A method for playing a file using history in a digital media player comprises: sorting files stored in a memory based on a set sorting condition to generate the sorted file list(100); selecting files to be played and playing the files(102); storing a sorting standard of each file and an index number(104); generating a history list based on the sorting standard and the index number(106); generating the sorted file list by using the sorting standard and playing the file of the selected index number(110); selecting the file from the sorted file list(112); and playing the selected file(114).

Description

Method for playing file using history list in digital media player}

1 is a flowchart illustrating a file reproduction method using history in the digital media playback apparatus according to the present invention.

The present invention relates to a file playback method using a playback history in a playback device. More specifically, a digital media player such as an MP3 player records a sorting environment applied to a corresponding file for each file in a history list. When selecting and playing a file from the list, restore the file list of the sorting environment of the file, and use the history of the digital media player that has improved the utilization of the device to easily select and play another file in the same sorting criteria. A file playback method.

Digital media players, such as MP3 Player, which store audio and music files in memory, and can easily play files as needed, allow users to store more songs than conventional audio cassette players. It is developed as a model of various functions.

In such a digital media player, a file is sorted according to a sorting standard set by a user, for example, a file creation date or a song title, and then selected and played. In addition, according to the model, a history list of the reproduced files is recorded so that the user can select the corresponding file among them and simply replay the previously reproduced file.

However, in the conventional history list, only files that have been simply reproduced are listed, and there has been a demand for a reproducing method in which a user increases utilization of the device by using sorting information associated with each file of the history list.

The technical problem of the present invention is to generate a history list in which a sorting environment for each file that has already been played is stored, and when a file is selected in the history list, the corresponding file is played, and the file list is generated according to a condition previously sorted for the file. The present invention provides a method of playing a file using history in a digital media player that has been restored to increase the utilization of the device.

File playback method using the history in the digital media playback apparatus according to the present invention for achieving the above technical problem,

Generating a list of sorted files according to a sorting criterion set by a user;

When the user selects a desired file from the sorted file list, playing the file and storing a sorting environment applied to the file in a history list; And

And selecting a file from the history list, playing the file, and sorting the file list into a sorting environment applied to the file.

The sorting criteria may be set to one of a file creation date, a mood of a music file, and a title name.

The history list may include a file name, a sorting criterion, and an index of a file.

The method may further include selecting and playing another file desired by the user on the file list sorted by the sorting environment applied to the corresponding file.

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

1 is a flowchart illustrating a file reproduction method using history in the digital media playback apparatus according to the present invention.

In FIG. 1, a sorted file list is generated by sorting files stored in a memory of a digital media player according to a sorting condition set by a user (step 100). Table 1 below shows the file list before sorting.

In step 102, the user selects a file to be played from the sorted file play list and plays the file.

Table 2 shows an example of selecting a specific file of index 9 as a list of files sorted based on a title in the file list of Table 1.

The list of files selected according to a predetermined sorting criterion may be sorted in ascending or descending order according to the alphabetical order of the first letter of each file title, and if the sorting criterion is the creation date when the file is created, You can also sort in descending order.

Steps 104 and 160 store the sorting criteria and the corresponding index number for each sorted and reproduced file, and generate a history list with the sorting criteria and the index number of each reproduced file.

When a file is selected in the history list, a sorted file list is generated using the sorting criteria of the file, and the corresponding file of the selected index number is played (steps 108 and 110). If the user selects a specific file from the history list for playback, the file list is sorted to the environment previously sorted to select the file (step 110).

Table 3 sorts the file list of Table 1 by the title as shown in Table 2, selects and plays the file list, and sorts the file list of Table 1 by the creation date based on the creation date. Shows a history list created when you select and play back.

In the history list of Table 3, when the file name "Loveholic-if you have.mp3" is selected and played back, the sorting criteria is the title. Thus, the sorted file list is generated as shown in Table 2.

If a file is selected from the sorted file list using the sorting information of the selected file among the files in the history list (step 112), the selected file is played (step 114).

In this case, as shown in Table 2, another file name may be additionally selected from the sorted file list based on the title to play the file. For example, in a file sorted by the title of Table 2, if the title of the song you want to play is "Pushing out Love", the title "Pushing out Love" index 7 on the file list sorted by title You can easily check, select, and play back.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.

According to the present invention, when playing each file sorted by a digital media player such as MP3 Player, the sorting environment of the corresponding file is recorded in the history list and the file is selected from the history list and played back. By sorting the file list, it is possible to easily select and play other files sorted under the same conditions, thereby improving the utilization of the digital media player.
