<Remote conference system>
An outline of the remote conference system 10 will be described with reference to FIG. As shown in FIG. 1, the remote conference system 10 includes a server device 20 and a terminal device operated by a plurality of users attending the conference. In FIG. 1, three terminal devices are shown. The number of terminal devices varies depending on the situation of the remote conference to be performed. In the embodiment, a remote conference using three terminal devices will be described as an example. The three terminal devices shown in FIG. 1 are referred to as terminal devices 41, 42, and 43, respectively. The terminal devices 41, 42, and 43 are respectively operated by users who are attending the same remote conference.

  Server device 20 and terminal devices 41, 42, 43 are connected to network 90. The network 90 is, for example, a network such as the Internet or a local area network (LAN). In the remote conference system 10, the remote conference by the terminal devices 41, 42, and 43 is performed in a state where a session is established between the server device 20 and each of the terminal devices 41, 42, and 43.

  The server device 20 relays data transmitted and received between the terminal devices 41, 42, and 43. As data transmitted / received between the terminal devices 41, 42, and 43, for example, photographing data captured by each of the terminal devices 41, 42, and 43 and sound collected by each of the terminal devices 41, 42, and 43 are collected. Sound data can be listed. Further, the server device 20 relays the material data. The document data is image data corresponding to a document image 64 (see the lower part of FIG. 3 described later) used in the remote conference. The document data may be image data corresponding to a plurality of pages of document images 64. In the remote conference system 10, as in the known remote conference system, the remote conference can proceed while the document images 64 corresponding to the same document data are shared between the terminal devices 41, 42, and 43. The server device 20 transmits the material data transmitted from any one of the terminal devices 41, 42, and 43 to the other two terminal devices.

  The remote conference executed via the server device 20 is identified by the conference ID. That is, the remote conference by the terminal devices 41, 42, and 43 is distinguished from other remote conferences executed via the server device 20 by the conference ID. In the remote conference identified by the conference ID, the terminal devices 41, 42, and 43 are identified by the terminal ID. In the embodiment, the terminal IDs of the terminal devices 41, 42, and 43 are as follows. The terminal ID of the terminal device 41 is “USER41”. The terminal ID of the terminal device 42 is “USER42”. The terminal ID of the terminal device 43 is “USER43”.

  In the remote conference identified by the conference ID, a predetermined role and authority are set for each of the terminal devices 41, 42, and 43. The role is exemplified by the organizer, the presenter, and the participant. Of these three roles, the organizer is the highest role, and the presenters and participants are lower than the organizer. The presenter has a higher role than the participants. For example, in a terminal device in which the role is set to the organizer or the presenter, an operation for transmitting material data is permitted, but in a terminal device in which the role is set to a participant, this operation cannot be performed. In addition, in the terminal device in which the role is set to the organizer, an operation to change the role set in the other terminal device to a different role is permitted, but the terminal device in which the role is set to the presenter or the participant Then, this operation cannot be performed.

  The authority is exemplified by page change. The page change is an authority to display any page without limitation, that is, to change the displayed page when the document data corresponds to the document image 64 for a plurality of pages. In the terminal device in which the page change is not set as the authority, the change of the page of the displayed material is restricted, and the image of the page specified by the terminal device that is the source of the material data is displayed. That is, during a remote conference, a terminal device for which no page change is set displays an image of the same page as the terminal device that is the source of the material data. In the embodiment, an organizer, a presenter, and a participant are examples of roles, and a page change is an example of authority.

  In the remote conference system 10, the terminal devices 41, 42, and 43 are classified into one or a plurality of groups. The group to which the terminal devices 41, 42, and 43 belong is identified by, for example, an account. In the remote conference system 10, an account necessary for using the provided remote conference service is issued by a company operating the remote conference system 10. For example, when a user who manages the terminal devices 41, 42, and 43 has applied for issuance of accounts for three units, an account with a maximum number of terminals of three is issued from the business operator to this user. Is done. The terminal devices 41, 42, and 43 use this account to establish a session with the server device 20. By establishing a session, a remote conference using the terminal devices 41, 42, and 43 becomes possible. In this case, the groups to which the terminal devices 41, 42, and 43 belong are the same group with a common account.

  In addition, when the first user who manages the terminal devices 41 and 43 makes an application for the issuance of accounts for two devices, the maximum number of terminals used by the operator is two for the first user. An account is issued. In addition to the above-mentioned issuance application, when the issuance application for one device is made by the second user who manages the terminal device 42, the maximum number of terminals used is one for the second user from the business operator. A second account is issued. The terminal devices 41 and 43 establish a session with the server device 20 using the first account. The terminal device 42 establishes a session with the server device 20 using the second account. By establishing a session, a remote conference using the terminal devices 41, 42, and 43 becomes possible. In this case, the group to which the terminal devices 41 and 43 belong becomes the first group by the common first account, and the group to which the terminal device 42 belongs becomes the second group by the second account. In addition, for example, when a remote conference program is executed in a single sign-on environment, a user account provided by a directory service such as an active directory may be imported as a user account of the remote conference system 10. In this case, the group set for the user account by the directory service is also applied to the remote conference system 10.

