In addition, the memory 170 stores information on a recently played recently list for recent playback. The memory 170 may largely include a program area and a data area.

The program area may include an operating system (OS) for booting the mobile terminal 100, an application required for multimedia playback, other options of the mobile terminal 100, for example, a sound playback function, an image or video playback function. Store applications, etc. required.

In particular, the program area stores an MP3 application for an audio reproduction function of the sound reproduction function. The program area stores an application for displaying the audio sound source file list. The file list display application will be described in more detail together with the description of the display unit 150.

The data area is an area in which data generated according to the use of the mobile terminal 100 is stored, and various files such as video files, text files, and audio source files are stored. In particular, music-related audio source files are stored. It is an area. In more detail, a plurality of audio sound source files stored in the data area are stored in a database according to categories such as albums, genres, artists, and names. That is, the audio source file stores a plurality of audio tracks, and stores classification information classified by album, genre, artist, and name so that the user can easily select the plurality of audio tracks. The classified information is displayed in the first area of the display unit 150, for example, the index area.

The key input unit 130 includes a plurality of input keys and function keys for receiving numeric or character information and setting various functions. The function keys may include direction keys, side keys, shortcut keys, and the like, which are set to perform a specific function. In addition, the key input unit 130 transmits a key signal input in relation to user setting and function control of the portable terminal 100 to the controller 160.

In particular, the key input unit 130 is a key signal for selecting an application for audio source playback, an audio source file selection signal loaded according to the activation of the audio source playback application, the audio source file being reproduced according to an embodiment of the present invention. A key signal for controlling playback, that is, playback, fast-forwarding, rewinding, pausing, and stopping, is generated and transmitted to the controller 160.

The audio processor 140 reproduces an audio signal such as a voice required for a call or delivers an audio signal such as a voice input from a microphone to the controller 160. In particular, the audio processor 140 of the present invention reproduces the track when a user's selection of various audio source files, in particular, a track, displayed on the display unit 150 occurs.

The display unit 150 displays various menus of the mobile terminal 100, information input by the user, or information provided to the user. In particular, the display unit 150 provides a screen interface for selecting an audio sound source file according to an embodiment of the present invention. The screen interface will be described in more detail with reference to FIG. 2.

2 is an exemplary view illustrating a screen of a display unit for selecting a file of a mobile terminal according to an exemplary embodiment of the present invention.

The audio sound source file may have names of various sound source files such as an album, a singer, and a genre. For convenience of description, the audio sound source file will be referred to as a track in the following description. That is, hereinafter, "audio source file" and "track" are used interchangeably.

Referring to FIG. 2, the display unit 150 according to the present invention includes a first area and a second area, for example, an index area and a list area, to indicate one of each index of the index area. It may include a cursor that moves according to the key input of the key input unit 130.

The index area may have a value corresponding to the first letter of the file name of the audio source file as an index. For example, when the file name of the audio source file is "Aria", it may be assigned to the category of "A" in the index area, and the "Aria" track when selecting and specifying "A" in the index area as a cursor. The list area where you can see is activated. In the file activation control method according to an embodiment of the present invention, the article of the track corresponding to each index of the index area may not be applied. That is, since the name of a track can be assigned with a high frequency of definite articles or indefinite articles, a track with an index of "A" or "T" can be assigned. In this case, since it may cause more confusion in finding specific information, except for articles, it is desirable to classify the first letter of the first word following in each category of the index area.

A cursor is positioned in the index area, and the cursor may move left and right in response to a key input of the key input unit 130. In this case, the key input unit 130 may be composed of left and right direction keys or wheel keys for moving the cursor. When the cursor is located at a specific index in the index area, track information included in the index is displayed in the list area.

The list area is an area where tracks corresponding to the selected index are displayed when any one of the indexes arranged in the index area is selected. As shown in FIG. 2, when the index “A” is selected, an audio sound source file corresponding to “A”, that is, a song title may be displayed. In order to select a specific song among the songs in the list area, when the user generates a confirmation key input signal using the key input unit 130 with respect to the cursor located at the specific index in the index area, the cursor moves to the list area. Accordingly, the cursor located in the list area may move up and down in response to the input of the key input unit 130 to select a track desired by the user. Here, the activation of a specific track transmits the key input signal to the controller 160 when a key input signal corresponding to a confirmation key input is generated for a track on which the moving cursor is stopped.

