The accompanying drawings indicate that they are exemplified as a reference to enhance the understanding of the technical idea of the present invention, it is added that the scope of the present invention is not limited thereby.

The present invention relates to a school teaching method and system using the Internet. In particular, the school education method and system for improving the learning effect of students, the desire for excellent lecturers' lectures, and the efficiency of the operation of local school.

Education is a very important means and process for one's social growth. Educated students compete fiercely to get a better college, better job or better opportunities. In addition, schools that educate students strive to be evaluated as better institutions, and private schools compete for better teaching services to gain accreditation, reputation, and profit.

However, these needs and competitive environments have resulted in differences in the level of education or inequalities between the central metropolitan and the provincial cities (or rural). In the case of private schools or academies with better instructors, better facilities, and better curriculum, more students will want to enter. In addition, private schools and academies invest in recruitment, facilities, and curriculum to attract more students or build a reputation. The result was a concentration of high-quality instructors in a central metropolis that was competitive, in demand, and more financially sufficient, and a good school. In addition, high-level schools such as college entrance examinations, certifications, and study abroad were concentrated in central metropolitan cities, and small schools for elementary and middle school students were scattered in local cities. And this educational disparity between the center and the region is recognized as a social problem.

On the other hand, under the influence of the wide spread of the Internet and the development of broadcasting technology, a wide variety of educational methods are proposed and implemented. 1 shows an example of a conventional education system using the Internet, and FIG. 2 shows a schematic configuration of an education broadcasting system through a television receiver.

As shown in FIG. 1, an operator of a web server that provides an education service first captures a lecture with a video camera 1 or the like, encodes it using a video generator 2, and stores the lecture in the media server 3. Put it. The member who accesses the web server through the Internet 4 receives or downloads the training video from the media server 3 through his computer terminal 5. Members can stream or download pre-produced and saved video files. However, such a system was useful for the profit generation of the web server operator who provided the service, but there was a problem that it was not very helpful for the learning effect of the members (students). In other words, a member who is a client can receive content from the server for free or on request at any time, and the client in the server-client relationship is attending training in front of the PC as an individual, not a member of a class. As a result, the concentration on the video lecture is reduced, there was a problem. In addition, since the education is not performed in real time, that is, the time I producing the educational content, the time II encoding and storing the content, and the time III using the content of the client terminal are significantly different from each other. -The response was impossible.

The same problem applies to the system of FIG. The lecture program captured by the video camera 10 in the airwave broadcasting station 20 is transmitted to the television receiver of the indoor 40 via the relay station 30 through the broadcasting system of the broadcasting station. This educational broadcast is not made in the classroom of the school or academy, because there is a problem that the concentration is reduced because it relies on watching TV. In addition, educational broadcasting has a disadvantage of one-way service, and since there is a cost and equipment limitation in producing and broadcasting a program, general private academy or school could not be the subject of broadcasting production.

The present inventors have come up with an opportunity to complete the present invention by rearranging the problems to the following items in order to overcome the problems of the conventional educational environment as described above and to restore the publicity of education.

① Students who live far away from a famous academy want to take lectures from the academy, but are too far away to realistically listen to the lecture.

(2) Streaming and downloading the lectures recorded on the storage media later (streaming and downloading) is not possible in real time because of lack of realism, concentration and unidirectionality.

③ Schools in the provinces are hard to get famous glaciers in big cities because of financial and distance problems.

④ As a result, institutes in the provinces mainly target elementary and junior high school students instead of lectures such as university entrance examinations where the invitation of famous lecturers is important, and the problem of inequality in education opportunities deepens. In Korea, lectures such as college entrance examinations are needed.

In order to overcome the problems of the prior art as described above, an object of the present invention is to provide a live internet lecture method made between the central academy and the local academy.

Another object of the present invention is that the school in the province conducts its own education program, for the lectures (actual lectures-real-time playback through the monitor) at the same time in the center and the local school, the central school This curriculum is shared by local schools, freeing local schools from the cost of research and production of the curriculum and securing of instructors.

Still another object of the present invention is to provide a real-time question-answer between the lecturers currently teaching in the center and the students taking classes in the local academy.

Another object of the present invention is to provide students in the province with the opportunity to practically participate in the high-level education of famous instructors in big cities, and to participate in the lectures in a realistic classroom, to enhance concentration and learning effects. To improve.

Of course, the present invention is to contribute to securing the publicity of education by reducing the burden of private education costs caused by moving to a famous institute in a large city far away to obtain better educational opportunities and by reducing the variation of the central and local educational environments.

On the other hand, other unspecified objects of the present invention will be further considered within the range that can be easily inferred from the following detailed description and effects.

