  The operation of the content guidance service system 100 configured as described above will be described.

  First, the program registration operation will be described. The program management server 110 in the program production company 100 is attribute data such as program data of a broadcast program as content and a program code for identifying the broadcast program for the program distribution system 210 in the broadcast station 200. Send SI data. The program distribution system 210 in each broadcast station 200 holds the received SI data and transmits it to the SI collection / delivery server 310 in the all-station SI collection / delivery center 300.

  The SI collection / delivery server 310 in the all-station SI collection / delivery center 300 receives SI data from each broadcasting station 200, registers it in the program information DB 320, and transmits it to the information management server 510 in the service center 500 via the communication network 700. To do.

  The information management server 510 in the service center 500 registers the received SI data in the information management DB 520 as program related data. An example of the program related data is shown in FIG. The program-related data shown in FIG. 4 includes a management ID, a broadcast station ID for identifying the broadcast station 200 that is the transmission source of the broadcast program, a program code, the broadcast date, start time, and end of the broadcast program. It consists of a time, a name of the broadcast program (program name), a genre of the broadcast program, and keywords as characteristic items characterizing the broadcast program such as contents and performers.

  In addition, the information management server 510 registers communication-related content related data, which is data related to communication-related content other than broadcast programs, in the information management DB 520. An example of communication system related data is shown in FIG. The communication system content related data shown in FIG. 5 includes a management ID, a content code for identifying the communication system content, the capacity of the communication system content, the name (content name) of the communication system content, and the communication system. The content genre and the keywords as characteristic items that characterize the communication content such as the contents and performers. In the information management DB 520, communication content data that can be distributed to the broadcast receiver 600 by the distribution server 560 is registered in association with the communication content related data.

  Next, the user registration operation will be described. The customer management server 530 in the service center 500 registers data (user registration data) related to the user of the broadcast receiver 600, which is a customer, in the customer management DB 540. For example, the customer management server 530 receives the user registration data generated and transmitted by the broadcast receiver 600 according to the user's operation of the remote control device 650 via the communication network 800 and the communication unit 570, and the customer management DB 540. Register with Alternatively, the customer management server 530 generates user registration data by itself according to the operation of the operator and registers it in the customer management DB 540. An example of user registration data is shown in FIG. The user registration data shown in FIG. 6 includes a user ID for identifying the user (for example, an ID of an IC card lent to the user), the age, sex, address, favorite genre, and usage of the user. And a favorite keyword as a person feature item. The customer management server 530 uses this user registration data at the time of user authentication processing and billing processing.

  Further, the customer management server 530 in the service center 500 updates the user registration data as needed in response to a request from the user of the broadcast receiver 600. Specifically, when a user of the broadcast receiver 600 inputs user registration data using the remote control device 650, the broadcast receiver 600 transmits the user registration data to the communication network 800 and the service center 500. The data is transmitted to the customer management server 530 via the communication unit 570. The customer management server 530 updates the user registration data registered in the customer management DB 540 to the received user registration data.

  Further, the customer management server 530 in the service center 500 outputs the user registration data to the information guidance server 550 every time user registration data is registered or updated. In the information guide server 550 shown in FIG. 2, user registration data from the customer management server 530 is held in the user DB 552. The customer management server 530 in the service center 500 transmits the user registration data to the customer management server 410 in the customer management center 400 via the communication unit 570 and the communication network 700 every time user registration data is registered or updated. The customer management server 410 in the customer management center 400 registers the received user registration data in the customer management DB 420 and transmits it to the program distribution system 210 in each broadcasting station 200. The program distribution system 210 in each broadcasting station 200 holds the received user registration data. For example, when providing a broadcast program only to a specific user, the program distribution system 210 transmits a user ID in user registration data corresponding to the specific user together with the program data.

  Thus, by performing program registration and user registration, the user of the broadcast receiver 600 can receive provision of broadcast programs and communication-related contents, and an information guide server in the service center 500 It is possible to receive guidance of recommended information (broadcast programs recommended for users and communication contents) according to 550.

