Various embodiments of the present invention will now be described with appropriate reference to the drawings. Identical or similar components are provided with the same reference numerals in several drawings.

A video distribution system according to an embodiment will be described with reference to FIGS. 1 to 5. FIG. First, with reference to FIGS. 1 and 2, an outline of a video distribution system 1 according to an embodiment will be described. FIG. 1 is a block diagram showing a video distribution system 1 according to an embodiment, and FIG. 2 shows users Ua and Ub who distribute videos in the video distribution system 1 and distribution user devices used by the users Ua and Ub. It is a schematic diagram which shows typically 20a, 20b. In the moving image distribution system 1, the distribution user device 20a has a function for distributing a moving image including a character object generated based on the movement of the user Ua. It has a function for distributing moving images including character objects generated based on the movement of Ub. For simplicity of explanation, FIG. 2 shows only two users (users Ua and Ub) and distribution user devices 20a and 20b used by each of them. Alternatively, three or more users may use their respective distribution user devices to distribute moving images including character objects generated based on the movements of the respective users. FIG. 1 shows a broadcast user device 20c of broadcast user Uc in addition to broadcast user devices 20a and 20b. Since the distribution user device 20c has functions equivalent to those of the distribution user devices 20a and 20b, detailed description thereof will be omitted. In this specification, when simply referred to as a "distribution user device" without a reference sign, the "distribution user device" can have functions equivalent to those of the distribution user devices 20a and 20b.

As will be described later in detail, the moving image distribution system 1 can generate co-starring moving images including character objects of two or more distribution users. In other words, in the moving image distribution system 1, two or more users can virtually perform together in the moving image via each character object. In this way, when two or more users virtually co-star in a moving image via each character object, the moving image is called a co-starring moving image. Each user who distributes a moving image in the moving image distribution system 1 can apply for co-starring with another user. For example, user Ua can apply for co-starring with user Ub and/or other users. Conversely, user Ub can also apply for co-starring with user Ua and/or other users. Based on this co-starring application, a co-starring moving image including the character object of the user who applied for co-starring and the character object of the user who applied for co-starring is generated.

When a certain user applies for co-starring with another user and two or more users co-star in a video, the user who applied for co-starring may be called a "guest user". Also, a user who originally distributes a moving image and has received an application for co-starring in the moving image may be called a “host user”. The concepts of host user and guest user are relative. For example, when user Ub applies to perform with user Ua, user Ua becomes the host user and user Ub becomes the guest user. Conversely, when user Ua applies to perform with user Ub, User Ua becomes a guest user and user Ub becomes a host user.

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

The moving image delivery system 1 is assumed to be used by many users. Users of the moving image distribution system 1 include distribution users who distribute moving images and viewing users who view the distributed moving images. Users of the moving image distribution system 1 are divided into distribution users and viewing users depending on how the moving image distribution system 1 is used. can be. For example, a distribution user who distributes videos using the video distribution system 1 can view videos distributed by other distribution users using the video distribution system 1. , is the viewing user when viewing the moving image.

In the moving image distribution system 1, it is assumed that a large number of distribution users distribute moving images. Therefore, for example, it is not easy for distribution users Ua, Ub, and Uc to search for co-starring partners among a large number of distribution users. Therefore, the moving image distribution system 1 according to one embodiment of the present invention has a function of supporting selection of co-starring partners by distribution users Ua, Ub, and Uc (and other distribution users). Specifically, the moving picture distribution system 1 sends a co-starring application (hereinafter referred to as "first co-starring application") that does not specify or specify a co-starring partner from a distribution user who wishes to co-star with another user. and, based on the first co-starring application, select the user who will co-star with the co-starring application user who has submitted the first co-starring application. In this specification, the distribution user selected as the co-starring partner of the co-starring application user based on the first co-starring application may be referred to as the "first co-starring user". A first co-starring user is a distributing user (hereinafter referred to as "first 1 co-starring user"). As described above, in the moving image distribution system 1, the co-starring partner is specified by realizing co-starring between the user who applied for the first co-starring application and other users based on the first co-starring application that does not specify the co-starring partner. Alternatively, co-starring with other users can be realized without specifying. As a result, co-starring among distribution users is promoted.

In response to receiving a co-starring application specifying a co-starring partner from a co-starring application user (hereinafter referred to as "second co-starring application"), the moving image distribution system 1 specifies the co-starring application user and the second co-starring application. co-starring user (hereinafter referred to as "second co-starring user") may be determined, and co-starring between the requesting user and the second co-starring user may be realized when it is determined that co-starring is possible. . A second co-starring user is a user who accepts a second co-starring application from another distributing user among a plurality of distributing users who distribute videos using the moving picture distribution system 1 (hereinafter referred to as a "second co-starring user"). ) by the co-star applicant. As a result, the moving image distribution system 1 can realize co-starring between users based on the second co-starring application that designates a co-starring partner. The second co-co-starring user may overlap with the first co-co-starring user. In other words, a certain distribution user may be the first co-starring user and the second co-starring user.

Each of the co-starring application user, the first co-starring user, the second co-starring user, the first co-starring user, and the second co-starring user sends a moving image including a character object generated based on the movement of the user in the moving image distribution system 1. Included in the distribution user who distributes.

Next, an overview of the architecture of the moving image distribution system 1 and the devices constituting the moving image distribution system 1 will be described, and then the function of each device will be described.

The server 60 may be configured to distribute moving images other than moving images containing animation of character objects. The server 60 may provide a social networking service for users to interact with each other, or a platform function for the service, in addition to the video distribution service.

In the moving image distribution system 1, moving images are distributed from the server 60 to the viewing user device 10 and the distribution user devices 20a, 20b, and 20c. The distributed video 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 video using the viewing user device 10 . By viewing the distributed video, distribution users Ua, Ub, and Uc can perform while checking the video being distributed. For simplicity of explanation, only one viewing user device 10 is shown in FIG. 1, but the video distribution system 1 may include a plurality of viewing user devices. Also, although only three distribution user devices are shown in FIG. 1, the video distribution system 1 may include four or more distribution user devices as described above. In addition, as described above, distribution users Ua, Ub, and Uc are also viewing users.

The touch panel may include a capacitive proximity sensor and be configured to detect non-contact operations by the player.

The camera 24 continuously captures images of the faces of the distribution users Ua and Ub, and obtains image data of the faces of the distribution users Ua and Ub. Imaged data of the faces of distribution users Ua and Ub imaged by the camera 24 is transmitted to the server 60 via the communication I/F 22 . The camera 24 may be a 3D camera capable of detecting the depth of a person's face. The camera 24 may acquire imaging data by imaging parts other than the face of the distribution users Ua and Ub, such as hands, legs, fingers, or parts other than these.

The microphone 25 is a sound collecting device configured to convert input sound into sound data. The microphone 25 is configured to be able to acquire the voice input of the distribution users Ua and Ub.

Next, data stored in the storage 63 will be described. In the illustrated embodiment, the storage 63 stores model data 63a, user information 63b, co-starring management information 63c, and various other data necessary for generating and distributing distribution moving images.

The model data 63a is data for drawing a character object associated with each user of the moving image distribution system 1, and is transmitted to the distribution user device in response to a request from the distribution user device. The model data 26a1 and 26b1 stored in the distribution user device 20a are part of the model data 63a, and are data for drawing character objects associated with the distribution users Ua and Ub, respectively. The distribution user devices 20a and 20b can acquire model data 26a1 or model data 26b1 corresponding to their own characters from the server 60. FIG.

An example of user information 63b is shown in FIG. As illustrated, as the user information 63b, various data related to the user are stored in association with the account information of the user who uses the moving picture distribution system 1 . In the example of FIG. 3, a registration flag, a co-starring acceptance flag, and user attribute information are stored in association with the user's account information. The user information 63b may include information other than the above.

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

As described above, in response to receiving a first co-starring application that does not specify a co-starring partner from a co-starring application user, the moving picture distribution system 1 selects a first co-starring user from among the first co-starring users who co-stars with the co-starring application user. is selected to generate a co-starring video in which the co-starring requesting user and the first co-starring user co-star. A registration flag associated with a user's account information indicates whether or not the user is registered as a first co-performing user. For example, if a certain user is not registered as the first co-starring user, the registration flag is set to "0", and if the user is registered as the first co-starring user, the registration flag is set to "1". may be set. A user who wants to increase the chances of co-starring with other users can send a registration request to the server 60 requesting registration as a first co-starring user from his or her distribution user device. Conversely, a user who does not want to co-star with other users based on the first co-starring application may send an exclusion request to the server 60 requesting that he or she be excluded from the first co-starring users. can be done.

As described above, the distribution user who distributes the moving image by the moving image distribution system 1 can perform with the co-starring application user based on the second co-starring application from the co-starring application user. The co-starring request user can make a second co-starring request to the second co-starring user. In the moving image distribution system 1, it is possible to set for each user whether or not to accept a second co-starring request from another user, that is, whether or not the user corresponds to a second co-starring possible user. The user information 63b may include a co-starring acceptance flag indicating whether or not the user is registered as a second co-starring user. A user who does not wish to accept a second co-starring application from another user can set a co-starring acceptance flag so as not to accept a second co-starring application from another user. The co-starring acceptance flag associated with the user's account information indicates whether or not the user is registered as a second co-starring user, that is, whether or not the user accepts a second co-starring application from another user. show. For example, if a user does not wish to accept a second co-starring application from another user, the co-starring acceptance flag is set to "0", and if the user accepts the second co-starring application, "1" may be set as a flag. The user can switch the co-starring acceptance flag by operating the switch button on the setting screen.

The user attribute information associated with the user's account information can include various attribute information of the user. For example, the user attribute information of a certain user may include age, sex, location, hobby, occupation, and various information indicating other attributes of the user. As will be described later, the selection of the first co-starring user from the first co-starring possible users may be performed based on the user attribute information of the co-starring requesting user and the first co-starring possible user. The user information can store various information other than the above in association with the user's account information. The moving image distribution system 1 may provide a function of grouping users. In this case, the user information may store group identification information that identifies the group to which the user belongs in association with the user's account information.

Next, the co-starring management information 63c will be described with reference to FIG. An example of co-star management information 63c is shown in FIG. As illustrated, as co-starring management information 63c, various information for managing the co-starring of the distributing user and other distributing users in association with distributing moving image identification information for identifying the distributing moving images distributed by the distributing user. is stored. The co-starring management information 63c of a certain distributed moving image includes distribution user identification information for identifying a distribution user who is distributing the distributed moving image, co-star number data indicating the number of co-stars co-starring in the distributed moving image, and co-starring users. Co-star user identification information that identifies the may be included.

The distribution moving image identification information of a certain distribution moving image is, for example, a moving image ID that identifies the distribution moving image. The movie ID may be issued to identify the delivered movie when the user starts delivering the movie. The distribution user identification information for a given distribution moving image may be the user ID of the user who is distributing the moving image. The co-starring user identification information for a certain distributed moving image may be the user ID of a co-starring user co-starring with the distributed user in the moving image. When the movie identified by the movie ID is a co-starring movie, the distribution user identification information is the host user's user ID, and the co-starring user identification information is the guest user's user ID.

The co-star number data for a certain distributed moving image indicates the number of co-starring users co-starring with the distributed user in the distributed moving image. In a distributed moving image, an upper limit may be set for the number of co-starring users who can co-star with the distributed user in the distributed moving image. Co-star number data is a natural number equal to or less than the upper limit of the number of co-star users. The upper limit of co-starring users is, for example, five. The upper limit of co-starring users does not have to be five, and can be changed as appropriate. The upper limit of co-starring users may be determined individually for each distribution user. For example, if the maximum number of co-starring users for a given distribution user is five, the maximum number of co-starring users for another distribution user may be three. The upper limit of co-starring users may be uniformly set for all distribution users. Co-star number data is represented by a number equal to or less than the upper limit of co-star users.

FIG. 5 shows an example of a screen displayed on the distribution user device. FIG. 5 shows an example of a screen displayed on the distribution user device 20a. A screen that is the same as or similar to the screen shown in FIG. As illustrated, a menu bar MB is arranged above the screen displayed on the distribution user device 20a. The menu bar MB includes items "recommended", "waiting for co-starring" and "game". The menu bar MB may include items other than these.

In the example shown in FIG. 5, it is assumed that "Recommended" is selected in this menu bar MB. The broadcast user Ua can switch the screen to any of the items included in the menu bar MB by flicking the display 23a of the broadcast user device 20a in the horizontal direction. For example, when the screen corresponding to "recommendation" is displayed, flicking the display 23a to the left can switch to the screen corresponding to the items "game" or "waiting for co-starring".

The screen of FIG. 5 is displayed, for example, after the video application program is started in the distribution user device 20a. When the video application program is activated in the distribution user device 20a, the video being distributed and/or a list of distribution users who are distributing the video are acquired from the server 60. FIG. After starting the application program, a screen corresponding to "Recommended" on the menu bar MB is displayed. The image corresponding to "recommendation" includes, as shown in the drawing, an icon indicating the video being distributed (or an icon indicating the character object of the distribution user who is distributing the video). The “Recommended” screen displays, for example, icons of videos that are highly popular, videos that are attracting attention, or videos that are recommended for viewing for reasons other than these. In the illustrated example, icons 42a to 42d are displayed, each corresponding to a moving image being distributed. Two icons are also hidden behind the setting window 41 .

Indicates that the distribution user of the video has received a second co-starring application from another user (that is, the distribution user is a second co-starring user) in association with the icon of the video being distributed. A message 44a may be displayed. The message 44a includes the text "accepting co-starring". In the example shown in FIG. 5, since the distribution users of the moving images corresponding to the icons 42a, 42c, and 42d have received second co-starring applications from other users, A message 44a is displayed (eg, overlapping each icon). The message 44a is not displayed in association with the icon 42b because the user of the moving image corresponding to the icon 42b has not received a second co-starring application from another user. Further, when the distribution user is the first co-performing user, the co-starring slot information 44b indicating the co-starring slot represented by the difference between the upper limit of the number of co-stars and the number of users co-starring with the distribution user is provided by the distribution user. may be displayed in association with the icon of In the example shown in FIG. 5, it is assumed that the distribution users corresponding to the icons 42a and 42d are the first co-performing users. Co-starring slot information 44b indicating that the co-starring slot is "2" for the distribution user corresponding to the icon 42a is displayed in association with the icon 42a. Co-starring slot information 44b indicating that the co-starring slot is "3" for the distribution user corresponding to the icon 42d is displayed in association with the icon 42d. In this way, in the list of videos being distributed displayed on the distribution user device, it is distinguished whether each distribution user of the videos included in the list is the first co-starring user or the second co-starring user. Is displayed.

A setting button 43 is included in the screen displayed on the distribution user device 20a. When this setting button 43 is selected, a setting window 41 is displayed as shown. This setting window 41 includes switches 41a, 41b, and 41c. Each of the switches 41a, 41b, and 41c is switched on or off according to a user's operation (for example, a left-right sliding operation). The switch 41a is a switch that switches ON/OFF of the registration flag. For example, when the switch 41a is turned on, when the switch 41a is turned on in the distribution user device 20a, the registration flag is switched from the distribution user device 20a to the server 60 to set the distribution user Ua as the first co-performing user. A request to register (hereinafter referred to as a "registration request") is sent. As a result, in the server 60, the registration flag associated with the user ID of the distribution user Ua in the user information 63b is switched from "0" to "1". On the contrary, when the switch 41a is turned off, the registration flag of the user information 63b of the distribution user Ua is switched from "1" to "0".

When the switch 41b is turned on, the distribution user device 20a transmits a request to the server 60 to switch the co-starring acceptance flag and make the distribution user Ua the second co-starring user. As a result, the co-starring acceptance flag associated with the user ID of the distribution user Ua in the user information 63b in the server 60 is switched from "0" to "1". On the contrary, when the switch 41b is turned off, the co-starring acceptance flag of the user information 63b is switched from "1" to "0".

The switch 41c is a switch for transmitting the first co-star application. By turning on the switch 41c, the distribution user device 20a transmits the first co-starring application to the server 60. FIG.

On the screen corresponding to "waiting for co-starring" on the menu bar MB, only the icon of the video for which the distributing user is registered as the first co-starring user among all the videos being distributed included in the list obtained from the server 60 is displayed. may be displayed. In addition, on the screen corresponding to "waiting for co-starring", only the icon of the video for which the distribution user is registered as the second co-performing user among all the videos being distributed included in the list obtained from the server 60 is displayed. may On the screen corresponding to "waiting for co-starring", the distribution user among all videos being distributed included in the list obtained from the server 60 is registered as either the first co-starring user or the second co-starring user. Only the icons of the videos that are present may be displayed. Therefore, by operating the screen to display a screen corresponding to the item "waiting for co-starring", the broadcast user Ua can efficiently search for a co-starring broadcast user.

On the screen corresponding to "Game" in the menu bar MB, a list (not shown) of games provided by the video distribution system 1 in which the distribution user Ua can participate with his/her character object is displayed. The games provided by the video distribution system 1 include party games such as so-called “werewolf games” in which a plurality of players participate. The moving image distribution system 1 can provide a virtual party game in which distribution users participate using character objects. In the real-world party game, real people participate as players, whereas in the virtual party game provided by the moving image distribution system 1, users of the moving image distribution system 1 participate using character objects. The rules of the virtual party game may be the same as the rules of the real world party game. By selecting a desired party game from the screen corresponding to "game", the distribution user Ua can play the selected party game as a game master. At the start of a party game, other participants can be invited to join the game. When broadcast user Ua starts a party game in which his/her own character object participates from a screen corresponding to "game", the broadcast user device 20a instructs the server 60 to set the broadcast user Ua as the first co-performing user. A registration request may be sent. In this case, the distribution user who started the party game is registered as the first co-performing user. Games other than party games may be provided on the screen corresponding to "Game".

The moving picture distribution system 1 may have a function of distributing a play moving picture of a game played by a user while the user is playing the game. This distributed game is, for example, a web game. A list of play videos distributed by the distribution user Ua may be displayed on the screen corresponding to "Game" in the menu bar MB. In the game play video distributed by the distribution user Ub in the video distribution system 1, the character object 31 of the distribution user Ub or the icon of the distribution user Ub may be displayed.

Next, functions realized by the computer processors 21a and 21b will be described more specifically. The computer processor 21a functions as a motion data management unit 21a1, a display control unit 21a2, and a co-starring application unit 21a3 by executing computer-readable instructions included in the moving image application program. Similarly, the computer processor 21b functions as a motion data management unit 21b1, a display control unit 21b2, and a co-starring application unit 21b3 by executing computer-readable instructions included in the distribution program. At least part of the functions implemented by the computer processors 21 a and 21 b may be implemented by computer processors other than the computer processors 21 a and 21 b of the video distribution system 1 . At least part of the functions implemented by the computer processors 21a and 21b may be implemented by the computer processor 61 installed in the server 60, for example.

The motion data management unit 21a1 generates face motion data, which is a digital representation of the movement of the distribution user Ua's face, based on the imaging data of the camera 24a. Similarly, the motion data management unit 21b1 generates face motion data, which is a digital representation of facial movements of the distribution user Ub, based on the imaged data of the camera 24b. Face motion data is generated as needed over time. Face motion data may be generated for each predetermined sampling time interval. In this way, the face motion data generated by the motion data management unit 21a1 can digitally represent the movement of the distribution user Ua's face (change in facial expression) in chronological order. The generated face motion data can digitally represent the facial movements (changes in facial expression) of the distribution user Ub in time series.

In the distribution user device 20, in addition to the face motion data generated by the motion data management unit 21a1, body motion data, which is a digital representation of the position and orientation of each part of the body of the distribution users Ua and Ub other than the face, is generated. may be generated. Distribution user equipment 20 may transmit body motion data to server 60 in addition to face motion data. To generate body motion data, broadcast users Ua and Ub may wear motion sensors. The broadcast user device 20 may be configured to be able to generate body motion data based on detection information from motion sensors attached to broadcast users Ua and Ub. Body motion data may be generated at predetermined sampling time intervals. In this way, the body motion data represents the body motions of distribution users Ua and Ub in time series as digital data. The generation of body motion data based on the detection information of the motion sensors worn by distribution users Ua and Ub may be performed, for example, in a photography studio. A photography 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 sensors worn by broadcast users Ua and Ub may be, for example, Vive Trackers provided by HTC CORPORATION. The base station provided in the photography studio may be, for example, a base station provided by HTC CORPORATION. Also, a supporter computer may be installed in the photography studio and the separate room. A display in the photography studio may be configured to display information received from the support computer. The server 60 may be installed in the same room as the room where the supporter computer is installed. The room in which the supporter computer is installed and the photography studio may be separated by a glass window. In this case, the operator of the supporter computer (also referred to as "supporter" in this specification) can visually recognize the distribution users Ua and Ub. The supporter computer may be configured to be able to change the settings of various devices provided in the photography studio 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 devices other than these.

The face motion data and body motion data generated by the motion data management units 21a1 and 21b1 are collectively referred to as "motion data". The motion data management unit 21a1 outputs the generated motion data to the display control unit 21a2. The display control unit 21a2 controls, in the viewing mode, the motion data generated by the motion data management unit 21a1, the audio data related to the audio acquired from the microphone 25, the model data 26a1, the object data 26a2, and other data as necessary. Rendering is performed based on the data to generate moving image data including animation of the object of the character of the distribution user Ua. The data used to generate the video data including the animation of the object of the character of the distribution user Ua is referred to as "animation configuration data". Ua's animation configuration data". The animation configuration data of broadcast user Ua can include, for example, motion data of broadcast user Ua, model data 26a1 of broadcast user Ua, and object data 26a2. The display control unit 21b2 performs rendering in the same manner as the display control unit 21a2, based on the animation configuration data of the distribution user Ub. The description regarding the display control section 21a2 also applies to the display control section 21b2 as long as there is no contradiction.

Rendering refers to drawing processes including perspective projection, hidden surface removal (rasterization), shading, texture mapping, and other known processes. The display control unit 21a2 outputs the generated moving image data to the display 23a and a speaker (not shown). Animation of the object of the distribution user Ua's character is generated by applying motion data to the model data 26a1. The display control unit 21a2 synthesizes or superimposes the object of the character of the distribution user Ua with other information to generate moving image data, and outputs the generated moving image data to the display 23a. The information synthesized or superimposed with the animation may include messages posted by the viewing user, notifications sent from the server 60, GUI (Graphical User Interface) parts such as operation buttons, and other information. .

When the distribution user Ua co-stars with another user, the display control unit 21a2 receives the animation configuration data necessary for generating the object of the co-star's character from the distribution user device of the co-starring partner's distribution user. Acquired via a server 60 and rendered based on the acquired animation configuration data of the co-starring partner and the acquired animation configuration data of the distribution user Ua, the co-starring moving image including the object of the character of the distribution user Ua and the object of the character of the co-starring partner Generate data. The generated co-starring moving image data is output to the display 23a.

The display control unit 21a2 can transmit part or all of the animation configuration data of the distribution user Ua to the server 60 in order to distribute the animation of the distribution user Ua.

The co-starring application unit 21a3 transmits to the server 60 a co-starring application requesting co-starring with another broadcast user based on the operation of the broadcast user Ua on the broadcast user device 20a. Similarly, the co-starring application unit 21b2 transmits to the server 60 a co-starring application requesting co-starring with another broadcast user based on the operation of the broadcast user Ub on the broadcast user device 20b. The explanation regarding the co-starring application section 21a3 also applies to the co-starring application section 21b3 as long as there is no contradiction. The co-starring application transmitted from the distribution user devices 20a and 20b may be a first co-starring application that does not specify a co-starring partner, or a second co-starring application that specifies a co-starring partner.

The first co-starring application is to co-star with one of the first co-starring users who set the registration flag to ON among the distribution users who are distributing the video in the video distribution system 1 without specifying the co-starring partner. It's a request to make a request. The first co-star application may include the user ID of the user who sends the first co-star application. Information for designating, identifying, or identifying a co-starring partner may not be included in the first co-starring application. For example, when the distribution user Ua transmits a first co-starring application from the distribution user device 20a, the first co-starring application includes a user ID that identifies the distributing user Ua, but does not include information specifying a co-starring partner. No.

For example, in the setting screen window 41 shown in FIG. 5, the first co-starring application is sent from the distribution user device 20a to the server 60 in response to the user's operation (for example, rightward sliding operation) on the switch 41c. may be sent to The first co-starring application may be sent to the server 60 by a method other than the operation of the switch 41c. For example, the first co-starring application is sent from the distribution user device 20a to the server 60 in response to an operation button displayed on the home screen, an operation button displayed superimposed on the video being distributed, or an operation button other than these. may be sent to In this way, the first co-starring application can be transmitted from the distribution user device to the server 60 while the distribution user is watching the distributed video and/or while the distribution user is not watching the video. The first co-starring application may be transmitted to the server 60 not only from the distribution user device 20a, but also from the distribution user device 20b and other distribution user devices.

The second co-starring application is a request for co-starring with a specific co-starring partner. Therefore, the second co-starring application includes a user ID for identifying the co-starring partner. The second co-starring application differs from the first co-starring application, which does not include identification information for identifying the co-starring partner, in that the second co-starring application includes identification information for identifying the co-starring partner. As will be described later, the second co-starring application may be transmitted from the distribution user device 20a to the server 60 in response to the selection of the co-starring application button 36 displayed while watching the distributed video. .

Next, functions realized by the computer processor 61 will be described more specifically. The computer processor 61 functions as a distribution management section 61a, a user registration section 61b, a first co-starring application processing section 61c, and a second co-starring application processing section 61d by executing computer-readable instructions included in the distribution program. .

The distribution management unit 61a stores various data received from the viewing user device 10 or the distribution user device 20 in the storage 63 or other storage. The distribution management unit 61a obtains data requested by the viewing user device 10 or the distribution user device 20 from the storage 63 or other storage, and sends the obtained data to the requesting viewing user device 10 or the distribution user device 20. Send. For example, in response to a request from the viewing user device 10 or the distribution user device 20, the distribution management unit 61a transmits a list of videos being distributed to the requesting viewing user device 10 or the distribution user device 20. FIG. When the distribution management unit 61a receives from the viewing user device 10 or the distribution user device 20 a viewing request for the moving image including the identification information of the moving image selected from the list, the distribution management unit 61a generates animation configuration data related to the moving image specified by the identification information. is transmitted to the requesting viewing user device 10 or the broadcasting user device 20 . Upon receiving the animation configuration data, the viewing user device 10 or the distribution user device 20 performs rendering based on the received animation configuration data, thereby generating video data of the video requested to be viewed, and displaying the video data on a display or the like. Can be output to speakers. In this way, the distribution management unit 61a distributes the requested moving image by transmitting the animation configuration data of the requested moving image to the viewing user device 10 and the distributing user device 20 .

When the distribution management unit 61a receives a posted message from the viewing user device 10 or the distribution user device 20 for a moving image being distributed, the distribution management unit 61a sends the received posted message to the distribution user device and It is transmitted to the viewing user device 10 and the distribution user device 20 that are viewing the moving image. The posted message may include text data indicating the content of the message, the user ID of the user who posted the posted message, the date and time of posting, and other information. The viewing user device 10 or the distribution user device 20 that has received the posted message can display the message and the poster of the received posted message.

The distribution management unit 61 a can transmit system notifications related to distribution or viewing of moving images to the viewing user device 10 or the distribution user device 20 . For example, when user A starts viewing a moving image, the distribution management unit 61a sends a notification message "User A has entered the room" to the distribution user device of the distribution user of the moving image and the distribution that is distributing the moving image. It can be transmitted to the user's broadcasting user device and the viewing user device 10 and broadcasting user device 20 watching the moving image. The viewing user device 10 or the broadcasting user device 20 that has received the notification message can display the received notification message.

When the host user and the guest user are co-starring, the distribution management unit 61a transmits the host user's animation configuration data to the guest user's distribution user device 20, and transmits the guest user's animation configuration data to the host user's distribution user device. 20. Each of the distribution user devices 20 of the guest user and the host user performs rendering based on the animation configuration data of the co-starring partner received from the distribution management unit 61a, and generates moving image data including animation of the object of the co-starring partner's character. As a result, the distribution user device 20 of each of the co-starring host user and guest user can generate moving image data including the object animation of its own character and the object animation of the co-starring partner's character. In addition, when the server 60 receives a viewing request requesting viewing of a co-starring video in which the host user and the guest user co-star from the viewing user device 10 or the distribution user device, the distribution management unit 61a sends the viewing request to the source of the viewing request. The host user's animation configuration data and the guest user's animation configuration data are transmitted to a certain viewing user device 10 or broadcasting user device. The viewing user device 10 or the distribution user device that has received the animation configuration data of the host user and the animation configuration data of the guest user performs rendering based on the animation configuration data of the host user and the animation configuration data of the guest user, thereby rendering the animation configuration data of the host user. and the character object of the guest user. As a result, the user who requested to view the co-starring moving image can view the co-starring moving image on the viewing user device 10 or the distribution user device.

In one or a plurality of embodiments of the present invention, when the user registration unit 61b receives a registration request requesting registration as a first co-starring user from the distribution user device of any user, the user is registered as the first user. Register as a user who can co-star. The registration request may be sent to server 60 by operating switch 41a on the distribution user equipment, as described above. A registration request transmitted from a distribution user may include a user ID that identifies the distribution user. Upon receiving a registration request from a certain user's distribution user device, the user registration unit 61b sets the registration flag associated with the user ID included in the registration request in the user information 63b to "1". be able to. By setting the registration flag corresponding to the user ID to "1", the user identified by the user ID becomes the first co-permitted user.

In one or a plurality of embodiments of the present invention, when the first co-starring application processing unit 61c receives a first co-starring application from the distribution user device of any user (co-starring application user) of the video distribution system 1, A first co-starring user is selected from one co-starring user. In response to the selection of the first co-starring user based on the first co-starring application from the co-starring requesting user, distribution of the co-starring video between the co-starring requesting user and the first co-starring user is started. Specifically, in the co-starring management information 63c, the user ID of the co-starring requesting user is stored in association with the video ID of the video distributed by the first co-starring user. Accordingly, by referring to the co-starring management information 63c, it can be determined that the co-starring requesting user and the first co-starring user are co-starring. When the server device 60 receives a viewing request including the video ID of the co-starring video co-starred by the co-starring application user and the first co-starring user, the distribution management unit 61a associates the video ID included in the viewing request with the viewing request. Acquires the user ID of the host user and the user ID of the guest user who are co-starring, acquires the animation configuration data of the host user who is co-starring and the animation configuration data of the guest user based on these user IDs, and acquires the acquired animation of the host user The configuration data and the guest user's animation configuration data are transmitted to the viewing user device 10 or the broadcasting user device that is the source of the viewing request. The distribution management unit 61a can thus distribute the co-starring moving image to the viewing user device 10 or the distribution user device.

When receiving the first co-starring application, the first co-starring application processing unit 61c, for example, refers to the user information 63b to identify the user whose registration flag is set to "1" as the first co-starring user. A first co-starring user to be a co-starring partner of the co-starring application user who sent the first co-starring application can be selected from among the first co-starring users thus specified. The first co-starring application processing unit 61c can select a first co-starring user from among the first co-starring users according to various algorithms. In one embodiment, the first co-starring application processing unit 61c can randomly select one first co-starring user from among the first co-starring possible users. In another embodiment, the first co-starring application processing unit 61c refers to the co-starring management information 63c to identify the number of co-stars in the video distributed by each of the first co-starring users, and A first co-starring user is selected based on the number of co-stars. For example, the first co-starring application processing unit 61c may select, as the first co-starring user, the user with the smallest number of co-starring users among the first co-starring users. The first co-starring application processing unit 61c selects the first co-starring user with the smallest number of co-stars (for example, the first co-starring user whose number of co-stars is set to "0" without co-starring with anyone). exists, the first co-star user may be randomly selected from among the first co-co-star users with the smallest number of co-stars. When the user ID of the first co-starring user is not recorded as the distribution user identification information of the co-starring management information 63c, the first co-starring user does not distribute the moving image, so in selecting the first co-starring user , the number of co-stars of the first co-co-star-possible user can be set to "0".

In one embodiment of the present invention, the first co-starring application processing unit 61c determines the co-starring frame, which is the difference between the upper limit of the number of co-stars and the number of co-stars actually co-starring for each of the first co-starring users. A first co-user can be selected based on. For example, for a first co-starring user, if the upper limit of the number of co-stars is "5" and the number of co-starring users is "1" (that is, co-starring with only one user), , the first co-starring user's co-starring slot is "4". In one embodiment of the present invention, the difference between the upper limit of the number of co-stars for each of the first co-starring users and the number of co-stars who are actually co-starring is calculated as a co-starring frame. A user with the largest co-starring frame may be selected as the first co-starring user. In this way, by selecting the user with the smallest number of co-stars or the user with the largest co-starring frame among the first co-starring users as the first co-starring user, co-starring with other users among the first co-starring users is possible. A user who is relatively inactive is more likely to be selected as the first co-starring user.

In another embodiment of the present invention, the user with the smallest co-starring slot (however, the co-starring slot is not "0") among the first co-performing users may be selected as the first co-starring user. As a result, a user who has already co-starred with another user is more likely to be selected as the first co-starring user, so that the co-starring requesting user can co-star with a distribution user who is already actively co-starring with another distribution user. can.

In one embodiment of the present invention, the first co-starring application processing unit 61c selects the first co-starring user from among the first co-starring possible users based on the user attribute information of each of the co-starring requesting user and the first co-starring possible user. . As described above, the user information 63b may include user attribute information indicating various attributes of each user. For example, the first co-starring application processing unit 61c identifies the user attribute information of the co-starring application user based on the user ID of the co-starring application user included in the first co-starring application, and specifies the user attribute information of the co-starring application user and the first co-starring application. A score representing the degree of matching with each possible user's user attribute information is calculated based on a predetermined algorithm, and the user with the highest score among the first co-co-starring users is selected as the first co-co-starring user. good too. When calculating the score representing the degree of matching, individual attribute data (for example, place of residence, age, sex, hobby) included in the user attribute information may be weighted. As a result, for example, among the first co-starring users, users who live close to the co-starring requesting user, users whose age group overlaps with the co-starring requesting user, and users who have common hobbies with the co-starring requesting user are selected as the first co-starring users. easier to be selected. In this way, a user whose attribute data included in the user attribute information has a high matching degree can be selected as the first co-starring user from among the first co-starring users. Therefore, even if a co-starring video is generated based on a first co-starring application that does not specify a co-starring partner, it becomes easy for co-starring users to find common topics. As a result, it is possible to promote communication in the co-starring video started based on the first co-starring application.

In one embodiment of the present invention, when a second co-starring application from a co-starring requesting user is received, the second co-starring application processing unit 61d determines whether or not to permit the second co-starring request of the co-starring requesting user. . As described above, the second co-starring application is transmitted to the server 60 by, for example, selecting the co-starring application button 36 while viewing the distributed video, and the transmitted second co-starring application is accepted by the server 60. may For example, when receiving a second co-starring application requesting co-starring with the distributing user Ub from the distributing user Ua, the second co-starring application processing unit 61d determines whether the distributing users Ua and Ub can co-star. The second co-starring application processing unit 61d, for example, transmits a message inquiring whether or not to permit the co-starring application from the broadcast user Ua to the broadcast user device 20b of the broadcast user Ub. You may decide whether to co-star.

Next, display of images corresponding to moving images distributed in the moving image distribution system 1 will be described with reference to FIGS. 6 to 8. FIG. In these figures, the viewing user of the viewing user device 10 and the distribution user Ua of the distribution user device 20a select the viewing of the moving picture being distributed by the distribution user Ub from the list of moving pictures being distributed, and request to view the moving picture. is transmitted to the server 60, and in response to this viewing request, the server 60 transmits the animation configuration data of the distribution user Ub to the viewing user device 10 and the distribution user device 20a. , is rendered based on the animation composition data of broadcast user Ub received from server 60 . The animation configuration data of the distribution user Ub may include motion data generated by the motion data management unit 21b1 in the distribution user device 20b of the distribution user Ub and sound data generated based on the sound detected by the microphone 25b. Also, it is assumed that the distribution user device 20b performs rendering based on the animation configuration data of the distribution user Ub acquired from the server 60 or the animation configuration data generated by the device itself. 6 shows an example of a video image displayed on the viewing user device 10, FIG. 7 shows an example of a video image displayed on the distribution user device 20a, and FIG. 8 shows an example of a video image displayed on the distribution user device 20b. 4 shows an example of an image of a moving image to be displayed.

On the display of the viewing user device 10, as shown in FIG. 6, an image corresponding to the moving image data generated by performing rendering based on the animation configuration data of the distribution user Ub received from the server 60 is displayed. It is The image displayed on the viewing user device 10 includes a character object 31 of the distribution user Ub generated by rendering, a gift button 32, an evaluation button 33, a comment button 34, a comment display area 35, It is included.

On the display 23a of the distribution user device 20a, as shown in FIG. 7, an image 30 corresponding to the moving image data generated by rendering based on the animation composition data of the distribution user Ub received from the server 60 is displayed. is displayed. This image 30 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, similar to the moving image displayed on the viewing user device 10. and are included. In addition to this, the image 30 includes a co-star application button 36 for applying for co-starring with the broadcast user Ub in the moving image distributed by the broadcast user Ub. When the co-starring application button 36 is operated, a second co-starring application is transmitted to the server 60 . The distribution user device 20a can display the distributed moving image image 30 by executing application software including, for example, a moving image application program. In one embodiment of the present invention, the co-starring application button 36 for sending the second co-starring application for applying for co-starring with the broadcast user Ub is displayed on the broadcast user device only when the video of the broadcast user Ub is being viewed. may be In one embodiment of the present invention, the co-starring application button 36 is displayed on the image 30 on the broadcast user device 20a only when the broadcast user Ub is registered as a second co-starring user, and the broadcast user Ub is registered as the second co-starring user. If the user is not registered, it may not be displayed on the distribution user device 20a.

As shown in FIG. 6 , the image of the moving image displayed on the viewing user device 10 does not include the co-starring application button 36 . For example, if the application software including the distribution program is not downloaded or installed in the viewing user device 10, or if the application software including the distribution program is not activated in the viewing user device 10, the viewing user device 10 Co-starring application button 36 is not displayed. When application software including a video application program is downloaded or installed in the viewing user device 10, or when application software including the video application program is activated in the viewing user device 10, the viewing user device 10 also has Co-starring application button 36 may be displayed.

Since the character object 31 is generated by applying the motion data of the distribution user Ub to the model data 63b, the facial expression and movement of the character object 31 change in synchronization with the movement of the facial expression of the distribution user Ub.

The gift button 32 is displayed on the display screen 30 so as to be selectable by operating the viewing user device 10 . The gift button 32 can be selected, for example, by tapping an 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 display screen 30 displays a message for selecting a gift to be gifted to the distribution user (distribution user Ub in this case) who is distributing the video being viewed. window is displayed. The viewing user can purchase a gift to be gifted from among the gifts displayed in the window. In another embodiment, a window containing a list of purchased gifts is displayed on display screen 30 in response to selection of gift button 32 . In this case, the viewing user can select a gift to be gifted from the gifts displayed in the window. Gifting information may be sent to server 60 when gift button 32 is selected on viewing user device 10 . This gifting information may include gift identification information (gift ID) that identifies the gift to be gifted. In this way, the viewing user viewing the moving image can select the gift button 32 to provide (gifting) a desired gift to the distribution user distributing the moving image.

The evaluation button 33 is displayed on the display screen 30 so as to be selectable by the viewing user using the viewing user device 10 . The evaluation button 33 can be selected, for example, by tapping an area of the touch panel of the viewing user device 10 where the evaluation button 33 is displayed. When an evaluation button 33 is selected by a viewing user who is viewing a video, a positive evaluation is given to the distribution user (distribution user Ub in the illustrated example) who distributes the video, or an affirmative evaluation is given to the video being distributed. Evaluation information may be transmitted to the server 60 indicating that a positive evaluation has been made.

A comment button 34 is displayed on the display screen 30 so as to be selectable by the user. When the comment button 34 is selected by tapping, for example, a comment input window for inputting a comment is displayed on the display screen 30 . The viewing user can input comments via the input mechanism of the viewing user device 10 or the broadcasting user device 20a. The input comments are transmitted to the server 60 from the viewing user device 10 and the distribution user device 20a. The server 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 moving image. In the comment display area 35, comments posted by each user are displayed, for example, in chronological order. The comment display area 35 occupies part of the display screen 30 . The number of comments that can be displayed in the comment display area 35 has an upper limit. In the illustrated example, up to three comments can be displayed in the comment display area 35 . When comments exceeding the upper limit set in the comment display area 35 are posted, the comments are deleted from the comment display area 35 in order of posting time. Therefore, the display time of each comment in the comment area 35 becomes shorter as the frequency of received comments becomes higher. When a comment exceeding the upper limit set in the comment display area 35 is posted, a comment with a new posting time is displayed in the comment display area 35, and an old post that cannot be displayed in the comment display area 35 is displayed. The comment may be displayed within the comment display area 35 in response to the comment display area 35 being swiped.

As shown in FIG. 8, the display 23b of the distribution user device 20b displays an image 40 corresponding to the moving image data generated by rendering based on the animation configuration data of the distribution user Ub. . This image 40 includes a character object 31 corresponding to distribution user Ub and a comment display area 35 . The image 40 displayed on the distribution user device 20b includes the same background image as the moving image and the image 30, the character object image, and the comment. On the other hand, the image 40 differs from the image 30 in that the gift button 32, the evaluation button 33, the comment button 34, and the co-starring application button 36 are not included.

Next, with reference to FIGS. 9 to 12, display of images corresponding to co-starring moving images distributed in the moving image distribution system 1 will be described. 9 shows an example of an image of a co-starring moving image displayed on the viewing user device 10, FIG. 10 shows an example of an image of a co-starring moving image displayed on the distribution user device 20c of the distribution user Uc, and FIG. shows an example of an image of a co-starring moving image displayed on the distribution user device 20a, and FIG. 12 shows an example of an image of a co-starring moving image displayed on the distribution user device 20b. In these figures, broadcast user Ub is selected as the first co-starring user based on the first co-starring application from broadcast user device 20c used by broadcast user Uc, and character object 131 of broadcast user Uc and character object of broadcast user Ub are selected. It is assumed that co-star videos including 31 are being distributed. That is, in the illustrated embodiment, the distribution user Uc is a co-starring application user and a guest user. Also, the distribution user Ub is the host user. In addition, it is assumed that a viewing request requesting viewing of the co-starring moving image is transmitted from the viewing user device 10 and the distributing user device 20a, and the co-starring moving image is distributed to the viewing user device 10 and the distributing user device 20a. ing.

The displays of the viewing user equipment 10, the broadcasting user equipment 20c, the broadcasting user equipment 20a, and the broadcasting user equipment 20b display the messages received from the server 60, as shown in FIGS. 9, 10, 11, and 12, respectively. An image corresponding to the moving image data generated by performing rendering based on the animation configuration data of the broadcast user Uc and the broadcast user Ub is displayed. The image of the co-starring moving image displayed on the viewing user device 10 includes the character object 131 of the distribution user Uc in addition to the character object 31 of the distribution user Ub. The co-starring application user's character object 131 is generated based on the motion data included in the distribution user Uc's animation configuration data. The image displayed on the viewing user device 10 includes a gift button 32, an evaluation button 33, a comment button 34, and a comment display area 35, similar to the image of the moving image before co-starring starts shown in FIG. , contains Since broadcast user Uc has already performed with broadcast user Ub, the co-starring application button 36 is not displayed on the broadcast user device 20c of broadcast user Uc. Similar to the image displayed on the distribution user device 20b shown in FIG. 12, the image displayed on the distribution user device 20c shown in FIG. 10 includes a gift button 32, an evaluation button 33, and Comment button 34 is not included, but comment display area 35 is included.

The image of the co-starring moving image displayed on the distribution user device 20a includes a gift button 32, an evaluation button 33, a comment button 34, and a comment display area in the same way as the image before co-starring starts shown in FIG. 35 and a co-star application button 36. The distribution user Ua can select the co-starring application button 36 even when the co-starring moving image is being reproduced. When the co-starring application button 36 is selected during the reproduction of the co-starring moving image in which the distributing user Ub is the host user, the second co-starring application requesting co-starring with the distributing user Ub is transmitted from the distributing user device 20 a to the server 60 . be. When the server 60 accepts the second co-starring application from the distribution user device 20a, the second co-starring application processing unit 61d determines whether or not to permit the co-starring of the distribution user Ua with the distribution user Ub based on the second co-starring application. determine whether When distribution user Ua's co-starring with distribution user Ub is permitted, distribution user Ua's character object is also displayed in the co-starring video in which distribution user Uc and distribution user Ub co-star. In this case, the character object (not shown) of broadcast user Ua is displayed in addition to the character object 31 of broadcast user Ub and the character object 131 of broadcast user Uc in the co-starring moving images shown in FIGS.

The image of the co-starring moving image displayed on the distribution user device 20b includes a comment display area 35, like the image before co-starring starts shown in FIG. In addition, a co-starring end button 45 for ending the co-starring is displayed in the image of the co-starring moving image. The co-starring end button 45 is displayed on the broadcast user device 20b of the broadcast user Ub who is the host user who has received the co-starring application, but is displayed on the broadcast user device 20a of the broadcast user Ua who is not co-starring and the broadcast user who is the guest user. It is not displayed on the distribution user device 20c of Uc. When the co-starring end button 45 is selected on the broadcast user device 20b of the broadcast user Ub, a process for terminating the co-starring between the broadcast users Uc and Ub is performed. For example, a co-starring end instruction is transmitted to the server 60 from the distribution user device 20b in response to the co-starring end button 45 being selected. When the server 60 receives the co-starring end instruction, the distribution management unit 61a ends the transmission of the animation configuration data of the distribution user Uc. As a result, the character object 131 of the distribution user Uc is no longer displayed in the image of the distribution moving image.

The image of the co-starring moving image is a horizontally long image as illustrated. The co-starring moving image generation unit 61g or the moving image distribution unit 61c distributes the co-starring moving image as a horizontally long moving image. As a result, the distributed image of the co-starring moving image is displayed on the viewing user device 10 as a horizontally long image. In one embodiment, even if the original video (image) is portrait as shown in FIG. 6, the co-star video is converted to landscape and delivered. Since the co-starring moving image includes the character objects of the two delivery users, it is easier to display the character objects for the two characters without duplication by using a horizontally long image. For example, in a co-starring video, the left half may be assigned to the original distribution user's character object, and the right half may be assigned to the co-starring requesting user's character object. The allocation of areas to each distribution user may be determined arbitrarily so that character objects do not overlap each other. Although the image of the co-starring moving image is shown as a horizontally long image in the illustrated embodiment, the co-starring moving image may be a vertically long image.

Next, with reference to FIG. 13, co-starring video distribution processing in one embodiment will be described. FIG. 13 is a flow diagram showing the flow of processing for distributing a co-starring video in one embodiment. In the co-starring moving image distribution process described with reference to FIG. 13, it is assumed that the distributing user Ub is selected as the first co-starring user based on the first co-starring application from the distributing user Uc.

At the start of the co-starring moving image distribution process in FIG. 13, many distribution users including the distribution user Ub are distributing moving images including their own character objects. In step S<b>11 , it is determined whether or not a first co-starring application has been made by any of the distribution users of the moving image distribution system 1 . The first co-starring application is made, for example, by distribution user Uc. If the delivery user Uc makes the first co-star application, the process proceeds to step S12.

In step S12, a first co-starring user is selected from first co-starring users based on a first co-starring application from distribution user Uc. In the illustrated embodiment, broadcast user Ub is selected as the first co-starring user. As a result, co-starring between broadcast user Ub (host user) and broadcast user Uc (guest user) is started. In step S12, distribution user Ub is selected as the first co-starring user. The selection of the first co-starring user is performed by, for example, the first co-starring application processing unit 61c.

In step S12, distribution user Ub was selected as the first co-starring user based on the first co-starring application from distributing user Uc. be delivered. Specifically, in addition to the animation configuration data of the distribution user Ub, the animation configuration data of the distribution user Uc is transmitted to the viewing user device 10 and the distribution user device that are viewing the video of the distribution user Ub. The viewing user device 10 and the distribution user device that have received these animation configuration data perform rendering based on the received animation configuration data, for example, as shown in FIGS. An image of a moving image including the character object of distribution user Uc can be displayed.

Next, with reference to FIG. 14, processing for distributing a co-starring moving image based on the second co-starring application will be described. FIG. 14 is a flow diagram showing the flow of processing for distributing a co-starring video in one embodiment. In the process of distributing a co-starring moving image described with reference to FIG. 14, it is assumed that a co-starring application is made to the distributing user Ub from the distributing user Ua who is viewing the moving image including the character object of the distributing user Ub. ing. The process of distributing the co-starring moving image shown in FIG. 14 may be performed in parallel with the process of distributing the moving image shown in FIG. 13 .

First, in step S21, it is determined whether or not a second co-starring application has been made by a user other than the distribution user Ub during the distribution of the moving image including the character object of the distribution user Ub. The second co-starring application is made by, for example, the distribution user Ua. If the distribution user Ua has applied for the second co-starring, the process proceeds to step S22.

In step S22, it is determined whether or not the second co-starring application from the distribution user Ua is permitted. For example, when the distribution user Ub is notified that the distribution user Ua has applied for co-starring, and the distribution user Ub replies to the notification that the distribution user Ub permits co-starring with the distribution user Ua, Co-starring with broadcast user Ub is permitted. For example, the second co-starring application processing unit 61d determines whether or not to permit the co-starring application.

If it is determined in step S22 that the application for co-starring is permitted, co-starring between broadcast user Ub (host user) and broadcast user Ua (guest user) is started, and the process proceeds to step S23. A co-starring video in which the user Ub and the distribution user Ua co-star is distributed. Specifically, in addition to the animation configuration data of the distribution user Ub, the animation configuration data of the distribution user Ua is transmitted to the viewing user device 10 and the distribution user device that are viewing the video of the distribution user Ub. The viewing user device 10 and the distribution user device that have received these animation configuration data perform rendering based on the received animation configuration data, thereby displaying moving image images including the character objects of the distribution user Ub and the distribution user Ua. be able to.

The operation and effect achieved by the above embodiment will be described. In one or more of the above embodiments, a user who wishes to co-star with another distribution user makes a first co-star application without specifying a co-star, and selects based on this first co-star application. You can co-star with the selected first co-star user. In this way, it is possible to apply for co-starring without specifying a co-starring partner.

In one or a plurality of embodiments of the present invention, a distribution user who distributes moving images can receive a first co-starring application by registering as a first co-starring user. Therefore, it is possible to provide the distribution user with means for increasing the chances of co-starring with other users. On the other hand, if the distribution user does not register as the first co-starring user, the first co-starring application can prevent the co-starring application user from unexpectedly participating in his or her moving image.

In one or a plurality of embodiments of the present invention, it is possible to co-star with the first co-starring user simply by applying for the first co-starring without obtaining permission from the co-starring partner. Therefore, it is possible to co-star with other distribution users in a simpler process than the conventional co-starring start process in which co-starring can be started only when the co-starring application is permitted. Since the first co-starring user is selected from among the first co-starring users, co-starring with the co-starring application user is permitted when the first co-starring application is accepted by registering as the first co-starring user. can be considered to exist.

In one or a plurality of embodiments of the present invention, the first co-starring application can be made even when the video of the distribution user who is the co-starring partner is not viewed. For example, by opening the setting window 41 while viewing a list of videos being distributed and operating the switch 41c included in this setting window, the first co-star application can be made. In this way, co-starring is possible even if the user is not watching the video of the broadcast user who is the co-starring partner. can be reduced, which encourages users to co-star in videos.

In one or a plurality of embodiments of the present invention, by setting an upper limit on the number of users that a distribution user can co-star with, it is possible to prevent adverse effects caused by an excessive number of users co-starring in one video. For example, it is possible to prevent the load of processing for joining and leaving a co-starring video and processing for generating a co-starring video from becoming excessive.

In one or a plurality of embodiments of the present invention, a user with the smallest number of co-starring users among the first co-starring users can be selected as the first co-starring user based on the first co-starring application. As a result, a distribution user with few or no co-starring users is more likely to be selected as the first co-starring user. can be provided preferentially. In addition, in one or more embodiments of the present invention, a distribution user with a large number of co-starring users (co-starring slot) represented by the difference between the upper limit of the number of users who can co-star and the number of users who are actually co-starring can be selected as the first co-user. This makes it possible to preferentially provide opportunities for co-starring with other users to distribution users who have many co-star slots.

In one or a plurality of embodiments of the present invention, based on an algorithm that makes it easier for distribution users with a small number of co-starring users (co-starring slots) to be selected as first co-starring users, first co-starring users among first co-starring users are selected. User may be selected. As a result, a distribution user who has already co-starred with other distribution users is likely to be selected as the first co-starring user. can be made

In one or more embodiments of the present invention, the first co-starring user is selected from among the first co-starring users based on the user attribute information of the co-starring requesting user and the user attribute information of the first co-starring user. can. As a result, for example, a user whose user attribute information has a high degree of matching with the co-starring requesting user can be selected as the first co-starring user from among the first co-starring users. Therefore, even if a co-starring video is generated based on a first co-starring application that does not specify a co-starring partner, it becomes easy for co-starring users to find common topics.

In one or more embodiments of the present invention, a co-starring applicant makes a second co-starring application that specifies a co-starring partner, and if co-starring is permitted based on this second co-starring application, the second co-starring application You can co-star with the specified co-star. Since it is assumed that a distribution user who does not want to co-star with an unauthorized co-star is not registered as a first co-star possible user, only the co-star function based on the first co-star application in which the video distribution system 1 does not specify the co-star is specified. is provided, it is not possible to provide an opportunity for co-starring to distribution users who do not want to co-star with unauthorized co-stars. By providing a function of co-starring with a partner who is permitted to co-star, even a distribution user who does not want to co-star with a non-permitted co-star can be provided with an opportunity to co-star with other users.

In one or more embodiments of the present invention, the second co-starring application is made to the distribution user who is distributing the video being viewed, so only co-starring application users who are interested in the video being distributed A second co-starring application can be accepted.

In one or a plurality of embodiments of the present invention, a list of distribution users who are currently distributing moving images is displayed, and the first co-starring user is displayed in the list so as to be distinguishable from other distribution users. For example, in the list of videos or video distribution users displayed as "recommended", the icon corresponding to the first co-starring user (or the video distributed by the first co-starring user) is associated with the "co-starring frame 2”, etc., is displayed to indicate that co-starring is possible based on the first co-starring application. This allows the co-starring requesting user to confirm potential co-starring distribution users before making the first co-starring request.

In one or more embodiments of the present invention, a user who has started a game in which a plurality of distribution users participate (for example, a party game in which character objects participate) can be registered as a first co-performing user. . This makes it easier for the user who started the game to be selected as the first co-starring user based on the first co-starring application. Since the user who started the game has a common topic of the game, even if the users who have no prior knowledge about each other play together based on the first co-starring application, they can smoothly collaborate.

In the processing procedures described in this specification, especially in the processing procedures described using flow diagrams, some of the steps that make up the processing procedure are omitted, and as a step that makes up the processing procedure It is possible to add unspecified steps and/or change the order of the steps, and the processing procedures in which such omissions, additions, and order changes do not deviate from the spirit of the present invention. Included within the scope of the invention.

At least part of the functions implemented by the computer processor 61 may be implemented by a computer processor other than the computer processor 61 of the video distribution system 1 . At least part of the functions implemented by the computer processor 61 may be implemented by the computer processor 21 of the distribution user device 20 or by the computer processor of the viewing user device 10, for example.

In the above-described embodiment, the viewing user device 10 that views the moving image and the distribution user device perform rendering based on the animation configuration data, thereby generating moving image data of the moving image including the distribution user's character object. That is, in the above-described embodiment, the image of the moving image including the character object of the distribution user is generated by the viewing user device 10 of the user who views the moving image or the distribution user device. Rendering for generating an image of a moving image may be performed by a device other than the viewing user device 10 that views the moving image or the broadcasting user device. For example, the server 60 may perform rendering for generating a video requested to be viewed, and transmit the video data generated by this rendering to the viewing user device 10 or the distribution user device that requested the viewing. . In this case, the viewing user device 10 and the distribution user device that have received the video data of the video to be viewed from the server 60 can output the received video data to a display or speaker without rendering. Rendering of the video to be viewed may be performed in the distribution user device of the distribution user who distributes the video. In this case, rendering is performed in the distribution user device of the distribution user who distributes the moving image, and the moving image data generated by this rendering is transmitted via the server 60 or directly to the viewing user device 10 that requested to view the moving image and It is sent to the broadcasting user equipment.
