadcast receiving apparatus 1 uses the program recommendation degree calculation increasing means 9 and the recommendation list display means 9c to perform personalization recommendation that is a program recommendation pattern suitable for the individual viewer (step S31), and the viewer recommends it. A program selected from the listed programs is viewed (step S23).

  If it is not determined in step S29 that the key reading is related to the recommended program pattern (No in step S29), the digital broadcast receiving apparatus 1 determines whether the key reading is related to the program selection pattern. Is determined (step S32). If it is determined that the key reading is related to the program selection pattern (step S32, Yes), the digital broadcast receiving apparatus 1 obtains the interest ranking (viewer interest ranking) by the viewer interest level calculation means 9d ( Step S33).

  Then, the digital broadcast receiving apparatus 1 displays a “selection screen” on which the viewer selects a program to be viewed based on the interest ranking on the display device 2 (step S34), and determines whether or not there has been a key reading (step S34). Step S35). The process waits until it is determined that the key reading has been made (No in step S35). If it is determined that the key reading has been made (step S35, Yes), it is determined whether the program to be viewed has been determined by the key reading. (Step S36). If it is determined in step S36 that the program to be viewed has not been determined by key reading (No in step S36), the key reading indicates “next screen” and “previous screen” (step S36). S37), the process returns to step S34.

  When it is determined that the program to be viewed has been determined by key reading (step S36, Yes), the digital broadcast receiving device 1 uses the P-EPG (viewing recommendation ranking additional program created by the viewing recommendation ranking additional program table creation means 9h. Table) is displayed on the display device 2, and the viewer determines the program to be viewed (step S38). That is, the digital broadcast receiving apparatus 1 performs personalized selection which is a program selection pattern suitable for the individual viewer by the viewer interest level calculating unit 9d and the viewing recommendation rank added program table creating unit 9h (step S39). The viewer views a program selected from the selected programs (step S23).

  If it is determined in step S32 that the key reading is not related to the program selection pattern (No in step S32), the digital broadcast receiving apparatus 1 assumes that the program search pattern has been selected by the selection pattern determining unit 9a. Then, the viewer is prompted to input search word candidates (step S40).

  Then, the digital broadcast receiving apparatus 1 displays a “selection screen” selected by the viewer on the display device 2 by listing programs that match the search word (step S41), and determines whether or not there has been a key reading (step S41). Step S42). The process waits until it is determined that there is a key reading (No in step S42). If it is determined that there is a key reading (Yes in step S42), it is determined whether the program to be viewed is determined by the key reading. (Step S43). If it is not determined in step S43 that the program to be viewed has been determined by key reading (step S43, No), the key reading indicates “search transition” (step S44). The process returns to step S41.

  If it is determined that the program to be viewed has been determined by key reading (step S43, Yes), the digital broadcast receiving apparatus 1 determines selection or reservation of a program based on the program search pattern (step S45). Then, the digital broadcast receiving apparatus 1 performs a personalized search that is a program search pattern suitable for an individual viewer by searching for program information using a search word (step S46), and the viewer is searched. A program selected from the selected programs is viewed (step S23).

<Operation in channel setting pattern>
Next, the operation in the channel setting pattern will be described with reference to the flowchart shown in FIG. 5 (see FIG. 1 as appropriate).
First, the digital broadcast receiving apparatus 1 uses the main control means 9 to specify the viewer (viewer's personal identification, for example, an access code dedicated to each viewer preset for the viewer using the operation means 11. And the viewer identifier (checked with the user number ID [UID]) is performed (step S51). That is, the main control means 9 reads out the UID (viewer identifier, user number ID) included in the PF (viewer personal information) from the viewer personal information storage means 15 and accesses entered by the operation means 11. Check if it is correctly associated with the code. The viewer may be specified by detecting the fingerprint of the viewer, voiceprint recognition, retinal scanning, etc., in addition to the input of the access code by the operation means 11.

  Subsequently, the digital broadcast receiving apparatus 1 determines what day of the week (DOW: Day Of Week) or weekday (WD: WeekDay) the power of the apparatus 1 is turned on, based on a calendar used by a timing unit (not shown). It is checked whether it is a holiday (HD: HoliDay) and at what time and what time is the current time (step S52).

