The second list display data includes, for example, an object display button into which an object display instruction can be input by the viewer for a topic included in the list. The object display instruction is an instruction to display an object for a topic selected by the viewer. The topic selected by the viewer is a topic for which an object is to be displayed. The topic for which an object is to be displayed is also called an object display target topic. The object display instruction may include topic identification information for identifying the object display target topic, and viewer identification information for identifying the viewer who selected the object display target topic. The object display target topic is an example of object display target content. The object display button may be, for example, an area in which topics included in the list are displayed. The object display button is an example of a second element.

[0064] The object is, for example, an object that indicates an action from a viewer toward a distributor. The action is an example of communication from a viewer toward a distributor. For example, a viewer performs an action toward a distributor. A distributor receives an action from a viewer. A viewer and a distributor can communicate through actions. A large amount of actions indicates active communication. Active communication indicates excitement in video distribution. Viewers and distributors can liven up video distribution by actively communicating with each other. The action includes, for example, a viewer's expression of intent. The expression of intent includes an expression of intent regarding a specific topic. The expression of intent includes an expression of intent indicating an interest in a topic, a desire to share the topic, a desire to talk about the topic, and the like. The object is, for example, an object that visualizes an "interesting action." The "interesting action" is, for example, an action that indicates the viewer's interest. The "interesting action" is a means of communication for the viewer. The "interesting action" indicates an expression of intent indicating an action toward a topic, or a reaction to a topic.

[0065] The object may be an object showing a viewer's reaction to the distributor. The reaction may be, for example, an answer to a question from the distributor, a questionnaire, or the like. The action may include an action from a viewer toward other viewers. The reaction may include a reaction from a viewer toward other viewers.

[0066] The object is a symbol, a mark, an icon, or the like. The object may be of any color, shape, or size. The object is, for example, a star-shaped mark. The object is not limited to the above, and may be anything that visually indicates the amount of action of the viewer, the excitement, or the like. For example, the object indicates the amount of action of the viewer, or the number of actions. Specifically, the object indicates the number of object display instructions input by the viewer, or the number of times. For example, when an object display instruction is input by the viewer for "topic A", an object is displayed for "topic A". The object may be displayed every time an object display instruction is input by the viewer. For example, when an object display instruction is input once by the viewer for "topic A", one object is displayed for "topic A". For example, the more times the viewer inputs the object display instruction, the more the number of objects displayed may be. The number of objects may be the same as the number of object display instructions, or may be different.

[0067] Displaying an object is an example of performing an action. Inputting an instruction to display an object is an example of performing an action.

[0068] The object may be an indicator of a topic that a viewer is interested in. For example, a broadcaster may recognize a topic that multiple viewers are interested in based on the object. A broadcaster may share a topic that multiple viewers are interested in based on the object.

[0069] The information content processing unit 112 transmits second list display data including a list of information contents to the viewer terminal 3 via the network. The viewer selects a desired topic from the topics included in the list. The viewer can display an object for the selected topic by operating an object display button. Based on the viewer's operation of the object display button, the viewer terminal 3 outputs an object display instruction to the video distribution device 1 via the network to display an object for the object display target topic.

[0070] The information content processing unit 112 receives an object display instruction from the viewer terminal 3 via the network. The information content processing unit 112 may store information related to the object in the storage unit 13. The information related to the object includes, for example, topic identification information, viewer identification information, time information, etc. The time information is, for example, information indicating the time when the object display instruction was obtained from the viewer terminal 3.

[0071] The information content processing unit 112 generates second selected content display data for displaying at least a part of the selected topic based on receiving a topic selection instruction from the distributor terminal 2 via the network. The second selected content display data is an example of second information content data. The second selected content display data includes data for displaying the same selected topic as the first selected content. The second selected content display data may include information regarding the source of the selected topic.

[0072] The second selected content display data includes, for example, a full text display button through which an instruction to display the full text of the selected topic can be input. The full text display button is an example of a second element. The second selected content display data includes, for example, an access button through which an instruction to access a collection source page of the selected topic can be input by the viewer. The access button is an example of a second element.

