Hereinafter, various embodiments of the present invention will be described with reference to the drawings as appropriate. The same or similar components are designated by the same reference numerals in a plurality of drawings.

A moving image distribution system according to an embodiment will be described with reference to FIGS. 1 and 2. FIG. 1 is a block diagram showing a video distribution system 1 according to an embodiment, and FIG. 2 is a distribution user device used by users Ua, Ub and the users Ua, Ub who distribute a video in the video distribution system 1. It is a schematic diagram which shows 20a, 20b schematically. The distribution user device 20a has a function for distributing a video including a character object generated based on the movement of the user Ua in the video distribution system 1, and the distribution user device 20b is a user in the video distribution system 1. It has a function for delivering a moving image including a character object generated based on the movement of Ub. As will be described in detail later, the video distribution system 1 can generate a video including character objects of two or more distribution users and distribute the video. In other words, in the video distribution system 1, two or more distribution users can virtually co-star in the video via their respective character objects. In this way, when two or more distribution users virtually co-star in a video via their respective character objects, the video is called a co-star video.

Both the user Ua and the user Ub are distribution users who distribute a moving image including a character object generated based on the movement, and are also viewing users who watch the moving images of other distribution users. Therefore, the distribution user devices 20a and 20b may have a function of viewing the moving image distributed by the moving image distribution system 1.

User Ua and User Ub can send invitations to invite other viewing users to their videos. For example, when a moving image including a character object generated based on the movement of the user Ub is distributed, the user Ub can send an invitation to the user Ua to invite the user Ub to the moving image. Based on this invitation, the user Ua can apply for co-starring with the user Ub. When this co-starring application is approved, a co-starring moving image including the character object of the user Ub and the character object of the user Ua is generated, and the co-starring moving image is distributed. When the user Ua participates in the video distributed by the user Ub by an invitation from the user Ub and the user Ub and the user Ua co-star, the user Ub who sent the invitation is called a "host user" and responds to this invitation. The user Ua who co-starred with the user Ub may be referred to as a "guest user". The concepts of host user and guest user are relative. For example, contrary to the above example, when the user Ua co-stars in the video of the user Ua based on the invitation sent by the user Ua to the user Ub, the user Ua becomes the host user and the user Ub becomes the guest user. Become. In the present specification, for convenience of explanation, it is assumed that the invitation is transmitted from the user Ub to the user Ua. That is, it is assumed that the user Ub is the host user and the user Ua is the guest user. However, the description of the user Ua in the present specification may be extended to the description of the guest user in general as much as possible. Similarly, the description of the user Ub herein can be extended to the host user in general as much as possible. For example, even when the distribution user Ua is described in the present specification, the description may be understood as a description regarding the guest user in general, and the description regarding the distribution user Ub may be understood as a description regarding the host user in general.

The video distribution system 1 is assumed to be used by a large number of users. The users of the video distribution system 1 include a distribution user who distributes a moving image and a viewing user who watches the distributed moving image. The users of the video distribution system 1 are divided into distribution users and viewing users depending on the usage mode of the video distribution system 1, but they may also serve as both. That is, a distribution user who distributes a video using the video distribution system 1 can view a video distributed by another distribution user using the video distribution system 1, and thus is a distribution user and a viewing user. possible.

Since the video distribution system 1 is used by a large number of users, it is not easy for the distribution user Ub to search for an appropriate co-star in the above example. That is, it is not easy to determine the destination of the invitation because there are too many candidate distribution users when deciding which distribution user to send the invitation to among the large number of distribution users of the video distribution system 1. Therefore, the video distribution system 1 according to the embodiment of the present invention has a function of supporting the selection of a co-star partner by the distribution user Ub. In the following, the architecture of the video distribution system 1 and the outline of the devices constituting the video distribution system 1 will be described first, and then the functions of each device will be described.

As will be described later, the server device 60 is configured to deliver a moving image including animations of character objects of the delivery user Ua and the delivery user Ub. The server device 60 may be configured to deliver a moving image other than the moving image including the animation of the character object. In addition to the video distribution service, the server device 60 may provide a social networking service for users to interact with each other or a platform function for the service.

In the video distribution system 1, the video is distributed from the server device 60 to the viewing user device 10 and the distribution user devices 20a and 20b. The delivered moving image is displayed on the display of the viewing user device 10. A viewing user who is a user of the viewing user device 10 can view the distributed moving image on the viewing user device 10. The distribution users Ua and Ub can perform the performance while checking the video being distributed by viewing the distributed video. Further, the distribution users Ua and Ub can watch the moving images including the character objects of other users by the distribution user devices 20a and 20b. Although only one viewing user device 10 is shown in FIG. 1 for the sake of brevity, the moving image distribution system 1 may include a plurality of viewing user devices. Further, although only two distribution user devices are shown in FIG. 1, the moving image distribution system 1 may include three or more distribution user devices. As described above, the distribution users Ua and Ub are also viewing users. Therefore, when the own video is not distributed, the video distributed by another distribution user can be viewed by the distribution user devices 20a and 20b.

Contains data. The object data 63b may include object position information indicating the position of the object in the virtual space.

An example of user information 63c is shown in FIG. As shown in the figure, various data related to the user are stored as the user information 63c in association with the account information of the user who uses the video distribution system 1. The user information 63c of a user indicates user evaluation information indicating the evaluation of the user, video evaluation information indicating the evaluation of the video of the video distributed by the user, and the number of viewers of the video distributed or being distributed by the user. Viewer number information, viewing user information about the viewing user of the video distributed or being distributed by the user, co-starring number information indicating the number of times the user has co-starred with another user, attribute information indicating the profile of the user, And social information indicating the relationship between the user and other users may be included. The user information 63c may include information other than the above.

The user account information is, for example, user identification information (user ID) that identifies the user. The user ID is assigned to the user when the user first registers the use of the service in the video distribution system 1.

The user evaluation information associated with the user's account information is information indicating the evaluation of the user by another user. The user evaluation information is, for example, a user evaluation point represented by a natural number. The user of the video distribution system 1 can distribute a video including his / her own character object via the server device 60. The user evaluation points of a user may be updated based on the feedback from the viewing user on the video delivered by the user. For example, feedback from viewers includes selecting a "Like" button that appears on the viewing screen, selecting a "Boo" button that represents a negative rating, and gift gifting for items that appear on the viewing screen. Give a gift), send comments from the viewing screen, and various other feedbacks. It is assumed that the “Like” button is selected when the viewer likes the viewing video or the distribution user who distributes the viewing video. The “Like” button may be displayed as an icon on the viewing screen that includes characters indicating a favorable impression such as “Like” or “Like”. It is assumed that the "boo" button is selected when the viewer has a negative impression such as an antipathy toward the viewing video or the distribution user who distributes the viewing video. The "boo" button may be shown as an icon on the viewing screen that includes characters that indicate "bad" or "dislike". In the present specification, the buttons and icons for showing a favorable impression may be referred to as "favorable button" and "favorable icon", respectively, and the buttons and icons for indicating antipathy may be referred to as "antipathy button" and "antipathy icon", respectively. is there. Evaluation points may include parameters related to the number of positive button selections, the number of negative button selections, the number of gift gifts (or gifting amounts), the number of comments, or other feedback from viewers. For example, the user evaluation points may be increased when positive feedback or negative feedback is given from the viewing user. The user evaluation points may evaluate the number or amount of positive feedback from the viewing user as the number of points, or evaluate the number or amount of negative feedback from the viewing user as the number of points. It may be. Furthermore, the number of positive feedback and the number of negative feedback may increase or decrease the user evaluation points. More specifically, the user evaluation points may be increased when positive feedback is given, decreased when negative feedback is given, or vice versa. The user evaluation points of a user may be updated at an opportunity other than feedback on the video delivered by the user. For example, when a user interacts with another user using the social networking service provided by the server device 60, the user evaluation points may be updated based on the activity using the social networking service.

The video evaluation information associated with the user's account information is information indicating the evaluation of the video distributed by the user from another user. The moving image evaluation information is, for example, a moving image evaluation point represented by a natural number. The video evaluation points of a user may be updated based on the feedback from the viewing user on the video delivered by the user. When a viewing user who has viewed the video gives positive feedback or negative feedback to the video distributed by a user, the video evaluation point of the user may be increased. When feedback is given to a video distributed by a user, both the user evaluation point and the video evaluation point may be updated.

The number of viewers information associated with the user's account information indicates the number of viewing users who have watched or are watching the video delivered by the user. The viewer number information of a certain user may be the cumulative number of viewer users who have watched the video distributed by the user. For example, when a user has distributed a moving image 10 times so far, the number of viewers information may be the total number of viewing users in each of the 10 distributions. A new viewing user may start viewing while the video is being distributed, or a user who has been viewing may stop viewing in the middle. Therefore, the number of users viewing a certain moving image may differ depending on when the measurement is performed from the start of viewing the moving image. The number of viewing users may be logged at regular time intervals, the average of viewing users may be calculated based on this log, and the calculated average may be used as the number of viewing users of the moving image. For example, for a 10-minute moving image, a total of 10 viewers may be recorded at 1-minute intervals, and the average of the 10 recorded viewers may be used as the number of viewing users of the moving image. In another embodiment, the number of viewing users who were viewing the video at the end of distribution of the video may be the number of viewing users. The information on the number of viewers of the moving image may be information other than the above that correlates with the number of viewing users of the moving image.

The viewing user information associated with the user's account information is information about the viewing user who has viewed or is viewing the video distributed by the user. The viewing user information of a certain user may include the user ID of the viewing user who has viewed or is viewing the video delivered by the user. Further, the viewing user information of a certain user may include the number of viewers information indicating the number of viewing users who have viewed or are viewing the moving image distributed by the user. The viewer number information of a certain user may be the cumulative number of viewer users who have watched the video distributed by the user using the video distribution system 1. For example, when a user has distributed a moving image 10 times so far, the number of viewers information may be the total number of viewing users in each of the 10 distributions. A new viewing user may start viewing while the video is being distributed, or a user who has been viewing may stop viewing in the middle. Therefore, the number of users viewing a certain moving image may differ depending on when the measurement is performed from the start of viewing the moving image. The number of viewing users may be logged at regular time intervals, the average of viewing users may be calculated based on this log, and the calculated average may be used as the number of viewing users of the moving image. For example, for a 10-minute moving image, a total of 10 viewers may be recorded at 1-minute intervals, and the average of the 10 recorded viewers may be used as the number of viewing users of the moving image. In another embodiment, the number of viewing users who were viewing the video at the end of distribution of the video may be the number of viewing users. The information on the number of viewers of the moving image may be information other than the above that correlates with the number of viewing users of the moving image.