In addition, when displaying the tracks of the index designated by the cursor arranged in the index area, the list area may display the song having the highest alphabetical priority when the list of tracks is larger than the list area. Tracks not displayed in the list area may be displayed in response to the movement of the cursor.

The list area may display an entire track list corresponding to the entire index area as the cursor moves. That is, the display unit 150 displays only a track list corresponding to a specific index of the index area, or preferentially displays a track list corresponding to the designated specific index, and subsequent tracks are arranged in alphabetical order. Can be. The entire track list may be displayed on the display unit 150 as the cursor moves. On the other hand, if only a track list corresponding to the specific index is displayed on the display unit 150, and there are more track lists to be displayed in total than the size of the display unit 150, the list area displays a predetermined track list on the display unit 150. After that, the remaining track list may be displayed on the display unit 150 in response to the movement key input signal.

Meanwhile, the list area displays only the track list corresponding to the index on the display unit 150, and the track list corresponding to another index is displayed on the display unit 150 only when the corresponding index is designated. In this case, the index group may be grouped and displayed. For example, track lists corresponding to specific indexes "S", "T", and "U" may be displayed by sorting the track lists corresponding to respective indexes on the display unit 150.

The display unit 150 of the present invention having such a configuration can move to an interface for selecting the audio sound source file through a menu interface, and a function for displaying an interface for selecting the audio sound source file is assigned to a specific hotkey. When the hotkey is activated, the selection interface can be displayed.

Meanwhile, the display unit 150 may include a separate additional index as shown in FIG. 3.

The additional index illustrated in FIG. 3 is an index for selecting a recent play list of the portable terminal 100 and may be displayed as an index designated at the time of designing and manufacturing the portable terminal 100, for example, special characters. . If the display unit designates an index corresponding to the recent play list with the cursor, the display unit displays a recently played list in a list area.

The recent play list may include not only track information corresponding to one song of a specific sound source, but also an upper category having the lower category, that is, album information and artist information. That is, when a sound source corresponding to the entire album is played among the recent playlists of the portable terminal 100, album information corresponding to the album is included in the list. In the same manner, when all sound sources corresponding to a specific singer among the sound sources stored in the memory 170 of the portable terminal 100 are reproduced, the singer information corresponding to the singer is included in the list. When the album information and the artist information list included in this way are reproduced, all the sound sources included in the album information are reproduced again, and all the sound sources corresponding to the singer information may be reproduced again.

Such an additional index indicating the latest playlist is limited to a certain number, for example, the number of seven lists, and when a new recent playlist is generated, the newest playlist is deleted from the oldest list and the new playlist may be registered. The recent playlist thus formed may be stored semi-permanently. The recent playlist initialization may be initialized and deleted when the portable terminal 100 is reset or when the terminal is turned on or off. The latest playlist may be automatically deleted after a predetermined time, for example, about one day has elapsed. It may be set to initialize.

The controller 160 controls the overall operation of the portable terminal 100 and a signal flow between internal blocks of the portable terminal 100. The controller 160 may include functions of a modem and a codec.

In particular, the controller 160 controls the display unit 150 to display an interface screen for selecting an audio sound source file in response to an input signal of the key input unit 130, and among the index areas in response to the input key input signal. The display unit 150 is controlled to display a track list corresponding to the designated index. In addition, when any one track of the track list is selected by the key input unit 130, the controller 160 loads and activates an application for activating the track from the memory 170.

On the other hand, the controller 160 controls to generate the latest play list. In more detail, the controller 160 controls to allocate the recently played list to a separate additional index by including a track list selected and reproduced in the audio source file selection interface in a recent play list. Here, the recent play list may include not only a list corresponding to a single song, but also album information or singer information including a plurality of track lists as a list. That is, when all track lists included in the album are played under the album name, the controller 160 includes the album name in the recent playlist, and even when all track lists included in the singer are played under the artist name. The singer name is included in the recent playlist. Subsequently, when the album name and the singer name registered in the recent play list are indicated and activated, the controller 160 controls to play all the track lists included in the album name and the singer name, respectively.

The mobile terminal 100 according to the embodiment of the present invention may further include a radio frequency unit 110 when the mobile communication terminal. The radio frequency unit 110 wirelessly transmits user data to another external mobile terminal or the like, or a series of communication related to transmission and reception of an audio sound source file through interworking with an external web server and a WAP server. In charge of. The radio frequency unit 110 may include a radio frequency transmitter for upconverting and amplifying a frequency of a transmitted signal, and a radio frequency receiver for low noise amplifying and downconverting a received signal.

