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.

An outline of a video distribution system according to an embodiment of the present invention will be described with reference to FIG. 1. FIG. 1 is a block diagram showing an outline of a moving image distribution system 1 according to an embodiment of the present invention. As shown in the figure, the moving image distribution system 1 includes a client device 10 and a server device 20. Although only one client device 10 is shown in FIG. 1 for simplification of illustration, the moving image distribution system 1 can include a plurality of client devices 10. The server device 20 is configured to deliver a moving image. The client device 10 is configured to play a moving image distributed from the server device 20. The viewing user can view the moving image delivered from the server device 20 by using the client device 10. As will be described later, the server device 20 may be configured to distribute a moving image including an animation of a character object of a distribution user.

The viewing user can send a participation request for displaying his / her character object on the moving image to the server device 20 while the viewing moving image is being viewed by the client device 10. The server device 20 determines whether or not to display the character object of the viewing user in the moving image based on the participation request. In response to this determination, the server device 20 can generate a moving image so as to include the character object of the viewing user, and can distribute the moving image including the character object of the viewing user. In this way, the viewing user can participate in the moving image distributed from the server device 20 via his / her character object. Of a plurality of viewing users, a viewing user whose character object is displayed in the video being distributed, that is, a viewing user who participates in the video via his / her character object may be referred to as a participating user. There may be an upper limit on the number of participating users who are allowed to participate in the video. The server device 20 can select a maximum number of participating users or less from a plurality of viewing users who have requested participation.

Participating users can use the client device 10 to send a co-starring request for applying for co-starring with the distribution user to the server device 20. Upon receiving the co-starring request, the server device 20 determines whether or not to allow co-starring between the participating user and the distribution user who sent the co-starring request. When a decision is made to allow the participating user and the distribution user to co-star, the server device 20 generates a co-starring video including the character object of the distribution user and the character object of the participating user, and distributes the co-starring video. be able to. In this way, in the moving image distribution system 1, the distribution user and the viewing user can virtually co-star in the moving image via the respective character objects. When a distribution user and a viewing user virtually co-star in a video via their respective character objects, the video may be referred to as a co-star video. In addition, a viewing user who is co-starring with a distribution user in a co-starring video may be referred to as a guest user. The guest user may be one person or a plurality of people. When a plurality of guest users are determined, the distribution user can sequentially co-star with the plurality of guest users.

In one embodiment, the moving image distribution system 1 is configured to accept a co-starring request only from the viewing users who are allowed to participate in the moving image among the viewing users who view the moving image. For example, the function for making a co-starring request is activated in the client device 10 of the participating user whose participation request is accepted. As a result, the co-starring request can be accepted only from the participating users among the viewing users. Even if the number of viewing users increases, the number of co-starring requests received from the client device 10 can be suppressed.

The server device 20 determines whether or not the viewing user can participate based on the participation request from the viewing user, and then notifies all the viewing users who have made the participation request whether or not the participation in the video is permitted. May be configured not to send. Since the delivered video contains the character object of the viewing user who is allowed to participate, the viewing user can watch the video by himself / herself without receiving the notification indicating whether or not the viewing user is allowed to participate in the video. It is possible to know whether or not one's participation request is permitted based on whether or not the character object of is included. As described above, in one embodiment, since the information indicating whether or not the viewing user is permitted to participate in the video is included in the video, all the viewing users who have requested the participation other than the video are included. No notification is sent to indicate whether or not the viewing user is allowed to participate in the video. As a result, in the video distribution system 1, it is not necessary to send a notification indicating whether or not the viewing user is allowed to participate in the video to all the viewing users who have requested participation, separately from the distribution of the video. A notification indicating that participation may be permitted may be transmitted to the client device 10 of the participating user who is permitted to participate in the moving image among the viewing users. The client device 10 of the participating user may activate the function for the participating user to make a co-starring request in response to receiving the notification indicating that the participation is approved.

After the server device 20 determines whether or not the participating user and the distribution user can co-star based on the co-starring request from the participating user, the co-starring is permitted to the participating user (guest user) who is permitted to co-star. May be configured to send a permission notice. By receiving the permission notification, the guest user can know that he / she can co-star with the character object of the distribution user in the video. The guest user can prepare for the co-starring after being notified that the co-starring is permitted. Preparations for co-starring may include, for example, the purchase of additional content (eg, avatar parts) to enrich the depiction of one's character object (eg, avatar) displayed in the video. The server device 20 may be configured to send a disapproval notice notifying that the co-starring is not permitted to the participating users who have made the co-starring request and the co-starring is not permitted.

According to the video distribution system 1, a notification indicating whether or not the participation request is permitted is not transmitted to all the viewing users who have made the participation request other than the video to be distributed. As a result, the processing load on the server device 20 can be reduced, and an increase in communication traffic can be suppressed. On the other hand, in one embodiment, the guest user is notified of the permission notification indicating that the co-starring is permitted based on the co-starring request, so that the guest user can prepare for the co-starring with the distribution user. Since the guest user is a user who has been granted a participation request and a co-starring request among all the viewing users, the number is smaller than the total number of viewing users who make a participation request. The processing load required for generation and transmission is less than when a notification is transmitted to the entire viewing user.

A moving image distribution system according to an embodiment will be described with reference to FIGS. 2 to 6. FIG. 2 is a block diagram showing a video distribution system 1 according to an embodiment, and FIG. 3 is a schematic diagram schematically showing equipment of a studio in which a video distributed by the video distribution system 1 is produced. 4 and 5 are diagrams for explaining the information stored in the moving image distribution system 1, and FIG. 6 is a diagram for explaining the information included in the co-starring request.

The actor device 91 may be an LED (Light Emitting Diode) or a perceptual display device. LEDs and perceptual display devices can generate visual stimuli. The perceptual display device may be an electrical tactile display that drives the nerve axons under the skin by the current flowing from the electrodes.

In the illustrated embodiment, the supporter computer 40 is installed in a room next to the studio room R. Since the room in which the supporter computer 40 is installed and the studio room R are separated by a glass window, the operator of the supporter computer 40 (sometimes referred to as "supporter" in the present specification) can visually recognize the actor A1. .. In the illustrated embodiment, the supporter B1 and the supporter B2 are present as operators of the supporter computer 40.

The supporter computer 40 may be configured so that the settings of the components of the studio unit 30 can be changed according to the operations of the supporter B1 and the supporter B2. The supporter computer 40 can, for example, set the scanning interval by the base station 35a and the base station 35b, set the position or orientation of the digital camera 36a and the tracking sensor 36b, and change various settings of various devices other than these. .. The switching of the active sensor described later can be executed based on the operation of the supporter computer 40 by the supporter B1 and the supporter B2. At least one of the supporter B1 and the supporter B2 can input a message to the supporter computer 40 and display the input message on the display 39.

The components and functions of the studio unit 30 shown in FIG. 3 are exemplary. The studio unit 30 applicable to the present invention may include various components (not shown). The studio unit 30 may include a projector. The projector can project a moving image delivered to the client device 10a or other client devices onto the screen S.

