In particular, the demand for video contents for recording lecture contents of lecturers is on a continuously increasing trend. Such video content has an advantage that the user can utilize the video content without being limited by place or time through the online education service and can repeatedly view and listen as needed.
In order to create video contents in real time, a camera is installed in a classroom in which a lecturer performs a lecture, and a photographer takes an image of the lecturer by changing the position of the camera according to the movement of the lecturer and records the image of the lecture contents. The photographed image is stored in the memory device, and after the lecture is finished, the lecturer or the manager directly monitors and edits the recorded content, and registers the edited lecture image in the server.
However, such a conventional video content recording method has a disadvantage that additional time and labor cost are required for image editing work after the off-line lecture is taken. That is, the inefficacy of the video editing time exceeding the video capturing time frequently occurs. In addition, in the case of a service provider who provides both collection lectures and on-line lectures, there is a problem that the service of collection lectures and on-line lectures is almost impossible at the same time, and the service time of on-line lectures can only be delayed.
In addition, the conventional video content recording method has a problem that a long editing time and a high editing technique are required when supplementary learning materials for improving the learning effect of lectures, such as internet information, multimedia materials such as photos and videos, and presentation materials, are added to the lecture content.

Such a real-time video content creation system 100 can create video content in real time without requiring additional complicated editing work during image capturing, and can be conveniently used for creating various video contents such as video lectures, conference images, and personal presentation images.
The image capturing unit 110 captures an image of the outside to generate image data, and transmits the image data to the image capturing content generating unit 120 that generates the image data. As the image capturing unit 110, various image capturing units capable of capturing images, such as a video camera, a network camera, a digital camera, and a camera built in a mobile terminal, can be used.
The image capturing unit 110 may have an auto-tracking function. That is, the image capturing unit 110 can automatically perform the zoom-in or zoom-out operation according to the position of the instructor, thereby capturing the appearance of the instructor. Such an automatic tracking function may be implemented using markers or sensors, or using only photographic images. By using the automatic tracking function of the image capturing unit 110, the screen displayed on the display unit 130 can be automatically switched by recognizing the movement or gesture of the instructor. A specific method for such automatic screen transition will be described later.
The audio input unit 115 receives external sound to generate audio data, and transmits the audio data to the content generation unit 120. The audio input unit 115 may be a variety of audio input units that can convert external sound such as a lecturer's voice into an electric signal using a microphone or another microphone provided integrally with the image capturing unit 110. The audio input section 115 may include a microphone, a level amplification section, an audio mixer, and the like.
The imaging content generation unit 120 receives the video data and the audio data from the video imaging unit 110 and the audio input unit 115, and generates imaging content. The image data of the image capturing unit 110 may be provided to the capturing content generating unit 120 through an image signal conversion device such as a video card or a video capture board. The audio data of the audio input unit 115 may be transmitted to the photographic content generating unit 120 through an acoustic signal conversion device such as a sound card. The photographed content generating unit 120 can generate documents in various formats from the video data of the video photographing unit 110 and the audio data of the audio input unit 115, which are processed by digital a/V streams, and store the documents in the storage unit 125. The photographic content generated by the photographic content generator 120 can be played back by a video playback program, the video of the photographic content can be displayed on the display 130, and the audio 741 can be output by the audio output unit 135.
The storage unit 125 can store various auxiliary material contents, the photographic contents generated by the photographic content generation unit 120, programs capable of playing the photographic contents and the auxiliary material contents, respectively, and the video contents generated by the control module 155. Here, the auxiliary data content may be various data such as image data, picture data, web page data, electronic document data, and the like.
The display unit 130 selects the shooting content and the auxiliary material content and displays them on the screen. The screen of the display portion 130 may be divided into a main image portion 131 and a sub image portion 132(Picture In Picture) smaller than the main image portion 131, and the photographing contents and the auxiliary material contents may be selectively displayed on the main image portion 131 and the sub image portion 132. That is, when the auxiliary material contents selected from the image data, the picture data, the web page data, and the electronic document data are displayed in the main image portion 131, the photographed contents or other auxiliary material contents can be displayed in the sub image portion 132. In addition, the photographed contents can be displayed in the main image portion 131, and in this case, the subsidiary contents can be displayed in the sub image portion 132.
When video content is created in real time during an on-line lecture or a conference, the video displayed on the display unit 130 may be provided to the listener in real time. By displaying the same image as the image displayed on the display unit 130 on a display device installed in a classroom, a conference room, or the like for the audience, the attention of the audience can be increased, and the content can be more effectively delivered to the audience.
As shown in fig. 4 to 8, the user input module 140 includes an input module body 141 and a plurality of selection parts 142, 143, 144, 145, and 146 which are disposed at intervals on the input module body 141 and generate selection input signals selected by a user. When the user selects one of the plurality of selection parts 142, 143, 144, 145, 146, a selection input signal is generated, and the generated selection input signal is transmitted to the control module 155. The control module 155 can select the photographing contents and the contents of the auxiliary materials according to the selection input signal of the user input module 140 and display the same on the main image portion 131 and the sub image portion 132 of the display portion 130. Accordingly, the user can easily switch the screen displayed on the display unit 130 by using the user input module 140.
