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.

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).

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.

Thereafter, when the user manipulates the play key provided in the key input unit 100, the key input unit 100 generates a play key signal corresponding to the play key and provides it to the system controller 200 (S 30).

The system controller 200 receiving the play key signal from the key input unit 100 will control the optical disk player 300 to play a predetermined program recorded on the optical disk, and the optical disk player 300 controls the system controller 200. The predetermined program recorded on the optical disc is reproduced by the. 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 (S40).

During the process of step S40, when the user manipulates the repeat playback key provided in the key input unit 100, the key input unit 100 generates a repeat playback key signal and provides it to the system controller 200 (S50). The system control 200 receiving the repetitive playback key signal refers to the information on the current playback position provided from the optical disc player 300 in step S40, and stores the position data of the point where the key signal is applied. Store in (S 60). At this time, the position data stored in the storage unit 400 will be the starting point (A) of the repeating section.

Thereafter, when the user manipulates the reproducing key provided in the key input unit 100 again, the key input unit 100 generates a repetitive reproducing key signal and applies it to the system controller 200. (S70)

The system controller 200 receiving the second repetitive reproducing key signal from the key input unit 100 determines that the second repetitive reproducing key signal is the end point setting key signal of the repetition section, The current playback position is stored in the storage unit 400. (S 80)

At this time, in the preferred embodiment of the present invention, the input point of the first repetitive playback key signal is set as the start point of the repeating section, and the input position of the second repeating playback key signal is set as the end point of the repeating section. In an embodiment, the repetition section may be separately set using the key input unit 100 and the OSD processing unit (not shown).

In addition, step S 50 to step S 80 may be performed by stopping the regeneration operation of step S 40, but the exemplary embodiment of the present invention has been described as being performed simultaneously with step S 40.

Thereafter, the system controller 200 controls the optical disc player 300 to play the optical disc player 300 from the start point A of the repeating section, and the optical disc player 300 is controlled by the system control unit 200. , The track jump is performed and is located at the starting point A of the repeating section.

Upon reaching the A position of the optical disc, the optical disc player 300 starts playback from the A position of the optical disc and detects the current reproduction position and provides the system control unit 200 under the control of the system control unit 200. (S 100))

During operation S 100, the system controller 200 detects whether a key signal (repeated reproduction key signal) for setting a small repetition interval is input from the key input unit 100 (S 110).

As a result of the detection of step S 110, if the repetitive reproduction key signal is not input from the key input unit 100, the system controller 200 detects whether the repetition release key signal is input again.

As a result of the determination of S 190, when the repetition release key signal is applied from the key input unit 100, the system control unit 200 controls the optical disc player 300 to play normally from the time point at which the repetition release key signal is applied, and the optical disc player ( 300, under the control of the system controller 200, the operation of performing the repeated playback for the repeated section is stopped and normal playback is performed (S 210).

However, if it is determined in S 190 that the repetition release key signal is not applied from the key input unit 100, the system controller 200 again determines whether the current playback position Tp has reached the end point B of the repetition section. (S 200)

As a result of the determination of S 200, if the current playback position Tp has not reached the end point B of the repeating section, the system control unit 200 controls the entire optical disc player system to repeat from step S 100, and the current playback position ( When Tp) reaches the end point B of the repetition section, the overall optical disc player system is controlled to repeat from step S90.

The overall optical disc player system is controlled from the step S 100 or the step S 90 according to the determination result of step S 200 under the control of the system control unit 200.

On the other hand, if the repetitive playback key signal is applied from the key input unit 100 as a result of the detection of step S 110 described above, the system control unit 200 provides information on the current playback position provided from the optical disc player 300 in step S 100. For reference, the storage unit 400 stores information about the reproduction position at the time when the repetitive reproduction key signal is applied from the key input unit 100. In this case, the time point at which the repetition regeneration key signal is applied will be the start point (a) of the small repetition section.

Thereafter, when the user manipulates the reproducing key provided in the key input unit 100 again, the key input unit 100 generates a repetitive reproducing key signal and applies it to the system control unit 200 (S 130).

The system controller 200 receiving the second repetitive reproducing key signal from the key input unit 100 determines that the second repetitive reproducing key signal is the end point setting key signal of the small repetition section, and The current playback position (b) at the time of input is stored in the storage unit 400 (S 140). At this point, it should be noted that when the small repeating sections a to b are set, the original repeating section is conventionally used. Although A to B are released, the original repeating sections A to B are not released in the present invention.

On the other hand, in the preferred embodiment of the present invention, the setting for the small repeating section is also similar to the original repeating section set in the SS 50 to the S80 step, and the input point of the first repeating playback key signal is defined as the starting point ( a) and the input position of the second repetitive reproduction key signal is set to the end point (b) of the small repetition interval, but in another embodiment of the present invention, the key input unit 100, the OSD processing unit (not shown), and the like. You can also set a small repetition interval separately using.

In addition, the steps S 110 to S 140 may be performed by stopping the regeneration operation of the step S 100, but in the preferred embodiment of the present invention, the operation is performed simultaneously with the step S 100.

Thereafter, the system control unit 200 controls the optical disc player 300 to play the optical disc player 300 from the start point a of the small repetition section, and the optical disc player 300 is controlled by the system control unit 200. In this case, the track jump is performed to be located at the start point a of the repeating section.

The optical disc player 300 having reached the position a of the optical disc starts playback from the position a of the optical disc under the control of the system control unit 200, and simultaneously detects and provides the current playback position to the system control unit 200. (S 160)

During operation S 160, the system controller 200 detects whether a small repetition interval releasing key signal is input from the key input unit 100 (S 170).

As a result of the determination in step S 170, when the small repetition section release key signal is applied from the key input unit 100, the system controller 200 controls the entire optical disc player system to repeat from step S 90 again. That is, the whole optical disc player system is controlled to perform repetitive playback for the original repeating sections A to B. FIG.

On the other hand, if the small repeat section release key signal is not applied from the key input unit 100 as a result of the determination in step S 170, the system controller 200 transmits the current playback position Tp provided from the optical disc player 300 in step S 160. With reference to the information, it is determined whether the current playback position Tp has reached the end point b of the small repetition section (S 180).

As a result of the determination in S 180, if the current playback position Tp has not reached the end point b of the repeating section, the system control unit 200 controls the entire optical disc player system to repeat from step S 160, and the current playback position ( When Tp) reaches the end point b of the repetition section, the overall optical disc player system is controlled to repeat from step S150.

The overall optical disc player system repeats from step S160 or step S150 according to the determination result of step S180 under the control of the system controller 200.

According to the present invention described above, during the repeated playback of the originally set repeat section, when a temporary repeat is desired for the small section within the repeat section, the small section is randomly selected without canceling the original repeat section. Since repeat play can be performed, the usability of the optical disc player can be enhanced.
