Description

Vishial system with automatic repeat playback means by word detection

The present invention relates to a language learning means through automatic repetition of a specific section in a video cassette recorder (hereinafter referred to as a VCR) system, and in particular, So that it is possible to perform language learning and the like effectively in such a system.

The Vishal system is a device that records and reproduces video / audio signals provided by various video sources (video camera, cable broadcasting, airwave broadcasting, etc.). In this Vishial system, An automatic repeat playback means is known.

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

They are mainly designed to allow a user to view a video / audio signal recorded in a specific section by taking an operation of skipping an interval not set based on a plurality of sections set by the user.

Of these, the contents disclosed in the aforementioned Japanese Patent Publication No. 1994-4561 are shown in FIG.

A key unit 41 for providing various command inputs to the system microprocessor 42 and a control unit 42 for recognizing a user's selection through the key input unit 41 or an internal abnormality of the key input unit 41, A system microprocessor 42 for performing overall operations in accordance with the sequence of operations; a capstan drive system 43 for generating a capstan pulse for calculating a tape movement amount while moving the tape constantly under the control of the microprocessor 42; A count value of the capstan pulse is temporarily stored in the capstan drive system 43 from the playback point of time and stored in the memory 48 and read out if necessary and provided to the microprocessor 42 A register 46 and a deck driving system 44 with a tape mounted thereon.

In this conventional system, it is checked whether the system is powered on as shown in FIG. 2 (step 200). If the power is turned on, it is checked whether the playback button is turned on (step 201) Step 202).

Then, it is checked whether or not there is an input of the automatic repeat button (step 204), and it is checked whether or not there is a movement distance (step 205), and if it is counted, the movement amount is calculated and then automatic rewinding is performed (Step 207). After executing the reproduction mode (Step 208), the reproduction is performed by the movement distance (Step 209), and then the stop key is checked (Step 210) .

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

Meanwhile, the latter technique is similar to the above-described technique. When the microprocessor inputs a command from the keyboard to perform multiple specific section repeat play modes in a microprocessor controlling a general Vsial system in a Vsial play mode, Down counter is set to the up-count mode by outputting the signal as logic 1 and the logic 0 as the down signal and the data of the next maximum area number register is checked. If the data is zero, it is judged that no interval setting is made Then you turn on the setting display to notify the user to set the interval.

If the data of the maximum area number register is not zero, the microprocessor initializes the test register to zero, the area address register to "1", then increases the data in the test register by "1" The data of the start of the region 1 is outputted through the AND gate and applied to the input terminal Y of the comparator. Then, the comparator compares the current reel pulse count value (X input data) applied from the up / down counter with the input data applied to the input terminal, inputs the result to the microprocessor and stores the result, Increase 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 compares the data of the "area 1 stop" applied to the input terminal and the current reel pulse count value applied to the input terminal And applies the comparison result to the microprocessor.

Then, the microprocessor judges whether or not the inequality of "start of area 1 <present counting value <area 1 stop" is satisfied, and if the above inequality is established, it is a section set by the user, so after executing the playback mode, the test register is initialized to zero If the inequality of "Start of area 1 <current counting value <area 1 stop" is not satisfied, the test register and the data of the maximum area number register are compared with each other, (Test register data ≠ maximum area number register data) Increase the contents of the area address register by 1 (specify area 2 start point), increase the content of the test register by 1, It is determined whether or not it is within the region 2 starting point and stopping point.

This operation process is performed by the amount of data of the maximum area number register (the number of setting intervals set by the user), and if the current counting value is within the set interval, the playback mode is performed. Skip an interval that does not exist.

If the playback and FF modes are performed to the end of the tape and the end of the tape is reached, the microprocessor sets the up / down counter to the down mode and then controls the Vsial running system to perform the rewind mode.

After the rewind mode is continued to the initial portion of the tape as described above, the microprocessor controls the vise running system to perform the playback mode at the initial portion of the tape. The microprocessor performs the above- Until the input for releasing the mode is applied.

If the microprocessor has not input the multiple specific playback mode key, it is checked whether the multi-specific playback limit setting mode key is input from the keyboard. If the multi-specific playback repeat setting mode key is not input, And if the specific section repeat play setting mode key is input, the interval setting mode routine is performed.

That is, in this case, first, the up / down counter is set to the up mode, and if there is no area start key input, it is determined that the mode is the multiple specific section repeat play setting mode. If the area start key input is made, And stores the area start point in the memory.

