Abstract

PROBLEM TO BE SOLVED: To enable a user to enjoy information distributed via a network or downloaded multimedia contents of music, etc., without being aware of trouble for network connection. SOLUTION: A file begins to be downloaded (S211), the storage destination of the downloaded file is specified (S212), and only the register corresponding to vocals begins to be deleted from sequentially read-in files (S213). After the downloading is completed (S214), files having the vocal register deleted are stored in a downloaded data storage area. Therefore, even a file containing vocal information can be stored as a file for KARAOKE. Further, the operator of a Web server when providing this service can save the trouble to specially generate KARAOKE data.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a download system, an information processing apparatus, and a recording medium.

[0002]

BACKGROUND OF THE INVENTION Today, with the development of communication technology and the improvement of communication infrastructure, distribution services and download services of various multimedia contents by e-mail, Internet connection, and the like have become widespread. Also,
Apart from this, applications specialized in multimedia, such as playing and editing music downloaded in a data format such as MP3 and processing images on a personal computer, are also becoming widespread.

[0003]

However, as described above,
Even if the network environment and applications controlled and executed by personal computers have become widespread, it is necessary to be aware of this when connecting to the Internet under the current situation, and it is troublesome for PC users to enjoy multimedia contents. There was something to feel. The present invention has been made in view of such a problem, and allows a user to enjoy information distributed from a network or multimedia contents such as downloaded music without being bothered by a network connection. It is an object of the present invention to provide a download system, an information processing device, and a recording medium that can be used.

[0004]

According to a first aspect of the present invention, there is provided a download system, comprising: a server for managing a database for storing music data including voice; In a download system including a terminal that downloads and stores song data from the database via a network by connecting, the terminal includes a deletion unit that deletes the voice from the downloaded song data. Therefore, even if a song containing audio information is downloaded, the terminal can automatically generate and store song data composed of karaoke music without audio information.

[0005] In the information processing apparatus according to the second aspect of the present invention, a connection means for connecting to a server via a network, and the connection means connects to the server, so that the server is connected to the server. And a determining means for determining whether or not the song data downloaded by the downloading means includes a voice, and the determining means includes a voice. And a deleting unit for deleting the voice.

Therefore, according to the invention described in claim 2, it is possible to function as a terminal in the download system according to the invention described in claim 1. Therefore,
A terminal capable of constructing a system that can automatically generate and store song data composed of karaoke music that does not include voice information even if the user downloads a song that includes voice information. Can be provided.

In the recording medium according to the third aspect of the present invention, a connection procedure for connecting to a server via a network, and the connection procedure connects to the server, so that the connection is established via the server. In a computer-readable recording medium storing a program for causing an information processing apparatus to execute a download procedure for downloading song data from a database, a determination to determine whether or not the song data downloaded by the download procedure includes sound. A program for causing the information processing apparatus to execute a procedure and a deletion procedure for deleting the voice when it is determined that the voice is included in the determination procedure is recorded.

[0008] Therefore, according to the recording medium of the third aspect, by causing a computer to read the recorded program, the computer can easily function as the terminal of the invention according to the first aspect. Therefore, even if a song containing audio information is downloaded, a system is constructed that allows the terminal to automatically generate and store song data composed of karaoke music without audio information. Terminals that can be provided can be easily provided.

In the present embodiment, the operator of the Web server 2 supplies the service registrant with “Karaoke data download service” as one of the service contents. In this case, the DB 272 for managing the database 6 of the Web server 2
"Other accompanying data" includes the download destination PC5
Is set as a karaoke file icon as a program for deleting only the vocal range at the time of downloading, lyrics information, and icon information. In such a service, the display unit 60 of the PC 5 displays FIG.
When "Karaoke" is specified while the screen shown in Fig. 2 is displayed, the charge "￥
250 "is displayed, and the database 6 of the Web server 2 is displayed.
From the Web server 2 receiving the download of the file from the Web server 2 and the database 6 corresponding to the download-designated file.
The download of the file from Step 2 is started (Step S211). Next, storage destinations of these download files are designated (step S212), and when the download is started, at a stage where the download files are temporarily stored in the RAM 62,
The CPU 51 reads a program for deleting only the vocal range included in the “other accompanying data”, and starts deleting only the vocal range corresponding to the vocal from the sequentially read file (step S213). And
When the download is completed, (Step S21
4) As shown in FIG. 8B, the downloaded karaoke icon P20 is displayed, and the file from which the vocal range is deleted is stored in the download data storage area 554. Management information is registered in the download data storage management area 553.

According to this embodiment, even a download file containing vocal information can be stored as a karaoke file.
In addition, the operator of the Web server 2 can save the trouble of creating special karaoke data when performing such a service.

[0021]

As described above, according to the present invention, when music data is downloaded from a database via a network and stored by connecting to a server,
Deleting the audio from the downloaded song data Because the song is deleted, even if a song that contains audio information is downloaded, the terminal automatically stores song data that contains karaoke music that does not contain audio information. Can be generated and stored. In addition, when performing such a service, the server operator can save time and effort for creating karaoke data specially, and can reduce operating costs.
