BACKGROUND OF THE INVENTION Conventionally, in this type of television lecture room, a question processing method has been used in which a speaker makes a statement to the lecturer by pressing a breathtalk switch attached to a microphone, etc., and when the speaker finishes speaking, the breathtalk switch is turned off. It came.

Problems to be Solved by the Invention However, the general public is not familiar with the above-mentioned question processing method using BreathTalk communication, so it is difficult to switch it off.
There was a time when the question time could not be used effectively because the call time continued to be used up by asking questions and then being turned on even after the questions were finished.

The present invention solves these conventional problems, and after requesting a question and being allowed to ask a question, simply speak into the microphone, and the voice of the person asking the question can be heard by the instructor and other classroom students. The purpose of this invention is to provide a method for processing questions in a television lecture in which a speaker is made to amplify the sound through a speaker, and a microphone is released immediately after the question is finished.

Means for Solving the Problems In order to achieve the above-mentioned purpose, the present invention transmits speech request information to a central control device through a communication line when a participant in a TV lecture presses a speech request switch, and then sends speech request information to a central control unit in each classroom. The central control unit selects the speaker according to predetermined logic, displays it on the display of the classroom concerned via the control line, turns on the question microphone, and transmits the content of the statement again via the communication line and the central control unit. The system is configured to amplify the sound into each classroom via the device.

Therefore, according to the present invention, question requests from multiple classrooms separated from each other are automatically processed, and students who have received permission to ask questions can perform complex operations simply by speaking in front of the microphone. Since it is not necessary, it has the effect that even beginners can easily master it.
