Description

  The present invention relates to a multipoint communication conference apparatus, a control method thereof, and a multipoint communication conference system, and in particular, multipoints for displaying and sharing conference data, video conference video, and other shared data that can be shared among multiple sites. The present invention relates to a teleconferencing device.

  Instead of the conventional TV conference system that uses only audio and video images, a multipoint communication conference system that shares various shared data, including digitalized conference materials and whiteboards, between multiple locations will be used. It is becoming.

  In such a multipoint communication conferencing system, shared data that can be referred to during the conference is enriched, while users participating in the conference check the flow of the conference as to which shared data is the center of the agenda. It is necessary to identify. In particular, when participating in a conference halfway, in order to identify shared data to be referred to, the conference flow must be stopped and other participants must be inquired about the conference flow and the shared data being referenced. For this reason, in a conference in which the number of participants increases sequentially, a lot of conference time is taken to follow such midway participants.

  In order to solve such a problem of the midway participant, a technique has been proposed in which the midway participant grasps the content of the conference in a short time without interrupting the conference (for example, Patent Documents 1, 2, and 3). reference).

In Patent Document 1, conference data such as audio and images captured by a camera is recorded and distributed to participants on the way.
In Patent Document 2, a history of shared data or the like during a meeting is recorded, a summary of the meeting is created and distributed to participants on the way.
Further, in Patent Document 3, a shortened video is created from video recorded by synthesizing voices and images of each terminal and shown to participants on the way. The abbreviated video is continuously updated, and when the time of the abbreviated video reaches a real time, the video to be shown to the participants on the way is switched to the real time video. In this way, the midway participants can smoothly participate in the discussion because they can refer to the video referred to by the existing participants smoothly after confirming the transition of the conference.

  In these Patent Documents 1 to 3, since the midway participant can check the flow of the conference without interrupting the progress of the conference, the existing participants who have already joined the conference without worrying about the status of the midway participant Can proceed.

JP-A-10-322684 JP 2003-339033 A JP 2001-128133 A

  However, Patent Document 1 and Patent Document 2 do not describe support for midway participants after understanding the flow of the conference. In an actual meeting, it takes some time for participants on the way to confirm the flow of the meeting. During that time, the conference progresses, so mid-way participants cannot immediately know what shared data they are currently discussing, even if they want to participate in the discussion.

  In Patent Document 3, the video to be shown on each terminal, which is a support method for smoothly participating in discussion after understanding the flow of the conference, is displayed on a single screen by reducing all images of other bases except for one's own base. The case is assumed to be stored and displayed. In that case, when a plurality of terminals are participating in the conference, an image displayed by each terminal is reduced. Although it is sufficient that the number of shared data displayed on each terminal is about one, it is not effective in a meeting in which a plurality of shared data is shared and discussed between terminals. Even in that case, if the display state of the shared data between the bases is synchronized, it is only necessary to show the display state of a certain base, but if the display state of the shared data is not synchronized between the bases, join in the middle It is necessary to show the display state of all bases to the person. In this state, it is difficult for the midway participants to identify the shared data currently being discussed.

Further, as a common problem of Patent Documents 1 to 3, it is necessary for the participant to identify the shared data used in the discussion and display it on the screen. For this reason, there was a problem that the timing of joining the discussion was further delayed.
In view of the above-described problems, an object of the present invention is to automatically display shared data, which is currently the center of discussion, on a midway participant's screen without interrupting the flow of discussion.

  The multipoint communication conferencing apparatus of the present invention manages a plurality of client terminals participating in a multipoint communication conference, and includes any one of materials, video, audio, and an electronic whiteboard used by the plurality of client terminals for the conference A multipoint communication conferencing apparatus for sharing data and displaying the shared data on the client terminal, and a degree-of-interest counting means for counting the handling status of the shared data in the client terminal, and a layout prioritized in advance Information and a shared data arrangement means for determining and arranging the arrangement order of shared data according to the order of the attention levels calculated by the attention level aggregation means, and a multipoint communication conference held between the plurality of client terminals. Placement result notification for notifying the result of placement by the shared data placement means to the client terminal that joins midway Characterized in that it comprises a stage.

  According to the present invention, it is possible to automatically display shared data, which is currently the center of discussion, on the midway participant's screen without interrupting the flow of discussion.