The number of co-starring information associated with the user's account information indicates the number of co-starring times that the user has co-starred with another distribution user. The co-starring number information may be the total of the number of co-stars with other distribution users as a guest user and the number of co-stars with other distribution users as a host user. The number of co-stars may be the number of co-stars with other distribution users as a host user. The number of co-stars may be the number of co-stars with other distribution users as a guest user.

The attribute information associated with the user's account information indicates the profile of the user. The attribute information of a user may include information indicating the user's nickname, gender, age, place of residence, school of origin, affiliation, and other attributes of the user.

The social information associated with the user's account information is information indicating the relationship between the user and another user. The social information of a certain user includes, for example, friend information that identifies a user registered as a friend by the user and information indicating a relationship between the user and another user other than these. When the server device 60 provides an SNS (social network service) function, the friend information of a certain user is a user of another user registered as a friend of the user in the SNS provided by the server device 60. It may be an ID. The friend information of a certain user may be the user ID of another user registered as a friend of the user in the SNS provided by a device other than the server device 60.

As described above, the user information 63c includes information regarding the usage history of the video distribution system 1 by the user. In the present specification, the information related to the usage history of the video distribution system 1 out of the user information 63c is referred to as "log information". In the example shown in FIG. 3, the viewing user information and the number of co-starring information among the user information 63c are included in the log information. In addition to the viewing user information and the number of co-starring information, the log information may include information on the usage history of the video distribution system 1 by the user.

An example of co-starring video information is shown in FIG. As shown in the figure, as the co-starring moving image information 63d, various data related to the co-starring moving image are stored in association with the co-starring moving image identification information for identifying the co-starring moving image.

The co-starring time information indicates the elapsed time from the start of co-starring between the guest user and the host user.

Next, the functions realized by the computer processors 21a and 21b will be described more specifically. The computer processor 21a functions as a face motion data generation unit 21a1, an invitation presentation unit 21a2, and a co-star application unit 21a3 by executing a computer-readable instruction included in the distribution program. Similarly, the computer processor 21b functions as a face motion data generation unit 21b1 and an invitation request unit 21b2 by executing a computer-readable instruction included in the distribution program. At least a part of the functions realized by the computer processors 21a and 21b may be realized by a computer processor other than the computer processors 21a and 21b of the moving image distribution system 1. At least a part of the functions realized by the computer processors 21a and 21b may be realized by, for example, the computer processor 61 mounted on the server device 60.

The face motion data generation unit 21a1 generates face motion data which is a digital representation of the face movement of the distribution user Ua based on the image data of the camera 24a. Similarly, the face motion data generation unit 21b1 generates face motion data which is a digital representation of the face movement of the distribution user Ub based on the image data of the camera 24b. Face motion data is generated at any time with the passage of time. Face motion data may be generated at predetermined sampling time intervals. In this way, the face motion data generated by the face motion data generation unit 21a1 can digitally represent the face movement (change of facial expression) of the distribution user Ua in time series, and the face motion data generation unit 21b1 The face motion data generated in the above can digitally represent the facial movement (change of facial expression) of the distribution user Ub in time series. The face motion data generated by the face motion data generation units 21a1,21b1 is transmitted to the server device 60 via the communication I / F22a, 22b.

In the distribution user device 20, in addition to the face motion data generated by the face motion data generation unit 21a1, body motion data which is a digital representation of the position and orientation of each part other than the face of the distribution users Ua and Ub. May be generated. The distribution user device 20 may transmit body motion data to the server device 60 in addition to the face motion data. In order to generate body motion data, the distribution users Ua and Ub may be equipped with a motion sensor. The distribution user device 20 may be configured to be able to generate body motion data based on the detection information of the motion sensors attached to the distribution users Ua and Ub. Body motion data may be generated at predetermined sampling time intervals. In this way, the body motion data expresses the body movements of the distribution users Ua and Ub as digital data in chronological order. The generation of body motion data based on the detection information of the motion sensors attached to the distribution users Ua and Ub may be performed in, for example, a shooting studio. The studio may be equipped with a base station, a tracking sensor, and a display. The base station may be a multi-axis laser emitter. The motion sensor mounted on the distribution users Ua and Ub may be, for example, a Vive Tracker provided by HTC CORPORATION. The base station provided in the shooting studio may be, for example, a base station provided by HTC CORPORATION. In addition, a supporter computer may be installed in a room separate from the shooting studio. The display in the shooting studio may be configured to display information received from the support computer. The server device 60 may be installed in the same room where the supporter computer is installed. The room where the supporter computer is installed and the shooting studio may be separated by a glass window. In this case, the operator of the supporter computer (sometimes referred to as "supporter" in the present specification) can visually recognize the distribution users Ua and Ub. The supporter computer may be configured so that the settings of various devices provided in the shooting studio can be changed according to the operation of the supporter. The supporter computer can, for example, set the scanning interval by the base station, set the tracking sensor, and change various settings of various other devices. The supporter can input a message to the supporter computer and display the input message on the display of the shooting studio.

In the distribution user device 20b, the invitation request unit 21b2 requests the server device 60 to transmit the invitation in response to the operation of the distribution user Ub. As will be described later, when the server device 60 receives the invitation transmission request from the distribution user device 20b, the server device 60 selects an invited user to be the destination of the invitation from the users of the video distribution system 1. The invitation is transmitted from the server device 60 to the distribution user device of the invited user. The method of selecting the invited user will be described later, but it is assumed that the distribution user Ua using the distribution user device 20a is included in the invited user. The server device 60 may transmit the host user information regarding the distribution user Ub that requested the transmission of the invitation in association with the invitation from the distribution user Ub. The invitation may be included in the delivered video or may be transmitted separately from the delivered video.

In the distribution user device 20a, when the invitation presentation unit 21a2 receives an invitation from another distribution user from the server device 60, the invitation presentation unit 21a2 presents the invitation to the distribution user Ua. The invitation is, for example, an invitation in which the user Ub invites the user Ua to the video being distributed. The invitation presentation unit 21a2 may present the host user information regarding the distribution user who requested the transmission of the invitation together with the invitation. The invitation presenting unit 21a2 may display the content of the invitation and the host user information regarding the distribution user who transmitted the invitation on the display 23a.

The co-star application unit 21a3 transmits a co-star application for co-starring with the other distribution user to the server device 60 based on the operation of the distribution user Ua on the distribution user device 20a. As will be described later, the distribution user device 20a may display an operation button for applying for co-starring in response to receiving the invitation, and an operation for applying for co-starring regardless of whether or not the invitation has been received. You may display a button.

In the present specification, the distribution user Ub using the distribution user device 20b makes an invitation transmission request, and the server device 60 transmits the invitation from the distribution user Ub to the distribution user Ua using the distribution user device 20a. Assuming, the invitation request unit 21b2 is described as a function executed by the computer processor 21b of the distribution user device 20b. Since it is assumed that the distribution user Ua transmits an invitation, the distribution user device 20a may execute the same function as the invitation request unit 21b2. Similarly, since it is assumed that the distribution user Ub receives the invitation, the distribution user device 20b may execute the same functions as the invitation presentation unit 21a2 and the co-star application unit 21a3.

The distribution user device 20 may realize functions other than the face motion data generation unit 21a1 by executing the distribution program and / or other programs on the computer processor. For example, the distribution user device 20 may realize a function of playing back a received moving image by executing a viewing program for watching a moving image. The distribution program and the viewing program may be packaged in one application software, or may be provided as separate application software.

The viewing user device 10 may be configured to provide the same functions as the distribution user device 20. For example, the viewing user device 10 may realize a function of reproducing the received moving image by executing a viewing program for viewing a moving image, and is similar to the function of the face motion data generation unit 21a1 by executing the distribution program. The function of may be realized.

Next, the functions realized by the computer processor 61 will be described more specifically. The computer processor 61 executes a computer-readable instruction included in the distribution program to execute an animation generation unit 61a, a video generation unit 61b, a video distribution unit 61c, an invited user selection unit 61d, an invitation processing unit 61e, and a co-star application process. It functions as a unit 61f and a co-star end processing unit 61g.

The animation generation unit 61a applies the face motion data generated by the face motion data generation unit 21a of the distribution user device 20a or the face motion data generation unit 21b1 of the distribution user device 20b to predetermined model data included in the model data 63a. By doing so, it is configured to generate an animation of the character object. The animation generation unit 61a can generate an animation of the character object so that the facial expression of the character object changes based on the face motion data. Specifically, the animation generation unit 61a can generate an animation of a character object that moves in synchronization with the movement of the facial expression of the distribution user Ua based on the face motion data related to the distribution user Ua. Similarly, the animation generation unit 61a can generate an animation of a character object that moves in synchronization with the movement of the facial expression of the distribution user Ub based on the face motion data related to the distribution user Ub.

When the distribution user apparatus 20 provides body motion data relating to the distribution users Ua and Ub, the animation generation unit 61a determines the distribution users Ua and Ub based on the body motion data and the face motion data relating to the distribution users Ua and Ub. It is possible to generate an animation of a character object that moves in synchronization with the movement of the body and facial expression.

When distributing the video of the distribution user Ua, the video generation unit 61b generates a background image showing the background using the object data 63b, and the background image, the animation of the character object corresponding to the distribution user Ua, and the animation of the character object corresponding to the distribution user Ua. It is possible to generate a video containing. The moving image generation unit 61b can synthesize the sound of the distribution user Ua generated based on the voice data received from the distribution user device 20a with the generated moving image. Similarly, when the animation of the distribution user Ub is distributed, the moving image generation unit 61b generates a background image showing the background using the object data 63b, and the background image and the character object corresponding to the distribution user Ub. You can generate animations and videos that include. The moving image generation unit 61b can synthesize the sound of the distribution user Ub generated based on the voice data received from the distribution user device 20b with the generated moving image. In the moving image generated by the moving image generation unit 61b, the character objects corresponding to the distribution users Ua and Ub are displayed superimposed on the background image. As described above, the moving image generation unit 61b generates an animation of a character object that moves in synchronization with the movement of the facial expression of the distribution user Ua or the distribution user Ub, and the voice of the distribution user Ua or the distribution user Ub is synthesized with this animation. It is possible to generate a video for distribution.

The moving image distribution unit 61c distributes the moving image generated by the moving image generation unit 61b. This moving image is distributed to the viewing user device 10 and other viewing user devices via the network 50. The generated moving image is also distributed to the distribution user devices 20a and 20b. The received moving image is reproduced in the viewing user device 10 and the distribution user devices 20a and 20b. The video distribution unit 61c may monitor at least one of the video distribution time and the number of distributions for each distribution user. The video distribution unit 61c may update the distribution time and the number of distributions of the user information based on the monitor result.