The selection units 142, 143, 144, 145, and 146 of the user input module 140 may be set to match the program for playing the photographic content and the program for playing the auxiliary material content one-to-one, respectively, and for example, as shown in fig. 4 to 8, the program played in the main video unit 131 may be converted based on the selection input signals generated in the plurality of selection units 142, 143, 144, 145, and 146, respectively.
That is, among the plurality of selection units 142, 143, 144, 145, 146, one selection unit 142 is set to match a program for playing the video data of the subsidiary data content, another selection unit 143 is set to match a program for playing the picture data of the subsidiary data content, yet another selection unit 144 is set to match a program for playing the web data of the subsidiary data content, yet another selection unit 145 is set to match a program for playing the electronic document data of the subsidiary data content, and yet another selection unit 146 is set to match a program for playing the photographic content.
Specifically, as shown in fig. 4, in the case where one of the selection parts 142 is selected according to a user operation, a selection input signal of the user input module 140 may be transmitted to the control module 155, and the control module 155 may display a program for playing back image data on the main image part 131. At this time, the sub-image portion 132 can display the contents of the shot or other auxiliary materials.
As shown in fig. 5, in case that the other selector 143 is selected according to the user's operation, a selection input signal of the user input module 140 may be transmitted to the control module 155, and the control module 155 may cause a program for playing the picture material to be displayed on the main video portion 131. At this time, the photographed contents or other auxiliary material contents can be displayed on the sub-image portion 132.
As shown in fig. 6, in case that the selection part 144 is further selected according to the user operation, the selection input signal of the user input module 140 may be transmitted to the control module 155, and the control module 155 may display a program for playing the web material on the main image part 131. At this time, the photographed contents or other auxiliary material contents can be displayed on the sub-image portion 132.
As shown in fig. 7, in case that the further selection part 145 is selected according to the user's operation, the selection input signal of the user input module 140 may be transmitted to the control module 155, and the control module 155 may display a program for playing the electronic document material on the image part 131. At this time, the photographed contents or other auxiliary material contents can be displayed on the sub-image portion 132.
As shown in fig. 8, in the case where another selection unit 146 is selected according to the user operation, the selection input signal of the user input module 140 may be transmitted to the control module 155, and the control module 155 may display a program for playing the photographed content on the main video unit 131. At this time, the auxiliary data content can be displayed on the sub-image portion 132.
In this way, if the plurality of selection input signals generated by the plurality of selection units 142, 143, 144, 145, 146 are preset to match the program for playing the photographic content and the program for playing the auxiliary material content in a one-to-one manner, the user can easily switch the screen of the display unit 130 during lecture or presentation. Therefore, the user can create lectures or presentations in real time without having to provide a separate sub-display in addition to the main display, as in the conventional video content creation system, and without having to select a necessary program with a mouse or the like and perform a troublesome operation of displaying the program on the main display. That is, high-quality video content can be easily produced without removing unnecessary video frames due to troublesome operations through an editing process after recording.
The user input module 140 may be changed to various different configurations, in addition to the configuration including the plurality of button type selection parts 142, 143, 144, 145, 146 generating the selection input signal by the pressing operation as illustrated. That is, the user input module may have a different configuration having a variety of different forms or a variety of different selection type selection units, and may be communicatively connected to the control module 155 in a wireless or wired manner. In addition, the number of the selection units provided in the user input module can be variously changed, and the program matching each selection unit can be variously selected by the user.
The electronic blackboard writing section 150 generates a blackboard writing input signal corresponding to a user operation. The electronic blackboard writing unit 150 may be formed in various configurations such as a touch panel that can generate a blackboard writing input signal by recognizing the contents of a blackboard writing such as a picture or characters drawn by a user with a finger or a stylus pen. The blackboard-writing input signal generated in the electronic blackboard-writing part 150 may be transmitted to the control module 155, and the control module 155 may receive the blackboard-writing input signal to display the contents of the blackboard-writing of the user on the screen of the display part 130. The content of the electronic blackboard-writing part 150 may be displayed so as to overlap the content of the auxiliary material displayed on the display part 130, and the user may add necessary pictures or characters to the content of the auxiliary material displayed on the screen of the display part 130.
The control module 155 may run a program for executing the contents of the photographed image and a program for executing the contents of the auxiliary material, and control the display unit 130 to convert the images displayed on the main image unit 131 and the sub image unit 132 of the display unit 130. Further, the control module 155 generates video content from the video displayed on the screen of the display unit 130.
