Furthermore, definition files and various information tables used at the time of execution of the program are also stored in the external memory 211, and a detailed description of these will be described later. The above is the description of an example of the hardware configuration of various devices in the teleconference system 1.

  Next, an example of a functional configuration of the teleconference system 1 will be described with reference to FIG. FIG. 3 is a block diagram showing an example of a functional configuration of the teleconference system 1. The functional units 11 to 16 shown in FIG. 3 are functional units included in the remote conference application (client application) installed in the client terminal 10. The functional units 21 to 27 illustrated in FIG. 3 are functional units included in the teleconference application (server application) installed in the teleconference server 20.

  First, the functional configuration of the client terminal 10 will be described. The client terminal 10 functionally includes an entry request unit 11, a group generation request unit 12, a transmission data storage unit 13, a transmission control unit 14, a content reception control unit 15, and an output unit 16. . The group generation request unit 12 may include only the client terminal 10X of the chairman user, and may not include the client terminals 10A to 10D of other general users.

  The entry request unit 11 transmits an entry request by the user of the client terminal 10 to the entry processing unit 21 of the remote conference server 20. The entry request is a request for entry of a room that the user wants to join. The entry request unit 11, for example, receives an entry request based on a user operation.

  Specifically, when the login of the user to the remote conference server 20 using the user ID is successful, a menu screen including a "conference room reservation" button is displayed on the display screen of the client terminal 10. When the pressing of the "Conference room reservation" button on the menu screen is accepted, the display screen displays a participation destination selection screen for selecting the meeting to be joined (the room to which the participating meeting is to be held). Ru. In the participation destination selection screen, when the selection of the meeting to be joined is accepted by the user operation, the entry request unit 11 transmits an entry request for the selected meeting (room) to the entry processing unit 21.

  The room entry request transmitted by the room entry request unit 11 includes user ID information, language information of the OS, and a chairman flag. The user ID information is information indicating the ID of the user. The language information of the OS is information indicating the language of the OS of the client terminal 10. The language of the OS is, for example, various languages such as Japanese or English.

  The chairman flag is a flag indicating whether the user is a chairman user or not. For example, it is indicated by “1” when the user is the chairman user and “0” when the user is a general user other than the chairman user. Be Whether or not the user is a chairperson user is preset, for example, at the time of booking a room.

  The group generation request unit 12 transmits a grouping request to the attribute information acquisition unit 22 of the remote conference server 20. A grouping request is a request for grouping client terminals 10A to 10D of general users in the same room. The group generation request unit 12 receives a grouping request, for example, based on a user operation of the chairman user (depression of the grouping start button 30 shown in FIG. 10). The grouping request may be received based on an operation of a general user.

  In addition, the group generation request unit 12 transmits a group division release request to the group generation unit 23 of the remote conference server 20. The grouping release request is a request for releasing the grouping of the grouped client terminals 10A to 10D. The group generation request unit 12 receives a grouping cancellation request based on, for example, a user operation of the chairman user (depression of the grouping cancellation button 32 shown in FIG. 11). Note that the grouping cancellation request may be received based on the general user's operation.

  The transmission data storage unit 13 is a storage unit (queue) that stores the same information as the information transmitted by the transmission control unit 14. The transmission data storage unit 13 has, for example, an audio cue and an image cue. The voice cue is a cue for voice information collected by the microphone function of the client terminal 10. In the voice queue, voice information collected intermittently by the microphone function of the client terminal 10 is sequentially stored.

  The image queue includes an image queue for a captured image (meeting image) captured by the camera function of the client terminal 10, and an image queue for a designated image (such as an image of a desktop screen of the client terminal 10) designated by a user operation. Is included.

  The captured images are sequentially stored in the image queue for the captured image. The camera function of the client terminal 10 intermittently performs imaging processing (imaging of a moving image and input of the moving image to the client terminal 10). Therefore, in the image queue for captured images, a plurality of images constituting a moving image are sequentially stored for each frame in the moving image.