A display example of the moving image distributed from the moving image distribution unit 61c is shown in FIGS. 5 and 6a to 6b. In these figures, it is assumed that the distribution user Ub distributes a moving image including its own character object using the distribution user device 20b, and the moving image is played back on the viewing user device 10 and the distribution user devices 20a and 20b. ing. In FIG. 6a, it is assumed that the distribution user Ua does not distribute the video and is viewing the video distributed by the distribution user Ub, which is another distribution user. Therefore, in the description of FIGS. 5 and 6a to 6b, the distribution user Ua may also be referred to as a viewing user. FIG. 5 shows a display example of a moving image being played on the viewing user device 10, FIG. 6a shows a display example of a moving image being played on the distribution user device 20a, and FIG. 6b shows a display example of the moving image being played on the distribution user device 20b. A display example of the moving image is shown.

As shown in FIG. 5, the display of the viewing user device 10 displays an image 30 including a moving image distributed from the server device 60. The image 30 displayed on the viewing user device 10 includes a character object 31 of the distribution user Ub generated by the animation generation unit 61a, a gift button 32, an evaluation button 33, a comment button 34, and a comment display area. 35 and are included.

As shown in FIG. 6a, the display 23a of the distribution user device 20a displays the image 40a including the moving image distributed from the server device 60. Similar to the image 30, the image 40a includes a character object 31 of the distribution user Ub, a gift button 32, an evaluation button 33, a comment button 34, and a comment display area 35. In addition to this, the image 40a may include a co-star application button 36. The co-star application button 36 is an operation button for transmitting a co-star application for applying for co-starring with the distribution user Ub in the video distributed by the distribution user Ub. The distribution user Ua can transmit a co-star application for applying for co-starring with the distribution user Ub from the distribution user device 20a to the server device 60 by selecting the co-star application button 36 on the distribution user device 20a. The distribution user device 20a can display the image 40a of the distributed moving image by, for example, executing application software including a viewing program.

As shown in FIG. 5, the image 30 displayed on the viewing user device 10 does not have to include the co-star application button 36. For example, the co-star application button 36 is included when the application software including the distribution program is not downloaded or installed in the viewing user device 10 and when the application software including the distribution program is not started in the viewing user device 10. The image 30 is generated so that there is no such thing. In another embodiment, the co-star application button 36 may also be displayed on the image 30 of the viewing user device 10. For example, the co-star application button 36 is included when the application software including the distribution program is downloaded or installed in the viewing user device 10, or when the application software including the distribution program is started in the viewing user device 10. The image 30 is generated as described above.

Since the character object 31 is generated by applying the face motion data of the distribution user Ub to the model data included in the model data 63a as described above, the character object 31 is synchronized with the movement of the facial expression of the distribution user Ub. The expression changes. When the body motion data is provided from the distribution user device 20, the character object 31 can be controlled so that the parts other than the face also change in synchronization with the movement of the body of the distribution user Ub.

The gift button 32 is superimposed and displayed on the image 30 so as to be selectable by operating the viewing user device 10. The gift button 32 can be selected, for example, by tapping the area of the touch panel of the viewing user device 10 where the gift button 32 is displayed. In one embodiment, when the gift button 32 is selected, the window for selecting a gift to give to the distribution user (here, the distribution user Ub) who is distributing the video being viewed is the image 30. It is superimposed and displayed on. The viewing user can purchase a gift to be gifted from the gifts displayed in the window. In another embodiment, a window containing a list of purchased gifts is superimposed and displayed on the image 30 in response to the selection of the gift button 32. In this case, the viewing user can select a gift to be gifted from the gifts displayed in the window. When the gift button 32 is selected in the viewing user device 10, gifting information may be transmitted to the server device 60. The gifting information may include gift identification information (gift ID) that identifies the gift to be gifted. In this way, the viewing user who is viewing the video can provide (gift) a desired gift to the distribution user who is distributing the video by selecting the gift button 32.

The evaluation button 33 is superimposed and displayed on the image 30 so as to be selectable by the viewing user who uses the viewing user device 10. The evaluation button 33 can be selected, for example, by tapping the area of the touch panel of the viewing user device 10 on which the evaluation button 33 is displayed. When the evaluation button 33 is selected by the viewing user who is watching the video, a positive evaluation is given to the distribution user (distribution user Ub in the illustrated example) who distributes the video, or an affirmation to the distributed video. Evaluation update information indicating that the evaluation has been made may be transmitted to the server device 60. The server device 60 can update the user information based on the evaluation update information from the viewing user. For example, at least one of the user evaluation information and the moving image evaluation information included in the user information may be updated based on the evaluation update information from the viewing user. For example, when the evaluation button 33 included in the image 30 shown in FIG. 5 is selected by the viewing user, the user evaluation information and the moving image of the distribution user Ub that distributes the moving image displayed on the viewing user device 10. At least one of the evaluation information may be updated. By selecting the evaluation button 33, evaluation information indicating that the moving image has been negatively evaluated may be transmitted to the server device 60. The evaluation information indicating a positive evaluation of the moving image may be referred to as positive evaluation information, and the evaluation information indicating that the negative evaluation of the moving image has been made may be referred to as negative evaluation information. When the server device 60 receives the positive evaluation information, at least one of the user evaluation information and the moving image evaluation information may be increased. When the server device 60 receives the negative evaluation information, at least one of the user evaluation information and the moving image evaluation information may be reduced.

The comment button 34 is superposed on the image 30 so as to be selectable by the user. When the comment button 34 is selected by, for example, a tap operation, a comment input window for inputting a comment is superimposed and displayed on the image 30. The viewing user can input a comment via the input mechanism of the viewing user device 10 or the distribution user device 20a. The input comment is transmitted from the viewing user device 10 and the distribution user device 20a to the server device 60. The server device 60 receives comments from the viewing user device 10, the distribution user device 20a, and other user devices, and displays the comments in the comment display area 35 in the image 30. In the comment display area 35, comments posted by each user are displayed, for example, in chronological order. The comment display area 35 occupies a part of the image 30. There is an upper limit to the number of comments that can be displayed in the comment display area 35. In the illustrated example, up to three comments can be displayed in the comment display area 35. When a comment exceeding the upper limit set in the comment display area 35 is posted, the comment with the oldest posting time is deleted from the comment display area 35 in order. Therefore, the higher the frequency of the received comments, the shorter the display time of each comment in the comment area 35. In one embodiment, a scroll bar is provided in the image 30, and the comment deleted from the comment display area 35 can be viewed by operating the scroll bar to scroll the comment.

As shown in FIG. 6b, the image 40b delivered from the server device 60 is displayed on the display of the delivery user device 20b. The image 40b displayed on the distribution user device 20b includes a character object 31 corresponding to the distribution user Ub, display instruction buttons 42a to 42c for displaying the gift received from the viewing user in the moving image, and a comment display area. 35 and are included. The image 40b displayed on the distribution user device 20b includes the same background image, character object image, and comment as the image 30 and the image 40a. On the other hand, the image 40b is different from the images 30 and 40a in that it does not include the gift button 32, the evaluation button 33, the comment button 34, and the co-star application button 36, but includes the display instruction buttons 42a to 42c. .. The display instruction buttons 42a to 42c are displayed on the image 40, for example, in response to receiving a gift from the viewing user. In the illustrated embodiment, the image 40 displays three display instruction buttons 42a to 42c. Each of the display instruction buttons 42a to 42c is displayed on the image 40 so as to be selectable by the distribution user. When any of the display instruction buttons 42a to 42c is selected by, for example, a tap operation, an operation for displaying the gift corresponding to the selected display instruction button is performed. As described above, the display instruction buttons 42a to 42c are display instruction objects for giving an instruction to display the gift on the moving image being distributed.

The invited user selection unit 61d selects an invited user to be invited to the video of the distribution user Ub from the co-starring candidate users among all the users of the video distribution system 1 for the distribution user Ub. The invited user is the destination of the invitation to co-star with the distribution user Ub.

The co-starring candidate users may be all or a part of the users of the video distribution system 1. The user of the video distribution system 1 has a user account of the video distribution system 1. The user of the video distribution system 1 uses the viewing user device 10 to distribute and view at least one of the moving images. Some users of the video distribution system 1 can only watch the video. When the viewing user device 10 used by the user of the video distribution system 1 does not have a function for acquiring motion data for video distribution (for example, a function corresponding to face motion data generation units 21a1 and 21b1). The user can only watch a moving image in the moving image distribution system 1. When the viewing user device 10 used by the user of the video distribution system 1 has a function for video distribution, the user can both view and distribute the video in the video distribution system 1. The co-starring candidate user can be, for example, a user who can distribute the moving image among all the users of the moving image distribution system 1. That is, among all the users of the video distribution system 1, users who can only watch may be excluded from the co-starring candidate users. The viewing user device 10 that does not have the function for video distribution can be provided with the function for video distribution by installing a program for realizing the function required for video distribution. Therefore, a user who can only view may be added as a co-star candidate user. When a user who only watches is invited, he / she can apply for co-starring after installing the function for video distribution.

The co-starring candidate users may be selected from all the users of the moving image distribution system 1 according to a predetermined screening criterion. As described above, whether or not the user can perform video distribution may be used as a screening criterion. In addition to this, the activity in the video distribution system 1 may be used as a screening criterion. Whether or not the user of the video distribution system 1 is active depends on the number of times the video is viewed, the frequency of video viewing, the time the video is viewed, the number of times the video is distributed, the frequency of video distribution, the time the video is distributed, and the login to the video distribution system 1. It can be evaluated by the number of times, the frequency of login to the video distribution system 1, the number of messages sent in the video distribution system 1, and various other indexes. The invited user selection unit 61d can select a user who is actively active in the video distribution system 1 from all the users of the video distribution system 1 and make the user a co-star candidate user. As screening criteria for selecting co-star candidate users, various criteria other than those specifically described herein can be applied.

The invited user selection unit 61d selects one or a plurality of invited users from the co-starring candidate users. The invited user selection unit 61d can select an invited user by using a part or all of the user information 63c. In one embodiment, the invited user selection unit 61d selects one or more invited users from the co-starring candidate users based on the log information of the distribution user Ub and the log information of each of the co-starring candidate users among the user information 63c. ..

In one embodiment of the present invention, the invited user selection unit 61d can use the viewing user information to select the invited user to be the destination of the invitation from the distribution user Ub. Specifically, the invited user selection unit 61d compares the user ID included in the viewing user information of the distribution user Ub with the user ID included in each viewing user information of the co-star candidate user, thereby and the distribution user Ub. The degree of duplication of viewing users with each of the co-star candidate users is obtained, and invited users are selected based on this degree of duplication. For example, the degree of duplication of the viewing user between the distribution user Ub and the co-starring candidate user A who is one of the co-starring candidate users is stored as viewing user information in the user information 63c in association with the user ID of the distribution user Ub. It is represented by the degree of overlap between the user ID of the viewing user and the user ID of the viewing user stored as the viewing user information in association with the user ID of the co-star candidate user A in the user information 63c. More specifically, in the user information 63c, the user IDs of 1000 viewing users are stored in association with the user IDs of the distribution user Ub, and the user IDs of 400 viewing users are the co-star candidate users. When stored as viewing user information in association with the user ID of A, the degree of duplication is 40% (100 × (400/1000) = 40%). Here is another example. In the user information 63c, the user IDs of 1000 viewing users are stored in association with the user IDs of the distribution user Ub, and the user IDs of 50 viewing users correspond to the user IDs of the co-star candidate user B. When attached and stored as viewing user information, the degree of duplication is 5% (100 × (50/1000) = 5%). The degree of duplication of viewing users between the distribution user Ub and other co-starring candidate users is also obtained. The invited user selection unit 61d obtains the degree of duplication of viewing users with the distribution user Ub for all co-starring candidate users.

