Default → “5”
Operating volume per minute:
1 to less than 5 → "-1"
5 or more but less than 20 → “-2”
20 or more and less than 50 → "-3"
50 or more → “-4”
Number of keywords:
1 → “+2”
2 or more → “+3”

  This calculation rule sets “5” as an initial value (default) as an audience quality index for a scene identified by the scene number “1” (hereinafter referred to as “scene“ 1 ””). The audience quality index is decreased in accordance with the amount of operation per minute performed by the user U on the operation terminal device 13 during reproduction of “1”, and a predetermined number of scenes subsequent to the scene “1” or the scene “1” If the keyword specified in the “keyword” column is included in the text input by the user U to the operation terminal device 13 during the reproduction of the text or the text displayed in response to the operation of the user U The rule is to increase the audience quality index.

  Further, the following data is exemplified in the “calculation rule” column corresponding to the scene “5” in FIG.

Rate of increase in operating volume per minute:
10% or more and less than 30% → “+1 for the main scene”
30% or more → “Preceding main scene +2”
Number of keywords:
1 → “Corresponding main scene +2”
2 or more → “Corresponding main scene +3”

  The scene “5” is a non-main scene following the main scene. In the “calculation rule” field corresponding to the scene “5”, not the rule for calculating the audience quality index of the scene “5”, but the preceding main scene (a series of main parts following the preceding non-main part). Rules for adjusting the audience quality index of the scene are shown.

  The calculation rule exemplified above is based on the rate of increase when the operation amount per minute increases with the transition from the playback of the scene “4” (main part) to the playback of the scene “5” (non-main part). The rule of increasing the audience quality index of each of the preceding main scenes (in this case, scenes “1” to “4”) is shown.

  In addition, the calculation rule exemplified above is such that a keyword designated as one of the preceding main scenes is input by the user U to the operation terminal device 13 during the reproduction of the scene “5” (non-main part). In the case of being displayed according to the operation of the user U, a rule is shown that the audience quality index of the scene in which the keyword is specified is increased according to the number of the keyword. For example, in the case of following the data illustrated in FIG. 10, if the keyword “Kyoto Temple” is input to the operation terminal device 13 by the user U during the reproduction of the scene “5”, “Kyoto” and “Temple” are set. The audience quality index of the scene “1” in which the keyword is specified is “+3”.

  In addition, the “calculation rule” column corresponding to the scene “6” in FIG. 10 illustrates the following calculation rule in addition to the same type of calculation rule as the calculation rule corresponding to the scene “1”.

Reduction rate of manipulated variable per minute:
10% or more and less than 30% → "Subsequent main scene is +1"
30% or more → “Subsequent main scene +2”

  Scene “6” is a main scene following the non-main scene. The calculation rule illustrated above is based on the rate of decrease when the amount of operation per minute decreases with the transition from scene “5” (non-main part) playback to scene “6” (main part) playback. , The rule of increasing the audience quality index of the scene “6” and the series of main scenes that follow the scene “6”.

  The above-described audience quality calculation rule data is set according to the basic principle shown in FIG. However, the idea shown in FIG. 11 is only a basic principle, and a calculation rule contrary to the basic principle may be set according to the type of content, the content of a scene, and the like. For example, generally, when a keyword related to the main part is input during reproduction of the main part, it is evaluated that the audience quality of the main part by the user U is high. However, for example, when the main story is a drama with a fast story development, if the viewer is concentrating on watching the drama, even if the search is related to the drama, the search operation is performed during playback of the main story. It seems that the search operation is performed after the CM or after watching the drama. Therefore, for such a drama, it is desirable to set a calculation rule for reducing the audience quality index of the scene even when a related keyword is input during the main part.

  FIG. 12 is a diagram illustrating a configuration of audience quality data generated by the audience quality data generation unit 162 according to the audience quality calculation rule data illustrated in FIG. 10 based on the application operation data for each terminal illustrated in FIG. The audience quality data includes columns of “terminal device ID”, “content ID”, “scene number”, and “audience quality index”, and indicates data corresponding to the name of each column.