  A designated image is stored at predetermined time intervals in the image queue for the designated image. In the image queue for the designated image, for example, desktop images displayed on the desktop screen of the client terminal 10 are sequentially stored every 0.2 seconds. Each designated image to be stored is, for example, one frame of a moving image to be reproduced by joining desktop images.

  The transmission control unit 14 transmits media data (transmission information) to be transmitted from the client terminal 10 of the transmission source to the client terminal 10 of the transmission destination in the remote conference to the reception control unit 26 of the remote conference server 20. Media data is, for example, a voice collected by a microphone function, an image (video) captured by a camera function, or a designated image designated as an image sharing a display by user operation (the entire desktop or a screen of a designated application) Image) and so on.

  The content reception control unit 15 requests the distribution control unit 25 of the remote conference server 20 to start communication. Specifically, the content reception control unit 15 stores the user information in the same room notified by the room entry processing unit 21 described later. The content reception control unit 15 opens a socket necessary for distributing the content from the remote conference server 20 to the client terminal 10 based on the stored user information in the same room. The content reception control unit 15 receives the content output from the distribution control unit 25 by requesting the distribution control unit 25 to start communication accompanied by the opening of the socket. The content reception control unit 15 outputs the received content to the output unit 16.

  The output unit 16 outputs the content output from the content reception control unit 15. Specifically, image data as content is displayed on the conference screen, or audio data as content is output by the speaker function. The output unit 16 switches the display of the conference screen based on the result of the grouping execution from the group generation unit 23 of the remote conference server 20. The output unit 16 may perform an output to notify that effect when the room entrance processing unit 21 notifies that the user has entered the room.

  Next, the functional configuration of the teleconference server 20 will be described. Functionally, the remote conference server 20 has an entry processing unit 21 (entry processing unit), an attribute information acquisition unit 22 (attribute information acquisition unit), a group generation unit 23 (group generation unit), and a distribution information acquisition unit 24 (distribution information acquisition means), a distribution control unit 25, a reception control unit 26, and a reception data storage unit 27.

  When the room entry processing unit 21 receives the room entry request transmitted from the room entry request unit 11 of the client terminal 10, the room entry processing unit 21 executes room entry processing. The entry process is a process of entering a user into a requested room, and for example, a process of storing in which room, which user and which client terminal 10 have entered the room. In the present embodiment, user ID information, OS language information, and a chairperson flag included in the room entry request are stored as room entry processing.

  FIG. 4 is a diagram showing an example of a database of information stored by the room entry processing unit 21. As shown in FIG. The database shown in FIG. 4 stores the user ID indicated by the user ID information, the OS language indicated by the OS language information, and the numerals indicated by the chairman flag. As shown in FIG. 4, the room entry processing unit 21 stores the OS language and the chairperson flag in association with the user ID. The entry processing unit 21 manages a database as shown in FIG. 4 for each room.

  The user whose user ID is “user X” shown in FIG. 4 corresponds to the user of the client terminal 10X. Each user of user ID "user A", "user B", "user C", and "user D" shown in FIG. 4 corresponds to each user of the client terminals 10A, 10B, 10C and 10D.

  When the room entry processing unit 21 performs room entry processing for one user, the room entrance processing unit 21 notifies other users in the room in which the room entry processing has been performed that there is room for the one user. For example, the entry processing unit 21 transmits, to the output unit 16 of the client terminal 10 of another user, information indicating that there is entry of one user.

  The entry processing unit 21 instructs the content reception control unit 15 of the client terminal 10 of the user who has performed the entry process to obtain information on other users in the room in which the entry process has been performed (hereinafter, “user information in the same room” Also known). The user information in the same room is information indicating which other users are in the same room, and is used, for example, to open a socket necessary for content distribution.

