As shown in FIG. 1, hardware for implementing a repetitive playback method of an optical disc player according to the present invention includes a key input unit 100, a system control unit 200, an optical disc player 300, a storage unit 400, and a counter. 500, and each function thereof is as follows.

First, the key input unit 100 includes a plurality of keys including a play key, a repeat play key, a numeric key, a direction key, and the like, and generates a key signal corresponding to a user's key operation to the system controller 200. to provide.

The system control unit 200 controls the overall optical disc player system in response to signals provided by the key input unit 100 and the respective component members of the optical disc player 300, and particularly, at the current playback position provided by the optical disc player 300. Information and the position information of the repeating section stored in the storage unit 400, and when the playback position of the optical disk player 300 reaches the end point of the repeating section, the optical disk player moves to the start point of the repeating section and plays again. The optical disc player 300 controls the control unit 300 and repeats playback from the start point of the next repetition section with reference to the storage unit 400 when the repetition number of repetitions counted by the counter 500 reaches a preset number. To control.

The optical disc player 300 performs the original operation of the optical disc player 300 under the control of the system controller 200. In particular, when the optical disc player 300 plays or repeats playing a program stored in the mounted optical disc, the optical disc player 300 performs positional information on the playback position. Provided to the system control unit 200.

The storage unit 400 stores the position information of all the repeating sections in which the repeated play is performed, that is, the position information of the start point and the end point of the repeating section, while playing the program recorded on the optical disk. At this time, in the preferred embodiment of the present invention, the time or absolute address is used as the position information for the start point and the end point of the repetition section.

The counter 500 counts the number of times that the optical disc player 300 repeats playback for the repeating section under the control of the system controller 200.

Referring to FIG. 2, a repetitive reproduction method of an optical disc player according to the present invention implemented in hardware including the above-described constituent members will be described.

2 is a detailed flowchart illustrating a repetitive reproduction method of an optical disc player according to the present invention.

First, when a predetermined optical disc is mounted on the optical disc player 300, the system controller 200 controls the optical disc player 300 to load the mounted optical disc, and the optical disc player 300 controls the system control unit 200. The optical disc is loaded under the control of S 10.

When the loading of the optical disc is completed in step S 10, the system controller 200 controls the optical disc player 300 to read the Table of Contents (TOC) information of the mounted optical disc, and the optical disc player 300 controls the system control unit 200. ), The TOC information is read out from the TOC area allocated to the load-in area of the optical disc and provided to the system controller 200. At this time, the TOC information is information stored in the lead-in area of the optical disc at the time of manufacture of the optical disc, and includes the track number for each track of the optical disc, position information about the track start point and the track end point.

The system controller 200 stores the TOC information provided from the optical disc player 300 in an internal memory (not shown) or the storage 400 provided in the system controller 200 itself (S 20).

Subsequently, when the user manipulates the play key provided in the key input unit 100, the key input unit 100 generates a key signal in response to the user's key operation, and then provides the generated play key signal to the system controller 200. do.

The system control unit 200 receiving the play key signal from the key input unit 100 controls the optical disc player 300 so that the optical disc player 300 performs a playback operation, and the optical disc player 300 controls the system of the system control unit 200. By control, the program recorded on the optical disc is read out. In addition, the optical disc player 300 detects a track position on the optical disc currently being reproduced, and provides the system controller 200 with information about the detected current reproduction position (S30).

During the process of step S30, when the repeat playback is performed in a predetermined section of the optical disc by the user (S40), the system control unit 200 performs section information on the repeat section in which the repeat playback is performed, that is, the start point of the repeat section and The location information of the end point is stored in the storage unit 400 (S50). In addition, as the position information on the start point and the end point of the repetition section stored in the storage 400, time data or absolute address data may be used.

If more detailed description to help understand the step S 40 and step S 50 are as follows.

First, if the repetitive playback key signal is applied from the key input unit 100 during the process of step S30, the system controller 200 refers to the information on the current playback position provided from the optical disc player 300 in step S30. In operation S-1, the storage apparatus 400 stores the position data of the time point at which the repetitive reproduction key signal is applied from the key input unit 100. In this case, the position data stored in the storage unit 400 may be a start point A1 of the repeating section.

Subsequently, if the repetitive playback key signal is applied from the key input unit 100 again while the step S30 continues, the system controller 200 returns to the current playback position provided from the optical disc player 300 in step S30. With reference to the information, the position data of the time point at which the second repetitive reproduction key signal is applied from the key input unit 100 is stored in the storage unit 400 (S-2). In this case, the position data stored in the storage unit 400 may be an end point B1 of the repeating section.

