The question of the first user may be displayed on the second screen. The question of the first user is a question input from the first user through the first screen. When the second user manipulates the second user input unit 310 to input a response to the question of the first user, the second controller 390 transmits the input second user's response to the server 100. The communication unit 330 may be controlled. The server 100 transmits the input question to the first terminal 120.

On the other hand, when the second user applies for the right to speak through the voice right application menu displayed on the second screen, the second controller 390 may control the second communication unit 330 to notify the server 100 that the right to speak has been applied. . The server 100 prepares a list of the second users who applied for the right to speak and the second users who are currently granted the right to speak and transmits the list to the first terminal 120 and the

second terminals

130, 140, and 150.

The server 100 instructs the second user terminal entitled to speak to drive the coding unit of the second user terminal granted the right to speak among the second user terminals applying for the right to speak. For example, the server 100 may instruct the second terminal to drive the coding unit 360, and the second control unit 390 of the second terminal may encode the coding unit 360 according to the command of the server 100. Drive the coding program. As a result, the coding unit 360 codes the input voice of the second user. The second control unit 390 may control the second communication unit 330 to directly transmit the coded voice of the second user to the first terminal 120.

Hereinafter, various screens displayed through the first viewer 121 or the second viewer 131 will be described with reference to FIGS. 2 to 6. For convenience of description, the first viewer 121 will be described as an example. The second screen displayed on the second viewer 131 is the same or similar.
