TECHNICAL FIELD The present invention relates to a method and apparatus for sharing a writer among terminals connected to a network,

The present invention relates to a method and apparatus for sharing a deskwriter among terminals connected to a network, and more particularly, it is easy to share information written among a plurality of terminals connected through a network, and an arbitrary terminal can be designated as a server The present invention relates to a method and apparatus for sharing a form between a terminal connected to a network and capable of changing a configuration of a server-client in real time.

In general, when a conference is conducted using a plurality of information terminals such as a video conference, a screen of a user's own screen is transmitted to a large-sized display by using a mobile device equipped with a touch screen or a pen. In this case, a plurality of information terminals are divided into a server and a client. In this case, since only one server can be used, a plurality of information terminals can be used in a conference where interactive sessions are conducted or mutual exchange between a lecturer and a trainee is required. There was difficulty.

For example, when a company conducts a meeting, it typically displays the screen of a specific PC on a large display and shares the screen and conducts the meeting. This is effective for unilaterally conveying the information of the speaker to a large number of users, but there is a problem that when a question or specific supplementary explanation is needed, the screen must be referred to or the presenter's device must be operated directly. Likewise, if someone in the meeting asked a question or needed a specific supplementary explanation, they had to use the PC's input device connected to the large display. Therefore, there was inconvenience that the user must move to the PC or move the wireless mouse to the questioner during the meeting.

Also, in the case of the institute, a class is performed so that a large number of students can view the screen of the terminal by connecting the screen of the information terminal of the instructor such as the tablet to the TV. However, only the contents written by the instructor's information terminal This is because students can not interact with each other.

As a result, multilateral meetings are held, enabling efficient and interactive progression, facilitating meetings, educational programs and other events.

Hereinafter, a method and apparatus for sharing a participant among terminals connected to a network according to an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a flowchart illustrating a method for sharing a participant between terminals connected to a network according to an embodiment of the present invention. FIG. 2 illustrates a method for sharing a participant between terminals connected to a network according to an embodiment of the present invention. FIG.

Referring to FIG. 1, a method 100 for sharing a participant between terminals connected to a network according to an embodiment of the present invention includes a step of forming a network and designating a server (S101), transmitting a server screen to a client (Step S102), combining the screen information transmitted from the client with the screen of the server, and transmitting the screen information to the client again (steps S103 and S104), and designating the new server as a new server in response to the change request to the server .

More specifically, first, a plurality of terminals form one network, and one of a plurality of terminals can be designated as a server (step S101). At this time, any one of a plurality of terminals forming a network can be designated as a server according to a request of any terminal desiring to be designated as a server or a setting of an operator, and terminals other than terminals designated as servers are designated as client terminals.

Here, the network formed by a plurality of terminals may use an internal intranet network using wired and wireless, Internet mobile data, and an Internet router, or may connect using a fixed IP when connecting from the outside, . In addition, since all the terminals must be able to change to the server at any time according to the request of the terminal or the setting of the operator, mutual communication can be connected to all the terminals constituting the network including the server. That is, all the terminals connected to the network maintain mutual virtual communication, and as soon as any one of the plurality of terminals is designated as a server, only the communication connection for server-client configuration is activated centering on the server, Can wait in a deactivated state.

Alternatively, each terminal may store information on all terminals connected to the network, that is, transmission destination and destination information for each terminal. If the terminal is designated as a server, all the remaining terminals are referred to as transmission destinations of screen information and input information And if the terminal is designated as a client, the terminal designated as the current server can be designated as the transmission destination of the input information and the destination of the sharing plan.

Next, the screen information of the server and the screen form information of the server can be transmitted to the plurality of clients (step S102). Here, the display device can access the server as a client and receive screen information. 2 (a), when the terminal A 210 is designated as a server and a plurality of terminals 220 to 240 are designated as clients to constitute a network, the screen of the server 210 is displayed on a network All the clients 220 to 240 can transmit the screen provided by the server 210 in real time in the same manner. At this time, when the user writes on the screen in the server 210, the screen information of the server 210 is changed and the screen information of the changed server 210 is transmitted to the other clients 220 to 240 in real time via the network It is preferable that the screen information transmitted between the server 210 and the clients 220 to 240 is compressed and transmitted and received.