  Then, the digital broadcast receiver 1 checks the time zone channel table (TZi-Chi table) stored in the time zone channel table storage unit 17 by the main control unit 9 (step S53), and the current day of the week and the current time are determined. It is determined whether or not the time zone in the time zone channel table is applicable (step S54). When it is determined that the current day of the week and the current time correspond to the time zone in the time zone channel table (step S54, Yes), the digital broadcast receiving device 1 displays a program based on the channel setting pattern on the display device 2, and If it is not determined that the day of the week and the current time correspond to the time zone in the time zone channel table (step S54, No), the process proceeds to the next process (NEXT, program recommended pattern).

<Operation in recommended program pattern>
Next, the operation in the recommended program pattern will be described with reference to the flowcharts shown in FIGS. 6A and 6B (see FIG. 1 as appropriate).
In the digital broadcast receiving apparatus 1, the main control means 9 inputs the viewer identification (viewer personal identification, for example, an access code dedicated to each viewer preset for the viewer by the operation means 11. The viewer identifier (user number ID [UID]) is checked) (step S61). Subsequently, the digital broadcast receiving apparatus 1 checks the day of the week when the apparatus 1 is turned on, a weekday or a holiday from the calendar used by the time measuring means (not shown), and the current time is what hour and how many minutes. Is set by checking (step S62).

  Then, the digital broadcast receiving apparatus 1 uses the main control means 9 to store the information life pattern table (ILP) stored in the information life pattern table storage means 23 and the interest stored in the field of interest genre coefficient table storage means 19. Referring to the field genre coefficient table (J3F) (step S63), the recommended order is determined by determining the degree to which the broadcast program corresponds to the information life pattern table. Here, the program with the highest recommended order is recommended to the viewer, and some of the programs with the next recommended order are displayed as candidates (recommended list) on the display device 2 so that the viewer can select them. Is possible.

  Here, the digital broadcast receiving device 1 stores the recommended order in the program information storage unit 5 within the allowable waiting time (AWT: Allow Wait Time) range (step S64) set by the viewer. Based on the factor correction dictionary (REV) stored in the factor correction dictionary storage means 25 for all programs included in the program information (broadcast schedule program guide, BRO), the program genre specification and the factor basic value ( x1: comfort, x2: information, x3: impression) are obtained (step S65). When a plurality of genres are specified for one program, the arithmetic average of these is set as a factor basic value (x1 to x3).

  That is, the digital broadcast receiving apparatus 1 stores the program name included in the program information of the program and the name, place name, and noun in the program description in the factor correction dictionary storage unit 25 by the factor basic value correction unit 9f. If it is included in the factor correction dictionary, the factor correction value described in the factor correction dictionary is multiplied by a preset setting value and added to the factor basic value to obtain the three factor values (x′1 to x) of the program. '3) is obtained.

  If the program name and program description included in the program information of the program contain multiple names, place names, and nouns, the square root of the sum of squares is obtained from each of the factor correction values. Let the square root of the sum of squares be a new factor correction value. Here, assuming that the three factor values (x′1 to x′3) are xi ′, the factor basic value is xi, the factor correction value is dxi, and the set value is Sri, xi ′ = xi + dxi * Sri. Equation (1) is obtained.

  Then, the digital broadcast receiving apparatus 1 recommends a program by the main control means 9 by weighting with the factor basic value (factor coefficient) of the information life pattern table stored in the information life pattern table storage means 23. The program recommendation degree indicating is calculated. Here, when the program recommendation level is z and the factor basic values (factor coefficients) in the information life pattern table are y1 to y3, z = y1 * x1 ′ + y2 * x2 ′ + y3 * x3 ′ (2) It becomes. The recommended order (primary) of the program is determined by the program recommendation level z (step S66).

  Next, the digital broadcast receiving apparatus 1 refers to the broadcast station correction value table stored in the broadcast station correction value table storage unit 27 by the main control unit 9 and increases or decreases the viewer interest level. Is executed (step S67).

