By referring to the information on the position, the storage unit 400 stores the position data of the time point at which the repetitive reproduction key signal is applied. At this time, the position data stored in the storage unit 400 will be the starting point (A) of the repeating section.

Subsequently, when the repetitive playback key signal is applied from the key input unit 100 again, the system controller 200 refers to the information on the current playback position provided from the optical disc player 300 at the time of performing the playback operation. The position data at the time point at which the second repetitive reproducing key signal is applied from 100 is stored in the storage unit 400. At this time, the position data stored in the storage unit 400 will be the end point (B) of the repeating section.

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 A of the repeating section, and the optical disc player 300 is controlled by the system control unit 200. In addition, the program is replayed from the program recorded at the start point A of the repetition section, and information about the current playback position is detected and provided to the system controller 200.

While the optical disc player 300 performs playback from the program recorded at the start point A of the repetition section, the system controller 200 searches whether the repetition release key signal is applied from the key input section 100, and as a result, the key input section When the repetition release key signal is applied from the system 100, the system controller 200 controls the optical disc player 300 to perform normal playback from the time point at which the repetition release key signal is applied, and the optical disc player 300 controls the system. Repeated playback is stopped by the control of the controller 200, and normal playback is performed.

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, so that the current playback position is the end point of the repeating section ( Determining whether it has reached B), and when the current playback position reaches the end point B of the repeating section, the optical disk player 300 is controlled to play back from the start point A of the repeating section, and the optical disk player The control unit 300 replays the program recorded at the start point A of the repetition section under the control of the system controller 200.

In the related art, once a desired section has been set by the above-described method, it can be repeatedly played a predetermined number of times for the set repeat section without a separate key operation.

In the related art, however, it is necessary to set the repetition section in advance, and for the repetition section that has already passed, it has been troublesome to return to the start point of the desired repetition section and set the repetition section.

The system controller 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 system. In particular, when a repetitive playback key signal is applied from the key input unit 100, The counter 500 is controlled to count the time duration of the applied repeat playback key signal.

In addition, the system controller 200 retrieves the information in which the transport distance is compared with the key signal duration in the storage unit 400, and the transport distance corresponding to the duration of the repetitive playback key signal provided from the counter 500. To calculate.

Then, a track spaced apart by a transport distance corresponding to the duration of the search key signal among the track sections where the program has been reproduced is set as the start point A of the repeating section, and a repeat playback key signal is applied from the key input unit 100. The set point is set as the end point B, and the position information about the set repetition section is stored in the storage unit 400. In this case, the position information, that is, the position information on the start point A and the end point B for the repetition section may be time data or an absolute address.

The counter 500 counts the time duration of the repetitive playback key signal applied from the key input unit 100 under the control of the system controller 200, and provides the counted time information to the system controller 200.

The repeated playback method of an optical disc player according to the present invention implemented in hardware including the above-described structural members will be described in detail with reference to FIG.

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 play key signal in response to the user's key operation, and then transmits the generated play key signal to the system controller 200. (S 30)

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 (S40).

If the repetitive playback key signal is applied from the key input unit 100 during the process of step S40 (S50), the system controller 200 controls the counter 500 to count the time for which the search key signal is applied.

The counter 500 counts the duration of the repetitive reproduction key signal applied from the key input unit 100 under the control of the system control unit 200, and provides the counted time information to the system control unit 200. (S 60)

During the above-described steps S50 and S60, the system controller 200 determines whether the repetitive playback key signal applied from the key input unit 100 is stopped (S70), and as a result of the determination, the key input unit ( When the repetitive reproducing key signal continuously applied from 100 is stopped, the counter 500 is controlled to stop the operation of counting the duration of the repetitive reproducing key signal.

The counter 500 stops counting the duration of the search key signal under the control of the system controller 200 (S80).

Subsequently, the system controller 200 searches for information in which the transport distance is compared with the duration of the repetitive regeneration key signal stored and preset in the storage unit 400, and the counter 500 is performed through steps S50 to S80. Calculate the transport distance corresponding to the time information provided from (S90).

The system control unit 200 having completed step S90 sets the point to which the repetitive playback key signal is applied from the key input unit 100 as the end point B of the repetitive playback section in step S50, and reverses from the end point B. In step S90, the track at a position spaced apart by the transport distance calculated in step S90 is set as the start point A of the repeating section (S100). At this time, the track set as the start point A is the optical disc player 300 in step S40. Will be one of the tracks already played.

Thereafter, the system control unit 200 will control the optical disc player 300 to perform repetitive playback for the repetition section set in step S 100, and the optical disc player 300 is controlled by the system control unit 200. Repeated reproduction is performed in the same manner as the above-described conventional technique from the start point A to the end point B of the repeating section set in step 100 (S 110).

In operation S110, the system controller 200 determines whether a repetition release key signal is applied from the key input unit 100 while the optical disc player 300 performs repeat play.

As a result of the determination in step S 110, when the repetition release key signal is applied from the key input unit 100, the system controller 200 controls the optical disc player 300 to stop the repeat play and perform normal play. Then, the optical disc player 300 performs normal playback from the point where the repetition release key signal is applied in step S110 under the control of the system controller 200.

According to the present invention described above, it is possible to set a desired repeating section with only one key operation for a track section that has already been played, and to utilize a repeating playback function, thereby improving the usability of the optical disc player. .