  The operation at the time of program broadcast and recommended information guidance is shown in FIG. When the user performs a power-on operation using the remote controller 650, the remote controller 650 transmits a power-on request to the broadcast receiver 600 (S101). Further, when the user performs a channel selection operation using the remote control device 650, the remote control device 650 transmits channel selection data to the broadcast receiver 600 (S102). At this time, the broadcast receiver 600 is turned on to receive control data such as SI / EPG (electronic program guide) transmitted from the broadcast station 200 and also receive broadcasts (S103, S104).

  Specifically, the program distribution system 210 in each broadcasting station 200 performs predetermined modulation processing on control data such as SI / EPG and program data (video data and audio data) of the broadcast program, The signal obtained by modulation is sent out. Tuner channel selection unit 601 in broadcast receiver 600 shown in FIG. 3 performs channel selection processing under the control of system control unit 608, and outputs a signal received by antenna 614 to demodulation unit 602. The demodulator 602 demodulates the input signal and outputs data obtained by the demodulation to the decoder 603.

  The decoding unit 603 separates the input data into control data such as SI / EPG, video data, and audio data by the demultiplexing function. Further, the decoding unit 603 outputs identification / attribute data included in the SI or the like in the control data to the memory 611. The identification / attribute data processing unit 610 acquires the program code included in the identification / attribute data from the memory 611 by the identification / attribute data acquisition function and holds it. The program code held by the identification / attribute data processing unit 610 identifies the broadcast program viewed by the user. Note that the identification / attribute data processing unit 610 holds only the first acquired program code when the user continuously acquires the same program code as a result of continuously viewing the same broadcast program. As a result, the identification / attribute data processing unit 610 acquires and retains the program code only immediately after power-on and immediately after the user's channel selection operation, and the identification / attribute data processing unit 610 performs the same broadcast. It is possible to prevent a plurality of program codes corresponding to a program from being held, and to minimize the program codes held by the identification / attribute data processing unit 610.

  Further, the decoding unit 603 decodes the program data by using the audio signal decoding function and the video signal decoding function, outputs the audio signal to the audio output processing unit 604, and outputs the video signal to the video output processing unit 605. The audio output processing unit 604 outputs the input audio signal to an audio output medium such as a speaker. On the other hand, the video output processing unit 605 outputs the input video signal to a video output medium such as a monitor via the screen synthesis processing unit 606. When the program distribution system 210 in the broadcast station 200 provides a broadcast program only to a specific user, the user ID in the user registration data corresponding to the specific user is transmitted together with the program data. The decoding unit 603 uses the CA processing function to read the user ID included in the data from the demodulation unit 602 and the user read from the IC card (not shown) inserted in the IC card IF unit 607. Only when these user IDs match with the ID, the program code is output to the identification / attribute data processing unit 610 and the program data is decoded.

  Next, the broadcast receiver 600 generates viewing history data at a predetermined timing (S105). Specifically, the identification / attribute data processing unit 610 in the broadcast receiver 600 shown in FIG. 3 is included in the held program code and the identification / attribute data in the memory 611 by the identification / attribute data management function. Viewing history data is generated based on the program guide data and the user ID read from the IC card inserted in the IC card IF unit 607. An example of viewing history data is shown in FIG. The viewing history data shown in FIG. 8 includes a user ID, a history management ID, a broadcasting station ID of a broadcasting station 200 that is a transmission source of a broadcasting program viewed by the user, and a program code of the broadcasting program viewed by the user. Is done. Among these, the user ID is read from the IC card inserted in the IC card IF unit 607, and the broadcast station ID is the broadcast that the user has watched among the program guide data stored in the memory 611. The program code is extracted from the program guide data corresponding to the program code of the program, and the program code is held by the identification / attribute data processing unit 610. The generated viewing history data is stored in the memory 611.

