Description

A method for inserting the information into a MP3 file}

The present invention relates to a method of producing an MP3 file, and more particularly, to insert information extracted in the WAVE form into the first half, the second half, or the middle part of the original song, and to convert the information into an MP3 file to produce an MP3 file with information provided to the user. It is about a method.

In general, MP3 files are compact compressed music data files that maintain the sound quality of compact disks (CDs), and are becoming the next generation digital record media that succeed the record market line leading to LP record-tape-CD. In line with this, the MP3 record market, which is distributed on the Internet in the form of MP3 files, has also rapidly increased to emerge as the mainstream of the record market.

However, despite the fact that the main consumers of MP3 records are teenagers or 20s who do not have a credit card, the price of MP3 records in circulation is high and most of them must be purchased using credit cards, which hinders the activation of the MP3 market. There was a problem.

In addition, most of the advertising techniques used on the Internet are banner advertisements using visual graphic formats. These banner advertisements are one-time advertisements, and most Internet users are empirical in banner advertisements that fill the screen. Therefore, there was a problem that the advertising effect is very weak while paying expensive advertising costs.

Accordingly, the present invention has been invented to solve the above problems, the user can use the MP3 file free of charge by providing the MP3 file inserted with specific information, such as radio advertising (CM) free to the general user over the Internet It is possible for the advertiser to provide a method for producing an MP3 file inserted information that can maximize the advertising effect at a low cost.

In order to achieve the above object, the present invention provides a first step of extracting the original song and the specific information stored in the storage medium in the WAVE form, and the information extracted in the WAVE form in the first step using a sound editor And a third step of inserting the first half, the second half, or the middle half, and a third step of converting a WAVE file into an MP3 file through an encoder when information is inserted into the original music in the second step.

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

1 is a diagram schematically illustrating a network environment to which the present invention is applied, and a plurality of user units 21 to 23 are connected to an operator unit 10 through a network 30, and the operator unit 10 is connected to the operator unit 10. An MP3 database 11 for storing an MP3 file into which specific information is inserted is provided.

Therefore, when any user unit 21 connects to the operator unit 10 via the network 30 and requests the transmission of a specific MP3 file, the operator unit 10 may download the corresponding MP3 file stored in the MP3 database 11. Transfer to the user unit 21 via the network 30.

In this case, the user does not pay the cost of downloading the MP3 file, and as shown in FIGS. 4A to 4C, specific information such as a radio advertisement (CM) is inserted in the first half, the second half, or the middle half of the downloaded MP3 file.

On the other hand, the operator unit 10 for providing the user with the MP3 file with the specific information is inserted into the network interface for connecting the user unit 21 to 23 and the operator unit 10 through the network 30 as shown in FIG. (15), which is connected to the main processor (16) which controls all operations of the operator unit (10).

In addition, the main processor 16 has a sound editor for extracting the specific information and the original song input as a line from the CD or MD (Mini Disk) in the form of WAVE, and combines the extracted specific information with the original song to store as a WAVE type file ( 13) and an encoder 14 for converting a WAVE file in which information and original music are combined into an MP3 file.

In addition, the main processor 16 temporarily stores the work file in the buffer 12, and the speaker (SP) through the sound card 17 to the WAVE-type file combined with the information and the original song so that the operator can determine whether there is an abnormality ) In addition, the main processor 16 stores the MP3 file in which the information and the original music are combined in the MP3 database 11 so as to be provided at the request of the user.

Next, a method of producing an MP3 file in which specific information to be provided to a user is inserted will be described in detail with reference to FIG. 3.

In order to produce an MP3 file to be provided to the user, specific information must be inserted into the original song. For this purpose, the original song stored in the CD or MD is extracted in a WAVE form without deterioration of quality (110). At this time, the original music stored in CD or MD is extracted in the form of WAVE using freeware such as CD Ripper or by using a manually programmed compression codec.

As described above, the original song is extracted in the WAVE form, and specific information to be inserted into the extracted original song, for example, a radio advertisement CM, is also extracted in the WAVE form (120). Advertisement can be provided from the advertiser in the form of tape or MD. If the advertisement is provided in the form of MD, the advertisement track can be set and the desired advertisement can be entered into the line of the operator unit 10 and saved in the WAVE form. do.

On the other hand, when the advertisement is provided in the form of a tape to play the tape using a general component and input it to the line of the operator unit 10 as described above to store in the WAVE form. Typically, a song of about 4 minutes is stored as 40Mbytes of data at 128Kb 44.1KHz, and an advertisement of about 1 minute is stored as 10Mbytes of data.

As such, when the original song and the advertisement are extracted in the form of WAVE, the main processor 16 inserts the advertisement into the first half, the second half, or the middle half of the original song using the sound editor 13 (130). In this case, a delay time of about 0.5 seconds to about 1.0 seconds is inserted into the front and rear of the inserted advertisement so that the original music and the advertisement are distinguished, and the total advertisement time is about 16 seconds including the delay time.

When the advertisement is inserted into the original song as described above, the main processor 16 executes a WAVE type file and outputs it to the speaker SP so that an operator can check whether there is an abnormality. If there is no abnormality in the edited WAVE file, the main processor 16 converts the WAVE file into an MP3 file through the encoder 14 (140). Again, using WWW or using a custom-programmed utility, WAVE files are encoded into MP3 files.

Meanwhile, in order to commercially distribute MP3 digital recordings over the Internet, the MP3 file illustrated in FIGS. 4A to 4C having advertisements inserted therein is adopted as a copy protection system and is legalized to distribute recordings in a secure state. After encrypting the MP3 file using an existing copy protection system such as SecuMAX (Samsung Electronics), which is an encryption system, the completed file is stored in the MP3 database 11 and provided according to a user's request (150). To 160).

Although the above-described embodiment describes only an MP3 file, those of ordinary skill in the art can apply the present invention to a video file that can simultaneously watch music and images through Real Player. You will notice.

As described above, if MP3 files with specific information, for example, radio advertisements (CM), are provided for free through the Internet, users can use MP3 files for free, and advertisers can target ads to specific classes at low cost. It can maximize the advertising effect.

In other words, unlike a one-time banner ad, every time you listen to a song in an MP3 file, you must also listen to the inserted ad. The effect is maximized.

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