The server device 20 stores a connection list shown in FIG. In the connection list, the attribute information of the terminal devices 41, 42, and 43 with which the session is established is registered. The attribute information is the role, authority, and group described above. That is, the role, authority, and group are registered for each terminal ID of the terminal devices 41, 42, and 43 in the connection list. The registration state in the connection list shown in FIG. 2 is an example. In the connection list shown in the lower part of FIG. 2, the authority “−” set for the terminal ID “USER43” indicates that the page change is not set.

  In the remote conference system 10, a remote conference is reserved in advance by a user having an account. This user can set roles and privileges for attendees. The role of the user who hosted the remote conference is the host. The role and authority set here are the role corresponding to the terminal ID of the terminal device with which the session is established in the connection list when the session is established between the server device 20 and the terminal devices 41, 42, and 43, respectively. This is the initial setting of authority. The reservation is registered in a predetermined site provided by the server device 20. At the time of reservation, for example, the attendee can be notified of the remote conference. This notification is performed using e-mail, for example. That is, the date and time of the remote conference and the URL of the server device 20 are included in the body of the email. The URL of the server device 20 includes a conference ID for identifying a reserved remote conference and information related to attribute information. In the remote conference system 10, a user who does not have an account can be invited to the remote conference as an attendee. In this case, a group to which a terminal device used by a user who does not have an account belongs is classified into a group different from a group to which a terminal device used by a user who has an account belongs.

  That is, the role and authority are attribute information subordinate to each remote conference set in correspondence with the remote conference identified by the reserved conference ID. On the other hand, the group is attribute information that is set independently of the remote conference identified by the conference ID and is not subordinate to each remote conference. For example, one or both of the role and authority set for a predetermined terminal device in the first remote conference may be the same in the second remote conference different from the first remote conference. May be different. On the other hand, the group to which the above-mentioned terminal device belongs is the same in both the first remote conference and the second remote conference. A group is unique attribute information when using the remote conference system 10 in which a remote conference via the network 90 is realized.

  The terminal devices 41, 42, and 43 are, for example, personal computers, smartphones, or tablet terminals. That is, the terminal devices 41, 42, and 43 are the same or similar terminal devices that have a communication function via the network 90. Accordingly, the terminal devices 41, 42, and 43 have the same configuration. In the embodiment, the terminal device 41 will be described as an example. The server device 20 is a known server device having a hardware configuration similar to that of a server device in a known remote conference system. Therefore, the other description regarding the server apparatus 20 is abbreviate | omitted.

<Terminal device>
The terminal device 41 is demonstrated with reference to FIG.1 and FIG.3. As illustrated in FIG. 1, the terminal device 41 includes a CPU 47, a storage device 48, a RAM 49, a display unit 50, an operation unit 51, a speaker 52, a communication unit 53, and a connection interface 54. The CPU 47, the storage device 48, the RAM 49, the display unit 50, the operation unit 51, the speaker 52, the communication unit 53, and the connection interface 54 are connected to the bus 55. In the embodiment, the connection interface 54 is described as “connection I / F 54”. A camera 56 and a microphone 57 are connected to the connection I / F 54. As described above, the terminal devices 42 and 43 are the same or the same type of terminal device as the terminal device 41. Accordingly, the terminal devices 42 and 43 have the same configuration as the terminal device 41.

  The CPU 47 executes arithmetic processing. The storage device 48 is configured by a computer-readable storage medium. For example, the storage device 48 includes a hard disk and / or a flash memory. In addition, the storage device 48 may include a ROM. The storage device 48 stores various programs. For example, the OS and various applications are stored in the storage device 48. The application stored in the storage device 48 includes a program for each process (see FIGS. 4 to 6 and 9) to be described later executed by the terminal device 41.

  Each processing program may be installed in the storage device 48 in advance. The program for each process may be transmitted from the server device 20 to the terminal device 41 as a transmission signal via the network 90 when the terminal device 41 accesses the server device 20 when connecting to the remote conference. The program may be installed in the storage device 48 at that timing. In this case, the program may be stored in the RAM 49. The prior installation is performed, for example, by reading a program stored in a computer-readable storage medium such as a semiconductor memory by a reading unit (not shown) of the terminal device 41. For example, when the terminal device 41 includes an optical drive (not shown), the prior installation may be performed by reading a program stored in the optical medium by the optical drive. In addition, the prior installation is performed by a program stored in a computer-readable storage medium such as a hard disk of a server device (server device 20 or a server device not shown) connected to the terminal device 41 via the network 90. The communication unit 53 may receive the signal as a transmission signal. Which form is used is appropriately determined in consideration of various circumstances. The computer-readable storage medium may be a non-transitory storage medium that does not include a temporary storage medium (for example, a transmission signal). The non-temporary storage medium may be any storage medium that can store information regardless of the period in which the information is stored.

  The RAM 49 is a storage area used when the CPU 47 executes various programs. The RAM 49 stores predetermined data and information used in the process during the execution of the process. In the terminal device 41, the CPU 47 controls the terminal device 41 by executing the OS stored in the storage device 48 and the programs of the processes shown in FIGS. 4 to 6 and 9. Thereby, in the terminal device 41, various processes are performed.

  The display unit 50 is, for example, a liquid crystal display. Various information is displayed on the display unit 50. A remote conference screen 60 is displayed on the display unit 50. As shown in FIG. 3, the remote conference screen 60 includes a share button 61 and an end button 62. A captured image 63 is displayed on the remote conference screen 60. The remote conference screen 60 immediately after the session is established is, for example, in the form as shown in the upper part of FIG. That is, on the remote conference screen 60, the material image 64 or the material designation screen 65 (see FIG. 7 described later) is not displayed. The display of the material image 64 and the material designation screen 65 will be described later.