Next, it is determined whether at least one of the plurality of clients receives the writer information on the screen of the client (step S103). That is, if at least one of the clients has a written form, and the information of the written form is transmitted to the server, it can be determined whether or not the written form information is received based on the written form. Here, the formatter formed on the server or the client can be inputted through at least one of a touch screen, a digitizer pen, a mouse, a keyboard, a gyro sensor, an acceleration sensor, a microphone and a camera, for example.

On the other hand, as described above, since all the terminals can write, it is necessary to set the authority so that the written contents can not be edited or deleted. At this time, each user may set his / her own authority on the contents written by him / her, or may set the highest authority so as to give the highest authority authority to edit and delete and to block the communication network of the specific client.

As a result of the determination in step S103, if it is determined that data is received from the client, that is, if a form is input from an arbitrary client and transmitted to the server, the server combines the form information received from the client with the screen of the server, (Step S104). At this time, the server can simultaneously process the screen information transmitted from each of the plurality of clients in a multithread manner.

As shown in FIG. 2B, the information written by the client # 1 220 is transmitted to the server and composited with the screen of the server, and the synthesized screen is transmitted to other clients 220-240 through the network again So that the information written by the client # 1 220 can be shared by all the terminals connected to the network.

As a result of the determination in step S103, if it is determined that data is not received from the client, that is, if no client is input from any client, the screen information of the server and the information written by any client can be continuously transmitted to all clients .

Next, it is determined whether there is a change request from any one of the clients to the server (step S105). If there is a request such that any one client becomes a server, the previous server is designated as a client, (Step S106). At this time, the switching to the client of the server and the switching to the server of the client can be performed by exchanging the information of the terminal designated by the server and the terminal designated by the client, and designating the role of the terminal.

If the server is changed in response to a request from an arbitrary client, the process returns to step S102. In step S102 through step S104, Can be continuously transmitted to each client and shared.

As a result of the determination in step S105, if there is no request to change to the server, the process returns to step S102. In step S102 to step S104, the screen of the server, on which the screen of the server and the written information of the server and the written information transmitted from the client are combined Can be continuously transmitted to each client and shared.

As an application example of the above method, when a company conducts a group conference using one mobile terminal or tablet of each of a large display and five people, the conference organizer outputs a screen of its mobile terminal to a large- The contents of the written form can be output to the large display. At this time, if another participant intends to present other information for raising the objection, the mobile terminal of the respondent is immediately set as a server, and the existing server of the conference organizer is converted to the client again, Display, so that the respondent can use the mobile terminal of his / her own to describe the content of the argument in detail.

In this way, the participants of the conference can view the mobile screen of the respondent in the large display, and the participant of the entire conference can perform the further question or explanation through the remote board by using the mobile terminal or the tablet with the large display at any time.

As another example, in order to conduct a meeting with a company A in the event of an on-site problem, if a total of six people, including on-site field managers, field managers, and department heads of management departments and three related technical staff, The mobile terminal of the department head of the management department which is the manager of the management department can be designated as the server and output to the large display and the remaining five persons can be connected to the mobile terminal of the department head as a client. In such a situation, the head of the department can explain the present state by executing the document or the moving picture, writing it on the touch screen of the mobile terminal or drawing a picture. The rest of the conference members proceed to the conference while watching the same screen as the screen of the mobile terminal of the department head through their own mobile terminal or the large display. In the conference, the field manager pointed out a wrong point, While viewing the screen of the mobile terminal, you can ask questions while writing or painting. At this time, the data input by the field manager is transmitted to the mobile terminal of the department head, which is a server, as a client, and the contents written by the field manager can be displayed on the screen of the department head. The changed screen of the department head mobile terminal can easily understand the contents because all the members are watching.

On the other hand, if it is necessary to call a field worker who is in the field directly and conduct a meeting while watching the actual scene, a mobile terminal of the field worker is set as a server, and all six participants in the company are connected to the mobile terminal You can connect to the client. Accordingly, the screen of the mobile terminal of the field worker is displayed on the large display within the conference hall, and the members of the entire conference can grasp the problem through the actual image. At this time, when any one of the meeting attendees asks a field agent, he can write a specific part of his / her mobile terminal and inquire in detail and detail.

