The present invention relates to a method for providing a multimedia file, and more particularly, to a method of operating a multimedia file providing server for allowing a user to selectively play a plurality of multimedia contents using a new file in which a plurality of multimedia files are combined. It relates to a multimedia providing server employing.

Recently, with the development of the high speed data communication network, many people are using the Internet, and with the increase of the use of the Internet, users can easily access various multimedia files.

The user can access a predetermined multimedia file providing server at any time from the client terminal via the Internet, and can easily download the multimedia file from the server. For example, the user may download an MP3 file, which is a multimedia file, from the multimedia data providing server, and when the user downloads the MP3 file, the user may play and listen to the MP3 file downloaded to the client terminal whenever the user desires.

Generally, MP3 files, which are multimedia files, contain both accompaniment and voice. When users of such MP3 files want to listen to only the accompaniment in the MP3 file to practice the song, there is no way to solve this problem in the MP3 file including both the accompaniment and the voice.

In order to solve this problem, Korean Laid-Open Patent Publication No. 10-2004-0103683 proposes a configuration for separating accompaniment and voice by removing the voice signal from the music signal output from the sound player. The Korean Laid-Open Patent has the advantage that only the accompaniment can be output by removing the voice signal from the output signal, but other audio signals are left intact, and only the voice signal can not be precisely removed. If you want to play back a voice or accompaniment or accompaniment, there is no way to solve it.

Accordingly, a method for allowing a user to selectively play contents corresponding to a plurality of multimedia files is provided, and a method for more convenient use of the multimedia file by the user is urgently required.

The present invention has been made to solve the above-described problems of the prior art, by providing a multimedia file that allows a user to use a multimedia file more conveniently by selectively playing a plurality of multimedia content using a single multimedia file. An object thereof is to provide a server operating method and a multimedia file providing server employing the method.

It is done.

In this case, the content of another format for the first multimedia file may contain the same content as the content of the first multimedia file, but may be different in form. At this time, the first multimedia file and the second multimedia file may have the same content title. In addition, the first multimedia file and the second multimedia file may have the same playback time.

For example, when the first multimedia file is an MP3 file containing a voice and a performance of a singer who sang a specific song, the second multimedia file may be an MR file containing only a performance without a voice of the singer for the same song. For example, when the first multimedia file is a foreign currency video, the second multimedia file may be a Korean dub video of the foreign currency. For example, when the first multimedia file is a music file in which a song entitled "Moonlight" is played on a piano, the second multimedia file may be a music file in which the same song is played on a violin.

In this case, the second multimedia file may be two or more. For example, when the first multimedia file is a French movie video, the second multimedia file may be a Korean dubbing video and a Japanese dubbing video of the French movie.

In addition, the operating method of the multimedia file providing server according to another embodiment of the present invention, the operating method of the multimedia file providing server, the step of receiving a query for requesting a synthetic multimedia file corresponding to the predetermined identification information from the client terminal ; Selecting at least one second multimedia file corresponding to the first multimedia file corresponding to the identification information and content of another format for the content of the first multimedia file; Synthesizing the first multimedia file and one or more second multimedia files to generate the synthesized multimedia file; And transmitting the generated synthetic multimedia file to the client terminal.