In particular, the radio frequency unit 110 may receive the audio source file from a mobile communication system or an external WAP server and store the audio sound source file in the memory 170 through the controller 160.

Meanwhile, FIG. 2 illustrates a block configuration for explaining an operation according to an embodiment of the present invention for convenience of description, but the present invention is not limited to this configuration. Therefore, the mobile terminal 100 of the present invention may further include a multimedia module and / or a digital broadcasting module according to the provision form thereof.

In the above, the configuration of the apparatus for controlling file activation of a mobile terminal according to an embodiment of the present invention has been described. Hereinafter, a method of controlling file activation of a mobile terminal according to an embodiment of the present invention will be described.

4 is a flowchart illustrating a file display method of a mobile terminal according to an exemplary embodiment of the present invention.

Referring to FIG. 4, in the file display method of the mobile terminal of the present invention, first, the controller 160 detects generation of a key input signal corresponding to screen interface selection for selecting an audio sound source file (S101). The key input signal corresponding to the screen interface selection may be a key input signal corresponding to a hot key, or may be a key input signal for selecting a category of a menu. In the step S101, when there is no key input signal generation for switching the screen interface for audio source file selection, the portable terminal 100 has a corresponding function, for example, a mobile communication function and a video provided by the portable terminal 100. The playback function, the broadcast listening function, etc. may be performed (S102).

In step S101, when the key input signal is generated, the controller 160 inspects an audio sound source file stored in the memory 170 (S103). In addition, the controller 160 checks whether there is a list of the audio sound source files classified by each index (S104). If there is no list, the controller 160 generates a list by classifying the files by file names of the audio sound source files (S105). ).

If there is a list in step S104, step S105 may be omitted.

In the step S105, the control unit 160, while generating a classification list, each first letter of the audio source file as a category index, in the case of the alphabet, ignores the article and recognizes the next first letter as an index. That is, the controller 160 checks whether or not the first word of the file name of the audio sound source file is an article or, if not, recognizes the first letter as the index and performs classification by index. However, if the first word is an article, the controller 160 disregards the first word and recognizes the first letter of the next word as an index and performs classification by index.

On the other hand, if there is a classification list in step S104 or a classification list is generated in step S105, the controller 160 displays the index of the classification list on a predetermined area of the display unit 150 (S106). That is, the controller 160 displays the indices of the audio sound source file in the index area.

In addition, the controller 160 detects an index in which a cursor for specifying a specific index among the indices displayed in the index area is located (S107), and displays a list of audio source files included in the index where the cursor is located (S108). ). In the index designation, the cursor is an indicator indicating one of a plurality of indices displayed in the index area, and the index designation has a form and color in which the shape or color of the designated index can be distinguished from the surrounding index without a separate cursor. This can be done. That is, the controller 160 may perform index designation by changing the shape and color of the designated index such as inverting the color of the designated index, repeating blinking, or controlling to display larger than the surroundings.

Next, the controller 160 checks whether a key input signal for moving the cursor is generated (S109). If there is no key input signal, the process branches to step S108 to display a list area corresponding to the index where the current cursor is located.

Next, when the movement key input signal occurs in step S109, the controller 160 moves the cursor by moving the cursor by the number corresponding to the key input signal from the index currently designated in the index area. Control to specify the index corresponding to the position (S110). If a new index is specified in step S110, the controller 160 updates the list area to display a list of audio source files corresponding to the specified index in the list area in step S108 (S111).

As described above, in the file display method according to an embodiment of the present invention, the audio source files stored in the memory 170 are classified by index to display an index in the index area, and list information corresponding to each index is displayed in the list area. After that, the list corresponding to the designated index is displayed in the list area, thereby quickly and easily displaying the audio source file to be selected.

5 is a flowchart illustrating a method of selecting and activating a file in the above-described file display state.

Prior to the description, it is assumed that the screen interface for the file activation method of the present invention displays each index in the index area and displays a list of audio sound source files corresponding to the index designated by the cursor in the list area.

