  Hereinafter, the first to fourth embodiments of the present invention will be described in detail with reference to the drawings. Note that in the second and subsequent embodiments, description of the same items as those in the previous embodiments will be appropriately omitted.

(First embodiment)
FIG. 1 is an overall configuration diagram of the information processing system S of the first embodiment. The information processing system S includes an information processing device 1 and a plurality of digital broadcast receivers 2. The digital broadcast receiver 2 receives a television broadcast signal, displays a television program on a display unit (not shown), and transmits a viewing history (viewing log), which is the history of the television program viewed by the user, to the information processing device 1. To do. The information processing device 1 is communicatively connected to a plurality of digital broadcast receivers 2 via a network N such as the Internet.

  A television program is content broadcast by, for example, terrestrial digital broadcasting, satellite broadcasting (BS broadcasting, CS broadcasting, etc.), cable television (cable broadcasting), or the like.

  The information processing device 1 includes a processing unit 11, a storage unit 12, an input unit 13, and a display unit 14. Although the information processing apparatus 1 also includes a communication interface, its illustration and description are omitted for the sake of brevity. The information processing device 1 is configured as, for example, a computer (server or the like) including a hardware processor such as a CPU (Central Processing Unit), a memory, an HDD (Hard Disk Drive), and the like. Further, the information processing device 1 may be realized as a cloud server. In that case, for example, the input unit 13 and the display unit 14 may be realized by another device via a communication network.

  The storage unit 12 stores a program information DB 121 (program information storage unit), a viewing history DB 122 (viewing history storage unit), various data, and various programs.

  The program information DB 121 stores program information. Here, an example of the program information stored in the program information DB 121 will be described with reference to FIG. FIG. 2 is a diagram showing an example of program information according to the first embodiment. The program information is composed of information on each item of broadcast date / time (time zone regarding television program), channel, program ID (Identifier), program name and genre. The program information does not need to include information on all of these items, but may include at least information on broadcast date and time and channel. The program information is specifically, for example, an electronic program guide (EPG: Electronic Program Guide). The processing unit 11 stores the program information received via the Internet or the like in the program information DB 121.

  Returning to FIG. 1, the viewing history DB 122 stores the viewing history. Here, an example of the viewing history stored in the viewing history DB 122 will be described with reference to FIG. FIG. 3 is a diagram showing an example of the viewing history of the first embodiment. The viewing history includes information on each item of receiver ID (ID of digital broadcast receiver 2), viewing date / time, channel, and program ID. It should be noted that the viewing history does not need to include information on all of these items, but may include at least the receiver ID, viewing date and time, and channel information. From this viewing history, it becomes possible to know which channel was watched by which digital broadcast receiver 2 from when.

  Returning to FIG. 1, the processing unit 11 includes an acquisition unit 111, a conversion determination unit 112, a viewing determination unit 113, and an index value calculation unit 114. The functions of the respective units 111 to 114 are realized, for example, by the CPU executing a program. Further, some or all of the functions of the respective units 111 to 114 may be realized by a dedicated hardware circuit. Further, in the following, for the processing other than the respective units 111 to 114 in the processing unit 11, the operation subject is described as “processing unit 11”.

  The acquisition unit 111 acquires the viewing history from each of the plurality of digital broadcast receivers 2 and stores the acquired viewing history in the viewing history DB 122.

  The conversion determination unit 112, based on the viewing history stored in the viewing history DB 122 and the program information stored in the program information DB 121, when the first television program is viewed for each digital broadcast receiver 2, When the second television program associated with the first television program is being viewed, the conversion indicating that the purpose of the first television program has been achieved by the viewing of the second television program is It is determined that the conversion has occurred, and conversion history information including the determination result is created.

  Here, for example, the first TV program is a pay program in the pay broadcast service, and the second TV program is a free program aiming at encouraging the pay broadcast service to watch the pay program. is there. In the following, this case is taken as an example, but in addition, the first TV program is a predetermined target TV program, and the second TV program is a broadcast program intended to encourage viewing of the target TV program. It may be.

  The conversion determination unit 112 determines that the pay program and the free program have been viewed, for example, when they have been viewed for a predetermined time or more. The conversion determination unit 112 can determine whether the pay program or the free program is viewed by associating the broadcast date / time and channel in the program information with the viewing date / time and channel in the viewing history. Further, the conversion history information created by the conversion determination unit 112 includes the receiver ID of the digital broadcast receiver 2 and the conversion date and time information.

