Description

Multipoint Video Conferencing System via Multipoint Video Conferencing Terminal

The present invention relates to a system for providing multi-point video conferencing through a point-to-point video conferencing terminal on a packet network, and in particular, to a multi-point through a single point video conferencing terminal capable of supporting a multi-point video conferencing in one system. A video conferencing system.

In general, a video conferencing system refers to a system that supports video and voice communication between users through each terminal. Recently, a video conferencing system uses a public video or packet network, and a video conferencing system using a PC or a terminal composed of independent hardware. There are many systems that support video conferencing.

Currently, ITU-T specifies H.324 as the videoconferencing terminal specification for public networks and H.323 as the videoconferencing terminal specification using packet networks.

However, most of these terminals are capable of only point-to-point communication through calls to destination points, and do not support multipoint video conferencing where multiple participants simultaneously participate in one conference.

Therefore, multiple users cannot make video conferencing with the other party and video and voice in one meeting space, and in order to have a meeting with multiple participants, it is necessary to repeatedly connect and disconnect with each participant of one-to-one communication. A meeting should be conducted.

1 illustrates a case in which four participants (A, B, B, C) have a meeting of all paths for communicating their respective intentions by using the multi-point terminal. This is the same as the diagonal number of polygons whose numbers are vertices, and this is also limited to the assumption that they do not communicate repeatedly.

However, in the related art as described above, when a plurality of users have a meeting in one meeting space using a multi-point terminal, there is a problem that video conferencing with a meeting partner through video and voice cannot be made in one space.

Accordingly, an object of the present invention is to provide a multi-point video conferencing system through a multi-point video conferencing terminal that supports multi-point video conferencing through a multi-point video conferencing terminal.

Another object of the present invention is to provide a multi-point video conferencing system through a multi-point video conferencing terminal to support multiple video conferencing in one system for managing multi-point video conferencing.

And a common mode regulator 204 to determine.

In addition, as shown in FIG. 10, the video conferencing integrated manager 300 includes a message interpreter 301 for interpreting a message requested through the user interface unit 700, and a user meeting through the message interpreter 301. If you want to create or destroy a conference, create a conference creation manager 302 that generates the conference creation mode and conference destruction mode, and an appropriate conference mode for the video or audio mode to be used in the conference generated by the conference creation manager 302. Or a conference mode adjuster 303 that refuses to create a conference for an inappropriate or inappropriate conference mode, and a channel resource adjuster 304 that adjusts a large number of network resources required during a multipoint video conference.

Referring to the operation and effect of the present invention configured as described in detail as follows.

In FIG. 4, the multi-point video conferencing manager 100 is an object created when a conference is created and a participant is connected to the conference, and is created for each participant and performs a procedure for the participant to participate in the conference.

At this time, the multi-point video conference manager 100 processes the service requested by the multi-point video conference manager 200 through interworking with the H.245 signaling entity through the multi-point video conference manager interface 400.

Here, the signaling entity is a place for exchanging messages when exchanging a message with a remote multi-point video conferencing terminal, which is a lower layer of the multi-point video conferencing manager 100, as shown in FIG.

Then, the detailed operation of the multi-point video conference manager 100 will be described with reference to FIG. 6. For example, a service request may be entered or multi-point received from the multi-point video conference manager 200 through the multi-point video conference manager interface 500. Interpret the response to the service requested by the signaling entity 800 in the videoconferencing manager 200 and transmit the message directly to the signaling entity 800 through the multi-point videoconferencing manager interface 400 or transmit it to the state manager 102. do.

Accordingly, the state manager 102 receives a message interpreted through the message interpreter 101 and manages signal management, timer management, channel coding method, channel selection, and the like.

If such information is provided to the channel mode adjuster 103 for channel coding, channel selection, etc. in order to select the corresponding channel, the channel mode adjuster 103 is required for video conferencing when connected to a state terminal. Determine the most suitable mode of video and audio.

The channel connection manager 104 performs a task of setting the most suitable channel between terminals using the channel mode determined by the channel mode controller 103.

A series of service processing processes of the multi-point video conferencing manager 100 that performs the above operation will be described with reference to FIGS. 11 and 12 as follows.

