VSI's Language Learning Control System and Its Control Processing Method

The present invention relates to a language learning means through automatic repetition of a specific section in a video cassette recorder system (hereinafter referred to as VCR) system, which is particularly applicable to audiovisual language learning through VSI tape playback. When the mode is switched to, the audio output of the part is automatically repeated, so that the repeated video output can be heard visually along with the video screen to achieve effective language learning.

The VSI system is a device to record, play back and view the video / audio signals provided from various video sources (video camera, cable broadcasting, air broadcasting, etc.). A section automatic repeat reproducing means is known.

Such means are known from Korean Patent Publication No. 1994-4561, 1994-1082, and Patent Publication No. 94-1277.

They mainly skip the sections that are not set based on the sections that the user sets a lot, so that the user can watch the video / audio signals recorded in the specific sections.

Among them, the contents of the published Patent Publication No. 1994-4561 are shown as FIG. 1.

Herein, a key portion 41 for providing various command inputs to the system microcomputer 42 and an operation set in the built-in program memory 48 by recognizing a user's selection or an abnormal state inside the key input portion 41 or The system microcomputer 42 which performs the whole operation by the process of progression, the capstan drive system 43 of capstan pulse generation which calculates the amount of tape movement, moving a tape at constant speed under the control of this microcomputer 42, and The servo drive system 45 for controlling the running and the capstan drive system 43 temporarily store the count value of the capstan pulse in the capstan drive system 43 from the time of reproduction, store it in the memory 48, read it out as necessary, and provide it to the microcomputer 42. It consists of the structure containing the register 46, the tape drive deck drive system 44, etc.

In such a conventional system, as shown in FIG. 2, it is checked whether the system is powered on (step 200). If it is powered on, it is checked whether the play button is on (step 201). Step 202).

After that, the count value of the capstan output is stored (step 203) and the input of the auto repeat button is checked (step 204), and if there is a moving distance (step 205), the moving amount is calculated and the automatic rewinding is performed. (Step 207) After performing the regeneration mode (step 208), playback is carried out by the moving distance (step 209), and after that it is checked whether the stop key is on (step 210), and stopped if it is on (step 211). It is made up of.

Therefore, conventionally, a means for automatically searching for a specific section through the above means has been proposed.

On the other hand, the latter technique is similar to the above technique, which means that if a command to perform a multi-part repeat playback mode is input from the keyboard to the microcomputer that controls the general VSI system in the VSI playback mode, the micro computer is turned on. Output the signal to logic 1 and output the down signal to logic 0 to set the up / down counter to the upcount mode, and then check the data in the maximum area number register to determine that no section is set if the data is zero. You tell the user to step on by turning on the settings display.

If the data of the maximum area number register is not zero, the microcomputer initializes the test register to zero and the area address register to 1, increments the data in the test register by one, and outputs a read control signal to start the area 1 of the memory. Data is output through the AND gate and applied to the input terminal Y of the comparator.

At this time, the comparator compares the current reel pulse counting value (X input data) applied from the up / down counter with the input data applied to the input stage, inputs the result into a microcomputer, and stores the result. Increment the data in the address register by one.

Also, the area 1 stop data of the memory is output through the AND gate and applied to the input terminal of the comparator. At this time, the comparator compares the size of the data of the area 1 stop applied to the input terminal and the current reel pulse counting value applied to the input terminal. The comparison result is applied to the microcomputer.

In addition, the microcomputer determines whether the inequality of the counting value area 1 stop at the beginning of the area 1 is satisfied. If the inequality is established, the microcomputer returns to the process of initializing the test register to zero after performing the regeneration mode. Repeats the process after that, and if the inequality of the counting value area 1 stop as of the start of area 1 does not hold, it is not possible to check whether all the intervals have been checked by comparing the data of the test register and the maximum area number register. (Test register data ≠ maximum area number register data), increase the contents of the area address register by 1 (designate the starting point of area 2), increase the contents of the test register by 1, and then the current counting value becomes the starting point of the area 2 and the stopping point. Determine if it is

Perform this operation as much as the data amount of the maximum area number register (the number of setting sections set by the user), and if the current counting value is within several setting sections, play mode is executed. If not, skip the section.