On the other hand, in the present invention, by the above-described process S-1 and S-2, the time point to which the first repetitive reproduction signal is applied is set as the start point An of the repetitive reproduction section, and the second repetitive reproduction signal is applied. Although the viewpoint is set as the end point Bn of the repeat playback section, in another embodiment of the present invention, the repeat section is separately operated by operating a selection key provided in the key input unit 100 while displaying information about each track section. You can also set it.

Thereafter, the system control unit 200 controls the optical disc player 300 so that the optical disc player 300 plays back from the start point A1 of the repeating section, and the optical disc player 300 is controlled by the system control unit 200. , The program is played again from the program recorded at the start point A of the repeating section set in step S-1. At this time, the optical disc player 300 detects and provides the information about the current playback position to the system controller 200 as well as playing the program as in step S30. (S-3)

While the S-3 process is in progress, the system controller 200 searches whether the repetition release key signal is applied from the key input unit 100, and as a result, if the repetition release key signal is applied from the key input unit 100, The controller 200 controls the optical disc player 300 to perform normal playback from the time point at which the repeat release key signal is applied, and the optical disc player 300 stops the repeat play under the control of the system control unit 200. , Performs normal playback. (S -4)

However, if the repetition release key signal is not applied from the key input unit 100, the system controller 200 refers to the information on the current playback position provided from the optical disc player 300 in step S-3, so that the current playback position is determined. It is determined whether the end point B1 of the repeating section has been reached, and when the current playback position reaches the end point B1 of the repeating section, the optical disc player 300 can be played back from the start point A of the repeating section again. After the control, the optical disc player 300 performs the process again from step S-3 under the control of the system controller 200 (S-5).

Meanwhile, while steps S40 and S50 are performed, the system controller 200 determines whether the entire repetitive playback key signal is applied from the key input unit 100 (S60), and as a result of the determination, the key input unit 100 is performed. If the entire repetitive playback key signal is not applied, the system control unit 200 controls the entire optical disc player system to repeat the above-described processes S-1 to S-5, and in the optical disc player system, the system control unit 200 By controlling, repeating playback of a plurality of repeating sections through repeating steps S-1 to S-5, the section information is stored in the storage unit 400.

However, as a result of determining in step S 60, when the entire repetitive reproducing key signal is applied from the key input unit 100, the system control unit 200 performs the first repetition period among all the repetitive reproducing sections Rn stored in the storage unit 400. The optical disc player 300 is controlled to perform repetitive playback for the optical disc player 300, while the counter 500 is controlled to count the number of times of the repeated playback in the optical disc player 300.

Under the control of the system controller 200, the optical disc player 300 refers to the section information of the first repetition section stored in the storage unit 400 and starts from the program recorded at the start point A1 of the first repetition section R1. When the playback is started and the playback is completed up to the program recorded at the end point B1 of the first repetition section R1, the playback is again performed from the program recorded at the start point A1 of the first repetition section R1.

In addition, the counter 500 counts the number of times that the optical disc player 300 has repeatedly played the first repetition section R1 under the control of the system controller 200, and counts the counted information in the system controller ( 200) (S 70)

While the above-described step S70 is in progress, the system controller 200 determines whether the stop key signal is applied from the key input unit 100 (S80), and as a result, the stop key signal is applied from the key input unit 100. When the system control unit 200 stops performing the entire repetitive playback of the step S70 or less.

On the other hand, if the stop key signal is not applied as a result of the determination in step S 80, the system controller 200 refers to the information on the number of times of repeat playback provided from the counter 500 in step S 70, and thus, the first repeating period R1. In step S90, the number of repetitions is a numeric key provided in the key input unit 100 during the setting of the repetition section or during the reproducing operation for the repetition section. It may be set separately by an operation such as, may be stored in the storage unit 400 with the interval information when the repetition interval is performed, it may be used to the stored repetition number.

As a result of the determination in step S 90, if the repeated playback has not been performed for the first repetition period R1 for a predetermined number of repetitions, the system control unit 200 performs the entire optical disc player system to continuously perform step S 70 described above. In step S70, the optical disc player system performs the control under the control of the system controller 200.

On the other hand, if it is determined in step S90 that the replay has been repeatedly performed for a predetermined number of repetitions for the first repetition section R1, the system controller 200 determines whether replay for the last repetition section Rn has been performed. (S100), if the repetitive playback has not yet been completed until the final repetition section Rn, the system control unit 200 performs the above steps S70 to S90 for the next repetition section R2. The overall system is controlled, and in the optical disc player system, the above-described steps S70 to S90 are performed by the control of the system controller 200.

On the other hand, as a result of the determination in step S100, if the repeated playback is completed up to the final repeating section Rn through the steps S70 to S90, the entire repeat playback ends.

According to the present invention described above, it is possible to provide a user with a variety of repeat playback function, it is possible to improve the ease of use of the optical disk player.
