First, as the configuration of the present invention, as shown in FIG. 1, the main controller 10 and the teacher computer 40 are configured on the teacher side, and the student VGA (Video Graphic Array) type color display monitor 30-1 to 30-28 on the student side. ) And auxiliary controllers (20-1 to 20-56) that control textbook selection and dialogue function with the teacher. The main controller has six video channels (50-1 to 50-6) and two audio channels for teaching materials. (50-7 to 50-8) can be connected, and the teacher computer is connected to the teacher computer via RS-232C type serial communication to receive various switching controls. Moreover, this computer controls the teacher-only multimedia data as channel 4.

In addition, a large color television 60 and a speaker 70 can be attached, and there are 28 VGA terminals (1023-1 to 1023-28 in FIG. 3) for the student display monitor. It is connected via serial communication and controls the 56-seat coordinator function.

Here, in detail, the main controller will be described in detail with reference to FIG. 2. As a configuration thereof, one-chip type microcomputer 101 which controls the whole video and audio channel switching and serial communication devices and their switching data are accepted. There is a digital switching device 102 which distributes the signal channel to the students and plays a role of switching, and RS-232C and RS-485 serial communication device 107 for receiving control data of the teacher computer and the coordinator. Methods There are three video signal converters (110-1 to 110-3) (110-1 to 110-3) for converting various video signals (VTR, satellite broadcasting receiver, camcorder, etc.) into student-side VGA display monitor signals. There is a channel 4 video controller 108 and a voice controller 109 that control the video and audio of channel 4, which are dedicated channels. A conversational teacher headset (80) is used for talking with students, which enables the teacher to explain the text to the student. The dialog switching function enables the conversation with not only the whole student but also a certain group of students or a specific student. I can do it.

In addition, there is a large color TV, an external video device, and an external video / audio signal controller that transmits text and video signals to the teacher computer. In particular, the text signal transmitted to the teacher computer can be linked to channel 4, which is a teacher text channel. This associated signal can be used as a teaching aid. Then, the digital switching configuration 102, which is the most essential part, will be described in more detail with reference to FIG. 3. First, as the switching unit configuration, the first switching unit configuration 1022-1 to the 28th switching unit configuration 1022-28 is described. In addition, these switching unit components are internally composed of four digital switching core logic elements. Each switching logic element has two sets of receiving input data four line signals, and each of four sets of four line signals Two lines of data selection control signal are input to allow only one signal to be selected, and this signal is also input to other pairs at the same time so that one selected signal of each pair can be output at the same time. It is formed in the form of a table of truth.

Therefore, referring to the actual switching unit configuration with reference to the function of the above switching element, first, as an input data signal to the first switching element 1022-11, the NTSC-VGA signal converter converts the NTSC signal into a VGA signal. One set accepts the 'R signal' (red signal) four lines (R-OUT1 to R-OUT4) of the VGA video signal, and the other pair receives the 'G signal' (green signal) four lines (G-OUT1 to G-OUT4). And two selection control signals (A1 and B1 signals) are received from the microcomputer (101 in FIG. 2) to simultaneously select one of these four-line signals. G-OUT-1) are output respectively. Similarly, the second switching element 1022-12 has four 'B signal' (blue signals) lines (B-OUT1 to B-OUT4) and four horizontal synchronous signal lines (H-SYNC1 to ...) from the NTSC to VGA signal converter. H-SYNC4) is output and outputs the output signals B-OUT-1 and H-SYNC-1 signals according to the selection control signals A1 and B1 signals commonly connected, and similarly to the third switching element 1022-13. Receives four vertical synchronization signals (V-SYNC1 to V-SYNC4) from the NTSC-VGA signal converter, and outputs the output signal V-SYNC-1 according to the selection control signals A1 and B1.