  The audience quality data generation unit 162 aggregates audience quality data (FIG. 12) indicating audience quality of viewing by various users for each of various contents, and generates audience quality aggregated data. FIG. 13 is a diagram illustrating a configuration of audience quality aggregate data generated by the audience quality data generation unit 162. Audience quality summary data is generated for each content identified by a content ID. Audience quality summary data includes columns for “scene number”, “number of viewers”, “audience quality index (average value)”, and “audience quality index (standard deviation)”. Show. The audience quality aggregated data is transmitted to the requesting terminal device in response to a request from a terminal device (not shown in FIG. 1 or the like) used by the content creator or the like, and is used for the content creator or the like. The

  The audience quality total data indicates the number of viewers and the quality of viewing by those viewers for each of a plurality of scenes constituting the contents for each of various contents. Therefore, content creators, etc., by browsing the audience quality summary data, in addition to information on how many viewers have watched the content, how strong the content is, It is possible to obtain information on whether or not it has been subtracted.

  As described above, also by the content distribution system 2, as with the case of the content distribution system 1, information indicating how much the viewer has viewed the content can be obtained. Further, according to the content distribution system 2, when a plurality of operation terminal devices 23 perform data communication with the content data relay device 24, the user U of those operation terminal devices 23 is a content viewer. Is determined based on the strength of the radio wave received from the operation terminal device 23 by the content data relay device 24. Therefore, the risk that the user U who has not viewed the content is mistaken as a viewer is reduced, and the audience quality is specified with high accuracy.

[Modification]
The content distribution system 1 and the content distribution system 2 described above are one embodiment of the present invention, and can be variously modified within the scope of the technical idea of the present invention. Examples of these modifications are shown below. Two or more of the above-described embodiments and the following modifications may be combined as appropriate.

(1) In the first embodiment, audience quality data is generated by the audience quality management server device 16, and in the second embodiment, audience quality data is generated by the content data relay device 24. The device that generates audience quality data is not limited to the audience quality management server device or the content data relay device, and may be another device. For example, a configuration is adopted in which the operation terminal device 13 stores audience quality calculation rule data in advance and generates audience quality data according to the audience quality calculation rule data based on the application operation data generated by the application operation data generation unit 134. Also good.

(2) Two or more components included in the content distribution system 1 or the content distribution system 2 may be configured as one device. For example, the operation terminal device 13 may also serve as the viewing terminal device 12. In this case, the content data relay device 14 is connected to the operation terminal device 13, and the content is played back on the operation terminal device 13.

(3) In the second embodiment, the content data relay device 24 relays application data transmitted from the operation terminal device 23 to the network 9 and calculates the amount of application data obtained at that time, thereby calculating the operation amount. Generate data. The method of acquiring the data amount of the application data by the content data relay device 24 is not limited to this. For example, a configuration in which the data amount of the application data measured in another device is acquired and used may be employed. For example, as in the first embodiment, when a configuration is employed in which a router is provided separately from the content data relay device 24 and the router relays data communication between the operation terminal device 23 and the network 9, A configuration may be employed in which the data amount of application data transmitted from each operation terminal device 23 to the network 9 is measured, and data indicating the measured data amount is transmitted to the content data relay device 24.

(4) In the first embodiment, the application operation data generated by the operation terminal device 13 is transmitted to the audience quality management server device 16 via the content data relay device 14. Instead, a configuration may be employed in which application operation data generated by the operation terminal device 13 is transmitted to the audience quality management server device 16 without going through the content data relay device 14.

(5) In the first embodiment and the second embodiment, Bluetooth (registered trademark) is exemplified as the first wireless communication protocol, and WiFi (registered trademark) is illustrated as the second wireless communication protocol. The protocol is merely an example, and any other communication protocol may be adopted.

(6) In the first embodiment and the second embodiment, the text input by the user and the content of the text displayed according to the user's operation are used to specify the audience quality as the content of the operation performed by the user. Used for. In specifying the audience quality, the information that can be used as the content of the operation performed by the user is not limited to the text input by the user or the content of the text displayed according to the user operation. For example, data indicating the type of operation performed by the user (different from touch operation, swipe operation, pinch operation, etc.) and the type of the target application operated by the user is used as operation content data for specifying audience quality. A configuration may be employed.

