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

1 is a block diagram of hardware for implementing a method of short-term playback of an optical disc player according to the present invention. The key input unit 100, the system control unit 200, the optical disc player 300, the storage unit 400, and the OSD processing unit It consists of 500.

As such, each component member of the hardware for implementing the method for shortening the optical disc player according to the present invention performs the following functions.

First, the key input unit 100 includes a plurality of function keys including a redundant section setting key, a shortcut playback key, a numeric key, and a direction key, and when one of the keys provided as described above is manipulated by a user, A key signal corresponding to the key is generated and provided to the system controller 200.

The system controller 200 controls the overall operation of the optical disc player in response to a key signal generated from the key input unit 100 or various signals input from each component of the optical disc player 300.

The optical disc player 300 performs general operations of the optical disc player such as playback, high speed search, and low speed search by the control of the system controller 200 corresponding to the key signal generated by the key input unit 100.

The storage unit 400 stores data about data about a start point and an end point of a redundant section, a preset speed, a unique number of a disk, and the like.

Hereinafter, a method of shortening and reproducing an optical disc player according to the present invention using the hardware composed of the above-described structural members will be described with reference to FIGS. 2 and 3.

2 is a flowchart illustrating a process of setting an excess section in the method of shortening playback of an optical disc player according to the present invention, and FIG. 3 is a detailed flowchart showing a method of shortening playback of an optical disc player according to the present invention.

First, when an optical disc is loaded in the optical disc player 100 (S 1), the optical disc player reads TOC information of a TOC (Table Of Contents) area allocated to a load-in section of the optical disc, thereby controlling the system controller ( The data is stored in the internal memory (not shown) of the 200 or the storage unit 300 (S 2).

The TOC information read out from the TOC area may also include the unique number of the optical disc and the positional information of each track.

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 and provides the generated key signal to the system controller 200 (S 3).

The system control unit 200 receiving the play key signal from the key input unit 100 controls the optical disc player to play the optical disc mounted in the optical disc player 300, and the optical disc player 300 is controlled by the system control unit 200. ) Reads the predetermined information contained in the mounted optical disc and provides the system controller 200 with the position information of the optical disc which is currently reading the information. (S 4)

In step S4, when the user manipulates the redundant section setting key provided in the key input unit 100 to set the redundant section, the key input unit 100 generates a redundant section setting key signal to generate the system control unit 200. Provided to (S 5). In this case, the excess section may be a section in which the user feels bored or unnecessarily feels unnecessary to watch / listen, or may be a section other than the section that the user wants to watch again.

The system controller 200 receiving the surplus section setting key signal from the key input unit 100 stores the position information of the optical disc at the moment when the surplus section setting key signal is applied to the storage unit 400 as a start point of the surplus section (S6). ). At this time, the optical disc player 300 continues to maintain the playback operation. Further, the position information of the start point of the surplus section will be stored together with the unique number read out in step S2.

Subsequently, when the excess section release key signal is generated again from the key input unit 100 by the user's key manipulation (S7), the system controller 200 recognizes the excess section release key signal and generates the excess section release key signal. The positional information of the optical disc at the point to be stored is stored in the storage unit 400 as an end point of the surplus section (S 8). In this case, the position information on the end point of the redundant section may be stored together with the unique number of the optical disk and the position information on the start point of the redundant section in step S6.

Thereafter, the above-described steps S4 to S8 are repeated until the stop key signal is generated from the key input unit 100, and if the stop key signal is generated from the key input unit 100 (S 9), the system controller The control unit 200 controls the optical disc player 300 to stop the reproduction, and the optical disc player 300 stops the reproduction operation under the control of the system controller 200 (S 10).

The process of setting the excess section is as described above, and a method of short-playing an optical disc in which the excess section is set by the above-described process will be described.

First, when a predetermined optical disc is loaded into the optical disc player (S 101), the optical disc player 300 reads TOC information from the TOC area allocated to the load-in section of the optical disc, thereby saving internal memory (not shown) in the system control unit 200. Or the TOC information in the storage unit 400 (S 102). At this time, by reading the TOC information, the system controller 200 recognizes the unique number and track information of the optical disc.

Subsequently, when a user manipulates a short play key provided in the key input unit 100 to short-play the optical disc mounted on the optical disc player 300, the key input unit 100 generates a short play key signal to generate a system control unit ( 200) (S 103).

In step S13, the system controller 200 to which the short play key signal is applied searches for the storage unit 400 and searches whether data for the excess section corresponding to the unique number of the optical disc recognized in step S102 is stored. (S 104)

As a result of the search in step S104, if the storage unit 400 does not have information on the excess section corresponding to the unique number of the optical disc, the optical disc player 300 is controlled to play back all the data contained in the optical disc, and the optical disc player 300 reproduces the mounted optical disc under the control of the system controller 200 (S 111).

On the other hand, if the search result of step S104, the storage unit 400 has information on the excess section corresponding to the unique number of the optical disk, the system control unit 200 withdraws the data for the excess section from the storage unit 400 (S 105) In this case, the data for the excess section will include the position data for the start point and the end point of the excess section. At this time, the position data for the start point and the end point of the surplus section will be made by the time data provided to the system controller 200 to inform the position of the disc currently being played by the optical disc player 300 when the optical disc is played.

The system controller 200 performs step S 105 and at the same time controls the optical disc player 300 to perform the playback operation of the optical disc, and retrieves the current playback position of the optical disc. At this time, the optical disc player 300 performs the reproducing operation of the optical disc under the control of the system control unit 200 and simultaneously provides the system control unit 200 with the position information of the optical disc currently being reproduced. Will retrieve the current playback position. (S 106)

In step S 106, the system control unit 200 compares the start point of the redundant section drawn out in step S 105 with the playback position of the current optical disc (S 107), and as a result of the comparison, the current playback position of the optical disc is drawn out in step S 15. If it coincides with the start point of the surplus section, the system controller 200 controls the optical disc player 300 to play from the end point of the surplus section drawn out in step S105 by referring to the TOC information read out in step S2, and the optical disc player. The control unit 300 starts playback from the end point of the surplus section under the control of the system controller 200 (S 108).

Thereafter, the system controller 200 determines whether there is a next surplus section by referring to the information on the surplus section withdrawn in step S 105 (S109).

As a result of the determination in step S109, if there is a next surplus section, the system controller 200 controls the optical disc player 300 to repeat steps S106 to S109, and if there is no next surplus section, the system controller 200 The optical disc player 300 is controlled to maintain the playback operation of step S 108 until the stop key signal is generated from the key input unit 100.

Subsequently, the optical disc player 300 may repeat steps S 106 to S 109 or perform step S 108 until the stop key signal is generated from the key input unit 100 under the control of the system controller 200. When the stop key signal is generated from the key input unit 100 while the reproduction operation is maintained, the reproduction operation of the optical disc is stopped under the control of the system controller 200 (S 112).

As described above, when the short playback method of the optical disc player according to the present invention is used, only a desired section is played by the user, so that the desired information can be obtained from the optical disc in a short time.