  The viewing method may be live viewing or playback viewing. In addition, the method of calculating the viewing time during playback viewing may be either a method based on “reach” time that excludes a time zone that is repeatedly viewed, or a method based on “total” time that is totaled without such exclusion. . Further, the above-mentioned predetermined time may be a fixed time or a value of a fixed ratio to the broadcast time. When a value of a fixed ratio to the broadcast time is used, for example, the ratio is set to 0.5, and when the broadcast time is 1 hour, it is judged to be viewed by viewing for 30 minutes or more and 10 minutes for viewing 5 minutes or more. To do. By doing so, it is possible to prevent a television program having a long broadcast time from being more likely to be determined to be viewed than a television program having a short broadcast time.

  In addition, in general, when the pay broadcasting service is not subscribed, a screen or the like for prompting the subscribing to the pay broadcasting service is displayed on the channel of the pay program instead of the pay program. It is unlikely that the user will continue to see such a screen for a long time. Therefore, the length of the above-mentioned predetermined time may be set in consideration of that point. Further, based on the receiver ID of the viewing history and the customer information held by the pay broadcaster, the presence / absence of conversion may be determined using information on whether or not the pay broadcast service is subscribed / unsubscribed.

  The viewing determination unit 113, based on the viewing history stored in the viewing history DB 122 and the program information stored in the program information DB 121, views the free program (second TV program) for each digital broadcast receiver 2. Judgment is made, and viewing history information including the judgment result is created. The viewing determination unit 113 can determine the viewing of a free program by associating the broadcast date / time and channel in the program information with the viewing date / time and channel in the viewing history.

  In addition, the viewing determination unit 113 may determine that the free program has been viewed when the free program is viewed, for example, when the free program is viewed for a predetermined time or more. The viewing history information created by the viewing determination unit 113 includes the receiver ID of the digital broadcast receiver 2, the viewing date and time, and the program ID information.

  The index value calculation unit 114, based on the conversion history information created by the conversion determination unit 112 and the viewing history information created by the viewing determination unit 113, pays for a free program (second TV program) An index value indicating the degree of contribution to the viewing of the first television program) is calculated. For example, the index value is the number of digital broadcast receivers 2 that have been viewed in a certain period before conversion.

  The input unit 13 is a means by which a user inputs information, and is, for example, a keyboard or a mouse. The display unit 14 is a means for displaying information, and is, for example, an LCD (Liquid Crystal Display).

  Here, a first example of index value calculation will be described with reference to FIG. FIG. 4 is an explanatory diagram of a first index value calculation example in the first embodiment. In this example, as the digital broadcast receiver 2, digital broadcast receivers ac are taken as an example. Further, programs a to f are taken as examples of free programs associated with pay programs. In addition, for each free program, the number of digital broadcast receivers 2 watched before conversion is used as an index value.

  A month in which the digital broadcast receivers a and b have been converted (that is, the user has subscribed to the pay broadcasting service) is called a conversion month. Regarding the digital broadcast receiver a, the programs a and b were viewed in the previous month and subscribed in the conversion month. The digital broadcast receiver b is subscribed after the programs a, c, and d have been viewed in the previous month and the program f has been viewed in the conversion month. The digital broadcast receiver c has been subscribed since the programs e and c were viewed in the previous month.

  In such a case, if the index value is calculated by aggregating the digital broadcast receivers 2 that have subscribed (conversion) in the conversion month, first, since the digital broadcast receiver c is not the target, There is no addition of the index values of the viewed programs e and c.

  Also, regarding programs a and b viewed by the digital broadcast receiver a, since the viewing is within a predetermined period before subscription (a period indicated by a double-headed arrow P in the figure, for example, about one month), each index value Is incremented by 1. Also, for programs c, d, and f viewed by the digital broadcast receiver b, since the viewing is within a predetermined period before subscription, one is added to each index value. For program a, since the viewing is not within the predetermined period before joining, the index value is not added.

  In this way, the index value calculation unit 114 can calculate, for each free program, the number of digital broadcast receivers 2 that were viewed within a certain period before conversion as an index value.

  Next, a second index value calculation example will be described with reference to FIG. FIG. 5 is an explanatory diagram of a second index value calculation example in the first embodiment. The difference from the case of FIG. 4 is that the programs broadcast in the broadcast month of FIG. 5 are aggregated to calculate the index value.

  In the case of FIG. 5, for programs a and b viewed by the digital broadcast receiver a, since the viewing is in the broadcast month and within a predetermined period before subscription, one is added to each index value. As for programs c and d viewed by the digital broadcast receiver b, since the viewing is in the broadcast month and within a predetermined period before subscription, one is added to each index value. As for the program a, since the viewing is in the broadcast month but not within the predetermined period before the subscription, the index value is not added. Further, since the viewing of the program f is not on the broadcast month, the index value is not added. As for the programs e and c viewed by the digital broadcast receiver c, since the viewing is in the broadcast month and within the predetermined period before joining, one is added to each index value.

  In this way, the index value calculation unit 114 can calculate, for each free program, the number of digital broadcast receivers 2 that were viewed before conversion as an index value, based on the broadcast month.