According to the method, the method for sharing the participant between the terminals connected to the network according to the embodiment of the present invention can facilitate the mutual communication of the persons participating in the conference or lecture, thereby improving the efficiency of progress, We can share much information and provide more smooth communication.

The above methods may be implemented by each terminal 210-240 of the participant sharing system 100 as shown in FIG. 3 or the terminal 300 of FIG. 4, and in particular, a software program In which case these programs may be stored on a computer readable recording medium or transmitted by a computer data signal coupled with a carrier wave in a transmission medium or a communication network.

At this time, the computer-readable recording medium includes all kinds of recording apparatuses in which data that can be read by a computer system is stored. For example, ROM, RAM, CD-ROM, DVD-ROM, DVD- , A floppy disk, a hard disk, an optical data storage device, or the like.

Hereinafter, a pantograph sharing system between terminals connected to a network according to an embodiment of the present invention will be described with reference to FIG. 3 to FIG.

FIG. 4 is a block diagram illustrating a detailed configuration of the terminal of FIG. Fig. 7 is a block diagram showing a detailed configuration of a processing unit. Fig.

3, the signboard sharing system 200 between terminals connected to a network according to the embodiment of the present invention includes a plurality of terminals 210 to 240 connected to one network, and a display device 260 ). Here, one of the plurality of terminals 210 to 240 may be designated as the server 210, and the remainder may be designated as the clients 220 to 240. At this time, the display device 260 can always be designated as a client.

The server 210 can transmit screen information of the server 210 and screen information on the screen of the server 210 to the plurality of clients 220 to 240. [ In addition, the server 210 may receive the form information on the screen of the client 220-240 from at least one of the plurality of clients 220-240 and combine it with the screen of the server 210. [

The client 220-240 may receive the screen transmitted from the server 210 and share the same screen as the server 210. [ Here, the screen information output to the clients 220 to 240 may be information obtained by synthesizing information written by any of the clients 220 to 240. The client 220-240 can transmit the entered form information to the server 210 when the form information of the user is input in the same manner as the server 210. [

The display device 260 can receive and output screen information from the server 210 in the same manner as the clients 220 to 240. Here, the screen information output to the display device 260 may be information obtained by synthesizing information written by the clients 220 to 240.

In this configuration, the server 210 and the clients 220 to 240 may be configured identically as the terminal 300 shown in FIG. That is, the server 210 and the clients 220 to 240 can perform a corresponding function depending on whether the terminal 300 connected to the network is designated as a server or a client.

4, the terminal 300 includes an input unit 310, a shared processing unit 320, a communication unit 330, and an output unit 340.

The input unit 310 can input information written by the user. The input unit 310 may include at least one of a touch screen, a digitizer pen, a mouse, a keyboard, a gyro sensor, an acceleration sensor, a microphone, and a camera.

The sharing processing unit 320 performs a corresponding function when the terminal 300 is designated as a server or a client and includes a network management unit 322, a server processing unit 324, and a client processing unit 326.

The network management unit 322 forms a network with other terminals, and can designate either a server or a client in the network. The network management unit 322 can perform switching of the server. That is, when the network management unit 322 receives a change request from the other terminal 300 designated as a client to the server, the network management unit 322 designates the terminal designated as the current server as a client, designates the client that requested the change as a server, Can be performed.

The server processing unit 324 may be operated when the network management unit 322 designates the terminal as a server. The operated server processing unit 324 can transmit the terminal designated by the server, i.e., its own screen information, to another client. At this time, the screen information transmitted to the other client may include the desker information received from an arbitrary client. The server processing unit 324 includes a data converting unit 351 and a data combining unit 353. [

The data conversion unit 351 can receive the writer information on the screen of the client and convert it into data for compositing. The data conversion unit 351 can simultaneously process screen information transmitted from a plurality of terminals designated as clients in a multithread manner.

The data composer 353 can synthesize the writer information received from any client, that is, the data converted by the data converter 351, on the current screen.

The client processing unit 326 may be operated when the network management unit 322 designates the terminal as a client. The operated client processing unit 326 can transmit the terminal designated by the client, i.e., its own screen information, to the server. At this time, the information transmitted to the server may be the information written by the user.

As described above, the server processing unit 334 and the client processing unit 336 can selectively operate according to the designation of the network management unit 332.