  The share button 61 is associated with a share start instruction. The sharing start instruction is an instruction for starting the material transmission process shown in FIGS. As described above, the terminal device whose role is set to the organizer or the presenter is permitted to transmit the material data, but the terminal device whose role is set to the participant cannot perform this operation. Therefore, when the role set in the terminal device 41 is a participant unlike FIG. 2, the sharing button 61 is not displayed or grayed out. The end button 62 is associated with the end of the remote conference. The user of the terminal device 41 presses the end button 62 when ending the remote conference. In this case, the remote conference is terminated, and the session established with the server device 20 is disconnected.

  The photographed image 63 is an image corresponding to video data from the terminal devices 42 and 43, for example. On the remote conference screen 60, it is also possible to display a captured image 63 corresponding to the video data captured by the own device. On the remote conference screen 60, display or non-display of the captured image 63 can be set. The display or non-display of the captured image 63 can be set individually for each captured image 63. Based on the remote conference screen 60 shown in FIG. 3 and FIG. 7 described later, the captured image 63 of the terminal device 41 whose terminal ID is “USER41” is set to non-display, and the terminal IDs are “USER42” and “USER43”. The captured images 63 of the terminal devices 42 and 43 are set to display. On the remote conference screen 60, two captured images 63 are displayed in accordance with display settings for the captured images 63 of the terminal devices 42 and 43. As will be described later, the document image 64 is displayed when the share button 61 is pressed on any one of the terminal devices 41, 42, and 43.

  The operation unit 51 receives inputs such as various instructions for the terminal device 41. The operation unit 51 includes a keyboard and a mouse. Although details are omitted, the process of generating operation information corresponding to each operation on the keyboard and mouse is a technique adopted in a known personal computer and is also adopted in the terminal device 41.

  The speaker 52 is a sound output unit that outputs sound. The output target of the speaker 52 is, for example, a sound corresponding to the sound data transmitted from the server device 20 described above. The communication unit 53 connects the terminal device 41 to the network 90 and performs data communication via the network 90. In the terminal device 41, various data are transmitted to and received from the server device 20 via the communication unit 53. The communication unit 53 is, for example, an interface circuit that conforms to the Ethernet (registered trademark) standard. The connection to the network 90 by the communication unit 53 may be either a wireless connection or a wired connection.

  The connection I / F 54 is an interface that connects a predetermined device to the terminal device 41. The connection I / F 54 is an interface including a USB (Universal Serial Bus) port, for example. The connection I / F 54 may include a wireless communication module. As the wireless communication module, a communication module compatible with Bluetooth (registered trademark) is exemplified. The camera 56 connected to the connection I / F 54 takes an external image. The terminal device 41 may be configured to incorporate a camera. The microphone 57 connected to the connection I / F 54 is a sound collection unit that collects external sound. For example, the microphone 57 collects sound uttered by the user of the terminal device 41.

  The terminal device 41 is different from a known communication device in that a program for each process described later (see FIGS. 4 to 6 and 9) is stored in the storage device 48 or the RAM 49. However, the terminal device 41 is the same as a known terminal device in hardware.

<Processing executed in terminal device>
Each process executed by the terminal device 41 when the remote conference by the terminal devices 41, 42, and 43 is executed will be described. Similar processing is executed in the terminal devices 42 and 43.

<Main processing>
The main process will be described with reference to FIG. At the start of the main process, the terminal device 41 receives an operation for designating the URL of the server device 20 via the operation unit 51. When this operation is input, the CPU 47 activates a main processing program. The main process is started by starting the main process program. The CPU 47 that has started the main process executes a connection process (S11). In the connection process, the terminal device 41 accesses the server device 20 and a session is established with the server device 20. In the connection process, a procedure similar to that performed in a known remote conference system is executed. Therefore, the description regarding the procedure performed by a connection process is abbreviate | omitted.

  By establishing a session with the server device 20, the terminal device 41 is connected to the remote conference identified by the conference ID. That is, the terminal device 41 enters a virtual conference room where a remote conference identified by the conference ID is held. In the terminal device 41, when a session is established with the server device 20, sound data corresponding to the video data captured by the camera 56 and the sound collected by the microphone 57 is transmitted from the communication unit 53 to the server device 20. Sent to. The server device 20 transmits the video data and sound data from the terminal device 41 to the terminal device in which the session is established among the terminal devices 42 and 43. The server device 20 transmits to the terminal device 41 the video data and the sound data from the terminal device with the session established among the terminal devices 42 and 43. In the terminal device 41, when a session is established with the server device 20, the remote conference screen 60 is displayed on the display unit 50. In the terminal device 41, the communication unit 53 receives video data and sound data transmitted from one or both of the terminal devices 42 and 43, which are transmitted via the server device 20 and the session is established. On the remote conference screen 60 displayed on the display unit 50, a captured image 63 corresponding to the received video data is displayed. The speaker 52 outputs a sound corresponding to the received sound data. In the terminal devices 42 and 43, when the video data and the sound data are received from the terminal device 41, the remote conference screen 60 including the captured image 63 corresponding to the video data is displayed, and the sound corresponding to the sound data is displayed. Is output. In FIG. 4, illustrations regarding these processes are omitted.