  Next, with reference to FIG. 6, processing by the information processing device 1 according to the first embodiment will be described. FIG. 6 is a flowchart showing processing by the information processing device 1 according to the first embodiment. First, in step S1, the conversion determination unit 112, based on the viewing history and the program information, when a free program is viewed for each digital broadcast receiver 2, a pay program associated with the free program is viewed. If so, conversion history information including the determination result is created.

  Next, in step S2, the viewing determination unit 113 determines viewing of the free program for each digital broadcast receiver 2 based on the viewing history and the program information, and creates viewing history information including the determination result.

  Next, in step S3, the index value calculation unit 114 calculates, for each free program, an index value indicating the contribution of the pay program to viewing based on the conversion history information and the viewing history information.

  Next, in step S4, the processing unit 11 displays the index value calculated in step S3 on the display unit 14.

  As described above, according to the information processing system S of the first embodiment, it is possible to quantitatively grasp the conversion regarding the television program. That is, since the index value indicating the degree of contribution of the pay program to viewing is calculated for each free program, if the index value for each free program is displayed on the display unit 14, the user can contribute to the pay program for each free program. The degree can be grasped easily and quantitatively.

  For example, in the case of a Web advertisement, since there is a click operation, the conversion can be grasped quantitatively. However, in the case of a TV program, since there is no operation such as a click operation, it has been impossible to quantitatively grasp the conversion in the past. According to the first embodiment, it is possible to quantitatively grasp the conversion of a television program, and therefore, for example, a broadcasting station, a video distributor, an advertising agency who wants to obtain the maximum results for a limited advertising budget and time frame. And the like can be provided with useful index values.

(Second embodiment)
Next, a second embodiment will be described. In the first embodiment, “1” is added to the index value for each digital broadcast receiver 2 that has been viewed for each free program. In the second embodiment, the index value calculation unit 114 sets, for each free program, an index value of “1 / (the number of free programs viewed by the digital broadcast receiver 2 for each digital broadcast receiver 2 that has been viewed. ) ”Is added.

  Here, it is assumed that there are a plurality of free programs associated with pay programs (the same applies to the third and fourth embodiments). Then, when calculating the index value for each free program (second TV program), the index value calculation unit 114 views the free program (second TV program) viewed before the conversion for each digital broadcast receiver 2. ) Is used to calculate the index value. Hereinafter, a specific example will be described with reference to FIGS. 7 and 8 (the description of matters similar to those in FIGS. 4 and 5 will be omitted).

  FIG. 7 is an explanatory diagram of a third example of index value calculation in the second embodiment. Different from the case of FIG. 4, “½” is added to each index value of the programs a and b viewed by the digital broadcast receiver a.

  Further, for the programs c, d, and f watched by the digital broadcast receiver b, "1/3" is added to each index value, unlike the case of FIG.

  By doing so, the index values are normalized, and the total of the index values of all free programs matches the number of converted digital broadcast receivers 2. As a result, even if the number of free programs viewed by each digital broadcast receiver 2 is different, it is possible to suppress the decrease in the reliability of the index value. Therefore, for example, it is possible to maintain high reliability of the result when the index value is added / subtracted by the genre unit or the broadcast period unit, and compared and analyzed for the free program.

It will be described below using mathematical expressions. The index value S of the free program can be calculated by the following formula (1).

  Here, Wi is the number of free programs that were viewed before conversion by the digital broadcast receiver 2 that was converted after viewing free programs. Further, n is the number of digital broadcast receivers 2 that have been converted after viewing the free program.

  FIG. 8 is an explanatory diagram of a fourth index value calculation example in the second embodiment. Different from the case of FIG. 5, “½” is added to each index value of the programs a and b viewed by the digital broadcast receiver a.

  Further, for the programs c and d viewed by the digital broadcast receiver b, "1/2" is added to each index value, unlike the case of FIG. Also, for the programs e and c viewed by the digital broadcast receiver c, "1/2" is added to each index value, unlike the case of FIG.

  Therefore, the index value calculation unit 114 can calculate the index value for the program c as 1/2 + 1/2 = 1, for example.

  As described above, according to the second embodiment, when adding to the index value for each free program, by adding “1 / the number of free programs viewed by the digital broadcast receiver 2”, It can be used as a reliability index value.

(Third Embodiment)
Next, a third embodiment will be described. In the third embodiment, when the index value calculation unit 114 calculates the index value for each free program (second TV program), the time from viewing the free program (second TV program) to conversion is short. The index value is calculated such that the index value becomes higher.

  This is because when there are multiple free programs that have contributed to conversion, for example, a free program watched the day before the conversion and a free program watched one month before the conversion have a user's memory and impression. Therefore, it is based on the hypothesis that the new free program of the previous day has a higher probability of contributing to the conversion.