In order to achieve the above object, the live internet lecture method between the central academy and the local academy of the present invention is:

Networking central academies and local academies operating independently of each other and establishing an educational environment;

Generating a media source by capturing in real time a first lecture initiated by a center member within a central academy;

An encoder encodes the media source in real time; And

The media server streaming a video file encoded on a large monitor of a receiving terminal in N local academies networked over the Internet (N is an integer greater than 1) to perform a second lecture in real time for a local academy member It characterized by including.

The present invention may further include posting a curriculum of a central academy to a local academy member.

Also, the present invention inputs a query of a local academy member through a reception terminal of a local academy during a live lecture, and transmits the input query to an instructor terminal of a central academy, and the first lecture and the second lecture about the query. Answering at the same time through the; may further include.

In addition, the first lecture and the second lecture of the present invention is preferably made in the central academy classroom and the local academy lecture room, respectively.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, when it is determined that the subject matter of the present invention may be unnecessarily obscured as matters obvious to those skilled in the art, such as related well-known functions, the detailed description thereof will be omitted.

3 schematically shows a configuration example of a system according to the present invention. Area 1 is the area where real-time lectures are taken in the building of the central academy to create and encode video files in real time. Area 2 is the area where the media server transmits them in real time. Area 3 is the classroom of many local academies. It is an area that is streamed in real time through my monitor. The division of Area 1 and Area 2 is merely an arbitrary division, and is responsible for the production and transmission of content. Area 3 refers to the client terminal area that is connected to the server through the Internet. Importantly, despite the differences in the actual distances between Area 1, Area 2 and Area 3, the lectures take place in all areas in real time.

A media source is generated by capturing a lecture in a lecture room of a central academy using a digital video camera 100 or the like. The encoding system 200 including a PC set and an encoding tool generates a media source from the camera 100. Create a file format that can be streamed. That is, the encoding system 200 encodes the media signal digitized by the capture device into data in a streaming media format in real time. The media server 300 receiving the encoded live broadcast signal transmits the encoded video content in real time through the Internet. The web server 400 may be used together with the media server 300, or may be separately operated to provide a faster and more stable service in consideration of traffic or the number of concurrent users. The digital video camera 100 is Sony FX1 2 set, the encoding system 200 selects DRC 1500 or Osprey, but can use a third-party equipment of the same function, the media server 300 is configured as Window Media Server . Configurations related to other VOD services, subtitles for producing real-time subtitles, microphones, audio equipment, other editing equipment and the like are not shown because they are not directly related to the gist of the present invention. This is the central academy side system configuration.

Next, the institutes located in the provinces, that is, the client side terminals located in the buildings of the plurality of local academies 600 are connected to the central academy side system through the Internet. In the local academy 600, a projector (not shown) and a screen 610 may be installed to monitor equipment, and video lectures currently being shot in the central academy are streamed in real time through a screen serving as a large monitor. . The receiving terminal may be selected as a large monitor such as an LCD or a PDP rather than a beam projector and a screen. A PC set is added within the local academy 600 for interactive query response.

That is, when the operator of the local academy 600 visits the web server 400 and clicks the location information of the live internet lecture content, the web server transmits the location information of the live internet lecture content to the web browser of the operator of the local academy. The web browser executes the streaming player and requests the real-time transmission of the data, and the streaming server transmits the video data of the required live lecture content to the streaming player in real time.

Through the system configuration as described above is to group the Internet education broadcasts, that is, individualized classes that were made at home 40 alone into the classroom of the local academy 600 in the province, which is shown in FIG.

The advantages of the present invention will be revealed through more practical embodiments. As described above, many schools located in the provinces are easy to teach, and thus provide educational services for elementary and middle school students. For example, let's take an example of a school that operates for middle school students. The manager of the middle school is unable to find a good lecturer even if he / she wants to take a high school entrance exam, and gives up a lecture for a high school student because it is difficult to pay the instructor's salary because there are not many students. On the other hand, junior high school students do not usually hold school lectures on holidays, but high school students often hold lectures on holidays. In particular, famous instructors of the Central Academy offer lectures on holidays. As a result, for holidays such as Saturdays and Sundays, the local academy is empty while the central academy is full of students.

However, in the local academy as described above, it is very useful to provide real-time lectures for high school students in the central academy through the system as shown in FIG. First, high school students in rural areas can save time and money by going to a local academy and attending classes at the central academy. Second, the local academy can help improve the profit structure because it can receive facility fees for real-time Internet broadcasting from high school students who have given up. At this time, the weekly weekday week for the Saturday and Sunday or re-entry students will use the empty classroom of the local academy. In addition, because the local academy can use the curriculum for the Saturday and Sunday courses of the central academy, the local academy's administrators are not burdened with the burden of opening a course, developing a curriculum, and selecting textbooks. In other words, the operator of the local academy may provide a lecture schedule as shown in FIG. 5 to a member of the local academy. You will be able to post your middle school education timetable (marked blank) from Monday to Friday, and you will be able to post it on the Saturday and Sunday lecture timetables as you would with the Central Academy. Of course, the local academy can distribute the central academy's educational materials to its members.