Referring to FIG. 5, in the file activation method of the mobile terminal of the present invention, first, the controller 160 checks whether a key input signal is generated from the key input unit 130 (S201). When the key input signal is generated in step S201, the controller 160 determines whether the key input signal is a key input signal corresponding to the confirmation key (S202). In step S202, when the key input signal is a key input signal corresponding to a confirmation key, the controller 160 moves focusing, for example, moves the cursor to the current list area (S203). When the cursor moves to the list area, that is, focusing moves, the cursor indicates one of the audio sound source files displayed in the list area. The cursor may default to the audio source file displayed at the top of the list by default.

If the key input signal does not occur in step S201, the initial state is maintained, and if the key input signal other than the confirmation key is performed in step S202, the corresponding function is performed (S204). For example, the function moves the cursor in the index area in the case of a key input signal corresponding to a direction key, and terminates the current job in the case of a key input signal for a separate end. In addition, the corresponding function may show corresponding lists when the audio source file is an upper category, for example, when album names or singer names include lower tracks.

Next, the controller 160 checks whether the key input signal corresponding to the playback key has been generated again while the cursor indicates one of the audio sound source files displayed in the list area (S205). If the playback key is input in step S205, the controller 160 activates an audio playback application for playing the currently indicated audio sound source file (S206), and plays the audio sound source file (S207).

On the other hand, in step S205, the control unit 160 checks whether a key input signal corresponding to a direction key instead of a playback key is generated (S208). In the case of the direction key signal in step S208, the control unit 160 designates one of at least one audio sound source file displayed in the list area by moving the cursor in response to the direction key (S209).

In the step S208, if it is not the direction key, it branches to the step S204 can perform a function corresponding to the input key input signal.

As described above, in the file activation method of the present invention, when a specific index displayed in the index area is designated by the cursor, a list of audio sound source files included in the index is displayed in the list area. The controller 160 moves the cursor to the list area according to the confirmation key input, designates one of the audio source file lists included in the list area according to the direction key, and selects the audio source file selected by the confirmation key. Control to play.

6 is a flowchart illustrating a recent play list generation method of the present invention.

Referring to FIG. 6, in the method of generating a recent play list of the mobile terminal of the present invention, first, the controller 160 checks whether one file of an audio sound source file list is played (S301).

In step S301, when a specific audio sound source file is played, an additional index to classify the played audio sound source file name is generated (S302). In the step S301, when the file reproduction related function is not performed, the controller 160 controls the display unit 150 to display or search a corresponding function provided by the mobile terminal 100, for example, various lists. Perform a function (S303).

Next, the controller 160 extracts the file name of the audio source file being played (S304), and registers the audio source file name in the additional index category (S305). In operation S304, the controller 160 may extract the file name of the audio sound source file with reference to the file name information stored in the memory 170. In step S305, the controller 160 stores a file name of the recently reproduced audio source file by allocating a separate storage area that is distinguished from an area in which the file name of the audio source file is stored in order to register the audio source file name. Can be. Here, the information stored in the separate storage area may be initialized or deleted by user selection. In addition, the controller 160 may repeatedly perform the audio sound file name registration performed in step S305.

Thereafter, the controller 160 displays the additional index in the index area (S306).

Next, the controller 160 checks whether a cursor designates the additional index (S307), and if the cursor designates the additional index, the audio source file list registered in the additional index is displayed in the list area. (S308).

In step S307, when the cursor designates another index, a list included in the index is displayed (S309).

On the other hand, in step S305, the controller 160 checks whether the number of the audio sound source files to be registered in the additional index category is greater than or equal to a predetermined number, and if more than the set number, the file name of the currently registered audio sound source file Can be listed at the top of the index list, and the file name of the oldest audio source file can be deleted.

The audio source file of the present invention may include both the name of an album, the name of a singer, and the name of a track included in the album and the singer category. That is, the index may recognize not only the index corresponding to the track included in the album and the singer, but also the album and the singer as an index and display the index in the index area. Can be marked on.

In addition, when the album names or artist names displayed in the list area are selected by the cursor, the controller 160 may control to perform other functions according to a key input signal. That is, the controller 160 selects the tracks included in the album or the singer in a random or album-listed order when a "play" key input signal occurs after being selected by the cursor among the album name or the singer name displayed in the list area. It can be controlled to play as it is. When the "confirmation" key input signal is generated, the controller 160 may control to switch to a window displaying detailed information of the album or singer, for example, tracks included in the album or singer.

That is, the method and apparatus for controlling file activation according to an embodiment of the present invention are not limited to the types of audio sound source files, but classify various audio sound source files by index, and the classified indexes are included in each index. The list is displayed in the list area.
