Abstract
Description
[Technical Field]
[0001] The present invention relates to a content viewing analysis system that calculates the total estimated number of people reached by broadcast content transmission, which transmits content via broadcast, and IP content transmission, which transmits the content via a network. [Background technology]
[0002] Conventionally, in a system equipped with broadcast content transmission and IP content transmission, as shown in Patent Document 1 below, a broadcast server that distributes scheduled broadcast content associated with a broadcast time and a plurality of terminals that receive the scheduled broadcast content are connected via a communication network, the Internet, and a system is known in which the broadcast server transmits the scheduled broadcast content around the broadcast time upon request from the terminal processing unit of the terminal, thereby enabling staggered transmission. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Publication No. 2020-65137 Summary of the Invention [Problem to be solved by the invention]
[0004] In such conventional IP content transmission systems, content identical to broadcast content is transmitted at a time difference that differs from the broadcast time (not only due to a time difference (delay) in transmission (sending), but also due to the characteristics of the network, such as delivery delays due to traffic load, variations in network capacity, variations in transmission volume due to differences in image quality, and variations and delays in playback due to buffering during playback and the performance of the IP receiving terminal), which results in varying viewing times, and it is desirable to grasp the actual viewing situation for the same content.
[0005] In particular, since the same content is often transmitted as IP content later than the broadcast time, it is desirable to treat this content as equivalent to broadcast content in order to properly evaluate the content.
[0006] In view of the above circumstances, the present invention aims to provide a content viewing analysis system and a content viewing analysis method that can appropriately evaluate the overall viewing behavior of content that is identical to broadcast content when the content is transmitted as IP content. [Means for solving the problem]
[0007] A content viewing analysis system according to a first aspect of the present invention is a content viewing analysis system that calculates a total estimated number of viewers of a broadcast content transmission in which content is transmitted via broadcasting and an IP content transmission in which the content is transmitted via a network, the content viewing analysis system comprising: a broadcast estimated audience calculation unit that calculates an estimated audience number for the broadcast content transmission from the viewing data of the broadcast content transmission; an estimated IP reach calculation unit that calculates an estimated IP reach number due to the transmission of the IP content from actual transmission measurement data of the IP content transmission; an estimated overlap number calculation unit that calculates an estimated overlap number of the broadcast content transmission and the IP content transmission; a total estimated number of people calculation unit that calculates the total estimated number of people reached by adding the broadcast estimated number of people calculated by the broadcast estimated number of people calculation unit and the IP estimated number of people calculated by the IP estimated number of people calculation unit, and then subtracting the estimated overlapping number of people calculated by the estimated overlapping number calculation unit; Equipped with The estimated overlapping number calculation unit is characterized in that it calculates the estimated overlapping number of people by matching the TV ID and the digital ID from TV log data associated with a TV ID regarding broadcast viewing that received and viewed the broadcast content transmission, and the digital distribution log associated with a digital ID regarding IP viewing that received and viewed the IP content transmission.
[0008] According to the content viewing analysis system of the first invention, the total estimated number of people reached by broadcast content transmission and IP content transmission is calculated by adding the estimated broadcast number of people reached by the broadcast estimated number of people calculation unit and the estimated IP number of people reached by the IP estimated number of people calculation unit, and then subtracting the estimated overlapping number of people calculated by the estimated overlapping number calculation unit.
[0009] The question here is how to estimate the estimated number of overlapping people. The estimated overlapping people calculation unit calculates the estimated number of overlapping people by matching the TV ID and the digital ID from the TV log data associated with the TV ID for broadcast viewing and the digital distribution log associated with the digital ID for IP viewing.
[0010] In this way, according to the content viewing analysis system of the first aspect of the invention, when the same content as broadcast content is transmitted as IP content, it becomes possible to appropriately evaluate the overall viewing status of these.
[0011] The content viewing analysis system of the second invention is the first invention, The estimated overlap number calculation unit matches the television ID with the digital ID by using attributes including at least the gender and age assigned to the television ID and the digital ID as keys, and based on the results, creates a mapping table of people who match the television ID and the digital ID, and identifies overlapping viewers in the mapping table.
