Reference numeral 214 in FIG. 2 denotes an optical disc.

Referring to Fig. 2, the key signal generation block 202 is a key signal, i.e., a number, corresponding to the operation signal when the user operates or drives a portable CD player via the operation panel 108. By generating a key signal and a function key signal, various key signals generated therein are transmitted to the control block 204.

In addition, the control block 204 includes a microprocessor, for example, which performs overall operation control of the portable CD player, and receives the information when the TOC information is provided from the digital signal processing block 218 to the memory block. In operation 224, when a key signal is input from the key signal generation block 202, a driving control signal corresponding to the key signal is generated and provided to the actuator / motor driving block 208.

Further, the control block 204 controls the display block 224 to display a corresponding identification number and / or a character or the like when performing an operation such as selective reproduction or selective repeat reproduction for each identification number according to the present invention.

Next, the actuator / motor drive block drives the motor 210 and the deck block 212 based on the drive control signal provided from the control block 204 described above, and the deck block 212 is, for example, optical And a pickup device, an actuator drive motor, and the like, and when the optical disc 214 is mounted, index information (additional information or sub code) and sub index of TOC (Table of Contents) for control recorded in the lead-in area of the optical disc Data (i.e., identification number data given in units of words, sentences or pages) is read out and provided to the RF amplifier, server signal processing block 216, and data read from the optical disc 214 in the playback mode (voice audio) Data) to the RF amplifier, server signal processing block 216. At this time, the audio data to be reproduced is data compressed and coded according to, for example, an MPEG algorithm.

In addition, the RF amplifier and servo signal processing block 216 amplifies the RF signals (TOC data and audio / audio data) provided from the deck block 212 to a predetermined predetermined level and provides them to the digital signal processing block 218. The servo control signal obtained from the reproduction output is detected and transmitted to the control block 204. Therefore, the control block 204 controls the tracking servo and the focusing servo using this server control signal.

Next, the digital signal processing block 218 demodulates the RF amplifier, the read TOC information provided from the servo signal processing block 216, the sub data and the audio data, and detects and detects a frame synchronization signal. Error correction is performed, wherein the demodulated TOC information and sub data are provided to the control block 204 and the demodulated audio data is provided to the MPEG decoding block 220.

Meanwhile, the MPEG decoding block 220 restores the encoded reproduction audio signal provided from the digital signal processing block 218 to the original signal before encoding based on the control signal provided from the control block 204, Convert the digital signal into an analog signal, where the converted analog audio signal is provided to an audio signal processing block 222.

In addition, the audio signal processing block 222 processes an analog audio signal provided from the MPEG decoding block 220 (eg, removes noise, amplifies the level, and the like) and delivers the same to the speaker (not shown).

On the other hand, the display block 224 corresponds to the display panel 110 shown in FIG. 1, and the selected identification number is displayed when the identification number is selected for the section selection reproduction, and the volume, tone, and The playback speed is displayed.

Next, a process of performing the reproduction, the interval selection reproduction and the interval selection repeat reproduction of the optical disc according to the present invention using the portable CD player having the above-described configuration will be described.

3 is a flowchart illustrating a process of controlling playback of an optical disc according to an embodiment of the present invention.

Referring to FIG. 3, when recording audio data on a language learning optical disc, an identification number is assigned in units of words, sentences, or pages, and this identification number data is recorded in the lead-in area of the optical disc as additional information ( Step 302). At this time, the teaching material containing the same contents as those recorded on the optical disc is assigned the same identification number as the identification number assigned to the optical disc in words, sentences, or pages.

That is, a method of assigning an identification number to each sentence in the sequence of the first page to the last page of the textbook or assigning a page number to a page number and assigning a serial number to a word or sentence in each page An identification number is recorded in the textbook for language learning, and the identification number is recorded on the optical disc as it is in words, sentences, or pages.

On the other hand, while the portable CD player is in the standby mode (step 304), the control block 204 checks whether or not the optical disc is mounted in the disc mounting unit 104 (step 306), where the result of the check here. When the optical disk is mounted, the control block 204 drives the deck block 212 to read the TOC information and additional information (identification number data) recorded in the lead-in area of the optical disk 214, and then the memory block 206. (Step 308).

Subsequently, in step 310, it is checked whether or not the user has selected playback, and if the playback result is selected here, i.e., when a playback key signal is input from the key signal generation block 202, the control block 204 In operation 312, the deck block 212 is driven to perform a reproduction mode in which the audio data is read from the optical disc 214, that is, the reproduction of the audio signal for language learning (step 312).

On the other hand, in the present invention, a plurality of numeric keys provided on the operation panel 108 when the playback mode or the standby mode is carried out while the optical learning disk (or general optical disk) for language learning is mounted as described above. And the user using the function key and the identification number (word, sentence identification number or page identification number) contained in the textbook as a serial number in units of words, sentences, or pages.

For example, assuming that an identification number is assigned and recorded as a serial number in a sentence unit, select the number 234 to reproduce and output the sentence of track 234 only, or currently play through the advance key operation on the operation panel 108. Section selection playback such as playing back and forth tracks before and after tracks sequentially, or inputting the number 234, the repeat key, and any number N indicating the number of repeats, repeats and outputs the data (voice data) of track 234 N times. Interval repeat selection playback can be performed. In this case, the selected identification number and the number of repetition times are displayed on the display panel 110.

In addition, in the present invention, it is possible to select a section (i.e., a section number 000 to 000) to perform section playback or section repeat playback. For example, the numeric keys 234 on the operation panel 108 can be used. By sequentially setting, setting key, and number key 250, you can perform section selection playback from track 234 to track 250. Then, number key 234, repeat key, set key, number 250, repeat key, number 3 By inputting, the tracks 234 to 250 tracks can be reproduced three times.

Furthermore, in the present invention, only one identification number (i.e., sentence) can be selected and repeated playback can be performed continuously. For example, the voice data of track No. 234 by sequentially inputting the numeric key 234, the repeating key, and the continuous key can be performed. Can be reproduced continuously and repeatedly.

Further, in the present invention, delayed playback can be selected for each word or sentence. For example, if the delay key is pressed at the end of all inputs, the delayed playback is delayed by one track playback output time after the corresponding track is played and output. The next track is played back. If the number 2 is pressed after the delay key is pressed, the corresponding track 1 is played back and output is delayed by two times the playback output of one track.

Meanwhile, in each case described above, information such as an identification number, a character, a repetition number, and the like corresponding to each case are displayed on the display panel 110.

As an example, when the user selects the playback section by pressing number key 234, setting key, and number key 250 (step 314), the corresponding number key signal, setting key signal, and number key from the key signal generation block 202 is selected. Signals are generated in turn and transmitted to the control block 204, which controls the track (i.e. track 234) based on the additional information (i.e., identification number location information) stored in the memory block 206. After controlling the deck block 212 to search for a start position, a section reproducing mode of reproducing tracks 234 to 250 is performed (step 316).

Subsequently, the control block 204 checks whether or not playback up to track 250 has been completed (step 318). If it is determined that playback up to track 250 has been completed, the control block 204 Stops the drive of the deck block 212 to perform the standby mode waiting for the user's selection (step 320).

At this time, as described above, during the playback or section selection playback, the user adjusts the volume, tone, and speed of the voice output through the speaker through the manipulation of the volume key, the voice key, and the speed key as desired. Can be.

Therefore, the present invention, through the selection of a simple identification number using the numeric keys and function keys, the selection playback and selection repeat playback of one sentence or one page, the selection playback and selection repeat playback of the specified section (that is, multiple sentences or multiple pages) In addition, a playback service such as delayed repetitive playback of one sentence unit may be provided.

Meanwhile, in one embodiment of the present invention, an identification number is assigned to an optical disc (ie, a CD) in units of words, sentences, or pages to be used for selective reproduction, but the present invention is not necessarily limited thereto. Those skilled in the art will clearly understand that the same result can be obtained by applying to a storage medium other than an optical disk (for example, a tape or the like).

5 is an external view of a portable CD player according to another embodiment of the present invention. In the portable CD player according to the present embodiment, an edit key, a memory key, an entire memory key, a delete key, and an end button are displayed on an operation panel 508. FIG. It is substantially the same as the portable CD player shown in Fig. 1, except that a key, a mode switching key, and an output key are further provided, and each of the components performs substantially the same function.

Here, the respective function keys added on the operation panel 508 are for use in performing the editing functions (edit mode and edit playback mode) using the portable CD player of the present invention. When editing the contents of an optical disc by the editing method, it is to switch the current mode to the editing mode, and the memory key is for temporarily storing the section identification number input during the editing operation, and the whole memory key is used for normal playback. It is used to save the entire section identification number (word, character or page unit section identification) input in the mode state or the entire section identification number after the previously stored section identification number, and the delete key is input for editing. To delete a section identification number, the section identification number entered immediately before the standby mode, and part of the edits. The end key is used to end the editing operation (post-editing operation and pre-editing operation), and the mode switching key is used to switch between the section identification number input mode and the edit identification number input mode. The output key is for outputting edits.

Here, post-editing refers to an editing method of storing a section of the content as edit information after outputting the voice in the normal playback mode, and pre-editing refers to a desired section using the edit keys and numeric keys without audio output. Means the editing method to save as edit information.

In addition, the structure and respective functions of the drive control system mounted on the portable CD player in this embodiment are substantially the same as or similar to those of the drive control system shown in FIG. Detailed description will be omitted.

On the other hand, the display panel 510, as in the display panel 110 of FIG. 1, displays the selected identification number when selecting the identification number for the section selection playback, and displays the volume, tone in the upper left corner, The current playback speed is displayed in the lower left corner, and the edit information input menu, the disc selection list menu, the identification number selection list menu, and the like are displayed when the post-editing operation, the pre-editing operation, and the edit playback mode are performed.

Next, a process of post-editing the recorded contents of the optical disc using the portable CD player of the present embodiment having the above-described configuration will be described.

FIG. 6 is a flowchart illustrating a process of editing contents of an optical disc in a post-editing manner using a portable CD player according to another exemplary embodiment of the present invention.

Referring to FIG. 6, a user may edit the contents of a voice output section by using a memory key on the operation panel 508 during or after performing a playback mode for reproducing an arbitrary section selected by the user. In step 602, the control block 204 of FIG. 1 checks whether the user has operated the storage key for editing (step 604).

As a result of the check in step 604, when the storage key signal is input, the control block 204 switches the current playback mode to the edit mode (step 606), and the section identification number (i.e., character) of the content currently being played back. Alternatively, the section identification number assigned in units of pages is temporarily stored together with the edit identification number (step 608). At this time, on the display panel 510, assuming that the section identification number of the content currently being reproduced is 510, for example, a menu “Edit 81 510” is displayed. Here, the edit identification number may be the earliest edit identification number which has not yet been used, for example, assuming that the edit area is allocated 01-99.

Subsequently, in steps 610 and 612, it is checked whether a new section identification number or an edit key signal is input while performing the edit mode. 2 is inputted, the control block 204 of FIG. 2 pulls out an edit information input menu having a disc classification item and an edit identification number title item and displays it on the display panel 510 as shown in FIG. 9A as an example. By doing so, a user inputs disc classification and editing identification number title information (step 622).

Here, the disc classification information is information for use in classifying types of CDs mounted in a portable CD player. Such disc classification information may be assigned serial numbers 1 to 10, for example. The serial number assignment for each disc can be arbitrarily set by the user.

Next, when the user inputs the disc classification and editing identification number title information using the numeric keys and the character keys and presses the storage key (step 624), the control block 204 displays the disc classification and editing identification number title information and the section. The identification number is registered in the edit area of the memory block 206 together with the corresponding edit identification number in the edit area of the memory block 206 (step 626).

For example, if the user presses the memory key and the edit key sequentially while playing the section identification number 510, enters the edit information, and then presses the memory key, the section identification number and the edit identification number title information entered by the user are assigned. The editing information registration process is registered in the storage space of the edited edit ID number, and the editing information registration process can be continued until the user presses the end key to switch the edit mode to the standby mode (steps 628 and 630).

In this case, the edit identification number title information of the user input included in the edit information may allow the user to easily distinguish the edit contents stored in the section of the edited contents (that is, the edit identification number section). Character information for the purpose. Therefore, the users can easily know the edit contents corresponding to various situations edited as needed of the entire contents of the disc through the identification number selection list menu provided on the display panel for the user interface.

On the other hand, as a result of the check in step 610, when the user inputs the section identification number (for example, 520) using the numeric keys, the edit playback mode in which the contents of 520 is played is executed (step 614). .

At this time, the user presses the memory key to temporarily store the corresponding section identification number during the edit playback mode of playing the contents corresponding to a certain section identification number (step 616), or the selected section identification numbers by pressing the edit key. The edited content assigned to one edit identification number can be registered (step 618), or the edited content assigned to one edited identification number can be registered to all of the section identification numbers selected and selected by pressing the entire memory key (step 618). 620).

That is, the user may input and reproduce a desired section identification number through steps 608, 610, 614 and 616, and determine whether to edit the content while listening to contents corresponding to the input section identification numbers.

For example, if the section identification number 520 is inputted, the contents of the number 520 are played back and a menu of “Edit 81 510 520” is displayed on the display panel 510. Then, the section identification number 530 is pressed after pressing the memory key. When inputting, the contents of No. 530 are played and the menu of “Edit 81 520 530” is displayed on the display panel 510. If the segment identification number 540 is entered without pressing the memory key, the contents of No. 540 are played and displayed simultaneously. On the panel 510, a menu of "Edit 81 530 540" is displayed. At this time, the section identification number 530 is displayed in a blinking state so that the user can recognize that the memory key has not been pressed.

Therefore, when the user presses the edit key in the above state, the section identification numbers 510, 520, and 540 are registered as the edit information with the edit identification number title information in the edit identification number 81, and the section identification number when the user presses the whole key. 510, 520, 530, and 540 are registered in the edit identification number 81 as the edit information together with the edit identification number title information.

That is, when the memory key signal is input as a result of the check in step 616, the process returns to step 608 described above and repeats the subsequent process, thereby inputting or editing key signal of another section identification number. Wait for input.

In addition, when the edit key signal is inputted as a result of the check in the above step 618, in the control block 204, as an example, as shown in FIG. 9A, an edit having a disc classification item and an edit identification number title item The information input menu is pulled out and displayed on the display panel 510 so as to request input of disc classification and edit identification number title information (step 622).

Next, when the user inputs the disc classification and editing identification number title information using the numeric keys and the character keys and presses the storage key (step 624), the control block 204 displays the disc classification and editing identification number title information and the section. The identification number (i.e., the section identification number on which the memory key is pressed among the section identification numbers entered by the user) is registered in the edit area of the memory block 206 together with the corresponding edit identification number in the edit area of the memory block 206 (step 626). The registration process may continue until the user presses the end key to switch the edit mode to the standby mode (steps 628 and 630).

On the other hand, if the edit key signal is inputted as a result of the check in step 620, in the control block 204, as an example, as shown in Fig. 9A, an edit having a disc classification item and an edit identification number title item The information input menu is pulled out and displayed on the display panel 510 so as to request input of disc classification and edit identification number title information (step 622).

Subsequently, when the user inputs the disc classification and editing identification number title information using the numeric keys and the character keys and presses the storage key (step 624), the control block 204 identifies the disc classification and editing identification number title information and the section identification. A number (i.e., all segment identification numbers entered by the user) is registered in the edit area of the memory block 206 as edit information together with the corresponding edit identification number (step 626). Press to continue until the edit mode is switched to standby mode (steps 628 and 630).

That is, according to this embodiment, the user selects one or a plurality of section identification numbers in one edit identification space together with the edit identification number title information while listening to the audio output of the desired section through the series of processes described above. You can register (Save) with.

In addition, when a plurality of consecutive section identification numbers are to be input when the section identification number is input, for example, when a section identification number from 601 to 630 is to be input, 601 is input and the operation panel 508 is inputted. By pressing the setup key on the top of the screen and entering 630, a plurality of section identification numbers can be easily input.

Meanwhile, although the description in the above embodiment has been omitted, in the present embodiment, the section identification number selected by the user using the delete key may be deleted.

In this way, it is possible to selectively delete the section identification number that you do not want to edit among the section identification numbers entered by the user.

At this time, the movement for selecting the section identification number to be deleted can be realized by moving the left and right directions by pressing the advance key.

For example, after inputting section identification numbers 601 to 650 and pressing the entire memory key, section editing information of 601 to 650 is registered in the corresponding edit identification number, and 631, 629, and 622 in order using the progress key. By selecting and pressing each of the delete keys and then pressing the entire memory key, the remaining section identification numbers except the selected section identification numbers can be stored in the corresponding edit identification number as section edit information.

Furthermore, when entering the editing information (disc identification information and the identification number title information) using the editing information input menu, once the disc identification information is entered, the disc identification information entered until the disc is ejected from the portable CD player. Because it is automatically set to, it is not necessary to enter disc classification information from the second registration information after registering the first edit information.

Therefore, according to the present embodiment, after switching the playback mode to the edit mode by using the storage key on the operation panel, the user can select the desired section (i.e., section identification number) to play and determine whether to edit. For example, one or more sections of the section to be selected and reproduced for editing may be selectively edited and stored in one edit space (ie, one edit identification number space).

In addition, the user may re-edit the edit contents previously edited and stored using the edit key, the delete key, and the character key in the same or similar manner to the above-described method. In other words, after selecting the desired section identification number using the progress key, the corresponding section identification number can be deleted from the edit information by pressing the delete key, and the section identification number to be added immediately before the section identification number desired to be added is entered. By pressing the memory key, any desired section identification number can be added to the edit information.

Next, a process of pre-editing the recorded contents of the optical disc using the portable CD player according to the present invention will be described.

FIG. 7 is a flowchart illustrating a process of editing contents of an optical disc in a pre-editing manner using a portable CD player according to another exemplary embodiment of the present invention.

Referring to FIG. 7, while the portable CD player is in the standby mode (step 702), the control block 204 of FIG. 2 checks whether an edit key signal is input according to a user's operation (step 704). If the edit key signal is inputted as a result of the check, the control block 204 switches the current mode to the edit mode and waits for input of the section identification number or section identification number area to be edited (step 706).