After executing S11, the CPU 47 determines whether a connection list has been acquired (S13). The connection list is transmitted from the server device 20 and received by the communication unit 53. When the connection list is received by the communication unit 53, the CPU 47 acquires the connection list via the communication unit 53. When the connection list is acquired (S13: Yes), the CPU 47 stores the acquired connection list in the RAM 49 (S15) .

  For example, it is assumed that a session is newly established between the server device 20 and the terminal device 41 in S11 in a state where the session is established between the server device 20 and the terminal device 42. In this case, the connection list shown in the upper part of FIG. 2 is transmitted from the server device 20 and received by the communication unit 53. At this time, the server device 20 also transmits the connection list shown in the upper part of FIG. The CPU 47 acquires the connection list shown in the upper part of FIG. 2 via the communication unit 53 and stores it in the RAM 49. Furthermore, it is assumed that a session is newly established between the server device 20 and the terminal device 43 in a state where the session is established between the server device 20 and the terminal devices 41 and 42. In this case, the connection list shown in the lower part of FIG. 2 is transmitted from the server device 20 and received by the communication unit 53. At this time, the server device 20 also transmits the connection list shown in the lower part of FIG. The CPU 47 acquires the connection list shown in the lower part of FIG. 2 via the communication unit 53 and stores it in the RAM 49. That is, when the connection list is stored in the RAM 49, the stored connection list (see the upper part of FIG. 2) is updated to the newly acquired connection list (see the lower part of FIG. 2). Each time the terminal devices 42 and 43 receive a new connection list, the stored connection list is updated to a new connection list. The following description is based on the premise that a session is established between the server device 20 and the terminal devices 42 and 43.

  If the connection list has not been acquired (S13: No) or after executing S15, the CPU 47 determines whether a sharing start instruction has been acquired (S17). The user operates the operation unit 51 and presses the share button 61 displayed on the remote conference screen 60. When the share button 61 is pressed, the CPU 47 acquires a share start instruction.

  When the sharing start instruction is acquired (S17: Yes), the CPU 47 executes a sharing start process (S19). The sharing start process will be described later. When the sharing start instruction has not been acquired (S17: No) or after executing S19, the CPU 47 determines whether or not material data has been acquired (S21). The terminal device that is the source of the material data acquired in S21 will be described based on the connection list shown in the lower part of FIG. As described above, the terminal device whose role is set to the organizer or the presenter is permitted to transmit the material data, but the terminal device whose role is set to the participant cannot perform this operation. Therefore, the document data is affirmed (see S17: Yes) in the main process executed in the terminal device 42 (S17: Yes), and the terminal device 41 passes through the server device 20 from the terminal device 42 when S19 is executed. (See S35 of FIG. 5 described later) and received by the communication unit 53. The CPU 47 acquires material data through the communication unit 53.

  When the document data is acquired (S21: Yes), the CPU 47 executes a shared response process (S23). The shared response process will be described later. When the document data is not acquired (S21: No) or after executing S23, the CPU 47 determines whether an end instruction is acquired (S25). The user operates the operation unit 51 and presses the end button 62. When the end button 62 is pressed, the CPU 47 acquires an end instruction.

  When the end instruction has not been acquired (S25: No), the CPU 47 returns the process to S13. Thereafter, the CPU 47 repeatedly executes the processes after S13. When the end instruction is acquired (S25: Yes), the CPU 47 ends the main process. In this case, the CPU 47 executes a procedure for disconnecting the session with the server device 20 with the server device 20. The remote conference at the terminal device 41 ends by disconnecting the session.

<Sharing start processing>
The sharing start process executed in S19 of FIG. 4 will be described with reference to FIGS. The CPU 47 having started the sharing start process displays the material designation screen 65 (S31). The CPU 47 outputs an output command for displaying the material designation screen 65 on the remote conference screen 60 to the display unit 50. In the display unit 50, a material designation screen 65 is displayed on the remote conference screen 60 in accordance with the output command. As shown in FIG. 7, the material designation screen 65 includes an OK button 66, a cancel button 67, and an icon image. The OK button 66 is associated with a sharing instruction for designating specific material data from one or a plurality of data that are candidates for material data. The cancel button 67 is associated with a cancel instruction for designating material data. When the cancel button 67 is pressed, the sharing start process ends.

  The icon image is, for example, an image corresponding to data that is a candidate for material data (see FIG. 7). When there is an external storage device different from the storage device 48 accessible by the terminal device 41, the material designation screen 65 may include an image corresponding to the data stored in the external storage device as an icon image. The external storage device may be a storage device on the network 90, for example. The icon image is associated with storage destination information in which the data is stored. In FIG. 7, icon images A, B, and C corresponding to three pieces of data are illustrated as data that are candidates for material data.

