The present invention relates to an automatic return method and an optical regeneration device using the same, and more particularly, to a method for automatically returning to the original regeneration position when a search fails and an optical regeneration device using the same.

An "optical reproducing apparatus" refers to an apparatus for processing data recorded on an optical disc as a reproducible signal and providing the same to the display apparatus, and may include a function of recording data on the optical disc.

Here, an optical disc is a recording medium capable of recording / deleting / rewriting information by optical means. Although CD (Compact Disc) and DVD (Digital Versatile Disc) are most widely used, AOD (Advanced Optical Disc) and BD ( High density optical discs such as Blu-Ray Disc) and HD (High-density Disc) have also been developed.

The optical reproducing apparatus provides a function of reproducing data in consideration of the compatibility between various optical discs as described above.

In addition, if the optical reproducing apparatus receives a search command during the reproduction of the optical disc, it is possible to search for data at another position in the optical disc using the search function.

Examples of the optical reproducing apparatus include a DVD player, a CD player, a DVD / CD all-in-one, a BD / HD all-in-one and the like.

In general, in order to search for the position where the user finds while watching the information recorded on the optical disc through the optical reproducing apparatus, the user moves to the next chapter or title by the user's operation and uses the double speed function. You must search.

Here, the double speed function refers to a function such as fast forward and rewind.

In this case, when moving to another chapter or title due to a user's error, it is inconvenient to use the double speed function again or go to the previous chapter or title and use the double speed function to return to the position where the original user was watching. This follows.

Therefore, when the user fails to search while playing and viewing the information recorded on the optical disc through the optical reproducing apparatus and tries to return to the position where he / she was watching, the technology that can automatically return without the inconvenience of using the double speed function Is requested.

Accordingly, an object of the present invention is to store the positional information in the optical disc at the time when the search command is input when the search command is input during the optical disc playback in order to automatically return to the position where the optical disc was being reproduced without a user's manual operation when the search fails. When the search fails and a cancel command is input, the object is to return to the original playback position by using the previously stored position information.

Method for automatically returning to the original playback position in the search failure according to the present invention for achieving the above object and the optical playback device applying the same, the step of receiving a search command during playback of the optical disk, the position information in the optical disk at the time of receiving the search command Storing the search command, if the cancel command is input within a predetermined time, using the position information in the optical disc at the time of receiving the pre-stored search command, returning the search command to the received position, and playing back from the returned position. It includes a step.

Preferably, the step of receiving a cancellation command, if a cancellation command is not received within a predetermined time, receiving a command other than a cancellation command, performing a command other than the cancellation command, and other than the cancellation command If a cancel command is received while executing the command, the method further includes performing a general cancel function.

More preferably, the step of receiving the cancel command includes performing a general cancel function when a cancel command is input after the predetermined time.

In addition, it is preferable that the predetermined time includes a thing which can be set by a user.

And an input unit for receiving a search command during optical disc reproduction, a memory unit for storing position information in the optical disc at the time when the search command is received, and a cancel command stored in the memory unit if a cancel command is input within a predetermined time. It is preferable to include a control unit for controlling to play back from the returned position by returning to the position where the search command was input using the position information in the optical disk at the time of receipt.

Hereinafter, with reference to the drawings will be described the present invention in more detail.

1 is a block diagram provided to explain an optical reproducing apparatus capable of automatically returning to the original reproducing position when a search fails according to an exemplary embodiment of the present invention.

Referring to FIG. 1, the optical reproducing apparatus 100 includes an input unit 110, a control unit 120, a memory unit 130, an optical disc driver 140, a signal processing unit 150, a reproduction processing unit 160, and an output terminal. 170 is provided. The input unit 110 includes a play button 111, a search button 112, a cancel button 113, and a menu button 114.

The optical reproducing apparatus 100 is equipped with an optical disc 100a.

However, other components that may be included in the optical reproducing apparatus 100 are excluded from the drawings and only those components necessary for describing the present invention will be shown.

The input unit 110 reproduces and searches the optical reproducing apparatus 100 through the play button 111, the search button 112, the cancel button 113, and the menu button 114 provided in the input unit 110. It provides an interface to perform menus and cancel operations.

The play button 111 transmits a command to the controller 120 to play the optical disc 100a mounted on the optical reproducing apparatus 100 by a user's manipulation.

The search button 112 provides an interface for the user to search for information recorded on the optical disc 100a mounted in the optical reproducing apparatus 100.

In addition, when the user presses the search button 112 while the optical disk 100a is being played by the user's play button 111, the search button 112 stops the playback of the optical disk 100a, and the user stops playing the optical disk ( 100a). Detailed description thereof will be described later.

The cancel button 113 provides an interface for canceling when the optical disc 100a is executing a play command, a search command, and a menu command under the control of the controller 120.

In addition, the cancel button 113 may automatically return to the position where the original optical disc 100a was being reproduced when the user failed to search while the optical reproducing apparatus 100 was executing the search command under the control of the control unit 120. Provide an interface. Detailed description thereof will be described later.

The menu button 114 provides the user with an interface for selecting a menu. In addition, the selected menu function may be canceled by a cancel function performed by the operation of the cancel button 113. Here, the cancellation function refers to general cancellation. Detailed description thereof will be described later.

The control unit 120 controls the optical reproducing apparatus 100 as a whole and controls the play button 111, the search button 112, the cancel button 113, and the menu button 114 provided in the input unit 110. It plays a role of performing a user's play command, search command, cancel command, and menu command.

In particular, in the present invention, when the control unit 120 receives a search command from the user through the search button 112 while playing the optical disc 100a mounted in the optical reproducing apparatus 100, the controller 120 receives a search command. Location information in the optical disc 100a of the optical disc 100a is stored in the memory unit 130.

In addition, when the user fails to search for a location to be found, and the controller 120 receives a cancel command from the user through the cancel button 113 within a predetermined time, the controller 120 receives a search command previously stored in the memory 130. Using the positional information on the optical disk at the time point, the control unit returns to the position where the search command is input, and plays back from the returned position.

Here, a predetermined time for receiving a cancel command from the user when the search fails can be set by the user.

Accordingly, in the optical reproducing apparatus 100 to which the present invention is applied, the reproducing position that the user is viewing because the user fails to search while viewing and recording the information recorded on the optical disc 100a through the optical reproducing apparatus 100 is performed. When you try to return to, you can go back automatically without the inconvenience of using the manual speed function.

The memory unit 130 stores location information in the optical disc 100a at the time when a search command is received. In addition, the memory unit 130 provides location information in the optical disc 100a at the time when the search command is input to the controller 120.

The optical disk drive 140 detects data recorded on the optical disk 100a by irradiating the optical disk 100a with light. In other words, the pick up (not shown) of the optical disk drive 140 irradiates the optical disk 100a with light to detect an RF signal from the optical disk 100a.

The signal processor 150 amplifies the RF signal detected by the optical disk drive 140 and converts the RF signal into an electrical signal, and then digitally processes the converted electrical signal.

The reproduction processor 160 decompresses the signal input from the signal processor 150 and processes the signal as a viewable signal.

The output terminal 170 outputs the viewable signal converted by the playback processor 160.

2 is a flowchart provided to explain a method for automatically returning to the original playback position when a search fails according to an embodiment of the present invention.

1 and 2, the control unit 120 receives a search command during reproduction of the optical disc 100a (S211). In other words, while the optical disc 100a mounted on the optical reproducing apparatus 100 is being reproduced under the control of the control unit 120, a search command is received from the user through the search button 112.

The memory unit 130 stores location information in the optical disc at the time when the search command is received (S212). In other words, when the controller 120 receives a search command from the user through the search button 112, the controller 120 stores the location information in the optical disc 100a at the time of receiving the search command in the memory unit 130.

The control unit 120 controls the devices provided in the optical reproducing apparatus 100 to execute the search of the optical disc 100a (S213).

If the user fails to search the searched position (S214), if a cancel command is received within a predetermined time (S215), the user returns to the position where the search command is input by using the location information in the optical disc at the time when the pre-stored search command is received. (S216).

In other words, when the user fails to search for a location to be found, and the control unit 120 receives a cancel command from the user through the cancel button 113 within a predetermined time, the search command pre-stored in the memory unit 130 is input. It returns to the position where the search command was input by using the position information in the optical disc at the time of receiving.

Here, a predetermined time for receiving a cancel command from the user when the search fails can be set by the user.

For example, when the user sets a predetermined time to 5 seconds, if the control unit 120 receives a cancellation command within 5 seconds from the time when the search command is input, the control unit 120 receives a search command previously stored in the memory unit 130. It returns to the position where the search command was input by using the position information in the optical disc at the time point. If the control unit 120 receives a cancel command at the time when 5 seconds have elapsed, the control unit 120 does not perform the cancel function of the present invention and then terminates after performing the general cancel function.

The control unit 120 controls to replay the optical disc 100a from the position returned by the cancel function (S217).

Here, in step S214, when the search for the location that the user finds is successful, the control unit 120 plays back from the location (S217).

In operation S215, when a cancel command is not received within a predetermined time set by the user, when a command other than the cancel command is input (S221), a command other than the cancel command is performed (S222). Here, a command other than the cancel command may be a menu selection command input through the menu button 114, for example.

If a cancel command is received while performing a command other than the cancel command (S223), the general cancel function is performed without performing the cancel function operation of the present invention (S224) and ends. Here, in step S221, if a command other than the cancel command is not input, it means that the command has not been input by the user and ends when the time set by the user has elapsed.

As described above, according to the present invention, when a search command is input during optical disc playback, the position information in the optical disc at the time of receiving the search command is stored, but when the search fails and the cancel command is input, the previously stored position information is stored. By returning to the position which was being played back, the optical disk can be automatically returned to the position where the optical disk was being played back without a user's manual operation when searching failed.

In addition, although the preferred embodiments of the present invention have been shown and described above, the present invention is not limited to the specific embodiments described above, and the technical field to which the present invention pertains without departing from the gist of the present invention as claimed in the claims. Of course, various modifications can be made by those skilled in the art, and such modifications should not be individually understood from the technical spirit or the prospect of the present invention.