[0073] The information content processing unit 112 transmits the generated second selected content display data to the viewer terminal 3 based on a topic selection instruction from the distributor terminal 2. For example, the information content processing unit 112 switches between the display of the list and the selected topic in the viewer terminal 3 based on a topic selection instruction from the distributor. The information content processing unit 112 switches between the display of the list and the selected topic in the viewer terminal 3 based on an instruction from the distributor to display the list, for example.

[0074] The information content processing unit 112 performs object processing. The information content processing unit 112 generates object display data based on receiving an object display instruction from the viewer terminal 3 via the network. The object display data is data for displaying an object for an object display target topic. The information content processing unit 112 may generate object display data every time an object display instruction is received.

[0075] The information content processing unit 112 outputs object display data based on an object display instruction by a viewer via the object display button. The information content processing unit 112 transmits the object display data to the distributor terminal 2 via the network. The information content processing unit 112 transmits the object display data to the viewer terminal 3 via the network. The information content processing unit 112 may transmit the object display data to another viewer terminal 3 via the network. The other viewer terminal 3 is a viewer terminal of a viewer who is viewing the same video content as the video content that the viewer terminal 3 is viewing.

[0076] The information content processing unit 112 may perform a process of controlling the display of objects. The information content processing unit 112 may limit the number of objects displayed within a predetermined time. For example, the information content processing unit 112 may limit the number of objects that can be displayed within a predetermined time to a predetermined number. The information content processing unit 112 may limit the number of objects that can be displayed within a predetermined time for each selected topic to a predetermined number. When the information content processing unit 112 acquires a number of object display instructions that exceed a predetermined number within a predetermined time, the information content processing unit 112 may display a thinned-out number of objects. When the information content processing unit 112 acquires a number of object display instructions that exceed a predetermined number, the information content processing unit 112 may change the display mode of the object when the number of object display instructions exceeds a predetermined number. The display mode includes at least the shape, color, size, and display position. For example, the information content processing unit 112 may change the shape of the object from a star shape to a circle shape when the number of object display instructions exceeds five times. The information content processing unit 112 may change the color of the object from yellow to red when the number of object display instructions exceeds five times. When the number of object display instructions exceeds five, the information content processing unit 112 may change the size of the object from the reference size to a larger size object. The reference size indicates, for example, the size of the object displayed when the number of object display instructions is five or less. The information content processing unit 112 may change the display mode of the object based on the order of time when the viewer inputs the object display instructions. For example, the information content processing unit 112 may change the color of the object depending on the time the object is displayed. The information content processing unit 112 may change the display mode of the object based on the user rank of the viewer of the viewer terminal 3 that transmitted the object display instruction.

[0115] The list display area includes an object Ob1. The object may be displayed for each of the topic boxes included in the list display area. In the example of FIG. 7, the area A6 includes a plurality of objects. The area A6 is an area for displaying objects given by a viewer to the topic box T1. The area A6 indicates that an object display instruction has been input by the viewer to the topic box T1. The area A6 indicates, for example, the amount of "interesting actions" input for the topic displayed in the topic box T1. The number of objects displayed in the area A6 is a number according to the number of times an object display instruction has been input by the viewer. The number of objects displayed in the area A6 may be the same number as the number of times an object display instruction has been input by the viewer, or may be a number that relatively represents the number of times an object display instruction has been input. In the example of FIG. 7, the number of objects for the topic box T1 is greater than the number of objects for the topic box T2. In FIG. 7, it is indicated that the topic displayed in the topic box T1 has been subjected to "interesting actions" by more viewers than the topic displayed in the topic box T2. The list display image Im5 is also displayed on the viewer terminal 3 in the same manner.

[0116] According to this example, the video distribution device 1 displays an object in association with the object target topic based on receiving an object display instruction from the viewer terminal 3. The video distribution device 1 can visualize actions from the viewer. The broadcaster can recognize topics in which the viewer is interested by the object being displayed in association with the object target topic. The broadcaster can select a topic as a selected topic based on the viewer's action. The viewer can inform the broadcaster of a topic in which the viewer is interested. Therefore, the video distribution device 1 can stimulate communication between the broadcaster and the viewer based on the information content. In this way, the video distribution device 1 can support communication between the broadcaster and the viewer during the broadcast of video content. (Example of operation) The operation of the video distribution system S will be described. The process procedure described below is merely an example, and each process may be changed as much as possible. Each process may be omitted or replaced depending on the embodiment, and new processes may be added.

