For example, the memory may be a flash memory such as an SD card. The database may be formed of a file such as "external.db ", for example. These database files can be deleted and newly created or updated using existing database files.

The control unit 180 may update the data files and directories stored in the memory 160. [ Updating a data file in the database may mean, for example, inserting link information of the data file into the database. As another example, it may mean that the link information of the data file is updated in the database.

 The method of generating the database file can be implemented in various ways. For example, a database file may be created after the update of all the data files stored in the memory 160 is completed, or an update of the data files may be performed after the database file is created. Hereinafter, a method for the controller 180 to create and update a database will be described in detail with reference to FIGS. 3 and 4. FIG.

3 and 4 are flowcharts illustrating a control method of a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 3, a method of controlling mobile terminal 100 according to the present invention includes dividing data files into first and second groups (SlOO). The control unit 180 may classify all data files stored in the memory 160 into a first or a second group. The data files may be a collection of data stored in the memory 160. [ At this time, the memory 160 may be a flash memory, which is an auxiliary storage device, and the stored information is not erased even when the power is turned off.

The first group may consist of files that are given priority to update data files that are updated in the database according to a media transfer protocol (MTP). And the second group may consist of files different from the first group.

The priority of the update may vary depending on whether or not it is a data file required to execute the application. For example, the control unit 180 may classify the data file into a first group if it corresponds to at least one of video, audio, and image files, and a second group if not.

Next, a step of updating the first group to the database may proceed. The control unit 180 may update the files included in the first group among the data files stored in the memory 160 to the database in advance.

When the first group consisting of the files with the update priority is updated in the database, the control unit 180 can execute the application using the at least one data file included in the first group have.

Next, after completing an update to the first group so that the application is executed before the update to the second group is completed, the step of updating the second group to the database may proceed . The controller 180 can perform multitasking to perform several tasks at the same time. Accordingly, the control unit 180 can execute an application that uses at least one data file included in the first group, while updating the second group. Accordingly, the control unit 180 may sequentially update the first and second groups to the database.

Thus, according to the present invention, the mobile terminal 100 divides the data files stored in the memory 160 into first and second groups, and allows the application to be executed before the updating of the second group is completed, Since the first and second groups can be sequentially updated in the database, the application can be executed using the data files while updating the database. Thus, the time required to execute the application can be shortened.

4 is a flowchart for explaining a step S100 of dividing data files into a first group and a second group.

Referring to FIG. 4, the step of dividing data files into first and second groups (S100) may include searching for a memory (S110). If the database is not created according to the media transfer protocol (MTP), the control unit 180 can search the memo 160.

Next, a step of extracting a data file (S120) may be performed. For example, the control unit 180 may sequentially extract the data files stored in the memory 160 using a hierarchical structure such as a directory. The order of extracting the data file can be set in various ways.

Next, step S130 of comparing the extension list with the extension of the data file may be performed. The data file extracted by the control unit 180 may include an extension. The extension can be a string immediately followed by the file name to indicate the type of file. These extensions can indicate the attributes of the data file or the program that created the file.

The control unit 180 may compare the extension of the extracted data file with the extension list. At this time, the extension list may include at least one reference extension. The reference extensions may be a reference for specifying files to which update priorities are assigned among the data files stored in the memory 160. For example, the control unit 180 can compare and determine whether the extension of the extracted data file is included in the extension list.

 In addition, the list of extensions can be further divided into at least one of a list of video, audio, and image extensions. Thus, the control unit 180 may use at least one of the video, audio, and image extension lists to compare whether the data file corresponds to at least one of a video, audio, and image extension list.

In this case, when comparing the extension of the data file with the extension list, the controller 180 may compare the extension of the data file according to the comparison order of the reference extensions included in the extension list. For example, the comparison sequence can be set at the factory. Such a comparison sequence may be changed after the factory shipment, using an operating system update, or the like or by user input. The comparison order of the reference extensions will be described below with reference to FIG.

Next, according to the comparison result, step S140 may be performed in which the first and second groups are distinguished. The control unit 180 compares the extension list with the extension of the data file, and divides the data file into one of the first and second groups according to the comparison result.

For example, if the extension list includes one criterion extension ("avi"), files with extensions "avi" of the data files stored in the memory 160 are included in the first group, The files that they contain may be included in the second group.

Also, since the list of extensions can be further divided into at least one of video, audio, and image extension lists, the control unit 180 may use at least one of the video, audio, and image extension lists to convert the data file corresponding to the first group into video , Audio, and a set of images.

