(System operation)
Next, the operation of the recommended program information providing apparatus according to the embodiment of the present invention will be described with reference to FIGS.

<Overview>
FIG. 7 is a diagram showing an outline of the operation of the recommended program information providing apparatus 10. First, an overview of processing executed by the recommended program information providing apparatus 10 will be described with reference to FIG.

  Step 1) Program identification processing: The program identification unit 13 identifies a program (program ID) as a recommendation target from the message stored in the message storage unit 10.

  Step 2) Distribution destination determination process: The recommended program information distribution destination determination unit 14 determines a distribution destination to distribute the recommended program information related to the program identified in Step 1.

  Step 3) Distribution processing: The recommended program information distribution unit 15 creates recommended program information and distributes it to the distribution destination determined in Step 2 at an appropriate timing.

  Hereafter, each said process is demonstrated in detail.

<Program identification process>
First, the program specifying process executed by the program specifying unit 13 will be described with reference to the flowchart of FIG.

  The program specifying unit 13 refers to the message storage unit 16 at regular time intervals to check whether a new message has been written, and when a new message (hereinafter referred to as message A) is written, Process.

  Step 101) The message A writing time (denoted as posting time A) is acquired from the message storage unit 16.

  Step 102) The title of the bulletin board to which the message A belongs in the message storage unit 16 is acquired, and nouns are extracted from the bulletin board title. In the program information storage unit 17, a program whose posting time A is included in the program providing time range, or a program whose posting time A is included in a range obtained by extending the time before and after the program providing time by a predetermined time. By comparing the ID with the noun, if there is a program ID that matches the noun or has a similarity to the noun higher than a predetermined threshold, this is extracted. Various existing methods may be used as a method for calculating the similarity between character strings. When a plurality of nouns are extracted from the bulletin board title, the above extraction process is performed for each noun.

  When a plurality of program IDs are extracted, one program ID is extracted using criteria such as the program ID having the highest similarity and the ID of the program closest to the start of the program providing time.

  If the program ID can be extracted in step 102, the process proceeds to the distribution destination determination process. If the program ID cannot be extracted, the process proceeds to step 103. If there is no bulletin board title, the process proceeds to step 103.

  In the present embodiment, as described above, a program whose broadcast time is close to the posting time is targeted for search, thereby increasing the specific accuracy.

  Step 103) Referring to the message storage unit 16, the first message posted on the bulletin board to which the message A belongs (this is described as a message S) is acquired. If message A is the first posted message, message A = message S.

  Step 104) For the message S, the same processing as in step 102 is performed. That is, nouns are extracted from the message S. Then, in the program information storage unit 17, the posting time A is a program included in a range in which the time before and after the program providing time is expanded by a predetermined time (or a program whose posting time A is included in the range of the program providing time). By comparing the program ID with the noun, if there is a program ID that matches the noun or has a similarity to the noun higher than a predetermined threshold, this is extracted. The above extraction process is performed for each of a plurality of nouns extracted from the message S.

  When a plurality of program IDs are extracted, one program ID is extracted using criteria such as the program ID having the highest similarity and the ID of the program closest to the start of the program providing time.

  If the program ID can be extracted in step 104, the process proceeds to a delivery destination determination process. If the program ID cannot be extracted, the process proceeds to step 105.

  Step 105) For each noun extracted from the message S, in the program information storage unit 17, the program time (or the post time A is included in the range in which the posting time A is extended by a predetermined time before and after the program providing time) Compared with the name of the performer (for example, only the main performer or a few major performers) of the program included in the provided time range, it matches the noun, or the similarity to the noun If there is a performer name higher than a predetermined threshold, the program ID of the program is extracted. The above extraction process is performed for each of a plurality of nouns extracted from the message S. In addition, in this process, a bulletin board title and a performer name may be compared.

  If multiple program IDs are extracted, the program ID with the highest similarity compared to the program ID, the program ID with the highest similarity regarding the performer name, the ID of the program closest to the start of the program provision time, etc. One program ID is extracted using the criteria of.

  If the program ID can be extracted in step 105, the process proceeds to the distribution destination determination process. If the program ID cannot be extracted, the process returns to step 101.

  The data extracted by the above processing is stored in the processing data storage unit 19.

  The above processing is only an example. For example, the degree of similarity in the determination in each of the above steps may be scored, and the program ID of the recommended program may be specified by the total score.

  The above processing may be performed only when the message includes a predetermined character string such as a character string meaning that the program was interesting or a character string suggesting recommendation. .

  Moreover, in the above example, the posting time A is the information of the program included in the range expanded by a predetermined time before and after the program providing time, but the posting time A is narrowed down a little more, Only programs that are within the program provision time may be targeted.

  In the above example, the first message was used, but instead of the first message or in addition to the first message, the posted message (message A above) is to be compared with the program ID and performer name. It is good.

<Delivery destination determination process>
Next, the delivery destination determination process executed by the recommended program information delivery destination determination unit 14 will be described with reference to the flowchart of FIG. The following process relates to the message A in the program specifying process and the specified recommended program ID. Further, the following processing is processing related to one user (described as user X) stored in the user information storage unit 18, and the following processing is performed for each user as shown in step 220. It is.

  Step 201) Referring to the condition setting information of the user X in the user information storage unit 18, it is confirmed under what conditions the delivery destination is determined. In the following, for the delivery destination determination conditions of “same group”, “specific user”, “number of comments”, “loose connection relationship”, “with viewing behavior history”, steps 202, 203, 204, 205, respectively, Assume that processing 206 is performed. A user who selects “with viewing behavior history” is a user who has accumulated history using this service for a certain period of time.

  Step 202) “Same group”: In this case, it is determined whether or not the user ID of the message A sender (user ID_A) belongs to the same group as the user X in the user information storage unit 18. The process proceeds to step 210. If not, the process proceeds to step 220.

  Step 203) “Specific user”: In this case, it is determined whether or not the user ID_A of the message A sender is included in any of the specific user IDs registered for the user X in the user information storage unit 18. If yes, go to Step 210; otherwise, go to Step 220.

  Step 204) “Number of comments”: In this case, with reference to the message storage unit 16, it is determined whether or not there are more than a predetermined number of messages originating from the user ID_A on the bulletin board to which the message A belongs. If there are more than the predetermined number, the process proceeds to step 210; otherwise, the process proceeds to step 220. Thus, it can be estimated that a user who has a large number of comments is a user who is enthusiastic about the program.

  Step 205) “Loose connection relationship”: In this case, referring to the “comment history” field in the user X field of the user information storage unit 18, the user X gives a comment to the other user or the user X who made the comment. It is confirmed whether there is a user ID_A as the attached user. If there is, the process proceeds to step 210, and if not, the process proceeds to step 220.

  Step 206) “There is a viewing behavior history”: In this case, the “viewing behavior history” column in the user X field of the user information storage unit 18 is referred to and it is confirmed whether or not there is a user ID_A. If yes, go to Step 210; otherwise, go to Step 220.

  Step 210) The video receiving device ID of the user X is acquired from the user information storage unit 18, and stored in the processing data storage unit 19 in association with the recommended program ID. If another video receiving device ID is already stored, it is additionally stored.

  Step 220) The processing from Step 201 is repeated until the processing for all users is completed.

  In the above example, the determination may be made based on a plurality of conditions such as being in the same group and having loose connections.

  In addition, it is not mandatory for each user to set conditions, and if a default condition is set and there is no setting from the user, the delivery destination is determined based on the default condition (for example, the same group). May be.

<Distribution processing>
Next, the distribution process executed by the recommended program information distribution unit 15 will be described with reference to FIG.

  Step 301) By comparing the program provision time of the program with the program ID identified by the program identification process (referred to as program X) with the current time, the current time is a predetermined time from the provision end time of program X. It is checked whether or not the time is more than (for example, a predetermined proportion of the program providing time). In other words, it is checked whether the program X has been provided or is not about to end.