FIG. 8 is a flowchart showing the processing procedure of the conference server 111 when joining the conference client halfway according to the first embodiment.
First, in step S <b> 801, the control unit 201 acquires a shared data list of the current conference managed on the storage unit 202. In step S802, the display state of each shared data in each conference client participating in the conference is acquired via the network I / F unit 205.

In step S <b> 803, the control unit 201 reads (refers to) an evaluation value for each display state of the shared data from a setting file stored in the storage unit 202 in advance. Subsequently, an evaluation value is calculated from the display state information of each shared data acquired in S802, and the degree of attention is ranked.
In step S <b> 804, the control unit 201 reads (refers to) layout information in which an arrangement position is specified for each order of interest from a setting file stored in the storage unit 202 in advance. Then, shared data placement processing is performed in which the shared data is allocated to the layout information in the order of attention in S804. Through the processing in S804, the material that is drawing attention in the conference is preferentially laid out.

  Finally, in step S805, the control unit 201 notifies the conference client participating in the middle of the layout information of the arrangement result assigned the display position of the shared data in step S804 via the network I / F unit 205. Process.

  As described above, according to the first embodiment, when a conference client joins a conference halfway, the material currently attracting attention at the conference is displayed on the midway conference client. The person can immediately refer to the materials necessary for the discussion. Further, in this series of processes, there is no influence on the monitoring of other conference clients participating in the conference, and the ongoing conference is not disturbed.

In the first embodiment, a case where one piece of shared data is displayed in one window is described as an example, but the present invention is not limited to this. For example, any window display method may be used, such as when one shared data is displayed in a plurality of windows. The evaluation table may be changed to correspond to various window display methods.
Also, another rule may be applied to a part of the shared data, such as “The minutes are always displayed in the third layout”, “Video conference is evaluated as having the highest attention”, etc. Add exception rule storage function to store rules. Then, an arbitrary arrangement order may be assigned to specific shared data in accordance with the exception rule for the display of the conference client participating in the middle.

<Embodiment 2>
In the second embodiment, shared data that is attracting attention in the discussion is identified from a plurality of evaluation tables (evaluation guidelines), the material that is accurately attracted attention is determined from various judgment materials regarding the conference, It can be reflected in the layout.
In this case, the user sets a plurality of evaluation tables for the setting file in advance. Here, an example of the evaluation table is shown in FIGS.

  In the evaluation table shown in FIG. 9, an evaluation rule is defined based on a focus state for a window displaying shared data. The focused window is given 5 points as being noticed, and 0 points are given to other windows.

  In the evaluation table shown in FIG. 10, an evaluation rule based on the display size of the window is defined based on a standard different from that of the first embodiment. If the area of the window occupies more than half of the area of the display screen, 5 points are given, and if it is more than 1/4, 2 points are given. On the other hand, for the shared data whose window is not displayed, -3 points are given as not being noticed.

  In the evaluation table shown in FIG. 11, an evaluation rule is defined based on the display position of the window displaying the shared data. The window displayed in the center of the screen is given 2 points as being noticed, while the window that is greatly protruding from the screen is given -3 points as being not noticed.

  FIG. 12 shows a display state of the conference client 124 before joining midway in the second embodiment. The conference clients 121 to 123 are participating in the conference and displaying a part of the shared data. The shared data used for the conference is the same as in the first embodiment, and each conference client can freely change the display layout of the shared data as in the first embodiment.

  In FIG. 12, the conference client 121 displays “document 1.txt” in a window 1201 of a third size of the screen. Note that the window 1201 is displayed so as to partially protrude from the display area of the screen. In addition, a “video conference” window 1202 and a “minutes” window 1203 are each displayed at a size one fifth of the screen. In the conference client 121, the “video conference” window 1202 is focused. Similarly, the conference clients 122 and 123 also lay out the shared data window in a layout / focus state that is partially different from that of the first embodiment.

  FIG. 13 is a diagram illustrating the attention level totaling result in which the conference server 111 totals the attention level of each shared data according to the evaluation tables of FIGS. 9 to 11 and calculates the attention level ranking. Information of each conference client 121 to 123 is collected for each evaluation item of the focus, size, and position of the window, and the total value thereof is used as the degree of attention. The focus is applied to the conference clients 121 and 123, and the degree of attention of the “video conference” displayed in the forefront is high, and the degree of attention rank is determined to be first.

