To this end, the game client 12 provides a user interface through the game screen that allows the user to set whether to listen to a music broadcast of a specific channel as in the example described with reference to FIG. 4.

The game client 12 may be configured to play music content received from the streaming server 23 by connecting to a URL of a specific channel according to a user's setting.

In addition, the game client 12 may be linked with a separate computer program module (audio player) that accesses a URL of a specific channel and plays music content received from the streaming server 23.

In this case, the game client 12 may control the audio player to access a URL corresponding to a specific channel and receive and play a music broadcast from the streaming server 23 according to a user's setting.

On the other hand, even if the user wants to listen to music broadcasting, some of the various game sound effects may want to listen as it is.

Therefore, the user interface that allows the user to set whether or not to listen to the music broadcast of a specific channel may be configured to set whether to stop and stop when listening to music of the game sound effects, in this case, the game client (12) ) Does not stop game sound effects that the user has chosen to continue listening to.

The first storage 21, the channel management server 22, and the streaming server 23 are components for providing a real time music service through each channel.

As described above, the user may use the real time music service through the game client 12, but a user who does not use the game may use the real time music service.

That is, the user inputs a URL for directly accessing the channel to a web browser installed on the user terminal 11 or 14, or clicks a specific channel item on the wired / wireless homepage that provides channel information. You can listen to music broadcasts by accessing. In this case, even if the game client is not installed in the user terminal 14, the music broadcast can be listened to.

Now, the real-time music service provided by the online game service system will be described in detail.

In the context of the present invention, a channel refers to a path through which music data is transmitted in real time, such as a radio broadcast channel, and is divided into a Uniform Resource Locator (URL). Therefore, a plurality of channels may exist, and the type or number of music contents to be transmitted through each channel may be variously configured.

In addition, since the music service provided through each channel is performed in a streaming manner, a URL corresponding to each channel has a meaning of a connection path with the streaming server 23.

The first storage 21 is a non-volatile mass storage medium capable of reading and writing digital data.

A plurality of music contents may be stored in the first storage 21, and various information related to each music content such as a singer, a genre, and lyrics may be stored together as needed.

Since the music broadcasting of each channel is made based on the music contents stored in the first storage 21, the larger the number of music contents stored in the first storage 21, the more various music services can be provided. For example, hundreds of thousands of pieces of music content and related information may be stored in the first storage 21.

The channel management server 22 manages a list of contents corresponding to each channel.

The content list includes a predetermined number of music contents among the music contents stored in the first storage 21. The content list means a music selection table for each channel, and the content list of each channel may be changed.

The streaming server 23 transmits the music contents in the content list of the corresponding channel to the user terminal connected to each channel through the streaming method.

The computer program installed in the user terminals 11 and 14 and receiving and playing music data transmitted by the streaming server 23 in real time may be a game client 12 as described above, or may be a commercial computer program or specially manufactured. It may also be a distributed computer program.

6 is a diagram schematically illustrating a streaming service for each channel. The content list 17-1 for channel # 1 includes music contents # 4, # 11, # 26, # 58, and the like. The content list 17-2 for contains music contents # 126, # 129, # 30, # 108, and the like.

If a user terminal 11-1 accesses channel # 1, the streaming server 23 stores music in the content list 17-1 of channel # 1 among music contents stored in the first storage 21. The content is transmitted to the user terminal 11-1 in a streaming manner.

Also, if any user terminal 11-2 accesses channel # 2, the streaming server 23 is in the content list 17-2 of channel # 2 among the music contents stored in the first storage 21. The music content is transmitted to the user terminal 11-2 in a streaming manner.

Referring to FIG. 7, the streaming server 23 transmits the music content to the user terminal connected to each channel from the first music content in the content list of the corresponding channel to the current time point as if it were a radio broadcast.

That is, music contents in the content list are sequentially transmitted from the specific start time point to the end time point for each channel.

Therefore, user A starts listening to music data when t1 has elapsed since music content # 4 started to play, and user B began to listen after t2 after music content # 26 began to play. Start listening to music data from time.

When all the music content in the content list of a channel is transmitted, the process of starting to transmit from the first music content in the content list of the channel is repeated periodically.

Since the content list of each channel is subject to change, the content broadcast in each channel may be different for each cycle.

The period in which all the contents in the content list are transmitted and transmitted again from the beginning may have a certain time interval (eg, 12 hours).

If necessary, there may be a certain interval in which the broadcast is not performed until all the music contents in the contents list are transmitted and then the first music contents in the contents list of the corresponding channel starts to be transmitted again.

FIG. 8 illustrates an example in which a music service of a channel is repeated in a 12-hour cycle without a break, and the music contents in the content list of the channel are sequentially ordered from 0 o'clock to 12 o'clock on July 15, 2010. The music contents in the content list of the channel are sequentially broadcasted over 12 hours from 12 to 24 hours on July 15, 2010.

In this way, the real-time music service is repeatedly performed every 12 hours on the channel. When the content list changes in each cycle, the music that the user listens to in cycle # 1 and the music that is listened to in cycle # 2 are different.

FIG. 9 illustrates different embodiments related to channel operation, and may operate in a manner of determining a channel and a selection on the system side, such as radio broadcasting, or in a manner that allows users to open a channel and perform selection on their own. It can also be operated.