That is, the control module 155 may record the played audio simultaneously with the image displayed on the display unit 130 being captured in real time by using a program capable of recording and recording the image and the audio played on the system. In addition, documents in various formats can be generated by processing the reproduced video and audio with a digital a/V stream and stored in the storage unit 125. Accordingly, video contents including images of the contents of the main image portion 131 and the sub image portion 132 displayed on the display portion 130 and audio contents such as the voice and audio contents of the user played at the same time can be generated in real time without requiring a separate editing operation. A program capable of recording and recording images and audios played on the system in real time may be stored in the storage section 125.
As described above, the control module 155 may convert the contents displayed in the main image portion 131 and the contents displayed in the sub image portion 132 of the display portion 130 among the photographing contents and the contents of the auxiliary material according to the selection input signal of the user input module 140. The control module 155 may automatically switch the screen displayed on the display unit 130 according to the user's motion or gesture by using the auto-tracking function of the image capturing unit 110.
For example, the control module 155 may display different screens on the display unit 130 for a case where the user is located close to the image capturing unit 110 as shown in fig. 2 and for a case where the user is away from the image capturing unit 110 for blackboard writing as shown in fig. 3. That is, when the user moves away to a predetermined range for writing on a blackboard while the main image portion 131 displays the contents of the auxiliary material, the control module 155 may automatically switch the screen of the display portion 130 so that the contents of the shot user are displayed on the main image portion 131. On the other hand, when the user moves to the vicinity of the image capturing unit 110 again, the screen of the display unit 130 can be automatically switched to the original state by the control module 155.
In addition to this, the real-time production system 100 of video content may include a communication section 160 for network communication. The real-time video content creation system 100 can receive web materials through the communication section 160 or transmit the generated video content to the outside.
A method for producing video content in real time using the system 100 for producing video content in real time as described above will be described below.
First, the user determines the contents to be displayed on the display unit 130 before the lecture or presentation is started, and sets the program for playing the photographic contents and the program for playing the auxiliary material contents to be matched with the selection units 142, 143, 144, 145, and 146 of the user input module 140 one-to-one. The program for playing back the content to be displayed on the display unit 130 may be executed before the start of lecture or presentation, and the program not played back on the main video unit 131 or the sub video unit 132 of the display unit 130 may be executed in the background so as not to be visible on the screen.
When a lecture or a presentation is started, the image capturing unit 110 captures an external sound such as a user's appearance and transmits the captured image data to the captured content generating unit 120, and the audio input unit 115 receives an external sound such as a user's voice and transmits the audio data to the captured content generating unit 120. At this time, the photographed-content generating unit 120 may process the video data of the video photographing unit 110 and the audio data of the audio input unit 115 using the digital a/V stream to generate documents in various formats, and store the documents in the storage unit 125. The photographed content generated by the photographed content generating unit 120 can be displayed in real time on the main video unit 131 or the sub-video unit 132 of the display unit 130 by a playback program.
The user can select the contents displayed in the main image portion 131 and the contents displayed in the sub image portion 132 among the photographing contents and the contents of the subsidiary material by viewing the screen displayed in the display portion 130 during the lecture or the presentation and operating the user input module 140 as required. In addition, when the user uses the electronic blackboard writing portion 150, the content of the blackboard writing portion 150 and the content of the auxiliary material displayed on the display portion 130 can be displayed in a superimposed manner.
The screen displayed on the display unit 130 may be automatically switched according to the user's motion or gesture by the auto-tracking function of the image capturing unit 110. Such an automatic screen switching operation may be preset by the user.
In this way, in the process of displaying the photographed contents or the subsidiary material contents on the main image part 131 and the sub image part 132 of the display part 130, the control module 155 can record the played audio while capturing the image displayed on the display part 130 using a program capable of recording and recording the image and the audio played on the system, thereby generating the video contents. The generated video content may be stored in the storage section 125 or transmitted to the outside through the communication section 160.
As described above, the real-time video content creation system 100 according to an embodiment of the present invention can record images in a captured manner while various contents such as a photographic content and an auxiliary material content are displayed on the screen of the display unit 130, and record audio to be played, so that a user can create video content in real time while a lecture or a presentation is being performed.
In addition, the real-time video content creation system 100 according to an embodiment of the present invention can rapidly convert the screens displayed on the main video part 131 and the sub video part 132 of the display part 130 by the user input module 140 generating the selection input signal with a simple operation of the user, and thus can easily create high-quality video content dynamically presenting various contents even by a user who is not skilled in the operation of a mechanical device or an electronic device.
In addition, the real-time video content production system 100 according to an embodiment of the present invention can represent the photographic content and various auxiliary material contents of the user captured during the course or presentation of the user on one screen in real time, thereby greatly reducing the editing time and cost.
While the present invention has been illustrated and described above in connection with the preferred embodiments for the purposes of illustrating the principles of the invention, it is not intended to be limited to the details of construction and operation shown and described. Rather, it will be apparent to those skilled in the art that various changes and modifications may be made to the present invention without departing from the spirit and scope of the appended claims.
