The present invention relates to a DVD recording / playback system, and more particularly, to a method for searching MP3 files by category in a DVD recording / playback system.

In general, a DVD (digital versatile disk) recording / reproducing system refers to a device for reproducing and displaying data recorded on an optical disc such as a DVD or HD-DVD, in which data of higher density is recorded than a CD. DVD titles produced to be reproduced in the DVD can be recorded at a higher density than CDs, and have various functions as compared to conventional video media by various additional data as well as image quality.

On the other hand, in such a DVD recording / playback system, MP3 (MPEG Audio Layer-3) files can be recorded and stored, and in a digital versatile disk (DVD) system, MP3 files recorded on the DVD are read out and played back, thereby providing high quality audio data. In this case, the file names of the MP3 files are outputted and displayed through a file list screen window in the form of a list so that the user can easily select and specify the desired MP3 file. If one file name is selected and selected, a series of MP3 file play operations for reading and playing the MP3 file of the corresponding file name are performed.

However, in the conventional DVD recording / playback system, when a DVD disc with MP3 files is inserted, the playlist is displayed in the order of folders and files stored by the user, and only the up / down and prev keys are used. It only provides a user interface (UI) for moving to a track to be played by using a next key, next key, and numeric keys.

Accordingly, in the case where the number of MP3 files stored on the DVD disc is large, it is inconvenient to search for a large number of MP3 files by using the above simple navigation key in order to find the desired MP3 file.

Accordingly, an object of the present invention is to search for all MP3 files recorded by the user by category such as song name or artist name in the MP3 file search when playing a DVD disc recorded with MP3 (MPEG Audio Layer-3) in the DVD recording / playback system. By inputting the category name to the keyword as a keyword and using the ID3 tag information included in the MP3 file to display the list of the MP3 file list by category entered by the user, the user can view the MP3 file among the many MP3 files contained in the DVD large capacity disk. The present invention provides a method of searching MP3 files by category in a DVD recording / playback system that can be easily searched.

According to an aspect of the present invention, there is provided a method of retrieving an MP3 file in a DVD recording / playback system, comprising the steps of: (a) displaying an initial list of DVD stored MP3 files when loading a DVD disc on which an MP3 file is recorded; Receiving an MP3 file search request for each category from a user on the initial list list screen; and (c) receiving a category name to be searched if an MP3 file search request for each category is received; and (d) Searching for MP3 ID3 tag information and displaying a list of MP3 files corresponding to the input category name.

Hereinafter, with reference to the accompanying drawings will be described in detail the operation of the preferred embodiment according to the present invention.

1 is a schematic block diagram of a DVD recording / playback system to which an embodiment of the present invention is applied. Hereinafter, an operation of each part of the DVD system will be described with reference to FIG. 1.

In the first recording operation, the DSP (digital signal processor) 106 adds additional data for error correction code (ECC) to the encoded data and modulates the data according to a predetermined modulation scheme. A signal for driving a lens actuator (lens actuator) is generated in the pickup unit 102 according to an actuator-up / down command.

The RF amplifier 104 amplifies the electrical data input from the DSP unit 106 and converts it into an optical signal. The pickup section 102 incorporates an actuator for focusing and tracking, and records the optical signal converted by the RF amplifier section 104 on a disc.

The servo unit (servo) 108 receives the information necessary for servo control from the DSP unit 106 through the RF amplifier unit 104 and the control unit 110 to perform a stable servo. The DVD system controller 110 controls the overall operation of the entire system and transmits data to the disc through the DSP unit 106, the RF amplifier 104, and the pick-up 102 according to a user's key input. Record it.

Next, during reproduction, the pick-up 102 reads out the optical signal from the disk storing the data. The RF amplifier 104 converts the optical signal output from the pickup unit 102 into an electrical signal and extracts a servo signal and modulated data for performing servo.

The DSP unit 106 demodulates the data modulated by the RF amplifier 104, removes additional data while correcting an error by performing ECC, and the pickup unit 102 according to the actuator up / down command of the controller 110. Generates a signal for driving a lens actuator.

The servo unit 108 receives information necessary for servo control from the RF amplifier 104 and the controller 110 to perform stable servo.

On the other hand, the DVD system controller 110 searches for the MP3 ID3 tag information when the list list request for the MP3 files stored in the DVD disk is requested when the DVD disk on which the MP3 file is recorded is played according to an embodiment of the present invention. By displaying the list of MP3 file list according to the category name requested by the search, the user can easily find the desired MP3 file by searching by category such as song name, artist name, and the like.

FIG. 2 illustrates an operation control flow for quickly searching a list of MP3 files by category in a DVD recording / playback system according to an exemplary embodiment of the present invention. Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.

First, when a DVD disc on which an MP3 (MPEG Audio Layer-3) file is recorded is loaded by the user with the DVD loader, the DVD system controller 110 loads the DVD disc on which the MP3 file is recorded in step S200. . Subsequently, in step S202, the system controller displays an initial list list of the MP3 files stored in the DVD when the DVD disc loaded with the MP3 file is loaded.

At this time, the initial mp3 list is a list sequentially listing all MP3 files recorded on the DVD disc, and the user can select up / down and previous / next keys on the MP3 list. It is also possible to select a MP3 file to be played simply by sequentially searching for the MP3 file by using, and so on. According to the present invention, a MP3 configured by a specialized category such as a song name or a singer name may be requested by searching for a category and inputting a desired category name. You can also search the list of files.

If the user selects the sequential MP3 file search using the up / down key, the previous / next key, etc., the system controller 110 proceeds to the step S206 in response to the process in step S204 and lists the initial full MP3 file list. Waits for input of selection of specific MP3 file by user.

Then, when a specific MP3 file is selected from the initial full MP3 file list list by the user, the system control unit 110 proceeds to step S210 in response to the step (S208) and the initial MP3 file list by the user. Plays the MP3 file selected in the list.

On the contrary, if the user requests to search for MP3 files by category on the initial MP3 file list list screen, the system controller 110 proceeds to step S212 in response to the above step (S212) to search for MP3 files by category. Displays the MP3 search screen.

Accordingly, the user inputs a category name such as a singer name, a song name, etc. in the MP3 search screen for each category to perform a MP3 file search for a desired category. Then, the system controller 110 searches for an MP3 file from the user in step S214. By receiving the category name and searching the MP3 ID3 tag information in step S216, and displaying a list of MP3 files corresponding to the category name input by the user, a number of MP3 files recorded on the DVD disc by the user. Make it easier to find the MP3 file you want.

As described above, in the present invention, when searching for an MP3 file when playing a DVD disc recorded with MP3 in the DVD recording / playback system, a category name for searching the entire recorded MP3 files by category such as song name or artist name is used as a keyword. By displaying the list of MP3 files for each category entered by the user using ID3 tag information included in the MP3 file, the user can easily search for the desired MP3 files among the numerous MP3 files contained in the DVD mass disk.

Meanwhile, in the above description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the invention should be determined by the claims rather than by the described embodiments.

As described above, in the present invention, in the MP3 file search when playing a DVD disc recorded with MP3 in the DVD recording / playback system, a category name for searching the entire recorded MP3 files by category such as song name or singer name is searched for. By displaying the list of MP3 files by category entered by the user using ID3 tag information included in the MP3 file, it is easier to search the MP3 files that users want among the numerous MP3 files contained in the DVD large capacity disk. This has the advantage.