(7) In the first embodiment and the second embodiment, the content of the user U is based on the amount and content of the operation performed on the operation terminal device 13 or the operation terminal device 23 by the user U during the reproduction of the content. Audience quality is identified. Instead of or in addition to this, a configuration in which the audience quality of the content of the user U is specified based on the state of the operation terminal device 13 or the operation terminal device 23 or a change thereof may be employed. For example, when the intensity of the radio wave transmitted from the operation terminal device 13 changes greatly, the user U is likely to be walking around with the operation terminal device 13 during that time. The same applies to the case where the operation terminal device 13 includes an acceleration sensor and the measurement value of the acceleration sensor indicates a large acceleration. Therefore, while the radio wave intensity and the measurement result of the acceleration sensor are greatly fluctuating, it is highly likely that the user U does not concentrate on viewing the content, so it is desirable to lower the audience quality. As in this example, information other than the operation of the user U may be used for specifying audience quality.

(8) In the first embodiment and the second embodiment, both the operation amount data and the operation content data are used for specifying audience quality. Instead, a configuration in which either one of the operation amount data and the operation content data is used for specifying audience quality may be employed.

(9) The audience quality calculation rule data exemplified in the first embodiment and the second embodiment shows rules for calculating the audience quality of the main scene among a plurality of scenes constituting the content. The calculation of scene audience quality is not intended. Instead of this, the audience quality calculation rule data may be configured so that audience quality is calculated only for the non-main part or for both the main part and the non-main part. Further, audience quality calculation rule data that does not distinguish between the main part and the non-main part may be used.

(10) Data indicating the attributes (gender, age, family structure, hobbies, etc.) of the user U (viewers) and the attributes of the viewing environment (content viewing time zone, location, etc.) are associated with the audience quality data. A stored configuration may be employed. In this case, it is possible to obtain information about which attribute the audience quality indicated by the audience quality data is the audience quality of the viewer of which attribute, or in which viewing environment the attribute of the attribute, so that the content creator Desirable for etc.

(11) In the second embodiment, when the data amount of application data is used to specify audience quality, a configuration is adopted in which the evaluation of the data amount is changed according to the type of application, the type of operation performed on the application, or the like. May be. For example, when an operation for instructing uploading of large data is performed, the amount of data transmitted from the operation terminal device 23 to the network 9 is larger than the amount of operation performed by the user U. Therefore, with respect to such an operation, it is desirable not to use the data amount of the application data transmitted to the network 9 as it is to specify the audience quality, but to make a small evaluation by multiplying by an appropriate coefficient.

(12) In the second embodiment, the determination unit 243 determines whether or not the user U of the operation terminal device 23 is viewing the content on the basis of the absolute value of each radio wave intensity of the operation terminal device 23. . Instead, it is determined whether or not the user U of the operation terminal device 23 is viewing content based on the degree of similarity with the radio wave intensity of the operation terminal device 23 functioning as a remote controller. A configuration may be employed.

(13) In the first embodiment and the second embodiment, the level of relevance between the operation performed by the user U on the operation terminal device 13 or the operation terminal device 23 and the scene viewed by the user U is: An audience quality index is identified based on whether or not a keyword related to the scene indicated by the audience quality calculation rule data is included in the text indicated by the operation content data, and based on the number of the identified relevance. The height of is specified. The level of relevance between the content of the operation indicated by the operation content data and the content of the content viewed by the user U may be specified by other than the keyword. For example, when the user U who is viewing the content of a program introducing a game application is operating the game application introduced in the program, the operation is highly relevant to the content. Therefore, for example, the operation content data is configured to indicate the application ID of the application to be operated by the user U, and the application identified by the application ID according to the audience quality calculation rule data is the scene of the content that the user U is viewing. A configuration may be adopted in which the audience quality index is adjusted depending on whether or not the app is related to.

(14) In the first embodiment and the second embodiment, the audience quality is specified for each of a plurality of scenes included in the content. A specific unit of audience quality is not limited to a scene unit, and for example, one audience quality may be identified for one entire content.

(15) The operation terminal device 13 and the audience quality management server device 16 in the first embodiment, and the operation terminal device 23, the content data relay device 24, and the audience quality management server device 26 in the second embodiment are general. This is realized by causing a simple computer to execute processing according to the program of the present invention. Alternatively, these devices may be configured as so-called dedicated machines.
