An embodiment of a data transmission method according to the present invention will be described with reference to FIGS. 1A to 5 as follows.

First, in step S10, the content supply server 20 forms the content information including a plurality of selected content data and information data related to the content data in a package (S10). In the present embodiment, a description will be given taking an example of using the ten pieces of content data most viewed through the Internet as content information.

The content application server 50 receives the packaged content information from the content supply server 20. Then, the process of converting the content information is performed (S12).

The content application server 50 analyzes the content information received in step S121. At this time, the content application server 50 analyzes the content data using the information data included in the content information. The content application server 50 may confirm that the content data currently received through the information data is the top 10 UGC data most frequently inquired through the Internet.

Then, in step S122, the content application server 50 adds information about the content data to the ESG. In this process, the content application server 50 may add information on the content data to a conventional ESG reserved field.

However, the present embodiment uses a method of adding a new fragment to the ESG. That is, the ESG according to the present embodiment is a conventional fragment (eg, service fragment, schedule event fragment, content fragment, acquisition fragment, service bundle fragment, purchase ( In addition to the Purchase) fragment, the purchase channel fragment further includes a data transmission fragment including information of content data. The data transmission fragment according to the present embodiment includes all information on content data transmitted through the FLUTE protocol, and may be referred to by other fragments.

Accordingly, the content application server 50 according to the present embodiment adds all information related to the corresponding content data to the data transmission fragment based on the information data.

When the ESG is generated by adding the content data information to the data transmission fragment of the ESG, the content application server 50 generates the popup display information in step S123.

The pop-up display information according to the present embodiment is information indicating a user interface of a pop-up displayed on the mobile communication terminal 100 when content data is received by the mobile communication terminal 100. That is, it shows the GUI scheme of the pop-up message applied to the transmitted content data. Such popup display information may be arbitrarily set in the content application server 50. In this process, the content application server 50 generates pop-up display information based on broadcast technology information to correspond to the characteristics of the selected content data. For example, when the content data are children, the content application server 50 may generate popup display information so that the popup is displayed with a bright and cute feeling.

Next, the content application server 50 performs a DRM setting process of the content data in step S124. The content application server 50 checks whether copyright is set in the content data included in the content information based on the broadcast description information. If the content data can be used without any restrictions in relation to copyright, etc., the content application server 50 proceeds to the next step S125.

However, if copyright is set for the content data or if the DRM is requested to be applied, the content applying server 50 communicates with the authentication server 30 and applies the DRM to the corresponding content data.

Next, an S125 process of converting content data into a format suitable for viewing by the mobile communication terminal 100 is performed. The content application server 50 checks the format and resolution of the content data. In general, the content data transmitted from the content supply server 20 has a format and resolution that is easy to use in a personal computer (PC). Therefore, content data of this format and resolution may be difficult to use in the mobile communication terminal 100. