The control unit 203 may include a lecture content conversion module 215 for converting the lecture contents stored in the lecture content storage module 214 into the data format of the associated broadcasting equipment; And a lecture contents transmission module 216 for transmitting the lecture contents converted by the lecture contents conversion module 215 to the associated broadcasting equipment.

The communication means 204 may transmit the contents of the lecture stored in the storage means 180 to the broadcast server in cooperation with the control means 203 to implement external broadcasting.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described in detail with reference to FIGS. 1 to 4. FIG.

First, a lecture content creator places a portable steel storage device 200 at a desired position in a lecture room or a classroom, and uses a storage mode changing means 170 such as a remote controller in a state where power is supplied through a power supply portion 205 Enter the recording start control command.

When the recording start control command is transmitted, it is received by the signal input unit 202 in the portable steel storage device 200 and is transmitted to the control means 203. Here, the signal input unit 202 receives the infrared signal transmitted from the storage mode changing unit 170, and transmits the command information of the lecture contents producer to the control unit 203.

When the recording start control command is inputted, the control means 203 controls the entire operation of the portable steel storage device 200 to produce the lecture contents.

At this time, when the lecture data input unit 201 starts lecturing while displaying contents to be lectured by the lecturer (educator) in the lecture room or the classroom on the display device 110, the lecture data input unit 201 transmits the lecture data input from the strong personal computer 120 to the display device 110 And receives the audio / video data to be transmitted through the first HDMI input terminal. And receives the instructor image acquired through the camera 130 via the second HDMI input terminal. Here, the camera 130 uses the automatic lecturer position tracking function to smoothly track the position of the lecturer and acquire the lecturer image even if the lecturer does not stay in one place but moves during the lecture. If necessary, the camera 120 can use the HD webcam. Also, the student image data photographed by the student camera 140 is input via the CVBS input terminal. These student image data provide the ability to objectively observe student responses during class. In addition, the video data reproduced by the actual presenter 150 such as a video player is inputted through a USB input terminal. Although it is not shown in the drawing, it is preferable to receive the voice of the instructor through the speaker.

Each piece of steel information input through the steel material input unit 201 is transmitted to the control unit 203 and the steel content creation module 213 in the control unit 203 is set by the storage mode changing unit 170 The lecture information acquired through the lecture data input unit 201 according to the storage mode is combined on the basis of Android to generate lecture contents. Here, the storage mode is either a PIP (Picture in Picture) storage mode or a PAP (Picture Add Picture) storage mode. The lecture content creator can change the storage mode at any time by using the storage mode changing means 170. [ For example, if the PAP storage mode is selected in the state of generating the lecture contents in the PIP storage mode, the lecture contents are generated in the PAP storage mode. The generated content of the lecture is displayed on the screen through the display device 160 in real time. The lecture contents creator can check the contents of the lecture produced through the display device 160 in real time. It is also possible to freely change the size and configuration of the screen by using the storage mode changing means 170.

In the PAP storage mode, a lecture content screen is generated by displaying a lecture data image on a main screen and a lecture moving image background image is displayed on a screen outside the screen, and the lecture contents screen is stored. Here, the lecture video background image information may use at least one of the lecturer introduction information, the lecture title, and the sequence as the background image information.

FIG. 4 is an example of a screen when creating and storing lecture contents in the PAP format. Here, (1) is a lecture screen on which moving image background image information of a lecture is displayed, and (2) is an area for displaying participant (e.g., student) list information. When displaying the participant list, you can select and display the questioner. (3) is a region for displaying a questioner image (photographed by a student camera), (4) represents a chat window (character chat, on / off is possible), and (5) represents a content sharing transmission window. Here, on the lecture screen, information such as lecturer introduction information, lecture title, order, and the like can be displayed.

The content of the lecture generated in this way is temporarily stored in the lecture content storage module 214 and stored in the associated storage unit 180. [ The storage means 180 may be implemented as a storage device such as a micro SD card or a network device.

When the instructor lectures through this process, the contents of the lecture can be conveniently and inexpensively produced on the basis of the Android using the storage device 200 of the portable steel. Particularly, by using the portable steel storage device 200 and producing lecture contents based on Android, lectures can be conveniently stored and broadcasted in various places without restriction of time and space.

Meanwhile, as another feature of the present invention, the contents of the lecture can be transmitted to a remote broadcasting system through a classroom or a communication network, and learning can be performed using lecture contents at another place almost simultaneously with lecture contents production.

For example, the lecture contents conversion module 215 converts the lecture contents stored in the lecture contents storage module 214 into lecture contents in the data format of the associated broadcasting equipment. That is, the lecture contents are converted into an appropriate data format for intranet broadcasting. This is to allow the screen to be viewed by another personal computer, a secondary monitor, or a smart device when the resolution of the electronic board of the room is high or the beam projector screen is dark. The lecture contents transmission module 216 transmits the lecture contents converted by the lecture contents conversion module 215 to the communication means 204 for intranet broadcasting or Internet broadcasting.

When the communication means 204 is intranet broadcasting, the communication means 204 transmits the content of the lecture to the electronic blackboard, the auxiliary monitor, the smart device, or the like. This makes it possible to broadcast the lecture content, which is a recorded video of the lecture, to the classroom in real time.

Also, in the case of Internet broadcasting, the communication means 204 transmits contents of the produced lectures to a mobile phone, a PC / TV, a tablet, etc., in connection with a streaming server which is a broadcasting server. Here, it is preferable that the communication unit 204 converts the contents of the lecture into MPEG2-TS / HTTP, Ethernet, Wi-Fi, and 3G / 4G formats for Internet broadcasting and transmits the contents to the streaming server 300 as a broadcasting server . Thus, the contents of the lecture can be confirmed in near real time in a lecture room, a conference room, or a classroom located at a remote place.

Although the present invention has been described in detail with reference to the above embodiments, it is needless to say that the present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the spirit of the present invention.

The present invention is applied to a technology for producing and delivering lecture contents on an Android basis inexpensively and conveniently.
