The present invention relates to a video lecture authoring tool linked to a lecture table of contents and lecture texts, and more specifically, a lecture textbook and a table of contents provided according to the course progress are automatically changed and provided according to the contents of the lecture. Video lecture authoring tool and its authoring method.

Due to the development of information technology, including the Internet, the dissemination of the Internet lecture system, which provides videos via the Internet, is being activated.

Regardless of time and place, the Internet lecture system is in the spotlight because of the advantage that you can watch the lecture you want in any place with internet environment. The trend is developing.

The most basic form of providing video lectures is to record the lecture contents of the lecturer, edit them into images that can be broadcasted over the Internet, and send them to users who have access to the lecture providing site, which the users send to their PCs. It takes a method of receiving and playing back a video to watch a lecture.

However, since this method merely provides lecture videos, users have to purchase and provide lecture texts offline, and have to feel the inconvenience of having to watch the lectures while changing the text pages according to the contents of the lectures.

In order to solve this problem, it provides a video lecture and at the same time create a separate textbook window on the same screen, and simultaneously send video lectures and textbooks, so that users can watch the video lectures at the same time while watching the video textbooks at the same time Is used.

However, even in this case, since the contents of the video lecture and the teaching material are not linked, the user has to manually manipulate the textbook page displayed on the display unit of the PC in accordance with the contents of the lecture.

In addition, since the textbooks provided are not linked to the contents of the lectures, it is difficult to find the pages of the textbooks corresponding to the lectures when the lecture video is played from the middle or moved to a specific position during the lecture viewing. there was.

In addition, in the opposite case, that is, when attempting to watch a lecture on a specific content of a textbook, there was a problem in that the lecture playback position must be changed several times in order to find a corresponding lecture content.

In order to solve these problems, the lecture contents are recorded, the Internet broadcasting file is generated, the textbooks are written according to the lecture contents, and the lecture file and the text file are directly made by using a language for web pages such as HTML and XLM. Coding is also used to link lectures and textbooks.

However, since a person needs to code using a specific language, there is a problem that the linkage between video lectures and textbooks may be inaccurate and time consuming.

In addition, since each file is not configured as a DB, but is simply stored in a separately stored state, a time for searching and transmitting a file from a video providing server was required.

 Therefore, there is a problem that the user waits to receive necessary data from the server, that is, the buffering time is excessively taken.

The present invention is to solve the problems of the prior art as described above, the video lecture authoring tool consisting of a DB linked to the table of contents and lecture texts composed of video lectures and lecture subtitles taken and encoded in real time with a simple operation and its I would like to suggest an authoring method.

This is provided.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the video lecture authoring tool and its providing method linked to the table of contents and lecture teaching materials according to the present invention.

Figure 1 is a block diagram of the composition of the video lecture authoring tool linked to the table of contents, lecture texts according to an embodiment of the present invention.

As shown in FIG. 1, the video contents authoring tool linked with the contents of lectures and teaching materials according to the present invention includes an input / output interface module 122, a main control module 124, a synchronization module 126, and a signal processing module 128. And a DB configuration module 130.

The above-described components are installed in a computer system (hereinafter, referred to as a 'PC') 100 including the input / output devices 106 and 108, the imaging device 102, the microphone 104, and the storage means 110. The functions of each component are briefly described as follows.

The input / output interface module 122 performs data input / output between the main control module 124, the storage means 110, the photographing apparatus 102, the microphone 104, and the input / output devices 106 and 108.

The main control module 124 displays a video lecture authoring window that can control various functions of the authoring tool through an output device (hereinafter, referred to as a display unit) 108 of the PC 100 and an input device 106. Each component of the video lecture authoring tool 120 is controlled according to a signal inputted from) to create a video lecture linked to the contents of the lecture and the textbook.

The signal processing module 128 receives analog image data and audio data input from the photographing device 102 and the microphone 104, generates a video lecture file by encoding according to a specific codec, and stores the video lecture file in the storage means 110. Will be saved.

When the user outputs a synchronization signal using the input device 106, the synchronization module 126 receives the synchronization signal and outputs a video lecture photographing progress time at the time point to the DB configuration module.

In this case, the synchronization signal refers to a signal generated by the user through the input device 106 in order to link the video of the lecture, the contents of the lecture, and the teaching materials during lecture recording.

By setting a specific key of the keyboard, a synchronization signal may be generated when a specific key is pressed, or a synchronization signal may be generated when a specific icon is clicked with a mouse.

The DB configuration module 130 configures the video lecture DB by combining the course title input by the user using the input device 106, the table of contents of the lecture, the teaching image, and the shooting progress time input from the synchronization module 126.

The contents of the lecture by the above-described components and the video lecture creation process linked with the lecture textbook will be described in detail below.

When the user inputs a signal for executing the video lecture authoring tool 120 through the input device 106 such as a mouse or a keyboard, the main module 124 receives the signal and outputs the output of the PC 100. The lecture authoring window for operating the video lecture authoring tool 120 is output through the device (display unit such as a monitor) 108.

The user may view the lecture writing window displayed through the display 108 and select a desired task.

When the user selects a lecture writing menu and clicks the mouse 106, the main module 124 receives a lecture writing request input from the mouse 106 and performs control for creating a lecture.

The main control module 124 generates a window (hereinafter, referred to as a lecture information input window) in which lecture information is input to the display unit 108, and receives lecture information input by the user in the lecture information input window.

Lecture information may be composed of a course name, lecturer name, lecture title, a plurality of lecture contents, and a textbook image corresponding to each lecture contents.

Here, the textbook image is a textbook to be used for lectures, which is a word processor file, a presentation file, or a graphic file created by the instructor through various programs before the video lecture is written, and the storage means 110 or the network of the video-lowering PC 100. Refers to a file stored in the storage means 512 of the video service server 510 connected through the user. At this time, the user writes the textbook image by writing the path and file name where the textbook is stored, and corresponds to the textbook image. It will be linked to the contents of the lecture.

The main module 124 controls the DB configuration module 130 to configure the video lecture DB based on the lecture information input through the lecture information input window, or input data into the pre-designed video lecture DB.

In order to construct a video lecture DB, the present invention proposes two means.

The first means is to use a commercialized DB program, and to design and use a video lecture DB using a commercially available DB program.

First, design a DB by setting tables and fields to be included in a video lecture DB using a DB program.

At this time, the recording progress time field for interlocking the video lecture, the lecture contents, and the teaching materials is designed. The recording progress time field records the current shooting progress time output from the synchronization module 126 to be described later.

Next, the lecture information input window is configured according to the type of information to be recorded in the DB.

That is, the lecture information input through the lecture information input window is designed to match one-to-one with the information stored in the DB.

The main control module 124 outputs the lecture information input through the lecture information input window to the DB configuration module 130, and the DB configuration module 130 which receives the input of the data is inputted to the designed video lecture DB for each item. Enter the video lecture DB to enter.

In this case, the DB configuration module 130 does not perform a function of substantially creating a DB, but inputs and controls data into a pre-configured video lecture DB using a DB program.

The second means is to configure the DB configuration module 130 to generate a table, fields constituting the DB, and input data through the DB configuration module 130.

In other words, rather than constructing a video lecture DB using a DB program, the video lecture DB is designed using the DB configuration module 130 and the input of data recorded in the video lecture DB is controlled.

The DB configuration module 130 may include a table control means 138, a field control means 140, a key value control means 142, and a data input means 144 to perform such a function.

The table control means 138 generates and controls a table constituting the DB according to the control of the main control module 124, and the field control means 140 generates at least one field in the table constituted by the table control means. And control the generated field.

At this time, the generated field specifies the lecture-related information such as the name of the lecture and the name of the lecturer who can specify the lecture, the lecture-related information such as the name of the lecture and the name of the lecture file that can specify the lecture, and a part corresponding to each table of contents. A plurality of fields are generated to store information related to the contents of the lecture, such as the contents of the lecture, the textbook image, and the shooting duration.

Of course, it is also possible to organize each piece of information into a separate table and form a relational database described later.

The key value control means 142 generates and assigns a unique primary key value to the DB configuration record, and the data input means 144 passes through the input device 106 to the field generated by the field control means 140. The lecture information to be input and the shooting progress time input from the synchronization module 126 to be described later are input to the corresponding item of the video lecture DB.

For the method of providing a video lecture linked to the contents of the lecture and the teaching materials using the video lecture DB configured by the video lecture DB and the video lecture authoring tool 120 according to the present invention, refer to the accompanying drawings 2 and 3. To be described later.

After the user inputs all the lecture information through the lecture information input window and makes a lecture video writing request through the input device 106, the main module 124 receives the video writing request and performs the lecture video writing. .

When the instructor starts the lecture, the user clicks the lecture start menu of the lecture authoring window, and the main module 124 receiving the signal controls the signal processing module 128 to control the photographing apparatus 102 and the microphone ( An analog signal input from 104 is encoded.

More preferably, the signal processing module 128 encodes the analog image data input from the photographing apparatus 102 to perform an encoding function, from the image processing means 132 and the microphone 104 to generate a video lecture image file. Voice processing means 134 for generating the video lecture voice file by encoding the input analog voice data, and the video lecture file by combining the video file and the audio file input from the video processing means 132 and the voice processing means 134. It may include a file combining means 136 for generating and storing it in the storage means (110).

While the video is being created, the display unit 108 of the PC 100 displays a plurality of lecture contents inputted in the lecture information input window and textbook images and video recording windows associated with the lecture contents.

While the lecture is being recorded, if the user outputs a synchronization signal through the input device 106 at the time when the lecture content is linked with the new lecture table, the synchronization module 126 receives the synchronization signal and records the shooting progress time at that time. Output to the DB configuration module 130.

The DB configuration module 130 receiving the photographing progress time inputs the photographing progress time into the corresponding data cell of the video lecture DB.

In this case, when the first shooting progress time is input, the DB configuration module 130 inputs the shooting progress time in the shooting progress time field of the second record of the table of the lecture, and sequentially according to the order in which the shooting progress time is input. The record will be changed and entered.

In other words, the first lecture content and the first textbook image will be one record with the shooting time of 00:00 and the second lecture content and the second textbook image will be grouped into the first recording time and one record. In this way, the video lecture DB is composed of the third lecture contents and the third textbook image being combined with the second recording time and one record.

When the lecture recording is completed, the user outputs a lecture completion message to the main module 124 through the input device, and the input main module 124 receives the image generated during the lecture recording process using the file combining means 136. The file and the voice file are combined into one file and stored in the storage means 110, and the video lecture DB configuration of the video lecture is completed.

2 is an exemplary configuration diagram of a relational video lecture DB according to an embodiment of the present invention.

With reference to the accompanying drawings, it will be described in detail a configuration example of the video lecture DB according to the present invention.

Here, relational database (RDB). Refers to a database where data stored in one record can refer to data stored in another record. A relational database can distribute data stored in multiple files and correlate them with each other. Do.

As shown in Figure 2, the video lecture DB is composed of three types of DB.

That is, the course information DB (200), the course information DB (210), the detailed information DB (230), each record data of the DB is configured to refer to the data of the other DB records.

The data values stored in each DB may be set in advance, information input through the lecture information input window may be matched, and input by combining a preset value and information input through the lecture information input window. May be

The course information DB 200 records items for specifying a course, and includes a course code field, a course name field, a lecturer name field, a media server field, a media publication point field, and a media folder field.

The lecture information DB 210 records items for specifying a lecture. The lecture information DB 210 includes a lecture code field, a lecture code field, a lecture order field, a lecture name field, a media file name field, a textbook folder name field, and a player selection field.

Details DB 230 records items that can specify the contents of the lecture of a single lecture, classification code field 232, lecture code field 234, detail item name field 236, textbook image field 238 And a designated time field 240.

Here, the subitem name refers to the name of a specific class of contents constituting the class of contents.

The data value input in the above-described field may be input by the user according to the field, or may be inputted through the lecture information input window and the shooting progress time input from the synchronization module 126. have.

In addition, each DB may refer to a record of another DB by using a data value of a specific record.

That is, by using the data value input in the course code field 202 of the course information DB, a record having the same data value can be referred to the course code field 214 of the course information DB. The record of the detail DB may be referred to as the data value of the field 212, and vice versa.

3 is a diagram illustrating the configuration of a detailed information DB according to an exemplary embodiment of the present invention.

With reference to the accompanying drawings, the configuration of the detailed information DB will be described in detail.

It is the detailed information DB 230 is configured to link the video lecture, lecture materials and lecture contents.

In the detailed information DB 230, a table corresponding to each lecture is generated, and the lecture information DB 210 is referred to each other by using data values stored in the lecture code field.

Each table stores records corresponding to the number of contents in each lecture, and each record has a distinguishing code as a primary key value.

In addition, a field corresponding to the kind of lecture information is formed in the table, and the corresponding data is recorded.

An example configuration of the detailed information DB illustrated in FIG. 3 is an MM1 table 300 of a DB having a lecture code of 'MM1'.

A set of data values bounded by one primary key value is defined as a record. As shown in FIG. 3, the records 314 and 316 respectively include identification code data, lecture code data, detail item name data, textbook image data, and photographing. In this case, a primary key value for specifying a record is input into the division code field 302, and a specific code according to the lecture name or the lecture name is input into the lecture code field 304. In the detailed item name field 306, a specific table of contents of the lecture constituting the lecture is input. In the text image field 308, the path and the text file name of the text file corresponding to the contents of the lecture, the lecture file field 312 is a video lecture. The path and the file name of the video lecture file captured and stored by the authoring means 120 are input.

Here, the teaching material image and the video lecture may be configured to be stored in the storage means 512 of the video service server 510 connected to the PC 100 via the network 502, not the video lecture preparation PC 100.

In this case, the textbook image and video lecture path should include a URL (Uniform Resource Locator) of the video service server.

The case where the PC 100 and the video service server 510 are connected to the network 512 to store the created video and teaching material images and the video DB in the video service server 510 will be described later with reference to FIG. 5. Shall be.

In addition, the current shooting progress time input from the synchronization module 126 is input to the shooting progress time field 310.

The synchronization module 126 outputs the current photographing progress time to the DB configuration module 130 when the user receives a synchronization signal input through the input device 106 during video recording, and receives the DB configuration module ( 130 inputs a photographing progress time into the photographing progress time field 310 of a specific table of the detailed information DB 230.

The shooting progress time is sequentially inputted from the recording progress time field of record 2 in the order of the contents of the lecture, and is linked with the contents of the lecture.

That is, when the first synchronization signal is received, the shooting progress time at that time is recorded in the record (record 2) corresponding to the contents of the second lecture, and when the next reception is received, record 3 (314), and the next time the record It is configured to interlock with pre-entered lecture information in a format recorded in 4.

Shooting progress time, if a video lecture service user watching a video lecture produced by using the video lecture authoring tool 120 according to the present invention, while changing the playback time of the video lecture to any point, the lecture It becomes the reference data that finds and transmits the textbook and the table of contents linked to the playing time.

Therefore, as shown in FIG. 3, the name of this table is defined as MM1, and record 1 314 of the table MM1 300 has a classification code: 0001, lecture code: MM1, lecture contents: Chap1. Introduction, Textbook Image: A.gif, Duration: 00:00, Lecture File: MM1.wmv.

Also, record 3 (316) is divided into code: 0003, lecture code: MM1, and contents: Chap3. Field, Textbook Image: C.gif, Duration: 03:37, Lecture File: MM1.wmv.

The video lecture DB, the video lecture file, and the teaching material image file created in this format are stored in the storage means 110 of the video creation PC 100, and the storage means 512 of the video service server 510 through the network 502. It may be configured to be transmitted to and stored in, and may also be configured to be transmitted to and stored in the storage means 512 of the video service server 510 through the network 502 in real time.

The video lecture service provided by the video service server 510 having the storage means in which the video lecture DB, the video lecture file, and the text image file are configured in this manner is linked to the table of contents and the textbook as follows.

When the video lecture user accesses the web page provided by the video service server 510 connected to the network through the user terminal, the video service server 510 transmits the video lecture viewing page having a plurality of frames to the user terminal. do.

For example, the video lecture watch page may be configured to have three frames, each frame includes a video playback frame for playing a video lecture file transmitted from the video service server 510, a table of contents frame for displaying a table of lectures, Textbook image frame that displays the textbook image corresponding to the table of contents.

Accordingly, the video lecture user terminal reproduces or displays the video lecture file, the table of contents of the lecture, and the teaching material image transmitted from the video service server 510 through each frame.

If the video lecture user changes the playback time of the video lecture to 3 minutes and 40 seconds while watching the video lecture having the lecture code MM1 provided by the video service server 510 through the network, the video service server 510 By receiving the signal, the video lecture and the contents of the lecture and the textbook image linked with the video lecture are transmitted to the terminal of the video lecture user with reference to the video lecture DB 518.

That is, the video service server 510 receiving the playback time change signal finds a table having the lecture code MM1 in the detail DB 230 of the video lecture DB 518, and the shooting progress time is 3 minutes among the records of the MM1 table. The record for 40 seconds will be extracted.

However, as shown in FIG. 3, since there is no record of the shooting progress time being 3 minutes and 40 seconds, the video service server 510 does not exceed the shooting progress time, and the record having the closest shooting time data close to the shooting progress time. Search for and extract.

Accordingly, record 3 316 is extracted, and video service server 510 transmits a table of contents (Chap3. Field) and a textbook image (C.gif) corresponding to the data of record 3, and the playback point of the video lecture file. The data after 3 minutes and 40 seconds will be transmitted by streaming.

Through this process, the video lecture user can be provided with the contents of the lecture and the textbook image linked to the time of playing the lecture.

In the same process, when the user of the video lecture changes the contents of the lecture or changes the textbook image, the video signal is received from the video service server 510 to refer to the video lecture DB 518 to find a corresponding record. The contents of the lecture and the textbook image included in the record are transmitted, and the playback time of the video lecture is adjusted to the data of the shooting progress field and transmitted.

4 is a flowchart sequentially illustrating a method of authoring a video lecture linked to a lecture textbook and a lecture textbook according to an exemplary embodiment of the present invention.

With reference to the accompanying drawings, it will be described in detail the method of authoring video lectures linked to the contents, lecture texts according to the present invention.

When the user executes the video lecture authoring tool 120 installed in the PC 100 (S400), the video lecture authoring tool 120 controls various functions of the authoring tool and creates a video authoring window for creating a video lecture. The display is displayed on the display unit 108 of the PC 100 (S402).

When the user makes a video lecture writing request through the video authoring window, the video lecture authoring tool 120 receives a video lecture writing request (S404), and provides a lecture information input window through the display unit 108 to provide a lecture. Various lecture information received through the information input window is received (S406).

At this time, the included lecture information includes information on data values to be input in various fields that make up a video lecture DB. The name of the lecture, the name of the lecture, the name of the lecturer, the media server, the media publishing point, the media folder, and the contents of the lecture , Video lecture file name, textbook folder name, player selection, detail item name, textbook image file name, and the like.

The video lecture authoring tool 120 receives the lecture information input through the lecture information input window and configures the video lecture DB. If the DB is configured in advance using a commercial DB program, the corresponding lecture information is applied. In the data cell, if the video lecture authoring tool 120 is configured to configure a DB, the table and fields of the DB are set, and the input lecture information is input to the corresponding data cell (S408).

That is, only the data of the shooting progress time field of the video lecture DB is left blank, and the data values of the other fields are input as the lecture information input at this time and the video lecture DB is configured.

After the lecture information input is completed, when the user makes a video lecture writing request, the video lecture authoring tool 120 receives a video lecture writing request and performs a video writing process.

Video lecture authoring tool 120 encodes the analog signal input from the recording device 102 and the microphone 104 connected to the PC 100 to generate a digital video file and a digital audio file (S412).

While the video is being created, the display unit 108 of the PC 100 displays a plurality of lecture contents inputted in the lecture information input window and textbook images and video recording windows associated with the lecture contents.

While the lecture is being recorded, the video lecture authoring tool 120 determines whether a synchronization signal has been received (S414), and when a synchronization signal is received, inputs a shooting progress time at that time into a corresponding data cell of the video lecture DB ( S416).

At this time, the data of the first recording progress time field of the video lecture DB-the first lecture contents and the recording time when the first textbook image and one record-are set to '00: 00 ', and the first When the shooting duration is entered, the data is entered in the shooting duration field of the second record of the lecture table, and the shooting duration time is subsequently inputted after the records are changed in order of input. .

In other words, the first lecture content and the first textbook image will be one record with the shooting time of 00:00 and the second lecture content and the second textbook image will be grouped into the first recording time and one record. In this way, the video lecture DB is composed of the third lecture contents and the third textbook image being combined with the second recording time and one record.

While the lecture is being recorded, the video lecture authoring tool 120 determines whether the lecture finish signal is received (S418), and when the lecture finish signal is received, the video file and the audio file generated during the lecture recording process are one file.
