System of searching and playing music using metadata in multi-media and method

The present invention relates to sound source search reproduction, and more particularly, to sound source search and reproduction using metadata.

The invention regarding a music retrieval method using metadata is known from Korean Patent Publication No. 10-2008-0090016. The music search method using this metadata displays at least one or more of categories, sub-categories, and items on the display screen of the portable media player, and selects one of the metadata of the category or the metadata of the sub-category. By displaying the items of or items of metadata related to the selected metadata on the display screen, the number of steps of selecting a category can be reduced, and selection of all the metadata of the category can be made, thereby broadening the user's selection.

Meanwhile, the necessity of a method of conveniently searching for and controlling music desired by the user is continuously required according to the type of media player and the capacity of the storage medium.

The present invention provides a technical method for creating and playing a playlist that matches a user's preference regardless of a storage location of a sound source or a type of media player in an integrated multimedia system environment in which various sound source devices and a music player are connected such as a vehicle. The purpose.

In accordance with an aspect of the present invention, a sound source search and playback system using multiple metadata according to an aspect of the present invention includes metadata of sound sources distributed in a database in which metadata is stored, sound storage media, and media players. Player control modules for extracting and storing in the database, a database search module for searching a sound source list corresponding to a sound source search condition input from a user, a playlist generation module for generating a playlist for the searched sound source list, And a main control module configured to control playback of the corresponding sound source through the corresponding player control module according to each sound source storage position when playing the sound source of the playlist. Here, the metadata includes artist, album, title, and genre information.

On the other hand, the sound source search and playback method in the multi-media using the metadata according to an aspect of the present invention for achieving the above object is the step of extracting the metadata of the sound sources distributed in the sound storage medium and media players, Storing the extracted metadata in a database, retrieving a sound source list corresponding to a sound source search condition input from a user, generating a playlist for the searched sound source list, and playing a sound source of the playlist And controlling the corresponding sound source to be played through the media player according to each sound source storage position.

The present invention creates an effect that the user can conveniently search and play, even if the sound source desired by the user is distributed to various media or media players.

BRIEF DESCRIPTION OF THE DRAWINGS The foregoing and further aspects of the present invention will become more apparent from the following detailed description of preferred embodiments with reference to the accompanying drawings. Hereinafter, the present invention will be described in detail to enable those skilled in the art to easily understand and reproduce the present invention.

1 is a block diagram of a sound source search and playback system in a multi-media using metadata according to an embodiment of the present invention.

As shown, the sound source retrieval and playback system in the multimedia includes a database with media players 100-1, ..., 100-n and player control modules 200-1, ..., 200-n. 300, a user input unit 400, a database search module 500, a playlist generation module 600, and a main control module 700. The media players 100-1,..., 100-n play back a sound source, for example, iPod, June, and the like. The player control modules 200-1, ..., 200-n control playback of sound source storage media such as USB, SSD and / or media players 100-1, ..., 100-n. The module in charge. The player control modules 200-1,..., 200-n also extract metadata of sound sources distributed in sound storage media and / or media players and store the metadata in the database 300. . Here, the metadata of the sound source includes information on an artist, an album, a title, a genre, and the like.

The user input unit 400 is a component for receiving a sound source search condition from a user. In one embodiment, the user input unit 400 includes one or more input means of key input, touch input, and voice input. Therefore, the user can input the condition of the sound source to be listened to through a key, a touch, or a voice. The database search module 500 searches the database 300 and extracts a list of sound sources corresponding to a sound source search condition received from the user input unit 400. The sound source search condition is mapped to the metadata content and used to extract a list of specific sound sources. The playlist generation module 600 generates a playlist for the sound source list extracted by the database search module 500. The playlist according to the sound source search condition is illustrated in FIG. 2. FIG. 2 shows a playlist created as a result of a search in media such as DVDP, iPod, USB, Juke, etc., mounted in a vehicle when the user inputs a sound source search condition of “Play Artist Girs Generation”.

The main control module 700 controls the medium or player control module in which the sound source is located while traversing the playlist generated by the playlist generation module 600 and plays a main control role of reproducing the corresponding sound source. In addition, the main control module 700 stops the playback of the player control module when changing the sound source to be played, and controls the media or the player control module in which the new sound source is located to play.

3 is a flowchart illustrating a method for searching and playing a sound source in multiple media using metadata according to an embodiment of the present invention.

The player control modules 200-1,..., 200-n are sound storage media such as USB, SSD, and / or sound sources distributed in the media players 100-1,..., 100-n. Extract metadata about the fields (artist, album, title, genre), and configure the database 300 with the extracted metadata (S100) (S200). The user input unit 400 receives a search condition for a sound source that the user wants to hear (S300). When the sound source search condition is input, the database search module 500 searches the database 300, extracts a list of sound sources corresponding to the sound source search condition, and delivers the list to the playlist generation module 600, and the playlist generation module 600. ) Generates a playlist for the extracted sound source list (S400) (S500). The main control module 700 communicates with the corresponding player control module according to the storage position of the sound source in the playlist to perform playback of the sound source (S600). After the reproduction of the sound source of the currently playing player control module is completed, the main control module 700 receives an event indicating that the reproduction of the sound source needs to be changed from the player control module (S700). The main control module 700 checks whether there is a sound source to be played in the playlist, and if there is a sound source to play, changes to the corresponding player control module according to the storage position of the sound source and plays the sound source (S800).
