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

1 is a block diagram showing an embodiment of an automatic repeating and reproducing sound signal according to the present invention. In the apparatus of FIG. 1, first, the sound demodulator 10 receives sound data from an audio recording medium (not shown), receives a control signal from a controller 14 connected in both directions, and demodulates data according to the control signal. Is output to the sound reproducing unit 12. The control unit 14 receives a recording start signal WS, a recording end signal WE, and a repetition frequency setting signal RN by a user's key operation, and read / write signals R / W to the memory 18. ) And the address ADDR. The output terminal of the mode selector 16 is connected to the input terminal of the controller 14 to output the mode signal MD to the controller, and the controller 14 controls the servo circuit to perform a corresponding operation according to a user's command. It is configured to output the servo control signal Break. In addition, the memory 18 is connected to an output terminal of the sound demodulator 10 and an input terminal of the sound reproducing unit 12 so that the sound reproducing unit 12 receives sound data DATA from the sound demodulating unit 10 or the memory 18. It is configured to receive sound and reproduce sound.

The operation of the apparatus of FIG. 1 configured as described above will be described in more detail. First, when a user applies a mode signal MD such as a play mode, a rewind mode, and a screen stop mode to the controller 14 through the mode selector 16, the controller 14 performs an operation corresponding to each mode. Servo control signal (Break) is output to the servo circuit.

First, when the user applies the mode signal MD corresponding to the reproduction mode, the servo circuit (not shown) receives the image and sound signals from the video tape according to the servo control signal Break applied from the controller 14. Operate in the playback mode for playback. At this time, the acoustic data read from the video tape is applied to the acoustic demodulator 10, and the controller 14 controls to demodulate the data into a form suitable for reproducing the sound according to the state of the acoustic data of the acoustic demodulator 10. The signal CTR is applied to the acoustic demodulator 10. The sound demodulator 10 outputs the demodulated data to the sound reproducer 12 according to the control signal CTR, and the sound reproducer 12 reproduces the sound signal. When the video tape is being reproduced as described above, when the user applies the recording start signal WS to repeatedly designate the part to be listened to, the controller 14 sends the write signal W and the recording start address ( ADDR) is applied to allow the currently reproduced sound data to be stored in the memory 18 through the sound demodulator 10. When the user inputs the recording end signal WE to the controller 14, the setting of the sound section to be repeatedly played is completed. If the user does not input the recording end signal WE, the sound repeating section of the memory 18 Since the overflow occurs when the capacity is exceeded, the controller 14 stops writing the memory before the memory 18 overflows. At this time, the user inputs a signal RN for setting the repetition frequency to the control unit 14 to determine the auto-repeating regeneration frequency of the video tape. When the user does not set the repetition frequency, the user automatically sets the repetition frequency.

After setting the sound repeating section as described above, when the user applies the mode signal MD corresponding to the rewind mode to the controller 14 through the mode selector 16, the controller 14 stores the current playback position of the video tape. After that, the servo control signal Break is applied to the servo circuit to perform the rewinding operation up to the beginning of the video tape. At this time, the replay mode is set between the point where the rewind mode signal is generated and the start point of the video tape. While the video tape is rewound by the servo circuit, the control unit 14 applies a read signal R and a recording start address to the memory 18 so that the sound signal between the sound repeating sections is reproduced through the sound reproducing unit 12. do. During the rewind operation, data in the memory is repeatedly output so that the sound signal is continuously reproduced. When the tape rewind is completed, the control unit 14 detects this and stops the output of the read signal R to the memory 18 to stop the sound reproduction and to reproduce the western control signal Break for reproducing the video tape. Will output Accordingly, when the image and the sound of the repetitive playback section are reproduced and are reproduced up to the point where the rewind command has been previously generated, one repetitive playback is performed and the tape rewinding operation is performed again. In this manner, the rewinding and reproducing operations are repeatedly performed as many times as the repetition period for the designated reproducing section, and the sound signal of the reproducing section is reproduced while rewinding the tape.

On the other hand, when the user applies the mode signal MD to the controller 14 to perform the screen stop operation through the mode selector 16, the screen is stopped and the controller 14 reads the signal to the memory 18. The sound between the sound repeating sections is reproduced by the sound reproducing section 12 by applying the R and the address ADDR and repeating the set repetition number RN.

