Description

VSI system with voice speed control function and its speed control method

The present invention relates to a VXAL VSI and a voice speed control processing method thereof having a voice speed control function to control the voice speed at the time of VSI playback in the VSI with automatic repetitive language learning function, which is particularly the language learning By slowing down the speed of the audio signal that is output during automatic replay of the tape, the user can learn more detailed effects when listening to English conversation.

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 which controls the running, and the capstan drive system 43 temporarily stores the count value of the capstan pulse in the capstan drive system 43 from the time of reproduction, and stores the count value of the capstan pulse in the memory 48 and reads it if necessary and provides it to the microcomputer 42. And a tape drive deck drive system 44.

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

Afterwards, the count value of the capstan output is stored (step 203) and the input of the auto repeat button is checked (step 204). If there is a moving distance (step 205), the moving amount is calculated. (Step 207) After performing the regeneration mode (step 208), playback is carried out by the movement distance (step 209), and then the stop key is checked on (step 210), and stopped (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. Instruct the user to make section settings by turning on the non-setting 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", increases the data in the test register to "1", and outputs a read control signal to the memory. The data of the area 1 start is output through the AND gate and applied to the input terminal Y of the comparator. Then, 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 the microcomputer, stores the result, and then the microcomputer Increment the data in the address register by one.

Then, the area 1 stop data of the memory is outputted through the AND gate and applied to the input terminal of the comparator, where the comparator measures the size of the data of "area 1 stop" applied to the input terminal and the current reel pulse counting value applied to the input terminal. Compare and apply the result to a microcomputer.

In addition, the microcomputer determines whether an inequality of "area 1 start <current counting value <area 1 stop" holds, and if the inequality is established, the user sets the test register to zero after performing the regeneration mode. Return to the initialization process and repeat the process after that, and if the inequality of "area 1 start <current counting value <area 1 stop" is not satisfied, set the intervals by comparing the data of the test register and the maximum area number register. If it is not checked (test register data ≠ maximum area number register data), increase the contents of area address register by 1 (designate area 2 starting point), increase the contents of test register by 1, and then count Determine if the value is within the start point and stop point of area 2.

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.

In addition, the rewind mode is continued to the beginning of the tape, and then 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 releasing 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.

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

However, in the conventional system, a means for automatically repeating a predetermined number of times of a predetermined period set by the user is provided. However, the audio output repeatedly reproduced in a VSI system used for language programs or other purposes is a system for driving a tape. It is related to speed, and because it operates in standard mode, the audio output is always made at a constant speed recorded on the tape. Therefore, the language learner cannot hear the sound when the voice signal is recorded quickly. There was a problem.

In this case, the V-shial deck unit 13 for providing video and audio signals for language learning, the audio deck unit 14 for providing an audio and audio signal, and the video and audio deck units 13 and 14 are driven to drive the system. A microcomputer 12 for management control and a caption processing unit 25 for processing character data output from the audio deck unit 14 and providing the video data to the video processing unit 17 are provided.

In addition, the system includes a key input unit 11 for inputting a control command to the microcomputer 12, and an OSD unit for generating an OSD screen signal under the control of the microcomputer 12 and providing it to the video processing unit 17 ( 23, an audio switch unit 16 for selecting signals output from the video deck and audio deck units 13 and 14 and connecting them to the audio processor 18 and the DMSS unit 24; The video switch unit 22 which selectively connects the output of the caption processing unit 25 and the output of the OSD unit 23 to the video processing unit 17, and is output from the V. deck and audio decks 13 and 14. And a demultiplexer (24) for delaying audio output and providing the audio output to the audio processor (18).

The caption processing unit 25 further includes a data separator 15 for separating caption data from an audio signal output from the audio deck unit 14, and a decoder for decoding caption characters from the caption data separator 15 ( 20), a character memory 19, a die converter 23 for converting digital data into analog, and the like.

The system is equipped with a voice speed adjusting processing program 100 as shown in FIG.

In this case, the system reads the caption data and audio data outputted from the audio deck side if there is an output of the audio deck, and if there is an input of the interval repeat key, the speed of voice output by the DS unit is arbitrarily adjusted during the interval repeat playback. And outputting, and if there is no output on the audio deck side, checking whether there is an output of the Vialal deck unit and performing a Vialal operation.