  In addition, the digital broadcast receiving apparatus 1 is included in an interest lexical (IWi (i-th Interest Word)) included in the viewer personal information referred to in the program selection pattern or a character string referred to in the program search pattern. When the registered lexical phrase (RWi (i-th Reference Word)) matches the program name and program description included in the program information, the program recommendation level calculation increasing means 9b The program recommendation level is increased, the recommendation order is corrected (step S68), the final program recommendation degree is determined, and the program recommendation order (final) is determined (step S69).

In this embodiment, the digital broadcast receiving apparatus 1 calculates the program recommendation z by the inner product of x (factor basic value) and y (factor coefficient). An equation for calculating the program recommendation degree z by this inner product is shown in Equation (3).
z = y1 * x1 ′ + y2 * x2 ′ + y3 * x3 ′ (3)

As another determination method, the program recommendation degree z may be obtained by the following formula (4) as the Manhattan distance. High program recommendation z may be obtained by minimizing y1 to y3 and x1 'to x3' in the equation (4).
z = (y1-x1 ') + (y2-x2') + (y3-x3 ') Equation (4)

  In addition, when a program to be viewed is selected from the recommended list in the recommended program pattern, the program recommended pattern in the digital broadcast receiving apparatus 1 is personalized based on the result of the viewer selecting the program, that is, the viewing history. (Revise the information life pattern table according to the viewer). The operation of personalizing the recommended program pattern will be described with reference to the flowchart shown in FIG.

  First, when the viewer determines a program from a recommended recommendation list and views it in the recommended program list in the program recommendation pattern (step S71), the recommended order Rp of the determined program (determined program) is determined in advance. It is determined whether it is lower than a set threshold value Rn (for example, 6) (step S72). When it is determined that the recommended ranking Rp is lower than the preset threshold value Rn (Yes in step S72), the digital broadcast receiving device 1 has a recommended ranking Rp of the determined program that is higher in the recommended list (fifth or higher). If so, the personalization of the recommended program pattern ends.

  Further, the digital broadcast receiving apparatus 1 determines that the recommended rank Rp is not lower than the preset threshold value Rn (step S72, No), that is, the recommended rank Rp of the decided program is low in the recommended list (sixth rank). In the case of the following), the three factor basic values (three factor coefficients) of the determined program are examined (step S73) (here, EIT (Event Information Table) Present) and the determination in the information life pattern table (ILP). Three factor basic values (three factor coefficients) at the time (time zone) when the program was broadcast are corrected by the following procedure (step S74).

(xi / (x1 + x2 + x3) −yi) where xi is the three factor basic values of the determined program, yi is the three factor coefficients of the time zone in which the determined program is broadcast, si is the correction threshold, and ci is the correction unit. / (Y1 + y2 + y3)) ** 2 (this meaning means square)> si ** 2... Formula (5), the information life pattern table is corrected according to the following formula (6).
When xi / (x1 + x2 + x3) −yi / (y1 + y2 + y3)> 0,
yi = yi + ci
When xi / (x1 + x2 + x3) −yi / (y1 + y2 + y3) <0,
yi = yi−ci (6)

  As described above, the digital broadcast receiving apparatus 1 sees (calculates) the difference (difference) between the recommended program recommended by the recommended list and the determined program selected and determined. Then, when selecting and viewing a program according to the recommended program pattern, at the start of the program, three factor coefficients (three hours in this case) before and after the corresponding time zone in the information life pattern table, Correct according to equation (7).

  When the recommended rank Rp of the determined program is equal to or higher than a preset threshold value Rn, the digital broadcast receiving apparatus 1 broadcasts the determined program according to the three factor basic values (here, xi ′) of the determined program. Factor coefficient yij (yi0) of the current time zone (start time zone) and factor coefficients yij (yi (-3), yi (-2), yi (-1), yi1, yi2, yi3) Modify about.

  That is, here, i represents the time when the decided program was broadcast (if i = 1, 1 o'clock, if i = 16, 16:00), and j is 0, the start of the decided program broadcast being started This is a time zone. Based on this start time zone, j = -3 is 3 hours ago, j = -2 is 2 hours ago, j = -1 is 1 hour ago, j = 1 is 1. After time, j = 2 represents 2 hours later, and j = 3 represents 3 hours later.