If there is no next area stop key input, it is determined whether the mode is a multiple specific section repeat play setting mode. If there is an area stop key input, the content of the area address register is incremented by one and then a write signal is output to store the area stop point in the memory.

The content of the maximum area number register is incremented by one, and then it is checked whether the mode is the multi-specific repeat repeat play setting mode. If the multi-specific repeat repeat play setting mode is selected, And if it is not the multiple-specific-interval repeated playback setting mode, it returns to the process of determining whether it is the multi-specific-interval repeat playback mode.

Thus, in the conventional system, although a means for automatically repeating a certain number of times set by the user is proposed, it has a problem in applying to a system for repeated playback of the word units in a language program or other purposes.

This is because, in the case of performing the automatic repetition operation of the language study by using the above system, the user has to perform the automatic repetition setting work by individually setting the section for every certain phrase section by key operation, And the work for erasing the preset contents when it is necessary to erase them again must be always carried out, so that it is difficult to avoid the inconvenience caused by the troublesome work.

It is an object of the present invention to overcome the problems of the related art as described above, and it is an object of the present invention to provide a method and apparatus for detecting an audio signal by detecting an audio signal in a system and automatically repeating the audio signal by a predetermined number of times So that it can be efficiently used in a system that requires repeated learning and playback of a language learning program or other word.

The present invention particularly provides a system microprocessor for detecting a silent state according to presence / absence of a signal detected from an audio system at the time of tape reproduction and providing the detected silent state to a microcomputer so as to realize the object of the above example, And if there is an output of the silence detection unit, the audio signal is sampled while operating in a rewinding mode, so that the output of the next silence detection unit and the time between silence periods A microcomputer for controlling the microcomputer so as to be able to operate in a stop to play mode when it is judged to be in a stop mode and an audio reproducing section for providing an audio signal to the silence detecting section, It is.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

100: Word detection automatic repeat processing program

FIG. 3 shows a Vishill system having automatic repeat playback means by the word detection according to the present invention.

Here, a silent detection unit 12 detects a silent state according to the presence / absence of a signal detected from the audio playback unit 13 at the time of tape reproduction and provides the detected silent state to the microcomputer, and a rewind mode And if there is an output of the silence detection unit, the audio signal is sampled while operating in a rewinding mode to sample the audio signal, and when it is determined that there is an output of the next silence detection unit and a time between silent periods Mode, and an audio reproducing unit 13 for providing an audio signal to the silence detecting unit.

The system includes a normal counter 16, a register 15, a memory 14, a capstan section 17, a deck section 18, a servo section 19, and the like.

In the present invention, when the user presses the interval repetition key by using the key portion while the user is watching a predetermined language program, the system microcomputer 11 recognizes it as shown in FIG. 3 and transmits it through the deck portion 18 and the servo portion 19 Operate the tape in rewind mode.

At this time, the silence detecting unit 12 detects whether there is a silent section of the audio signal output from the audio reproducing unit 13 in the process of the tape proceeding to the rewind mode, and if the silent interval is provided to the microcomputer 11, 11) registers the ideal state in the register and continues to operate in the rewind mode until the next silence interval is reached.

Thereafter, if there is a silent section detection through the silence detection section 12, it is determined whether the time during the silent section is the time of one word state, and the tape is stopped when it is recognized as one word state.

Thereafter, the system goes from the tape stop mode to the playback mode again and performs automatic repeat playback for one word.

Therefore, the user can accomplish the automatic repetition of a specific section using such a function with one key press.

The above operation is performed by the automatic iterative detection program 100 of FIG. 4, and it is checked whether the system has input of the section repeat key (step 101). If there is a key input, the system performs a rewind mode (Step 102). The signal reproduced by the audio reproducing section 13 is sampled by the silence detecting section 12 to check whether silence is detected (step 103). When silence is detected, the time check counter is cleared 104) again performs the rewind mode (step 105).

Thereafter, the audio sampling through the silence detection unit 12 is performed again to check whether or not the silence of the next section is silenced (step 108). When silence is detected, the number of counts is stored (step 109) and compared with the mute time If the mute time is smaller than the mute time, the process returns to step 106. If the mute time is larger than the mute time, the system is stopped (step 111), and then the reproduction mode is entered (step 112).

When viewing a language learning program or the like using the Vishal system, the present invention performs the automatic repeat playback function in units of words of a specific part of the contents being watched with a single key press, thereby ensuring the convenience of using the system You can.
