Then, the multi-party video
According to such conventional general multi-party video conferencing system, the multi-party conferencing server unit combines the video of the talker participating in the video conferencing and transmits it to each video conferencing terminal unit.
Therefore, the traffic generated in the multi-party video conferencing system is significant, which may cause a problem of speed degradation, and consequently the quality of the multi-party video conferencing service can not be guaranteed. Particularly, as the number of talkers participating in a video conference increases, the amount of traffic increases exponentially, which results in a problem that a substantial teleconferencing service can not be provided.
The virtualization service that can be applied to the video conferencing service system has recently become more important in the security of internal business secrets and customer information in corporations and research institutes, and it takes a lot of time and manpower for centralized PC management The need for efficient use and management through the computer environment is growing, so it is a technology field in which research has been concentrated.
On the other hand, as cloud system construction becomes more active, device redirection related technologies for sharing end-user devices (for example, video cameras, etc.) other than sharing server resources are increasingly being developed. In a cloud environment that provides virtualization technology, virtualization servers organically connect many devices, exchange data with each other, and provide services.
However, the conventional device redirection technology has a problem that the speed is lowered because a device such as a video camera is executed through the client terminal.
For example, the USB driver may not be able to be executed or the version may be low depending on the USB driver, which may cause a connection speed problem. In addition, in the existing system, even if the USB is the upper version, since it is executed through the client terminal and remotely shared, the program has to be executed at the lowest version speed, and as a result, the execution speed is lowered.
Conventionally, not only device resources such as a video camera are shared between a client terminal and a virtualization server, but device resources executed through the client terminal are shared between client terminals, thereby increasing unnecessary consumption of network resources due to increased traffic.

In addition, the present invention is not limited to sharing video camera resources executed by a client terminal with client terminals, but may share video camera resources between a client terminal and a virtualization server, and configure a virtualization server to execute video camera resources, And to provide a virtualization-based remote video conferencing providing system capable of providing a virtualization-based remote video conferencing service without increasing the number of users.
According to another aspect of the present invention, there is provided a system for providing virtualization-based teleconferencing, the system comprising: a plurality of client terminals operated by video conference participants; And a virtualization server for providing a virtualized video conferencing service to the connected client terminals, wherein the client terminal is connected to the virtualization server, And a client agent for confirming the sharing of the image camera to the virtualization server when a connection of the camera is detected, wherein the virtualization server comprises: a virtualization server which is connected to the client terminals selected as the video conference grouping terminal among the plurality of client terminals, burn Take resources from the camera is characterized in that it comprises a server agent that is controlled to run in a virtual machine.
Here, the client agent may include a connection detection / sharing confirmation module that detects whether the image camera is connected to the client terminal and confirms whether the image camera is shared with the server agent when a connection is detected, A video camera information providing module for transmitting the video camera information to the server agent, and a resource conversion / transmission module for converting resources of the video camera and transmitting the converted video camera information to the server agent.
Here, the server agent selects a connection mode based on the virtual camera designation module for designating a virtual machine and the image camera information transmitted from the image camera information providing module, and connects to client terminals selected as the video conference grouping terminal And a connection control module for executing a video camera connected to the client terminals selected as the video conference grouping terminal in the virtual machine by using the video camera resources transmitted by requesting resource sharing to the video camera .
Here, the client terminals selected as the video conference grouping terminal may be client terminals grouped in advance and stored and managed in the server agent, or client terminals selected by a specific client terminal in a plurality of client terminal lists stored and managed by the server agent Or client group terminals selected by a specific client terminal in a plurality of client terminal group lists stored in the server agent.
According to the virtualization-based remote video conference providing system of the present invention having the above-described technical problem and the solution, when configuring a remote video conference system, a video camera connected to client terminals is shared through a remote virtualization server, The virtualization server is connected to the client terminal to acquire the video camera resource and configure it to be executed through the virtual machine so that it is possible to share the video camera resource between the client terminals and the virtualization server without slowing down or increasing the traffic, There is an advantage that a multi-party video conferencing service can be provided in a guaranteed state.
In addition, since the image camera resources executed through the client terminal are not shared between the client terminals but the image camera resources are shared between the client terminal and the virtualization server, and the image camera resources are executed in the virtualization server, It is possible to provide a virtual teleconference-based teleconferencing service without increasing traffic.