The voice speed adjustment processing program 100 checks whether the system has an output on the audio deck side (step 101), and if there is an output, reads caption data and audio data output therefrom (steps 102 and 103).

Thereafter, it is checked whether or not the user inputs an interval repeat key (step 104). If so, the section recognition data is read (step 105), and the playback operation is executed (step 106).

It is checked whether there is interval recognition data in the above (step 107), and if there is, the interval memory data is read (step 108), and the audio output is made 0.66 times normal voice output X 0.65 through the super DS unit 24 (step 109). Output (step 110), and if the user repeats the section repeat key input again (step 111), the normal audio output function is performed (step 112).

If there is no output of the audio deck section 14, the output of the V deck deck section 13 is checked (step 113), and if there is an output of the V deck deck section 13, the normal Vial operation is performed. (Step 114) consists of a series of processes.

According to the present invention having the above configuration, as shown in FIG. 3, when the user provides a command for performing a language learning function through the audio deck unit 14 to the microcomputer 12 through the key input unit 11, the microcomputer 12 does this. Recognizes and drives the audio deck 14.

When the audio deck unit 14 is driven, its output is provided to the audio processing unit 18 through the audio switch unit 16, and the audio processing unit 18 outputs the signal to the speaker by amplifying the signal.

If the tape loaded in the audio deck unit 14 is a caption tape, the caption processing unit 25 extracts caption data, generates a text data signal, and provides the video data to the video switch unit 23. In this case, a signal is provided to the video processor 17 to output text data on the TV receiver screen.

In addition, the caption processing unit 25 detects the caption signal mixed in the audio output signal by the data separator 15 and decodes the caption signal with the memory unit 25 by the decoder 20 to generate caption character data, which is then decoded. After the digital / analog conversion through the converter 21 is provided to the video switch unit 22.

On the other hand, when the user presses the section repeat key through the key input unit 11 in the above operation process, the microcomputer 12 recognizes this and proceeds the automatic repeat playback operation of the tape drive of the audio deck unit 14 for an arbitrary section. At this time, the audio audio signal output from the audio deck unit 14 is to provide the audio processing unit 18 with the voice output that is arbitrarily decelerated through the SMS unit 24.

Therefore, the user can adjust the voice output speed through the Super DMS unit 24 when the voice signal speed recorded on the tape is fast or normal or slow when using the system.

In addition, as shown in FIG. 4, the Super DMS unit 24 outputs a signal such as a as a signal b such that the normal audio signal output is about 0.65 times as shown in FIG. 4, so that the user can hear a voice output having a slow voice output speed as needed. Therefore, users who are unfamiliar with language learning can increase the effect of language learning.

In addition, when the system user does not use the audio deck unit 140, the video signal and the audio signal which are reproduced when the V deck unit 130 is driven are passed through the video / audio switch unit 16 and 22 to the video / audio processing unit ( 17 and 18, respectively, so that the user can perform the automatic repetitive reproduction language learning function using the VSI deck (13).

In this case, the OS unit 23 may transmit audio text data to the video screen when the playback operation is performed through the VSI deck unit 13 to perform audiovisual language learning, and on the other hand, the super DMS unit 24 ), You can adjust the voice output speed.

On the other hand, the above operation is performed by the microcomputer 12 in conjunction with the voice speed control processing program 100 as shown in Figure 5, which is also, the voice control processing program 100 is the system of the audio deck side It is checked whether there is an output, and if there is an output, caption data and audio data output therefrom are read (steps 101 to 103).

Thereafter, it is checked whether a user inputs a section repeat key, and if so, the section recognition data is read and a playback operation is executed (steps 104 to 106).

In the above, it is checked whether there is interval recognition data, and if there is, it reads the section memory data, and outputs the speech output through the Super DMS unit 24 by the normal speech output X 0.65 times, and outputs it, and whether the user repeats the section repeat key input again. If it is checked, the normal audio output function is performed (steps 107 to 112).

In addition, when the audio deck unit 14 is not output as described above, it is checked whether there is an output of the Vialal deck unit 13, and when there is an output of the Vialal deck unit 13, the normal Vialal operation is performed. (Step 113, 114).

In the present invention, since the audio output speed can be arbitrarily adjusted when the automatic deck playback function is performed while selectively operating the audio deck and the visual deck in the BCial system, the user can use the limited voice signal speed recorded on the tape. If it is not easy to listen, it can slow down the voice output speed and increase the language learning effect using this system.
