The material data is, for example, a 3D model, a still image, a moving image, audio data, MIDI data, character data, or the like. FIG. 4 is a diagram showing a structural example of the material library 331. As shown in the figure, the material library 331 stores various material data in association with information (material ID) for specifying the material data. In this embodiment, it is assumed that the character plays rock-paper-scissors with a large number of viewers, and the material for drawing a scene in which the character explains how to proceed with rock-paper-scissors, rules, rewards for the winner, etc. Material for drawing a scene that instructs the viewer when to put out the rock-paper-scissors, material for drawing a scene that shows the result of rock-paper-scissors, material for drawing a scene that declares to continue rock-paper-scissors, rock-paper-scissors It is assumed that the material data such as the material for drawing the scene that declares the end of is registered in the material library 331.

The action storage unit 333 stores information (hereinafter, referred to as action information) related to an operation (action) on the material data. FIG. 5 is a diagram showing an example of action information stored in the action storage unit 333. As shown in the figure, the action information includes an action ID indicating an action, a determination period, a group, a condition, and an action.

The determination period is information indicating a period for determining whether or not the event satisfies the condition. The determination period may be relatively specified, for example, from the present time to 5 minutes before, or may be absolutely specified, such as from 00:00 to 00:10 on December 25th. Further, the action may be specified and the time during which the action is executed (for example, 10 seconds from the start of the action, 10 seconds from the end of the action, etc.) may be set. The length of the determination period can be any time, for example, 1 second, 1 minute, 1 hour, 1 day.

The group indicates the group to which the viewer belongs. When a group is set in the action information, it is determined whether or not the conditions described later are satisfied only for the event information related to the viewers belonging to the set group. For example, when playing rock-paper-scissors between a character in a streamed video and a viewer, the second and subsequent trials may be added on condition that it is a user event from a viewer who belongs to the winner group. it can. It is also possible to omit the group and specify that the viewer belongs to a specific group in the conditions described later.

The condition is for an event, and may be, for example, the presence or absence of an event, or whether or not the aggregated value for the event from a plurality of viewers exceeds the threshold value.

For user event information, for example, whether or not the viewer pressed a predetermined key during playback of the delivered video, whether or not the predetermined area on the video was clicked or tapped, and whether or not the predetermined area on the video was clicked. Alternatively, it can be a condition that the number of viewers tapped exceeds the threshold value. Whether the object displayed in the streamed video was clicked or tapped, and whether the number of viewers who clicked or tapped the object exceeded the threshold, based on the material data used to generate the streamed video. Can also be a condition.

In addition, whether or not a predetermined character (keyword) has been input by the viewer on the viewer terminal 1, for example, whether or not a predetermined keyword is included in the comment posted to the distributed video, the keyword has been input. It is also possible to make a condition such as whether or not the number of viewers exceeds the threshold value. Also, the number of comments or viewers aggregated by region of the viewers who posted comments, for example, the aggregated value of the amount posted by the viewer in response to asking an opinion on the amount in the video (average value, median) Value, maximum value, minimum value, etc.), the number of sorrowful viewers based on the emotions of the viewers judged by parsing the comment, etc. exceeds a predetermined threshold, and comments containing a predetermined keyword Can also be conditioned on the fact that was never posted.

In addition, by performing voice recognition, for example, whether or not a specific word is uttered, whether or not applause, whistling, stepping, etc. are pronounced in the viewer or the viewer's atmosphere, etc. It is also possible to make conditions such as whether or not there is a specific pronunciation, and whether or not the number of viewers who have such a specific pronunciation exceeds the threshold value. In this case, the voice recognition process may be performed by the viewer terminal 1 and the recognition result may be transmitted to the streaming server 2 or the distributor device 3, or the voice data captured from the viewer terminal 1 may be transmitted to the streaming server. It may be transmitted to the distributor device 3 via 2 or directly, and the voice recognition process may be performed in the distributor device 3.

