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.

[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 based on the audience rating data for 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 calculates the estimated overlapping number by expanding and estimating overlapping viewing in audience rating survey panel data obtained from a single-source survey target panel that can survey both broadcast viewing that receives and views the broadcast content transmission and IP viewing that receives and views the IP content transmission, based on demographic statistics.

[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 viewers. The estimated overlapping viewers calculation unit uses audience rating survey panel data obtained from an audience rating survey panel, which is a single source that can survey both broadcast and IP viewing, and by expanding and estimating the audience rating survey panel in accordance with the population ratio, the estimated overlapping viewers can be calculated easily and reliably.

[0010] In this way, according to the content viewing analysis system of the first 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 is characterized in that when expanding and estimating overlapping viewership in the audience rating survey panel data based on demographic statistics, it multiplies the overlapping viewership by a predetermined overlap correction coefficient.

[0012] According to the content viewing analysis system of the second invention, for example, by taking into account devices that are not surveyed by the audience rating survey panel and correcting the overlapping viewing estimate based on demographic statistics, it is possible to calculate an estimated overlapping number that is more in line with reality.

[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 becomes possible to more appropriately evaluate the overall viewing behavior of these contents.

[0014] The content viewing analysis system of the third invention is the first invention, The IP estimated number of people reached calculation unit is characterized in that it calculates the IP estimated number of people reached by multiplying the number of plays, 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.

[0015] According to the content viewing analysis system of the third invention, IP content transmission is the number of plays, which is actual transmission data. In order to convert this into the number of people, for example, the number of plays can be multiplied by a predetermined IP correction coefficient that takes into account cases where one user is viewing using multiple browsers, thereby calculating the IP estimated number of people reached.

[0016] In this way, according to the content viewing analysis system of the third 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 method of a fourth 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 broadcast and an IP content transmission in which the content is transmitted via a network, the method comprising: a broadcast estimated audience calculation step of calculating an estimated audience number of viewers due to the broadcast content transmission from the audience rating 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 expanding and estimating overlapping viewing in audience rating survey panel data obtained from a survey target panel, based on demographic statistics, for broadcast viewing that received and viewed the broadcast content transmission and IP viewing that received and viewed the IP content transmission.

[0018] According to the content viewing analysis method of the fourth 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.

[0019] Here, the question arises as to how to estimate the estimated number of overlapping viewers. In the step of calculating the estimated number of overlapping viewers, audience rating survey panel data obtained from an audience rating survey panel, which is a single source that can survey both broadcast viewing and IP viewing, is used, and the audience rating survey panel is expanded and estimated in accordance with the population ratio, making it possible to easily and reliably calculate the estimated number of overlapping viewers.

[0020] In this way, according to the content viewing analysis method of the fourth 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]

[0021] [Figure 1]1 is a schematic diagram showing a configuration of a content viewing analysis system according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0022] A content viewing analysis system according to one embodiment of the present invention will be described below with reference to FIG.

[0023] 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.

[0024] 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).

[0025] 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.

[0026] 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.

[0027] Here, the broadcast estimated reach calculation unit 11 calculates the estimated reach of the broadcast by the broadcast content transmission from the viewer rating data of the broadcast content transmission.

[0028] 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.

[0029] 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).

[0030] The IP estimated number of people reached calculation unit 12 calculates the IP estimated number of people reached by the transmission of the IP content from the actual measurement data of the transmission of the IP content.

[0031] 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).

[0032] 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.

[0033] The estimated overlap number calculation unit 13 calculates the estimated overlap number of people for broadcast content transmission and IP content transmission.

[0034] More specifically, the estimated overlapping number calculation unit 13 calculates the estimated overlapping number of people by expanding and estimating overlapping viewing in audience rating survey panel data obtained from audience rating survey panel data obtained from a single-source audience rating survey panel that can survey both broadcast viewing that receives and views broadcast content transmissions and IP viewing that receives and views IP content transmissions, based on demographic statistics.

[0035] Here, the estimated overlapping number calculation unit 13 multiplies a predetermined overlap correction coefficient when expanding and estimating overlapping viewership in the audience rating survey panel data based on demographic statistics.

[0036] The specified overlap correction coefficient may be, for example, a correction coefficient that increases the estimated number of overlapping people by taking into account devices that are not surveyed by the audience rating survey panel, a correction coefficient that decreases the estimated number of overlapping people by taking into account device overlap, or a correction coefficient that combines these correction coefficients.

[0037] 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.

[0038] Next, the processing performed by the content viewing analysis system 1 (the content viewing analysis method of the present invention) will be described.

[0039] First, the broadcast estimated number of people reached calculation unit 11 of the content viewing analysis system 1 acquires viewership data for the broadcast content transmission and calculates the estimated number of people reached by the broadcast content transmission from the viewership 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).

[0040] Meanwhile, the estimated overlapping number calculation unit 13 acquires audience rating survey panel data obtained from a single-source survey target panel that can survey both broadcast viewing and IP viewing, and calculates the estimated overlapping number of people by expanding and estimating the overlapping viewing in the acquired audience rating survey panel data based on demographic statistics (estimated overlapping number calculation step).

[0041] Then, once all of the above calculated values ​​have been calculated, 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).

[0042] 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.

[0043] 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. [Explanation of symbols]
