Description

System for English education on the internet}

The present invention relates to an English education system using the Internet, and more particularly, a client for receiving English education accesses a web server through the Internet, applies for a course according to a predetermined form through a user authentication process, and meets the course request. When an optimal group consisting of a small number of clients and instructors is established, the client and the instructor who register for the class can access the service provider's web server via the Internet at a fixed time and use interactive, real-time English via video, voice and other media. It's about a system that allows education to take place.

Recently, as the number of Internet users is increasing rapidly, various kinds of education through the Internet are progressing in various forms, and it is already developed. For example, a remote lecture system that is lectured by lecturers in other regions.

The lectures of the text accumulation transmission method do not break from the existing lecture methods and lecturers and students are gathered in one place, but if anyone wants to lecture, they can open a lecture and learners can take the lecture they want at any time. The most basic step is to have a teacher upload a digital document, download the material, learn it, and send the student results to the teacher on the Internet.

However, since the lecture method through the character accumulation transmission method as described above simply proceeds with the lecture by expressing only the characters, the conversation format cannot be conducted, and thus, the efficiency of the remote lecture and the practical effect of education cannot be provided. Participants who did not understand the meaning of the lecture contents could not understand the contents of the lecture, and there was a problem that the effectiveness of education was deteriorated due to distrust and loss of motivation for the remote video lecture.

Also, if you have any doubt about the contents of the lecture, or if you do not understand it, you should ask questions through the mail or a separate phone call or e-mail. After a long time, you can get the answers to the questions. There was a problem that could not proceed.

Particularly, in the case of English learning, as well as document-oriented learning and conversation and pronunciation learning are very important factors, the lectures through documents alone cannot provide sufficient data suitable for the learners, so they cannot satisfy the needs of the students. Is being raised.

In addition, the expensive remote lecture system has a problem of being used as a system for the convenience of the lecturer rather than the convenience of the lecturer because the burden of the expense occurs to purchase the individual personally because the system itself is expensive.

Accordingly, the present invention has been made to solve the above-mentioned disadvantages and problems, and is provided by a client through a computer terminal connected to a service provider's web server by an image camera and a predetermined internet connection. If you register with the client database by entering the desired course, instructor, and class registration conditions according to the application form, the service provider selects a suitable instructor for each client based on each database information classified and combined by the web server. In addition, by setting an optimal group consisting of the client and the instructor who applied for the course, the client and the instructor who are connected at a fixed time can be trained in real time by the video transmission and reception technology provided by the service provider.The aims of the present invention to provide an English education system is interactive lectures to occur using the Internet so that more effective English language instruction made a face and voice of teachers and students between being displayed on a computer terminal that is bi-directional transmission in real time.

It is suitable when real-time performance is required because there is no need to set up a connection.When sending data to multiple partners at the same time, it can be sent at one time, and data is sent in user datagram unit. Datagrams of any size can be sent as UDP packets.

The video information and the audio information transmitted from the RTP / RTCP engine 107 to the UDP 110 and the TCP 109 respectively pass through a winsock 108, which is called Winsock 108. It is a kind of environment implementation software that acts as an intermediary to allow a PC to make a TCP / IP connection. It supports not only TCP / IP but also various types of connection protocols, and can exchange information between processes connected remotely through a communication network.

In this case, the Transmission Control Protocol / Internet Protocol (TCP / IP) is one of network protocols that are frequently used in LANs. Generally, data is transmitted when data is transmitted through a network. In this case, IP is used to move data packets from one place to another, and TCP is used to manage the flow of data and to verify that the data is accurate.

In addition, the RTP / RTCP engine 107 is a real-time control protocol, the RTP to synchronize the audio and video data to the screen output, each media with its own RTCP packets to report the reception status for each section in the multimedia section That is, video information and audio information are transmitted through the RTP section.

Image information including video and audio information of the client 30 and 40 having the video and audio data flow structure as described above is transmitted to the UDP 110 through the process of the client package 100 of the above process. The computer terminal 51 of the lecturer 50 is directly output to the monitor, and the audio information is output through the sound card of the lecturer 50 via the web server 21 of the service provider 20.

In addition, as shown in FIG. 4, when a lecture is conducted in a unit group consisting of a single client or a few clients and a lecturer, the lecturer and the student are interactively taught in both directions.

As described above, in the English-language education system using the Internet of the present invention, a plurality of clients desiring English education are connected to a service provider's web server via the Internet and register for a course according to a predetermined form. Combining the client database and the instructor database where information is registered to form an optimal group consisting of a predetermined number of clients and instructors, and the instructors and clients that make up a group connect to a web server through the Internet at a fixed time and then use a video camera Is a system that allows real-time English education by image information displayed on a computer terminal and voice information through a speaker, and lectures are performed while watching the image information of the other party displayed on the computer terminal in real time. And not only does the space constraints, not the dialogue between students and between teachers and students can be usefully utilized in the By so done, especially English training, and has the advantage that you can get more than just taking in the actual classroom effectiveness.
