In general, English is not only the language spoken by the people of England, the United States, Canada, Australia, etc., but also the most widely used international language in the global village. Therefore, it is difficult to obtain the information necessary for survival in a rapidly developing globalized society without knowing English. Since English is now a means of survival as a means of survival, the need to learn English has emerged.

Due to the necessity of the above-mentioned necessities, many language schools have been established, and accordingly, more than a certain size of L / L (Language Laboratory) is being operated at each language school or university.

In order to operate the above-described language lab, a communication system for delivering lecturers or learning contents spoken by a school system to each student or user should be configured. The conventional communication system of a typical language lab is for communication between students and teachers. Wired communication method using a cable is commonly used.

On the other hand, referring to the configuration and operation of the user terminal in the transmission mode with reference to FIG. 5, the clipper referred to by reference numeral 410 filters only the synchronization signal carried with the voice signal as in the reception mode. The N-bin counter referred to by reference numeral 420 receives a synchronous signal filtered through the clipper 410 as a clock and counts from 0 to N-1 so as to be unique to the device that each terminal has. If the number matches, the switch (not given a reference number) is turned on.

In addition, the holding adjustment 430 is provided to adjust the holding timing to prevent cross talk with neighboring voice signals when the driving signal between the N-counter counter 420 and the switch is transmitted.

Looking at the method according to the present invention with reference to the accompanying drawings, when the teaching content by any association or training in the teacher-side device to the voice system is transmitted to the main system port 100 to be delivered to a plurality of students Delivered.

The main system port 100 performs a function of branching and outputting to the assigned channel of each student to receive and transfer the learning content spoken by the teacher, and is separated into each channel accordingly.

The voice signal divided into each channel is synthesized into one integrated channel to be carried on one communication cable through the de & multiplexer 200.

In this case, the type of the signal synthesized as the integrated channel is as shown in FIG. 2, except that the same content (or may be different content) is loaded in a region called a reception band.

Then, since the terminal as shown in FIG. 4 is connected in parallel to the transmission cable of the de-multiplexer 200, the clipper 410 receives a voice so that each receiving terminal receives only data transmitted to itself. The synchronous signal loaded with the signal is filtered to pass only the corresponding synchronous signal, and based on this, the N-ary counter 420 receives the synchronous signal filtered through the clipper 410 as a clock and counts each signal from 0 to N-1. If the terminal matches the device's unique number, the switch (no reference number) is turned on.

Therefore, when the N-counter counter 420 turns on the switch, the speaker (including the headset) connected to the switch expresses the voice signal transmitted from the teacher as a sound.

On the other hand, if the student learns or follows the companionship by nurturing it, it is converted into an electric signal through the microphone shown in FIG. 5, and the converted electric signal is transmitted when the switch is on. It is done. At this time, since the transmission time of each transmitting terminal can transmit data only at the time allocated to each transmitting terminal, it is transmitted using the clipper 410 and the N-bin counter 420 shown in FIG. 2 is as shown in FIG. 2 except that data exists in a transmission band.

Therefore, the data individually transmitted from the transmitting terminals connected in parallel are received through a single cable connected to the de & multiplexer 200 shown in FIG.

In this case, the channel discriminator 310 detects and recognizes the synchronization signal shown in FIG. 2 and performs a function of recognizing a channel by a counter, and the address decoder 320 uses the channel discriminator 310. Provides information about the recognized channel to the de-multiplexer 200 to prevent the mixing and transmission error of data when the de-multiplexer 200 divides one channel into a plurality of channels. .