[0012] Specifically, according to the content viewing analysis system of the second invention, TV IDs and digital IDs are matched using attributes assigned to them that include at least the gender and age as keys, and based on the results, a mapping table of those who match the TV ID and digital ID is created, and overlapping viewers are identified in the mapping table.
[0013] In this way, according to the content viewing analysis system of the second invention, when the same content as broadcast content is transmitted as IP content, it is possible to actually and appropriately evaluate the overall viewing status of these contents.
[0014] The content viewing analysis system of the third invention is the second invention, The estimated overlap number calculation unit corrects the overlapping viewers identified in the mapping table based on at least the composition ratio of gender and age.
[0015] According to the content viewing analysis system of the third invention, the attribute composition ratios, including gender and age, may differ from those of general audience rating panel data. In order to correct such attribute composition ratios, corrections can be made based on at least the gender and age composition ratios for overlapping viewers identified in the mapping table, thereby making it possible to match the attribute composition ratios of the audience rating panel data.
[0016] In this way, according to the content viewing analysis system of the third aspect of the invention, when the same content as broadcast content is transmitted as IP content, it becomes possible to more appropriately evaluate the overall viewing behavior of these contents.
[0017] A content viewing analysis system according to a fourth aspect of the present invention is the third aspect of the present invention, The estimated overlapping number calculation unit calculates a rate of overlapping viewing using the corrected overlapping viewers, and calculates the estimated overlapping number by applying the rate of overlapping viewing to an expanded estimation.
[0018] According to the content viewing analysis system of the fourth aspect of the present invention, by applying the overlap viewing rate optimized by correction to the expanded estimation, it is possible to calculate a realistic and appropriate estimated overlap number.
[0019] In this way, according to the content viewing analysis system of the fourth aspect of the invention, when the same content as broadcast content is transmitted as IP content, it becomes possible to practically and appropriately evaluate the overall viewing status of these contents.
[0020] A content viewing analysis method of a fifth aspect of the present invention is a content viewing analysis method for calculating a total estimated number of viewers of a broadcast content transmission in which the content is transmitted via broadcasting and an IP content transmission in which the content is transmitted via a network, the method comprising: a broadcast estimated reach calculation step of calculating an estimated number of people reached by the broadcast content transmission from the viewing data of the broadcast content transmission; an IP estimated number of people reached calculation step of calculating an estimated number of people reached by the IP content transmission from the actual transmission measurement data of the IP content transmission; an estimated overlap number calculation step of calculating an estimated overlap number of the broadcast content transmission and the IP content transmission; a total estimated number of people calculation step of calculating the total estimated number of people reached by adding the estimated broadcast number of people calculated in the estimated broadcast number of people calculation step and the estimated IP number of people calculated in the estimated IP number of people calculation step, and then subtracting the estimated overlapping number of people calculated in the estimated overlapping number calculation step; is executed, The estimated overlapping number calculation step is characterized in that the estimated overlapping number is calculated by matching the TV ID and the digital ID from TV log data associated with a TV ID regarding broadcast viewing that received and viewed the broadcast content transmission, and the digital distribution log associated with a digital ID regarding IP viewing that received and viewed the IP content transmission.
[0021] According to the content viewing analysis method of the fifth invention, the total estimated number of people reached by broadcast content transmission and IP content transmission is calculated by adding the estimated broadcast number of people reached in the estimated broadcast number of people calculation step and the estimated IP number of people reached in the estimated IP number of people calculation step, and then subtracting the estimated overlapping number of people calculated in the estimated overlapping number calculation step.
[0022] The question here is how to estimate the estimated number of overlapping viewers. The estimated number of overlapping viewers calculation step calculates the estimated number of overlapping viewers by matching the TV ID and the digital ID from the TV log data associated with the TV ID for broadcast viewing and the digital distribution log associated with the digital ID for IP viewing.
[0023] In this way, according to the content viewing analysis method of the fifth aspect of the invention, when the same content as broadcast content is transmitted as IP content, it becomes possible to appropriately evaluate the overall viewing status of these. [Brief explanation of the drawings]

[Figure 5] FIG. 2 is an explanatory diagram showing the processing details of the content viewing analysis system of FIG. 1. DETAILED DESCRIPTION OF THE INVENTION
[0025] A content viewing analysis system according to one embodiment of the present invention will be described below with reference to FIG.