[0117] In the following description mainly focusing on video distribution device 1, video distribution device 1 may be read as control unit 11.

In the following description mainly focusing on viewer terminal 3, viewer terminal 3 may be read as a control unit or processing circuit of viewer terminal 3. In the following description, it is assumed that video content is distributed to a viewer terminal 3, and information content is displayed during the distribution of the video content. Note that the video content may be distributed to a distributor terminal 2. Note that multiple viewer terminals 3 refer to viewer terminals 3 that are viewing the same video content. In the following description, an example will be described in which live broadcast content is distributed by a distributor.

[0118] The distributor terminal 2 transmits video content to the video distribution device 1. The control unit 11 of the moving image distribution device 1 acquires the moving image content from the distributor terminal 2 via the network. This process may be performed by a moving image content acquisition unit 110 realized by the control unit 11. The control unit 11 stores the moving image content in the storage unit 13.

[0119] The control unit 11 distributes the video content to the viewer terminal 3 of the viewer via the network (step S11). Step S11 may be a process performed by the video content distribution unit 111 realized by the control unit 11. In step S11, for example, the control unit 11 receives a video content distribution request from the viewer terminal 3. The control unit 11 acquires video content data stored in the storage unit 13 based on content identification information included in the video content distribution request. The control unit 11 distributes the video content data to the viewer terminal 3 as the distribution destination.

[0120] The viewer terminal 3 receives the video content data from the video distribution device 1 via the network. The viewer terminal 3 displays the video content (step S21). In step S21, for example, the viewer terminal 3 displays the video content on a display device based on the video content data.

[0121] A distributor of the distributor terminal 2 inputs an information content display instruction to display information content while distributing video content. The distributor terminal 2 outputs the information content display instruction to the video distribution device 1 via the network (step S1). In step S1, for example, the distributor terminal 2 acquires the information content display instruction based on the distributor's operation of an information content display button or the like. The distributor terminal 2 outputs the information content display instruction to the video distribution device 1 based on the distributor's operation.

[0122] The control unit 11 of the video distribution device 1 receives an information content display instruction from the distributor terminal 2 via the network. Based on the information content display instruction received, the control unit 11 generates content menu display data. This process may be performed by the information content processing unit 112 realized by the control unit 11. Based on the information content data, the control unit 11 generates first content menu display data and second content menu display data.

[0123] The control unit 11 outputs the content menu display data (step S12). Step S12 may be a process performed by the information content processing unit 112 realized by the control unit 11. In step S12, for example, the control unit 11 outputs the first content menu display data to the distributor terminal 2 via the network. The control unit 11 outputs the second content menu display data to the viewer terminal 3 via the network.

[0124] The viewer terminal 3 receives the second content menu display data via the network from the moving image distribution device 1. The viewer terminal 3 displays the content menu on the display device based on the second content menu display data (step S22).

[0125] The distributor terminal 2 receives, via the network, the first content menu display data from the moving image distribution device 1. The distributor terminal 2 displays the content menu on the display device based on the first content menu display data (step S2).

[0126] The distributor terminal 2 acquires a genre selection instruction based on an input from the distributor using a genre selection button or the like. The distributor terminal 2 outputs the genre selection instruction to the video distribution device 1 via the network (step S3). In step S3, for example, the distributor terminal 2 may output genre identification information capable of identifying the genre selected by the distributor to the video distribution device 1. The distributor terminal 2 may output distributor identification information capable of identifying the distributor to the video distribution device 1.

[0127] The control unit 11 of the video distribution device 1 receives a genre selection instruction from the distributor terminal 2 via the network. The control unit 11 generates list display data based on the received genre selection instruction. This process may be performed by the information content processing unit 112 realized by the control unit 11. The control unit 11 generates first list display data and second list display data based on the information content data, for example. The control unit 11 may create list display data in which the information contents are arranged in a predetermined order.