In one embodiment of the present invention, the invited user selection unit 61d obtains the multiplicity of viewing users between each of the distribution user Ub and the co-starring candidate user as described above, and with the distribution user Ub among the co-starring candidate users. A user whose multiplicity of viewing users is smaller than a predetermined threshold value can be determined as an invited user. In the present specification, the threshold value regarding the degree of duplication of the viewing user may be referred to as a "first threshold value". The first threshold is, for example, 10%. The first threshold can be changed as appropriate. When the first threshold value is 10%, the multiplicity of viewing users between the distribution user Ub and the co-starring candidate user A is 40%, so the co-starring candidate user A is not selected as an invited user, and the distribution user Ub Since the degree of duplication of the viewing user with the co-star candidate user B is 5%, the co-star candidate user B is selected as the invited user. Similarly, for other co-starring candidate users, each co-starring candidate user is selected as an invited user by comparing the degree of duplication of viewing users between each co-starring candidate user and the distribution user Ub with the first threshold value. Whether or not it is determined. If the co-starring candidate user whose degree of duplication of the viewing user is smaller than the first threshold value and the distribution user Ub co-star with the distribution user Ub, the users having a small degree of duplication of the viewing user will co-star. ..

The invited user selection unit 61d selects the invited user based on the multiplicity of the viewing users in place of the multiplicity of the viewing users or in addition to the multiplicity of the viewing users, and the multiple viewing users between the distribution user Ub and each of the co-starring candidate users. You may choose. The invited user selection unit 61d compares the user ID included in the viewing user information of the distribution user Ub with the user ID included in each viewing user information of the co-starring candidate user, and thereby each of the distribution user Ub and the co-starring candidate user. The number of viewing users is obtained, and the invited users are selected based on the number of viewing users. As described above, the invited user selection unit 61d obtains a plurality of viewing users between each of the distribution user Ub and the co-starring candidate user, and among the co-starring candidate users, the multiple viewing users with the distribution user Ub. A user whose value is smaller than a predetermined threshold value can be determined as an invited user. In the present specification, the threshold value regarding the multiple viewing users may be referred to as a "second threshold value". The second threshold can be, for example, 100 people. The second threshold can be changed as appropriate. The invited user selection unit 61d can determine as an invited user a user whose degree of duplication of viewing users with the distribution user Ub and at least one of multiple multiples is smaller than a predetermined threshold value.

In this way, among the co-starring candidate users, a user whose multiplicity or multiple viewing users with the distribution user Ub is smaller than a predetermined threshold value is selected as an invited user. As a result, for the distribution user Ub and the distribution user selected as the invited user (in the above example, for the distribution user Ub and the co-starring candidate user B), the viewing user group that could not be reached until the co-starring is reached. You will be able to. For example, in the above example, when the distribution user Ub and the co-starring candidate user B co-star, the co-starring candidate user B will appear in the video distributed by the distribution user Ub, so that the co-starring candidate user B is the distribution user Ub. You can get an opportunity to reach the viewing users who watch the video. For the distribution user Ub, when the co-star candidate user B appears in his / her own video, the viewing user who often watches the video of the co-star candidate user B is the distribution user Ub in which the co-star candidate user B and the distribution user Ub co-star. It is expected to watch the video of. A viewing user who has watched the video of the co-starring candidate user B in order to encourage the viewing user who has watched the video of the co-starring candidate user B to watch the co-starring video in which the distribution user Ub and the co-starring candidate user B co-star. A notification notifying that the co-starring candidate user B will appear in the video of another distribution user (here, distribution user Ub) may be transmitted. In this way, by selecting a user having a low degree of overlap between the distribution user Ub and the viewing user and at least one of the multiple users as the invited user, both the distribution user Ub and the invited co-star candidate user (invited user) have been selected so far. It has the advantage of being able to reach the audience that could not be reached.

In another embodiment of the present invention, the invited user selection unit 61d may determine as an invited user a user whose degree of duplication of viewing users with the distribution user Ub among the co-starring candidate users is larger than a predetermined threshold value. it can. If the co-starring candidate user whose multiplicity of viewing users is larger than the first threshold value is to be co-starred with the distribution user Ub, the users having a large duplication of viewing users will co-star. In this way, by selecting a user having a high degree of overlap between the distribution user Ub and the viewing user and at least one of the multiple users as the invited user, both the distribution user Ub and the invited co-star candidate user (invited user) can view the video. It has the advantage of being able to perform with opponents who have a high degree of commonality. A co-star candidate user who has a low degree of duplication or multiple multiple viewing users with the distribution user Ub may not be favored by the viewing user who is viewing the video of the distribution user Ub. By selecting a user having a high degree of overlap between the distribution user Ub and the viewing user and at least one of the multiple as the invited user, the distribution user Ub can co-star with a partner who is easily accepted by his / her viewing user.

In another embodiment of the present invention, the invited user selection unit 61d may determine as an invited user a user whose degree of duplication of viewing users with the distribution user Ub among the co-starring candidate users is within a predetermined range. it can. That is, the invited user selection unit 61d can determine as an invited user a user whose degree of overlap of the viewing user with the distribution user Ub is between the lower limit threshold and the upper limit threshold among the co-starring candidate users. By appropriately setting the lower limit threshold value and the upper limit threshold value, it is possible to avoid determining only users whose viewer users are appropriately duplicated as invited users, or co-starring only with a partner whose viewer layer overlap is very small. ..

In another embodiment of the present invention, the invited user selection unit 61d can use the co-starring number information to select an invited user to be sent an invitation from the distribution user Ub. Specifically, the invited user selection unit 61d obtains the difference between the number of co-stars of the distribution user Ub and the number of co-stars of each of the co-star candidate users, and selects the invited user based on the difference in the number of co-stars. For example, the difference between the number of co-stars of the distribution user Ub and the number of co-stars of the co-star candidate user A who is one of the co-star candidate users is stored as the co-star count information in the user information 63c in association with the user ID of the distribution user Ub. This is the difference between the number of co-stars and the number of co-stars stored as co-star count information in association with the user ID of the co-star candidate user A in the user information 63c.

In one embodiment of the present invention, the invited user selection unit 61d obtains the difference in the number of co-stars between each of the distribution user Ub and the co-starring candidate user as described above, and among the co-starring candidate users, the distribution user Ub. A user whose difference in the number of co-stars is larger than a predetermined threshold value can be determined as an invited user. In the present specification, the threshold value regarding the number of co-stars may be referred to as a "third threshold value". The third threshold is, for example, 10 times. The third threshold can be changed as appropriate. When the third threshold value is 10 times, a co-starring candidate user whose difference from the number of co-starring times of the distribution user Ub is larger than 10 times is selected as an invited user. If a co-star candidate user having a large difference in the number of co-stars and the distribution user Ub co-star with the distribution user Ub, the users having a large difference in the number of co-stars will co-star.

In this way, among the co-starring candidate users, a user having a large difference in the number of co-starring with the distribution user Ub is selected as an invited user. If the number of co-stars of the distribution user Ub is larger than the number of co-stars of the invited user, the invited user will be invited by the user who is proficient in co-starring in the video, so that it will be easier to apply for co-starring according to the invitation. .. On the contrary, when the number of co-stars of the invited user is larger than the number of co-stars of the distribution user Ub, the distribution user Ub can co-star with a user who is proficient in co-starring in the moving image.

In another embodiment of the present invention, the invited user selection unit 61d can use the attribute information to select the invited user to whom the invitation from the distribution user Ub is sent. Specifically, the invited user selection unit 61d can compare the attribute information of the distribution user Ub with the attribute information of each of the co-star candidate users, and select the invited user based on the comparison result. For example, a co-star candidate user who shares at least a part of the information registered as attribute information can be selected as an invited user. By selecting the invited user based on the attribute information in this way, it is possible to select the co-star candidate user who has a profile highly common to the distribution user Ub as the invited user. As a result, users who have a high degree of commonality in terms of profile can co-star in a video. By co-starring users who have a high degree of commonality in terms of profile, it can be expected that conversations between co-stars will progress smoothly in the video. On the contrary, a co-star candidate user having a profile having a low commonality with the distribution user Ub can be selected as an invited user. As a result, users who have little commonality in terms of profile can co-star in a moving image. By co-starring users who have low commonality in terms of profile, it can be expected that co-stars will interact with each other with a sense of surprise and tension.

In another embodiment of the present invention, the invited user selection unit 61d can use social information to select an invited user to whom an invitation is sent from the distribution user Ub. Specifically, the invited user selection unit 61d can compare the social information of the distribution user Ub with the social information of each of the co-star candidate users, and select the invited user based on the comparison result. For example, the invited user selection unit 61d can select a co-star candidate user who has a friend in common with the distribution user Ub as the invited user based on the friend information in the social information. The invited user selection unit 61d can select a co-star candidate user who has a predetermined number or more (for example, 10 or more) of common friends with the distribution user Ub as the invited user. On the contrary, the invited user selection unit 61d can select a co-star candidate user who does not have a friend in common with the distribution user Ub as an invited user. The invited user selection unit 61d can select a co-star candidate user whose number of friends in common with the distribution user Ub is a predetermined number (for example, 3) or less as an invited user.

As described above, the invited user selection unit 61d uses at least one of the viewing user information, the number of co-starring information, the attribute information, and the social information to select the invited user who is the destination of the invitation from the distribution user Ub. Can be selected. The invited user selection unit 61d can select an invited user by appropriately combining viewing user information, co-starring number information, attribute information, and social information. For example, the invited user selection unit 61d uses both the viewing user information and the number of co-starring information, and the co-starring candidate user whose degree of duplication of viewing users is smaller than the first threshold value and the difference in the number of co-starring times is larger than the third threshold value. Can be selected as an invited user.

The invited user selection unit 61d may select the invited user when the distribution user Ub starts distribution of the video, or may receive an invitation request from the invitation processing request unit 21b2 of the distribution user device 20b. Invited users may be selected.

