Method for Creating Digital Contents with Information on Computer Monitor Screen}

The present invention relates to a method for generating digital content in connection with a computer data screen. In particular, the present invention can generate digital content in a form in which media information such as video or audio input to a computer device is linked with a material screen presented through a computer screen. Make sure

As computer and network technology advances, the importance of digital content that can be processed by computers and distributed through the network is increasing.

Digital content can be produced in various forms, and can be divided into a method of producing a computer using various software and a method of photographing using a photographing means such as a digital video camera.

Each of the two methods has its advantages and disadvantages.

The former method has the advantage of freely processing the contents and composition of digital contents according to the user's ability or the function of software, but it is difficult to reflect the situation occurring in the real world in real time.

On the contrary, it is easy to capture or record the situation in the real world as it is and reflect it in real time, but it is difficult to process the content and composition of digital content freely.

As a specific example, suppose you are creating learning content. In the former case, the instructor can easily handle the materials (images, videos, statistical graphs, etc.) that the teacher wants to present to the students. It's hard to reflect what you're trying to convey.

On the other hand, in the latter case, the lecture process can be photographed as it is, so that the instructor can easily reflect what the instructor wants to convey to the students, but it is not easy to present various reference materials to the students.

In this case, the video image of the lecture and the data processed on the computer may be mixed, or the video image and the computer screen may be combined into one by taking a picture of the lecture at that time while the video is output.

However, mixing video images and data processed on a computer requires specialized skills, which makes it difficult for the general public to handle them, and it is inconvenient and indirect to include a computer screen at an appropriate time in video shooting.

In particular, since video images and computer data screens are combined into a single video image, independence is lost, and parallel information transmission is impossible.

Accordingly, the present invention has been made in order to solve the above problems, a form that can be processed in parallel without losing the independence of the media information input from the digital video camera or microphone and the data screen presented through the computer screen The purpose of the present invention is to provide a method for generating digital content in connection with computer data screens that can be linked to a computer.

In order to achieve the above object, the digital content generating method associated with the computer data screen according to the present invention comprises the steps of outputting a user interface for a digital content generation operation on a monitor screen by a content generation tool installed and executed on a computer device; ; Receiving, by the content generation tool, a content type to be generated in association with a computer data screen from a user through the user interface; When the user instructs the creation of the content, the content generation tool encodes the information input from the corresponding media input device connected to the computer device according to the designated content type and the display information output on the monitor screen of the computer device, respectively. Starting to create a file and a screen file; And terminating generation of the media file and the screen file according to the content generation end instruction of the content generation tool.

In particular, the content generation tool generates a packaging file that can specify the generated screen file and media file.

The content type may include one of a video image input from a digital video camera and audio input through a microphone.

The user interface may be configured to allow a user to specify encoding information along with the content type.

In this case, the content generation tool encodes the information input from the media input device and the display information output on the monitor screen of the computer device according to the encoding information designated by the user.

The generating of the screen file may be configured to access and encode display information in a memory of a video card provided in the computer device and processing information to be output on a monitor screen.

The user interface may be configured to allow a user to designate a project name and a storage path for each project. The content generation tool may generate a folder having a corresponding project name in a storage path designated by a user, and include a packaging file associated with the project, Save media files and screen files.

If one or more of the project name and save path is not specified by the user, it can be treated as the default value.

The user interface may provide a content editing window for editing the contents of media files and screen files belonging to a specific project.

In this case, the content generation tool may re-encode and update the media file and the screen file edited through the content editing window, respectively.

The content generation tool may provide a user interface for upload that allows a user to upload a packaging file, a media file, and a screen file belonging to each project to a specific server.

According to the present invention, the user can produce digital content including both the media information and the computer data screen in a simple process of recording a desired image or recording a voice while outputting necessary data on the monitor screen of the computer.

The media file encoding the media information input from the media input device and the screen file encoding the computer data screen are independently generated. The media file and the screen file belonging to each project are managed through the packaging file. Can be identified during playback.

The computer data screen is encoded in real time at the same time as the video image or audio input from the media input device, and the video data is reproduced.