In addition, whether or not the viewer has taken a self-portrait image or the atmosphere of the viewer on the viewer terminal 1, whether or not such an image has been posted to the streaming server 2, and the number of viewers who have posted the image exceeds the threshold value. It can also be a condition of whether or not it is. Also, by image analysis, whether or not an image of a predetermined object (for example, an image of a specific signboard or flyer around the viewer) has been posted, and whether or not the image of the viewer who posted such an image has been posted. It is also possible to make a condition such as whether or not the number of people exceeds the threshold. Furthermore, image analysis recognizes the viewer's posture, line of sight, gesture, etc., and whether or not the viewer has made a predetermined posture, line of sight, or gesture, and the number of viewers who have made a predetermined posture, line of sight, or gesture are threshold values. It can also be a condition such as whether or not it exceeds. In this case, the image analysis process may be performed by the viewer terminal 1 and the analysis result may be transmitted to the streaming server 2 or the distributor device 3, or the image data captured from the viewer terminal 1 may be transmitted to the streaming server. It may be transmitted to the distributor device 3 via 2 or directly, and the image analysis process may be performed in the distributor device 3.

Further, for the system event information, for example, it can be a condition whether or not the number of viewers who are viewing the distributed image exceeds the threshold value. It is also possible to set whether or not a predetermined time has elapsed from the reproduction of the delivered image. In addition, when the weather in the location of the viewer or distributor or in a predetermined area is acquired as system event information, it is a condition whether or not this weather is the predetermined weather (for example, it is sunny, rain). It can be said that it is raining, it is snowing, a wind of a predetermined strength or higher is blowing, a temperature of a predetermined temperature or higher, etc.). Further, when the material data is a 3D model or the like, it can be a condition that the objects collide with each other in the distributed moving image.

The actions are various operations on the material data as described above. Parameters can also be included in the action, and it is possible to set in detail what kind of operation is specifically performed on the material data. Further, in the present embodiment, the action can include not only an operation on the material data but also a process of executing or stopping another action, waiting for the execution of the other action to be completed, and the like. Actions can also be stored, for example, as a program written in a scripting language.

The event storage unit 334 stores various events that have occurred. FIG. 6 is a diagram showing a configuration example of the event storage unit 334. As described above, the event storage unit 334 stores the user event information and the system event information. Hereinafter, the user event information and the system event information are collectively referred to as event information. The user event information includes an event ID indicating an event, a viewer ID indicating a viewer related to the event, a date and time when the event occurred, and the content of the event. In addition, the system event information includes the event ID, the date and time when the event occurred, and the content of the event. The content of the event differs depending on the event. For example, in the case of user event information, when a viewer posts a comment on the delivered video, the posted comment can be set as the event content. Further, when the viewer terminal 1 analyzes the image of the viewer and obtains the viewer's line of sight or gesture, information indicating the line of sight or gesture can be set as the content of the event. In the case of system event information, the number of viewers, weather, time, etc. can be set as the content of the event.

The group condition storage unit 335 stores conditions for grouping viewers (hereinafter, referred to as group condition information). FIG. 7 is a diagram showing a configuration example of the group condition storage unit 335. The group condition information includes the determination period, the condition and the group. The determination period is information indicating a period for grouping. The determination period may be, for example, a start date and time and an end date and time, as in the determination period of the action information described above, or the time when the action is specified and the action is executed (for example, 10 seconds from the start of the action, the action). It may be 10 seconds until the end). The length of the determination period can be any time, for example, 1 second, 1 minute, 1 hour, 1 day. The condition is a condition related to a specific viewer, and can be a condition related to the latest user event, a past user event, a group to which the viewer belongs, and the like. For example, for the very first rock-paper-scissors game that started, the conditions for the rock-paper-scissors hand issued by the viewer (for example, the viewer's hand is par) are set, and for the second and subsequent rock-paper-scissors, viewing. It can be set that the person belongs to the winner group and the hand that is put out is a predetermined hand (goo, choki, or par). A plurality of conditions may be set in the group condition information. The group is a group to which viewers satisfying the above conditions belong. For example, in the case of group condition information in which the condition specifies that the player belongs to the winner group and has issued a goo, and the winner group is specified in the group, the player wins up to the previous round (may include Aiko). .) Indicates that the viewers who have continued and who have issued a goo within the judgment period will belong to the winner group. In this embodiment, it is assumed that group condition information is set for all patterns that the viewer can take. For example, it is assumed that the group condition information that specifies the condition of default (viewer who did not match other conditions) is included.

The group storage unit 336 manages the group to which the viewer related to the distributed video belongs. FIG. 8 is a diagram showing a configuration example of the group storage unit 336. The group storage unit 336 stores group information, and the group information includes a viewer ID indicating a viewer and a group to which the viewer belongs.