When the playback and the FF mode are executed to the end of the tape and the end of the tape is reached, the microcomputer sets the up / down counter to the down mode and then controls the VSI driving system to perform the rewind mode.

After continuing the rewind mode to the beginning of the tape as described above, at the beginning of the tape, the microcomputer controls the VSI driving system to perform the playback mode. The loop is repeated until an input for canceling the mode is applied.

If the multi-specific section play mode setting key is not inputted to the microcomputer, it is checked whether the multi-specific section play mode setting mode key is inputted from the keyboard. If a specific section repeat play setting mode key is inputted, the section setting mode routine is performed.

That is, in this case, set up / down counter to up mode first, and if there is no area start key input, determine whether it is multi-specific section repeat play setting mode.If there is area start key input, increase the contents of area address register one by one and then write signal. Prints the area start point into memory.

Then, if there is no area stop key input, it is determined whether it is a repetitive playback setting mode for multiple specific sections. If there is an area stop key input, the contents of the area address register are increased by one, and a write signal is output to store the area stop points in the memory.

After increasing the contents of the maximum area number register one by one, it checks whether the repeat play setting mode is in a specific specific section, and returns to the process of checking whether there is an area start key input when the repeat play setting mode is in a specific specific section. The process is repeated, and the process returns to the process of determining whether or not the multi-specific section repeat play setting mode.

As described above, the conventional system suggests a means of automatically repeating a predetermined number of times for a predetermined section, but these are mechanically worn due to system operation because they are able to repeatedly play a predetermined portion by driving a VSI deck. There was a problem in facilitating the aging of the set due to the stiffness and the rapidity of the automatic repetitive motion due to the mechanical action.

In addition, it was difficult to avoid aging or damage to the tape during the frequent movement of the mechanical tape as described above.

An object of the present invention is to improve the problems of the prior art as described above, which can be reproduced by using a semiconductor memory to repeatedly play a particular screen and dialog, as needed, especially when the tape playback in the system By doing so, we can effectively expect language learning in these systems.

The present invention particularly provides a word detection section for detecting words of a speech signal reproduced by the control of a microcomputer connected to the audio system of the system reproducing system so as to realize the object of the above example, and the word initial section of the word detecting section. And an analog converter / digital converter for converting the output of the audio Isis unit to the word data memory, a word data memory for storing the voice digital data provided by the AD converter, and a word data memory under the control of a microcomputer. Dee converter, which digitally / analogs voice digital data and outputs them to a speaker, and microcomputer of a control operation that stores and outputs word data of a specific part in accordance with a word detection key and a still key input provided from a key input unit. VSI of composition Language learning is characterized by the control system.

Another feature of the present invention is to detect the speech word with the screen to be reproduced if there is a word detection key input in the playback mode of the system and to store the word data between the word start and end time in the word data memory, If there is a key input, switch the system to the Still mode and check whether there is a key input by the user, and register the number of user settings in the system memory, and if the number of user settings has been registered, repeat the word randomly from the word data memory. And a language learning control processing method performed by a language learning control processing program including a step of extracting and outputting data.

Figure 3 shows a language learning control system of VSI in accordance with the present invention.

Here, an audio word unit 11 of the system reproduction system is connected to a word detection unit 18 that determines a silent section of a voice signal reproduced by the control of the microcomputer 13 and detects a word. ), The AD converter 14 which detects the silent word initial section of the word detection unit 18 and analog-to-digital converts the output of the audio eye unit 11 to the word data memories 15 and 16. This word converter 14 is connected to word converter memories 15 and 16 which store voice digital data provided therein.

In addition, the output of the word data memories 15 and 16 is digitally / analog-converted to digital output from the word data memories 15 and 16 under the control of the microcomputer 13 to output the speaker 19 to the speaker 19. The converter 17 is connected and is connected to the key input unit 12 so as to store and output word data of a specific part according to the word detection key and the still key input provided from the key input unit 12. The configuration includes a computer 13 and the like.

In the figure, reference numeral AI denotes a reproduction system audio signal input terminal.

