In order to achieve the above object, the present invention provides a method of reading a directory from a storage medium in which a multimedia file is stored, retrieving a directory including a predetermined file from the read directory information, and retrieving the retrieved directory. And displaying a user interface for directory information of the storage medium serving as a top-level directory.

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

1 is a schematic block diagram of a user interface display device for directory information according to an embodiment of the present invention, including a driving unit 100, a decoder 200, an input unit 300, a search unit 400, a user interface unit 500, It is configured to include a display unit 600 and the control unit 700.

The driver 100 picks up and outputs data information from a storage medium in which a multimedia file is stored. For example, the driver 100 picks up data information recorded on the compact disc A through focusing and tracking.

The decoder 200 receives the data picked up by the driving unit 100 and decodes the data to be output as an audio signal or a video signal.

The input unit 300 outputs a predetermined control signal according to a button selected by the user, and transmits a predetermined control signal to the controller 700 when a button input is input from the user.

The search unit 400 searches a directory including a predetermined file in directory information of a storage medium in which the multimedia file is stored, and the search unit 400 inputs a top-level directory where the predetermined files exist and a user inputs the directory. Search for files matching the criteria. In addition, the directory searched from the search unit 400 is a top-level directory in which the predetermined files exist.

The user interface manager 500 generates a user interface for directory information of the storage medium, and the searched directory is highlighted in a predetermined manner, using the searched directory as a top directory, and generating a user interface for directory information of the storage medium. do.

The display unit 600 displays the user interface, that is, displays a user interface whose uppermost directory is the searched directory and a user interface in which the searched directory is highlighted in a predetermined manner.

The controller 700 controls the operation of the storage medium according to the control signal output from the input unit 300.

2 is a flowchart schematically illustrating a user interface display method for directory information according to the present invention. First, when a compact disc A is inserted, the driving unit 100 controls data information of the inserted compact disc A. FIG. Forward to 700.

Next, when the controller 700 reads out directory information from the received data information and transmits the directory information to the search unit 400, the search unit 400 searches a directory including a predetermined file in the transmitted directory information. (S10, S20). That is, a directory is checked by selecting a root directory from the searched directory structure to determine whether a predetermined file or a child directory exists and includes a predetermined file based on the check result. Search for a directory. Here, the predetermined file refers to a file corresponding to a condition input by the user, for example, MP3, JPEG, WMA, or the like. The process of checking the status of the directory and searching a directory including a predetermined file will be described again with reference to FIGS. 4 and 5.

Next, when the user interface 500 generates a user interface for directory information of a storage medium having the searched directory as the best directory, and transmits the generated user interface to the display 600, the display unit ( 600 displays the received user interface (S30). That is, the searcher 400 generates a user interface for a directory including a predetermined file based on the result of checking the directory status, and displays the best directory or highlight. The process of displaying the user interface will be described again with reference to FIG. 6.

FIG. 3 is a diagram illustrating a directory structure for explaining a user interface display method of directory information according to the present invention, in which a plurality of subdirectories and a plurality of files are included in a root directory. 4 to 6 will be described below with reference to the directory structure.

4 is a flowchart schematically illustrating a method of checking a state of a directory in a user interface display method of directory information according to the present invention. First, the search unit 400 is a root directory in a directory structure read by the control unit 700. (S100), it is determined whether a file and a directory including the file exist in the root directory (S101 and S103).

As a result of the determination, when the file and the directory including the file exist, the state of the directory is displayed as TRUE, and when the file or the directory including the file does not exist in the directory, the state of the directory is displayed as FALSE (S102, S104). To S106). Herein, it is determined whether a directory including a file and a file exists in all directories existing below the root directory, and the display method is shown in the order of directory existence / file existence.

Next, the states of the subdirectory and the sibling directory perform the same process to display the states (S107 to S122). Here, the status display of the directory is performed for all directories, and a search of a directory including predetermined files to be described in FIG. 5 is performed based on the status display of each directory.

Hereinafter, the state display process of the directory will be described in more detail. First, the root directory is selected (S100), and then the state of the root directory is checked. That is, it is determined whether an MP3 file or a directory including the MP3 file exists in the root directory (S101).

First, it is determined whether an MP3 file exists in the root directory. Referring to FIG. 3, the MP3 file does not exist in the root directory, and as a result of determining whether a directory having the MP3 file exists, a subdirectory exists in the root directory. However, since it is not known whether or not the MP3 file is included in the subdirectory, the state of the root directory is displayed as FALSE / FALSE (S101, S103, S105, S106).

Then, it is determined whether a directory exists below the root directory (S110). As a result of the determination, since a subdirectory exists, the selection point is moved to the corresponding subdirectory (that is, subdirectory 1), and then the state of the selected directory 1 Check (S112). Here, as a result of determining whether the MP3 file in the directory 1 exists and whether the directory having the MP3 file exists, the MP3 file does not exist in the directory 1, and although the subdirectory exists, the MP3 file is included in the subdirectory. Since the state of the directory 1 is unknown, FALSE / FALSE is indicated.

Next, it is determined whether a directory exists under the directory 1 (S110). As a result of the determination, since the sub directory exists, the selection point is moved to the corresponding sub directory (ie, the directory 3), and the state of the selected directory 3 is checked. (S112). Here, as a result of determining whether a file exists in the directory 3 and whether a directory having a file exists, the directory 3 has an MP3 file, and since a subdirectory exists, it is not known whether the MP3 file is included in the subdirectory. The state of the directory 3 is indicated as FALSE / TRUE.

Next, it is determined whether a directory exists above directory 3 (S107), and as a result of the determination, since a directory exists above directory 3, the directory 1 and the root directory files existing above directory 3 are included. Change the display of directories to TRUE. Thus, the state of directory 1 and the root directory is changed to TRUE / FALSE.

Next, it is determined whether a directory exists under the directory 3 (S110). As a result of the determination, since the sub directory exists, the selection point is moved to the corresponding sub directory (ie, the directory 5), and then the state of the selected directory 5 is changed. Check (S112). Here, the directory 5 has MP3 files, and since the subdirectory does not exist, the state of the directory 5 is represented as FALSE / TRUE.

Next, it is determined whether a directory exists under the directory 5 (S110). As a result of the determination, since the subdirectory does not exist, it is determined whether the sibling directory of the directory 5 exists (S116).

As a result of the determination, since the sibling directory of the directory 5 does not exist, it is determined whether the directory 5 is the root directory (S120). As a result of the determination, since directory 5 is not the root directory, the selection point is moved to an upper directory of the directory 5 (that is, directory 3) (S122).

Next, it is determined whether a sibling directory of the directory 3 exists (S116). Since the sibling directory 4 exists as a result of the determination, the state of the selected directory is checked (S118). Here, the directory 4 is represented as FALSE / FALSE because there are no subdirectories and MP3 files.

Next, it is determined whether a subdirectory of the directory 4 exists (S110). Since the subdirectory does not exist, the directory 4 determines whether a sibling directory exists (S116).

Since the sibling directory of the directory 4 does not exist as a result of the determination, it is determined whether the directory 4 is the root directory (S120), and as a result of the determination, the directory is not the root directory, so that the upper directory of the directory 4 (ie, the directory 1). In step S122, the selection point is moved.

Next, it is determined whether a sibling directory of the directory 1 exists (S116), and as a result of the determination, the sibling directory 2 exists, and the state of the selected directory is checked (S118). Here, the directory 2 state is represented as FALSE / FALSE because there is no subdirectory and no MP3 file.

Next, it is determined whether a subdirectory of the directory 2 exists (S110). Since the subdirectory does not exist, the directory 2 determines whether a sibling directory exists (S116).

Since the sibling directory of the directory 2 does not exist as a result of the determination, it is determined whether the directory 2 is the root directory (S120), and as a result of the determination, the directory is not the root directory, so that an upper directory of the directory 2 (that is, the root directory) is determined. In step S122, the selection point is moved.

Then, it is determined whether a sibling directory of the root directory exists (S116), and since the sibling directory does not exist as a result of the determination, it is determined whether the selected directory is the root directory (S120). As a result of the determination, since the selected directory is the root directory, the state check for each directory is finished.

Therefore, when looking at the status check result of each directory, the root directory is displayed as TRUEF / FALSE, directory 1 is displayed as TRUEF / FALSE, directory 2 is displayed as FALSE / FALSE, and directory 3 is displayed as TRUE / TRUE. Directory 4 is labeled FALSE / FALSE, and Directory 5 is labeled FALSE / TRUE.

FIG. 5 is a flowchart schematically illustrating a method of searching for a location of a directory including a predetermined file based on the state of a directory checked in FIG. 4 in the user interface display method of directory information according to the present invention. The search unit 400 selects a root directory from the directory structure read by the controller 700 (S200), and determines whether a file exists in the selected root directory (S202). In this case, the existence of the file may be determined based on a result of a state check of each directory in FIG. 4.

If there is a file as a result of the determination, the selected root directory is set as a directory where a predetermined file exists (S208).

If it is determined that the file does not exist, it is determined whether two or more directories including the file exist (S204 and S206). If there are two or more directories containing the result of the determination, the selected root directory is set to a directory in which the predetermined file exists (S208). If there is one directory containing the determination result, the selection point is a subdirectory. In step S210 and S212, the file is determined whether the file exists in the subdirectory.

On the other hand, if it is determined that one or more directories having files or no directories having files exist, it is determined that an error or a corresponding file does not exist (S214, S216).

Hereinafter, a process of searching for a location of a directory including a predetermined file will be described in detail. First, a root directory is selected from the searched directory structure (S200), and an MP3 file is present based on state information of the selected root directory. It is determined whether or not (S202).

As a result of the determination, since the MP3 file does not exist, after determining whether the directory having the MP3 file exists in the root directory (S204), it is determined whether there are two or more directories having the MP3 file among the lower directories of the root directory. (S206).

As a result of the above determination, since directory 1 is a directory containing MP3 files, but directory 2 is not a directory containing MP3 files, that is, two or more directories containing MP3 files do not exist, the selection point is a subdirectory (that is, directory 1). Move to).

Next, the existence of the file is determined based on the state information of the directory 1 (S202). As a result of the determination, the directory 3 is a directory having the MP3 file, but the directory 4 is not a directory having the MP3 file. Since there are no more than one directory containing MP3 files, move the selection point to a subdirectory (ie directory 3).

Next, it is determined whether the MP3 file exists based on the state information of the directory 3 (S202). As a result of the determination, since the MP3 file exists in the directory 3, the directory 3 is set as a directory in which the predetermined file exists (S208).

FIG. 6 is a flowchart schematically illustrating a method of displaying a location of a directory having a predetermined file searched for in FIG. 5 among a user interface displaying method for directory information according to the present invention. A directory having a file of is set as a root directory (S300), and it is determined whether a file or a directory having a file exists in the set directory (S302).

As a result of the determination, if a directory having a file or a file exists in the set directory, the user interface unit 500 generates a user interface for directory information of the storage medium having the file or the directory having the file as a top level directory. The display unit 600 is transmitted to the display unit 600, and the display unit 600 displays the received user interface (S304).

If the file or the directory having the file does not exist in the set directory, it is determined whether the sibling directory exists. If the sibling directory exists as a result of the determination, the selection pointer is moved to the sibling directory, and it is determined whether a file or a directory having a file exists in the selected sibling directory (S308).

On the other hand, if the sibling directory does not exist as a result of the determination, it is determined that the directory having the file desired by the user does not exist and the display of the directory is not performed.

Hereinafter, a process of displaying a location of a directory having a predetermined file will be described in detail. First, a directory having a predetermined file searched in FIG. 5, that is, a directory 3 is set as a root directory (S300), and the set directory is provided. In step 3, it is determined whether a file or a directory having the file exists (S302).

As a result of the determination, in the case of FIG. 3, since the MP3 file exists in the directory 3, a user interface having the directory 3 as the top directory is generated, and the directory 3 is displayed as the top according to the generated user interface (S304). Shown in Figure 7 (a)).

Meanwhile, a user interface may be created to highlight the directory 3 including the MP3 file in a predetermined method, and the directory 3 may be highlighted and displayed according to the generated user interface (shown in FIG. 7B). ).

This makes it easy for the user to find the location of the directory containing the file he wants to search.

Although the present invention has been described in detail above, those skilled in the art to which the present invention pertains may variously modify the present invention without departing from the spirit and scope of the present invention as defined in the appended claims. It is apparent that the present invention may be modified or modified. Therefore, a simple change according to an embodiment of the present invention will not be possible without departing from the technology of the present invention.

According to the present invention of the above configuration, by extracting the location of the directory containing the file that the user wants to search from the directory information of the storage medium in which the multimedia file is stored by displaying a user interface that makes the extracted directory as the top directory The user has the advantage of facilitating a search for a desired file.