The invitation processing unit 61e invites the invited users selected by the invited user selection unit 61d to one or more distribution user devices included in the video distribution system 1 based on the invitation request from the invitation request unit 21b2. Send. As described above, this invitation is a notification for inviting another distribution user to the video distributed by the distribution user Ub. The invitation request transmitted from the distribution user device 20b will be further described with reference to FIG. 7. FIG. 7 is a diagram illustrating a window for setting an invitation request displayed on the distribution user device 20b. The distribution user device 20b displays the setting window 41 before the start of distribution of the moving image or after the start of distribution of the moving image. The setting window 41 may be displayed according to the user's operation, or may be displayed at a predetermined timing before the start of the moving image distribution or after the start of the moving image distribution without the user's operation.

In the illustrated embodiment, the setting window 41 includes a switch 41a, a stepper 41b, and a password setting area 41c. The switch 41a is a switch for switching whether or not to transmit an invitation. The switch 41a is switched on or off according to the operation of the user. When the switch 41a is turned on, the setting is switched so that the invitation request is transmitted to the server device 60. When the switch 41a is turned off, the invitation request is not transmitted to the server device 60. For example, an invitation request is transmitted to the server device 60 when the window 41 is closed after the switch 41a is turned on.

The stepper 41b is an operation unit for increasing or decreasing the numerical value input according to the operation of the user. In the illustrated embodiment, the stepper 41b can increase or decrease the number of co-stars who can co-star in the moving image to be distributed or the moving image being distributed. In the example of FIG. 7, 10 people are set as the number of people who can co-star. The number of people set when "-" is selected in the stepper 41b is reduced from 10 to, for example, 9, and the number of people set when "+" is selected in the stepper 41b is increased from 10 to, for example, 11. Increase to. In one embodiment, the number of co-stars may mean the maximum number of users who co-star at the same time in the video to be distributed. In this embodiment, if the number of co-stars is set to 10, 10 users can co-star in the moving image through the character at the same time. In another embodiment, the number of people who can co-star at the same time is set to a smaller number (for example, two people) than the maximum number of co-stars set. In this case, the upper limit of the number of co-stars means the upper limit of the number of users who can co-star within the distribution time. For example, if the number of people who can co-star in a video is set to 2 and the upper limit of the number of co-stars is set to 10, the appearance order is set for 10 guest users, and the guest users follow this appearance order. Will co-star with the host user one by one. The invited user selection unit 61d may increase or decrease the number of invited users to be selected according to the set upper limit of the number of co-stars. More specifically, the invited user selection unit 61d affects the first threshold value, the second threshold value, the third threshold value, and the number of other selected invited users according to the set upper limit of the number of co-stars. The given parameters may be adjusted.

A co-star password provided to a guest user who wishes to co-star is set in the password setting area 41c. This co-star password is, for example, a 4-digit number string. The distribution user Ub can perform co-starring only with the specific distribution user by notifying the co-starring password only to the specific distribution user among the distribution users using the distribution system 1. In other words, the distribution user Ub can avoid co-starring with the distribution user who has not notified the co-starring password. When notifying the co-star password only to a specific distribution user, the distribution user Ub can specify the specific distribution user by inputting the user ID of the distribution user to be notified. There are no particular restrictions on how to specify a specific distribution user to notify the co-star password. If the password input is not required when applying for co-starring, the password setting area 41c is omitted.

The invitation request unit 21b2 generates an invitation request based on the settings determined through the setting window 41 and other input interfaces as necessary, and transmits the invitation request to the server device 60. The invitation request also includes the user ID of the distribution user Ub. The invitation request may include the number of co-stars, the co-star password, and other information needed to perform the invitation.

The invitation processing unit 61e generates an invitation based on the invitation request from the invitation request unit 21b2, and transmits the generated invitation to the distribution user device of the invited user selected by the invited user selection unit 61d. If the invitation request includes a co-star password, the invitation processing unit 61e may notify the invited user of the co-star password.

When the invitation processing unit 61e receives the invitation request from the distribution user Ub, the invitation processing unit 61e refers to the user information 63c stored in the storage 63 and generates the host user information of the distribution user Ub. In one embodiment, the host user information of the distribution user (distribution user Ub) who made the invitation request is the user evaluation information stored in the user information 63c in association with the user account information of the distribution user (distribution user Ub). , Video evaluation information, and at least a part of the number of viewers information, or generated based on this information. In other words, the host user information of the distribution user who made the invitation request is at least one of the user evaluation information, the video evaluation information, and the number of viewers information stored in association with the user account information of the distribution user. It may be a score generated based on this information. The host user information is preferably an index that can be referred to for determining whether or not the invited distribution user applies for co-starring with the distribution user Ub. For example, the profile of the distribution user Ub as a host user. It is desirable that it is an index to represent.

The invitation processing unit 61e can transmit the host user information of the distribution user Ub to the distribution user Ua and other distribution users in association with the invitation for inviting the distribution user Ub to co-star. As a result, the distribution user who receives the invitation from the distribution user Ub can access the host user information of the distribution user Ub. In other words, the host user information of the distribution user Ub is associated with the invitation so that it can be presented to the distribution user who received the invitation from the distribution user Ub. In one embodiment, the host user information is transmitted to the distribution user as part of the invitation. The host user information may be sent to the distribution user along with the invitation. In another embodiment, the host user information is stored in the server device 60, and the invitation may include a link to the host user information stored in the server device 60.

Next, the processing of the invited user in the distribution user device will be described with reference to FIG. In this specification, it is assumed that the distribution user Ua is selected as the invited user by the invited user selection unit 61d. FIG. 8 shows an example of displaying an invitation in the distribution user device 20a of the distribution user Ua who has received the invitation from the distribution user Ub. Upon receiving the invitation from the distribution user Ub, the invitation presentation unit 21a2 of the distribution user device 20a displays the window 37 on the display 23a of the distribution user device 20a as shown in the figure. Window 37 contains the string "Invited by Ub" to indicate that the invitation was received. As a result, the distribution user Ua can know that the invitation from the distribution user Ub has been received. In addition to the character string, the window 37 can include a display area 37a, a co-star application button 37b, and a co-star decline button 37c.

The invitation presentation unit 21a2 displays the host user information of the distribution user Ub in the display area 37a. As described above, the host user information in one embodiment is an index representing the profile of the distribution user Ub as a host user. The host user information may be, for example, viewer number information. When the number of viewing users of the video distributed by the distribution user Ub is large, the distribution user Ua may be able to acquire a large number of viewing users by co-starring with the distribution user Ub. The host user information may be user evaluation information. The high user evaluation information of the distribution user Ub means that the distribution user Ub has gained a high reputation from other users. Therefore, when the user evaluation information of the distribution user Ub is high, the distribution user Ua may be able to obtain a high evaluation by co-starring with the distribution user Ub. The host user information may be video evaluation information. The high video evaluation information of the distribution user Ub means that the video distributed by the distribution user Ub has gained a high reputation. Therefore, when the video evaluation information of the distribution user Ub is high, the distribution user Ua may be able to obtain a high evaluation by appearing in the video of the distribution user Ub.

The host user information may be a score calculated by a predetermined algorithm based on a part or all of the number of viewers information, the user evaluation information, and the video evaluation information. For example, since many distribution users are considered to aim to acquire more viewing users, the number of viewers information may be more important to guest users than other information contained in the user information. Therefore, for the viewer number information, the user evaluation information, and the video evaluation information, it is possible to calculate a weighted average in which the viewer number information is weighted more and use the score represented by this weighted average as the host user information. it can. The method of calculating the score indicating the host user information is not limited to that explicitly described herein.

As described above, the viewer number information, user evaluation information, and video evaluation information of the distribution user Ub, and the score calculated based on these information, are the attractiveness of the distribution user Ub as a host user or as a co-star. Can be an indicator of. By displaying such host user information in the display area 37a, it is possible to convey information that can be referred to when deciding whether or not to co-star with the distribution user Ub who sent the invitation to the distribution user Ua who is the invited user. .. The distribution user Ua can determine whether or not to perform co-starring with the distribution user Ub based on the host user information.

The co-starring application button 37b included in the window 37 is an operation button for transmitting a co-starring application for applying for co-starring with the distribution user Ub in the video distributed by the distribution user Ub. The co-starring application is transmitted to the server device 60 by selecting the co-starring application button 37b, and the transmitted co-starring application is accepted by the server device 60. The server device 60 can accept not only co-starring applications from distribution user Ua but also co-starring applications from various distribution users. If neither the co-star application button 37b nor the co-star decline button 37c is selected within a predetermined time after the window 37 is displayed, the window 37 may be deleted from the screen. As described above, the co-star application button 36 may be displayed on the moving image 40a displayed on the distribution user device 20a. Therefore, the window 37 does not have to include the co-star application button 37b. If the window 37 does not include the co-star application button 37b, the distribution user Ua can select the co-star application button 36 when applying for co-starring with the distribution user Ub.

In the illustrated embodiment, the co-star application button 36 is displayed before the window 37 is displayed. In this case, even before receiving the invitation, the distribution user Ua can apply for co-starring with the distribution user Ub by selecting the co-starring application button 36. In this way, when accepting co-starring applications from distribution users who have not received an invitation, there is a possibility that an excessive number of co-starring applications will be made. In particular, when the distribution user Ub is a popular distribution user, a large number of co-starring applications may be made. Therefore, in another embodiment of the present invention, the co-star application button 36 may be displayed only on the distribution user device of the distribution user who received the invitation after receiving the invitation. When an invitation is received, the co-star application button 37b is displayed in the window 37, but the co-star application button 36 may be displayed in the image 40a after the window 37 disappears from the image. As a result, the co-starring application can be accepted only from the invited user who received the invitation.

In one embodiment of the present invention, the co-star application button 36 may be displayed on the image 40a regardless of whether or not the invitation has been received. In this case, the input of the co-star password may be requested when the co-star application button 36 is selected, and the co-star request may be transmitted to the server device 60 only when the co-star password is authenticated. The distribution user Ub can control the number of co-starring applications by notifying the co-starring password only to the users who approve the co-starring application. The notification of the co-star password is sent to the user through the messaging function used in the video distribution system 1, the messaging function different from the video distribution system 1 (for example, LINE provided by LINE Corporation), and channels other than these. Can be notified. In this way, the co-star password can be transmitted to the user who is watching the video distributed by the related user Ub or other users without associating with the invitation from the distribution user Ub.

When the co-starring application processing unit 61f receives a co-starring application from a certain user (for example, distribution user Ua), the co-starring application processing unit 61f determines whether or not to allow the co-starring application of the user. The co-starring application processing unit 61f may determine whether or not to allow co-starring between the distribution user Ua and the distribution user Ub based on at least a part of the user information of the distribution user Ua who applied for the co-starring. For example, when the user evaluation point of the distribution user Ua who applied for co-starring is larger than a predetermined threshold value, co-starring with the distribution user Ub of the distribution user Ua is permitted, and when the user evaluation point is less than the threshold value, the distribution user of the distribution user Ua Co-starring with Ub may be refused. There are no particular restrictions on this criterion. The invited user selection unit 61d is configured to select a user who is desirable as a co-starring partner of the distribution user Ub as an invited user, but even if an undesired user as a co-starring partner is selected as an invited user. By determining whether or not co-starring is possible by the co-starring application processing unit 61f, it is possible to avoid co-starring with an undesired co-starring partner.

