Description

  The present invention relates to an education system using the Internet, and more particularly to an education system that uses a recordable recording medium and uses the interactive communication function of the Internet.

  Conventionally, CAE (Computer Aided Education) using a CD-ROM in which teaching materials are recorded and a stand-alone personal computer (hereinafter referred to as PC) has been performed.

  In addition, with the spread of the Internet in recent years, an education system that downloads a desired teaching material and uses a home PC has also become popular.

  In addition, with the spread of broadband video transmission functions, instructors will lecture using storage media that contain live video and video, and students will also enjoy an interactive education system that uses a home PC and video camera. I'm starting.

  In the first and second examples described above, a teaching material created in advance is obtained in the form of download via a storage medium or the Internet, and an individual learns offline.

On the other hand, in the third example, the student takes the lecture directly online from the lecturer.
JP-A-11-282826

  However, the above-mentioned conventional systems such as the first and second have a sufficient effect because they take the form of individual learning, lack of tension and concentration in learning, and cannot ask questions. Not.

  On the other hand, in the case of the third example above, interactive lectures are conducted interactively, so there is a sense of tension and concentration in learning, but the contents of the lectures you attended do not remain. Even if it is used, it does not have an effect commensurate with investment.

  The present invention has been made in view of the above, and provides an educational system that exhibits an excellent learning effect by effectively using interactive communication by moving images using the Internet and storage media.

  In order to solve the above problems, the educational system of the present invention is an educational system that performs bidirectional video transmission via the Internet, and includes a lecture recording means for recording video and audio indicating the status of the received lecture, Teaching material recording means for recording the related information related to the teaching material at the time in association with the moving image and the sound recorded by the lecture recording means.

  According to the present invention, interactive video transmission is performed via the Internet, and a lecture scene video and a still image are recorded in association with storage media, thereby increasing the effect of review and providing an effective education system. It became possible to do.

  Moreover, since the teaching material, the lecturer's lecture and the question and answer with the student are recorded on the same medium, it is very convenient for storing and organizing information.

Example 1
FIG. 1 is a block diagram of an education system in an embodiment of the present invention.

  FIG. 2 is an explanatory view showing a display example on the instructor side monitor, and FIG. 3 is an explanatory view showing a display example on the student side monitor.

  FIG. 4 is an explanatory view showing the data arrangement of the write-once medium.

  The operation procedure of the present invention will be described in detail with reference to FIGS.

  First, the operation on the teacher side will be explained. In accordance with the progress of the lecture, the instructor sends a desired text file 2 and / or video file 3 from the teaching materials stored in advance in the storage medium 1 via the media control unit 4 and a storage medium drive unit (not shown). read out. The read data is converted into a format suitable for display on the monitor 7 by the text processing unit 5 and the moving image processing unit 6 (decoded because they are compressed and recorded in the storage medium), and display processing is performed. The images are displayed at predetermined positions on the monitor 7 by the unit 8.

  That is, as shown in FIG. 2, the text teaching material and the moving image teaching material are displayed in a predetermined area of the monitor 7 as necessary.

  On the other hand, the lecture scenery of the instructor himself / herself is input by the camera 9 and the microphone 10, and the compression processing is performed by the encoding processing unit 11 in order to efficiently transmit images and sounds on the Internet. As an example, a moving image is encoded at a low bit rate by the MPEG-4 system.

  In addition, the instructor performs page turning of the text and start / stop of the video according to the progress of the lecture through the media control unit 4.

  Furthermore, the synchronization control unit 12 can scroll the text content or change the text color of the text as the lecture progresses.

  The above lecture content, that is, the entire content in which the moving image teaching material (in a compressed state) and the text teaching material that are progressing in synchronism with the encoded moving image and sound of the instructor itself are added via the transmission processing unit 13. Sent to the Internet.

  Next, the operation on the student side will be described. The data related to the lecture content is separated into data that needs to be decoded and data that does not need to be transmitted by the transmission processing unit 14 on the student side, and is sent to the central control unit 15. That is, the encoded moving image and sound of the instructor who needs decoding, and the moving image teaching material (in a compressed state) that proceeds in synchronization therewith are decoded by the reproduction processing unit 16 and sent back to the central control unit 15. On the other hand, the text teaching material part is sent directly from the central control unit 15 to the display processing unit 17.

  These data are displayed at predetermined positions on the monitor 18 on the student side via the display processing unit 17. That is, as shown in FIG. 3, the live image of the lecturer is added to and displayed on FIG. Accordingly, the student can understand the contents more deeply by watching the moving picture and still picture teaching materials and the facial expressions and explanation contents of the instructor explaining the teaching materials at the same time.