[0128] The control unit 11 outputs the list display data (step S13). Step S13 may be a process performed by the information content processing unit 112 realized by the control unit 11. In step S13, for example, the control unit 11 outputs the first list display data to the distributor terminal 2 via the network. The control unit 11 outputs the second list display data to the viewer terminal 3 via the network.

[0129] The viewer terminal 3 receives the second list display data via the network from the moving image distribution device 1. The viewer terminal 3 displays the list on the display device based on the second list display data (step S23).

[0130] The distributor terminal 2 receives, via the network, the first list display data from the moving image distribution device 1. The distributor terminal 2 displays the list on the display device based on the first list display data (step S4).

[0131] The control unit 11 of the moving image distribution device 1 performs object processing, which will be described later (step S14). Step S14 may be processing performed by the information content processing unit 112 realized by the control unit 11.

[0132] The distributor terminal 2 acquires a topic selection instruction based on an input from the distributor using a topic selection button or the like. The distributor terminal 2 outputs the topic selection instruction to the video distribution device 1 via the network (step S5). In step S5, for example, the distributor terminal 2 may output topic identification information capable of identifying the selected topic selected by the distributor to the video distribution device 1. The distributor terminal 2 may output distributor identification information capable of identifying the distributor who selected the selected topic to the video distribution device 1.

[0133] The control unit 11 of the video distribution device 1 receives a topic selection instruction from the distributor terminal 2 via the network. Based on the received topic selection instruction, the control unit 11 generates selected content display data. This process may be performed by the information content processing unit 112 realized by the control unit 11. The control unit 11 generates, for example, first selected content display data and second selected content display data.

[0134] The control unit 11 outputs the selected content display data (step S15). Step S15 may be a process performed by the information content processing unit 112 realized by the control unit 11. In step S15, for example, the control unit 11 outputs the first selected content display data to the distributor terminal 2 via the network. The control unit 11 outputs the second selected content display data to the viewer terminal 3 via the network.

[0135] The viewer terminal 3 receives the second selected content display data via the network from the moving image distribution device 1. The viewer terminal 3 displays the selected content on the display device based on the second selected content display data (step S24).

[0136] The distributor terminal 2 receives, via the network, the first selected content display data from the moving image distribution device 1. The distributor terminal 2 displays the selected content on the display device based on the first selected content display data (step S6).

[0137] The broadcaster terminal 2 determines whether or not a switching instruction has been issued by the broadcaster (step S7). In step S7, for example, the broadcaster terminal 2 determines whether or not a switching instruction has been issued based on whether or not a switching instruction has been acquired by the broadcaster through input of a back button or the like. If the broadcaster terminal 2 acquires a switching instruction, it determines that a switching instruction has been issued by the broadcaster. If the broadcaster terminal 2 does not acquire a switching instruction, it determines that a switching instruction has not been issued by the broadcaster. If a switching instruction has not been issued (step S7: NO), the process performed by the broadcaster terminal 2 repeats step S7. If a switching instruction has been issued (step S7: YES), the process performed by the broadcaster terminal 2 transitions from step S7 to step S8.

[0138] The distributor terminal 2 outputs a switching instruction to the moving image distribution device 1 via the network (step S8).

[0139] The control unit 11 of the video distribution device 1 receives a switching instruction from the distributor terminal 2 via the network. The control unit 11 generates list display data based on the reception of the switching instruction. This process may be a process by the information content processing unit 112 realized by the control unit 11. The control unit 11 generates, for example, first list display data and second list display data. For example, the control unit 11 may generate the list display data so that topic boxes corresponding to topics previously selected by the distributor are displayed in a different display mode from other topic boxes corresponding to topics not selected by the distributor. The display mode includes character color, size, font, background color, brightness or luminance, background pattern, frame color, blinking display, etc.

[0140] The control unit 11 outputs the list display data (step S16). Step S16 may be a process performed by the information content processing unit 112 realized by the control unit 11. In step S16, for example, the control unit 11 outputs the first list display data to the distributor terminal 2 via the network. The control unit 11 outputs the second list display data to the viewer terminal 3 via the network.