In particular, when media information such as video or audio is associated with a material screen output on a monitor screen of a computer, the information transfer ability is further improved as compared to digital content having only one form.

Anyone who is not an expert can easily create and distribute high-quality digital contents because the user does not need an inconvenient and difficult process such as including a computer screen in the image being photographed.

As a specific example, the course content consisting of the video of the lecture and the data screen presented through the computer screen is uploaded to a specific server through a communication network and distributed to each student through VOD (Video On Demand) or streaming service. Can be.

The network interface 10-8 allows the computer device 10 to be connected to various communication networks 13 such as a wired internet network or a wireless internet network.

Referring to FIG. 2, an embodiment of a digital content generation method associated with a computer data screen according to the present invention will be described.

When the user executes the content generation tool installed in the computer device 10 (S21), the content generation tool outputs a user interface (UI) on the screen of the monitor 11-6 (S22).

The user interface may be configured in various ways for the convenience of the user, and may be configured in the form of a graphical user interface (GUI) including various menus.

3 illustrates an example of a basic user interface 30, which may indicate a 'file' menu, an 'edit' menu, a project menu 31, a setting menu 32, and a start of content generation having one or more submenus. The start button 33, the end button 34 for instructing the end of content generation, the video image output window 35, etc. are provided, the role of which will be described in the relevant section.

First, the user designates a content type he / she wants to create using the setting button 32 of the user interface 30 (S23).

Designating a content type in step S23 may be understood as a process of determining which of the media input devices connected to the computer device 10 is inputted from the media information to be associated with the computer material screen.

The media input device refers to a device capable of inputting media information, such as a video image or sound, into the computer device 10. For example, a digital video capable of converting photographed image information (A / V) into a digital signal for transmission. The camera 11-5, the web camera 11-4, the microphone 11-3 which can input a voice, etc. are mentioned.

The content type related to the present invention includes a computer data screen in the media content input from the media input device, but also provides a method for generating digital content using only information input through the media input device in order to provide a variety of user convenience and selection. Can support

4 shows an example of a window 40 that allows a user to easily select a desired content type by presenting a content type composed of various combinations. Screen, combination of 'microphone and computer', combination of 'camera and microphone', and 'microphone'.

In this case, the encoding information, for example, the resolution, the number of frames per second, the bit rate, the number of channels, and the like may use a preset default value, or may be processed so that the user directly designates it within a possible range.

In the upper right window 42, the type of camera (digital video camera, web camera, etc.), the type of microphone (audio), and the profile can be set.

The profile represents specific encoding information. For example, in the case of a video image, a profile may be designated with a resolution of 320 * 240 and frames per second of 30fps, and audio may be specified with a bit rate of 1 channel and 16kbps.

In the lower right window 43, the type and profile of the monitor screen can be set. For example, if the profile does not need to maintain a high frame rate, a resolution of 1024 * 768 and about 5fps can be specified.

On the other hand, the video image output window 35 of the user interface 30 outputs a video image input from the media input device. When the user selects a content type including a computer data screen, the user interface 30 is digital. Minimize when the creation of content starts.

When the user clicks the start button 33 provided in the user interface 30, the content generation tool starts to generate the media file and the screen file according to the content type designated by the user in step S23 (S24).

That is, the content generation tool starts to generate the media file by encoding information input from the corresponding media input device connected to the computer device 10, and simultaneously encodes the display information output on the monitor screen of the computer device into a video. To begin creating the screen file.

At this time, the content generation tool encodes using the default value or the value specified by the user depending on whether the user specifies the encoding information.

If in the example shown in Fig. 4 the user has specified a combination of 'camera, microphone' or 'microphone', only the media file will be created in step S24.

Encoding the display information output on the monitor screen of the computer device in step S24 is performed by accessing the corresponding display information from the memory of the video card 10-5 processing the display information to be output through the monitor 11-6. Can be used.

In addition, the information input from the microphone 11-3 may be encoded by mixing with the audio information processed by the sound card 10-6.

If the user clicks the end button 34 provided in the user interface 30 while generating the media file and the screen file in step S24, the content generation tool ends the generation of the media file and the screen file (S25, S26). .