  The attribute information acquisition unit 22 acquires user attribute information of the client terminal 10 from the client terminal 10. The user attribute information is information indicating an attribute of the user, and in the present embodiment, is OS language information.

  The attribute information acquisition unit 22 extracts and acquires user attribute information for each user from the information stored by the room entry processing unit 21. The attribute information acquisition unit 22 acquires user attribute information, for example, at the timing when the grouping request is transmitted from the group generation request unit 12 of the client terminal 10.

  Specifically, from the database shown in FIG. 4, the attribute information acquisition unit 22 determines that the OS language of each user whose user ID is “user A” and “user B” is “English” and the user ID is “user OS language information indicating that the OS language of each user who is “X”, “user C”, and “user D” is “Japanese” is acquired. The attribute information acquisition unit 22 outputs the acquired OS language information (user attribute information) to the group generation unit 23.

  The group generation unit 23 divides the plurality of client terminals 10 into a plurality of groups based on the OS language information acquired by the attribute information acquisition unit 22. The group generation unit 23 generates a group for client terminals 10A to 10D of general users other than the chairperson user.

  Specifically, based on the OS language information output from the attribute information acquisition unit 22, the group generation unit 23 generates a group such that users having the same OS language are in the same group for the client terminals 10A to 10D. That is, the group generation unit 23 sets the client terminals 10A and 10B of “user A” and “user B” whose OS language is “English” as “group 1” and the user whose OS language is “Japanese” The client terminals 10C and 10D of “C” and “user D” are classified into “group 2”, and grouping is performed.

  The group generation unit 23 stores group information indicating the generated group. FIG. 5 is a diagram showing an example of a database indicating group information stored by the group generation unit 23. The database shown in FIG. 5 stores a group ID for identifying a group and a user ID. As shown in FIG. 5, the group generation unit 23 stores the group ID and the user ID in association with each other.

  When the group cancellation request is transmitted from the group generation request unit 12, the group generation unit 23 cancels the grouping of the client terminals 10A to 10E.

  The group generation unit 23 outputs the result of the grouping execution (the result of the grouping or the result of canceling the grouping) to the distribution information acquiring unit 24. Further, the group generation unit 23 notifies the output unit 16 of each client terminal 10 of the result of the grouping execution.

  The distribution information acquisition unit 24 acquires content (distribution information) which is information to be distributed to each client terminal 10 of the transmission destination by the distribution control unit 25. The content is acquired based on the media data stored in the reception data storage unit 27. The distribution information acquisition unit 24 outputs the acquired content to the distribution control unit 25.

  When the group generation unit 23 outputs the result of the grouping execution, the distribution information acquisition unit 24 acquires the content based on the output result. When the grouping by the group generation unit 23 is not executed (when the grouping is canceled), the distribution information acquisition unit 24 determines the content based on the media data from all the client terminals 10 in the same room. To get

  For example, the distribution information acquisition unit 24 acquires content to be distributed to the client terminal 10X based on media data from all the other client terminals 10A to 10D other than the client terminal 10X.

  In addition, when media data are an audio | voice, you may acquire the information which synthesize | combined (mixed) the media data from each client terminal 10A-10D as a content. The distribution information acquisition unit 24 acquires the content to be distributed to all the client terminals 10 in the same room in the same manner.

  Further, when the grouping by the group generation unit 23 is executed, the distribution information acquisition unit 24 acquires content based on the groups divided by the group generation unit 23.

  Specifically, the distribution information acquisition unit 24 acquires content between client terminals 10 in the same group (a group divided by the group generation unit 23 is the same group). The distribution information acquisition unit 24 acquires the content to the client terminal 10 of the transmission destination in the same group based on the media data from the client terminal 10 of the transmission source in the same group.

  For example, the distribution information acquisition unit 24 acquires media data from the client terminal 10B belonging to the same "group 1" as the content to be distributed to the client terminal 10A belonging to the "group 1". Further, the distribution information acquisition unit 24 acquires media data from the client terminal 10A belonging to the same "group 1" as the content to be distributed to the client terminal 10B belonging to the "group 1".

