On the other hand, Figure 4 is a block diagram of the EDUCE platform required to receive a two-way real-time remote visit and additive learning guide service of each client (10,11) according to the present invention.

The client (10, 11) has an EDUCE platform 20 for performing the control necessary for the distance learning map as shown in Figure 4, the EDUCE platform 20 using the CD (10, 11) It can be installed and used on a hard disk or a system server 16 can be downloaded and configured.

The EDUCE platform 20 includes an EDUCE controller 21, a streaming media controller 22, a learning lecture viewer 23, a video conferencing viewer 24, and a video on demand viewer 25. ), A white board module 26, a recording module 27, a learning controller 28 and a communication controller 29.

First, the EDUCE controller 21 serves as an interface between the learning controller 28, the communication controller 29, and the media controller 22 as a controller of the entire system, and various data coming from each user through communication. (Control data used in the explanatory tool 35 to be described later, multimedia data required for VOD, video and audio data used in video conferencing, real-time multimedia data used in internet broadcasting lectures, etc.) are analyzed.

After interpreting the data, the control data used in the explanation tool 35 is directly sent to the learning controller 28 and processed by the learning controller 28 to be output to the electronic blackboard module 26. If all the multimedia data other than the control data is downloaded and reproduced, it is difficult to process in real time. Therefore, the multimedia data is sent to the streaming media controller 22 for processing according to the reception, and the data is processed and reproduced through the corresponding application.

In the case of the data necessary for the progress of the education, the operation of granting the speaking right, releasing the speaking right, participating, inviting, leaving, etc. is performed through the learning controller 28. First, in the case of granting the right to speak to the copyboard and video conferencing, it creates an environment that can be input to the copyboard, and in the case of video conferencing, the capturing and encoding of video and audio data through the streaming media controller 22 is possible. do. In the case of release of voice, the electronic board makes an environment that cannot be input, and in the case of video conferencing, encoding cannot be performed. In the case of participation and invitation, it is possible to connect the communication session to use the current video conference and the electronic blackboard, and send the current situation in progress to maintain the same screen. In case of leaving, all currently active applications are terminated and the network environment is initialized.

The streaming media controller 22 edits / authors a capture module 22a for capturing or recording video and audio data in accordance with media generation, and for synchronizing video, audio and text data on a time axis. It consists of the (Editor / Auther) module 22b.

In addition, the streaming media controller 22 compresses the synchronization data and media data generated for synchronization according to the transmission protocol to reduce the amount of data, and on the contrary, an encoder / decoder for decoding and interpreting the transmitted multimedia data for playback. / Decoder) 22c, which data format is based on Moving Picture Expert Group (MPEG) 4.

Therefore, the streaming media controller 22 displays the capture of video and audio data and displays the media playback order on the time axis in such a manner that the media data is played in real time as the media data is transmitted instead of the media data downloaded. By performing editing / writing to solve the synchronization problem for each media, and encoder / decoder function to compress and decompress network traffic using bulk data compression.

In the case of internet broadcasting, the learning lecture viewer 23 has a function of showing the actual lecture scene through the camera to all the students in the whole country, and uses the media stream method, which is a unidirectional real-time multimedia processing technology. That is, the learning lecture viewer 23 has a function of receiving and displaying a real-time learning paper education live broadcast, and is used to broadcast a special lecture of the learning paper to the learning paper service providers.

The video conferencing viewer 24 is a capture module 22a for capturing face images and voices of students and teachers, which are received through a web camera and a microphone when the user drives the video conferencing driving button 39g at the time of learning and teaching a work sheet. The captured data is formatted using the encoder 22c and sent to the learning controller 28 to show the learning paper education situation of students and teachers in the distance.

The learning controller 28 controls the functions of starting the learning education required for the education of the workbook and participating in the perceived student's education, requesting questions, and releasing questions for smooth learning of the workbook, and using the information of students participating in the workbook. It serves as a conduit for substantial communication to take place in the communication controller 29.

The VOD viewer 25 is a module for viewing educational materials to be referred to when learning a learning paper, and is shown to a user by downloading and playing supplementary materials for a learning paper education by downloading a multimedia data of a CD-ROM or a prepared form.

In addition, the recording module 27 makes it possible to record scenes and voices for teaching the learning paper in the user PCs 10 and 11, rather than communicating through a communication medium when the lecture recording button 39f is pressed by the user. Under the control of the EDUCE controller 21, it is stored in the hard disk of the HDD and can be played back in the stored hard disk later.

Therefore, using the recording module 27 can record / play back the current workbook education, and also, when the workbook teacher records the contents to be learned in advance at the time of seating, and uploads it to the server, the student can learn as if the teacher does not have a real teacher. The same effect can enhance learning.