In particular, the content generation tool generates a packaging file for each project that can specify a media file and a screen file.

The packaging file refers to a file that indicates what screen files and media files constitute the digital content.

The packaging file may have various structures and formats as necessary since the content reproduction tool needs to be able to recognize the content when the digital content generated according to the present invention is subsequently played back.

As one example, the packaging file may be generated as a file in XML format.

If the user selects each content type in the example of FIG. 4, the packaging file 51 includes a video file name cam.wmv and a screen file name screen.wmv as shown in FIG. 5A, or shown in FIG. 5B. Audio file name (cam.wav) and screen file name (screen.wmv) as shown, or only video file name (cam.wmv) as shown in FIG. 5C, or audio file name as shown in FIG. 5D. (cam.wav) only.

Where .wmv is the video file format, .wav is the audio file format, and the video and audio files are media files. These video files and audio files may be encoded to have any format related to the video file and the audio file in addition to the .wmv format or the .wav format.

With reference to FIG. 6, the process of generating digital content according to the present invention will be summarized.

Depending on the content type selected by the user, display information output from the monitor screen of the computer device 10, video information captured by the digital video camera 11-5 or the web camera 11-4, and the microphone 11-3. The audio and mixed information input through and processed by the sound card 10-6 are encoded (S61, 62), respectively, and are made of media files (video files or audio files) and screen files.

In addition, a packaging file for indicating which media file and screen file are generated corresponding to the project is generated (S63).

When to create a packaging file can be configured in various ways as needed. When a user creates a project, when the user specifies a content type, when the user instructs to start generating content, encoding of digital content is generated. And when finished.

One digital content is composed of a media file, a screen file, and a packaging file.

Therefore, files constituting each digital content need to be managed separately, and then, even if the digital content is distributed and used by others, each file included in the digital content must be managed collectively.

To this end, the content creation tool allows users to create and manage digital content on a project basis.

7 illustrates an example in which folders for each project are formed in the storage medium 10-4 of the computer device to manage digital content on a project basis.

That is, media files, screen files, and packaging files generated in relation to the project exist in the project # 1 folder or the project #n folder, respectively.

The user interface 30 may include a function for allowing a user to create and manage digital content on a project basis.

As a specific example, the user may select the project menu 31 of the user interface 30 to display the project setting window.

8 shows an example of the project setting window 80, a user inputs a project name in the project name input box 81 and a path for storing files related to the project in the storage path input box 82. Referring to FIG. In this case, when the browse button 83 is clicked, a search box is output and the user may select a storage path by using the search box.

When the user clicks the confirm button 84, the input of the project name and the storage path is completed, and when the cancel button 85 is clicked, the project setting process is canceled.

When the user designates the project name and the storage path, the user interface 30 creates a folder having the specified storage path and the project name and stores files related to the project in the folder.

If one or more of the project name and the storage path are not specified by the user, the user interface 30 may designate a name or a storage path by default, such as a name or a current path consisting of the current date and time.

Meanwhile, the user interface 30 may support a function of providing a content editing window so that a user can edit the contents of media files and screen files belonging to each project.

The content editing window may include various functions, and in particular, may be configured to allow a user to delete a specific section.

Referring to FIG. 9, when the user instructs editing through the edit menu of the user interface 30, the content editing window is output to the monitor screen of the computer device 10 (S91).

The user may designate a specific section to be deleted among the contents of the media file and the screen file through the content editing window (S92).

If the user designates a section to be deleted in step S92 and issues a delete command (S93), the content generation tool updates the media file and the screen file by re-encoding the specified section from the corresponding media file and the screen file in a deleted state (S94). ).

The user can continue editing in the content editing window or finish editing and close the content editing window (S95, S96).

10 illustrates an example of the content editing window 100, in which a user may select an editing target packaging file by using an open item in a file menu.

The content editing window 100 may include a source information window 101 showing bibliographic information of a media file (cam.wmv) and a screen file (screen.wmv) belonging to a package file to be edited, and a media playback window (i.e., a media file being played). 102, a screen playback window 103 for playing and displaying a screen file, and a deletion section designation window 106 for allowing a user to designate a section to be deleted based on playback time information.

The media playback window 102 and the screen playback window 103 output media files and screen files, respectively.

The user can play or pause the media file and the screen file by operating the play button 105-1 of the play tool window 105, and click the end button 105-2 to end the play or the volume. The volume can be adjusted through the adjustment bar 105-3.

Deletion section designation window 106 is provided with a timeline for displaying the playback time in the form of a line so that it can be easily identified, and various tracks informing the playback time of the media file and the screen file. Each track is activated according to the content type, and the user can adjust the playback time by moving the time bar 106-1.

An example of a method of specifying a deletion section by a user will be described.

The user places the time bar 106-1 at any point of the section to be deleted and clicks the 'S' button to display a start time.

As shown in the example of FIG. 11A, the time bar 16-1 is positioned at another point, and then the end point is displayed by clicking the 'E' button.

As such, when the two points are designated, the content editing window 100 confirms that the points between the two viewpoints are designated as deletion targets in the form of an X mark.

In this state, the user may immediately instruct the deletion of the corresponding section.

Alternatively, as shown in FIG. 11B, as shown in FIG. 11B, the user drags the shortening mark 11 to the starting point to give the effect as if the corresponding section was deleted once, and then according to the user's instruction. You can also finally delete the section from the media file and the screen file.

The above example is only for better understanding of the description, and a method of designating a section to be deleted and a time or method of finally giving a delete command to the user may be variously configured as necessary.

According to each embodiment described above, the digital content generated by the user may be distributed to others.

To this end, the content generation tool may provide an uploading user interface for uploading packaging files, media files, and screen files constituting each digital content to a specific server.

12 illustrates an example of an upload user interface 120 in which a user inputs an IP address of a server in a host input box 121, and an ID and password in a user name input box 122 and a password input field 123, respectively. After inputting the button, click the connect button 124, the content generation tool is connected to the server through the communication network.

When connected to the server, the folder structure of the storage accessible to the user is displayed in the server's structure window 128-1, and the detailed structure of each folder and the file list included therein are displayed in the file window 128-2. .

The user searches the folder structure of the local computer in the structure window 127-1 of the local computer and selects a destination to be transmitted in units of files or folders appearing in the file window 127-2. When the user instructs transmission, the uploading user interface 120 transmits the corresponding file or folder to the server.

Figure 13 shows an example of a system for distributing digital content created according to the present invention to general users via a communication network.

Each user 131 who has created digital content using the content creation tool uploads to the content management server 135 via the communication network 13, and each digital content uploaded to the content management server 135 is uploaded to the database 135-. It is stored and managed in 1).

The content management server 135 may provide digital users stored in the database 135-1 to general users who want to use digital content in various ways, such as a video on demand (VOD) or streaming method.

The user terminal of general users using digital content may be various types such as a personal computer (137) or a portable terminal (138), and each user terminal (137, 138) may reproduce digital content generated by a content generation tool. The content reproduction tool 139-1 is installed.

Referring to FIG. 14, a process of executing digital content generated according to the present invention will be described.

The general user (user who wants to use the digital content) executes the packaging file of the specific digital content in the user terminal (S141).

The content reproducing tool 139-1 checks whether the corresponding packaging file is a normal file, and checks which media file and screen file should be played through the information contained in the packaging file.

The content reproduction tool 139-1 displays a content output window for outputting the media file and the screen file on the screen of the user terminal (S142).

The content output window may include a media play window for playing a media file, a screen play window for playing a screen file, and a control box for allowing a user to control playback of content.

The content playback tool 139-1 now decodes the media file and the screen file, respectively, and outputs them to the media playback window and the screen playback window, respectively (S143).

As such, when the digital content generated according to the present invention is executed, the media file and the screen file are respectively decoded and output separately. Therefore, two screens are required for a user who uses the content to view the contents.

In this regard, when there is only one display screen of the user terminals 137 and 138, the content reproduction tool 139-1 may display a media play window 155-152 on the display screen 151 as shown in FIG. 15A according to a user's selection. 1) and the screen play window 155-2 may appear, or one of the media play window 155-1 and the screen play window 155-2 may be minimized as shown in FIG. 15B. .