Then, if the modified factor coefficient is a new yij, ci is a correction unit, and fj is a correction filter constant,
New yij = yij + ci · fj (xi′−yij) / 2000 (7)
It becomes. The expression (7) will be described in detail. Yij is a value in a three-hour range (normalized by 100) before and after the corresponding time zone of the information life pattern table (ILP table) shown in FIG. The correction unit is set to a value of ˜20, and fj is 6 (f (−3), f3), 26 (f (−2), f2), 69 (f (−1), f1), 100 (f0). This is a modified filter constant with a value of (I don't understand this. Please tell me.) Xi ′ is a basic value of three factors of a determined program. When a plurality of genres are designated, an arithmetic average of those values is a value of x1 to x3 (factory basic values of comfort, information, and emotion). It is obtained by normalizing from

In this way, the digital broadcast receiving apparatus 1 has not only the time (time zone) at which the determined program is broadcast, but also, for example, three hours before and after the time zone range (time range) for correcting the information life pattern table. It is also possible to target a wide range.
Furthermore, even when the program recommendation pattern is selected, the digital broadcast receiving device 1 is within the time frame in which the program is viewed according to the program recommendation pattern when the search word in the program search pattern is registered ( If a program matching the search term is broadcast within the recommended time frame), for example, the program is introduced at the bottom of the recommended list. If there are a plurality of programs that match the search term, the programs are introduced from the lowest order.

<Operation in program selection pattern>
Next, the operation in the program selection pattern will be described with reference to the flowcharts shown in FIGS. 7A and 7B (see FIG. 1 as appropriate).
In the digital broadcast receiving apparatus 1, the main control means 9 inputs the viewer identification (viewer personal identification, for example, an access code dedicated to each viewer preset for the viewer by the operation means 11. The viewer identifier (user number ID [UID]) is checked) (step S81). Subsequently, the digital broadcast receiving apparatus 1 checks the day of the week when the apparatus 1 is turned on, a weekday or a holiday from the calendar used by the time measuring means (not shown), and the current time is what hour and how many minutes. Is set by checking (step S82).

  Then, the digital broadcast receiving apparatus 1 converts the viewer personal information stored in the viewer personal information storage unit 15 by the main control unit 9 at the screening time (STR of the screening time) when the program selection pattern is determined. The degree of coincidence in which the program weighted by the interest phrase included and the field-of-interest genre coefficient table IJF stored in the field-of-interest genre coefficient table storage unit 19 matches the viewer's interest is obtained (step S83).

  The initial value of the value (interest field genre coefficient) v (J) corresponding to each genre in the field of interest genre coefficient table is document 1 (Hara, Tomonori, Shigemori, “TV viewing type and station image”, NHK broadcasting. It is set according to the eight viewing types (laughing stimulation, enthusiasm trend, romantic fiction, breath zapping, easy relaxation, healthy practical use, news culture, and relations) described in the Annual Survey of Culture Research No. 45, Dec. 2000) ing. When a plurality of genres are designated for a program, the arithmetic average Σv (J) of v (J) is set as a value (field of interest genre coefficient).

  Here, the digital broadcast receiving apparatus 1 obtains the interest ranking within the range of the allowable waiting time (AWT) and the remaining time set by the viewer (step S84). The digital broadcast receiving apparatus 1 stores the interest word / phrase included in the viewer personal information stored in the viewer personal information storage unit 15 and the program information storage unit 5 by the viewer interest level calculation unit 9 d. The viewer's interest level (interest ranking) is determined based on the program information that has been set (step S85).

  That is, the degree of interest in viewing matches (matches) the program name included in the program information and the name, place name, and noun of the program description with the interest lexical IWi included in the viewer personal information set by the viewer. And the number w of matching words is obtained. The degree to which the program (program content) is close to the viewer's interest from both the genre coefficient of interest and the viewer's personal information is obtained by the following formula (8).

