Description

{SYSTEM AND METHOD FOR MANAGING LECTURE CONTENTS}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lecture content management system and method, and more particularly, to a lecture content management system and method for efficiently managing lecture contents in real time on site.

The lectures to be taken according to the individual various purposes (for example, learning) are largely conducted on-line or off-line.

In order to teach on-line, the contents of video lecture should be preceded. The contents of the video lecture will be produced in a studio equipped with broadcasting equipment.

On-line lectures are advantageous in that students do not need to go directly to a specific place, so there is no space limitation. However, video lecture contents produced in studios are limited in the variety of lectures. That is, since only the content of the lecturer's lecture invited to the studio is produced as the content, the diversity of contents of the lecture can not be limited.

While offline lessons are limited by space, questions and answers can be made in real time, and presence and participation can be improved. In addition, in recent offline lectures, various electronic equipments are provided for each lecture room, and lecture and learning efficiency are improved. However, since the off-line method is one-time, there is a disadvantage in that it can not be repeatedly taken. Therefore, although the lecture is recorded or recorded personally, the lecture is repeated, but the recording and recording are not smoothly performed due to the surrounding environment. In addition, copyright issues may arise if the content of recorded and recorded lectures deviate from the intended use.

On the other hand, when online and offline lectures are combined, there is a problem that the learning effect is decreased because the online lecture and the offline lecture do not coincide with each other. Also, since each cost is separately required to take the lecture, There is a problem in that a burden is generated.

In this paper, we propose a lecture method in which inquiry and response are performed through two - way communication based on online method. However, the number of students is limited.

In this manner, the management operating unit 96 performs a function of applying the tuition fee differently in correspondence with the off-line lecture attendance or combining the illegal copying technique related to the copyright with the video lecture contents.

Hereinafter, a method of operating a content of a lecture of the present invention using the system configured as described above will be described.

17 is a flowchart of a content operation method of a lecture according to an embodiment of the present invention.

Referring to FIG. 17, a membership subscription process is performed between a learner terminal and an integration server (S1). That is, a process of joining a student who takes a course in a school offline or offline is performed (S2). In the present embodiment, the case where the membership is made by the connection between the student terminal and the integration server is described, but the integration server can perform the membership addition by itself in the integration server using the student information provided by the institute. The integration server performs member registration.

On the other hand, in the local server, the content of the video lecture produced by the video lecture contents production equipment is stored in the local database (S3). The production of video lecture contents will be described in detail with reference to FIG.

Subsequently, the local server transmits the content of the video lecture to the integrated server (S4).

The integrated server stores the content of the video lecture (S5).

Thereafter, if there is a request for a specific content in the student terminal (S6), the integration server checks whether the user who requested the specific content is a member, whether to take an offline lecture, etc. (S7) (S8).

When the search for the specific content is completed, the integration server transmits the specific content to the student terminal (S9).

The specific content is output to the student terminal (S10).

Meanwhile, the integration server counts the number of downloads for the specific content (S11) and distributes the revenue (S12).

Then, the integration server delivers the revenue distribution information to the local server (S13).

The local server stores the revenue distribution information (S14).

On the other hand, the profit distribution of the administrator operating the integrated server and the school operating the regional server can change the distribution ratio based on the time when the installation and management costs of the video lecture contents production equipment are all compensated.

On the other hand, when the specific contents are transmitted to the student terminal, it is preferable that the integration server transmits the copyright information together so that illegal copying and use can not be performed.

18 is a flowchart of a method of producing a moving picture lecture content according to the present invention.

Referring to FIG. 18, in response to the sound propagated from the sound source position (lecture position), each sound collector generates a sound signal and transmits it to the sound controller (S31).

The voice controller measures the time difference of each transmitted voice signal (S32).

The voice controller generates position data from the time difference of the voice signal and outputs it (S33).

Then, the position data is transmitted to the mobile camera, and the mobile camera moves the mobile camera corresponding to the position data (S34). Thereafter, it is preferable that the lecturer can be photographed more accurately through a video tracking technique or the like. On the other hand, the fixed camera captures, for example, a part or all of the blackboard in a fixed manner.

On the other hand, the time difference is corrected corresponding to the time difference of the audio signal (S35). At this time, it is preferable to correct the reference of correction based on the strongest speech signal. Of course, it can be corrected on the basis of the speech signal which is inputted first among the speech signals. Subsequently, the voice controller outputs the voice data obtained by synthesizing the time-difference-corrected voice (S36).

Then, the video data photographed from the mobile camera and the fixed camera are mixed with the audio data transmitted from the audio controller (S37), and the mixed video lecture contents are stored in the local database (S38).

On the other hand, when a speaker is connected to the voice controller, the lecture voice can be output in real time through a speaker as a field sound.

When a wired / wireless communication device for transmitting a moving picture to the mixer is connected, the moving picture can be delivered to a field student in real time.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