  When there are other client terminals belonging to “group 1” in addition to the terminals 10A and 10B, media data from other client terminals are also acquired as contents to be distributed to the respective client terminals 10A and 10B. In addition, media data from the client terminal 10X of the chairman user may also be acquired as content to be distributed to each of the client terminals 10A and 10B.

  The distribution information acquiring unit 24 acquires the contents to be distributed also for the client terminals 10C and 10D belonging to the "group 2" in the same manner as the client terminals 10A and 10B belonging to the "group 1".

  Note that the distribution information acquisition unit 24 may acquire the content to be distributed to the client terminal 10X of the chairman user regardless of whether the grouping is performed by the group generation unit 23. For example, even when grouping is performed by the group generation unit 23, the distribution information acquiring unit 24 operates as content to be distributed to the client terminal 10X in the same manner as when grouping is not performed. Media data from all the respective client terminals 10A to 10D may be acquired.

  The distribution control unit 25 outputs the content output from the distribution information acquisition unit 24 to the content reception control unit 15 of each client terminal 10 of the request source that requests distribution.

  The reception control unit 26 receives media data transmitted from the transmission control unit 14 of the client terminal 10. The reception control unit 26 outputs the received media data to the reception data storage unit 27.

  The reception data storage unit 27 stores media data received by the reception control unit 26. The received data storage unit 27 has an audio cue and an image cue.

  Next, with reference to FIGS. 6 to 9, the processes and operations executed by the teleconference system 1 configured as described above, that is, the control method of the teleconference system 1 will be described.

  In the following description of the flowchart, among the processes in the remote conference system 1, the room entry process, the grouping execution process, and the process after the grouping cancellation will be described with particular attention. FIG. 6 is a flowchart showing an example of the flow of the room entry process. FIG. 7 is a flowchart showing an example of the flow of grouping execution processing. FIG. 8 is a flowchart showing details of the content acquisition process in FIG. FIG. 9 is a flow chart showing an example of the flow of processing after grouping release.

  In the example shown in FIG. 6, the case where there is a room entry request from the client terminal 10A will be described as an example.

  As shown in FIG. 6, when the entry request is sent by the entry request unit 11 of the client terminal 10A (step S301), the entry request is received by the entry processing unit 21 of the remote conference server 20 (step S302). ). Subsequently, the room entry processing unit 21 executes the room entry processing (step S303). Specifically, the entry processing unit 21 analyzes parameters of the entry request, and acquires user ID information, OS language information, and a chairman flag.

  Subsequently, the room entry processing unit 21 stores the acquired user ID information, the OS language information, and the chairperson flag for the room for which the room entry request has been made (step S304). Subsequently, the entry processing unit 21 indicates that the user of the client terminal 10A has entered the room, the outputs of the other client terminals 10 (client terminals 10X, 10B to 10E) entering the room where the entry processing has been performed. It is notified to the part 16 (step S305).

  Subsequently, the entry processing unit 21 notifies the content reception control unit 15 of the client terminal 10A that made the entry request of the user information in the same room (which other users are entering the same room). (Step S306).

  Subsequently, the content reception control unit 15 of the client terminal 10A stores the user information in the same room notified by the room entry processing unit 21 (step S307).

  Subsequently, the content reception control unit 15 of the client terminal 10A requests the distribution control unit 25 of the remote conference server 20 to start communication (step S308). Specifically, based on the user information in the same room notified by the room entry processing unit 21, the content reception control unit 15 opens a required number of sockets and requests communication start. The number of sockets is, for example, one for audio and the other for video. The socket may be opened from the teleconference server 20 side.

  Subsequently, the distribution control unit 25 of the remote conference server 20 starts distribution of the content in response to the communication start request from the client terminal 10A (step S309).

