Description

Vsyal's sentence auto-repeat control method

The present invention relates to a sentence automatic repeat control method of VSI, which can be performed by using the semiconductor IC (IC) function of the DMS without performing by mechanical operation, especially when performing the automatic sentence repetition function in VSI This is to prevent mechanical burnout of such a system.

The VSI system is a device that records and plays back 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 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. 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", 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.

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.

In addition, the area 1 stop data of the memory is outputted through the AND gate and applied to the input terminal of the comparator. In this case, the comparator measures the size of the "area 1 stop" data 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, it is a user-set interval. If the inequality of "area 1 start <current counting value <area 1 stop" is not satisfied, the intervals set by comparing the data of the test register and the max area number register are compared. If it is not checked by checking whether it is checked (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 increase the current counting value. It is determined whether it is within the start point and stop point of this 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.

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 for automatically repeating a predetermined number of times of a predetermined section set by the user. However, since they are able to repeatedly play a predetermined portion by driving a VSI deck, the mechanical according to the system operation is performed. The problem was to accelerate the aging of the set due to wear and to ensure the automatic repetitive movement due to the mechanical action.

In addition, it was difficult to avoid the tape aging or damage 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 recognizes the number of sentence repetitions and checks whether there is a sentence repetition end key input when checking whether there is an automatic repetition key input so as to realize the object of the above example, and if there is a sentence repetition end key input, V mode including connecting the switch unit to the DMSS unit and driving the DMS, and then checking whether the user set number of times has been reached and operating the system in the regeneration mode when the number of users has been reached. Sial's sentence automatic repetition control method is characterized by.

Hereinafter, more specific features of the present invention will be understood by describing the same in detail with the accompanying drawings.

System circuit related to the present invention is shown as shown in Figure 3 excerpt.

In this case, the DMS unit 12 is connected to the audio reproducing unit 11 of the system reproducing system and converts the audio signal reproduced under the control of the microcomputer 17 to the memory unit 13 and provides the DMS unit 12 to the memory unit 13. The memory unit 13 is connected to the SS unit 12 and stores the audio data corresponding to the section when the microcomputer 17 controls the initial position to the end position of the sentence automatic repeat section.

In addition, the system includes a switch unit 14 controlled by a microcomputer 17, an audio output processing unit 15, a speaker 16, etc., which output audio signals following the output of the switching unit 14, and the like. It is connected.

The system also includes a key input section 19 for inputting various commands, a deck section 18 for system tape drive operation, and the like.

On the other hand, the system is provided with a sentence automatic repeat control program 100 as shown in FIG.

In this case, if it is checked whether there is an automatic repeat key input, recognizing the number of sentence repetition and checking whether there is a sentence repeat end key input (steps 101 to 103). And connecting the units to the DMSS unit and driving the DSs (steps 104 to 106).

In this step, the system checks whether the number of user settings has been reached, and if the number of users has been reached, operating the system in the regeneration mode (steps 107, 108).

According to the present invention, as shown in FIG. 3, when the user presses the play key through the key input unit 19, the tape loaded in the deck unit 18 operates in the play mode, and the audio play unit 11 together with the video program. An audio reproduction output is generated, which provides an audio output AO to the TV receiver side audio input terminal via the switch unit 14.

At this time, in order to listen to the audio automatically repeated by setting a specific section of the video program, the microcomputer 17 sets the beginning and the end of a specific position by using a service function and then plays back the microcomputer 17. The AD unit 12 is controlled to convert the signal output from the audio reproducing unit 11 to store the AD converted digital data in the memory unit 13.

When the microcomputer 17 controls the start and end positions of a specific section, the DMS unit 12 converts the audio data corresponding to the section and stores the converted audio data in the memory unit 13.

Subsequently, when the user presses the automatic repeat play key through the key input unit 19, the microcomputer 17 controls the DMS unit 12 to draw out audio digital data for a predetermined time stored in the memory unit 13. This is converted into an analog signal and then provided to the switch unit 14.

Since the switch unit 14 controls the microcomputer 17 to be connected to the audio output processor 15 in the set, the audio signal passing through the switch unit 14 is amplified by the audio output processor 15 and then the speaker 16. Will be printed).

When there is no audio data output from the DS unit 12 for the number of times of automatic repetition set by the user, the microcomputer 17 extracts the digital data from the memory unit 13 from the beginning, and then converts and performs the above-described method. The same operation will be repeated.

On the other hand, the above operation is performed by the microcomputer 17 in conjunction with the sentence automatic repeat control program 100 as shown in Figure 4, which means that if the system microcomputer 17 checks whether there is an automatic repeat key input in the system The number of sentence repetitions is recognized and it is checked whether there is a sentence repetition end key input (steps 101 to 103).

In the case where the sentence repeat end key is input, the system is placed in the still mode, the switch unit 14 is connected to the DMSS unit, and then the MS is driven (steps 104 to 106).

In this step, the system checks whether the number of user settings has been reached, and if the number of users has been reached, operates the system in the regeneration mode (steps 107, 108).

The present invention enables the system to perform the function by using the SMS when performing the automatic sentence repetition function in VSI, etc. In this system can perform the automatic sentence repetition function by the mechanical driving method according to the mechanical drive Various side effects can be eliminated.