  The user operates the operation unit 51 to select one of the icon images A, B, and C. In FIG. 7, the halftone dot pattern attached to the icon image A indicates that the icon image A is in a selected state. For example, when the icon image A is pressed, the material designation screen 65 is in the state shown in FIG. When the OK button 66 is pressed in the state shown in FIG. 7, the material data corresponding to the icon image A is designated as a sharing target. The CPU 47 accesses the storage location of this material data according to the storage location information associated with the designated icon image, and acquires this material data (S33). When the document data is acquired from the external storage device, the CPU 47 acquires the document data via the communication unit 53. The acquired material data is stored in the RAM 49. Subsequently, the CPU 47 transmits the acquired material data (S35). The CPU 47 outputs a document data transmission command to the communication unit 53. The material data is transmitted from the communication unit 53 to the server device 20 in accordance with the transmission command. Further, the material data is transmitted from the server device 20 to the terminal devices 42 and 43. The transmission of the document data is performed for each part of the document data corresponding to the image for one page by dividing the document data in units of pages. As a specification for realizing transmission of such material data, linearized PDF optimized for Web display is exemplified.

  In the embodiment, when the document data is data corresponding to the document image 64 for a plurality of pages, information indicating the number of pages of the document data portion is included in the portion of the document data corresponding to the image of each page. ing. Further, information indicating the last page is included in the part of the material data corresponding to the image of the last page. Even when the document data is data corresponding to the document image 64 of only one page, information indicating the first page and information indicating the last page are included. In S35 of FIG. 5, the part of the material data corresponding to the image on the first page may be transmitted first, and then each part of the material data corresponding to the image on and after the second page may be transmitted sequentially. .

  After executing S35, the CPU 47 determines whether a completion notification has been acquired (S37). The completion notification is a notification indicating that the material data has been acquired by the terminal device that is the transmission destination of the material data. The completion notification is transmitted in S73 of FIG. It is assumed that the material data transmitted from the terminal device 41 in S35 is received by the terminal device 42. In this case, the terminal device 42 transmits a completion notification. It is assumed that the material data transmitted from the terminal device 41 in S35 is received by the terminal device 43. In this case, the terminal device 43 transmits a completion notification. In the terminal device 41, the completion notifications from the terminal devices 42 and 43 are received by the communication unit 53. The CPU 47 acquires a completion notification via the communication unit 53. The completion notification includes the terminal ID of the transmission source terminal device.

  When the completion notification has not been acquired (S37: No), the CPU 47 repeatedly executes S37. When the completion notification is acquired (S37: Yes), the CPU 47 registers the terminal ID included in the acquired completion notification in the completion notification list (S39). For example, when the completion notification from the terminal device 42 is newly acquired in a state where the completion notification from the terminal devices 42 and 43 has not been acquired, the CPU 47 registers the USER 42 in the completion notification list (upper part of FIG. 8). reference). When the completion notification from the terminal device 42 is acquired and the completion notification from the terminal device 43 is not acquired, and the completion notification from the terminal device 43 is newly acquired, the CPU 47 adds the USER 43 to the completion notification list. Is registered (see the lower part of FIG. 8). The completion notification list is stored in the RAM 49. In the embodiment, the completion notification acquired last is referred to as “acquired completion notification”.

  Subsequently, the CPU 47 determines whether or not completion notifications from all the terminal devices have been acquired (S41). In the embodiment described with the terminal device 41 as a main body, it is determined whether or not the completion notifications from the terminal devices 42 and 43 have been acquired. In this determination, the CPU 47 specifies the terminal IDs of the terminal devices 42 and 43 participating in the remote conference from the connection list stored in the RAM 49, and all of them are registered in the completion notification list stored in the RAM 49. Judgment is made. When all the terminal IDs in the connection list are registered in the completion notification list, the determination in S41 is affirmed (S41: Yes). In this case, the CPU 47 proceeds to S57 in FIG.

  On the other hand, when all the terminal IDs in the connection list are not registered in the completion notification list, the determination in S41 is negative (S41: No). In this case, the CPU 47 determines whether the roles of the terminal devices 42 and 43 are the same (S43). When the roles of the terminal devices 42 and 43 are the same (S43: Yes), the CPU 47 shifts the processing to S51 in FIG. If the roles of the terminal devices 42 and 43 are not the same (S43: No, refer to the lower part of FIG. 2), the CPU 47 is an organizer whose role of the terminal device of the terminal ID included in the acquired completion notification is the highest role. Is determined (S45). The CPU 47 makes each determination of S43 and S45 according to the connection list stored in the RAM 49.

  When the role of the terminal device with the terminal ID included in the acquired completion notification is not the organizer (S45: No), the CPU 47 returns the process to S37. Thereafter, the CPU 47 repeatedly executes the processes after S37. When the role of the terminal device of the terminal ID included in the acquired completion notification is the organizer (S45: Yes), the CPU 47 determines whether the role of the terminal device for which the completion notification has not been acquired is the organizer ( S47). In S47, the CPU 47 specifies a terminal ID that is not registered in the completion notification list among the terminal IDs registered in the connection list. The CPU 47 determines whether the role for the specified terminal ID is the organizer from the connection list. When the role of the terminal device for which the completion notification has not been acquired is the organizer (S47: Yes), the CPU 47 returns the process to S37. Thereafter, the CPU 47 repeatedly executes the processes after S37. In addition, when S47 is affirmed (S47: Yes), the completion notification has been obtained from all the organizers.