  Next, the grouping execution process will be described with reference to the flowcharts shown in FIGS. 7 and 8 and the conference screens shown in FIGS. In the example illustrated in FIG. 7, an example in which grouping is performed by the client terminal 10X of the chairman user will be described.

  10 and 11 are diagrams showing a conference screen displayed on the client terminal 10X of the chairman user. FIG. 10 shows a conference screen before grouping execution, and FIG. 11 shows a conference screen after grouping execution. 12 and 13 are diagrams showing a conference screen displayed on the client terminal 10A of the general user. FIG. 12 shows a conference screen before grouping execution, and FIG. 13 shows a conference screen after grouping execution.

  As shown in FIG. 7, first, a grouping request is transmitted from the group generation request unit 12 of the client terminal 10X to the attribute information acquisition unit 22 of the remote conference server 20 (step S401).

  The group generation request unit 12 receives a grouping request, for example, by accepting the pressing by the user of the grouping start button 30 on the conference screen before the grouping execution shown in FIG. As shown in FIG. 10, each user (user A, user B, user C, user D) in the same room is displayed in the conference window 31 on the conference screen of the chairperson user before grouping execution. There is.

  Subsequently, the attribute information acquisition unit 22 of the remote conference server 20 receives a grouping request from the group generation request unit 12 of the client terminal 10X (step S402). Subsequently, the OS language information for each user other than the chairperson user is acquired by the attribute information acquisition unit 22 from the information stored by the room entry processing unit 21 in step S304 (step S403). The OS language information acquired by the attribute information acquisition unit 22 is output from the attribute information acquisition unit 22 to the group generation unit 23.

  Subsequently, based on the OS language information acquired in step S403, the group generation unit 23 divides the client terminals 10A to 10D into a plurality of groups (step S404). Specifically, each user terminal 10A, 10B of a user (user A, user B) whose OS language is "English" is a "group 1", and a user whose user is an OS language "Japanese" (user C, The client terminals 10C and 10D of the user D) are set to "group 2".

  Subsequently, the group generation unit 23 notifies each client terminal 10 of the result of grouping execution (step S405). Specifically, information indicating the result of grouping execution is transmitted from the group generation unit 23 to the output unit 16 of each client terminal 10.

  The output unit 16 switches and displays the conference screen on the basis of the result of the grouping execution notified in step S405 (step S406).

  For example, on the conference screen of the chairperson user after the grouping is performed, as shown in FIG. 11, frame images 41 and 42 surrounding the user for each group are displayed in the conference window 31. That is, it is shown that grouping has been performed on the conference screen. In addition, in place of the grouping start button 30, a grouping release button 32 is displayed on the conference screen of the chairman user after the grouping is performed.

  As shown in FIG. 12, the chairperson user is displayed on the conference window 31 of the conference screen of the user A before grouping execution. As shown in FIG. 13, the user B in the same group is displayed in the meeting window 31 of the meeting screen of the user A after the grouping is performed. That is, the conference screen of the user A is switched from the display of the chairperson user to the display of the user B of the same group by grouping execution. Similarly, on the conference screen of the user B, the display of the chairperson user is switched to the display of the user A in the same group by grouping execution.

  Similarly, on the conference screen of the user C, the display of the chairperson user is switched to the display of the user D in the same group by grouping execution. Similarly, with regard to the conference screen of the user D, the display of the chairperson user is switched to the display of the user C in the same group by grouping execution.

  Following step S406, the transmission control unit 14 of each client terminal 10 transmits the media data to the reception control unit 26 of the teleconference server 20 (step S407). Subsequently, the media data transmitted in step S407 is received by the reception control unit 26 of the remote conference server 20 (step S408). The media data received by the reception control unit 26 is stored in the reception data storage unit 27.