  Step 302) If the determination in Step 301 is Yes, it is decided to use the program ID specified by the program specifying process as the program information distributed to the video receiving device 20, and the program ID is included in the recommended program information. Hold as information.

  Step 303) If the determination in Step 301 is No, the program information storage unit 17 is searched using the program ID specified in the program specifying process, and the next week's broadcast of the program, the video to be released for the program, etc. Search, extract the corresponding program ID, and retain it as information to be included in the recommended program information. Here, when the corresponding program ID cannot be extracted, the program ID specified in the program specifying process is used.

  Step 304) Next, the provision start time of the program with the program ID held in Step 302 or 303 is compared with the current time, and the current time is a time before the provision start time less than a predetermined time, Alternatively, it is checked whether or not the current time is the time when the program is being provided.

  Step 305) If the result of determination in Step 304 is Yes, that is, if the current time is a time before the provision start time and less than a predetermined time, or if the current time is the time when the program is being provided, Immediately, the recommended program information including the program ID and the user ID_A is transmitted to the video receiving device 20 as the distribution destination. The recommended program information may include a message of the user ID_A that triggered the program identification.

  Step 305) If the result of determination in step 304 is No, that is, if the current time is a time that is a predetermined time or more before the provision start time, the program ID is held. Then, for example, at a predetermined time, the recommended program information including the program ID held so far and the corresponding user ID is transmitted to the distribution destination video receiving device 20 in a lump. Further, with respect to each retained program ID, control may be performed to distribute recommended program information when a certain time before the provision start time of the program comes.

  In the video reception device 20, for example, recommended program information is displayed on a part of the display unit 23 screen. The display here may be displayed so as to overlap the video of the program while viewing the program, or may be displayed overlapping the EPG or video list. The user who has viewed the recommended program information, for example, matches the channel (in the case of a program being broadcast, etc.) in order to view the program recommended by the recommended program information, and makes a recording reservation (when the broadcast is first) And the like are performed on the video receiver 20. When such an operation is performed, the user ID of the user of the video receiver 20 (referred to as user ID_B) and the user who triggered the program identification from the video receiver 20 to the recommended program information providing apparatus 10 ID_A is sent, and in the recommended program information providing apparatus 10, the user ID_A is recorded in the viewing behavior history column of the user ID_B field, and the user ID_B is recorded in the viewing behavior history column of the user ID_A field. These pieces of information are recorded as information about users having similar preferences.

  In addition, the video receiving device 20 that has received the recommended program information may automatically set viewing reservation, recording reservation, and the like based on the program ID included in the received recommended program information.

(Modification)
In the above example, the recommended program providing apparatus 10 determines the distribution destination and transmits the recommended program information to each distribution destination by unicast. However, the recommended program information based on the program specified by the program specifying process May be transmitted to all the video receiving apparatuses 20 to be provided with service by multicast, and the video receiving apparatus 20 may select recommended program information to be displayed on the same basis as the distribution destination determination process.

  In this case, as an overall process, the recommended program providing apparatus 10 performs a program specifying process and a distribution process, which are basically the same as the program specifying process and the distribution process described above. However, in this modification, recommended program information is sent to each video receiving device 20 by multicast. Further, in this modification, the recommended program information can be acquired only on the video receiving device 20 side, and information necessary for making a decision as to whether or not to import the recommended program information is used on the bulletin board to which the message A belongs. Includes the number of times a message with ID_A as the sender is posted.

  It is assumed that each video receiving apparatus that receives recommended program information by multicast holds information on its own field in the table shown in FIG. This information can be periodically acquired and updated from the recommended program providing apparatus 10. Then, each video receiving apparatus that has received the recommended program information by multicast determines whether or not the recommended program information is to be captured by the logic described with reference to FIG. 9, and if so, captures it and displays it on the display unit 23. . The process after the display is the same as the process described above.

  The present invention is not limited to the above-described embodiments, and various modifications and applications are possible within the scope of the claims.