When the co-starring application from the distribution user Ua is permitted, the co-starring application processing unit 61f generates a co-starring video in which the distribution user Ua and the distribution user Ub co-star based on the co-starring application. In order to generate the co-starring moving image, the co-starring application processing unit 61f acquires the face motion data and the voice data of the distribution user Ua from the distribution user Ua. The face motion data of the distribution user Ua may be transmitted from the distribution user device 20a to the server device 60 together with the co-star application, or the server device 20a responds to a request from the server device 60 after the co-star application is approved. It may be transmitted to the device 60. When the body movement of the distribution user Ua is also expressed as an animation, the body motion data may be provided to the server device 60 together with the face motion data of the distribution user Ua. When the face motion data cannot be acquired from the distribution user Ua, the co-star application processing unit 61f may acquire only the voice data from the distribution user Ua. For example, when the distribution user device 20a used by the distribution user Ua does not have the function of the face motion data generation unit 21a1 or other functions for video distribution, the function is disabled, and other than these. In the case of, the co-star application processing unit 61f may acquire the voice data without acquiring the face motion data (and the body motion data) from the distribution user Ua.

In one embodiment, the co-star application processing unit 61f adds an animation of the character object of the distribution user Ua to the video being distributed including the character object 31 of the distribution user Ub based on the face motion data of the distribution user Ua. Then, generate a co-starring video. The animation of the character object of the distribution user Ua may be generated by the animation generation unit 61a based on the face motion data of the distribution user Ua. The animation of the character object of the distribution user Ua may be generated by applying the face motion data of the distribution user Ua to the model data for the distribution user Ua included in the model data 63a. For example, the co-star application processing unit 61f generates a layer including an animation of the character object of the distribution user Ua, and superimposes this layer on the moving image including the character object 31 of the distribution user Ub to obtain the character object of the distribution user Ua and the character object of the distribution user Ua. It is possible to generate a co-starring moving image including the character object 31 of the distribution user Ub. By generating a co-starring video including the character object of the distribution user Ua and the character object 31 of the distribution user Ub, the distribution user Ua and the distribution user Ub are using the video distribution system 1 from points apart from each other. However, it is possible to virtually co-star in the co-starring video. When the co-star application processing unit 61f acquires the voice data without acquiring the face motion data (and body motion data) from the distribution user Ua, the co-star application processing unit 61f acquires the video including the character object 31 of the distribution user Ub from the distribution user Ua. By superimposing the voice generated based on the generated voice data, it is possible to generate a co-starring moving image including the character object 31 of the distribution user Ub and the voice of the distribution user Ua. The co-star application processing unit 61f is based on the audio data acquired from the distribution user Ua in the video including the character object 31 of the distribution user Ub even when the model data for the distribution user Ua is not set as the model data 63a. By superimposing the generated voice, it is possible to generate a co-starring moving image including the character object 31 of the distribution user Ub and the voice of the distribution user Ua. In this way, the distribution user Ua can co-star with the distribution user Ub by his / her own voice.

When the co-starring application processing unit 61f cannot acquire the face motion data from the distribution user Ua, the co-starring video including the voice of the distribution user Ua and the character object 31 of the distribution user Ub is distributed, and then the face motion data is acquired from the distribution user Ua. By generating the character object of the distribution user Ua based on the face motion data of the distribution user Ua at the same timing, it is possible to generate the co-starring video including the character object of the distribution user Ua and the character object 31 of the distribution user Ub. .. In this way, the co-starring application processing unit 61f switches the co-starring video including the voice of the distribution user Ua and the character object 31 of the distribution user Ub to the co-starring video including the character object of the distribution user Ua and the character object 31 of the distribution user Ub. be able to. On the contrary, the co-starring application processing unit 61f displays the co-starring video including the character object of the distribution user Ua and the character object 31 of the distribution user Ub, and the co-starring video including the voice of the distribution user Ua and the character object 31 of the distribution user Ub. Can be switched to. In this way, a co-starring video in which voice co-starring is performed (sometimes referred to as "voice co-starring video") and a co-starring video in which character objects are co-starring (sometimes referred to as "character co-starring video"). ) May be switched alternately.

The generated co-starring moving image is distributed by the moving image distribution unit 61c. The co-starring moving image may be created by the distribution user device 20a. When the co-starring moving image is generated by the distribution user device 20a, the co-starring moving image is transmitted from the distribution user device 20a to the server device 60 and distributed by the moving image distribution unit 61c of the server device 60.

9 and 10a to 10b show a display example of the co-starring moving image distributed from the moving image distribution unit 61c. In these figures, since the co-starring application is permitted from the distribution user Ua to the distribution user Ub, it is assumed that the co-starring video including the character object 131 of the distribution user Ua and the character object 31 of the distribution user Ub is distributed. There is.

As shown in FIG. 9, the display of the viewing user device 10 displays the image 230 of the co-starring moving image distributed from the server device 60. The image 230 of the co-starring moving image displayed on the viewing user device 10 includes the character object 131 of the distribution user Ua in addition to the character object 31 of the distribution user Ub. As described above, the character object 131 of the distribution user Ua is generated by the animation generation unit 61a or the co-star application processing unit 61f. The image 230 of the co-starring video includes a gift button 32, an evaluation button 33, a comment button 34, and a comment display area 35, similar to the original distribution image shown in FIG. In addition to these, the image 230 of the co-starring moving image may include guest evaluation buttons 133a and 133b. The guest evaluation button 133a is a button for transmitting positive evaluation information indicating a positive evaluation to the guest user (in the illustrated example, the distribution user Ua is the guest user) to the server device 60, and is a guest evaluation. The button 133b is a button for transmitting negative evaluation information indicating a negative evaluation to the guest user to the server device 60. When the guest evaluation button 133a is selected by the viewing user who is watching the video, guest evaluation information indicating that the guest user has been positively evaluated is transmitted to the server device 60, and the guest evaluation button 133b is selected. Then, guest evaluation information indicating that the guest user has been positively evaluated may be transmitted to the server device 60. Although not shown, one or more host evaluation buttons for evaluating the host user may be displayed together with the co-starring video. When the host evaluation button is selected by the viewing user who is watching the video, host evaluation information indicating that the host user (delivery user Ub) has been positively or negatively evaluated is transmitted to the server device 60. May be done.

As shown in the figure, the image 230 of the co-starring moving image is a horizontally long image. The co-star application processing unit 61f or the video distribution unit 61c may distribute the co-star video as a horizontally long video. As a result, the image 230 of the co-starring moving image is displayed as a horizontally long image on the viewing user device 10. In one embodiment, even if the original moving image (image) is vertically long as shown in FIG. 5, the co-starring moving image is converted to horizontally long and distributed. Since the co-starring video includes the character objects of the two distribution users, it is easy to display the character objects of the two people without duplication by making the image horizontally long. For example, in a co-starring video, the left half is the area allocated to the character object of the original distribution user (host user) from the viewpoint of the viewing user, and the right half is the character of the distribution user (guest user) who applied for co-starring. It may be an area allocated to an object. The allocation of the area to each distribution user may be arbitrarily determined so that the character objects do not overlap with each other.

As shown in FIG. 10a, the image 330 of the co-starring moving image distributed from the server device 60 is displayed on the distribution user device 20a of the distribution user Ua. The co-starring moving image image 330 displayed on the distribution user device 20a includes the same background image, character object image, and comment as the co-starring moving image image 230 displayed on the viewing user device 10. On the other hand, the image 330 of the co-starring video is different from the image 230 in that it does not include the gift button 32, the evaluation button 33, the comment button 34, and the co-starring application button 36, but includes the display instruction buttons 42a to 42c. ..

As shown in FIG. 10b, the image 430 of the co-starring moving image distributed from the server device 60 is displayed on the display of the distribution user device 20b. The image 430 of the co-starring video displayed on the distribution user device 20b has the same background image, character objects 31, 131, comments 35, and display as the image 330 displayed on the distribution user device 20a of the distribution user Ua of the co-starring partner. The instruction buttons 42a to 42c are included. On the other hand, in the image 430, a co-star end button 45 for ending the co-star is displayed. In one embodiment, the co-starring end button 45 is not only the image 430 of the co-starring video in the distribution user device 20b of the distribution user Ub who received the co-starring application, but also the co-starring in the distribution user device 20b of the distribution user Ua who applied for the co-starring. It may be displayed on the image 330 of the moving image. When the co-star end button 45 is selected, a process for ending the co-star with the distribution user Ua is performed in the co-star video. For example, in response to the selection of the co-starring end button 45 in the distribution user device 20b, the distribution user device 20b transmits a co-starring end instruction to the server device 60. The distribution user Ub can set the distribution user Ua, which is a guest user, as a co-star prohibition user while playing the co-star video. For example, when the distribution user Ua performs an undesired action or behavior in the co-starring video, the distribution user Ua can be set as the co-starring prohibited user. The setting of the distribution user Ua as a co-star prohibition user may be performed by recording the user ID of the distribution user Ub in the appearance prohibition information of the user information of the distribution user Ua. For example, when the server device 60 receives the co-starring end instruction from the distribution user device 20b, the server device 60 can automatically register the distribution user Ua as a co-star prohibition user in the user information of the distribution user Ub. The distribution user Ub may set the distribution user Ua as a prohibited user other than when playing back the co-starring video. For example, the distribution user Ua may be set as a prohibited user in response to the confirmation of the posting of an unwanted message by the distribution user Ua in the messaging service provided by the video distribution system 1. Contrary to the above example, when the distribution user Ub performs an undesired action or behavior, the host user is set as the co-star prohibition user according to the selection of the co-star end button 45 on the distribution user device 20a. May be good.

A warning button (not shown) for giving a warning to the guest user may be displayed on the image 430 of the co-starring moving image in the distribution user device 20b of the distribution user Ub who is the host user. This warning button may be displayed on the image 330 of the co-starring moving image in the distribution user device 20a of the distribution user Ua who is a guest user. Unlike the co-star end button 45, the warning button does not end the co-star immediately, but when the guest user takes an undesired action for the host user or the host user takes an undesired action by the guest user. It is expected to be selected in some cases. When the warning button is selected in the distribution user device of the host user (for example, the distribution user device 20b of the distribution user Ub), the distribution user device 20b transmits a warning instruction to the server device 60. When the warning button is selected in the distribution user device of the host user, the host user gives a warning in the image 330 of the co-starring video displayed on the distribution user device of the guest user (for example, the distribution user device 20a of the distribution user Ua). Warning information indicating that may be displayed. The warning information may be displayed on the image 230 in the viewing user device 10. The co-starring moving image including the warning information may be generated in the server device 60. By displaying the warning information on the image 230 of the viewing user, it is possible to indicate to the viewing user that the host user is responding to the undesired behavior of the guest user. The server device 60 counts the number of times a warning instruction is given from a certain host user to a certain guest user, and when the number of warning instructions reaches a predetermined number of times (for example, three times), the host user and the guest user. You may perform the process to end the co-starring with. The process for ending the co-starring based on the warning instruction of the predetermined number of times or more may be the same process as the process for ending the co-starring based on the above-mentioned co-starring end instruction.

