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

1 is a view showing the overall configuration of a digital music reproduction apparatus using a CD as a storage medium according to an embodiment of the present invention.

Referring to Fig. 1, a CD driver 106 composed of an optical pickup / RF amplifier means 100, a digital signal processing means 102, a motor drive and control / servo means 104 is coupled to a processor 108. .

The CD driver 106 reads data from a compact disc (not shown) and transfers it to the processor 108.

The processor 108 stores the data received from the CD driver 106 in the first memory 110 or decompresses and stores the data in the first memory 110 when the data is compressed.

The processor 108 also controls the exchange of data between the various components coupled thereto.

The DA converting means 116 converts the digital data processed by the processor 108 into analog data and outputs the analog data to the speaker 118.

Interface means 114 is coupled to the processor 108 to perform data exchange with external devices.

The control means 120 is coupled to the processor 108 to process the data input from the key input means 122 and output the processed results via the display means 124. Since the functions of the control means 120 may also be performed by the processor 108, the control means 120 may be included in the processor 108.

2 is a flowchart illustrating a music file playing method in a directory repeat play mode according to an exemplary embodiment of the present invention.

Referring to FIG. 2, first, in step 200, a directory repeat play mode is set and a directory is selected. This setting and selection process may be performed by a user or by an internal program.

Next, in step 202, music files are played. This process can be implemented programmatically or in hardware. In general, in the case of a compressed music file, the decoding process is accompanied by a decoding process. The process may be performed through a decoding program or a chip dedicated to the decoding process.

Next, in step 204, it is determined whether it is a directory repeat play mode. If it is determined that directory repeat play mode is performed, step 206 is performed. If directory repeat play mode is not present, step 208 is performed.

Determination of whether the mode is a repeat playback mode is performed by using a conditional command (for example, an IF statement in C language) to determine what kind of information about the previously set mode is. The determination point is when the reproduction of the file has ended, and the detection of the termination point of the file is performed by extracting the reproduction time of the file.

In step 206, the files in the selected directory are repeatedly played, and in step 208, the next file is played in the predetermined order. The playback order may be determined internally or may be determined by a user. If there is no specially determined order, playback is performed according to the internally defined order (DEFAULT).

According to an embodiment of the method of repeatedly playing a file in a directory, first, it is determined whether the file is the last file in the directory, and if the result is the last file, the next file is played. If the file is the last file, the file is moved to the first file in the directory. Play it.

On the other hand, when it is assumed that the next file is played back in step 208, the next file is the next file which does not consider the directory structure, and thus is different from the next file (the next file in the directory) in the above directory reproducing mode.

The limitation of the file to the music file in the above embodiment is for technical convenience, and is not particularly limited to the music or voice file, but is applied to all kinds of media files. Media files include audio files (typically files with extensions such as AU (AUdio), WAV (WAVe), MP3, WMA (Window Media Audio), AAC (Advanced Audio Coding),) graphics files (typically BMP (BitMaP). ), Files with extensions such as Graphics Interchange Format (GIF), Joint Picture expert Group (JPG), Tag Image File format (TIF), video files (usually AVI (Audio Video Interactive), and Motion Picture expert Group ), Files having extensions such as QT (Quick Time), RAM, etc.), and the above method can be applied to their reproduction. This applies to all examples below. In addition, the above steps can generally be easily implemented by a program.

Meanwhile, the directory repeat play mode used in the above embodiment may be replaced with a single file repeat play mode or an interval repeat play mode.

The single file repeat play mode refers to a mode in which a function of repeatedly playing only a file currently being played is set. Such a function can be implemented by programming to play the file again at the end of file playback.

The section repeat play mode refers to a mode in which a plurality of directories are set as sections and a function of playing files contained therein in a predetermined order is set. This function allows to play the first play file of another directory that is already set when the play of one directory is finished, and detects the last directory of the section so that the last directory of the section is the first play of the section in the directory. It can be implemented by programming to play the first play file in the directory.

Referring to FIG. 3, first, in step 300, the directory repetition mode is set.

Next, the determining of the music file playback and the directory repeat playback mode is as described above. However, in the case of the directory repetition mode, step 306 is executed.

In step 306, the music file in the directory including the music file being played is repeatedly played. In other words, the user can repeatedly play the directory by inputting a directory repetition request while the music file is being played without specifying the directory from the beginning. This is a very convenient function for the user.

For example, if the user stores only the music files desired by the user, the user can automatically listen to the desired music files by recognizing a certain music file and inputting a directory repeat play request.

This step is specifically inputted by pressing a predetermined button for the directory replay request, and when this input is an interrupt request for the processor, the interrupt processing routine stores the button code and interprets the stored button code in the main routine. It can be implemented by setting the playback mode to the directory repeat playback mode.

Here, the main routine refers to a program routine that implements the process according to the above flowchart, and the interrupt processing routine refers to a routine that implements the process for setting the directory repeat regeneration mode.

Referring to FIG. 5, first, in step 500, a directory to be played repeatedly is created.

Next, in step 502, a music file to be repeated is assigned to the directory. In this case, when the generated directory is to be used again, a step of deleting files in the existing directory may be added.

In addition to these steps, steps such as playing a music file are as described above.

6 is a diagram illustrating a structure of a voice file used for reproducing a voice file in a unit repeat play mode according to an exemplary embodiment of the present invention.

Herein, the unit refers to an area up to the start point and the end point of the divided portion when the media file is divided according to a predetermined purpose. For example, a word or sentence of a voice file or a video file in which various pieces of work are stored in one file may correspond to a part corresponding to the piece of one piece. However, in the above-described embodiment and the following embodiments, for convenience, it will be described by limiting it to a unit of a voice file.

Referring to FIG. 6, a voice file has a structure in which there are a plurality of voice units and a portion separating them (usually called a separator) is therebetween. A speech file having such a structure may be generated by inserting a delimiter in advance, or may be detected by a program or hardware. Here, the information about the separator may be stored in a separate file, or temporarily stored in a memory or the like by a program.

For example, in the case of a voice file in which a plurality of sentences are recorded, there is a pause period in which a speech is not output between sentences in general or for a specific purpose, and may be detected by a program or hardware to distinguish sentences from sentences.

On the other hand, the term "audio file" herein refers to a file whose main content is human upbringing. This is the same in all the examples below.