Degree of program content close to viewer's interest m '= v (J) + Sw * w ** 0.5
Sw is a preset constant (8)

  The interest level of the program is determined in descending order of the value indicating the degree m ′ of the program content close to the viewer's interest. That is, the reason why the order of interest is determined in descending order of m ′ is that this degree m ′ indicates the possibility that the program has a high degree of viewer interest, including matters of interest to the viewer. Then, the digital broadcast receiving apparatus 1 refers to the broadcast station correction value table stored in the broadcast station correction value table storage means 27 by the main control means 9, and sets the CH rating that increases or decreases the audience interest level. Execute (step S86).

  The digital broadcast receiving apparatus 1 corrects the interest ranking by the main control means 9 when the registered word used in the program search pattern matches the program name and the program description included in the program information. (Step S87) The final audience interest level is determined, and the interest ranking (final) of the program is determined (Step S88). When determining the interest ranking (final), if there are programs with the same ranking (the viewer interest level is the same), the viewing recommendation ranking is higher in the remaining broadcast time. Then, the digital broadcast receiving apparatus 1 creates a viewing recommendation ranking added program table based on the viewing recommendation ranking by the viewing recommendation ranking addition program table creation unit 9h.

  In the program selection pattern, when the viewer selects a program to be viewed from the viewing recommendation rank-added program table created by the viewing recommendation rank-added program table creation unit 9h, the result of the viewer selecting the program That is, based on the viewing history, the program selection pattern in the digital broadcast receiving apparatus 1 is personalized (the field of interest genre coefficient table is modified in accordance with the viewer). The operation of personalizing the program selection pattern will be described with reference to the flowchart shown in FIG.

  First, in the program selection pattern, the digital broadcast receiving apparatus 1 determines the viewing recommendation rank Ip of the decided program (determined program) when the viewer decides and views the program from the viewing recommendation rank added program table (step S91). Is lower than a preset threshold value In (step S92). When it is determined that the viewing recommendation order Ip is lower than the preset threshold value In (step S92, Yes), the digital broadcast receiving device 1 has the viewing recommendation order Ip of the determined program having a higher rank in the viewing recommendation order additional program table. In the case of, personalization of the program selection pattern ends.

  Further, the digital broadcast receiving apparatus 1 determines that the viewing recommendation rank Ip is not lower than the preset threshold value In (step S92, No), that is, the viewing recommendation rank Ip of the determined program is the viewing recommendation rank additional program table. In the case of low rank, the genre of the determined program is checked (step S93) (here, EIT (Event Information Table) (Present)), and the genre coefficient of interest of the determined program in the interest genre coefficient table (IJF) is as follows. (Step S94).

  In the field-of-interest genre coefficient table, the correction value cv is added to the value of the field-of-interest genre coefficient v (J) of the determined program genre Jv, and the sum of the field-of-interest genre coefficients of the entire audience type is divided by 1000 + cv to obtain v ( Normalize the value of J). When a plurality of (for example, n) genres Jv are designated in the determined program, cv / n is added to the value of each field of interest genre coefficient v (J) for correction.

<Operation in program search pattern>
Next, operations in the program search pattern will be described with reference to the flowcharts shown in FIGS. 8 and 9 (see FIG. 1 as appropriate). First, the operation from program search to search result display will be described with reference to the flowchart shown in FIG.
In the digital broadcast receiving apparatus 1, the main control means 9 inputs the viewer identification (viewer personal identification, for example, an access code dedicated to each viewer preset for the viewer by the operation means 11. And verifying the viewer identifier (user number ID [UID])) (step S101).

  Subsequently, the digital broadcast receiving apparatus 1 causes the main control means 9 to display on the display apparatus 2 to instruct the search method in the program search pattern (step S102). The search method includes the genre of the program scheduled to be broadcast by the viewer (nouns and place names included in the genre division), the program name included in the program information, the names of people in the program description, place names, and nouns (general nouns). One of a method to be used (step S103) and a method of using an interest word / phrase included in the viewer's personal information or a registered word registered in advance (step S104), and a genre, a person name, a place name, a noun (general noun) A program search using (step S105) or a program search using similar words and registered words (similar word search) (step S106).

  Here, when step S105 and step S106 are executed, the time range for searching for the program can be set to 3 days / 1 week (RDR [Retrieve Date Range]). Then, the digital broadcast receiving apparatus 1 includes the program names of all programs included in the program information within the allowable waiting time range set by the viewer by the main control means 9 and within the set time range. The program description is searched, and the matched program is obtained.

  Then, the digital broadcast receiving device 1 displays the display result on the display device 2 by the main control means 9 (step S107). When a plurality of programs are obtained as a result of the program search, they are displayed on the display device 2 in ascending order from the earliest scheduled broadcast time. Further, when the display related to the searched program does not fit on one display screen of the display device 2, it is performed over a plurality of screens.

  Further, based on the result of the viewer selecting the searched program, that is, the viewing history, the program search pattern in the digital broadcast receiving device 1 is personalized (the genre coefficient table of interest field and the information life pattern table are corrected according to the viewer). )I do. The operation of personalizing the program search pattern will be described with reference to the flowcharts shown in FIGS. FIG. 8B shows the operation when the personalization of the program search pattern is simplified. FIG. 9 shows an operation in the case where the program search pattern personalization is performed based on the recommended ranking and the interest ranking of the determined program selected and determined from the searched programs, similarly to the personalization of the program recommendation pattern and the program selection pattern. .

With reference to the flowchart shown in FIG. 8B, the operation when the personalization of the program search pattern is simplified will be described.
First, when the viewer is watching the program searched by the program search pattern, the digital broadcast receiving apparatus 1 checks the genre of the program being viewed (step S111), and based on the genre of the program being viewed. Then, the table correction means 9i corrects the field of interest data (field of interest genre coefficient) and the three factor basic values (three factor coefficients) of the information life pattern (step S112).

With reference to the flowchart shown in FIG. 9, the operation in the case where the personalization of the program search pattern is performed based on the recommended rank and the interest rank of the determined program selected and determined from the searched program will be described.
The digital broadcast receiving apparatus 1 obtains the recommended order of the program (step S121), displays the recommended list on the display device 2, and examines the recommended order Rp of the determined program that the viewer has decided to view (step S122). . Subsequently, the digital broadcast receiving apparatus 1 determines whether or not the recommended order Rp of the determined program is lower than a preset threshold value Rn (for example, 6) (step S123). When it is determined that the recommended rank Rp is lower than the preset threshold value Rn (step S123, Yes), the digital broadcast receiving device 1 has a recommended rank Rp of the determined program having a high rank (5th or higher) in the recommended list. If so, the process proceeds to step S126.

  Further, the digital broadcast receiving apparatus 1 determines that the recommended rank Rp is not lower than the preset threshold Rn (No in step S123), that is, the recommended rank Rp of the determined program is low (6th rank) in the recommended list. In the case of the following), the three factor basic values (three factor coefficients) of the determined program are checked (step S124), and the three factors of the time (time zone) at which the determined program was broadcast in the information life pattern table The basic value (three factor coefficients) is corrected by the following procedure (step S125).

  Then, the digital broadcast receiving apparatus 1 obtains the interest ranking of the viewer (step S126), displays the viewing recommendation ranking added program table on the display device 2, and the interest ranking of the determined program that the viewer has decided to view. (Viewing recommendation order) Ip is examined (step S127). Subsequently, the digital broadcast receiving apparatus 1 determines whether the interest ranking (viewing recommendation ranking) Ip of the determined program is lower than a preset threshold value In (step S128). The digital broadcast receiving apparatus 1 determines that the interest ranking (viewing recommendation ranking) Ip is lower than the preset threshold value In (step S128, Yes), that is, the interest ranking (viewing recommendation ranking) Ip of the determined program is viewed. If the ranking is higher in the recommended ranking added program table, the personalization of the program search pattern is terminated.

  Further, the digital broadcast receiving apparatus 1 does not determine that the interest ranking (viewing recommendation ranking) Ip is lower than the preset threshold value In (No in step S128), that is, the interest ranking of the determined program (viewing recommendation ranking). If Ip is low in the viewing recommendation ranking additional program table, the genre of the determined program is checked (step S129), and the interest data (interest field genre coefficient) of the determined program in the field of interest genre coefficient table is corrected (step S130). .