The fourth switching element 1022-14 has a switching characteristic different from that of the first, second and third switching elements. The fourth switching element 1022-14 is one of the eight input line signals as the three selection control signal (A1, B1, C1 signal) signal. Table 3 shows the truth table of the device for selecting and outputting a signal of?. Therefore, this means that one of the six audio signal lines (AUDIO1 to AUDIO4 and CAS1 and CAS2 signals) must be selected according to the selection control signals A1, B1 and C1. Due to the lack of numbers, an additional fourth switching element 1022-14 having eight input data lines is adopted. Thus, R-OUT-1, G-OUT-1, B-OUT-1, and H- are simultaneously outputted according to the control signals A1 and B1 signals, which are common signals, from the first, second, and third switching elements on a switching unit configuration. SYNC-1 and V-SYNC-1 are joined to one VGA video signal terminal 1023-1 and connected to a predetermined student VGA video display monitor to perform selective switching operation of textbook video from the student side and simultaneously switch to fourth Textbooks relating to the textbook selected from the elements 1022-14 are also selected. In addition, textbook sound is secured by adding two additional audio cassette textbooks to the video textbook. In addition, the channel number of the channel selector button of the student's auxiliary controller is loaded into the RS-485 serial communication data connected to the main controller and input to the main controller.The microcomputer of the main controller receives the data and processes it. After that, it is transmitted to the switching unit configuration of FIG. 3 to be used as a common selection control signal (A1 and B1 signals), which are teaching channel selection signals of the first, second, third and fourth switching elements.

As a whole, as shown in FIG. 3, the total number of switching units is 28 trillion, and each of them is connected one to one to 28 student monitors, considering the total number of 56 students.

Two students are assigned to each monitor, which means that two sets of learning forms are basically formed, and two people per monitor follow the above form because there is no group watching. On the other hand, listening to textbook sounds, conversations between teachers and students, and textbook channel selection functions must be made in one-to-one correspondence with students, so the auxiliary controller that controls this function is assigned to 56 students.

In addition, the role of the student side adjuster (20-1 to 20-56 in FIG. 2) in the present invention is also important, so it looks in detail based on FIG. 4. As shown in FIG. 4, the auxiliary controller 1 (20-1) must first transmit / receive command data from the main controller, and in order to implement the command data, the auxiliary controller 1 (20-1) is connected to the main controller using an RS-485 serial communication method. Command data is received from the main controller via the -485 communication control element 20-12.

These received data are internally introduced into the coordinator control element 20-11 through the 'Com-B0' and 'Com-B4' signal lines, and the coordinator control element 20-11 is directly connected to these serial data. After assembling and processing, perform a predetermined command function. Here, the remaining signals 'Com-B1' and 'Com-B5' signals of the RS-485 communication control device 20-12 are the coordinator 2 (20-2), 'Com-B2' and 'Com-B6' Signal is connected to co-regulator 3 (20-3) and 'Com-B3' and 'Com-B7' signals are connected to co-regulator control elements 20-21 to 20-41 of co-regulator 4 (20-4), respectively. The sub-controllers 2, 3 and 4 (20-2 to 20-4) communicate only in series with the sub-controller 1 (20-1) and only the sub-controller 1 (20-1) communicates with the main controller. I am in charge.

As shown above, the auxiliary controllers 2, 3, and 4 (20-2 to 20-4) are connected and operated by serial communication to the auxiliary controller 1 (20-1). The 4-pole On-Off Dip Switch 20-17, which is set and connected to the RS-485 communication control element 20-12 of the auxiliary regulator, is used to set the identification number of one set of these auxiliary regulators. In FIG. 4, the auxiliary regulator control elements 20-11 to 20-41 are in charge of core functions. First, data is received from the RS-485 communication control element through serial communication, and then assembled and processed. Function to execute command data to listen to the sound or to select whether to talk or not, and to read the key value of the connected keypad (Keypad, 20-16 to 20-46), and call the teacher (Can button) and headset volume control (Volume). Button) and textbook channel selection (Channel button), etc. are also performed, and it is in charge of notifying the student's situation by sending various status changes or commands to the main controller.

It accepts the volume control key values, generates volume control data according to the values, and injects them into the volume control element to enable electronic volume control of the headset. A 7-segment display element is activated to operate the current teaching channel. Numbers can be checked, and when a conversation line selection or textbook selection instruction is input from the teacher side, they are assembled and processed, and then control data are generated and flown into each selection element to control them directly. Then, some embodiments will be described based on the above functions and the like.