[0141] The viewer terminal 3 receives the second list display data via the network from the moving image distribution device 1. The viewer terminal 3 displays the list on the display device based on the second list display data (step S25).

[0142] The distributor terminal 2 receives the first list display data via the network from the moving image distribution device 1. The distributor terminal 2 displays the list on the display device based on the first list display data (step S9).

[0143] The distributor terminal 2 judges whether or not an end instruction has been given by the distributor (step S10). In step S10, for example, the distributor terminal 2 judges whether or not an end instruction has been given based on whether or not an end instruction has been received by the distributor through input of an end button or the like. If the distributor terminal 2 has received an end instruction, it judges that an end instruction has been given by the distributor. If the distributor terminal 2 has not received an end instruction, it judges that an end instruction has not been given by the distributor. If an end instruction has not been given (step S10: NO), the process performed by the distributor terminal 2 repeats step S10. If an end instruction has been given (step S10: YES), the distributor terminal 2 hides the information content. For example, the distributor can input an end instruction even when a list is displayed or when a selected content is displayed. The distributor terminal 2 hides the information content based on the fact that an end instruction has been received. The distributor terminal 2 outputs an end instruction to the video distribution device 1 via the network.

[0144] The control unit 11 of the video distribution device 1 receives the end instruction from the distributor terminal 2 via the network. Based on the reception of the end instruction, the control unit 11 outputs a non-display instruction to the viewer terminal 3 via the network to hide the information content (step S17).

[0145] The viewer terminal 3 receives the non-display instruction via the network from the moving image distribution device 1. The viewer terminal 3 hides the information content based on the non-display instruction.

[0146] According to this example, the video distribution system S can display information content on the distributor terminal 2 and the viewer terminal 3 based on an instruction obtained from the distributor terminal 2. Therefore, the video distribution system S can provide the distributor with topics to share with the viewer. This allows the video distribution system S to support communication between the distributor and the viewer. Furthermore, the video distribution system S can display a selected topic selected by the distributor on the viewer terminal 3. Therefore, the video distribution system S can support communication between the distributor and the viewer based on the topic selected by the distributor.

[0147] 9 is a sequence diagram illustrating a procedure of information processing related to object display by the video distribution system S of the embodiment. The information processing illustrated in FIG. 9 is the processing of step S14 in the sequence diagram illustrated in FIG.

[0148] In the following process, it is assumed that a viewer using the viewer terminal 3 is viewing video content distributed by a distributor using the distributor terminal 2. It is assumed that the viewer is viewing information content that includes the same content as the information content displayed on the distributor terminal 2.

[0149] It is assumed that the viewer terminal 3 displays on a display device a list based on the second list display data generated by the video distribution device 1. The viewer performs an action on multiple topics included in the list. The viewer selects a target topic for object display from the multiple topics included in the list.

[0150] The viewer terminal 3 acquires an object display instruction based on an input by a viewer of an object display button or the like for a topic for which an object is to be displayed. The viewer terminal 3 outputs the object display instruction to the video distribution device 1 via a network (step S121). In step S121, for example, the viewer terminal 3 may output topic identification information capable of identifying the topic for which an object is to be displayed selected by the viewer to the video distribution device 1. The distributor terminal 2 may output viewer identification information capable of identifying the viewer who selected the topic for which an object is to be displayed to the video distribution device 1.

[0151] The control unit 11 of the video distribution device 1 receives an object display instruction from the viewer terminal 3 via the network. Based on the reception of the object display instruction, the control unit 11 generates object display data. This process may be a process by the information content processing unit 112 realized by the control unit 11. The control unit 11 generates, for example, first object display data and second object display data. The first object display data and the second object display data may be the same data or may be different data.

[0152] The control unit 11 outputs the object display data (step S111). Step S111 may be a process performed by the information content processing unit 112 realized by the control unit 11. In step S111, for example, the control unit 11 outputs the first object display data to the distributor terminal 2 via the network. The control unit 11 outputs the second object display to the viewer terminal 3 via the network.