[0026] As shown in FIG. 1(A), the content viewing analysis system 1 includes a total estimated number of people calculation unit 10, a broadcast estimated number of people calculation unit 11, an IP estimated number of people calculation unit 12, and an estimated overlap number of people calculation unit 13.
[0027] As shown schematically in FIG. 1(B), the content viewing analysis system 1 is a system that calculates the total estimated number of people reached by broadcast content transmission, which transmits content via broadcast, and IP content transmission, which transmits the content via a network, using the calculation formula in FIG. 1(B).
[0028] Here, IP content transmission may be, for example, TVer (registered trademark), which is a free television program distribution service, distribution via the Internet (for example, YouTube (registered trademark)), or even a VOD distribution service.
[0029] Specifically, the total estimated number of people calculation unit 10 calculates the total estimated number of people reached by adding the broadcast estimated number of people calculated by the broadcast estimated number of people calculation unit 11 and the IP estimated number of people calculated by the IP estimated number of people calculation unit 12, and then subtracting the estimated overlapping number of people calculated by the estimated overlapping number calculation unit 13.
[0030] Here, the broadcast estimated reach calculation unit 11 calculates the broadcast estimated reach number of viewers due to the broadcast content transmission from the viewing data of the broadcast content transmission.
[0031] More specifically, the estimated broadcast reach calculation unit 11 obtains the reach determination result based on real-time viewing and whether or not time-shifted viewing has occurred within a specified period through recording, etc. (more precisely, whether or not the broadcast content has been viewed for more than a specified period of time) using an audience rating survey panel, which is a so-called general audience rating survey, as the audience reach rating, and calculates the estimated number of people reached by broadcasting by expanding and estimating the obtained audience reach rating based on demographic statistics.
[0032] In addition to applying the expanded estimate to the entire population, it may also be applied to the population of a specific area. In either case, the estimated number of people reached by the broadcast can be calculated by multiplying the population ratio to the audience rating survey panel (the same applies below to the expanded estimate).
[0033] The IP estimated number of reach calculation unit 12 calculates the IP estimated number of reach due to the transmission of the IP content from the actual measurement data of the transmission of the IP content.
[0034] More specifically, the IP estimated number of people reached calculation unit 12 calculates the IP estimated number of people reached by multiplying the number of plays UB (the number of unique browsers that played the target content), which is the actual transmission data of the IP content transmission, by a predetermined IP correction coefficient to convert it into a number of people, and then calculates the value UU (the number of unique users).
[0035] Here, the predetermined IP correction coefficient is a coefficient for converting the number of views UB, which is the actual transmitted data, into the number of people, and is a coefficient that takes into account, for example, cases where one user is viewing using multiple browsers.
[0036] The estimated overlap number calculation unit 13 calculates the estimated overlap number of people for broadcast content transmission and IP content transmission.
[0037] The estimated overlap number calculation unit 13 calculates the estimated overlap number of people by matching the TV ID and the digital ID from TV log data associated with the TV ID regarding broadcast viewing that has been received and viewed by broadcast content transmission and a digital distribution log associated with the digital ID regarding IP viewing that has been received and viewed by IP content transmission.
[0038] Specifically, as shown in Figure 2, RL data, which is TV log data, is assigned a TV ID, and the TV ID is associated with information about the user, such as gender and age. On the other hand, when using TVer (registered trademark, the same applies below), which transmits IP content, information such as gender and age is associated with the user's digital ID (cookie / AdID) and user survey data.
[0039] Therefore, the estimated overlapping number calculation unit 13 creates a mapping table in which TV IDs and digital IDs are matched using gender and age information as a key, as shown in the lower part of FIG.
[0040] Next, the estimated overlap number calculation unit 13 identifies viewers of each TV ID from the RL data, which is TV log data associated with the TV ID, as shown in FIG. 3 (◯ in the table indicates viewers, and × indicates non-viewers).
[0041] Furthermore, the estimated overlap number calculation unit 13 identifies viewers of TVer's broadcasts by matching using the digital ID (cookie / AdID) as a key (◯ in the table indicates viewers of the broadcasts, and × indicates non-viewers of the broadcasts).
