A specific part storage and reproducing method of the optical disc reproducing apparatus of the present invention for achieving the above object comprises: a first step of storing time information of at least one or more reproduction start positions according to a user's selection during disc reproducing; A second step of determining whether a play key for accessing the start position stored in the first step is input; In the second step, when the play key is input, a third step of accessing the stored start position and playing the corresponding video is performed.

In another method, a fourth step of storing at least one playback start position and end point according to a user's selection during disc playback; A fifth step of determining whether a play key for accessing the stored start position is input in the fourth step; In the fifth step, when the playback key is input, a sixth step of accessing the stored start position and playing the image up to the end of the start position is performed.

As shown in FIG. 1, a block configuration of an optical disk reproducing apparatus for performing the method comprising the above steps includes a light source for generating light to read data into the optical disk 1 and the optical disk 1; An optical pickup (2) comprising a light receiving portion for receiving a signal reflected from the light; An optical driver 3 for outputting an information signal read from the optical pickup 2 or a signal for searching for a specific position in the optical disk 1 according to a control signal input from a microprocessor to the optical pickup 2 Wow; A microprocessor (4) for analyzing the information signal transmitted from the optical driver (3), extracting time information, and analyzing and processing key signal values input by the user; A key input unit (5) for the user to transmit a key value to the microprocessor (4) using an external operation key; It consists of a playback unit 6 for processing the information signal received from the optical drive unit 3 and converts it into a video signal and an audio signal.

Referring to the operation and effect of the present invention configured as described in detail as follows.

When the user inserts the optical disk 1 of the video into the optical disk player and selects the playback key of the key input section 5, the microprocessor 5 recognizes that the playback key has been selected and sends it to the optical drive section 3. A control signal for reproducing the optical disc 1 is output.

The optical driver 3 then drives the optical pickup 2 to generate an optical signal from the optical pickup 2 to the optical disk 1.

The optical signal thus generated is reflected by the optical disc 1, and the reflected information signal is transmitted to the optical drive unit 3. As shown in FIG.

When the optical driver 3 outputs the information signal to the reproducing section 6, the reproducing section 6 analyzes the information signal, converts it into a video signal and an audio signal, and outputs the converted information signal.

Watch a movie in the same way as above.

At this time, when a scene that the user wants to store comes out, a specific key (hereinafter, abbreviated as memory key) of the key input unit 5 is pressed.

The microprocessor 4 then stores it in its internal memory. The storing method is the starting position of the moment when the memory key is input, and the time information of this starting position, that is, the absolute value of "minute" "second" to the selected number. Store in the appropriate storage location.

For example, when the user wants to store the scene currently being played back in a second storage location (memory), the user presses the memory key and the number key " 2 ".

The microprocessor 4 then stores the absolute values of the time information " minutes "

In the same way as above, the desired part can be stored in the desired location.

If you want to see the part you saved while playing or the video is completely stopped, press a specific key (hereinafter, abbreviated as "recall key") and a number key.

Then, the microprocessor 4 reads the time information from the storage location corresponding to the selected number and outputs a control signal to the optical driver 3 for moving the optical pickup 2 to the corresponding place.

Accordingly, the optical drive unit 3 controls the optical pickup 2 to access and reproduce the starting position.

For example, when you want to replay the screen or song stored at the position "3", press the recall key and the number 3 key through the key input unit 5.

Then, the microprocessor 4 reads information corresponding to a signal input through the key input unit 5 from the internal memory.

The control signal is output to the optical driver 3 in order to move the optical pickup 2 by using the read information.

The optical driver 3 moves the optical pickup 2 to a portion corresponding to the information ("minutes", "seconds") read from the internal memory of the microprocessor 4 to reproduce.

When the optical pickup 2 reproduces a specific portion of the optical disc 1 and outputs an information signal, the optical pickup 2 reproduces the information signal and outputs an audio signal and a video signal.

The user then sees the desired scene again.

If the NEXT key is input while playing the video, the playback operation stops and the user accesses the next stored start position, that is, the start position stored at position 4, and when the NUMBER key is pressed, Play the video by accessing the starting location stored in the storage location corresponding to the number.

As described above with reference to FIG. 2 for the method of storing a specific portion in the process of operating as described above, the microprocessor 4 checks whether the memory key is input among the key signals inputted through the key input unit 5, When entered, check the number key.

As a result of the check, if there is no input of the number key for a predetermined time (for example, 3 seconds), the display returns to the beginning and if the number key "n" is input, the time information of the specific part is stored in the "n" position of the internal memory.

In the same way as described above, the desired scene or the scene that you want to watch again and again is stored repeatedly.

When the user inputs a recall key through the key input unit 5 when the user wants to play a specific part stored by the user during playback or stop state, the microprocessor 4 checks the number key "n" as shown in FIG. .

The portion corresponding to the number key selected by the user is read from the microprocessor internal memory, and then the optical pickup 2 is controlled to read the corresponding portion of the optical disk 1.

This way, when you read the part you want, you'll see it again.

In another embodiment of the present invention, when there is a scene that the user wants to memorize during video reproduction, the start key and the end point are designated using the memory key of the key input unit 5, and then the number key is pressed.

The microprocessor 4 then stores the information corresponding to the start and end points in its storage location corresponding to the number in its internal memory.

In this way, save the desired part in the desired location again and again.

In this state of storage, when the user wants to see the scene again while the video is being played or the video is finished, the user presses the RECALL key and the number key.

Then, the microprocessor 4 reads information from the memory corresponding to the selected number in its internal memory, recognizes the start position and the end position, and then transfers a control signal for moving the optical pickup 2 to the start position. Output to (3).

As a result, the optical driver 3 moves the optical pickup 2 to a position coinciding with the start position so as to reproduce it.

When the reproduced image is played up to the end point, the microprocessor 4 reads the next start position and end point stored in its internal memory and outputs a control signal to the optical driver 3 to reproduce the image. .

Accordingly, the optical driver 3 moves the optical pickup 2 to a position corresponding to the next start position so that the next image is automatically reproduced.

In this way, playback is performed to the end point, and the same operation as described above is repeated to play back the scene stored in the internal memory of the microprocessor 4, unless the arbitrary key such as the stop key is inputted, and the recorded image is continuously played. .

If a NEXT KEY is input while the video is being played, the current playback operation is stopped and the mobile device moves to the next stored location for playback.

With the same function as above, it is also possible to use only as a convenient editing function to find and record / play back only the necessary parts when recording or recording video or audio.

As described above, the present invention provides convenience to the user by storing and playing only moving scenes, music, and scenes that he / she wants to watch again while playing a video disc, and also stores only main scenes and plays them as needed. This has the effect of saving the user time.
