Description

[Detailed Description of the Invention] The present invention enables learners to easily select and control the content of learning materials consisting of image information and audio information according to their own wishes and level of learning. It concerns educational program materials.

In general, learners themselves determine their learning progress or learning strategy.
A learning method in which the content of teaching materials is selected according to one's preferences is extremely effective in increasing learners' motivation to learn. In other words, rather than simply learning by repeating a series of programs one after another, for example, as you progress through a series of studies, those who have fully understood the content up to that point may be able to move on to more advanced content. There are several different learning processes, such as review for those with insufficient understanding, and there is also a section where learners can choose the content according to their learning progress. Even when learning repeatedly, the first time the learner chooses a course that focuses on the basics, and as the number of repetitions increases, it becomes possible for the learner to choose a course with more advanced content, which significantly improves the learning effect. It becomes possible to give.

Furthermore, questions are set in the middle, and when the learner answers the question, an explanation is given according to the result.
In some cases, once that is completed, you can move on to the next study.

In such cases, since each learner's answer will differ, explanations must be prepared for each answer in the learning materials, and if this is done, the learner will be able to understand the answers they have provided. This allows for extremely efficient learning, such as being able to move on to the next level of learning by simply receiving an explanation. Various other learning states are possible, and the content that the learner should select generally consists of image information and audio information, but it depends on the various learning forms mentioned above. Conventionally, there have been various difficulties in realizing the arbitrary selection of one content according to the purpose at the time from among such teaching materials composed of a large number of image information and audio information using a learning device with a simple configuration. I had a problem.

In other words, the basis of such arbitrary selection of teaching material contents is to prepare a large number of learning materials composed of image information and audio information, and to synchronize multiple learning devices to operate these many learning materials as shown in FIG. However, there are many drawbacks to this method of selecting the contents of teaching materials. The first is that in order to carry out diverse learning, a large number of learning devices are required to reproduce various learning materials, and the second is that the entirety of these many learning devices is time-consuming. If they do not work in unison, the presentation of teaching materials will be confused, so special devices and methods are required to synchronize these many learning devices.The third problem is that the basic functions of learning One of the problems is that the repeated learning operation is extremely difficult. Therefore, it has been desired to develop a learning device that does not have these drawbacks, but in order to develop such a learning device, it is necessary to combine material programs with several contents to be selected into one and create a format that is easy to handle. It is very effective to compose educational programs based on the following. The purpose of the present invention is to solve the problem by eliminating the above-mentioned conventional drawbacks, and to enable learners with various needs to
Using a single learning device with a relatively simple configuration that does not require special control for simultaneous use of a large number of learning devices as in the past, the desired learning content can be selected and extracted at will, or at any time. To provide learning program materials configured so that they can be used repeatedly.

However, in many learning fields, it is known that the image information does not need to be a moving image, and a still image is sufficient.

When such still images are used for learning, static images of several learning material programs, each consisting of several still images, are arranged alternately to form a series of image groups,
The learner can extract the desired image from the group of images and view it. It is necessary to add it to still images. Furthermore, a storage device is required to record the extracted still image and to repeatedly reproduce it until another still image is extracted. In this way, several learning material programs can be configured as a series of image groups, and a desired still image can be separated from the image group and repeatedly reproduced by identifying and extracting the learner. Note that this image transmission technology itself has already been applied to still image broadcasting systems, etc., and is well known. on the other hand,
Regarding the audio information accompanying the learning material, if the learner switches the image information selection switch at any time, generally the previous audio information will also be interrupted and the connection will be discontinuous.

It is clear that the occurrence of discontinuities in audio information in this way is a great hindrance to learning, and it is extremely difficult to prepare learning material programs in advance to avoid such problems. , not practical. Therefore, in the present invention, focusing on this point, only audio information common to all material image programs is handled as audio information of learning materials. In this way, when learning program materials are composed of several types of image programs and audio information common to those image programs, depending on the learning format, learners may The learning effect of freely controlling the process and learning while selecting the desired learning content is very well realized. Furthermore, there are a wide variety of learning types suitable for this type of learning, and the practical effects are extremely large. As described above, the present invention provides learning program materials in the form of a package suitable for selectively controlling and learning learning programs consisting of multiple types of image programs and a single piece of audio information based on the learner's ability. For example, a plurality of frame-based material image signals are repeatedly arranged over an arbitrary section each having a section length of at least one frame, and the material images repeatedly arranged. The sequential material image signals in frame units constituting each of a plurality of sets of material image programs formed by sequentially distributing signals, and the material image signals in the sequential frame unit are respectively disposed in the sequential sections. An identification code signal representing each of the material image programs is attached to a recording position on the recording medium corresponding to the start end, and the image signal recording portion is configured by sequentially recording the material image program. In parallel, an audio signal recording portion is configured by sequentially recording at least a series of material audio signals on the recording medium.