The following is an example of a method in which the index value increases linearly as the number of days elapsed from the date of viewing a free program to the date of conversion decreases. When a free program watched up to a maximum of M days before the conversion date is targeted for evaluation, the index value calculation unit 114 calculates the evaluation index value S ′ of a certain free program by the following formula (2).

Here, T _i is the number of days elapsed from the date when the free program was viewed by the digital broadcast receiver 2 (i-th) to the date when the conversion was performed. Further, T _ij is the number of days elapsed from the date when the free program (j-th) was viewed by the digital broadcast receiver 2 (i-th) to the date when it was converted. In addition, m _i is the number of free programs viewed by the day when the conversion is performed by the digital broadcast receiver 2 (i-th). Further, n is the number of digital broadcast receivers 2 that have been converted after viewing the free program.

By subtracting the elapsed days after viewing T _i from M, the value “M−T _i ” which is the basis of the index value is obtained. This value “M-T _i ” corresponds to the total value of all free programs “M-T _i ” watched by the digital broadcast receiver 2 (i-th) (the numerator “M-T _i ” in the formula (2)). By dividing by the denominator), the sum of the added values to the index value of each free program viewed by the digital broadcast receiver 2 (i-th) becomes “1”.

For example, when M is 10 (day), a free program A ₁ for a certain digital broadcast receiver 2 (i-th) 4 days before the conversion, a free program A ₂ and a free program A ₃ 2 days before the conversion, and a free program A ₁ day before the conversion ₄ is viewed, the added value of the digital broadcast receiver 2 (i-th) to the index values of the free programs A _{1 to} A ₄ is as shown in the bottom row of Table 1 below.

  As can be seen from Table 1, the sum of the added values of the index values for each digital broadcast receiver 2 is 6/31 + 8/31 + 8/31 + 9/31 = 1. In this way, by setting the total of the added values to "1", the total of the index values of all free programs becomes equal to the number of converted digital broadcast receivers 2 as in the case of the second embodiment. It is possible to maintain high reliability of the index value and the result of comparison and analysis using the index value.

In addition, in order to reflect the time distance when the free program is viewed and converted by the digital broadcast receiver 2 in the index value, a nonlinear model such as a forgetting curve is used in addition to the linear model described above. May be. When the forgetting curve is used, the memory retention rate (saving rate) at the time point t days after the viewing is used instead of the above-mentioned “M−T _i ”.

  As described above, according to the third embodiment, the shorter the time from the viewing of a free program to the conversion is, the higher the index value is, so that the actual conditions such as the memory and impression of the user who views the free program are reflected. It can be set as an index value with higher reliability.

(Fourth Embodiment)
Next, a fourth embodiment will be described. In the fourth embodiment, when calculating the index value for each free program (second TV program), the index value calculation unit 114 calculates the index value by using the viewing time information of the free program. The details will be described below.

  FIG. 9 is a graph showing the relationship between the viewing time and the index value in the fourth embodiment. In FIG. 9, the vertical axis is (the added value of) the index value, and the horizontal axis is the viewing time. For example, the relationship line L1 is linear, and the longer the viewing time, the larger the index value. This is based on the hypothesis that the longer the viewing time of a free program, the easier it is for the user who views it to remember it, and the greater the degree of contribution to conversion. For example, if the viewing time of the free program is 5 minutes and 60 minutes, the index value of the free program of 60 minutes of viewing time is increased. By doing so, it is possible to make the index value in consideration of the viewing time of the free program.

  The relationship line L2 is non-linear, and the index value is constant (index value V) when the viewing time is longer than a certain amount. This is based on the hypothesis that the contribution to conversion is saturated when the viewing time is long to some extent. For example, if the viewing time of the free program is 3 hours and 4 hours, the index values are not differentiated. By doing so, the index value can be set in consideration of the above-described saturation of the contribution degree.

  Although the embodiment of the present invention has been described, the embodiment is presented as an example and is not intended to limit the scope of the invention. The novel embodiment can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the scope and the gist of the invention, and are also included in the invention described in the claims and the scope equivalent thereto.

  For example, in each of the above-described embodiments, the first television program is a pay program and the second television program is a free program. However, the present invention is not limited to this, and, for example, the first television program may be a predetermined target television program, the second television program may be its broadcast program, or another combination. .

  Further, in the information processing apparatus 1, the display by the display unit 14 has been described as an example of the method of outputting the calculated index value, but the present invention is not limited to this. For example, the calculated index value may be output by voice or may be output as digital data to an external device via a communication interface.

  Further, although the unit of the conversion calculation period is set to a month (one month), the unit is not limited to this, and another unit such as a plurality of months or a week may be used.
