Referring to FIG. 2, the user accesses the authentication system 130 of the video education site through the first terminal 210-1 and registers as a member (S101). When registering as a member, at least one personal terminal storing a unique identifier such as a mobile phone and the like is set as well as a user ID and password for logging in. The authentication system 130 stores the information registered by the user in the user database 132 (S102).

After that, when the user accesses the video training site 100 through the first terminal 210-1 through the HTTP protocol and logs in, the authentication system 130 performs the first login authentication with the registered ID and password and successfully logs in. When the message chat operating system 140 requests the user to create a message chat space (S103 ~ S105).

Accordingly, the message chat operating system 140 examines the socket pool 112 and allocates a web socket to the first terminal, generates a message chat space, and responds to completion (S106 to S109). The authentication system 130 transmits the PIN number to the first terminal 210 and guides the access to the PIN number through the second terminal (S110).

Accordingly, the user accesses the video education site 100 through the second terminal 210-2 storing a unique identifier such as a phone number or biometric information and then inputs a PIN number (S111). The second terminal 210-2 transmits the unique identifier information stored in the second terminal 210-2 together with the input PIN to the video training site 100, and the authentication system 130 of the video training site is a PIN. If the second authentication is successful by performing the second authentication using the number and the unique identifier information of the second terminal, the message chat operating system 140 requests the message chat registration of the second terminal 210-2 (S112 and S113). .

Accordingly, the video lecture system 120 provides a video lecture to the user's first terminal 210-1, and the user watches the video lecture of the first terminal 210-1 (S118 and S119).

When it is time to submit the assignment to check whether the lecture contents are understood while watching the video lecture, the video terminal of the first terminal 210-1 is paused and the guide information such as the task information is provided and the second terminal 210-2 is provided. Display the task for confirming the degree of understanding of the content through the (S120 ~ S121). Assignment can be done in a variety of ways, including four-choice, short-answer, narrative, audio input, and document submission.

When the user inputs an answer to the task through the second terminal 210-2, the video training site 100 evaluates the inputted answer and passes the next video lecture through the first terminal 210-1 when the answer is passed. And, if it does not pass, re-taking or other video lectures of a lower level are provided according to a predetermined rule (S122 to S128).

As described above, according to one embodiment of the present invention, the second terminal is authenticated through a second personal terminal different from the first terminal for viewing the lecture, and thus, abnormal attendance is prevented and the second terminal is different from the lecture viewing terminal. By submitting assignments and evaluating them in real time, learning efficiency can be improved through interactive learning.

In addition, according to an embodiment of the present invention, according to the result of the performance evaluation, the first terminal (210-1) can be arbitrarily changed the playback section of the video being reproduced to have a variety of services with one lecture video, According to the performance evaluation result, the player of the first terminal may continuously play the video other than the current playback video to evaluate the learning and achievement. Here, the second terminal 210-2 may be implemented as another program of the first terminal 210-1.

On the other hand, in the case of a real-time two-way online lecture, the lecturer configures one message chat space through one web socket, and the trainee who wants to take the lecture is a web socket. Through the authentication number to participate in the message chat space (message chat) through a message chat (message chat) space can be accessed.

Through this, the lecturer can directly confirm the attendee who is currently connected to watch his lecture, and can authenticate attendance. In this case, the lecturer plays the lecture playback player through authentication at the first terminal 210-1 which is connected for the first time. A player may be configured, and personal authentication may be performed using a PIN number and personal authentication information through the second terminal 210-2. Here, the personal authentication information may be a registered user number or telephone number or biometric information recorded in the terminal.

In the case of an online real-time lecture by the instructor, the necessary query during the lecture can be directly transmitted to the lecturer through the second terminal 210-2, and the lecturer commands a message to the individual trainee who made the query or to the entire trainee. You can also send the message, and the electronic document such as Word or Excel related to the answer to the query can be delivered through the Web RTC.

The lecturer can inquire the instructor directly to submit the assignment before completing the lecture, and the inquired learner can send the assignment directly to the instructor in the name of each individual instructor through the Web RTC. In this way, in the embodiment of the present invention, the lecturer can collect the results of the task to verify the certification of each individual to all trainees or individuals, and can immediately react.

In addition, Web RTC, which can submit assignments and share video, can secure stability by distributing network traffic required from the service provider side that provides one real-time live video. The same effect can be achieved without installing (Grid) software.

In addition, in the service of the present invention, if authentication for a user accessing a web RTC is added separately, a reward for the traffic burden as much as the user contributes may be provided to each individual user.