  When the role of the terminal device for which the completion notification has not been acquired is not the organizer (S47: No), the CPU 47 shifts the processing to S49 in FIG. In S49, the CPU 47 determines whether the groups of the terminal devices 42 and 43 are the same. That is, the CPU 47 determines whether the groups for the terminal IDs of the terminal devices 42 and 43 are the same according to the connection list stored in the RAM 49. When the groups of the terminal devices 42 and 43 are the same (S49: Yes), the CPU 47 moves the process to S57. When the groups of the terminal devices 42 and 43 are not the same (S49: No), the CPU 47 shifts the process to S53.

  In S51, the CPU 47 determines whether the groups of the terminal devices 42 and 43 are the same. This determination is made according to the connection list stored in the RAM 49, as in S49. When the groups of the terminal devices 42 and 43 are not the same (S51: No), the CPU 47 shifts the process to S53. In S53, the CPU 47 determines whether the group of terminal devices with the terminal ID included in the acquired completion notification is different from the group to which the own device belongs (hereinafter referred to as “own group”). That is, according to the connection list stored in the RAM 49, the CPU 47 determines whether the own group for the terminal ID of the own device and the group for the terminal ID included in the acquired completion notification are the same.

  If the group of the terminal device with the terminal ID included in the acquired completion notification is different from the own group (S53: Yes), is there a completion notification that has not been acquired from the terminal device of another group different from the own group? Is determined (S55). In S55, the CPU 47 specifies a terminal ID that is not registered in the completion notification list among the terminal IDs registered in the connection list. The CPU 47 determines whether the group for the identified terminal ID is the same as the own group from the connection list. If there is no completion notification that has not been acquired from another group of terminal devices (S55: No), the CPU 47 shifts the process to S57.

  When the groups of the terminal devices 42 and 43 are the same (S51: Yes), when the terminal device group of the terminal ID included in the acquired completion notification is not different from the own group (S53: No), or a terminal of another group When there is a completion notification that has not been acquired from the apparatus (S55: Yes), the CPU 47 returns the process to S37 of FIG. Thereafter, the CPU 47 repeatedly executes the processes after S37.

  In S57, the CPU 47 displays a material image 64 corresponding to the material data. Note that the material data is acquired in S33 of FIG. 5 and stored in the RAM 49. The CPU 47 outputs an output command for displaying the material image 64 on the remote conference screen 60 to the display unit 50. The display unit 50 displays the material image 64 on the remote conference screen 60 in accordance with the output command (see the lower part of FIG. 3). When the document image 64 is a multi-page image, a specific one-page image is displayed. For example, the image of the first page among the images of a plurality of pages is displayed. After executing S57, the CPU 47 ends the sharing start process.

<Shared response processing>
The shared response process executed in S23 of FIG. 4 will be described with reference to FIG. The shared response process is executed by the terminal device that is the transmission destination of the material data. In the above description, the terminal device 41 is the terminal device that is the source of the material data, and the terminal devices 42 and 43 are the terminal devices that are the destination of the material data. However, in the remote conference by the terminal devices 41, 42, 43, as is clear from the main process shown in FIG. 4, any one of the terminal devices 42, 43 becomes the terminal device that is the source of the material data, In this terminal device, the sharing start process (see FIGS. 5 and 6) may be executed in S19 of FIG. 4 described above. In this case, the terminal device 41 becomes a transmission destination terminal device of the document data, and the terminal device 41 executes a shared response process. In the embodiment, the execution subject of the shared response process will be described as the terminal device 41. In this case, the terminal device that is the source of the material data is the terminal device 42.

  The CPU 47 that has started the shared response process determines whether or not acquisition of material data has started (S61). The material data is transmitted as partial data divided into page units in S35 of FIG. 5 and sequentially received by the communication unit 53. The CPU 47 acquires material data sequentially received by the communication unit 53 via the communication unit 53. The material data is sequentially stored in the RAM 49. When the acquisition of the document data has not started (S61: No), the CPU 47 repeatedly executes S61. When the acquisition of the document data is started (S61: Yes), the CPU 47 determines whether the part of the document data corresponding to the image for one page is acquired (S63). When the part of the material data corresponding to the image for one page has not been acquired (S63: No), the CPU 47 repeatedly executes S63.

  When the material data portion corresponding to the image of one page is acquired (S63: Yes), the CPU 47 has already displayed the first page image of the material image 64 corresponding to the acquired material data portion. It is determined whether there is (S65). For example, when the part of the material data corresponding to the acquired image for one page includes information indicating the first page, the determination in S65 is negative (S65: No). In addition, when the specification is such that the document data is sequentially transmitted from the first page, the portion of the document data corresponding to the acquired image for one page is affirmed for the first time after the sharing response process is started ( If the data is S63 (Yes), the determination in S65 is negative (S65: No). When the determination in S65 is negative (S65: No), S67 described later is an unexecuted state after the shared response process is started. If the determination in S65 is negative (S65: No), the CPU 47 displays the first page image of the document image 64 (S67). The CPU 47 outputs to the display unit 50 an output command for displaying the first page image of the document image 64 on the remote conference screen 60. In the display unit 50, the image of the first page of the document image 64 is displayed on the remote conference screen 60 in accordance with the output command (see the lower part of FIG. 3).