  Subsequently, the distribution information acquisition unit 24 acquires the content to be distributed to the general user based on the group (step S409). Specifically, based on media data of the client terminals 10 in the same group among the media data stored by the received data storage unit 27, the distribution information acquisition unit 24 transmits the data among the client terminals 10 in the same group. Content is acquired. The content to be delivered to the chairman user is acquired based on the media data of all the client terminals 10A to 10B.

  The content acquisition process based on the group in step S409 will be described with reference to FIG. 8 by taking the case where the media data is audio data as an example. In the process shown in FIG. 8, as a premise, there are other users belonging to "group 1" besides user A and user B, and others belonging to "group 2" other than user C and user D. It is assumed that there exist users of.

  The process shown in FIG. 8 is repeated until content is acquired for all the users in the same room, for example. For example, as the process of acquiring the content distributed to the user A, first, the voice queue of the user belonging to the same group as the user A stored in the received data storage unit 27 is referred to (S4091). Subsequently, voice data of users (user B and other users belonging to “group 1”) belonging to the same group is acquired from the voice queue to be referred to (S4092).

  Subsequently, the acquired voice data of each user is synthesized (mixed), and the synthesized result is acquired as content (S4093). Subsequently, the content (synthesized speech data) acquired in S4093 is output to the distribution control unit 25 (S4094). When the above processes S4091 to S4094 are repeated for all users, the content acquisition process for audio data ends, and the process of step S409 ends. If there is no other user who belongs to the same group, or if the media data is an image, etc., the combining process of step S4093 described above is omitted.

  When the content is acquired in step S409 shown in FIG. 7, the distribution control unit 25 distributes the content to each client terminal 10 (step S410). Thus, the grouping execution process ends.

  Next, the process after releasing the grouping will be described with reference to the flowchart shown in FIG. 9 and the conference screen shown in FIGS. In the example shown in FIG. 9, an example in which the grouping is released by the client terminal 10X of the chairman user will be described.

  As shown in FIG. 9, first, the group generation cancellation request is transmitted to the group generation unit 23 of the remote conference server 20 by the group generation request unit 12 of the client terminal 10X (step S501). For example, in the conference screen after the grouping execution shown in FIG. 11, the group generation request unit 12 receives the pressing of the grouping cancellation button 32 by the user, and thereby accepts the grouping cancellation request.

  Subsequently, the group generation unit 23 receives the grouping cancellation request transmitted in step S501 (step S502). Subsequently, the group generation unit 23 notifies each client terminal 10 of the result of releasing the grouping (Step S503). Specifically, information indicating the result of degrouping is transmitted from the group generation unit 23 to the output unit 16 of each client terminal 10.

  Subsequently, the output unit 16 changes the display of the conference screen based on the cancellation result notified in step S503 (step S504). That is, it is shown on the conference screen that the grouping is released.

  For example, the conference screen of the chairman user is switched from the conference screen of FIG. 11 to the conference screen of FIG. 10 by the grouping cancellation. In the conference screen of the chairman user, the frame images 41 and 42 displayed in the conference window 31 disappear, and the grouping start button 30 is displayed in place of the grouping release button 32.

  The conference screen of the user A is switched from the conference screen of FIG. 13 to the conference screen of FIG. 12 by the grouping release. That is, the user displayed in the conference window 31 changes from the user B to the chairperson user. Similarly, with regard to the conference screen of the user B, the user displayed in the conference window 31 changes from the user A to the chairperson user by the grouping cancellation. The display of the user C and the user D also switches similarly.

  Following step S504, the transmission control unit 14 of each client terminal 10 transmits the media data to the reception control unit 26 of the remote conference server 20 (step S505). Subsequently, the media data transmitted in step S505 is received by the reception control unit 26 of the remote conference server 20 (step S506). The media data received by the reception control unit 26 is stored in the reception data storage unit 27.

  Subsequently, the distribution information acquisition unit 24 reacquires content to be distributed to users other than the chairperson (step S507). For example, content to be distributed to the client terminal 10A is acquired based on media data from all the client terminals 10X, 10B to 10D other than the client terminal 10A. The distribution information acquisition unit 24 outputs the reacquired content to the distribution control unit 25.