The video distribution unit 311 distributes the video. The video distribution unit 311 synthesizes (encodes as necessary) the output from the action (a plurality of actions may be executed) executed by the action processing unit 313 described later, and generates the distribution video. can do. Further, the video distribution unit 311 can distribute the video to the viewer terminal 1 by transmitting the generated distribution video to the streaming server 2.

The event acquisition unit 312 acquires an event and registers the content of the acquired event in the event storage unit 334 as event information. It is assumed that the user can set what kind of event the event acquisition unit 312 acquires. The setting information indicating what kind of event is to be acquired can be stored in, for example, a memory 302 or a storage device 303.

The event acquisition unit 312 can register, for example, an event such as a key, a tap, or a click input by the viewer as user event information. For example, when the distribution video is viewed on the Web browser on the viewer terminal 1, a script is set so as to send the click event generated on the Web browser to the streaming server 2 or the distributor device 3. The event acquisition unit 312 can acquire the click event via the streaming server 2 or directly from the viewer terminal 1.

Further, for example, when the streaming server 2 provides an API for acquiring the posted comment, the event acquisition unit 312 acquires the comment posted by the viewer by calling the API. can do. In addition, the event acquisition unit 312 may parse the comment and register that a predetermined keyword is included as user event information.

Further, the event acquisition unit 312 can receive, for example, the voice data captured from the viewer terminal 1, analyze the received voice data, and register that a specific pronunciation has occurred as user event information. The audio analysis process is performed on the viewer terminal 1, and the event acquisition unit 312 receives the analysis result directly from the viewer terminal 1 or via the streaming server 2 and registers it as user event information. You may. In addition, the event acquisition unit 312 can also receive an image of the viewer taken from the viewer terminal 1 and analyze the received image to acquire the viewer's posture, line of sight, gesture, and the like. Alternatively, the viewer terminal 1 may analyze the image and receive the result. The event acquisition unit 312 may periodically count the number of viewers who are watching and register it in the system event information. The image analysis process is performed on the viewer terminal 1, and the event acquisition unit 312 receives the analysis result directly from the viewer terminal 1 or via the streaming server 2 and registers it as user event information. You may.

Further, in the case of rock-paper-scissors assumed in the present embodiment, the event acquisition unit 312 can register, for example, that the viewer has made a hand of rock-paper-scissors as user event information. The fact that the rock-paper-scissors hand is put out is that, for example, the viewer terminal 1 can display a button for inputting the rock-paper-scissors hand (goo, choki, par) on the Web browser and make the viewer click. .. In addition, a video showing a rock-paper-scissors hand is included in the distribution video, an area corresponding to each hand is set, and the position where the viewer terminal 1 is clicked in the distribution video can be determined via the streaming server 2 or. It is directly transmitted to the distributor device 3, and the event acquisition unit 312 can determine the hand of the rock-paper-scissors that the viewer put out depending on whether or not the clicked position enters the area corresponding to each of the above hands. Further, this determination may be performed on the viewer terminal 1 or the streaming server 2. Further, the event acquisition unit 312 can identify the rock-paper-scissors hand issued by the viewer by, for example, extracting the word indicating the rock-paper-scissors hand described in the comment posted by the viewer.

Further, the event acquisition unit 312 can, for example, acquire a timeout event from the clock and register as system event information that a predetermined time has elapsed from the start of reproduction of the distributed image. The event acquisition unit 312 can also register that the predetermined time has come (for example, the date has changed, the time has reached 3:00 pm, etc.) as system event information.

In addition, the event acquisition unit 312 acquires weather information from, for example, a server of a weather company, and obtains weather elements in a specific area (for example, the location of each viewer or the location of a distributor, or a preset area). It can also be registered as system event information.

Further, the event acquisition unit 312 can determine that an object has collided in the distributed moving image and register it as system event information, for example, when the material data is a 3D model or the like.

The action processing unit 313 executes an action on the material data. The action processing unit 313 accepts the designation of the action to be executed first, and executes the accepted action. Since the action may include the activation of another action, in this case, the action processing unit 313 can continue to activate the actions in sequence. It is also possible to branch an action into a plurality of actions and execute them in parallel.

The action processing unit 313 also executes an action according to the event. The action processing unit 313 reads the event information corresponding to the period from the event storage unit 334 for each of the action information stored in the action storage unit 333, aggregates the information, determines whether or not the condition is satisfied, and sets the condition. If it is satisfied, the action set in the action information is executed. This makes it possible to dynamically change the development of the moving image according to the event.