6 shows a schematic process of a business model related to the internet live broadcast teaching method according to the present invention. Through the system of FIG. 3, the central academy 150 provides real-time lectures to the local academy 600 and both unify the curriculum into the curriculum of the central academy 150. The local academy 600 provides a classroom to a large number of students 650, provides lectures that are streamed in real time through the reception equipment of the classroom, and also provides a training curriculum or information of the central academy. As a student of the local academy 600, students attend the corresponding classrooms in the local academy 600 where the real-time internet broadcasting education environment is established, and pay a predetermined tuition fee. Although there is no direct face-to-face meeting between the central academy 150 and the students 650, an environment in which questions and answers can be answered in real time using the facilities and equipment of the local academy 600 is established.

Figure 7 shows the overall configuration of the Internet live broadcast lecture method between the central academy and the local academy according to the present invention. First, the central academy and the local academies operating independently of each other to build a network (S100). This is to build the system of FIG.

Next, actual lectures (first lectures) are conducted for the center members within the central academy (S200), and a media source is generated by taking a lecture using one or more digital video cameras installed in the classroom (S300). The encoder then encodes the media source in real time (S400) and encodes to a large monitor (screen) of the receiving terminal in N local academies (N is defined as an integer greater than 1) networked through the media server. The streamed video file in real time (second lecture) (S500).

As described above, two types of lectures exist in the present invention, and at least “N + 1” classrooms and lectures exist. In other words, lectures are given in the classrooms of the Central Academy and in the classrooms of N local academies, and the lectures in the classrooms of the Central Academy are actual training for the instructors and members of the Central Academy (lecturers), and in the classrooms of the local academies. Lectures are lectures streamed in real time from the Central Academy. In the end, only the students and the location of the two lectures differ, and the lecturer, the textbook, and the contents of the lecture are the same.

On the other hand, during the live broadcast lecture, students at the local academy can inquire the lecturer in lecture in the lecture hall of the central academy, and it is possible to raise the sense of reality as this query is broadcast live all over the country in real time. That is, the student of the local academy enters a query through the terminal in the local academy and transmits it to the instructor terminal of the central academy through the internet, and the instructor receives the answer and responds to it. In the past, it was not possible for students of a local academy far away from the classroom to make a query in real time, or to disclose the contents of the query to students of the central academy and students of other local academies.

In the above, the first lecture is given to the members of the central academy in the central academy building, and at the same time, the second lecture is conducted to the local academy members in the local academy building, that is, there is only one first lecture. Explanation was made on the premise. However, in a practical embodiment, two or more different lectures may be held at the same time in the central academy. In general, the central academy has many classrooms, with excellent instructors and a large number of students (students), which allows comprehensive curricula and courses for all subjects. Since each class (class) of the Central Academy is broadcast in real time nationwide, the local academy can open the same comprehensive curriculum and courses as the Central Academy simply by having a terminal and screen that can be connected to the Internet.

In addition, in the case of local academy, there is no need for direct lecturers, and this feature solves the management difficulties of securing excellent instructors of local academies. The lecturer also solves the problem of the classroom given to each instructor because the lecturer is unnecessary. For example, if there are many students and need to create another class, the media server sends the video file of the corresponding class of the central academy through the terminal of the other classroom. Just access it. Therefore, building a live broadcast system that connects to the central academy course in real time within the local academy building can generate more profits by not only solving the instructor problem but also easily accommodating the increase of students.

In another embodiment, in order to increase the efficiency of the real-time lessons of the local academy, through the instructor belonging to the local academy, confirmation learning, supplementary instruction or correction instruction, etc. are combined. This is not an actual course, so you can use a local academy instructor.

On the other hand, the scope of protection of the present invention is not limited by the embodiments explicitly described above. In addition, it should be noted that the protection scope of the present invention may not be limited due to obvious changes or substitutions in the technical field to which the present invention belongs.

Through the configuration of the present invention described above, the institute proceeds to its own education program, but the same content and the same instructor to be taught at the same time in the central and local schools, but the central institute By sharing the curriculum with local institutes, local institutes have the advantage of being free to bear the cost of research and production of the curriculum, and securing of instructors.

In addition, the present invention has the advantage that the real-time Q-response between the current lecturers and students taking the lecture room of the local academy.

In addition, students living in rural areas can listen to the high-quality lectures of famous instructors of the central academy.

In addition, the present invention can reinforce the revenue structure of the institute in the province, and the central institute can create a different structure of revenue through the network with the institute in the province, the present invention is a new chapter of the institute franchise It is based on the real-time broadcasting of the National University's excellent lectures nationwide.

Although effects not specifically mentioned in the specification of the present invention, it is added that the potential effects expected by the technical features of the present invention are treated as described in the specification of the present invention.