  Subsequently, the distribution control unit 25 distributes the content reacquired in step S507 to each client terminal 10 (S508). Thus, the process after the grouping release is completed.

  The process described above may be implemented as a program that causes the teleconference system 1 to function as the above-described functional units.

  As described above, according to the remote conference system 1 and its control method and program according to the present embodiment, the plurality of client terminals 10 can be divided into a plurality of groups based on the OS user attribute information of the client terminals 10. Therefore, appropriate grouping is performed based on the attributes of the user without the user having to register the group in advance. Then, based on media data from the client terminal 10 of the transmission source in the same group, the content to the client terminal 10 of the transmission destination in the same group is acquired. As a result, it becomes possible to transmit and receive information within the same group properly divided. As described above, it is possible to perform grouping appropriate for transmitting and receiving information without requiring time and effort of the user.

  Further, according to the teleconference system 1, the user attribute information is acquired based on the room entry processing unit 21 processing the room entry request from the client terminal 10. Therefore, grouping can be performed by automatically acquiring user attribute information in response to a room entry request without the user performing a special user operation or the like for acquiring user attribute information.

  Further, according to the teleconference system 1, grouping is performed based on the OS language information of the client terminal 10. Therefore, for example, client terminals 10 having the same OS language can be set as the same group, and in the same group, information can be appropriately transmitted and received between the client terminals 10 having the same OS language.

Second Embodiment
Next, a teleconference system according to the second embodiment will be described. The teleconference system according to the second embodiment includes the same elements and structures as the teleconference system 1 according to the first embodiment. Therefore, the same components and structures as those of the teleconference system 1 according to the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted, and parts different from the first embodiment will be described.

  FIG. 14 is a block diagram showing a functional configuration of the teleconference system according to the second embodiment. As shown in FIG. 14, in the second embodiment, the client terminal 10 includes an entry request unit 11, a group generation request unit 12, a transmission data storage unit 13, a transmission control unit 14, a content reception control unit 15, and an output unit. In addition to 16, an attribute information transmission unit 17 (attribute information transmission means) is provided. The client terminal 10 </ b> X of the chairman user may not have the attribute information transmission unit 17.

  The attribute information transmission unit 17 transmits user attribute information to the attribute information acquisition unit 22 of the remote conference server 20 from each of the client terminals 10A to 10D of the general user. That is, in the present embodiment, user attribute information is transmitted separately from the room entry request transmitted by the room entry request unit 11.

  The attribute information transmission unit 17 may transmit the user attribute information instead of the user attribute information included in the room entry request transmitted by the room entry request unit 11, and in addition to the user attribute information included in the room entry request, User attribute information may be sent.

  In this embodiment, not the OS language information but the number of transmissions of transmission information from the client terminals 10A to 10D of the transmission source (hereinafter, also referred to as "the number of transmissions of the client terminals 10A to 10D") is used as user attribute information. More specifically, the user attribute information is the number of utterances of the user during the meeting.

  The transmission count of the client terminals 10A to 10D is stored, for example, in the transmission data storage unit 13 for each of the client terminals 10A to 10D. The attribute information transmission unit 17 transmits the number of transmissions of each of the client terminals 10A to 10D stored in the transmission data storage unit 13 to the attribute information acquisition unit 22 at a predetermined timing. That is, the attribute information transmission unit 17 transmits the number of transmissions of each of the client terminals 10A to 10D within the predetermined period to the attribute information acquisition unit 22.

  The timing at which the number of times of transmission of each of the client terminals 10A to 10D is transmitted by the attribute information transmission unit 17 is, for example, the timing at which the grouping request is received by the attribute information acquisition unit 22 while a meeting in a room is being held. It is. When the information indicating that the grouping request has been received is transmitted from the attribute information acquiring unit 22, the attribute information transmitting unit 17 transmits the number of transmissions of each of the client terminals 10A to 10D.