The co-star application processing unit 61f may issue a video ID that identifies the created co-star video. The co-starring moving image information related to the co-starring moving image can be stored in the storage 63 in association with the moving image ID. As described above, the co-starring time information of the co-starring moving image may be updated in association with the moving image ID of the co-starring moving image being distributed. The co-starring time information may be updated based on the monitoring result of monitoring the distribution time of the co-starring moving image in the moving image distribution unit 61c.

Of the co-starring video information, the guest user evaluation information includes positive evaluation information indicating a positive evaluation to the distribution user Ua who is a guest user from the viewing user device 10 and negative evaluation information indicating a negative evaluation to the distribution user Ua. It may be updated based on. For example, when the server device 60 receives the positive evaluation information indicating the positive evaluation to the distribution user Ua from the viewing user device 10, the guest user evaluation points may be increased, and the server device 60 may increase the guest user evaluation points, which is negative to the distribution user Ua. When the negative evaluation information indicating the evaluation is received, the guest user evaluation points may be reduced. If the viewing user stops viewing the co-starring video in the middle, the viewing user may not be satisfied with the co-starring video. Therefore, when the viewing user stops viewing the co-starring video in the middle, the guest user evaluation points of the guest user may be reduced as if the guest user had a negative evaluation. At least one of the positive and negative evaluation information may be updated to decrease over time. For example, even if the distribution user Ua has 100 points of positive evaluation information at a certain time, the positive evaluation information may be updated so as to approach zero with the passage of time. When the negative evaluation information for a certain user exceeds a predetermined value, the co-starring with another user may be prohibited for the user. For example, in the image displayed on the distribution user device of the user whose negative evaluation information exceeds the predetermined value, the process of not displaying the co-star application button 36 may be performed.

The co-starring end processing unit 61g is a guest user distribution user Ua and a host user distribution user Ua when the co-starring end condition for terminating the co-starring between the guest user distribution user Ua and the host user distribution user Ub is satisfied. Performs processing for ending the co-starring with the user Ub. In one embodiment, when the co-starring end processing unit 61g receives the co-starring end instruction from the distribution user device 20b of the distribution user Ub who is the host user, it determines that the co-starring end condition is satisfied and ends the distribution of the co-starring moving image. Is processed. For example, when the co-starring end processing unit 61g receives the co-starring end instruction, the animation generation of the character object 131 of the distribution user Ua is stopped, and the character object 31 of the distribution user Ub is not included in the character object 131 of the distribution user Ua. Generate a video that contains. In other words, the character object 131 of the distribution user Ua, which is the guest user, is excluded from the video to be distributed. By eliminating the character object 131 of the distribution user Ua, which is the guest user, the co-starring of the distribution user Ua and the distribution user Ub ends. After the co-starring is completed, the distribution of the moving image including the character object 31 without including the character object 131 may be continued. The moving image delivered after the end of the co-starring may be generated as a vertically long moving image as shown in FIG. That is, the orientation of the moving image may be changed according to the end of the co-starring. In one embodiment, the orientation of the moving image may be changed from landscape to portrait depending on the end of the co-starring. In another embodiment, the distribution of the moving image by the distribution user Ub, which is the host user, may be terminated in response to the termination of the co-starring. In one embodiment, if a co-starring application from another user has already been received when the co-starring with the distribution user Ub is completed, the co-starring application processing unit 61f will perform the co-starring of the other user based on the co-starring application. It may be determined whether or not it is possible.

In one embodiment, the co-starring end processing unit 61g determines whether or not the character object 131 of the distribution user Ua, which is a guest user, is in the inactive state, and if it is determined that the character object 131 is in the inactive state, the co-starring end processing unit 61g. It is determined that the condition is satisfied. In one embodiment, whether or not the character object 131 of the distribution user Ua is in the inactive state is determined by at least one of face motion data, body motion data, and voice data received from the distribution user device 20a of the distribution user Ua. Judgment is based on. Since the face motion data, the body motion data, and the voice data are all data indicating the movement of the distribution user, they may be collectively referred to as "motion data" in the present specification. Whether or not the character object 131 of the distribution user Ua is in the inactive state is determined based on the motion data, that is, based on at least one of face motion data, body motion data, and voice data. For example, when the face motion data is not input from the distribution user device 20a of the distribution user Ua for a certain period of time, the facial expression of the character object 131 of the distribution user Ua does not move for a certain period of time in the co-starring video, so that the character object 131 is inactive. It may be determined that it is in a state. If the body motion data is not input from the distribution user device 20a of the distribution user Ua for a certain period of time, the body movement of the character object 131 of the distribution user Ua does not move for the certain period of time in the co-starring video, so that the character object 131 is inactive. It may be determined that it is in a state. When there is no input of audio data from the distribution user device 20a of the distribution user Ua for a certain period of time, the character object 131 of the distribution user Ua becomes silent for the certain period of time in the co-starring video, so that the character object 131 is in the inactive state. It may be determined.

In one embodiment, the co-starring end processing unit 61g ends the co-starring by excluding the character object 131 of the distribution user Ua, which is a guest user, from the moving image according to the co-starring moving image information of the co-starring moving image being distributed. For example, when the guest user evaluation information is a guest user evaluation point, the co-star end processing unit 61g excludes the character object 131 of the distribution user Ua from the moving image when the guest user evaluation point becomes smaller than a predetermined threshold value. By doing so, the co-starring with the distribution user Ua can be terminated. The guest user evaluation point becomes smaller as the negative evaluation information for the distribution user Ua, which is the guest user, is received from the viewing user. Therefore, by determining whether or not to end the co-starring with the distribution user Ua based on the guest user evaluation points, it is possible to avoid co-starring with a user having a low evaluation from the viewing user for a long period of time.

Next, with reference to FIG. 11, a moving image distribution process according to one aspect will be described. FIG. 11 is a flow chart showing the flow of the moving image distribution process in one embodiment. In the moving image distribution process described with reference to FIG. 11, it is assumed that the moving image of the distribution user Ub is distributed from the server device 60. That is, it is assumed that the moving image generated based on the face motion data of the distribution user Ub acquired by using the distribution user device 20b is distributed from the server device 60.

First, in step S11, face motion data, which is a digital representation of the facial movement (facial expression) of the distribution user Ub, is generated. The face motion data is generated, for example, by the face motion data generation unit 121b of the distribution user device 20b. In the distribution user device 20b, voice data may be generated based on voice input from distribution users Ua and Ub. The generated face motion data and voice data are transmitted to the server device 60.

Next, in step S12, the face motion data from the distribution user device 20b is applied to the model data for the distribution user Ub to generate an animation of the character object 31 that moves in synchronization with the movement of the facial expression of the distribution user Ub. Will be done. This animation is generated, for example, by the animation generation unit 61a described above.

Next, in step S13, a moving image including the animation of the character object 31 of the distribution user Ub is generated. The voice of the distribution user Ub may be synthesized with this moving image. The animation of the character object 31 is displayed superimposed on the background image. This moving image is generated, for example, by the moving image generation unit 61b described above.

Next, the process proceeds to step S14, and the moving image generated in step S13 is distributed. This moving image is distributed to the viewing user device 10 and other viewing user devices and distribution user devices via the network 50. When the delivered moving image is played back on the viewing user device 10, for example, an image of the moving image as shown in FIG. 5 is displayed on the viewing user device 10. The video is continuously distributed over a predetermined distribution period. The video distribution period can be set to, for example, 30 seconds, 1 minute, 5 minutes, 10 minutes, 30 minutes, 60 minutes, 120 minutes, and any other time. The moving image is distributed, for example, by the moving image distribution unit 61c described above.

Next, the process proceeds to step S15, and it is determined whether or not the termination condition for terminating the distribution of the moving image is satisfied. The end condition is, for example, that the end time of the distribution has been reached, that the distribution user Ub has performed an operation for ending the distribution on the distribution user device 20b, or a condition other than these. If the end condition is not satisfied, the processes of steps S11 to S14 are repeatedly executed, and a video including an animation synchronized with the movement of the distribution user Ub, or a co-starring video when co-starring with the distribution user Ua continues. Delivery will continue. If it is determined that the end condition for the video is satisfied, the distribution process of the video is terminated.

Next, with reference to FIG. 12, a process of presenting an invitation to an invited user in one embodiment will be described. FIG. 12 is a flow chart showing a flow of a process of inviting a distribution user who distributes a moving image to another distribution user to co-star in the moving image in one embodiment. In the distribution process of the co-starring video described with reference to FIG. 12, the distribution user Ub may invite the distribution user Ua who is viewing the video including the character object of the distribution user Ub to co-star. It is supposed. The invitation process for co-starring may be performed in parallel with the moving image distribution process shown in FIG. 11, or may be performed before the start of the moving image distribution process shown in FIG.

First, in step S21, an invitation request is transmitted to the server device 60 before or during distribution of the moving image including the character object of the distribution user Ub. The invitation request is transmitted from the distribution user device 20b to the server device 60 in response to the operation of the distribution user Ub. The invitation request transmission process is performed by, for example, the invitation request unit 21b2.

Next, in step S22, one or more invited users are selected. The invited user is selected from among the co-starring candidate users based on the log information of the distribution user Ub and the log information of each of the co-starring candidate users. The selection of the invited user may be performed using at least one of the viewing user information, the number of co-starring information, the attribute information, and the social information. Invited users are selected, for example, by the above-mentioned invited user selection unit 61d. The step S22 for selecting the invited user may be performed before the step S21.

Next, in step S23, an invitation to invite the distribution user Ub to co-star in the video is transmitted to one or more distribution user devices including the distribution user device 20a of the distribution user Ua. In addition, the host user information of the distribution user Ub is transmitted in association with this invitation. The host user information of the distribution user Ub is generated based on the invitation request from the distribution user Ub. As described above, the host user information is generated by referring to at least one of the user information 63c and the co-starring moving image information 63d stored in the storage 63. The host user information generation process is performed by, for example, the invitation processing unit 61e described above. The invitation and the transmission process of the host user information are performed by, for example, the invitation processing unit 61e described above.

Next, in step S24, the invitation is received by the distribution user device 20a of the distribution user Ua. In the distribution user device 20a, the character string "Invited by Ub" indicating that the invitation has been received from the distribution user Ub and the host user information of the distribution user Ub are displayed. As described above, the host user information is information generated based on the user information 63c, and is preferably an index showing the attractiveness of the distribution user Ub as a co-star. The host user information is displayed by, for example, the invitation presentation unit 21a2 described above. The distribution user Ua can determine whether or not to apply for co-starring based on the host user information of the distribution user Ub displayed on the distribution user device 20a. The distribution user Ua can apply for co-starring by selecting the co-starring application button 37b displayed on the distribution user device 20a together with the host user information.

When a co-starring application is made, the co-starring video is subsequently distributed. The distribution process of the co-starring moving image in one embodiment will be described with reference to FIG. FIG. 13 is a flow chart showing a flow of processing for distributing a co-starring moving image in one embodiment. In the distribution process of the co-starring video described with reference to FIG. 13, it is assumed that the distribution user Ua who is viewing the video including the character object of the distribution user Ub has applied for co-starring to the distribution user Ub. ing. The co-starring moving image distribution process is performed in parallel with the moving image distribution process shown in FIG.

First, in step S31, it is determined whether or not a co-star application has been made by a user other than the distribution user Ub during distribution of the moving image including the character object of the distribution user Ub. The co-starring application is made, for example, by the distribution user Ua. As described above, the distribution user Ua can apply for co-starring by selecting the co-starring application button 37b displayed on the distribution user device 20a after receiving the invitation. The co-star application may be made by selecting the co-star application button 36. When the co-starring application is made by the distribution user Ua, the process proceeds to step S32. The co-starring application can also be made by one or more distribution users other than the distribution user Ua.

In step S32, a guest user to be co-starred in the video of the distribution user Ub is selected from the users who have applied for co-starring. The number of guest users selected may be singular or plural. If an upper limit is set for the number of co-stars, guest users are selected until the upper limit is reached.

If the distribution user Ua is selected as the guest user in step S32, the process proceeds to step S33. In step S33, the animation of the character object 131 of the distribution user Ua is generated based on the face motion data of the distribution user Ua. Then, the co-starring video is generated by adding the animation of the character object 131 of the distribution user Ua to the video being distributed (the video including the character object 31 of the distribution user Ub). The process in step S33 is performed, for example, by the co-star application processing unit 61f described above.

Next, the process proceeds to step S34. In step S34, the co-starring moving image generated in step S33 is delivered. This co-starring moving image is distributed to the viewing user device 10 and other viewing user devices and distribution user devices via the network 50. The co-starring moving image includes, for example, an animation of the character object 131 of the distribution user Ua and an animation of the character object 31 of the distribution user Ub, as shown in FIGS. 9 and 10a to 10b.

Next, the process proceeds to step S35. In step S35, it is determined whether or not the co-starring end condition is satisfied. For example, when the character object 131 of the distribution user Ua who is the guest user is in the inactive state, when the guest user evaluation point is equal to or less than a predetermined threshold value, or when the distribution user Ub who is the host user accepts the co-starring end instruction. , When a co-star end instruction is received from the distribution user Ua who is a guest user, when a predetermined time or more has passed from the start of distribution of the co-star video, or when other conditions for ending the co-star are satisfied, the co-star It is determined that the end condition is satisfied. If the co-starring end condition is satisfied, the process proceeds to step S36.

In step S36, a process for terminating the distribution of the co-starring moving image is performed. For example, the character object 131 of the distribution user Ua, which is a guest user, is excluded from the co-starring video, so that the co-starring of the distribution user Ua and the distribution user Ub is terminated. Even if the co-starring is over, the video may continue to be distributed. The moving image distributed after the co-starring is completed does not include the character object 131 of the distribution user Ua. The determination of the co-starring end condition and the co-starring end processing are performed by, for example, the co-starring end processing unit 61g.

Subsequently, an example of the action and effect of the above embodiment will be described. According to the above embodiment, in order to select a distribution user Ub to be a host user and one or more invited users to be co-starring partners, and to perform co-starring with the distribution user Ub to the selected invited user. Since the invitation is sent, the host user can actively start the process for co-starring. The invited user is selected based on the log information of the distribution user Ub and the log information of the co-star candidate user. Therefore, the invited user can be selected based on the usage history of the video distribution system 1. As a result, it is possible to invite an appropriate user as a co-star to the co-star from the aspect of the usage history of the video distribution system 1.

According to the above embodiment, the invited user is selected based on the viewing user information of the distribution user Ub and the viewing user information of the co-star candidate user. Therefore, the invited user is selected in consideration of the difference in the viewing user group of each user. Is selected.

According to the above embodiment, a co-starring candidate user having a small degree of duplication of viewing users and at least one of multiple viewing users is selected as an invited user in relation to the distribution user Ub. As a result, it is possible to promote co-starring between users who have different viewing users. For the distribution user Ub, there is an opportunity to reach the viewing user group that could not be reached before the co-starring.

According to the above embodiment, the invited user is selected based on the co-starring number information of the distribution user Ub and the co-starring number information of the co-starring candidate user, so that the invited user considers the difference in the co-starring number of each user. Be selected. In one embodiment, a co-star candidate user having a large difference in the number of co-stars in relation to the distribution user Ub is selected as an invited user. If the number of co-stars of the distribution user Ub is larger than the number of co-stars of the invited user, the invited invited user will be invited by the host user who is proficient in distributing the co-star video. This makes it easier for invited users to apply for co-starring in response to an invitation, even if they are not familiar with using the co-starring function. As a result, the use of the co-starring function in the video distribution system 1 is promoted. When the number of co-stars of the distribution user Ub is less than the number of co-stars of the invited user, the distribution user Ub can send an invitation to the invited user who is proficient in distributing the co-star video. As a result, the use of the co-starring function in the video distribution system 1 is promoted.

According to the above embodiment, an appropriate invited user can be selected as the co-starring partner in consideration of the commonality or difference between the profiles of the distribution user Ub and the co-starring candidate user. For example, a co-starring candidate user who has many profile items in common with the distribution user Ub can be selected as an invited user.

According to the above embodiment, an appropriate invited user can be selected as the co-starring partner in consideration of the commonality or difference of the social information between the distribution user Ub and the co-starring candidate user. For example, a co-starring candidate user who has many friends in common with the distribution user Ub can be selected as an invited user.

In the video distribution system 1 according to the above embodiment, the distribution users Ua and Ub can distribute a video including a character object that moves according to their facial expressions by the distribution user device 20 provided with a camera such as a smartphone. .. As described above, in the video distribution system 1, since the equipment for the distribution users Ua and Ub to distribute the video is simplified, a platform in which the distribution users Ua and Ub can easily participate is realized.

In the processing procedure described in the present specification, particularly the processing procedure described using the flow chart, a part of the steps (steps) constituting the processing procedure is omitted, as a step constituting the processing procedure. It is possible to add steps that are not specified and / or to change the order of the steps, and the processing procedure in which such omissions, additions, and changes in order are made does not deviate from the gist of the present invention. It is included in the scope of the invention.

At least a part of the functions realized by the computer processor 61 may be realized by a computer processor other than the computer processor 61 of the moving image distribution system 1. At least a part of the functions realized by the computer processor 61 may be realized by, for example, the computer processor 21 of the distribution user device 20 or the computer processor of the viewing user device 10. Specifically, a part or all of the functions of the animation generation unit 61a and the moving image generation unit 61b may be executed by the distribution user device 20. For example, the moving image generated by the distribution user device 20 may be transmitted to the server device 60 and distributed from the server device 60 to the viewing user device 10.

When the distribution user Ua who is watching the video including the character object 31 of the distribution user Ub applies for co-starring with the distribution user Ub, the animation of the character object 131 of the distribution user Ua who applied for co-starring is a server. It may be generated by any of the device 60, the distribution user device 20a of the distribution user Ua, the distribution user device 20b of the distribution user Ub, or the viewing user device 10. Further, the generation of the co-starring video including the generated character object 131 of the distribution user Ua, the distribution video of the distribution user Ub, and the character object 31 is generated by the server device 60, the distribution user device 20a of the distribution user Ua, and the distribution user Ub. It may be performed by either the user device 20b or the viewing user device 10. The co-starring moving image may be shared and generated by the server device 60, the distribution user device 20a, the distribution user device 20b, the viewing user device 10, and other devices. In one example, when the animation of the character object 131 of the distribution user Ua is generated by the distribution user device 20b of the distribution user Ub, the distribution user device 20a of the distribution user Ua is directed to the distribution user device 20b of the distribution user Ub. Then, the face motion data and the voice data of the distribution user Ua are transmitted. When the gift object is included in the co-starring moving image, data for displaying the gift object may be transmitted from the distribution user device 20a or the server device 60 to the distribution user device 20b. In the distribution user device 20b, the animation of the character object 131 is generated by applying the face motion data and the voice data of the distribution user Ua received from the distribution user device 20a to the model data for the distribution user Ua. The model data for the distribution user Ua may be transmitted from the server device 60 to the distribution user device 20a. In another example, when the animation of the character object 131 of the distribution user Ua is generated by the viewing user device 10, the face motion data of the distribution user Ua is generated from the distribution user device 20a of the distribution user Ua to the viewing user device 10. And the voice data is transmitted, and the face motion data and the voice data of the distribution user Ub are transmitted from the distribution user device 20b of the distribution user Ub to the viewing user device 10. In the viewing user device 10, the animation of the character object 131 is generated by applying the face motion data and the voice data of the distribution user Ua received from the distribution user device 20a to the model data for the distribution user Ua, and the distribution user device 20b generates the animation. The animation of the character object 31 may be generated by applying the received face motion data and voice data of the distribution user Ub to the model data for the distribution user Ub. The model data for the distribution user Ua and the model data for the distribution user Ub may be transmitted from the server device 60 to the viewing user device 10. When the gift object is included in the co-starring moving image, data for displaying the gift object may be transmitted from the distribution user device 20a, the distribution user device 20b, or the server device 60 to the viewing user device 10. As described above, the animation of the character object of the distribution user and / or the co-starring moving image including the animation of the character object can be generated by any device included in the moving image distribution system 1. Animations of character objects may be generated by devices not explicitly shown in FIG. The face motion data and voice data of the distribution user Ua are transmitted from the distribution user device 20a of the distribution user Ua to the device that generates the animation of the character object, and the face motion data of the distribution user Ub is transmitted from the distribution user device 20b of the distribution user Ub. And voice data is transmitted. Body motion may be transmitted in addition to face motion.

The co-starring video may include character objects of three or more distribution users. That is, three or more distribution users may virtually co-star in the moving image using each character object. An upper limit may be set for the number of distribution users who can co-star. When the number of distribution users who can co-star reaches the upper limit, the process of not displaying the co-star application button 36 on the image of the video being viewed by the distribution user (for example, image 40a), or the image of the video being viewed by the distribution user. In, a process (disable process) for disabling the co-star application button 36 may be performed.