  The description returns to S65, and in the shared response process, when S71 described later is denied (S71: No) and then the process is returned to S63, S67 has already been executed. Therefore, the determination in S65 is affirmed (S65: Yes). In this case, for example, the part of the material data corresponding to the acquired image for one page is data including information indicating a predetermined page after the second page. Further, when the specification is such that the document data is sequentially transmitted from the first page, the part of the document data corresponding to the acquired image for one page is affirmed in S63 after the shared response process is started (S63). : Yes) is the second and subsequent data. When S65 is affirmed (S65: Yes) or after executing S67, the CPU 47 determines whether the page change is set as the authority for the own device (terminal device 41) (S69). In S <b> 69, the CPU 47 determines whether the authority “page change” is set for the terminal ID of the own device in the connection list stored in the RAM 49. When the page change is set as the authority for the own device (S69: Yes), the CPU 47 determines whether the entire document data has been acquired (S71). In S <b> 71, the CPU 47 determines whether the entire document data has been acquired according to the information indicating that it is the last page included in the acquired document data portion. If the entire document data has not been acquired (S71: No), the CPU 47 returns the process to S63. Thereafter, the CPU 47 repeatedly executes the processes after S63. When the document data is data corresponding to the document image 64 of only one page, S71 is not denied (S71: No).

  When the page change is not set as the authority for the own device (S69: No), or when the entire document data is acquired (S71: Yes), the CPU 47 transmits a completion notification (S73). As described above, the completion notification includes the terminal ID of the own apparatus. The CPU 47 outputs a completion notification transmission command to the communication unit 53. In accordance with the transmission command, a completion notification is transmitted from the communication unit 53 to the server device 20. Further, the completion notification is transmitted from the server device 20 to the terminal device 42. Thereafter, the CPU 47 ends the shared response process.

<Effect of embodiment>
According to the embodiment, the following effects can be obtained.

  (1) When the terminal device 41 is the terminal device that is the transmission source of the material data and the terminal devices 42 and 43 are the terminal devices that are the transmission destination of the material data, the terminal device 41 receives a completion notification from the terminal devices 42 and 43. When acquired (see S41 in FIG. 5: Yes), the material image 64 corresponding to the material data is displayed on the remote conference screen 60 displayed on the display unit 50 (see S57 in FIG. 6). However, in the terminal device 41, in S43 to S47 in FIG. 5 and S49 to S55 in FIG. 6, the predetermined conditions specified by the attribute information (role, authority, and group shown in FIG. 2) for the terminal devices 42 and 43 are obeyed. By appropriately executing the determination, the display of the document image 64 on the remote conference screen 60 can be appropriately started.

  For example, when the roles set in the terminal devices 42 and 43 are the same, the terminal devices 41 and 43 are in the same group, and the terminal device 42 is in another group, the terminal device 41 receives a completion notification from the terminal device 43. Even if it is not acquired, the material image 64 can be displayed on the remote conference screen 60 at the timing when the completion notification from the terminal device 42 is acquired (S41: No in FIG. 5, S43: Yes, FIG. 6). (See S51: No, S53: Yes, S55: No, S57). In addition, when the role set in the terminal device 42 is the participant, the role set in the terminal device 43 is the organizer, and the terminal devices 41, 42, and 43 are in the same group, the completion from the terminal device 42 is completed. Even if the notification is not acquired, the material image 64 can be displayed on the remote conference screen 60 at the timing when the completion notification from the terminal device 43 is acquired (S41: No, S43: No, S45 in FIG. 5). : Yes, S47: No, see S49 in FIG. 6: Yes, S57).

  Therefore, in the terminal device 41 which is the source of the material data, the material data transmitted from the own device is acquired by the other terminal devices 42 and 43 participating in the remote conference, and the material image 64 corresponding to this is obtained. It can notify that it is displayed on the terminal devices 42 and 43 (see the lower part of FIG. 3). The user of the terminal device 41 can recognize that the material image 64 is displayed on the terminal devices 42 and 43 in accordance with the display of the material image 64 and can appropriately start explanation using the material image 64. For example, as described above, even if the roles of the terminal devices 42 and 43 are set in correspondence with the remote conference identified by the conference ID, the attribute information is not subordinate to each remote conference. According to the group, the display of the material image 64 on the remote conference screen 60 can be started as appropriate.

  (2) When the terminal device 41 is the terminal device to which the document data is transmitted and the authority to change the page is set in the terminal device 41, the terminal device 41 notifies the completion when the entire document data is acquired. Is transmitted (see S69: Yes, S71: Yes, S73 in FIG. 9). On the other hand, when the terminal device 41 is the terminal device to which the document data is transmitted and the authority to change the page is not set in the terminal device 41, the document image 64 corresponds to the image of the first page even if the document image 64 has a plurality of pages. When the portion of the document data is acquired, a completion notification is transmitted on condition that the page is displayed (see S53: Yes, S67, S69: No, S73 in FIG. 9). Therefore, the completion notification transmission timing can be changed according to the authority. That is, the terminal device 41 can transmit a completion notification at the timing when the document data corresponding to the page of the displayable document image 64 is acquired.

<Modification>
The embodiment can also be performed as follows. Some configurations of the modifications shown below can be appropriately combined and employed. Hereinafter, points different from the above will be described, and description of similar points will be omitted as appropriate.

  (1) The remote conference system 10 is provided with a server device 20 (see FIG. 1). For example, the material data and the completion notification are transmitted and received between the terminal devices 41, 42, and 43 via the server device 20. The remote conference may be performed by the terminal devices 41, 42, and 43 communicating directly via the network 90. In the remote conference system 10 in which such a P2P type remote conference is executed, the server device 20 is omitted.

