The present invention relates to a media content service system through the Internet, and more particularly, to multi-channel music content broadcasting, which continuously transmits and listens to music of various genres including classics as main contents through the multi-channel for 24 hours through the Internet. It relates to a service system.

Listening to music in our lives can change moods, improve physical rhythms, and give us psychological stability. When listening to music personally, you can listen to music by inserting a music tape or music CD into a portable cassette tape recorder or compact disc (CD) device. On the other hand, if you are listening to music in public places such as subway and national railway stations, bus and port terminals, restaurants, medium and large bookstores, hospitals, pharmacies, video shops, hair salons and hotels, A small broadcasting room operated by the managers of the company uses a CD device or receives over-the-air broadcasts and amplifies it to transmit music. However, in the case of over-the-air broadcasting, news, broadcasting dramas, advertisements, etc., in addition to music, are organized together with music, and thus, over-the-air broadcasting may be inadequate for certain workplaces, public places, and many unspecified people. To this end, there is a small music cable broadcasting station that specializes in broadcasting only music. These specialty broadcasts transmit unspecified music genres to random or random workplaces, public places or unspecified people in the region because the broadcasting area is limited to the allocated area.

In recent years, with the development of digital communication technology and data compression technology, the high-speed Internet has been spreading all over the world, so that Internet real-time audio service converts and compresses the original music or sound source into digital data, transmits it, and plays music by downloading. Broadcasting service is utilized. Conventional over-the-air broadcasting services generally play music from recording media such as CDs or record recordings, whereas Internet audio broadcasting services use digital music data to repeatedly use the recording media in over-the-air broadcasting services. There is an advantage that can provide high quality music faithful to the original sound without degradation of sound quality that can occur.

Internet music stations convert music sources into digital data files and transmit them. These music files may be MIDI files produced by individuals. MP3 files are produced using audio compression algorithms of the Motion Picture Experts Group Audio Layer-3 (MPEG), which are suitable for transmitting a sound source to a computer. In particular, as MP3 files are downloaded from the Internet and reproduced by MP3-only players, they are widely used.

Unlike general public broadcasting, these real-time internet audio broadcastings, which have been made into a real media player as a web media tool, require a medium for accessing the Internet, so they are connected to the Internet rather than to the entire audience. It is being provided to individuals. For example, in an Internet music broadcast, individual users access their websites by using their computers, and then download music files of their choice from the list of music contents provided by the website, and then, in real time, It is made by listening to music by playing with. In addition, in order to broadcast the above-mentioned method to a specific place, region or business site or broadcast to all the unspecified members belonging to it, a small broadcasting room equipped with a computer and a music broadcasting facility operated by a manager of the place will be separately required.

As described above, unlike conventional real-time Internet music broadcasting services, in which individual users select music directly, they collect or belong to a specific place, area, or place of business having the same purpose. In order to meet the unspecified purpose, there is an urgent need for a system capable of listening to live music content for 24 hours without having a special broadcasting facility, and a broadcasting station and a multi-channel music content broadcasting service system capable of professionally servicing it. .

Therefore, the present invention is to provide a multi-channel music content broadcasting service system capable of professionally serving music for 24 hours for all unspecified people belonging to or belonging to a specific place or place of business in the industrial disaster. The purpose.

The web management module 210 provides various web pages including the homepage of the multi-channel music content broadcasting system 110 according to the present invention. The homepage provided by the web management module 210 performs authentication as a member to a user and provides various types of music contents and beneficial information related thereto to the authenticated member.

The web media module 220 uses a media tool program such as Winamp or Windows Media Player to allow the client computer 120 to receive and play music files such as MP3s. Broadcast plug-in programs that enable the broadcasting of music files, and server programs such as Shoutcast or Mycast that allow the client computer 120 to access the media server 140. do. The web media module 220 uses these programs to transmit the music files and the music-related contents provided through the respective music broadcasting channels to the client computer 120 at a speed of, for example, 256 kbps to 320 kbps by using a live broadcast method. send.