[0153] The distributor terminal 2 receives the first object display data from the video distribution device 1 via the network. The distributor terminal 2 displays the objects on the display device based on the first object display data (step S101). The distributor terminal 2 displays the objects on the display device, for example, by synthesizing or superimposing the objects in a list.

[0154] The distributor terminal 2 determines whether a predetermined time has passed since the object was displayed (step S102). In step S102, for example, the distributor terminal 2 may determine whether a predetermined time has passed since the distributor terminal 2 received the first object display data from the video distribution device 1.

[0155] If a predetermined time has passed since the broadcaster terminal 2 received the object display data, the broadcaster terminal 2 determines that a predetermined time has passed since the broadcaster terminal 2 displayed the object. If a predetermined time has not passed since the broadcaster terminal 2 received the object display data, the broadcaster terminal 2 determines that a predetermined time has not passed since the broadcaster terminal 2 displayed the object. If a predetermined time has not passed since the broadcaster terminal 2 displayed the object (step S102: NO), the broadcaster terminal 2 repeats step S1102. If a predetermined time has passed since the broadcaster terminal 2 displayed the object (step S102: YES), the broadcaster terminal 2 transitions from step S102 to step S103.

[0156] The distributor terminal 2 hides the object when a predetermined time has elapsed since the object was displayed (step S103). In the distributor terminal 2, the object is hidden when a predetermined time has elapsed. The distributor terminal 2 may hide the object based on an object hide instruction output by the video distribution device 1. For example, the video distribution device 1 may output an object hide instruction to the distributor terminal 2 when a predetermined time has elapsed since receiving an object display instruction from the viewer terminal 3. The distributor terminal 2 may change the display mode of the object based on the time order in which the viewer inputs the object display instructions. The distributor terminal 2 may change the color of the object depending on the time the object is displayed.

[0157] The viewer terminal 3 receives the second object display data from the video distribution device 1 via the network. The viewer terminal 3 displays the objects on the display device based on the second object display data (step S122). The viewer terminal 3 displays the objects on the display device, for example, by synthesizing or superimposing the objects in a list.

[0158] The viewer terminal 3 determines whether or not a predetermined time has elapsed since the object was displayed (step S123). In step S123, for example, the viewer terminal 3 may determine whether or not a predetermined time has elapsed since the viewer terminal 3 received the second object display data from the video distribution device 1.

[0159] If a predetermined time has passed since the viewer terminal 3 received the object display data, the viewer terminal 3 determines that the predetermined time has passed since the object was displayed. If a predetermined time has not passed since the viewer terminal 3 received the object display data, the viewer terminal 3 determines that the predetermined time has not passed since the object was displayed. If the predetermined time has not passed since the object was displayed (step S123: NO), the process performed by the viewer terminal 3 repeats step S123. If a predetermined time has passed since the object was displayed (step S123: YES), the process performed by the viewer terminal 3 transitions from step S123 to step S124.

[0160] The viewer terminal 3 hides the object based on the elapse of a predetermined time since the object was displayed (step S124). In the viewer terminal 3, the object is hidden based on the elapse of a predetermined time. The viewer terminal 3 may hide the object based on an object hide instruction output by the video distribution device 1. For example, the video distribution device 1 may output an object hide instruction to the viewer terminal 3 based on the elapse of a predetermined time since the video distribution device 1 received an object display instruction from the viewer terminal 3. The video distribution device 1 may receive an object hide instruction from the distributor terminal 2. The distributor terminal 2 may output an object hide instruction to the video distribution device 1 based on the elapse of a predetermined time since the object was displayed. The video distribution device 1 may output an object hide instruction to the viewer terminal 3 based on the reception of the object hide instruction from the distributor terminal 2. The viewer terminal 3 may change the display mode of the object based on the order of time when the viewer inputs the object display instructions. The viewer terminal 3 may change the color of the object depending on the time the object is displayed.

