[0005]

In the educational video network apparatus according to the first aspect, the teacher can display the video used for the lecture displayed on the personal monitor TV seen by each student and the graph displayed on the presentation monitor TV seen by the students seated side by side. Select an auxiliary image such as a flowchart or a flow chart. The target of the selected image includes a document image such as a notebook placed on the document camera, an image output by an educational personal computer, and a video narp image prepared in advance that is attached to the video recorder. To select an image to be displayed on the personal monitor TV, press the selection switch A on the matrix panel to select an appropriate image, and to select an image to be displayed on the presentation monitor TV, press selection switch B. The image by the selection switch A is displayed on the monitor television A, and the image by the selection switch B is displayed on the monitor television B, so that the teacher can see the image selected by himself. Moreover, the video signal of the selected educational personal computer is converted into an NTSC video signal by the encoder and displayed on the screens of the personal monitor television and the presentation monitor television. Also, the teacher advances the lecture according to the image selected by the selection switch A or the selection switch B,
Of the images, an image that seems to be particularly important is pressed in the freeze switch and stored in the memory as a still image. The teacher can watch the stored image on the monitor televisions C and D.

[0006] The student learns by taking notes and looking at the images on the personal monitor television and the presentation monitor television on which the selected image is displayed. Also,
Each student has different learning progress and sometimes wants to look at the previous image again to deepen their understanding. If the image to be viewed again is a video stored in the memory, the switch for switching the display screen of the personal monitor TV provided on the student side operation panel is pressed, and the still image selected by the freeze switch is viewed. be able to. In addition, the teacher can activate the control device and raise an alternative problem through the image of the personal monitor TV or the presentation monitor TV in order to know the degree of understanding of the students. Each student pushes the answer selection switch on the student side operation panel,
The answer is shown on the monitor TV E provided on the teacher side. Then, the control device judges the selection status of the answer displayed on the monitor TV E, displays the result on the screen and shows it to the teacher. The teacher can grasp the degree of understanding and academic ability of each student based on the selection status of the screen. Further, the teacher can output the selection status on the printer. Further, regarding the attendance status of the students, the attendance status of the students of the control device can be checked and the attendance status of the students can be grasped and output to the printer if necessary. Further, when the failure of each student side input / output device, the means for judging and displaying the failure of the control device is activated to inform the teacher of the failure so that the lecture can proceed smoothly. . In addition, the students can also indicate the failure by displaying a lamp when there is a failure.

The image of the image B (74) which is the image of 5) is displayed. Furthermore, as the lecture progresses, the image A (7
If the image of 3) is judged to be particularly important for learning,
Freeze switch (4) on the matrix panel (27)
0) to store it in the hood memory (30), the monitor TV C (36) is displayed as the previous screen as shown in FIG.
The image of the image A (73) is displayed on. Then, the image A (73) displayed on the monitor television A (34)
9 is changed by placing a document or the like having the image C (75) on the document camera (13) as shown in FIG. Next, if the freeze switch (40) is pressed to store the image C (75) in the hood memory (31) as the previous screen, the image A (73) of the monitor television C (36) is changed as shown in FIG. It becomes the image before the monitor TV D (37), and the image C (7
The image of 5) is displayed on the monitor television C (36) as the previous image. Further, as shown in FIG. 11, when proceeding with a lecture according to specific contents of a book, the book in which the page in which the specific contents are posted is opened is placed on a flat table. The image D (76) of the open page will be shown on the monitor TV A (34) and will also be displayed on the student's personal monitor TV (22).

On the other hand, the student has a personal monitor TV (2
2) Listen to the teacher's lecture and learn while watching the video displayed on the display monitor TV (23). Also,
Since the learning progress of each student is different, I could not understand it well, and the content of the content was changed by the teacher (40).
If the previous or previous screen selected by
Changeover switch (72) on the student side operation panel (24)
Press one of the switches (70) and (71) in front of or before to display the image on the personal monitor TV (22) to deepen the understanding. If you want to return to the content of the lecture currently in progress, press the switch (69) now,
Show the original image. On the other hand, the teacher presses the video switch (41) of the matrix panel (27) as necessary to display the screen display of the personal monitor TV (22) that the student is watching on the monitor TV E (12a),
For too long, the hood memory (30), (3
Personal monitor TV of the student watching the video of (1) (2
Regarding the screen of 2), the controller (12) can be operated to forcibly switch to the screen on which the content of the lecture currently in progress is being broadcast.

Regarding attendance of students, when the attendance switch (44) of the matrix panel (27) is pressed, the seating image in the classroom is displayed on the monitor TV E (12a), and in the case of attendance, the By lighting the image of the seat, the attendance of the student can be grasped. Furthermore,
The teacher can give a three-choice test by using the control device (12) as needed in order to know the progress of the lecture and the degree of understanding of the students. The three-choice test is displayed on the student's personal monitor TV (22), the student sees the problem,
Answer selection switch (68) on the student side operation panel (24)
By pressing any of switches A (65), B (66), and C (67), the result of the answer is shown to the teacher. The teacher presses the answer switch (42) on the matrix panel (27) to learn the correctness or incorrectness of each student's answer on the monitor television E (12a) and to grasp the degree of understanding of the lecture. The student's answer can be changed by pressing a switch different from the switch pressed first, and the control device stores only the switch pressed last, and the monitor television E (1
2a). When performing the next three-choice test, the teacher presses the reset switch (43) of the matrix panel (27) to clear the screen of the monitor television E (12a). By clearing it, it becomes an unanswered state and you can pose the next question. When the three-choice test is completed, the image switch (4