In FIG. 11, when the participant connection is confirmed through the message interpreter 101, the multipoint video conferencing manager 100 determines a channel coding method (Terminal Capability set) (S11), information for determining a master slave relationship (Master Slave Determination) ( S12) is exchanged with the counterpart video conferencing manager.

When the channel coding method is determined by the information exchange as described above (S13), and when the master or slave relationship is determined (S14), the channel mode adjuster 103 determines the most suitable channel among the channel modes (S15), and If either master relationship is not determined, it is in a waiting state.

If the most suitable channel determination is confirmed in the above channel mode (S16), the channel connection manager 104 performs a function of setting a channel necessary for transmitting the image or audio data using the determined channel mode.

In addition, when the end point connection connection is confirmed through the message interpreter 101, the multi-point video conference manager 100 checks whether there is a channel currently open (S121).

If there is a channel currently open as a result of the test, all the open channels are closed (S122).

If a message request (S124) is received from a higher or lower point, a corresponding message is transmitted (S125), and if it is confirmed that all channels are closed (S123), an upper (multipoint video conference manager) or lower (single point video conference terminal). In step S126, a message indicating that the operation is terminated is transmitted, and the process ends (S127).

As described above, the multi-point video conferencing manager 100 determines a channel coding method, sets a slave relationship, and determines a channel mode by transmitting and receiving information with a terminal of a partner when participants for video conferencing are connected. Performs an operation of transmitting image or audio data using a channel.

7, the multi-point video conference manager 200 transmits / receives information to and from the upper layer through the video conference integrated manager interface 600, and the multi-layer video conference manager interface unit as shown in FIG. 7. 500) information is transmitted and received.

In this case, the multi-point video conference manager 100 is connected to the multi-point video conference manager 200 through the multi-point video conference manager interface 500. The multi-point video conference manager 100 participates in the current conference. Since there are as many participants as possible, it can be seen that a plurality of multi-point video conference managers are connected to one multi-point video conference manager through the multi-point video conference manager interface 600.

That is, referring to FIG. 3, a plurality of multi-point video conference managers are connected to one multi-point video conference manager, and a plurality of multi-point video conference managers are connected to and managed by one video conference integrated manager.

Then, referring to FIG. 8, the multi-point video conferencing manager 200 includes a message from the video conferencing manager 300 and the multi-point video conferencing manager interface 500. When a message from the multi-point video conferencing manager 100 is input through the message, the message interpreter 201 interprets the message to the state manager 202 or immediately transfers the interface unit 500 or 600 according to the message. It transmits to the only point video conference manager 100 or the video conference integrated manager 300.

Accordingly, the state manager 202 transmits the message requested by the message interpreter 201 through the multi-point and multi-point video conferencing manager interface 500 and 600 to the multi-point video conference manager 100 or the video conference. It transmits to the integrated manager 300, or performs a function module appropriate to the current state for the message interpreted from the message interpreter 201.

The participant connection manager 203 then functions to process the multi-point video conference manager that is created and destroyed when a new participant joins or leaves the conference.

In addition, the common mode coordinator 204 performs a function of determining a common mode of a channel required for the entire conference with a channel coding method (Capability set) delivered from a plurality of participants.

A series of service processing processes of the multi-point video conferencing manager 200 which performs the above operation will be described with reference to FIGS. 13 and 14 as follows.

In FIG. 13, when the multi-point video conference manager 200 receives a message to generate a single-point video conference manager from the video conference integrated manager 300 through the message interpreter 201 in FIG. Create a video conference manager (S132).

Checking whether or not the successful creation of the single point video conferencing manager (S133) is successful, informing the video conferencing integrated manager 300 of the successful creation of the manager through the video conferencing integrated manager interface unit 600, and failing to generate the manager. Inform.

When the multipoint video conference manager 200 receives a message to destroy the single point video conference manager from the video conference integrated manager 300 (S134), the multipoint video conference manager 200 checks whether there is a single point video conference manager. (S135)

As a result of the inspection, if there is a multi-point video conferencing manager present, the existing manager is destroyed.

And if there are any requirements in common mode (S136) by connecting to the common mode regulator 204 to listen to the desired requirements.

In addition, in FIG. 14, when the message for destroying the multi-point video conference manager is input through the message interpreter 101 (S141), the multi-point video conference manager 200 determines whether one or more multi-point video conference managers exist. (S142)

As a result, if there is an existing manager, a message for destroying all existing multi-point video conference managers is output to the single-point video conference manager (S143), and if there is no existing multi-point video conference manager, the multi-point video conference manager Destroy all of them and notify the destroyed person to the integrated video conference manager (S144).