  Note that the identification / attribute data processing unit 610 excludes broadcast programs that are considered not to be viewed from the viewing history data generation target when the user repeats channel selection in a short time by so-called zapping. It may be. In this case, for example, when the time from acquiring the program code from the decoding unit 603 to acquiring the next program code is less than or equal to a predetermined time, the identification / attribute data processing unit 610 first The broadcast program corresponding to the program code of the one acquired in the above is excluded from the generation target of viewing history data.

  Next, the broadcast receiver 600 transmits the generated viewing history data to the information guide server 550 in the service center 500. Specifically, the communication unit 609 in the broadcast receiver 600 shown in FIG. 3 reads the viewing history data in the memory 611 and outputs it to the communication network 800. The viewing history data output to the communication network 800 is input to the information guide server 550 via the communication unit 570 in the service center 500. In the information guide server 550 shown in FIG. 2, the viewing history data from the broadcast receiver 600 is registered in the viewing history DB 551 (S106).

  Next, the information guidance server 500 analyzes the user preference of the broadcast receiver 600 (S107).

  FIG. 9 shows a flowchart of the detailed operation of the preference analysis in S107. The preference analysis unit 554 in the information guide server 500 shown in FIG. 2 has a preference history corresponding to the user of the broadcast receiver 600 that is the target of preference analysis among the viewing history data registered in the viewing history DB 551. Data is read (S501). Further, the preference analysis unit 554 determines whether or not the read viewing history data is new viewing history data (S502). Here, the new viewing history data refers to viewing history data registered in the viewing history DB 551 after the previous preference analysis. For example, every time the preference analysis is completed, the preference analysis unit 554 deletes the viewing history data registered in the viewing history DB 551 so that all the viewing history data read from the viewing history DB 551 in the next preference analysis is new viewing. It becomes history data. In this case, when the viewing history data is registered in the viewing history DB 551, the preference analysis unit 554 determines that the viewing history data is new.

  In the case of new viewing history data, the preference analysis unit 554 is a user corresponding to the user of the broadcast receiver 600 that is the target of preference analysis among the user registration data registered in the user DB 552. The registered data is read (S503).

  On the other hand, when there is no new viewing history data, the preference analysis unit 554 corresponds to the user of the broadcast receiver 600 that is the target of preference analysis among the user registration data registered in the user DB 552. The user registration data is read (S504), and it is further determined whether or not the read user registration data is new user registration data (S505). Here, the new user registration data refers to user registration data registered after the previous preference analysis. For example, each time the preference analysis is completed, the preference analysis unit 554 deletes the user registration data corresponding to the user of the broadcast receiver 600 for which the preference analysis is performed, from the user DB 552, thereby obtaining the next preference. All the user registration data read from the user DB 552 in the analysis becomes new user registration data. In this case, when the user registration data is registered in the user DB 552, the preference analysis unit 554 determines that it is new user registration data. If it is determined in S505 that there is no new user registration data, the series of operations ends.

  On the other hand, the preference analysis unit 554 reads the user registration data in S503 or determines that there is new user registration data in S505, and then, among the preference basic data registered in the preference analysis DB 553, The basic preference data corresponding to the user of the broadcast receiver 600 that is the target of preference analysis is read (S506). An example of basic preference data is shown in FIGS. The preference basic data shown in FIG. 10 includes a user ID, a genre, and keywords as basic feature items. Here, the numerical values (A, B) in parentheses attached to the keyword indicate that A is the number of times (the number of times viewed) that the user of the broadcast receiver 600 has viewed the broadcast program having the keyword in the past, and B is A numerical value (viewing rank) indicating a tendency of preference based on an elapsed time since the user of the broadcast receiver 600 last viewed a broadcast program having the keyword. On the other hand, the preference basic data shown in FIG. 11 includes user IDs and keywords that are rearranged in ascending order of viewing rank.

  Next, the preference analysis unit 554 extracts the user registration data read in S503 or S504 and the keywords included in the preference basic data read in S506, and the program related data registered in the information management DB 520. Among them, keywords in the program related data including new viewing history data are extracted. Further, the preference analysis unit 554 performs predetermined arrangement on the extracted keywords (S507). For example, if the extracted keywords overlap, the preference analysis unit 554 organizes them together.