[0161] According to this example, the video distribution system S can display the object on the distributor terminal 2 and the viewer terminal 3 based on an instruction acquired from the viewer terminal 3. The viewer can inform the distributor of a topic in which he or she is interested by displaying the object. Therefore, the video distribution system S can enable the distributor to visually recognize a topic in which the viewer is interested. This allows the video distribution system S to support communication between the distributor and the viewer. Furthermore, the distributor can select a selection topic while communicating with the viewer based on the object. For example, the distributor can react to the viewer's action by selecting a topic in which the object is displayed. Therefore, the video distribution system S can activate communication between the distributor and the viewer based on the object.

[0162] The viewer terminal 3 may be able to input an object display instruction multiple times for the same topic. For example, the video distribution device 1 may output data for displaying an object display button to the viewer terminal 3 in a manner in which an object display instruction can be input multiple times for the same topic. According to this example, the viewer can take an action multiple times for the same topic. By taking an action multiple times, the viewer can convey the viewer's interest or level of interest to the distributor. For example, the viewer terminal 3 can output an object display instruction to the video distribution device 1 according to the number of times the action has been taken. The video distribution device 1 can cause the distributor terminal 2 to display an object according to the number of times the action has been taken. The distributor can recognize the viewer's interest or level of interest based on the number of objects displayed, etc.

[0163] The viewer terminal 3 may limit the number of object display instructions that can be input by a viewer within a predetermined time for the same topic. For example, the video distribution device 1 may output data for displaying an object display button to the viewer terminal 3 in a manner that limits the number of objects that can be input within a predetermined time for the same topic. The video distribution device 1 may output data for displaying an object display button to the viewer terminal 3 in a manner that allows an object display instruction to be input once every predetermined time for the same topic. According to this example, the number of times that a viewer can perform an action for the same topic is limited. Therefore, the video distribution device 1 can prevent the object display button from being repeatedly pressed by the same viewer for the same topic.

[0164] The viewer terminal 3 may limit the number of object display instructions that can be input within a predetermined time, not limited to the same topic. For example, the video distribution device 1 may output data for displaying an object display button to the viewer terminal 3 in a manner that limits the number of objects that can be input within a predetermined time for all topics. The video distribution device 1 may output data for displaying an object display button to the viewer terminal 3 in a manner that allows an object display instruction to be input once every predetermined time for all topics. According to this example, the number of times an action can be performed by a viewer for any topic is limited. Therefore, the video distribution device 1 can prevent the same viewer from repeatedly pressing the object display button for any topic.

[0165] (effect) As described above, according to this embodiment, a video distribution system that distributes live broadcast content obtained from a distributor terminal used by a distributor to a viewer terminal used by a viewer transmits first content display data for displaying the shared content to the distributor terminal, and transmits second content display data for displaying the shared content to the viewer terminal. As a result, the video distribution system can transmit shared content to a distributor terminal and a viewer terminal and display the shared content while distributing video content. The video distribution system can provide topics that can be shared between a distributor and a viewer based on the shared content. The distributor and the viewer can actively communicate with each other by sharing the provided topics. In this way, the video distribution system can support communication between the distributor and the viewer. The video distribution system also transmits an element that allows an instruction to select content from a list to the distributor terminal, and transmits an element that allows an instruction to display an object from the list to the viewer terminal. As a result, the video distribution system can cause the viewer and the distributor to share content selected by the distributor. The video distribution system can cause an object based on an operation by the viewer to be shared with the distributor. Therefore, the video distribution system can receive different instructions from the distributor and the viewer, and cause communication to be performed according to each instruction. As a result, the video distribution system can support communication between the distributor and the viewer.

[0166] According to this embodiment, in a video distribution system, first content display data includes a list of contents and includes data for displaying a first element into which a selection instruction can be input to display at least a portion of the selected content included in the list of contents, and the video distribution system transmits selected content display data for displaying at least a portion of the selected content to a distributor terminal and a viewer terminal based on the selection instruction by the distributor via the first element. In this way, the video distribution system can allow the distributor to share content selected by the distributor with the viewer based on the distributor's operation. The video distribution system can allow the distributor and the viewer to communicate with each other based on the content selected by the distributor. In this way, the video distribution system can support communication between the distributor and the viewer.

