Description
[0001] The present invention relates to a storage and broadcasting system for a portable steel, and in particular, a portable storage system based on Android is used to record a lecturer and a training screen in a classroom or a lecture room in real time, And more particularly, to a storage and broadcasting system for a portable steel which maximizes usability.
Recently, there have been many cases of providing various learning services through virtual cyberspace such as internet and communication. One of them is video lecture or video lecture through the Internet.
In order to save the professor's lecture as a video and send video lecture and video lecture to internet broadcasting, space like a separate broadcasting equipment and studio is needed.
In particular, in order to produce image contents, a camera is installed in a lecture room in which a lecturer lectures in order to record an image of lecture contents of a lecturer, and a camera photographer who is skilled in the operation of a camera zooms the lecturer in or zoom out, and photographs the instructor while changing the position of the camera to record the video of the lecture contents. Such lecture contents recording requires a skilled cameraman, and recording equipment uses expensive and complicated equipment.
Therefore, it is required to develop a technique for producing video lectures and video lectures more easily and conveniently, and broadcasting the produced lecture videos.
On the other hand, conventional techniques for producing lecture contents for video lectures and video lectures are disclosed in
The prior art disclosed in
With this configuration, the instructor is automatically tracked with optimized image size while tracing the position of the instructor according to the movement of the instructor.
The prior art disclosed in
Through such a configuration, the lecture of the institute is processed through real time video through the Internet, and video of lecture lecture is transmitted through the Internet, so that the lecture students can be utilized as a review material.
However, the above conventional techniques require a skilled cameraman to take a lecture of a lecturer, a camera for photographing a lecturer, and an expensive complicated separate apparatus for producing lecture contents by synchronizing the photographed image and voice .
In addition, the conventional technique of photographing a learning scene of a lecturer or a class participant using a fixed camera and recording lecture information in synchronization with a voice is inconvenient for a lecturer to lecture at a fixed position.
In particular, the conventional techniques have a disadvantage in that it is impossible to broadcast the recorded steel information in real time in connection with the classroom broadcasting.
SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above problems, and it is an object of the present invention to provide an apparatus and method for real-time recording of a lecturer and a training screen in a classroom or a lecture room using an Android- And to provide a portable lecture storage and broadcasting system which can maximize the usability by enabling real-time broadcasting in the classroom.

Another object of the present invention is to provide a portable lecture storage and broadcasting system capable of providing a competitive solution for a massive open online course (MOOC) and flipped learning, which is a new trend of universities around the world.
According to an aspect of the present invention, there is provided a storage and broadcasting system for portable steel, comprising: a camera for photographing a lecturer to acquire a lecture image; A steel material input unit receiving steel material displayed on the camera and the display device; Storage mode changing means for changing the storage mode during storage of the lecture contents; Control means for controlling the recording of the lecture information acquired through the lecture data input unit according to the storage mode set by the storage mode changing means on the basis of the Android and controlling the broadcast of the recorded lecture contents; Storage means for storing contents of the recorded lectures in cooperation with the control means; And a display device for displaying the contents of the recorded lecture on the screen in cooperation with the control means.
In this case, the camera uses a Full HD camera and automatically traces the instructor through the instructor tracking function.
The display device may be an electronic whiteboard.
Wherein the steel material input unit comprises: a first HDMI input terminal for receiving a photographed image of the camera; A second HDMI input terminal receiving a screen of a lecture transmitted from the display device; A USB input terminal for inputting information of an actual presenter; And a CVBS input terminal for inputting the learner image acquired by the student photographing camera.
The storage mode changing unit may generate a storage mode change signal to change the storage mode to one of a PIP (Picture in Picture) storage mode and a PAP (Picture Add Picture) storage mode.
The storage mode changing means uses a remote controller for generating a ripe recording control and a storage mode changing signal from a remote operation.
In the PAP storage mode, a lecturer and lecture data image is displayed on a main screen, and a lecture moving picture background image information is displayed on a screen outside the screen. The lecture moving picture background image information includes lecturer introduction information, lecture title, , And inserts the information.
The control means may include a recording control module for controlling start and stop of recording; A storage mode determining module for determining a storage mode according to a storage mode selection of the storage mode changing means; A lecture contents generation module for generating lecture contents by combining lecture data respectively transmitted from a lecture camera, a student camera, a strong personal computer, and an external image device according to the storage mode determined by the storage mode determination module; And a lecture content storage module for storing lecture contents generated in the lecture content generation module in a storage means.
In addition, the control means may include a lecture contents conversion module for converting lecture contents stored in the lecture contents storage module into lecture contents in a data format of the associated broadcasting equipment; And a lecture contents transmission module for transmitting the lecture contents converted by the lecture contents conversion module to the associated broadcasting equipment.
The storage means may be a micro SD card or a network device.
In addition, the storage and broadcasting system of portable steel according to the present invention includes communication means for broadcasting in real time the content of a lecture stored in the storage means in cooperation with the control means.
The communication means communicates with the control means and transmits the content of the lecture stored in the storage means to the broadcasting server to implement the external broadcasting.
According to the present invention, it is possible to produce a simple and inexpensive video content for MOOC and Flipped Learning, thereby providing a competitive solution.
In addition, according to the present invention, by recording lecture information on the basis of Android, there is an effect that a user can conveniently make and utilize lecture information.
In addition, according to the present invention, there is also an advantage that the storage mode can be freely changed by controlling the steel storage system by a simple operation of a remote controller or the like.
According to the present invention, there is an advantage that the information of the recorded lectures can be linked with the in-school broadcasting system in real time without time delay, and the class can be taught with the same lecture information in other classrooms.
In addition, the present invention has an advantage in that steel storage information can be linked to an external broadcasting apparatus and remotely broadcasted to the outside.