  Next, the preference analysis unit 554 counts the number of times of viewing for each keyword after extraction and arrangement in S507 (S508).

  FIG. 12 shows a flowchart of the detailed operation of viewing count in S508. The preference analysis unit 554 counts the number of times the target keyword has been viewed since the previous preference analysis (S601). Specifically, the preference analysis unit 554 has a combination of the broadcast station ID and the program code included in the new viewing history data read in S501 of FIG. 9 among the program related data from the information management server 510. Extract. The program-related data extracted here corresponds to the broadcast program viewed by the user of the broadcast receiver 600 since the previous preference analysis. Furthermore, the preference analysis unit 554 counts the number of target keywords included in the extracted program-related data.

  Next, the preference analysis unit 554 views the number of views associated with the target keyword in the preference basic data read in S506 of FIG. 9, in other words, the number of views until the previous preference analysis, and the previous count counted in S601. By adding the number of times of viewing after the preference analysis, the number of times of viewing accompanying the target keyword in the preference basic data is updated (S602).

  Next, the preference analysis unit 554 determines whether the target keyword is included in the user registration data read in S503 or S504 of FIG. 9 (S603). When the target keyword is included in the user registration data, the preference analysis unit 554 adds 1 to the number of views since the previous preference analysis counted in S601 (S604). Note that the numerical value to be added does not necessarily have to be 1. On the other hand, when the target keyword is not included in the user registration data, the preference analysis unit 554 does not perform the operation of S604.

  By performing the operations from S601 to S604 for each keyword, the number of viewing times is counted for each keyword.

  Again, returning to FIG. The preference analysis unit 554 calculates a viewing rank for each keyword after being extracted and arranged in S507 (S509).

  FIG. 13 shows a flowchart of detailed operations for calculating the viewing rank in S509. The preference analysis unit 554 determines whether or not there is no viewing record until the previous preference analysis for the broadcast program having the target keyword (S701). Specifically, the preference analysis unit 554 determines that there is no viewing record until the previous preference analysis when the number of views associated with the target keyword is “0” in the preference basic data read in S506 of FIG. If the value is other than “0”, it is determined that there is a viewing record by the previous preference analysis.

  If there is no viewing record until the previous preference analysis for the broadcast program having the target keyword, the broadcast program having the target keyword has been viewed for the first time by the user of the broadcast receiver 600 after the previous preference analysis. It is. In this case, in order to emphasize the latest preference of the user of the broadcast receiver 600, it is desirable that the viewing rank for the target keyword is higher. Therefore, the preference analysis unit 554 sets “1” indicating that it is the highest viewing rank for the target keyword (S705).

  On the other hand, if there is a viewing record for the broadcast program having the target keyword by the previous preference analysis, the preference analysis unit 554 determines whether there is no viewing record for the broadcast program having the target keyword since the previous preference analysis. Is determined (S702). Specifically, the preference analysis unit 554, when the number of views since the previous preference analysis for the target keyword counted in S601 of FIG. 12 is “0”, the viewing results after the previous preference analysis. If the value is “1” or more, it is determined that there is a viewing record since the previous preference analysis.

  When there is no viewing record since the previous preference analysis for the broadcast program having the target keyword, it is desirable that the viewing rank for the target keyword is lower in order to emphasize the latest preference of the user of the broadcast receiver 600. . Therefore, the preference analysis unit 554 adds 1 to the viewing rank for the target keyword calculated during the previous viewing analysis, in other words, the viewing rank for the target keyword in the preference basic data read in S506 of FIG. Then, the viewing rank at the time of the preference analysis is calculated (S706).

  On the other hand, if there is a viewing record for the broadcast program having the target keyword after the previous preference analysis, the preference analysis unit 554 views the target keyword in the previous preference analysis, in other words, S506 in FIG. The number of times of viewing since the previous preference analysis (the value counted in S601 in FIG. 12 or the value added by 1 in S604) is subtracted from the viewing rank in the preference basic data read in (S703).