Next, if another data file exists, the process returns to step S120 of extracting the data file, and if not, step S100 of dividing the data files into the first and second groups may end. That is, the above-described steps S120 to S150 may be repeated until all the data files stored in the memory 160 are divided into the first and second groups.

Although it is not shown in the drawing, when the step of dividing the data files into the first and second groups (S100) is ended, the link information of the files included in the first and second groups is next divided into the first and second A step of storing the link list in a cache memory may be performed. In addition, the control unit 180 may store the directory information constituting the memory 160 as a third link list in the cache memory.

The mobile terminal 100 may output the update progress status to the display unit 151 when updating the data files stored in the memory 160 to the database. For example, the progress of the update may be output to the display unit 151 with a message such as "the progress rate is 49%."

According to the related art for outputting the update progress status, the mobile terminal 100 has to search the memory 160 several times in order to grasp the total number of data files stored in the memory 160. For example, the control unit 180 searches the memory 160 several times by executing a function such as "native_getNumFiles ()" Since the memory 160 is searched for redundantly, updating of the database is inevitably slowed down.

According to the present invention, the controller 180 may update the database using at least one of the first, second, and third link lists stored in the cache memory. In this case, the cache memory may mean a high-speed buffer memory used to reduce the difference in the access speed between the central processing unit and the main memory.

Also, the control unit 180 checks the update progress of the database using at least one of the first, second and third link lists (hereinafter "link lists") stored in the cache memory, And control the display unit 151 to guide the user to the progress of the update.

Since the link lists may include all necessary information related to the data files stored in the memory 160, the controller 180 may update the database using the link lists stored in the cache memory have. Therefore, according to the present invention, the mobile terminal 100 can search the memory 160 only once, update the database, and output the progress of the update to the display unit 151. Accordingly, the update processing speed can be increased as compared with the conventional technique of searching the memory 160 several times.

5 is a diagram for explaining a list of extensions according to an embodiment of the present invention.

Referring to FIG. 5, the extension list may include at least one of a video extension list 210, an audio extension list 220, and an image extension list 230. Although the extension list is shown as being divided into video, audio, and image extension lists 210-230, it may be set as one extension list without distinguishing it.

The criterion extensions of the extension list can be set in a comparison order. Then, the control unit 180 can compare the extension of the data file with the extension list according to the comparison order. For example, the control unit 180 may compare video, audio, and image extension lists in order, and compare them in index order when compared with a video extension list. For example, referring to FIG. 5, "avi", "mp4", "asf", ... , "mov" in that order.

At this time, by changing the comparison order, it is possible to shorten the time for dividing the data files into the first group and the second group. For example, when the controller 180 has finished updating the database, the controller 180 may store the update history in the memory 160. At this time, if the data file corresponding to "mp4" is larger than the data file corresponding to "avi", the order of comparison of the extension list can be changed from "avi" to "mp4" in order of "mp4" have. In another example, the terminal manufacturer may examine extensions used as data files of the mobile terminal 100, and may change the order of comparison of the reference extensions in order of the extensively used extensions.

6 is a block diagram illustrating a mobile terminal that updates a database according to an embodiment of the present invention.

Referring to FIG. 6, there is shown a block diagram illustrating an embodiment 300 according to a media transfer protocol (MTP) and embodiments 400, 500 according to the present invention. According to the embodiment 300 according to the media transfer protocol (MTP), the application using the media file can not be executed until the update of the database is finished.

According to an embodiment 400 in accordance with the present invention, once the update to the first group is finished, all applications can be executed. According to another embodiment 500 according to the present invention, for example, at least one of a group of video, audio and image files may be sequentially updated in the database. In this case, once the update of each file group is completed, an application using the completed file group can be executed. In addition, the controller 180 may control the display unit 151 to guide the completed file group to the user when the update of each file group is completed.

As described above, the first group can be divided into at least one of a group of video, audio, and image files. At this time, the control unit 180 may update the video, audio, and image file groups to the database based on the predetermined order. Such a predetermined order may be changed by user input. Contents related to the predetermined order will be described below with reference to Figs. 7 and 8. Fig.

7 to 10 are views illustrating an example of a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 7, there is shown a mobile terminal 100 scanning a memory. After the booting is completed, the mobile terminal 100 may scan the memory mounted in the main body. The scan may mean updating the link information on the data files stored in the memory to the database. At this time, for example, the memory may be an SD card or the like as a flash memory.

In accordance with the present invention, the controller 180 may scan a data file stored in a memory in a media scan mode and a nonmedia scan mode. For example, a media scan refers to a database update for data files corresponding to at least one of video, audio, and image formats, and a nonmedia scan refers to other data files May be referred to as a database update.

That is, the control unit 180 may divide the data files stored in the memory 160 into first and second groups, and update the first and second groups sequentially to the database. In addition, the control unit 180 can further divide the first group into at least one of video, audio, and image groups, and update the video, audio, and image groups according to a predetermined sequence.

At this time, the user can change the predetermined order by using the media scan setting 610. [ When a user input to the media scan setting 610 is detected, the control unit 180 may output a predetermined order to the display unit 151. [ For example, referring to FIG. 7, the predetermined order may be a video, audio, and image population order 620, 630, 640.

If a user input whose group of images is the highest priority of the update is detected, the control unit 180 sets the predetermined order to the image, video and audio group order 640, 620, 630 in the video, audio and image group order 620, 630, 640 Can be changed. When the change is completed, the control unit 180 may update the first group to the database using the changed order. The method of changing the predetermined order can be implemented in various ways.

Referring to FIG. 8, there is shown a mobile terminal 100 that sets up a media scan. And options for changing the predetermined order can be output to the display unit 151. [

The control unit 180 may store the execution history in which the applications are executed in the memory 160. [ The execution history may be at least one of the number of executions of each of the applications, the number of the first execution after updating the database, and the number of the first execution after the mobile terminal 100 is unlocked. The control unit 180 can change the predetermined order based on the execution history of the applications stored in the memory 160. [

Also, the control unit 180 may calculate the number of files of the files included in the video, audio, and image file groups, respectively, and change the predetermined order based on the number of files. If the database is updated in the order of file groups having a small number of files, updating of a group of files having a small number of files can be completed quickly. For example, if the number of video files is 1 and the number of audio files is 100000, an application using a video file can be executed quickly by updating from a group of video files. The control unit 180 may update the database in the order of file groups having a large number of files.

At this time, if a user input is received for any one of "the order of the most-executed applications", "the order of the applications first executed", and "the order of the applications capable of quick execution" The predetermined order can be changed.

FIG. 9 shows a mobile terminal 100 that informs a user of the progress of the update using the display unit 151. FIG.

Referring to FIG. 9A, a home screen screen may be displayed on the display unit 151. FIG. At this time, the controller 180 checks the update progress status using at least one of the first, second and third link lists stored in the cache memory, and displays the update progress status on the display unit 151. [ . The update progress may be a database update progress, an update progress for the first group, an update completion of at least one of video, audio and image groups, and so on.

For example, the controller 180 may output an update progress status to the indicator area 660 at the top of the home screen. For example, referring to FIG. 9B, the controller 180 may output an update progress status using a pop-up window.

9 (c), the controller 180 may output an application that can be used and an application that can not be used differently depending on the update of the database on the display unit 151. [ For example, if an update to a video group has been completed, an update to a group of images is in progress, and an update to the audio population has not begun, then at least one of the image and audio files The application can not be executed. At this time, the controller 180 can adjust icon transparency of applications that can not be executed. For another example, you can output an image that directs an unexecutable fact to an icon in an application that can not be executed.

Referring to FIG. 10, a mobile terminal according to an embodiment of the present invention is illustrated. The display unit 151 may output the progress of the database update. For example, the controller 180 calculates an update progress rate using the total number of data files stored in the memory and the total number of data files updated in the database, and updates the calculated update progress rate And output it to the display unit 151.

When the update of at least one of the video, audio, and image files having the priority order is completed, the control unit 180 may output the completed message to the display unit 151 in the form of a message. For example, referring to FIG. 10, at the same time that updating of the video group is finished, the control unit 180 outputs a message to the display unit 151 that the application related to the video (or moving picture) can do. In this manner, the control unit 180 can output a message to the display unit 151 about the updated group every time the update step is completed.

Referring to FIG. 10, it is shown that video, audio, and image files are updated in the order of collection. However, the update order may be changed as described above with reference to FIG.

Although not shown in the drawings, according to the present invention, the control unit 180 may be configured so that the application using the data file included in the first group is executed before the update to the second group is completed, Can be sequentially updated in the database. Thus, while an application using at least one of the video, audio, and image files is running, the data size of the database may continue to increase. In addition, while an application using at least one of the video, audio, and image files is running, an insert log that inserts data into the database may be created.

Also, the memory 160 can be detachably attached as a flash memory. During the update of the database, if the memory 160 is detached by the user or for some other reason, the control unit 180 can return the database to its original state (rollback). According to the database rollback function, if the detached memory 160 is attached again, no error may occur.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention.