On the other hand, the shooting for generating the delivered moving image may be performed by a simpler facility. For example, an information processing terminal such as a smartphone generates face motion data, which is a digital expression of the facial movement of an actor, and based on the face motion data, the facial expression moves in synchronization with the movement of the facial expression of the actor, but the body is You may generate an animation of a non-moving character object. Such generation of face motion data may be performed by the client device 10a to the client device 10c. In order to generate face motion data, application software having an instruction set that realizes a function for generating face motion data may be downloaded and installed in the client devices 10a to 10c. Application software having a function of generating such face motion data may be referred to as "distribution application software" or "distribution application". The distribution application and the above-mentioned viewing application may be separate application software, or a single application software may have both the function of the distribution application and the function of the described viewing application. The face motion data can include tracking data of the posture of the head of the actor, feature points which are digital representations of the feature points of the face of the actor, and blended face data expressing the deformation rate thereof. An information processing terminal such as a smartphone may create an image that exaggerates the facial expression of the actor based on the face motion data, and superimpose the image on the face of the character object. When generating an animation of a character object based on face motion data, motion sensors 31a, 31b, 31c, 31d, 31e, and 31f, a base station 35a, 35b, and a digital camera 36a for detecting the movement of the actor's body. Is not required, so it is possible to generate an animation of a character object with simpler equipment. If the motion sensors 31a, 31b, 31c, 31d, 31e, and 31f, the base stations 35a, 35b, and the digital camera 36a are unnecessary, the character object may be generated at a place other than the studio room R, for example, at the actor's home. Because it can be done, convenience is improved.

Next, in one embodiment, the information stored in the storage 23 will be described. In the illustrated embodiment, the storage 23 stores model data 23a, object data 23b, user data 23c, avatar data 23d, and various information necessary for generation and distribution of distribution moving images other than the above.

The model data 23a is model data for generating a character animation. The model data 23a may be three-dimensional model data for generating a three-dimensional animation, or may be two-dimensional model data for generating two-dimensional model data. The model data 23a includes, for example, rig data indicating the skeleton of the character (sometimes referred to as “skeleton data”) and surface data indicating the shape and texture of the surface of the character. The model data 23a can include a plurality of model data different from each other. The plurality of model data may have different rig data from each other, or may have the same rig data. The plurality of model data may have different surface data from each other, or may have the same surface data.

The object data 23b includes asset data for constructing a virtual space constituting a moving image. The object data 23b is data for drawing the background of the virtual space constituting the moving image, data for drawing various objects displayed in the moving image, and various objects displayed in the moving image other than these. Contains data. The object data 23b may include object position information indicating the position of the object in the virtual space.

In addition to the above, the object data 23b may include a gift object to be displayed in the moving image based on a display request from the viewing user of the client devices 10a to 10c. Gift objects can include effect objects, regular objects, and decorative objects. The viewing user can purchase the desired gift object.

The effect object is an object that affects the impression of the entire viewing screen of the distributed moving image, and is, for example, an object that imitates confetti. The object imitating confetti may be displayed on the entire viewing screen, whereby the impression of the entire viewing screen before and after the display can be changed. Effect objects may appear to overlap with character objects, but differ from decorative objects in that they are not displayed in association with a particular part of the character object.

A normal object is an object that becomes a digital gift from a viewing user to an actor (for example, actor A1) or a character in a moving image, for example, an object that imitates a stuffed animal or a bouquet. In one aspect, the normal object is displayed on the screen of the moving image so as not to come into contact with the character object. In one aspect, the normal object is displayed on the screen of the moving image so as not to overlap with the character object. Ordinary objects may appear to overlap objects other than character objects in virtual space. Ordinary objects may appear to overlap with character objects, but differ from decorative objects in that they are not displayed in association with a particular part of the character object. In one aspect, when the normal object is displayed overlapping with the character object, the normal object overlaps with a part other than the head including the face of the character object and does not overlap with the head of the character object. Is displayed.

A decorative object is an object that is displayed on the screen in association with a specific part of the character object. In one embodiment, the decorative object displayed on the screen in association with a specific part of the character object is displayed on the screen so as to be in contact with the specific part of the character object. In one aspect, the decorative object displayed on the screen in association with a particular part of the character object is displayed on the screen so as to cover part or all of the particular part of the character object.

The decorative object is, for example, an object that can be attached to accessories (catching, necklace, earrings, etc.), clothes (T-shirt, etc.), costumes, and other character objects attached to the character object. The object data 23b corresponding to the decorative object may include mounting position information indicating which part of the character object the decorative object is associated with. The mounting position information of a certain decorative object can indicate to which part of the character object the decorative object is mounted. For example, when the decorative object is a headband, the mounting position information of the decorative object may indicate that the decorative object is mounted on the "head" of the character object. When the decorative object is a T-shirt, the mounting position information of the decorative object may indicate that the decorative object is mounted on the "body" of the character object.

Each gift object may have a display time set according to its type. In one aspect, the display time of the decorative object may be set longer than the display time of the effect object and the display time of the normal object. For example, the display time of the decorative object may be set to 60 seconds, the display time of the effect object may be set to 5 seconds, and the display time of the normal object may be set to 10 seconds.

The object data 23b may include a list showing gift objects owned by the user of the moving image distribution system 1. In the possession list, an object ID that identifies the gift object possessed by the viewing user may be stored in association with the user's account information. The user's account information is, for example, a user ID that identifies the user. This user may include, for example, the first viewing user to the third viewing user of the client device 10a to the client device 10c.

As shown in FIG. 4, the user data 23c can include account information of each user (for example, a viewing user) of the video distribution system 1 and avatar information regarding the avatar used by each user. In other words, the storage 23 can store avatar information about avatars used by each user and information about users other than these, in association with the account information of each user of the video distribution system 1. The account information of a user is, for example, a user ID that identifies the user. The user ID of the user may be issued when the user registers for use in the moving image service provided by the server device 20 by using the client device 10a to the client device 10c. A common user ID may be used between the case where the service of the server device 20 is used by using the viewing application and the case where the service of the server device 20 is used by using the distribution application, or the viewing application is used. A different user ID may be used depending on whether the service of the server device 20 is used or the service of the server device 20 is used by using the distribution application. When different user IDs are used for using the service of the server device 20 using the viewing application and using the service of the server device 20 using the distribution application, the viewing application of the same user The user ID for using the service (viewing user ID) and the user ID for using the distribution application (distribution user ID) may be stored in association with each other. The service of the server device 20 that can be received by using the viewing application is, for example, a video viewing service distributed from the server device 20. The service of the server device 20 that can be received by using the distribution application is, for example, a service that distributes a moving image including its own character object.

The avatar information of a certain user is, for example, an avatar ID that identifies the avatar used by the user in the video distribution system 1. The avatar ID is assigned to the user when the user registers the avatar. The registration of the avatar is performed by the user selecting the head, hairstyle, clothes, accessories, and other parts constituting the avatar. The registration of the avatar may be performed by the client devices 10a to 10c in which the distribution application is installed. That is, the registration of the avatar may be performed by executing the function of the distribution application. In one embodiment, the avatar registration is performed by the client device in which the distribution application is installed among the client devices 10a to 10c, and may not be executed from the client device in which the distribution application is not installed. The registration of the avatar may be performed by application software (hereinafter, may be referred to as "avatar creation application") having a function of creating, editing, and / or registering an avatar different from the distribution application. Even when the avatar is registered by the distribution application and / or the avatar creation application, as described with reference to FIG. 3, an avatar ID that identifies the avatar is assigned, and the avatar ID is associated with the user ID of the user. It may be managed as user information. After registering the avatar, the user can change the avatar. For example, after the avatar is registered, some or all of the parts of the avatar can be changed. For example, even after registration, the avatar's hairstyle, possessed items, and other parts that make up the avatar can be changed.

In one embodiment, it is distributed from the viewing history data indicating the viewing history of the user, the evaluation data indicating the evaluation of the user by another user, and the server device 20 other than these, in association with the user ID of the user. Data related to the video may be included.

As shown in FIG. 5, the avatar data 23d can include avatar identification information of the avatar used by the user in the moving image distribution system 1 and avatar display information for displaying the avatar in the moving image. In other words, the storage 23 may store the avatar display information for displaying the avatar in association with the avatar identification information of the avatar. The avatar identification information is, for example, an avatar ID that identifies the avatar. Avata is displayed in a moving image as, for example, an image imitating a human or an animal. The avatar display information is information used to display the avatar in the moving image. The avatar information includes, for example, parts information showing images of the head, hairstyle, facial parts (eyes, nose, mouth, etc.), torso, clothes, accessories, items, and other parts that make up avatar. included. The user can register his / her own avatar by selecting a favorite part image. The avatar display information may include 2D display information for displaying the avatar in the moving image in 2D and 3D display information for displaying the avatar in the moving image in 3D. In the 3D display information, part information showing the image of the part for displaying the avatar three-dimensionally in the video, rig data for expressing the movement of the avatar in three dimensions, and other avatars are displayed three-dimensionally. Contains known information used to do this.

Next, the functions realized by the computer processor 21 will be described more specifically. The computer processor 21 executes a computer-readable instruction included in the distribution program to execute a video generation unit 21a, a video distribution unit 21b, a participation request processing unit 21c, an avatar display unit 21d, an avatar control unit 21e, and a co-starring request. It functions as a processing unit 21f. At least a part of the functions realized by the computer processor 21 may be realized by a computer processor other than the computer processor 21 of the moving image distribution system 1. At least a part of the functions realized by the computer processor 21 may be realized by, for example, a computer processor mounted on the supporter computer 40 or another computer processor (not shown).

The moving image generation unit 21a constructs a virtual space and generates moving image information (three-dimensional moving image data) for drawing a drawing area of the virtual space defined based on the setting information of the virtual camera. The setting information of the virtual camera may include, for example, the position of the virtual camera in the virtual space, the gaze position, the gaze direction, and the angle of view. The moving image information can be generated based on the object data 23b and other data as needed. The moving image generation unit 21a renders the three-dimensional moving image data to generate a plurality of moving image frames. This moving image frame is generated at a predetermined frame rate. The virtual space constructed by the moving image generation unit 21a is defined as, for example, a spherical three-dimensional space that surrounds the center position thereof. The position in the virtual space can be specified by the coordinate value in the three-dimensional global coordinate system set in the virtual space.

The moving image information generated by the moving image generation unit 21a may include information about the character object of the actor A1 in the drawing area of the virtual space. The moving image information may be generated so as to reflect the movement of the actor A1 in real time. The information about the character object of the actor A1 may include body motion data of each part of the body of the actor A1 and face motion data which is a digital representation of the movement of the face of the actor A1. The body motion data is generated based on, for example, the detection information of each of the motion sensors 31a to 31f. Body motion data is generated at any time over time. Body motion data may be generated at predetermined sampling time intervals. In this way, the body motion data can express the movement of the body of the actor A1 as digital data in time series. In the illustrated embodiment, since the motion sensors 31a to 31f are attached to the left and right limbs, hips, and head of the actor A1, the motion sensors 31a to 31f of the actor A1 are based on the detection information of the motion sensors 31a to 31f. It is possible to digitally express the position and orientation of the whole body over time. The body motion data can define, for example, the position and rotation angle of the bones constituting the rig data included in the model data 23a. The face motion data is generated based on, for example, the image pickup data of the camera 37a. Face motion data is generated at any time over time. For example, face motion data may be generated at predetermined sampling time intervals. In this way, the face motion data can digitally represent the facial movement (change in facial expression) of the actor A1 in time series. By applying the body motion data and the face motion data to the predetermined model data included in the model data 23a, an animation of a character object that moves in the virtual space and whose facial expression changes may be generated. In this way, the moving image information may include information representing the animation of the character object that moves in synchronization with the movement of the body and facial expression of the actor A1 based on the body motion data and the face motion data related to the actor A1. The moving image generation unit 21a can generate a sequence of moving image frames representing an animation of a character object that moves in synchronization with the movement of the body and facial expression of the actor A1 based on the moving image information obtained as described above. The moving image generation unit 21a may synthesize the sound of the actor A1 acquired from the microphone of the studio unit 30 with the generated moving image.

The moving image generation unit 21a can load the avatar display information necessary for displaying the avatar for the avatars that may participate in the moving image before the distribution of the moving image. Among the avatar display information, the moving image generation unit 21a can load the 3D display information that takes a long time to load and has a large processing load for loading. This loaded avatar display information can be referred to when the avatar is displayed in the video based on the participation request from the user. The use of the loaded avatar display information when displaying the avatar in the moving image will be described later.

The moving image distribution unit 21b distributes a sequence of moving image frames generated by the moving image generation unit 21a. The moving image frame may be compressed and encoded by a moving image distribution unit 21b by a predetermined coding method such as MPEG-4, or the compressed and encoded moving image frame may be distributed. In the present specification, when referring to the distribution of a moving image, it may mean the distribution of a sequence of moving image frames generated as described above.

The delivered moving image is received by the client devices 10a to 10c via the network 15, and is played back in the client devices 10a to 10c. This moving image may be delivered to a client device (not shown) installed in the studio room R, and may be projected from this client device onto the screen S via a short focus projector. Further, this moving image may be delivered to the supporter computer 40. As a result, the supporter B1 and the supporter B2 can confirm the viewing screen of the delivered moving image.

A user involved in the generation and / or distribution of a moving image distributed from the moving image distribution unit 21b may be referred to as a distribution user. In the above example, the moving image delivered from the server device 20 includes the character object generated based on the body motion data and the face motion data of the actor A1, and the cooperation of the supporters B1 and the supporters B2 is required as necessary. Obtained and delivered. Therefore, not only the actor A1 but also the actor A1, the supporter B1, and the supporter B2 may be collectively referred to as a “delivery user”.

7a and 7b show an example of displaying a moving image generated by the moving image generation unit 21a and distributed by the moving image distribution unit 21b. 7a and 7b show an example of displaying a moving image distributed by the moving image distribution unit 21b and reproduced by the client devices 10a to 10c. Hereinafter, the images of FIGS. 7a and 7b will be described on the assumption that they are displayed on the client device 10a used by the first viewing user. The image shown in FIG. 7a may be displayed on the display of the client device 10a by executing the viewing application on the client device 10a and playing back the moving image distributed from the server device 20.

As shown in the figure, the image 60a includes a character object 51, a floor object 54a on which the character object 51 stands, and a screen object 54b that defines the rear end of the stage. Further, the image 60a includes a display object 65 on which a comment from a viewing user and a system notification are displayed. The character object 51 is depicted so as to move in the moving image in synchronization with the movement of the body and facial expression of the actor A1. In one embodiment, the character object 51, the floor object 54a, and the screen object 54b may be objects included in the moving image frame, and the display object 65 may be an object not included in the moving image frame. The display object 65 may be an object generated by the function of the viewing application executed by the client device 10 without being based on the data included in the moving image frame transmitted from the server device 20.

In the image 60a, in addition to each object arranged in the virtual space 50, an operation button for accepting a user's operation may be displayed. In the example shown in FIG. 7a, the image 60a includes a gift button 61 for performing gifting, an evaluation button 62 for providing an evaluation, and a participation request button 63 for allowing the avatar to participate. It has been. Operation buttons other than these may be displayed on the image 60a. These operation buttons may be objects generated by the function of the viewing application executed by the client device 10 without being based on the data included in the moving image frame transmitted from the server device 20.

The gift button 61 is displayed on the image 60a so as to be selectable by operating the client device 10a on which the image 60a is displayed. The gift button 61 can be selected, for example, by tapping the area of the touch panel of the client device 10a where the gift button 61 is displayed. In one embodiment, when the gift button 61 is selected, the image 60a displays a window for selecting a gift to be given (gifted) to the distributor who is distributing the video being viewed. The user of the client device 10a can purchase and select a gift to be gifted from the gifts displayed in the window. In another embodiment, in response to the gift button 61 being selected, the image 60a displays a window containing a list of purchased gifts and / or a list of selectable gifts. In this case, the user watching the video can select the gift to be gifted from the gifts displayed in the window. In one embodiment, a gifting request may be sent to the server device 60 depending on the selection of the gift button 61 on the client device 10. The gifting request may include gift identification information (gift ID) that identifies the gift object corresponding to the gift to be gifted. In this way, the viewing user who is watching the video can give a desired gift to the distribution user who is distributing the video by selecting the gift button 61.

The server device 20 receives a gifting request from the user's client device 10a and performs processing according to the request. As described above, the user who is watching the moving image can send the gifting request to the server device 20 by operating his / her own client device. In one aspect, when the server device 20 receives the gifting request, the server device 20 identifies the gift object to be gifted based on the gifting request, and performs display processing according to the specified gift object. As mentioned above, the gift object may include an effect object, a normal object, and a decorative object. When the gift object specified by the gifting request is an effect object, the server device 20 performs a process for including the effect object in the moving image frame. For example, when a gifting request is made for an effect object corresponding to confetti, the server device 20 includes an effect object indicating confetti in the moving image frame based on the gifting request. As a result, the confetti is depicted in the image 60a. In one aspect, when the server device 20 receives a gifting request for a specific normal object, the server device 20 performs a process for including the normal object specified by the gifting request in the moving image frame. For example, when a gifting request is made for a normal object showing a teddy bear, the server device 20 includes the normal object showing the stuffed bear in the moving image frame. As a result, the teddy bear is depicted in the image 60a.

In one aspect, when the server device 20 receives a gifting request for a specific decorative object from the viewing user, the server device 20 adds the decorative object specified by the gifting request to the candidate list. This candidate list is displayed, for example, on the display of the supporter computer 40. The supporter B1 and the supporter B2 can select a decorative object to be displayed in the moving image from the candidate list displayed on the display of the supporter computer 40. The server device 20 includes the selected decorative object in the moving image frame. As a result, the decorative object is depicted in the image 60a. The selected decorative object is displayed in the image 60a in association with a specific part of the character object 51. For example, when the decorative object is an object indicating a headband, the decorative object may be attached to the head of the character object 51. The decorative object may be displayed in the image 60a so as to accompany the movement of the specific portion of the character object. For example, when the head of the character object 51 to which the headband is attached moves, the selection decoration object indicating the headband is attached to the head of the character object 51 as if the headband is attached to the head of the character object 51. It works.

The evaluation button 62 is displayed on the image 60a so as to be selectable by the user who uses the client device 10a. The evaluation button 62 can be selected, for example, by tapping the area of the touch panel of the client device 10a where the evaluation button 62 is displayed. When the evaluation button 62 is selected by the user who is watching the video, a positive evaluation is given to the distribution user (for example, actor A1) who distributes the video, or a positive evaluation is made to the distributed video. Evaluation update information indicating that may be transmitted to the server device 60. By selecting the evaluation button 62, evaluation information indicating that the moving image has been negatively evaluated may be transmitted to the server device 60.

The participation request button 63 is displayed on the image 60a so as to be selectable by the viewing user who uses the client device 10a. The participation request button 63 may be selected, for example, by tapping the area of the touch panel of the client device 10a where the participation request button 63 is displayed. When the participation request button 63 is selected by the viewing user who is viewing the video, a participation request requesting that the viewing user's avatar participate in the video is transmitted to the server device 20. A user who has sent a participation request by selecting the participation request button 63 may be referred to as a "participation request user". The participation request from the participation request user may include the user ID of the participation request user and the avatar ID of the avatar of the participation request user. When the participation request button 63 is selected by a viewing user who has not registered his / her own avatar, a screen prompting the client device 10a to register the avatar may be displayed. In this case, the viewing user can register the avatar according to the guidance on the screen. The participation request button 63 may be displayed on the client device 10 of all viewing users.

The participation request processing unit 21c receives a participation request for the moving image being viewed from the client device 10a of the participation request user, and determines whether or not the participation request user's avatar can be displayed based on the participation request. There may be a maximum number of avatars that can participate in videos for which participation is requested. In this case, the participation request processing unit 21c can determine whether or not to participate based on the participation request so that the number is equal to or less than the upper limit. The participation request processing unit 21c, for example, accepts a participation request during the reception period before the video is distributed, and among a plurality of participation request users who have made the participation request, the participation request user is invited to participate in the video by the maximum number or less. Can be allowed. That is, the participation request processing unit 21c can select a plurality of participating users of the upper limit or less from the plurality of viewing users (participation request users) who have made the participation request. When the number of participation request users exceeds the upper limit, the participation request processing unit 21c may select a user having or less than the upper limit of the number of participation request users from a plurality of participation request users according to a predetermined algorithm. The participation request processing unit 21c can select, for example, users who are allowed to participate on a first-come, first-served basis or at random. The participation request processing unit 21c may determine whether or not the participation request user can participate based on the viewing history data, the evaluation data, and other data stored as the user data 23c. For example, based on the viewing history data, the participation requesting user who has a long viewing time may be more likely to be permitted to participate. Based on the viewing history data, the participation requesting user who has a large number of viewings may be more likely to be permitted to participate. In the present specification, a viewing user who is permitted to participate in a moving image by the participation request processing unit 21c may be referred to as a "participating user".

In one embodiment, the participation request processing unit 21c determines whether or not the viewing user can participate based on the participation request from the viewing user, and then permits all the viewing users who have made the participation request to participate in the video. It may be configured not to send a notification indicating whether or not it has been done. The participation request processing unit 21c may send a command for activating the co-starring function described later to the client device 10 of the participating user who is permitted to participate in the moving image. In one embodiment, the participation request processing unit 21c determines whether or not the viewing user can participate based on the participation request from the viewing user, and then refers to the client device 10 of the participating user who is permitted to participate in the video. While transmitting the above command, the client device 10 of the participating user who is permitted to participate in the video is configured not to send a notification indicating a decision on whether or not to participate in the video and neither of the above commands. Will be done.

When the participation requesting user is permitted to participate in the video, the avatar display unit 21d performs a process for including the avatar of the participating user who is permitted to participate in the video. For example, when the avatar of the first viewing user is included in the moving image, the avatar display unit 21d identifies the avatar ID associated with the user ID of the first viewing user by referring to the user data 23c, and then identifies the avatar ID associated with the user ID of the first viewing user. , The part information associated with the avatar ID is specified with reference to the avatar data 23d. The avatar display unit 21d constructs an avatar object representing the avatar of the first viewing user based on the specified part information. Further, the avatar display unit 21d determines the display position of the avatar object in the virtual space. The moving image generation unit 21a generates moving image information so that the avatar object constructed by the avatar display unit 21d is arranged at a determined position in the virtual space, and generates a moving image frame based on the moving image information. The moving image frame including the avatar object of the participating user generated in this way is transmitted to the client device 10 by the moving image distribution unit 21b.

The client device 10 can reproduce a moving image frame including an avatar object of a participating user. FIG. 7b shows a display example of a moving image including an avatar object of a participating user. As shown in FIG. 7b, the image 60b contains the avatar objects 56a-56c and 57a-57g of the participating users. In the following description, it is assumed that the avatar 56a is the avatar (avatar object) of the first viewing user among the plurality of avatar objects included in the image 60b. The virtual camera used for drawing the image 60b shown in FIG. 7b directs the direction of the character object 51 at a position farther from the character object 51 than the virtual camera used for drawing the image of FIG. 7a. It is arranged so that it faces. Therefore, in the image 60b, a wider range of the virtual space including the character object 51 is drawn than in the image 60a.

As shown in FIG. 7b, the emotion button 68 may be displayed superimposed on the image 60b. The emotion button 68 is a button for the viewing user to express emotions when viewing a moving image. The emotion button 68 may be superimposed and displayed on the moving image frame distributed from the server device 20. That is, the emotion button 68 does not have to be an object arranged in the virtual space. By selecting the emotion button 68, the viewing user can select that he / she was impressed by the moving image, that he / she could not sympathize with the moving image, and the emotions of the viewing user other than these. The emotion button 68 has an applause button for selecting the emotion of being impressed by the video, a question mark button for indicating that the video could not be empathized, a surprise button for indicating that the video was surprised, and other buttons. Can include buttons. Each of the emotion buttons 68 may include a symbol or graphic display representing the emotion selected by the emotion button 68. For example, the applause button may contain a graphic representation of the clapping hand, the question mark button may contain a question mark display, and the surprise button may contain an exclamation mark. A display may be included. The emotion button 68 can be selected, for example, by tapping the area of the touch panel of the client device 10a where the emotion button 68 is displayed. When the emotion button 68 is selected by the first viewing user who is viewing the moving image, the emotion display request is transmitted to the server device 20. The emotion display request may include emotion identification information indicating the type of button (applause button, question mark button, surprise button, etc.) selected by the first viewing user among the emotion buttons 68. By selecting the emotion button 68, a plurality of buttons (applause button, surprise button, etc.) associated with the emotion button 68 may be displayed in a pop-up manner. When a plurality of buttons associated with the emotion button 68 are displayed in a pop-up, the user can select a button that matches his / her emotion from the plurality of buttons displayed in the pop-up. The emotion button 68 may be displayed when the user's avatar is participating in the video, and may not be displayed when the user's avatar is not participating in the video.

The avatar control unit 21e may receive an emotion display request from the first viewing user and control the movement of the first viewing user in the virtual space based on the emotion display request. For example, when the emotion display request is transmitted by the first viewing user selecting the applause button, which is a kind of emotion button, the avatar control unit 21e is based on the emotion display request of the first viewing user. The action of applauding the avatar 56a can be performed. When the control to make the avatar 56a applaud is performed based on this emotion display request, if the avatar 56a is included in the drawing area, the animation in which the avatar 56a is clapping is expressed in the moving image. May be. On the contrary, when the avatar 56a is not included in the drawing area, the sound of the avatar 56a clapping may be expressed in the moving image, but the clapping animation may not be displayed. In one embodiment, the emotion button 68 may be displayed in the video being viewed by the user only when the user's avatar is displayed in the video. For example, when the image 60a shown in FIG. 7a is displayed on the client device 10a of the first viewing user, the avatar 56a of the first viewing user is not displayed in the image 60a, so this image. The 60b does not have to include the emotion button 68. On the contrary, when the client device 10a of the first viewing user includes the image 60b shown in FIG. 7b, the avatar 56a of the first viewing user is included in the image 60b. Therefore, the emotion button 68 may be included in this image 60b.

In this way, based on the emotion display request from the user, the user's avatar makes a movement such as applause in the moving image. The emotion display request is a kind of operation instruction for instructing the operation of the avatar. In another embodiment, in addition to the emotion button, an operation instruction button for instructing the operation of the avatar may be included in the image. The operation instruction button is a button for instructing the operation of the avatar. The operation instruction button can be used, for example, to instruct an operation of jumping, an operation of waving a hand, an operation of waving a glow stick, and other operations. When the operation instruction button is selected, the operation instruction request is transmitted to the server device 20. In the server device 20, the avatar can be made to perform an operation based on an operation instruction request.

Next, a co-starring function in which a viewing user and a distribution user co-star in a moving image via their respective virtual characters will be described. As shown in FIG. 7b, when the first viewing user is permitted to participate in the moving image, the co-starring application button 64 is displayed on the client device 10 used by the first viewing user. The co-starring application button 64 requests that the viewing user's avatar be displayed together with the character object 51, that is, the viewing user and the distribution user co-star through the viewing user's avatar and the distribution user's character object 51. It is a button for. The co-starring application button 64 is superimposed and displayed on the image 60b so as to be selectable by the first viewing user who uses the client device 10a. The co-starring application button 64 can be selected, for example, by tapping the area of the touch panel of the client device 10a where the co-starring application button 64 is displayed. When the co-starring application button 64 is selected by the first viewing user who is viewing the moving image, a co-starring request for co-starring the avatar 56a of the first viewing user with the character object 51 is transmitted to the server device 20. The client device 10a of the first viewing user displays a message 66a indicating that the co-starring request has been made, as shown in FIG. 7c, in response to the co-starring request being transmitted to the server device 20. May be good.

In one embodiment, the client device 10 may display the co-starring application button 64 in response to receiving a command for activating the co-starring function from the participation request processing unit 21c. As described above, this command is transmitted from the server device 20 to the client device 10 of the participating user who is permitted to participate in the moving image. The client device 10 does not have to display the co-star application button 64 until it receives a command for activating the co-star function from the participation request processing unit 21c. The co-star application button 64 is displayed in a state in which it cannot be selected by the user until a command for activating the co-star function is received from the participation request processing unit 21c, and can be selected by the user according to the reception of the command. May be done.

When the co-starring request is received by the server device 20, the co-starring request processing unit 21f determines whether or not to allow co-starring between the viewing user (participating user) who made the co-starring request and the distribution user. The co-starring request processing unit 21f can determine whether or not co-starring is possible by using a predetermined algorithm based on various information about the viewing user who made the co-starring request. The co-starring request processing unit 21f determines, for example, whether or not the evaluation from other users for the viewing user who has made the co-starring request is higher than the predetermined standard by referring to the user data 23c, and the evaluation for the viewing user is evaluated. If it is higher than the standard, the co-starring request from the viewing user can be permitted. On the contrary, when the evaluation of the viewing user from other users is lower than the predetermined criterion, the co-starring request from the viewing user can be rejected. A viewing user (participating user) for whom a co-starring request is permitted may be referred to as a "guest user".

The co-starring request processing unit 21f inquires of the distribution user whether or not to allow the co-starring application from the viewing user in response to the reception of the co-starring request from the viewing user, and determines whether or not the co-starring is possible according to the response. You may. When the co-starring request processing unit 21f receives the co-starring request from the first viewing user, it may generate a display request user list including the first viewing user and present the display request user list to the distribution user. The display request user list for a certain video is a list format of information (for example, user ID, user name, nickname, avatar ID, or other information) that identifies the user (or the avatar of the user) who made the co-starring request. It may be indicated by. The display request user list does not have to include all the users who sent the co-starring request. For example, the display request user list may include only the users who have sent the co-starring request and the 3D display information of the avatar of the user has already been loaded. Such a display request user list does not include information that identifies a user who has sent a co-starring request to which the 3D display information of the avatar of the user is not loaded. 3D display information is not loaded In order to perform 3D display of the avatar, it is necessary to load the 3D display information at runtime, which consumes a lot of processing resources of the server device 20. By including only the user who uses the loaded avatar in the 3D display information in the co-starring request, it is possible to avoid the runtime load.

The co-starring request processing unit 21f can transmit the display request user list to the supporter computer 40. The supporter B1 and the supporter B2 can select an avatar user who is allowed to be displayed together with the character object from the display request user list displayed on the display of the supporter computer 40. The display request user list may be displayed on the display 39 of the studio room R. The actor A1 may select an avatar user to be displayed together with the character object 51 from the display request user list by operating the controller 33a or the controller 33b.

In one embodiment, the user may be deleted from the display request user list in response to the selection of a user from the display request user list. In another embodiment, the user may be deleted from the display request user list in response to the end of the co-starring display of the avatar of a user. As a result, it is possible to prevent the avatar that has been co-starred once from being repeatedly co-starred.

In one embodiment, even if a supporter or a distribution user instructs to select a user to be co-starred from the display request list while a user is co-starred, the co-starred display of the selected user's avatar is immediately displayed. It does not have to be done in. Further, the selected user may not be deleted from the display request list until the co-starring display is performed.

When the co-starring request processing unit 21f receives co-starring requests from a plurality of participating users, the co-starring request processing unit 21f may select a plurality of guest users having a predetermined upper limit or less from the plurality of participating users.

In one embodiment, the co-starring request processing unit 21f is a client device 10 of the participating user (that is, a guest user) when co-starring between the participating user and the distribution user is permitted based on the co-starring request from the participating user. You may send a permission notice notifying that the co-starring is permitted. Upon receiving the permission notification, the client device 10 may display a message 66b indicating that the co-starring is permitted based on the permission notification on the display, as shown in FIG. 7d. The message 66b displayed based on this permission notification allows the guest user to know that his / her avatar is included in the co-starring video and delivered. In addition to the message 66b, the client device 10 can notify the guest user that the icon display, voice notification, vibration notification, and permission notification have been received by a method other than these.

Upon receiving the permission notification from the server device 20, the client device 10 of the guest user can urge the guest user to purchase the avatar parts. For example, the client device 10 purchases avatar parts in response to receiving a permission notification from the server device 20.

When the permission notification is received from the server device 20 in the client device 10 of the guest user, the client device 10 can display a display prompting the purchase of the avatar parts. For example, the client device 10 can display a window for purchasing the avatar body or its parts on its display in response to receiving the permission notification from the server device 20. The guest user can select the purchase target from the avatar or its parts displayed in the window and actually purchase it. The window for purchasing the avatar or its parts may be displayed only on the client device 10 that has received the permission notification from the server device 20, or may be displayed on the other client devices 10. Upon receiving the permission notice, the client device 10 may display a window in which a different type of avatar or a part thereof can be purchased than before the permission notice was purchased. The client device 10 that has received the permission notification can display, for example, a window for purchasing an avatar or a part suitable for the co-starring moving image.

In one embodiment, when the permission notification is received from the server device 20 in the client device 10 of the guest user, the client device 10 may make the so-called gacha function available to the guest user. By using this gacha function, the guest user sends an acquisition request for the avatar or its parts to the server device 20, and the avatar or the guest user is given to the guest user by a predetermined algorithm based on the acquisition request in the server device. The part is selected. This selected avatar or its part is given to the guest user who made the acquisition request. In this way, the guest user can acquire a new avatar or a part thereof by using the gacha function. The gacha function for acquiring the avatar or its parts may be available only in the client device 10 that has received the permission notification from the server device 20, or may be available in other client devices 10. .. The client device 10 that has received the permission notification may be able to acquire a different type of avatar or a part thereof from before purchasing the permission notification by the gacha function.

In this way, the guest user can update his / her own avatar displayed in the co-starring video before the start of the co-starring by purchasing a new avatar or its parts or acquiring it by the gacha function.

In one embodiment, the co-starring request processing unit 21f includes the participating user (that is, the guest user) and the distribution user when co-starring between the participating user and the distribution user is permitted based on the co-starring request from the participating user. Generates a co-starring video that virtually co-stars. For example, the co-starring request processing unit 21f displays the guest user's avatar together with the character object 51 in the moving image. The co-starring request processing unit 21f can construct the guest user's avatar by the same processing as the avatar control unit 21e, and can arrange the guest user's avatar in the virtual space. In one embodiment, in the co-starring moving image including the avatar of the guest user to whom the co-starring request is permitted and the character object 51 of the distribution user, the avatar of the viewing user other than the guest user is not displayed. In this case, the co-starring request processing unit 21f arranges only the guest user's avatar among the plurality of viewing user's avatars in the virtual space. In the present specification, displaying the avatar of the guest user for whom the co-starring request is permitted together with the character object 51 of the distribution user is referred to as "co-starring display", and the avatar of the viewing user and the character of the distribution user for which the co-starring request is permitted are displayed. A moving image including the object 51 may be referred to as a "co-starring moving image".

A display example of the co-starring moving image is shown in FIG. 7e. The image 60e shown in FIG. 7e includes an avatar 56a of the first viewing user and a character object 51 that have made a co-starring request. In the image 60e shown in FIG. 7e, the avatar 56a of the first viewing user is displayed next to the character object 51. The image 60d may display a message 66c for notifying that the co-starring display has been performed.

When the avatar 56a of the first viewing user is displayed together with the character object 51 based on the co-starring request from the first viewing user, the avatar 56a may be displayed in 3D. As described above, the avatar 56a may be displayed in 2D in the image (for example, the image 60b) before the co-starring request is made. The display mode of the avatar 56a that was displayed in 2D before the co-starring request may be changed to 3D display in the co-starring display. Since the avatar 56a is displayed in 3D in the co-starring display, it is displayed on the client device 10a of the first viewing user only when the 3D display information about the avatar 56a is loaded before the time when the co-starring request is received. The co-starring application button 64 may be displayed on the image 60b.

In one embodiment, the co-star application button 64 is displayed in the image for the user who uses the avatar to which the 3D display information is loaded, and the co-star application is applied to the image for the user who uses the avatar to which the 3D display information is not loaded. By not displaying the button 64, it is possible to reduce the processing load of the server device 20 by preventing the runtime load of the 3D display information from occurring. In one embodiment, in order to avoid the occurrence of the processing load required for the runtime load, when the co-starring display of the avatar is received from the user, it is determined whether or not the 3D display information of the avatar has been loaded and the avatar has been loaded. The 3D display of the avatar may be performed only in the case of. In this case, the co-star application button 64 is displayed in the image for the user who uses the avatar to which the 3D display information is loaded, while the co-star application button 64 is displayed in the image for the user who uses the avatar to which the 3D display information is not loaded. By not displaying 64, it is possible to prevent unnecessary transmission of the co-starring request and occurrence of processing based on the co-starring request.

When the avatar is co-starred in the moving image, the effect related to the co-starring display of the avatar may be displayed. For example, it is possible to create an effect in which the spotlight is shining on the avatar so as to emphasize the avatar that is co-starred. The same or another effect can be displayed when the co-starring display of the co-starring display is terminated.

The co-starring request processing unit 21f may measure the elapsed time since the first viewing user's avatar 56a is displayed in the moving image together with the character object 51. The co-starring request processing unit 21f may display the elapsed time on the image 60d. In one embodiment, an upper limit of the time during which the character object 51 and the user's avatar are displayed together (the time during which the co-starring is displayed for a certain avatar) may be set based on the co-starring request. The co-starring request processing unit 21f may display the upper limit time on the image 60d. The co-starring request processing unit 21f calculates the remaining time during which the avatar 56a can be displayed based on the upper limit time and the elapsed time since the avatar 56a of the first viewing user is displayed in the moving image together with the character object 51. Then, the remaining time may be displayed on the image 60d. The elapsed time since the avatar 56a of the first viewing user is displayed in the moving image together with the character object 51, the upper limit of the display time set in the avatar 56a, and the remaining time during which the avatar 56a can be displayed are the client devices of the first viewing user. It may be included only in the image 60d displayed on the 10a, or may be included in the image 60d displayed on the client device of the first viewing user and other users. By setting an upper limit of the time during which the co-starring display is performed, it is possible to provide more viewing users with an opportunity to co-star with the distribution user. Further, by displaying the remaining time of the co-starring display during execution, it is possible to inform the viewing user of the time until the next avatar is co-starring displayed.