  On the other hand, a camera 18 and a microphone 19 are installed in front of the students, questions about lecture contents are input by the camera and the microphone, and images and sounds are transmitted through the Internet by the encoding processing unit 20, respectively. In order to perform efficiently, compression encoding processing is performed. As an example, a moving image is encoded at a low bit rate by the MPEG-4 system. It is assumed that the video and audio on the student side are displayed on the monitor on the instructor side by the same operation as that on the student side.

  Next, the process of recording the lecture contents on write-once media will be explained.

  In FIG. 4, in the reproduction-only area, a moving image file and a text file having the same contents as those recorded on the storage medium for the instructor are shown in the sector No. indicating the recording position. It is recorded with. These are contents for enabling individual learning without being connected to the Internet.

  The student gives a recording instruction to a drive unit (not shown) of the write-once medium 22 via the media control unit 21 at a point of time when it is considered necessary in accordance with the progress of the above-mentioned attendance. In response to this, the central control unit 15 responds to the recording processing unit 23 with sector NO. In which the encoded video and audio of the instructor and the video file and text file of the teaching material to be explained at that time are recorded. Is sent out. The recording processing unit 23 converts these into a format recordable in a predetermined write-once area of the write-once medium 22 and records it in the corresponding area.

  The above example is shown using FIG. In the reproduction-only area, text files TXT1 and TXT2 are previously stored in sector Nos. At the positions of 001 and 002, the moving image files MOV1 and MOV2 have sector numbers. 101 and 102 are recorded. If the instructor gives an instruction for recording when the instructor is explaining using TXT1, the encoded video and sound (referred to as mov1) of the instructor himself at that time, and the sector NO in which TXT1 is recorded . 001 is recorded in the additional recording area 201.

  Also, if the instructor gives an instruction to record while explaining using TXT2 and MOV2, then the instructor's own encoded video and audio (referred to as mov2) and TXT2 are recorded. Sector No. Sector No. 002 and MOV2 are recorded. 102 is added to the additional recording area 202.

  As described above, the video and audio that the instructor explains at the time when the student gives a recording instruction and the position information of the reproduction-only area of the teaching material used for the explanation are sequentially added to the additional recording area. go.

  Next, a process in which a student learns (reviews) using the above-described added content will be described.

  When the student selects a desired video in the write-once area 24 of the write-once medium 22 via the media control unit 21, that is, the lecture scene of the instructor himself, the sector number of the teaching material file to be explained by the instructor at this time is selected. Is read, followed by sector NO. Is read from the reproduction-only area 25 and stored in the temporary storage unit 26.

  When the student gives an instruction to reproduce the moving image, the reproduction processing unit 16 decodes the instructor's own moving image data from the recordable area 24 and converts it into a format that can be displayed on the monitor 18. The central control unit 15 sends the teaching material file data stored in the temporary storage unit 26 to the display processing unit 17. The display processing unit 17 displays the instructor's own video and teaching material file at a predetermined position on the monitor 18.

  An example is shown in FIG. FIG. 5 shows a case where the instructor's own video mov2 part is played back, corresponding to FIG. The text teaching material TXT2 and the moving image teaching material MOV2 reproduced from the reproduction region 25 are reproduced simultaneously with the instructor's own animation reproduced from the additional recording region 24.

  As described above, while listening to the lecturer's lecture, it is possible to add necessary scenes and related teaching material information to the write-once media, and reproduce them for effective review.

(Example 2)
A second embodiment of the present invention will be described with reference to FIGS.

  FIG. 6 is a data layout diagram on the write-once medium 22 when recording a question and answer scene of a student and a lecturer.

  When a student asks a question with respect to the instructor's explanation and gives a recording instruction via the media control unit 21, the student's question content video and audio file mov2-a are stored in the sector N 0 of the write-once media 22. .203 in the sector NO. Of the moving picture file mov2 of the instructor himself. 202 and recorded.

  FIG. 7 is a display example at the time of review. A student's video reproduced from the additional recording area 24 is displayed on a small screen next to the lecturer's image.

  As a result, a further learning effect can be improved.

  In the above, the reason why the screen content (FIG. 3) of the student is not directly recorded is to avoid deterioration of the image quality of the moving image portion and the text portion of the teaching material. This is also for avoiding a decrease in the additional recording area of the additional recording medium.

  As the storage medium, a read-only CD-ROM can be used, but a recordable or rewritable medium may be used.

  Further, although a CD-R can be used as a write-once medium, other write-once or rewritable media such as a CD-RW, a DVD-R, and a DVD-RW may be used.

  Furthermore, although the above embodiment has been described with a dedicated hardware configuration, the present invention is not limited to this, and can be realized by software (computer program) stored in a storage medium using a general-purpose PC. It is.

  As described in Embodiments 1 and 2 above, according to the present invention, a video of a lecture scene and a still image are recorded in association with the storage medium, thereby increasing the effect of review and an effective education system. It became possible to provide.

  Moreover, since the teaching material, the lecturer's lecture and the question and answer with the student are recorded on the same medium, it is very convenient for storing and organizing information.