The protocol method is a method of confirming the acknowledgment (ACK) information which confirms whether the data sent to the receiving side arrives sequentially from the beginning to the end and whether the transmitted data has arrived properly to the other party. It has high accuracy and stability, There is a problem that the speed is lowered or a delay occurs.
On the other hand, since there is no process of confirming whether the transmitted data has arrived normally, the socket method has an advantage that it can be transmitted at a high transmission rate, but data loss may occur. However, if the version of the camera is high, it needs to cope with the high speed, so it is reasonable to select the socket type with a high transmission speed.
Accordingly, since the virtual machine of the virtualization server can take and use the image camera resource transmitted from the client terminal by appropriately selecting and controlling the protocol method and the socket method by the
Since the conventional device sharing mechanism is a method of controlling execution in a virtual machine to which a hypervisor of a virtualization server is connected when a client terminal is connected to a device, access control according to the state of the device is not possible. There is a problem that the speed is set to a lower version.
In addition, since the client terminal connects to the virtualization server and the device is executed in the virtual machine, there is a problem that the execution speed of the client terminal is low as well as execution error when the specification of the client terminal is low.
However, the virtualization-based remote video conference providing method according to the present invention does not require the client terminal to access the virtualization server and share resources to execute it, but conversely, the client terminal becomes the server and the server agent of the virtualization server controls the connection and transmission It is possible to perform the flexible connection control according to the state of the image camera and thus to execute the state without lowering the speed of the image camera and the execution can be controlled according to the specification of the virtual machine irrespective of the specification of the client terminal .
Meanwhile, as described above, the
Wherein the connection control module requests the resource sharing of the video camera connected to the client terminals selected as the video conference grouping terminal only when the client terminal corresponds to the client terminals selected as the video conference grouping terminal do.
The client terminals selected as the video conference grouping terminal may correspond to some or all of the client terminal lists stored and managed in the terminal
The client terminals GD selected as the video conference grouping terminal are client terminals grouped in advance and stored and managed in the server agent (refer to FIG. 4A) or stored in the server agent 31 A plurality of client terminal groups G1, G2, ..., Gn, which are client terminals selected by a specific client terminal in a plurality of client terminal lists (see FIG. 4B) or stored in the

(C) of FIG. 4 illustrates that a plurality of client group terminals G1, G2, ..., Gn are listed and stored in the terminal
In FIG. 4 (c), the first client group terminal G1 grouped from the client terminal 1-1 to the client terminal 1-5 is selected by the specific client terminal. As a result, the client terminals GD selected as the video conference grouping terminal correspond to the client terminals (client terminal 1-1 to client terminal 1-5) selected by the specific client.
In this case, the
The virtualization-based remote video conferencing system is utilized by a corporation or a public institution. Generally, video conferencing is performed by a department or a team. In view of being able to quickly and easily process the configuration of a remote video conferencing system, c) is most preferred.
Meanwhile, the
If it is determined that there is not the same information as the image camera information in the resource information held by the
Upon receiving the request to share the image camera resource, the client terminal converts (or codes) the resource of the image camera through the resource conversion / transmission module and transmits the resource. Then, the connection control module controls the resource of the image camera to be decoded and executed in the
Meanwhile, the video conferencing information transmitted from the client terminal to the virtualization server may be stored in a local storage of the virtualization server itself or in a cloud storage to which security is applied. Specifically, the image information is stored in a virtual machine of the virtualization server using an encoding / decoding technique, and can be stored in a security-enabled cloud storage or in its local storage. The security-enabled cloud storage can be shared by authenticated users (client terminal users). The shared image information can be continuously utilized and reviewed by the client terminal user as needed.
On the other hand, the image information storage involves a rise in the CPU occupation rate, and a decoding technique with good performance is required when the image information is shared at a time through decoding. To this end, the virtualization server may include a hardware-based encoding or decoding card or device, thereby preventing occupancy of the CPU from rising during the image treatment. Specifically, the virtualization server recognizes the encoding and decoding card (device) so that information optimized for hardware performance can be displayed.
In particular, when image information is required to be displayed through a multi-channel, the virtualization server recognizes the encoding / decoding card so that image information can be smoothly displayed. In displaying multi-channel images, In a maximum of 4 screens (the maximum screen number is automatically determined in consideration of hardware performance), the image information is displayed by decoding with a higher performance so that the image quality is higher than that of HD.
The procedure of providing the remote video conference by the virtualization-based remote video conference providing system described above will be briefly described below.
The
Then, when the plurality of client terminals used by the user who intends to participate in the video conference request the virtual server connection, the CB manager performs authentication and allocates the virtual server. In this state, the plurality of client terminals may be connected to the virtualization server, and the image camera may or may not be connected.
Specifically, when the user requests access to the virtualization service through the login procedure through the client terminal, the authentication module of the CB manager compares the login information with the login information of the user information stored in the database, An allocation module allocates a virtualization server optimal for the client terminal, and allocates a virtual machine of the virtualization server.
As soon as the virtual machine is allocated as described above, when the image camera connection is detected or detected by the connection detection /
The image camera
One of the protocol type and the socket type is alternatively selected as the connection mode, and the selection can be continuously changed according to the network status and the transmission rate. A driver that enables transmission by the protocol type and socket type connection is installed in the virtual machine.
Accordingly, the connection control module selectively operates the protocol connection driver or the socket connection driver installed in the virtual machine, so that the resources of the image camera are transmitted in an appropriate communication method appropriate for the communication environment so that the image camera can be executed in the virtual machine .
The connection control module of the server agent accesses the client terminal by a protocol or a socket method to bring the image camera resource through the network and controls the image camera to be executed in the allocated virtual machine.
Here, when the first image camera is connected, the connection control module connects to the client terminal through the protocol method to share the image camera resources. When the communication speed is low or the communication is not smooth, the connection control module switches to the socket method It is preferable to control the connection.
Further, when the version of the device information is high based only on the image camera information, it is possible to connect the device with the web socket method from the beginning without connection in the protocol mode, thereby preventing the speed reduction of the device.
While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