  (2) In the sharing start process shown in FIGS. 5 and 6, S49, S53, and S55 in FIG. 6 executed after S47 in FIG. 5 is denied (S47: No in FIG. 5) may be omitted. Good. In this case, in S43 after S41 in FIG. 5 is denied (see S41: No in FIG. 5), the role of the two terminal devices that are the transmission destinations of the material data among the terminal devices 41, 42, and 43 is It is determined whether they are the same. Even if the roles of the two terminal devices described above are not the same (see S43: No in FIG. 5), a completion notification is obtained from the terminal device whose role is set as the organizer in S45 and S47. If it is determined that the process is performed (see S45: Yes, S47: No in FIG. 5), the process may be shifted to S57 in FIG. 6 to display the material image 64 (lower row in FIG. 3). reference).

  In addition, in the sharing start process, S43 to S47 in FIG. 5 and S49 in FIG. 6 may be omitted. In this case, if S41 in FIG. 5 is negative (see S41 in FIG. 5: No), the process proceeds to S51 in FIG. 6 and is the transmission destination of the material data among the terminal devices 41, 42, and 43. It is determined whether the groups of the two terminal devices are the same. Even if the group of the two terminal devices described above is not the same (see S51: No in FIG. 6), in S53 and S55, the group of the group different from the own device (the terminal device that transmitted the document data) is different. If it is determined that a completion notification from the terminal device has been acquired (see S53: Yes, S55: No in FIG. 6), the document image 64 may be displayed in S57 in FIG. (See the lower part of FIG. 3).

  (3) In the sharing start process shown in FIGS. 5 and 6, the role that is the determination condition in S45 and S47 in FIG. 5 is the organizer that is the highest role set in the remote conference. The determination conditions in S45 and S47 may be the highest role among the roles of the terminal device that is the transmission destination of the material data. For example, it is assumed that the terminal devices that are the destinations of the material data are the terminal devices 42 and 43, the role of the terminal device 42 is the presenter, and the role of the terminal device 43 is the participant (see the lower part of FIG. 2). In this case, S45 and S47 are determined on the condition of the presenter who has a higher role among the presenters and participants. That is, when the terminal ID included in the acquisition completion notification is USER42, S45 is affirmed (see S45: Yes in FIG. 5), while S47 is negated (see S47: No in FIG. 5). On the other hand, when the terminal ID included in the acquired completion notification is USER43, S45 is negative (see S45: No in FIG. 5). In this case, S47 is not executed. However, if S47 is executed, S47 is affirmed (see S47: Yes in FIG. 5).

  Furthermore, the role set in the remote conference is set to three, the organizer, the presenter, and the participant. When there are three or more roles, a plurality of roles may be used as determination conditions in S45 and S47 in FIG. Based on the above, for example, the determination conditions in S45 and S47 may be the organizer or the presenter. In this case, in S45, it is determined whether the role for the terminal ID included in the acquired completion notification is the organizer or the presenter. When the role for the terminal ID included in the acquired completion notification is the organizer or the presenter, S45 is affirmed (see S45 in FIG. 5: Yes). If the role for the terminal ID included in the acquired completion notification is a participant, S45 is denied (see S45: No in FIG. 5). In S47, it is determined whether the role of the terminal device for which the completion notification has not been acquired is the organizer or the presenter. If the role of the terminal device for which the completion notification has not been acquired is the organizer or the presenter, S47 is affirmed (see S47: Yes in FIG. 5). If the role of the terminal device for which the completion notification has not been acquired is a participant, S47 is denied (see S47: No in FIG. 5).

  (4) In the sharing start process shown in FIGS. 5 and 6, the material image 64 is displayed on the remote conference screen 60 being displayed on the display unit 50 in S57 of FIG. In S57, for example, a message such as “Ready to start remote conference” may be output from the speaker 52. The user of the terminal device that is the transmission source of the document data can appropriately start the explanation using the document image 64 according to the output of this message. In addition, in S57 of FIG. 6, a predetermined portion of the terminal device may be caused to emit light or be lit.

(5) In the shared response process shown in FIG. 9, when it is determined in S63 that the portion of the document data corresponding to the image for one page has been acquired (S63: Refer to Yes in FIG. 9), the document image 64 is updated in S67. It is determined whether the first page image has been displayed. The document image 64 may be a plurality of pages. In such a case, the material data may include initial page information indicating the initial display page, and it may be determined whether a portion of the material data corresponding to the image of the page indicated by the initial page information has been acquired. In this case, S65 and S67 in FIG. 9 are executed for the image of the page indicated by the initial page information. In S33 of the sharing start process shown in FIGS. 5 and 6, the CPU 47 adds initial page information to the acquired material data. The initial page information is set as follows, for example. That is, in S33, it is analyzed whether the acquired material data is data corresponding to the material image 64 including a plurality of pages of images. As a result of the analysis, when the document data is data corresponding to the document image 64 including a plurality of pages of images, the CPU 47 displays an input screen for accepting initial display page settings on the remote conference screen 60. The user operates the operation unit 51 to input an initial display page value. The CPU 47 acquires the input display page value and adds it to the material data as initial page information. For example, the initial page information is transmitted first after transmission of the material data is started. In addition, the initial page information may be included in the part of the material data corresponding to the image of the initial display page.