That is, an image in which the period of the image signal is divided into integer multiples including 1 of one screen period of the image signal, and image signal blocks are formed so that the image signal can be recorded so that each can be reproduced separately. The image signals of a plurality of types of image programs are respectively recorded in a recording section, and the time is set such that a single piece of audio information related to the plurality of types of image programs can be presented in synchronization with the presentation of the image information of the image recording section. A plurality of sets of image programs each consisting of a plurality of screens, each set configured according to a specific presentation order, are displayed on an image/audio recording medium in which audio signals are recorded in series, and the screens in each image program are switched. The present invention is characterized in that image information corresponding to the screen after switching at the time of switching is recorded in an image block at a recording position on the image recording unit corresponding to the time point.

The present invention will be described in detail below with reference to the drawings.

First, the principle structure of the learning program material in which multiple types of material image programs are recorded as one on a tape-shaped recording medium and the configuration and arrangement of each information signal on the recording medium are shown in the upper and lower rows of Figure 2. Each is shown below. Therefore, each of the material image programs 4a, 4b, and 4x, which serve as learning materials, is constructed by appropriately repeating a plurality of still image signals and then switching them sequentially. The image signals are alternately combined in large quantities in time-division to form a transmission signal, and are combined and arranged as shown in the lower part of FIG. 2 and recorded on a recording medium.

Here, the standard unit of time interval for each still image signal switching is:
The time of one frame in the current television system (1/
30 seconds) or an integral multiple of the time of one field (1/60 seconds). Therefore, each material image program is
Each still image signal is configured by switching at a time interval that is an arbitrary integral multiple of this unit time. The reference unit for the switching time interval mentioned above is selected as short as one frame at the shortest when it is necessary to set the time of presentation of each image in a program in detail, but in general programs, it is selected as short as 0.5 to 0.
．． It can also be about 6 seconds, that is, about 15 to 18 frames. If the reference unit of the switching time interval is set to a long time interval to such an extent, the recording of image signals on the recording medium at the stage of combining a plurality of material image programs into one like the learning program material according to the present invention will be possible. Also, corrections after compilation can be made by manual operation of the learning program material creation device, which will be described later, and there is an advantage that the operation of each part of the learning program material creation device does not require very high precision. However, if the time delay until the selected image signal is displayed on the receiver becomes a problem, it is desirable to set the reference unit of the switching time interval to be shorter than about 0.2 seconds. All the still image signals in each material image program are recorded in the image signal recording portion 6 on the recording medium 5 only for the above-mentioned unit time from the switching time for each image signal. At this time, a unique image code 7 is added to each still image signal for the material image program to which it belongs. This image code is superimposed on a portion that does not appear on the screen displaying each still image signal, such as a vertical retrace period or a horizontal retrace period, or at the beginning of the above-mentioned unit time in which each still image signal is recorded. Added as a recording signal in the frame. In addition, if the time point of image signal switching is the same between each material image program, for example, A shown in FIG.
2 and B3, the time of switching in one material image program is shifted by a unit time and recorded.
Next, if there is an unrecorded part between the image signal switching times on the recording medium, as shown in parentheses in Figure 2, the unrecorded part is shown in each material program at that time. The image signals along with the respective image codes are repeatedly recorded in an appropriate manner.

The reason why image signals are recorded repeatedly in this way is
When learning while playing back a tape-shaped recording medium running at a constant speed, no matter what time the learner switches to another material image program selected at that time, the program can be played back with only a slight delay. This is to enable the transition to the image of the selected material image program, and this switching mode is extremely important in terms of learning effects. On the other hand, the audio signal recording portion 8 on the recording medium records audio information signals common to each material image program.

Further, a second audio recording portion 9 that is not erased during recording of the image signal is provided on the recording medium 5, and a code indicating the time for each unit time described above is recorded in this recording portion 9. next,
The apparatus for recording study program material on a recording medium according to the present invention described above will be explained with reference to FIG. 3 showing a schematic configuration thereof.