FIG. 2 is a flowchart showing an embodiment of the automatic automatic signal reproduction method according to the present invention. FIG. 2 (a) shows a main program and FIG. 2 (b) shows a sound reproduction routine.

In FIG. 2, it is first determined whether a mode signal has been input (step 101), and if the mode signal is not input as a result of determination, it is terminated, and if the mode signal is input, it is determined whether the input mode signal is a reproduction mode ( Step 102). If it is determined that the playback mode is not in the playback mode, the process ends. In the playback mode, playback of the video tape and the audio signal is started (step 103). While the video tape is being played back, it is continuously checked whether the recording start signal is input (step 104). If no recording start signal is input, the recording is terminated. If the recording start signal is input, the recording start address is applied to the address. Step 105). Then, the sound data is stored in the memory from the address specified in step 105 (step 106) and the value of the address is increased by one (step 107). It is determined whether the overflow occurs because the address exceeds the capacity of the memory (step 108). If an overflow does not occur, it is determined whether a recording end signal is input (step 109). The address value is applied to the recording end address (step 110). If the recording end signal is not input in step 109, the process returns to step 106 and continues to store sound data, and if the recording end signal is input, the address is applied as the recording end signal (step 110). Then, it is determined whether the mode signal is input (step 111). If the mode signal is not input, it is terminated, and if it is input, it is determined whether the repetition setting number is input (step 112). As a result of the determination, if the setting frequency is not input, the setting frequency is set to 1 time (step 113), and then the repetition frequency is set to 0 (step 114). (Step 114). In operation 111, it is determined whether the mode signal inputted is the screen freezing mode (step 115), and if it is not the screen freezing mode, it is determined whether the mode is rewinding mode (step 123). In step 116, the recording start address specified in step 105 is applied to the address (step 117). After reproducing the sound signal corresponding to this address (step 118), the address value is increased by one (step 119), and it is determined whether the increased address value is the same as the recording end address specified in step 110 (step 120). . If it is not the same, go to step 118 to continue playing the sound signal, and if it is the same, increase the number of repetitions by one (step 121). Then, it is determined whether the number of repetitions is equal to the set number of times input in step 112 (step 122). If the same is the same, the process is repeated. If not, the process repeats the process of reproducing the sound repeating section of the memory.

On the other hand, if it is determined in step 123 that the mode signal is not in the rewind mode and ends in the rewind mode, the current video tape is applied to the counter (step 124), and then rewinded to the beginning of the video tape and the sound reproduction loop is executed. (Step 125). The sound reproduction loop is as shown in FIG. 2 (b). In the sound reproduction loop, first, the recording start address designated in step 105 is applied to the address (step 201), and the sound signal corresponding to the address is reproduced (step 202). After the reproduction, the address value is increased by one (step 203), and it is judged whether the rewinding operation of the video tape is completed (step 204). As a result of the determination, when the rewinding operation is completed, the sound reproduction loop is terminated. When the rewinding operation is not completed, it is determined whether the address value increased in step 203 is equal to the recording end address specified in step 110 (step 205). If the result of the determination is not the same, go to step 202 to continue reproducing the sound signal. If the same is the case, when the repetition of the sound repeating section is finished, go to step 201 and repeat the process of replaying the sound repeating section until the rewinding operation is completed. Therefore, in step 125, the sound repeating section in the memory is continuously reproduced while the video tape is rewound to the beginning. After the rewind operation is finished, the number of repetitions is increased by one (step 126), and it is determined whether the increased number of repetitions is equal to the set number of times input in step 112 (step 127). If it is determined that the sound signal automatic repeat reproduction is completed as many times as the preset repetition number, the process is terminated. If not, the video tape is reproduced to the designated part in step 124 (step 128). Thereafter, the process proceeds to step 125 where the sound signal reproduction is performed while the rewinding operation is performed.

As described above, the method and apparatus for reproducing a sound signal according to the present invention repeatedly reproduces a desired part of the screen a predetermined number of times and simultaneously reproduces the sound signal of a specific part designated by the user while rewinding the video tape or during a screen stop state. By reproducing repeatedly, it has the effect of increasing the utilization of time and especially the efficiency of language learning papers.