When the conference server 111 determines the layout based on the attention rank, the conference server 111 transmits the layout information to the conference client 124 that participates midway as in the first embodiment. The result of displaying the shared data based on the layout information received by the conference client 124 is shown in FIG. A “video conference” window 1401 that has been evaluated with the highest degree of attention is displayed in the largest size.
Hereinafter, specific processing contents of the conference server 111 according to the second embodiment will be described with reference to the flowchart of FIG. 15.

FIG. 15 is a flowchart illustrating a processing procedure of the conference server 111 when joining the conference client halfway according to the second embodiment. The processing steps common to the first embodiment are given the same step numbers as in FIG.
First, the control unit 201 acquires the display state of the shared data in each conference client in step S801 as in the first embodiment. Thereafter, S1501 to S1503 are repeated to obtain evaluation values for all the evaluation items, and the shared data attention level is totalized to be totaled in the attention level totalization chart.

  In step S1501, the control unit 201 reads (refers to) one of the evaluation tables that has not been evaluated, and enters the evaluation result in step S1502. Next, in S1503, the presence / absence of an unevaluated evaluation table is confirmed. If there is an unevaluated table, the process returns to step S1501 and the evaluation is continued using the remaining evaluation table. When all the evaluations are completed, the attention ranking is determined, the layout is performed, and the layout result is notified to the halfway participating conference client in S804 and S805 as in the first embodiment.

  As described above, according to the second embodiment, by using a plurality of evaluation tables, it is possible to automatically select a material that is attracting attention from various judgment materials related to a meeting with high accuracy.

  When the conference server 111 has a layout synchronization function for synchronizing the display layouts of the conference clients participating in the conference, the same layout may be used for the conference clients that joined midway. Thereby, the display layout of shared data can be synchronized among a plurality of clients. Therefore, if the conference server 111 has the 4-part layout of FIG. 16 and the list display layout of FIG. 17 in addition to the basic layout of FIG. 6, and the 4-part layout was performed before participation in the conference client 124, the display at that time is shown in FIG. 18 and so on. After that, when each conference client 121 to 123 changes the layout, and then performs the conference client participation process of the second embodiment, the display of the conference client 124 in midway participation is divided into four as shown in FIG. .

It also has a layout acquisition function that acquires the current layout from one of the conference clients displaying the client displaying the shared data with the highest degree of attention. May be adopted.
In this way, it is also possible for the conference clients participating in the middle to arrange the materials according to the latest layout and display the materials with a high degree of attention.

<Embodiment 3>
In the third embodiment, a configuration for determining the degree of attention using evaluation items other than the evaluation table will be described.
In the third embodiment, the conference server 111 extracts the file name of the shared data from the range of the latest 5 minutes of the minutes created during the conference, and counts the number of utterances.
FIG. 20 is a diagram illustrating the attention level aggregation in which the count number and the attention level ranking determined based on the count number are recorded. Since the keyword of “Product A” is the largest, the ranking of the degree of attention is determined to be the first.

As described above, according to the third embodiment, it is possible to infer shared data that is attracting attention using an evaluation value other than the evaluation table and display it on a conference client that participates midway.
Note that the attention level calculation method in the third embodiment can be combined with the calculation method using the evaluation table in the first and second embodiments. It is also possible to recognize not only the minutes but also voice data in a video conference and extract keywords related to the conference data from the voice data in which the speech of the conference is recorded.

<Embodiment 4>
In the fourth embodiment, the degree of attention is determined by using information on the remark status of each conference client, thereby improving the identification accuracy of shared data related to the discussion.
In the fourth embodiment, the conference server 111 monitors the transmission status of the audio data of the video conference, and identifies the conference client who is speaking in the discussion. Thereafter, the evaluation value of the corresponding client in the attention degree totalization chart generated in the first and second embodiments is calculated three times.

In the first embodiment, if it is determined that the conference client 123 is speaking while displaying the “meeting” window in the largest size, the values in the column of the client 123 in the attention level totalization diagram of FIG. . As a result, the degree of attention of the “minutes” is 19 points and the degree of attention ranks first. The conference server 111 determines that the conference client 123 is speaking about the minutes, and the “meeting” is displayed at the most visible position on the conference client 124 participating in the middle.
The information on the conference client that is speaking may be used in addition to the above, and the display layout of the conference client that is participating midway may be synchronized with the conference client that is currently speaking.