Here, an example will be described in which images of each material image program are recorded one program at a time. As a recording medium,
For example, a magnetic tape such as a cassette video tape is used.

When recording the learning program material, for example, a still image signal of the material image program as shown in the upper part of FIG. 2 and data of the recording time of each image signal are prepared. This recording time data consists of each video switching time and a time at which the image signal should be repeatedly recorded between the switching times. In addition, various types of still image signals to be recorded include still image signals captured by a television camera, output image signals from image signal generators such as character signal generators, and reproduced image signals from video tapes. An image signal is considered. First, the second part in the configuration shown in the third figure.
A generator 1 driven by an oscillation output signal of an oscillator 15 to a second audio recording section 9 on the recording medium via an audio recording section 13.
The unit time signal generated in step 4 is recorded.

This unit time signal is constructed by encoding the recording start position of each still image signal and the number, or address, of the image recording position. Well-known techniques can be applied. Further, this unit time signal can be easily constructed by dividing a burst-shaped sine wave or pulse train of a constant frequency generated every unit time. In this case, it is preferable to insert a portion with a different frequency as a signal indicating a time reference point.
Next, using the unit time signal recorded in the second audio recording section 9 as described above as a reference, the image information signal is recorded for each material image program via the image recording section 11 according to the configuration shown in the lower part of FIG. Recording the audio information signals repeatedly for each time and again via the first audio recording section 12 is as follows.
FIG. 4 shows a more detailed configuration example of an apparatus for recording such image information signals and audio information signals.

That is, the basic aspect of image information signal recording is as follows. The image signal of the first program to be recorded among the plurality of material image programs is output from the image signal section 16.

On the other hand, an image code signal in which the identification number of the material image program is encoded is generated by the image code generation section 17, and is combined with the image signal from the image signal section 16 in the synthesis section 18 and synthesized. Note that in order to superimpose the image code signal on the vertical retrace period of the still image signal, when using a helical scanning video (cassette) tape recorder, switching noise of the magnetic head is superimposed at the position where the image code signal is superimposed. It is effective to select and superimpose scanning lines at positions that do not occur, and to record image code signals using, for example, two scanning lines in order to avoid code errors due to dropouts. For example, simply, the same image code signal is recorded three times across two scanning lines, and upon reproduction, the correct image code is reproduced by majority decision. Next, the recording tape is run, and the image recording position number detection section 21 detects
The number of the image recording position recorded in advance as described above is detected from the second audio recording section, and the comparison circuit 20 compares the recording position number with the data of the image recording time described above. When a predetermined image recording position number for a signal arrives, the gate of the recording control section 19 is opened for a unit time, the image recording section 11 is placed in a recording state, and the still image signal is recorded on a tape.

Note that during the period when the gate of the recording control section 19 is not open, all the recording states described above are canceled. Also,
As the signal recording section 10, a cassette-type video tape recorder is used, which is capable of recording both image and audio signals independently, and is equipped with an electronic editing function that is equipped with a blanking switch and can record cuts. can do. With the above operations, one cut of the material image program has been recorded, and this process is then repeated to complete the recording of the first program.

At this time, it goes without saying that predetermined image information is recorded even during repeated recording in the middle of the image switching time described above.
Further, by returning to the beginning and repeatedly recording other material image programs in the same manner, recording of the image information signal is completed. On the other hand, the audio information signal is recorded in the audio signal recording section 8 on the recording medium 5 via the first audio recording section 12 . In addition,
The unit time signal recorded in the second audio recording section 9 on the recording medium 5 will become unnecessary after recording of each image signal is completed, so the auxiliary audio information signal is recorded in the second audio recording section 9 at the final stage. It is also possible to record at. Next, FIG. 5 shows an example of the basic configuration of a learning device using the above-described learning program material package according to the present invention.

In the configuration shown in FIG. 5, reference numeral 22 denotes a learning material package consisting of an image information signal and an audio information signal, that is, a learning program material according to the present invention, and this learning material package is reproduced by an image/audio reproduction section 23. In the learning material package 22, still image signals of several material image programs to be appropriately selected and learned are distributed and recorded, and each still image signal is assigned an identification number of the respective material image program. Since the images are recorded with unique image code signals shown in the figure, the detection unit 24 detects these image code signals. On the other hand, each learner specifies a desired content, for example, one of a plurality of material image programs, using the keyboard of the selection section 28, and then inputs the identification number of the material image program specified by the learner and the number of the detected image code signal. are compared by the comparison circuit 25, and when the numbers match, the image storage unit 26
A portion of the image signal from the image/audio reproduction section 23, that is, one frame of the desired image signal, is extracted and stored. The image signal thus stored is repeatedly reproduced until the next image signal is recorded and sent to the image display section 27 such as a television monitor for display.
On the other hand, the audio information signal reproduced by the image/audio reproduction section 23 is sent to the audio display section 30, which includes an amplifier, a speaker, earphones, etc., via the audio selection section 29. This operation is performed only when the aforementioned auxiliary audio recording portion is used. In such a case, it is necessary to perform appropriate switching by taking care in the program structure so as not to cause audio discontinuity due to audio switching. As explained above, the present invention enables learning using this method by using a package of learning materials composed of several types of image programs and one type of audio information common to these image programs. This provides enormous practical advantages.

In particular, listening is important in language learning, but conducting only listening without using text at all is likely to result in an incorrect learning style.Learning materials that combine audio information and image information, such as text, It is necessary to use Therefore, it is effective for the image information such as text to be made visible only when necessary and according to the learner's intention. For example, when you occasionally need to look at a text, it takes time and effort to search for a desired image with a text in the form of a regular book, which takes you out of the flow of the conversation. By using the package, you can instantly view the desired image. Therefore, the advantage of the method according to the present invention for transmitting each image information signal of a plurality of material programs so that a desired image can be viewed at any time is extremely large. Since it is necessary to prevent the audio from being discontinuous, it is preferable to use the above-mentioned learning material package format. Also, in hearing practice,
It is often necessary to listen to the same speech over and over again, and if the same image is displayed each time, this will affect the student's motivation to learn, as they will see enough images to see them once. It turns out. Therefore, the learning program material of the present invention is an effective means for solving this problem. That is, there are several types of images, for example,
Images that are not directly related to the content of the speech, images that represent screens that are related to the content of the speech, vocabulary lists that explain only important or difficult words, sentences that display the content of the speech in the original language, speeches They prepare Japanese translations of the content, and compose the images into a series of educational programs that match the flow of the speech. If these images can be switched and viewed at desired times, a completely different learning effect will be brought about than with conventional learning forms. Incidentally, since the time points for selecting and switching images can be arbitrarily combined according to the will of the learner, an extremely large number of learning materials are equivalently prepared. Furthermore, since a series of speeches and other audio information is heard regardless of image switching, the problem of discontinuity in the learning program does not occur, and a natural flow of learning becomes possible. In addition to language learning, there are also various forms of application, such as song lyrics, sheet music, illustrations, photographs, etc., as individual material image programs that can be switched at desired times, or changed each time. Therefore, the learning program material of the present invention has a wide range of uses.

Furthermore, learning program materials that utilize the aforementioned auxiliary audio recording portions are also conceivable.To explain this with respect to the language conversation practice example mentioned above, for example, the main voice of the learning program materials at the position where the learner should speak is The answers are recorded only in the auxiliary audio recording section without any sound, and this auxiliary audio is listened to only when checking pronunciation. On the other hand, the images include a plain color, a drawing showing a conversation scene, a Japanese translation to help think about the original language, and a sentence showing the original language, and the child should choose one of these to practice the conversation. This form of learning is thought to increase interest and significantly increase the effectiveness of learning. The learning program materials of the present invention described above are suitable not only for being played back using learning devices in the form of individual packages, but also for being distributed over a wide range through broadcasting that allows group learning.

That is, the learning program material of the present invention, which consists of a group of many types of images and a series of audio information, can be easily transmitted as a television signal by, for example, transmitting an image code signal superimposed on the vertical retrace interval. I can do it. Further, the television audio multiplexing system, which has already reached the stage of practical use, is a broadcasting system suitable for transmitting auxiliary audio information in the learning program material of the present invention. Furthermore, application to the still image broadcasting system currently under development is also important; the number of programs transmitted in the still image broadcasting system can be extremely large if only image information is considered, but audio information must also be transmitted at the same time. In the past, the number of programs that could be transmitted was limited by the number of audio programs. On the other hand, if the program material according to the present invention is transmitted, there are many types of image information, but only a small amount of audio information is transmitted, making the program much easier to transmit. Therefore, it can be said that the program material of the present invention is a program format that can utilize the transmission system of still image broadcasting extremely effectively. It is clear that the program material of the present invention is suitable not only for broadcasting by radio waves but also for cable television (CATV) by cable transmission.
