In one embodiment of the present invention, the content providing server 100 is a user terminal corresponding to the requested content in response to the content providing request of the user terminals (310 to 330) received from the node server 200, and requested to provide the content, For example, the content data having a format suitable for the first user terminal 310 is transmitted to the first user terminal 310 through the node server 200.

The content providing server 100 may collect content providing requests received from the user terminals 310 to 330, and generate preference information for one or more contents based on the collected content providing requests.

The content providing server 100 may transmit content data of one or more formats of content initially requested from the node server 200 to the node server 200.

The content providing server 100 may transmit and store content data of content corresponding to a preference of a predetermined threshold or more to the node server 200 in advance by using the generated preference information.

Accordingly, the node server 200 may store content data of various formats for one content in advance.

The node server 200 receives a content providing request from one of the one or more user terminals 310 to 330 connected to the node server 200, for example, the first user terminal 310, and receives the first user terminal. It is determined whether or not the content data corresponding to the requested content 310 is stored in the format suitable for the first user terminal 310.

When the node server 200 stores content data of a suitable format corresponding to the content requested by the first user terminal 310, the node server 200 transmits the corresponding content data to the first user terminal 310.

When the node server 200 does not store the appropriate content data corresponding to the content requested by the first user terminal 310, the node server 200 requests the content data from the content providing server 100 or another data stored in the node server 200. The content data of the format may be transcoded and provided to the first user terminal 310.

When the content requested by the first user terminal 310 is the first content to be provided to the content providing server 100 through the node server 200, the node server 200 receives the first user terminal 310 of the requested content. In addition to the content data of the format suitable for the second user terminal 320 and the content data of the format suitable for the third user terminal 330 can be received in advance and stored.

In addition, the node server 200 may receive content data having a preference value or more from the content providing server 100. In this case, the node server 200 may receive and store content data having a format suitable for the second user terminal 320 and the third user terminal 330 as well as the first user terminal 310.

When the node server 200 does not have at least one piece of content data among the pieces of content data suitable for each of the first user terminal 310 to the third user terminal 330 among the content data received from the content providing server 100. By using the received content data, content data that does not exist may be directly transcoded and generated.

For example, the node server 200 receives content data suitable for the first user terminal 310 and the second user terminal 320 from the content providing server 100 and content data suitable for the third user terminal 330. If not received, the node server 200 transcodes the content data suitable for the first user terminal 310 or the second user terminal 320 to obtain content data suitable for the third user terminal 330. Can be generated.

One or more user terminals 310 to 330 request content from the content providing server 100 through the node server 200. The user terminals 310 to 330 may receive content data corresponding to the content requested from the content providing server 100 through the node server 200, and reproduce the content using the received content data.

In step S115, the content providing server 100 provides the node server 200 with content data of a format corresponding to the content requested for providing in step S110 and suitable for the user terminal 300. The user terminal can reproduce the content by using the content data of a format suitable for the user terminal.

In step S120, the node server 200 transmits the content data received from the content providing server 100 to the user terminal 300 in step S115.

In step S125, the user terminal 300 plays the content requested in step S105 by using the content data received in step S120.

In step S130, the node server 200 requests the content providing server 100 for one or more content data of another format corresponding to the content data provided in step S120.

In operation S125, the node server 200 provides content data having a format suitable for the user terminal 300 to the user terminal 300, and in operation S130, the node server 200 may be configured for the other user terminal. The content data may be requested to the content providing server 100 again.

In step S135, the content providing server 100 transmits the content data of one or more other formats requested in step S130 to the node server 200. The content providing server 100 may include content data of one or more formats corresponding to one content.

For example, the content providing server 100 may include first content data in a format that can be played through IPTV and second content data in a format that can be played through a smartphone, for the A movie content.

Therefore, the content providing server 100 may provide the node server 200 with one or more content data corresponding to a format other than the format of the content data provided in step S115.

In step S140, the node server 200 stores one or more pieces of content data received in step S135.

In step S145, the content providing server 100 collects a content usage record based on the provision of the content data in step S115. The content providing server 100 may collect information of content provided to the plurality of user terminals by the content providing server 100.

In step S150, the content providing server 100 calculates a preference of one or more pieces of content provided by the content providing server 100 based on the content usage record collected in step S145 to generate preference information for the content. do.

The preference information generated by the content providing server 100 may include preference ranking information, content information of a corresponding ranking, type information of a user terminal provided with content, information on the number of provisions, and the like.

In step S155, the content providing server 100 transmits the content data corresponding to the high content content to the node server 200 based on the preference information generated in step S150.

The content providing server 100 selects content having a preference rank or a preference score equal to or greater than a preset threshold, and transmits content data of one or more formats of the selected content stored in the content providing server 100 to the node server 200. Can be provided.

The content providing server 100 may transmit the content data of one or more formats of the selected content to the node server 200 when the network usage between the content providing server 100 and the node server 200 is equal to or less than a preset threshold. have. For example, the content providing server 100 may store content data of one or more formats of the content selected during the time when the network between the content providing server 100 and the node server 200 is least used, and in general, the minimum time. 200).

In step S160, the node server 200 stores the content data received in step S155 in a database.

In step S165, the node server 200 analyzes the content data received and stored in step S160, whether all of the content data of a format suitable for one or more user terminals connected to the node server 200 are included. Judge.

For example, when the node server 200 is connected to user equipment of type A, type B, and type C, the node server 200 checks that the content data of one or more formats received and stored in step S160 is type A, type B. It is determined whether a format suitable for both type and C type user terminals is included.

If the node server does not include at least one of the content data of a format suitable for one or more user terminals connected to the node server 200 when the content data of one or more formats stored in step S160 is used, the node server uses the content data of the stored format. Generates content data of the format.

That is, when the content data of one or more formats stored in step S160 does not include content data of a format suitable for some type of user terminal, for example, the content data of one or more formats stored in step S160 is A. In the case of including the content data of a format suitable for a type and a B type user terminal, but not including the content data of a format suitable for a C type user terminal, the node server 200 is a format suitable for a type A or B type user terminal. The content data of the C-type may be generated by transcoding the content data.

In an embodiment of the present invention, it has been described that the node server 200 transcodes the content data of a format suitable for at least one user terminal connected to the node server 200 immediately after receiving the content data in step S155. The node server 200 is not limited thereto, and the node server 200 uses the content data received when the resource usage of the node server 200, that is, an idle state in which processing capacity is equal to or less than a preset threshold value, is used. The content data of the format suitable for the user terminal connected to the 200 may be transcoded.

In operation S170, the user terminal 300 requests the node server 200 to provide specific content.

In step S175, the node server 200 stores content data of one or more formats of the content requested in step S170 in the node server 200, and a format suitable for the user terminal 300 among the stored content data. If there is content data of the node, the node server 200 transmits and provides the corresponding content data to the user terminal (300).

In step S180, the user terminal 300 plays the content requested in step S170 by using the content data received in step S175.

In an embodiment of the present invention, the content data has been described as being provided from the content providing server to the node server, but is not limited thereto. The node server may receive content data from another node server connected thereto, and transcode the received content data. It is also possible to generate content data in other formats.