The co-starring request processing unit 21f can exclude the avatars participating in the video from the video based on the instructions from the video distribution user or other operators. The excluded avatar will not be displayed on the screen of the video. Similarly, the co-starring request processing unit 21f can exclude the co-starring avatar from the co-starring display based on the instruction from the video distribution user or other operators. The excluded avatar will not be displayed on the screen of the co-starring display. For example, the distribution user may perform an avatar who made an undesired comment in the video, an avatar who took an undesired action in the video, and an avatar which is not desirable to be allowed to participate in other videos from the video and / or co-starred. It can be excluded from the display screen.

In one embodiment, the avatar control unit 21e can control the movement of the guest user's avatar based on an instruction from the user. For example, the avatar control unit 21e can receive an emotion display request from a user of the avatar co-starring and control the behavior of the avatar based on the emotion display request. The avatar control unit 21e controls the movement of the avatar by using the face motion data and the body motion data transmitted from the client device 10 of the guest user who is co-starring with the distribution user in the co-starring video during the distribution of the co-starring video. You may do it. The avatar control unit 21e may make the avatar speak using the voice data transmitted from the client device 10 of the guest user who is co-starring with the distribution user in the co-starring video during the distribution of the co-starring video.

As shown in FIG. 6, the co-starring request may include at least one of message data and motion data in association with a user ID that identifies a participating user who makes a co-starring request. The avatar control unit 21e may utter a message corresponding to the message data in the moving image to the guest user avatar based on the message data included in the co-starring request. As this message, for example, a greeting such as "Hello" can be considered. A text message may be generated based on the message data, and the text message may be displayed in association with the avatar of the participating user who made the co-starring request. The message data may be data corresponding to a plurality of messages.

The motion data can include at least one of face motion data and body motion data. The motion data included in the co-starring request may be acquired by the sensor unit included in the client device 10, or may be acquired by a sensing device different from the client device 10. The avatar control unit 21e may control the movement of the guest user's avatar based on the motion data included in the co-starring request. The motion data is data representing, for example, the movement of the avatar in which the avatar waving his right hand to greet him. The motion data may be data representing a set of avatar movements. A set of avatar movements is, for example, a set of avatar waving and then the avatar bowing.

In one embodiment, for a participating user who has sent a co-starring request with the distribution user but the co-starring is rejected, an image (two-shot image) including the avatar of the participating user and the character object 51 of the distribution user is provided. You may give it. For example, when the co-starring request from the first viewing user is rejected, the co-starring request processing unit 21f generates the same video frame as the video frame generated when the co-starring request is permitted, and this video frame. The moving image file representing the above may be transmitted to the client device 10 of the first viewing user whose co-starring is refused. This moving image frame is transmitted only to the client device 10 of the first viewing user whose co-starring request is rejected, and is not delivered to the client device 10 of another viewing user. This video frame corresponds to, for example, the image 60e shown in FIG. 7e (however, the message 66c and the operation buttons 61, 62, 68 are not included. As a result, the participation with which the co-starring with the distribution user is refused is rejected. It is possible to provide the user with content for feeling the connection with the distribution user. The two-shot image with the character object 51 of the distribution user is requested to participate in the video, but the participation request is made. It may be sent to the rejected viewing user.

Subsequently, with reference to FIG. 8, a moving image distribution process according to one aspect will be described. FIG. 8 is a flow chart showing the flow of video distribution processing in one embodiment. In the video distribution process, it is assumed that the actor A1 is present in the studio room R.

First, in step S11, body motion data that is a digital representation of the body movement of the actor A1 and face motion data that is a digital representation of the face movement (facial expression) of the actor A1 are generated. The body motion data and face motion data are set in, for example, the detection information of the motion sensors 31a to 31f mounted on the actor A1, the image pickup information captured by the digital camera 36a, and the studio room R other than these as necessary. It is generated based on the information detected by various devices.

Next, in step S12, by applying the body motion data and face motion data of the actor A1 to the model data for the actor A1, an animation of a character object that moves in synchronization with the movement of the body and facial expression of the actor A1 is generated. Will be done.

Next, in step S13, three-dimensional moving image data including an image of the virtual space and an animation of a character object corresponding to the actor A1 is generated. This moving image information may include the sound of the actor A1. Further, the three-dimensional moving image data is rendered to generate a moving image. This moving image may be a sequence of moving image frames. This moving image is generated, for example, by the moving image generation unit 21a described above.

Next, the process proceeds to step S14, and the moving image generated in step S13 is delivered. This moving image is distributed to the client devices 10a to 10c and other client devices via the network 15. This moving image may be delivered to the supporter computer 40 and may be projected on the screen S in the studio room R. The moving image is continuously distributed over a predetermined distribution period. The distribution period of the moving image may be set to, for example, 30 seconds, 1 minute, 5 minutes, 10 minutes, 30 minutes, 60 minutes, 120 minutes, and any other time.

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 supporter computer 40 has given an instruction to end the distribution, or other conditions. If the end condition is not satisfied, the processes of steps S11 to S14 are repeatedly executed, and the distribution of the moving image including the animation synchronized with the movement of the actor A1 is continued. If it is determined that the end condition for the video is satisfied, the distribution process of the video is terminated.

Subsequently, with reference to FIG. 9, the participation request processing according to one aspect will be described. FIG. 9 is a flow chart showing a flow of participation request processing in one embodiment. In the participation request processing of FIG. 9, it is assumed that the first viewing user who is viewing the moving image delivered from the server device 20 by the client device 10a requests participation in the moving image. The participation request processing may be performed in parallel with the video distribution processing shown in FIG.

First, in step S16, a participation request requesting participation in the moving image being viewed is received from the client device 10 of the first viewing user. The participation request is transmitted from the client device 10a to the server device 20 in response to the selection of the participation request button 63 displayed on the client device 10a by the first viewing user.

Next, in step S16, it is determined whether or not the participation request from the first viewing user is permitted. This determination is made, for example, by the participation request processing unit 21c described above.

If the participation request is approved, the participation request processing proceeds to step S18. In step S18, the avatar 56a of the first viewing user is arranged at a predetermined position in the virtual space 50. As a result, when the position where the avatar 56a is arranged is included in the drawing area of the virtual camera, the avatar 56a of the first viewing user is included in the delivered moving image. The process for including the avatar 56a in the moving image is performed by, for example, the above-mentioned avatar display unit 21d.

If the participation request is not permitted (rejected), the participation request processing is terminated without displaying the avatar 56a of the first viewing user.

Although the participation request processing has been described by taking the case where the first viewing user makes a participation request as an example, the server device 20 can receive the participation request from a plurality of viewing users at any time during the distribution of the moving image. Therefore, the server device 20 can execute the above-mentioned participation request processing for each of the plurality of participation requests. In this way, the server device 20 can select a plurality of participating users from among the plurality of viewing users who have requested to participate in the moving image.

Next, with reference to FIG. 10, the distribution process of the co-starring moving image in one embodiment will be described. FIG. 10 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. 10, it is assumed that the viewing user who is viewing the video including the character object of the distribution user makes a co-starring request to the distribution user. .. The co-starring moving image distribution processing may be performed in parallel with the moving image distribution processing shown in FIG. 8 and the participation request processing shown in FIG.

First, in step S21, it is determined whether or not a co-starring request is made by a viewing user (participating user) who is permitted to participate in the moving image during distribution of the moving image including the character object of the distribution user. The co-starring request is made, for example, by the first viewing user. If the co-starring request is made by the first viewing user, the process proceeds to step S22.

In step S22, it is determined whether or not to allow co-starring between the first viewing user and the distribution user based on the co-starring request from the first viewing user who applied for co-starring. For example, the co-starring request processing unit 21f determines whether or not to allow the co-starring request. If the co-starring of the first viewing user and the distribution user is permitted, the process proceeds to step S23.