[0167] According to this embodiment, in a video distribution system, the second content display data includes a list of contents and includes data for displaying a second element into which a display instruction can be input to display an object for object display target content included in the list of contents, and the video distribution system transmits object display data for displaying an object for the object display target content to a distributor terminal and a viewer terminal based on the display instruction from a viewer via the second element. This allows the video distribution system to share objects for content selected by a viewer based on the viewer's operation. For example, the viewer can convey his or her interest in content to the distributor via the object. The distributor can recognize that the viewer is interested in the content in which the object is displayed. The distributor can select content from the list based on the viewer's interest. This allows the video distribution system to stimulate communication between the distributor and the viewer. This allows the video distribution system to support communication between the distributor and the viewer.

[0168] According to this embodiment, the video distribution system switches between displaying a list of content and displaying selected content based on a selection instruction from a distributor. This allows the video distribution system to change information shared between a distributor and a viewer based on the distributor's operation.The video distribution system allows information content to be shared between a distributor and a viewer at the distributor's initiative.This allows the video distribution system to support distributor-initiated communication between a distributor and a viewer.

[0169] According to this embodiment, the selected content display data includes link information related to the selected content. For example, distributors and viewers can obtain detailed information related to the selected content by accessing the collection source page of the selected content. Therefore, distributors and viewers can further expand the topic based on the detailed information. This allows the video distribution system to stimulate communication between distributors and viewers. In this way, the video distribution system can support communication between distributors and viewers.

[0170] According to this embodiment, the object is hidden based on the lapse of a predetermined time. Therefore, the video distribution system can sequentially update the display of the object and display the action of the viewer in real time. The viewer can, for example, give an instruction to display the object at any time so as not to erase the object. This allows the video distribution system to stimulate communication between the distributor and the viewer. In this way, the video distribution system can support communication between the distributor and the viewer. Furthermore, the video distribution system can limit the number of objects to be displayed by sequentially erasing the objects. Therefore, the video distribution system can reduce the amount of processing required for object display processing.

[0171] According to this embodiment, the video distribution system limits the number of display instructions that a viewer can input within a given time period. This allows the video distribution system to prevent the viewer from repeatedly inputting display instructions for objects. As a result, the video distribution system can reduce the amount of processing required for object display processing.

[0172] According to this embodiment, the video distribution system limits the number of objects displayed within a given time. This allows the video distribution system to prevent a large number of objects from being displayed in a crowded state, making the objects easier to see. In addition, the video distribution system can reduce the amount of processing required for object display processing.

[0173] According to this embodiment, in the video distribution system, the list of contents is a list in which the contents are arranged in a predetermined order. For example, the video distribution system can display the list based on access rankings. Therefore, the video distribution system can provide topics that are likely to interest or concern the distributor or the viewer. In this way, the video distribution system can stimulate communication between the distributor and the viewer by sharing topics that are likely to interest or concern the distributor. In this way, the video distribution system can support communication between the distributor and the viewer.

[0174] (Other embodiments) In the above embodiment, the video distribution device 1 has been described as an example of distributing live broadcast content to the viewer terminal 3. However, the video distribution device 1 may distribute video content of time shift distribution to the viewer terminal 3. In this case, the video distribution device 1 transmits data for displaying information content displayed for the live broadcast content corresponding to the video content of time shift distribution to the viewer terminal 3 in addition to the video content data. For example, the video distribution device 1 may transmit the second list display data to the viewer terminal 3 with the second element included in the second list display data in an inactive state. The viewer cannot perform an action on the list display image. The viewer cannot input an object display instruction. For example, the video distribution device 1 may transmit the second selected content display data to the viewer terminal 3 with the second element included in the second selected content display data in an active state. The viewer may perform an operation on the selected content image. The viewer can select the full text display button to input a full text display instruction. The viewer can select the full text display button to input an access instruction.

[0175] According to this example, even in time-shift distribution, video distribution device 1 can display information content, allowing information to be shared between the distributor and the viewer. Even in time-shift distribution, video distribution device 1 can accept operations on selected content by the viewer.