  Next, the preference analysis unit 554 determines whether or not the viewing rank for the target keyword calculated in S703 is less than 1 (S704). When the viewing rank for the target keyword is 1 or more, the series of operations ends. In this case, the viewing rank calculated in S703 is the viewing rank in the current preference analysis.

  On the other hand, when the viewing rank for the target keyword is 1 or more, the preference analysis unit 554 sets “1” indicating the highest rank in the viewing rank for the target keyword (S705).

  Again, returning to FIG. The preference analysis unit 554 uses the preference basic data in the preference analysis DB 553 based on the number of views calculated in S602 of FIG. 12, that is, the number of views until the current preference analysis and the view rank calculated in S509 for the target keyword. Is updated (S510). When the preference analysis for the user of the broadcast receiver 600 is performed for the first time, the preference analysis data corresponding to the user is not registered in the preference analysis DB 553. In this case, for the target keyword, the preference analysis unit 554 uses the number of views calculated in S602 of FIG. 12, that is, the number of views until the current preference analysis, and the view rank calculated in S509 to store the preference in the preference analysis DB 553. Basic preference data is generated and registered in the preference analysis DB 553.

  Again, returning to FIG. The user performs a predetermined operation using the remote control device 650, for example, displays a menu screen as shown in FIG. 14 on a monitor (not shown) of the broadcast receiver 600, and is an option on the menu screen. When an operation of selecting “recommended information guidance” is performed, remote control device 650 transmits an information guidance request to broadcast receiver 600 (S108). The broadcast receiver 600 transmits the received information guidance request to the information guidance server 550 in the service center 500 (S109). Specifically, the system control unit 608 in the broadcast receiver 600 shown in FIG. 3 outputs the information guidance request received by the built-in receiving unit (not shown) to the communication unit 609. The communication unit 609 outputs this information guidance request to the communication network 800. The information guidance request output to the communication network 800 is input to the information guidance server 550 via the communication unit 570 in the service center 500. The information guidance request includes, for example, a user ID, and the information guidance server 550 can recognize from which broadcast receiver 600 the request is made.

  When the information guidance server 550 receives the information guidance request, the information guidance server 550 determines a broadcast program or communication content (recommended information) to be recommended to the user based on the result of the preference analysis of the user of the broadcast receiver 600 in S107. (S110).

  FIG. 15 shows a flowchart of detailed operations for determining recommended information in S110. The recommended information determination unit 555 in the information guide server 500 shown in FIG. 2 extracts keywords corresponding to the upper predetermined number of viewing ranks from the preference basic data corresponding to the target user in the preference analysis DB 553 (S801).

  Next, the recommended information determination unit 555 selects a keyword related to the extracted keyword (S802). For example, the recommended information determination unit 555 retains a keyword and a keyword whose meaning is similar to the keyword, and selects a keyword whose meaning is similar to the keyword extracted in S801 as a related keyword.

  Next, the recommended information determination unit 555 includes at least one of the keyword extracted in S801 and the related keyword selected in S802 among the program related data and the communication system content related data from the information management server 510. Data and communication-related content-related data are selected (S803). The selected program-related data and communication-related content-related data are output to the recommended information providing unit 556 as recommended program-related data and recommended communication-related content-related data.

  Again, returning to FIG. The recommended information providing unit 556 in the information guide server 550 collects the recommended program related data and the recommended communication content related data as information guide data to the requesting broadcast receiver 600 via the communication unit 570 and the communication network 800. Transmit (S111).

  An example of the information guidance data is shown in FIG. The information guide data shown in FIG. 16 includes a management ID, a broadcast station ID when the recommended information is a broadcast program, and an information code (if the recommended information is a broadcast program, the program code and the recommended information are communication contents. If there is a content code), the broadcast date, start time and end time when the recommended information is a broadcast program, and an information name (if the recommended information is a broadcast program, the program name and the recommended information are the communication system) In the case of content, the content name), the genre of the recommended information, the content of the recommended information, and keywords that are information characterizing the broadcast program such as performers.