The compression control module 230 compresses a music file of digital data stored in the music database 150 into a file such as an MP3 file or window media audio (WMA) and transmits the compressed music file to the client computer 120. It performs the function. An MP3 file is an audio file that compresses sound source data of music by about 1/11 to 1/12 without degrading the sound quality by using audio data compression technology called MPEG audio layer-3. Ripper) is used to create wav format files and convert them to MP3 files using MP3 encoders. There are many applications for these MP3s. For example, unlike a method of storing music on CDs or cassette tapes, music files provided in MP3 format may be sold in units of songs through a computer network such as the Internet or PC communication. In addition, the ISDN (Integrated Service Digital Network) can be used to enjoy high-quality music that is higher than CD (Compact Disc) level, and can be used for digital audio broadcasting using satellite or real-time audio on demand (AOD) using the Internet. It is also possible.

WMA files are music files in the Windows Media Audio format from Microsoft, which can also be played with Windows Media Player or other media players. WMA files have a higher compression rate than MP3 files, and sound quality is as good as that of MP3 files.

In the present invention, since the data transmission capacity of each music broadcast channel is limited, when a user who has a right to use each music broadcast channel wants to access a music broadcast channel corresponding to the date and time to be serviced, traffic congestion may occur. This may cause the music file to be transferred to be cut off in the middle. In order to prevent this phenomenon, the compression control module 240 automatically adjusts the compression ratio of the music file of the digital data loaded from the music database 150 to be transmitted to the client computer 120.

For example, if the music broadcasting channel capacity is 160 Mbps, and the number of 500 or less people who receive music files by accessing the multi-channel music contents broadcasting system 110 of the present invention is given to all users as calculated by Equation 1 below: It will be able to deliver music files at transfer rates up to 320 kbps.

Baud rate = capacity of music broadcast channel / N

Where N represents the number of users.

However, when more than 500 users simultaneously access the multi-channel music content broadcasting system 110 of the present invention under the above conditions, music files transmitted at a maximum speed of 320 kbps are used at lower rates. Will be provided to Accordingly, the compression rate control module 230 of the present invention converts the sampling frequency of the music file extracted from the music database 150 and compressed using the following Equation 2 and Equation 3 to reduce the amount of data instead of reducing the amount of data. It is transmitted to the user at a transmission rate of up to 320 kbps.

Sampling conversion factor = capacity of music broadcast channel / (N × desired transmission rate)

Adjustable Sampling Rate = Current Sampling Rate × Sampling Conversion Factor

For example, the music broadcasting channel has a capacity of 160 Mbps, the number of users is more than 500, 600 people, and each of these users wants to transmit a music file at a desired transmission rate of 320 kbps, and the current sampling to compress the music file. Assuming that the rate is 8000 times per second, the sampling conversion factor obtained using Equations 2 and 3 is 0.83, and the adjusted sampling rate is 6640 times. Therefore, instead of reducing the amount of compressed data by reducing the sampling rate for compressing the music file, the music file transfer service can maintain 320 kbps constantly.

The ad insertion module 240 identifies the paid member and the free member by searching the user database 160 for information about the authenticated members through the web management module 210, and in accordance with the identification, the web media module 220 By selectively inserting the advertisement file extracted from the advertisement database 170 for each music content program unit transmitted to the client computer 120 by. The advertisement file inserted by the advertisement insertion module 240 may be an audio or video file, but the audio file is preferable in view of the purpose of providing music to the public through the audio amplifier / speaker 130. In addition, the content of the advertisement file may vary according to the location where the client computer 120 is disposed, that is, the channel where the same workplace for each sector in the whole country is single broadcast zone. For example, when the client computer 120 is a broadcast channel disposed in a bookstore, the advertisement may be advertisements related to books and records, and when the client computer 120 is disposed on a subway history, the advertisement may be advertisements related to travel and leisure. On the other hand, if the client computer 120 is a computer placed in a school or kindergarten as a paid member, it may provide only music content without inserting an advertisement file.