The electronic blackboard module 26 provides a blackboard function that can be explained to the students during the teaching of the workbook, and has internet surfing, a function of sharing the workbook writing tool, and a text chat function. Data transfer in the copyboard module 26 uses a TCP / IP (Transmission Control Protocol / Internet Protocol) based communication because a small amount of data is required because the teacher uses the explanation tool 35. Its data is important data on the student's side, so it is necessary to confirm that it was sent and received when sending and receiving.

Since the communication controller 29 is responsible for the actual transmission and reception of the real-time multimedia data, it has a UDP (User Datagram Protocol) and a TCP / IP-based communication program, and maintains independence from the upper application and lower communication due to modification of the upper application. It is a module that can minimize the change of the module and is responsible for the actual communication session, data transmission, etc. of the Internet and local area communication, and a communication protocol for the Internet 13 and local area network (LAN) 12 at the bottom. There are (13a, 12a) layers.

In addition, the lecture process may be recorded by using the recording function using the recording module 27, and then reviewed at any time after the learning is completed.

In this way, the method of teaching correction is expected to have the same effect as the teacher visiting the student's home at a certain time.

Hereinafter, referring to the flowchart of FIG. 10, a bidirectional real-time distance learning map teaching method according to the present invention will be described in detail.

The present invention is a method for supporting an education system for supporting real-time learning and non-real-time learning, which is an education system support method. The teacher first solves the problem of the workbook by html editors 42, Hangul 43, and Excel (MS Excel). 44), such as PowerPoint (MS Power Point) (45), Word (MS Word) 46, etc. by using a web editor or a general word processor to produce a learning paper (41) to be trained (S300), the Internet to students Submitted to the system server 16 through 13 (S301).

Then, in the case of the real-time learning of the learning paper, the student downloads the learning paper 41 (S302), and in the process of solving the learning paper, the teacher and the student solve the problem through the process of questions (S304) and online (S305) (S303). .

That is, the student's question is to apply for a voice by clicking the voice control button (39d) in the student EDUCE screen (30b), and if the teacher accepts the voice, the student uses the description board 35 to have a workspace (electronic board function) 32) Record the questions and questions to be asked using text and various pen attributes.

Accordingly, student EDUCE 20b captures the event of the student's question, objectizes the event (e.g., if the student wrote "?" In the freehand curve, student EDUCE 20b moves to freedraw 35a). It captures in the form of the starting point, the end point, the color, and the thickness of the displayed line.) The data is transmitted to the teacher EDUCE 20a through the Internet 13 and the system server 16. The received teacher EDUCE 20a interprets the event and performs it on his electronic blackboard. In this form, when the student's question and the teacher's response are made, the screen consistency can be guaranteed. This is called an event sharing method.

Conversely, if the teacher wants to respond to the student's question, the teacher's EDUCE 20a captures the problem by determining the property of the pen. For example, if the captured event is "A", the event is sent to the student EDUCE 20b in the form of a free throw (point, end, color, thickness). When the student EDUCE 20b interprets and executes it, a free curve written by the teacher "ga" appears on the student's electronic blackboard 32. Therefore, the student can receive the instruction of the study sheet as if the teacher visited and face-to-face.

On the other hand, in the case of additive education, the student downloads the workbook (S306), solves the workbook (S307), uploads it to the web server 160 through the Internet 13, and stores it in the DB according to the student ID and the workbook subject. If (S308), the teacher downloads the workbook that the student has solved (S309), scores (S319), and if the answer is incorrect, upload the correct answer and solving process to the web server 160 to deliver to the student (S310) ). The student downloads and reports the teacher's correction instruction (S311).

The videoconferencing driving button 39g and the recording button 39f are used in the above-mentioned visiting and correcting guidance process. When the video conference driving button (39g) is operated, the teacher's lecture learning paper training course is captured through the camera and the voice received through the microphone is recorded (encoded) (S312, S318), and all the learning papers except the self through the transceiver are provided. It is delivered to the participants (S313). The transferred video and audio data are classified into whether the video data received through the video and audio playback (decoding) module is a student or a teacher, and the teacher screen 33 and the student screen of the video conferencing system of the EDUCE 20a, 20b. (34) Output to each part.

Due to the processing performance of the system, the video conferencing system was designed to output only the teacher's video and the student's voice, and the rest of the students watched and listened to the teacher's and the student's voice.

In the current study, 1: 1 voice means no voice, so both voice and video of students and study educators are printed. In the case of 1: N workbook training, it is intended to operate under the constraints of these systems. When a student asks a question during learning, the student requests a voice by clicking the control button 39d. When the student approves it, the student captures the voice and face of the student and delivers it to both the teacher and the learner's PC. (S314).

Repeat this process until the end of the lesson. And if necessary, the student or teacher will record the current learning process, and after the end of the learning to play at the desired time to review (S316).

Therefore, the present invention enables the learner learner to study the study paper regardless of the place and time through the local area network or the Internet without a separate learning device, it is possible to maximize the learning effect through the interactive learning process.

That is, the present invention provides an economical and efficient educational environment through education services with creative thinking, diversification of educational information delivery, and virtual education services.