The action processing unit 313 further considers a group of viewers. That is, when a group is set in the action information, the action processing unit 313 executes the action according to only the event information corresponding to the viewer belonging to the set group. For example, in the case of rock-paper-scissors, the action should be executed only for the event from the viewer who belongs to the winner group. This makes it possible to proceed with the game correctly without considering the event from the loser in the progress of rock-paper-scissors.

The group setting unit 314 divides the viewers into groups. In the present embodiment, the group setting unit 314 groups the users each time the action processing unit 313 executes the action, but the group setting unit 314 may perform the grouping at an arbitrary timing. For example, when the event acquisition unit 312 acquires a preset event (for example, when there is a reaction from the viewer such as posting a comment), or when a predetermined time elapses, grouping is performed. It can be carried out. The group setting unit 314 searches for each of the viewers the group condition information registered in the group condition information storage unit 335 that satisfies the condition, and the group set in the searched group condition information. It is decided that the viewer belongs to. The group setting unit 314 creates group information for associating the determined viewer with the group and registers it in the group storage unit 336. If the group information corresponding to the viewer is already registered in the group storage unit 336, the group information shall be updated. In the present embodiment, the group condition information includes the conditions for the rock-paper-scissors hand (and for the second and subsequent rock-paper-scissors trials, the group to which the viewer belongs is the "winner group") and the conditions. It is assumed that the satisfied viewers are set as the "winner group". In addition, it is assumed that group condition information for setting other viewers as a "loser group" is also set. Therefore, the group setting unit 314 can repeat the trial of rock-paper-scissors and reduce the number of viewers belonging to the winner group.

The total output unit 315 can output various totals. For example, the total output unit 315 counts the number of viewers from the user event information registered in the past, or totals the number of viewers who posted a comment including the word for each specific word. can do. In addition, the total output unit 315 can total the number of viewers for each group from, for example, the group effective unit 336. The total output unit 315 can output the total number. The output from the total output unit 315 may be transmitted to the viewer terminal 1 separately from the distributed image and displayed on the viewer terminal 1, or may be superimposed and displayed on the distributed image.

The reward processing unit 316 performs processing for rewarding the viewer according to the group. The reward processing unit 316 may, for example, reward only the viewers who belong to a specific group, or may give different rewards for each group. Regarding the process of giving rewards by the reward processing unit 316, it is explained here as processing related to general rewards such as adding points, transferring funds of virtual currency, and giving items. Is omitted. In the present embodiment, the reward processing unit 316 performs a process of giving a reward to each of the winners of rock-paper-scissors, that is, the viewers belonging to the winner group.

FIG. 9 is a diagram illustrating a flow of processing executed by the moving image distribution system of the present embodiment.

The action processing unit 313 accepts the designation of the action to be executed first (S421), and executes the designated action (S422). The video and audio output as a result of executing the action are synthesized and transmitted as moving image data to the streaming server 2 by the moving image distribution unit 311.

The event acquisition unit 312 periodically acquires an event (S423). For example, the event acquisition unit 312 can acquire the comment posted on the distributed video by calling the API provided by the streaming server 2. Further, the event acquisition unit 312 can acquire that a predetermined time has elapsed by using the timer function.

For each action information stored in the action storage unit 333, the action processing unit 313 corresponds to the group when the group is set in the action information (S424: YES), and the event of the date and time when the determination period is entered. The information is read from the event storage unit 334 (S425), and if no group is set in the action information (S424: NO), all the event information on the date and time when the determination period is entered is read from the event storage unit 334 (S426).

The action processing unit 313 determines whether or not the event content of the read event information satisfies the condition of the action information (S427). When the action information includes information other than event information and group information and includes conditions for information managed by the distributor device 3 or information that can be acquired by accessing another information processing device. In order to obtain this information, it may be determined whether or not the condition is satisfied. When the event satisfies the condition (S428: YES), the action processing unit 313 executes the action included in the action information (S429). Here, the action processing unit 313 may stop the previously executed action, or may execute a new action in parallel with the previously executed action, and this behavior may be performed. It may be possible to specify it in a new action. The group setting unit 314 divides the viewers into groups (S430). FIG. 10 is a diagram illustrating a flow of viewer grouping processing according to the present embodiment. The group setting unit 314 performs the following processing for each viewer related to the event information. The group setting unit 314 reads the group condition information from the group condition storage unit 335 (S441), and for each read group condition information, the event information corresponding to the viewer and the date and time when the determination period is entered is stored in the event storage unit.