In step S23, a permission notification notifying that the co-starring is permitted is transmitted to the client device 10 of the first viewing user who is permitted to co-star with the distribution user. The permission notification is transmitted, for example, by the co-starring request processing unit 21f. The client device 10 of the first viewing user may display a message 66b indicating that the co-starring is permitted based on the permission notification on the display. The message 66b displayed based on this permission notification allows the first viewing user to know that his / her own avatar is included in the co-starring video, and can prepare for co-starring such as updating the avatar. ..

Subsequently, in step S24, a co-starring moving image including the character object of the distribution user and the avatar of the first viewing user is generated. The generation of the co-starring moving image in step S24 is performed, for example, by the co-starring request processing unit 21f described above.

Next, the process proceeds to step S25. In step S25, the co-starring moving image generated in step S24 is delivered. This co-starring moving image is distributed to the client device 10, other client devices, and the distribution user device via the network 50. As shown in FIG. 7e, the co-starring moving image includes, for example, the character object 56a of the first viewing user and the character object 51 of the distribution user.

Next, the process proceeds to step S26. In step S26, it is determined whether or not the co-starring end condition is satisfied. For example, it is determined that the co-starring end condition is satisfied when a predetermined time or more has elapsed from the start of distribution of the co-starring moving image. If the co-starring end condition is satisfied, the process proceeds to step S27.

In step S27, a process for terminating the distribution of the co-starring moving image is performed. For example, by excluding the character object 51 of the first viewing user who is a guest user from the co-starring video, the co-starring of the first viewing user and the distribution user is terminated. The moving image delivered after the co-starring is finished does not include the character object 51 of the first viewing user. When a plurality of guest users are selected, the co-starring of the guest user other than the first viewing user and the distribution user may be started after the co-starring of the first viewing user and the distribution user is completed. Even if the co-starring with all the guest users is finished, the video may be continuously delivered. 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 61f.

The action and effect produced by the above embodiments will be described. According to the video distribution system 1 in the above embodiment, instead of accepting the co-starring request from all the viewing users who are watching the distributed video, the video is requested to participate in the video. It is configured to accept co-starring requests only from participating users who have been approved for participation. For example, the client device 10 of a viewing user who is not permitted to participate in the video is activated by activating the function for making a co-starring request in the client device 10 of the viewing user (that is, the participating user) who is permitted to participate in the video. By not activating the function for making a co-starring request, the co-starring request can be accepted only from the participating users. As a result, even if the number of viewing users increases, the number of co-starring requests received from the client device 10 can be suppressed.

In the above embodiment, the server device 20 notifies the viewing users other than the participating users who are permitted to participate in the video among the plurality of viewing users who view the video, regarding the selection of the participating users. Is not sent. In one embodiment, the notification regarding the selection of the participating user is transmitted only to the client device 10 of the participating user who is permitted to participate in the moving image among the plurality of viewing users who view the moving image. As a result, in the server device 220, the processing load for generating and transmitting a notification regarding the result of determining whether or not to allow participation can be reduced, and the communication traffic can be reduced.

In one of the above embodiments, the user who requests to participate in the video and is refused is not notified that the user has been refused. In this case, the viewing user who made the participation request knows whether or not his / her participation request is permitted by confirming whether or not his / her character object (avatar) is included in the delivered video. Can be done. In other words, it can be seen that participation was permitted if the delivered video contained one's own avatar, and that participation was not permitted if the delivered video did not contain one's own avatar. As described above, in the above embodiment, by distributing the video including the avatar of the participating user from the server device 20, the participation request is rejected without additionally transmitting the notification other than the video. It is possible to notify all viewing users including the viewing user whether or not the participation request is permitted. That is, in the above embodiment, it is possible to notify the viewing user whose participation request is rejected whether or not the participation request is permitted without transmitting a notification other than the moving image. In addition, by notifying whether or not the participation request is permitted through the video including the avatar of the participating user, it is possible to attract the attention and interest of the viewing user who made the participation request to the delivered video. For videos of popular distribution users, the number of viewing users can be enormous. In this case, the effect of reducing the processing load of the server device 20 is increased by not notifying all the viewing users regarding the selection of the participating users.

In the above embodiment, the server device 20 transmits a command to the client device 10 of the participating user to activate the function for the participating user to make a co-starring request in the client device 10. As a result, it is possible to make a co-starring request in the client device 10 of the participating user among all the viewing users, and it is not possible to make a co-starring request in the client device 10 of the viewing user who is not permitted to participate. Therefore, since the number of users who can make the co-starring request is smaller than that of the entire viewing user, the processing load for processing the co-starring request in the server device 20 can be reduced. When the decision on whether or not to allow co-starring based on the co-starring request is left to the selection by the distribution user, it is possible to reduce the trouble of the decision by the distribution user.

In one of the above embodiments, the co-starring request may include message data indicating a message from a participating user who makes the co-starring request. The co-starring request may include motion data that specifies the movement of the avatar of the participating user who makes the co-starring request. By including the message data and motion data in the co-starring request, the guest user does not have to perform any special operation during the distribution of the co-starring video, based on the data provided before the start of the co-starring in the form of message data or motion data. The movement and voice of the guest user can be controlled.

The embodiment of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist thereof. For example, the moving image to be distributed may be shot and generated in a place other than the studio room R. For example, shooting for generating a video to be delivered may be performed at the home of an actor or a supporter. The client device 10a may have a function of transmitting an image (for example, an image 60e) in which both the avatar 56a and the character object 51 are displayed to another communication device. For example, the first viewing user uses the function of the client device 10a to display an image in which both the avatar 56a and the character object 51 are displayed on the social networking service or the server device 20 in the video service provided by the server device 20. It can be delivered by a social networking service different from the video service provided by.

As described above, at least a part of the functions realized by the computer processor 21 may be realized by a computer processor other than the computer processor 21 of the moving image distribution system 1. At least a part of the functions realized by the computer processor 21 may be realized by the computer processor provided in any of the client devices 10a to 10c, for example. For example, some or all of the functions of the moving image generation unit 21a, the moving image distribution unit 21b, the participation request processing unit 21c, the avatar display unit 21d, the avatar control unit 21e, and the co-starring request processing unit 21f are executed by the client devices 10a to 10c. May be done. Specifically, the moving image generated by any of the client devices 10a to 10c may be transmitted to the server device 20 and distributed from the server device 20 to the client devices 10a to 10c.

When a viewing user who is watching a moving image including the character object 51 of the distribution user on the client device 10a makes a co-starring application with the character object 51 (or its distribution user), the viewing user who made the co-starring application makes a co-starring application. The animation of the avatar 56a may be generated by either the server device 20 or the client device 10a. Further, the generation of the co-starring moving image including the character object 51 and the viewing user's avatar 56a may be performed by either the server device 20 or the client device 10a. The co-starring moving image may be shared and generated by the server device 20, the client device 10a, and other devices. When the co-starring moving image including the character object 51 of the distribution user and the avatar 56a of the viewing user is generated in the client device 10a, the motion data and voice of the distribution user are generated from the server device 20 or the studio unit 30 to the client device 10a. The data may be transmitted to the client device 10a. In the client device 10a, the animation of the character object 51 is generated by applying the received motion data of the distribution user to the model data for the distribution user. The model data of the distribution user may be transmitted from the server device 20 or the studio unit 30 to the client device 10a. When a gift object is included in the co-starring video generated by the client device 10a, data for displaying the gift object is transmitted from the server device 20 or the client device of the viewing user who has performed the gifting to the client device 10a. May be done. As described above, the co-starring moving image 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. Motion data and audio data of the distribution user corresponding to the character object 51 and the viewing user corresponding to the avatar 56a are transmitted to the device for generating the co-starring moving image including the character object 51 and the avatar 56a.