[0042] Then, the estimated overlapping number calculation unit 13 identifies viewers who are both viewers of the identified TV ID and viewers of TVer's broadcast as overlapping viewers (in the table, a circle indicates an overlapping viewer, and an cross indicates a viewer who does not qualify as an overlapping viewer).
[0043] This makes it possible to identify TV ID viewers, TVer distribution viewers, and overlapping viewers of TV ID and TVer, and from this it becomes possible to calculate the overlap rate, which is the proportion of overlapping viewers on TVer, which transmits IP content.
[0044] Overlap rate = number of overlapping viewers ÷ number of viewers of the stream = 41,323 ÷ 206,129 = 20.0472% Here, the estimated overlap number calculation unit 13 creates a weighting value that corrects the gender and age composition of the mapping table to the gender and age composition of the audience rating survey panel, as shown in Figure 4, and calculates the number of overlapping viewers and the overlap rate using this weighting value.
[0045] Corrected overlap rate = Corrected overlapping viewers / Corrected number of viewers = 42,225 / 207,324 = 20.3667% Finally, the estimated overlapping number calculation unit 13 calculates the estimated overlapping number by applying the calculated overlap rate to the expanded estimation, as shown in FIG.
[0046] Here, the IP estimated reach number of 496,000 calculated by the IP estimated reach number calculation unit 12 is multiplied by the corrected overlap rate of 20.3667%, and the overlapping viewer number is calculated to be 101,000.
[0047] The above is the configuration of the content viewing analysis system 1 of this embodiment. In the above configuration, each of the processing units 10 to 13 is configured with hardware such as a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory), and functions as an arithmetic device (sequencer) for executing various processes by storing and holding programs for executing various processes described below in memory (not shown) and executing the programs. Also, some or all of the processing units 10 to 13 may be configured with other servers (external servers), and the content viewing analysis system 1 may be realized by distributed processing.
[0048] Next, the processing performed by the content viewing analysis system 1 (the content viewing analysis method of the present invention) will be described.
[0049] First, the broadcast estimated number of people reached calculation unit 11 of the content viewing analysis system 1 acquires viewing data of the broadcast content transmission and calculates the estimated number of people reached by the broadcast content transmission from the viewing data (broadcast estimated number of people calculation step), and at the same time, the IP estimated number of people reached calculation unit 12 converts the actual transmission data of the IP content transmission into a number of people and calculates the IP estimated number of people reached by the IP content transmission (IP estimated number of people calculation step).
[0050] Meanwhile, the estimated overlapping number calculation unit 13 matches the television ID with the digital ID by using attributes including at least the television ID and the gender and age assigned to the digital ID as keys, creates a mapping table of those who match the television ID and the digital ID based on the results, and identifies overlapping viewers in the mapping table.Furthermore, it performs correction based on the gender and age composition ratio, calculates the overlapping viewer rate using the corrected overlapping viewers, and applies the overlapping viewer rate to the expanded estimation to calculate the estimated overlapping number (estimated overlapping number calculation step).
[0051] Then, once all of the above calculated values have been calculated, as shown in the lower part of Figure 5, the total estimated number of people calculation unit 10 adds the broadcast estimated number of people calculated in the broadcast estimated number of people calculation step and the IP estimated number of people calculated in the IP estimated number of people calculation step, and then calculates the total estimated number of people by subtracting the estimated overlapping number of people calculated in the estimated overlapping number calculation step (total estimated number of people calculation step).
[0052] In this way, according to the content viewing analysis system 1 of the present invention, when the same content as broadcast content is transmitted as IP content, it becomes possible to appropriately evaluate the overall viewing status of these contents.
[0053] In this embodiment, the content may be a target program (television program), a commercial material (television commercial material), or even a radio program or radio commercial without video.
[0054] Furthermore, in this embodiment, the estimated overlap number calculation unit 13 has constructed a mapping table in which television IDs and digital IDs are matched using gender and age information as a key, but in addition to or instead of gender and age, matching may also be performed using other viewer attribute information (attribute information such as information representing income, information representing occupation, information representing the composition of cohabiting family members, information representing viewing attitudes, information representing purchasing attitudes, as well as survey information, etc.).