When the participant related message is transmitted from the multi-point video conference manager 100 (S145), the participant connection manager 203 is connected.

If other requirements are requested (S146), the service path is interpreted and the corresponding service request is made at multiple points or only points.

9 is a video conferencing integrated manager 300 between a user interface unit 700, which is an initial user service access point, and a video conferencing integrated manager interface 600, for interfacing with a lower-level multi-point video conferencing manager 200. FIG. Is a view showing that is located.

One video conference integrated manager 300 exists while the system is running, and a multipoint video conference manager 200 is generated for each conference, and a plurality of multipoint video conference managers are connected.

Then, the detailed operation of the videoconferencing integrated manager 300 will be described based on FIG. 10. For example, the message interpreter 301 may request a service through the user interface 700 or the videoconferencing integrated manager interface 600. The meeting creation manager 302 provides a service for generating a message for a request for creating a meeting or destroying a meeting for a meeting destruction message through the user interface 700. .

The conference creation manager 302 selects an appropriate mode for a video or audio mode to be used in a conference created by a user.

In addition, the conference creation manager 302 provides a service through interaction with the conference mode adjuster 303. The conference mode adjuster 303 selects an appropriate mode for a video or audio mode to be used in a conference created by a user. It performs the function of selecting and rejects the creation of conference for inappropriate conference mode.

In addition, the channel resource coordinator 304 performs coordination of many network resources required during the performance of multiple multipoint video conferencing, which allows the lower layer to request network resources to determine the channel mode and open the channel. In this case, an arbitration function is performed to prevent collision of multiple channel resources to be used.

A series of service processes of the videoconferencing integrated manager 300 performing such an operation will be described with reference to FIGS. 15 and 16 as follows.

In the video conferencing manager 300, when a message to create a meeting is input through the message interpreter 301 (S151), the video conferencing manager 300 checks whether the meeting already exists (S152).

If the same meeting already exists, meeting creation fails. If the same meeting does not exist, the conference mode coordinator 303 checks whether the information transmitted in the process of creating a meeting is valid for creating the meeting. (S153)

If the conference mode adjuster 303 cannot determine the conference mode, the conference creation fails, and the result of the failure is known to the user (S154).

When the same conference does not exist and the conference mode adjustment does not fail in the conference mode adjuster 303, a multi-point video conference manager is generated, and the generated multi-point video conference manager has a unique conference identifier. This conference identifier distinguishes it from other conferences.

In this way, if the generation of the multi-point video conference manager succeeds, the user interface unit 700 informs the user of this.

When a message indicating the end of the conference is input (S156), it is checked whether a conference that currently exists exists (S157).

As a result of the inspection, if there is no meeting, there is no meeting, so the user is notified of the failure to terminate the meeting, and if there is a meeting, a destruction request is made to the multi-point video conference manager.

In addition, when other requirements are input (S158), first, the module performing the service is checked whether the integrated video conferencing manager. If the service subject is the integrated video conferencing manager, the service is processed. Transparent to the meeting manager.

In addition, when the video conferencing integrated manager 300 receives a request for initialization during operation of the system through the message interpreter 201 from the user (S161), the video conference integrated manager 300 sets an interface with the user interface unit 700. Perform the required initialization process.

Notify the user when the initialization process is complete.

In addition, if a message is input from the user to terminate (S162), a rather complicated procedure is performed. First, it is checked whether or not there is an existing meeting.

As a result of the check, if the meeting does not exist, a message is sent to the user indicating that the system can be terminated (S164). If there is a meeting in progress, all multipoint video conference managers are requested to terminate the meeting (S165).

At this time, if the user requests the end of the meeting (S166), at the end of each meeting, the multipoint video conference manager receives a message indicating that the meeting has ended. If there is still a meeting to be terminated, the user must continue to wait. When the final meeting end message is received, the end of the video conference integrated manager is sent to the user that the system may be shut down.

By the operation as described above, a multi-point video conference is supported by using a terminal supporting a single point-to-point video conference on a packet network.

Therefore, the present invention has the effect of supporting multiple multipoint video conferences in one system.