  When receiving the grouping request from the group generation request unit 12, the attribute information acquisition unit 22 notifies the attribute information transmission unit 17 of the client terminals 10A to 10D of the general user that the grouping request has been received.

  The attribute information acquisition unit 22 receives the number of transmissions of each of the client terminals 10A to 10D transmitted from the attribute information transmission unit 17. Thereby, the attribute information acquisition unit 22 acquires the number of transmissions of each of the client terminals 10A to 10D as the user attribute information. The attribute information acquisition unit 22 outputs the acquired number of transmissions of each of the client terminals 10A to 10D to the group generation unit 23.

  The group generation unit 23 divides the plurality of client terminals 10A to 10D into a plurality of groups based on the number of transmissions of each of the client terminals 10A to 10D output from the attribute information acquisition unit 22. For example, the group generation unit 23 generates a group so that the total number of transmissions of each of the client terminals 10A to 10D in the same group (hereinafter, also referred to as “intra-group total transmission number”) is not too biased for each group. Do. More specifically, the group generation unit 23 performs grouping so that the difference between the total number of times of transmission within the group for each group is equal to or less than a predetermined threshold.

  Next, with reference to FIG. 15, the grouping execution process in the present embodiment will be described. FIG. 15 is a flowchart showing an example of the flow of grouping execution processing according to the second embodiment.

  As shown in FIG. 15, first, the grouping request is transmitted to the attribute information acquiring unit 22 of the remote conference server 20 by the group generation request unit 12 of the client terminal 10X of the chairman user (step S601), and the remote conference server The grouping request from the group generation request unit 12 of the client terminal 10X is received by the 20 attribute information acquisition units 22 (step S602).

  When the grouping request is received in step S602, the attribute information acquiring unit 22 of the remote conference server 20 notifies the attribute information transmitting unit 17 of each of the client terminals 10A to 10D that the grouping request has been made ( Step S603). Subsequently, the attribute information transmission unit 17 receives information indicating that a grouping request has been made (step S604). Subsequently, the number of transmissions of each of the client terminals 10A to 10D is transmitted by the attribute information transmission unit 17 to the attribute information acquisition unit 22 of the remote conference server 20 (step S605).

  Subsequently, the number of transmissions of each of the client terminals 10A to 10D transmitted in step S605 is received by the attribute information acquisition unit 22 (step S606). The number of transmissions of each of the client terminals 10A to 10D received by the attribute information acquisition unit 22 is output from the attribute information acquisition unit 22 to the group generation unit 23.

  Subsequently, the group generation unit 23 divides the client terminals 10A to 10D into a plurality of groups based on the number of transmissions of each of the client terminals 10A to 10D received in step S606 (step S607).

  The subsequent process is the same as the process of steps S405 to S410 shown in FIG.

  As described above, according to the remote conference system of the present embodiment, along with the transmission of the user attribute information from the client terminal 10 by the attribute information transmission unit 17, the user attribute information is acquired by the attribute information acquisition unit 22. Therefore, grouping can be easily performed based on the user attribute information transmitted from the client terminal 10.

For example, grouping may be performed based on the OS language information of each client terminal 10, and grouping may be re-executed based on the number of transmissions of each client terminal 10 at a predetermined timing.

  The user attribute information is not limited to the example described in the above embodiment. For example, screen information shared on the conference screen of each client terminal 10, file information opened in each client terminal, or a user of each client terminal Identification information (such as gender or age) may be used. In the case of using the shared screen information as the user attribute information, instead of acquiring the OS language information in step S403, the shared information may be acquired, and the grouping may be performed based thereon. Also in the case of using open file information or identification information of a user (such as gender or age), each information may be acquired in step S403, and grouping may be performed based thereon. It goes without saying that grouping can be performed using a plurality of pieces of user attribute information.