  The broadcast receiver 600 displays information guidance based on the received information guidance data (S112). Specifically, the communication unit 609 in the broadcast receiver 600 shown in FIG. 3 stores the received information guide data in the HDD 612. The on-screen control unit 613 reads the information guide data in the HDD 612, generates an information guide screen based on the information guide data, and outputs the video signal to the screen composition processing unit 606. The screen synthesis processing unit 606 synthesizes the video based on the video signal from the on-screen control unit 613 with the video based on the video signal from the video output processing unit 605, and outputs the synthesized video to a video output medium such as a monitor.

  FIG. 17 shows an example of the information guidance screen. In the information guide screen shown in FIG. 17, for a broadcast program, the program name of the broadcast program, broadcast date and time, broadcast station name, recording reservation column and charge are displayed, and for communication content, the content name of the communication system content and The action column is displayed.

  Again, returning to FIG. When a user of the broadcast receiver 600 performs a selection operation of a broadcast program or communication-related content in the information guide screen using the remote control device 650, the remote control device 650 transmits information selection data corresponding to the operation to the broadcast receiver 600. (S113). The broadcast receiver 600 performs a selection process of a predetermined broadcast program or communication content according to the received information selection data (S114). For example, when the user of the broadcast receiver 600 selects the recording of “drama A”, which is a broadcast program on the information guide screen shown in FIG. 17, the system control unit 608 in the broadcast receiver 600 shown in FIG. The processing related to the recording reservation is performed according to the information selection data received by the receiving unit.

  Thus, in the content guidance service system of this embodiment, the viewing history data of the broadcast program received by the broadcast receiver 600, in other words, the broadcast program viewed by the user of the broadcast receiver 600 is stored in the service center 500. When sent to the information guide server 550, the information guide server 550 analyzes the user preference of the broadcast receiver 600 based on the keyword of the broadcast program corresponding to the viewing history data, and broadcasts based on the analysis result. Broadcast programs and communication contents satisfying a predetermined condition according to the user's preference of the receiver 600 are determined, and information guide data corresponding to the determined broadcast programs and communication contents are transmitted to the broadcast receiver 600. Then, the broadcast receiver 600 outputs predetermined guide information related to the broadcast program or communication content according to the preference based on the received information guide data. Therefore, it is not necessary for the broadcast receiver 600 to analyze the user's preferences, the configuration is simplified, and when the broadcast receiver 600 is exchanged, the user's work of registering and migrating data regarding preferences is not necessary. It becomes unnecessary, and it becomes possible to eliminate complexity.

  Further, when calculating the viewing rank in the preference analysis, the information guidance server 550 determines that the target keyword is received when the broadcast program corresponding to the target keyword is received by the broadcast receiver 600 for the first time after the previous preference analysis. The viewing rank is set to 1 so that the corresponding preference tendency becomes high. In addition, when the broadcast program corresponding to the target keyword is not received by the broadcast receiver 600 after the previous preference analysis, the information guidance server 650 reduces the viewing rank so that the preference tendency corresponding to the target keyword is low. Add 1 to. Therefore, it is possible to provide guidance that emphasizes the latest preference tendency of the user of the broadcast receiver 600.

  Further, the information guidance server 550 recommends not only content corresponding to a keyword with a higher viewing rank but also content corresponding to a keyword related to the keyword based on a predetermined relationship between keywords. Since it can be determined as the content to be corrected, more appropriate content guidance is possible.

  In the above-described embodiment, a broadcast program or communication content is used as the content. However, other information such as information on an Internet site may be used. When information on an Internet site is used, each information is identified by a URL. In the above-described embodiment, the keyword is used as the feature item. However, other data such as a genre may be used as the feature item.

  As described above, the content guidance service system, the content guidance device, the content guidance method, and the content guidance program according to the present invention do not require the terminal device to analyze the user's preference, and the configuration is simplified, and the terminal When a device is exchanged, there is no need to register or transfer data relating to preferences by users, and it is possible to eliminate complexity, which is useful as a content guidance service system or the like. .