On the other hand, the microcomputer 13 or the like is provided with the language learning control processing program 100 of FIG.

In this case, the system detects the voice word along with the screen which is played when the word detection key input is performed in the system play mode, and stores the word data in the word data memory at the word start time. Switching and checking the user's number setting key input to register the number of user settings in the system memory, and if the number of user settings has been registered, extracting and outputting word data that is repeated any number of times from the word data memory. It is included.

In addition, the language learning control processing program 100 checks whether the system is in the playback mode (step 101), executes the playback mode in the playback mode (step 102), and checks whether there is a word detection key input by the user during playback. (Step 103) If present, audio data between the silent section and the silent section is detected from the output of the audio Ish section 11, which is being reproduced, and stored in the data memories 15 and 16 through the AD converter 14 (steps 104 to 16). 108).

Thereafter, the word section data is stored in the data memories 15 and 16 and the user's still key input is checked (step 109). If there is a still key input, the system is executed in the still mode (step 110). Check whether there is a number setting input (step 111), and if there is a number setting, the stored data is fetched from the data memories 15 and 16, and then the stored data is analogized to the speaker 19 by using the converter 17. It outputs (step 113-115).

The system then checks whether the current number of times is the number of user settings (step 116), if it is the number of times of user setting, erases the data stored in the data memories 15 and 16 (step 117), or repeats the output operation until the number of times the user is set. It consists of a series of processes.

In the stem, the data memories 15 and 16 may further include a plurality of data memories 15 and 16 to alternately store and retrieve data in the first and second memories.

In the present invention, when a user wants to repeatedly listen to voice data of a specific screen randomly while watching a language program, the user presses a word detection key of the key input unit 12 as shown in FIG. 3 at a position corresponding to the arbitrary screen. .

When the user presses the word detecting key 12, the microcomputer 13 recognizes this and drives the word detecting unit 18. Then, the word detecting unit 18 detects the silent section output from the audio eye unit 11; This detected signal is then provided to the microcomputer 13.

The microcomputer 13 drives the AD converter 14 according to the word detection signal provided from the word detection unit 18, and the AD converter 14 outputs the voice word signal between the silent sections output from the audio ISI unit 11. To analog / digital conversion and provide its output to the data memories (15, 16).

The data memories 15 and 16 store voice digital signals converted by the AD converter 14 for a predetermined time.

After that, when the user presses the still key, the specific screen is stopped. In this state, when the user sets the number of times for the voice output, the system fetches the voice data from the data memories (15, 16) and converts it to the die converter. When the digital / analog conversion is performed through 17 to output to the speaker 19, the user can hear the voice output repeated several times for a specific screen.

As described above, after the arbitrary number of repeated voice outputs are completed through the data memories 15 and 16, the system automatically erases the contents stored in the data memories 15 and 17. Will be repeated.

Also, a plurality of data memories 15 and 16 are provided to automatically store the next contents in the second memory when the word data capacity stored in the first memory is long when the word data interval on the screen selected by the user is long. This allows flexibility in storing word data.

On the other hand, the above operation is performed by the microcomputer 13 together with the language learning control processing program 100 of FIG. 4, which checks whether the system is in the playback mode, and executes the playback mode if the playback mode is selected. In the meantime, it is checked whether the user inputs a word detection key, and if there is audio data between the silent section and the silent section from the audio ISI section 11 being played, the audio memory 15, 16 is connected through the AD converter 14. In the storage (steps 101 to 108).

Thereafter, the word section data is stored in the data memory (15, 16) to check whether there is a user's still key input. If there is a still key input, the system is run in a still mode. If the number of times is set, the stored data are taken out from the data memories 15 and 16, and then the stored data are analogized through the die converter 17 and output to the speaker 19 (steps 109 to 115).

After that, the system checks whether the current number of times is the user setting number, and if the number of times is set by the user, erases the data stored in the data memories 15 and 16, or repeats the audio output operation until the number of times of the user counting (steps 116 and 117). .

The present invention can improve the problems caused by the mechanical operation of the system because the semiconductor memory means can achieve a voice output repeated a number of times for a particular screen when watching a language learning program using the VSI system, etc. Convenience can also be obtained.
