In particular, the portable terminal has a built-in multimedia player (eg, MP3 player, media player) function that can play multimedia objects such as music files or video files. Currently, the multimedia player uses multimedia data of each multimedia object to have multimedia information having the same information by item (eg, Genre, Artist, Album, Track, etc.). It provides a function to classify objects and automatically create a playlist. Here, the meta information refers to data describing the multimedia object.

The function of creating a playlist using the meta information automatically creates a playlist for each specific item without a user's separate key operation, so the user selects only the type of the item to be played, thereby selecting the selected item. Related playlists can be created as shown in FIG.

When the user selects to delete a specific multimedia object from the playlist created using the meta information, the multimedia object itself is deleted and deleted from the database as well as the playlist. Therefore, all items created using the meta information are deleted from the playlist. For example, when deleting "Instant Cafe" and "Romantic Generation" from a playlist for an artist item as shown in FIG. 1 (a), as shown in FIG. In addition to being deleted from the artist playlist, the album playlist and the genre playlist are also simultaneously deleted, unlike the user's intention.

Therefore, if the user does not want to play a specific multimedia object only for a playlist of a specific item created by using the meta information, the user must adjust the object not to be played every time or select the desired object manually. There is a problem with creating a playlist.

SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus and method for generating a multimedia object playlist in a portable terminal.

Herein, the portable terminal means all terminals capable of playing multimedia objects, such as the controller 200, the playlist generation unit 202, the input unit 204, the storage unit 206, the voice processing unit 208, and the speaker ( 210, a display unit 212.

Referring to FIG. 2, first, the control unit 200 performs processing and control for voice call and data communication of the portable terminal, and in particular, the play list generation unit 202 is provided according to the present invention. When a list generation event is generated, a classification item for generating a playlist is input from the input unit 204 and received using the meta information of each object from a database of a multimedia object of the storage unit 206. Search for multimedia objects corresponding to the category. Thereafter, a playlist is composed of only the multimedia objects except for the multimedia objects in which the meta flag corresponding to the category is selected among the searched multimedia objects. Here, the meta flag means a flag for indicating that the multimedia object is excluded from the playlist for the specific category when the playlist is generated for the specific category.

The input unit 204 is provided with a plurality of function keys to provide the control unit 200 with data corresponding to a key pressed by the user.

The storage unit 206 may include a program memory, a data memory, a nonvolatile memory, and the like. The program memory stores a program for controlling the overall operation of the portable terminal. The program memory may use a flash memory. The data memory temporarily stores data generated during the operation of the terminal. The data memory may use random access memory (RAM). The nonvolatile memory stores system parameters and other storage data, such as telephone numbers, photos, music files, video files, and the like. Further, according to the present invention, a multimedia object database such as the music file and the video file is stored. As shown in FIG. 3, the database includes identification (301), meta data (303), meta object body (305), and meta flag (Meta Flag) of each multimedia object. (307). Here, the ID 301 means an identification code for distinguishing each multimedia object, and the metadata 303 indicates information of each multimedia object, for example, information such as genre, artist, album, etc. The meta object body 305 represents actual data of each multimedia object. In addition, the meta flag 307 refers to a flag indicating whether to exclude a corresponding multimedia object from a playlist for a specific category.

The voice processing unit 208 may be referred to as a voice codec, and performs a function of performing input / output processing of a voice signal through the microphone and the speaker 210. For example, the PCM (Pulse Code Modulation) data provided by the controller 200 is converted into an analog voice signal and transmitted through the speaker 210, and the voice signal applied from the microphone is converted into PCM data. Provided to the controller 200.

The display unit 212 displays status information generated during operation of the portable terminal and limited number of characters. In particular, according to the present invention, the playlist input from the controller 200 is displayed.

4 illustrates a procedure of generating a playlist using meta information of a multimedia object in a portable terminal according to an exemplary embodiment of the present invention.

Referring to FIG. 4, first, in step 401, the portable terminal checks whether an event for viewing a playlist for each item is generated. When an event for viewing a playlist for each item is generated, the portable terminal determines whether a specific category for generating a playlist is selected by a user's key manipulation (403). For example, it is checked whether a category such as "rock" or "Other" is selected in the genre item or a category such as "Avril lavgne" or "Instant Ronantic Floor" in the artist item.

When the specific item is selected, the portable terminal generates a playlist for the selected category in step 405 and displays it on the display unit 212. Here, the portable terminal can generate the playlist by checking the metadata of each object in the multimedia object database of the storage unit 206 and searching for multimedia objects corresponding to the selected category. For example, when a user requests to display a playlist of music files whose genre is "rock", the portable terminal checks the metadata 303 in the multimedia object database so that the genre is "rock". After creating a playlist with the multimedia objects, the generated playlist is displayed.

In step 407, the portable terminal checks whether a menu for viewing the metadata 303 of the specific multimedia object is selected from the displayed playlist by the user's key manipulation. When the metadata view menu of the specific multimedia object is selected, the portable terminal reads out the metadata 303 of the selected multimedia object from the storage unit 206 and displays it on the display unit 212 in step 409. . For example, as shown in FIG. 5, when a menu for viewing metadata of "Instant Cafe" is selected in a playlist, metadata of "Instant Cafe" is "1.Artist-Instant Romantic Floor 2." Album-1st Instant Romantic 3.Genre-Other "can be displayed.

Thereafter, in step 411, the portable terminal checks whether a menu for excluding the multimedia object from the playlist is selected when a specific category is selected from the displayed metadata to generate a playlist for the specific category. When a menu for excluding the multimedia object from the playlist is selected, the portable terminal plays the multimedia object with respect to the specific category using the meta flag 307 of the meta information of the multimedia object in step 413. Record the exclusion from the list and save it.

In step 415, the portable terminal checks whether an event for playing a specific multimedia object or regenerating the displayed playlist is generated. When the event occurs, the portable terminal checks the meta data in the multimedia object database of the storage unit 206 in step 417 to search for the multimedia objects corresponding to the selected category again, and then executes the search. The meta flag 307 is checked to generate a playlist using the remaining multimedia objects except for the multimedia objects indicated to be excluded from the playlist for the selected category. In step 419, the portable terminal displays the generated playlist on the display unit 212. Here, the portable terminal may generate a playlist excluding the multimedia object to be excluded by the user by regenerating the playlist for the specific category using the meta flag 307. Also, by excluding the multimedia file only from the playlist for the particular category, the playlist for the other category is not affected. For example, as shown in FIG. 6 (a), when the artist excludes "Instant cafe 601" and "Romantic Gentleman 603" from the playlist of "Instant Romantic Floor", FIG. 6 (b) As shown in Figure 6, the excluded objects 601 and 603 are deleted only from the artist playlist and are included in the playlist for the album or genre.

Thereafter, the portable terminal terminates the algorithm according to the present invention.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the scope of the following claims, but also by the equivalents of the claims.

As described above, the present invention does not include the multimedia object in the playlist only for a specific category by using the metadata of the multimedia object in the portable terminal, so that only the desired multimedia object is selected and the playlist is not generated. However, it is possible to reflect the user's intention only for the playlist of a specific item without affecting the playlist for other items while maintaining the characteristics of the playlist generated by the classification.
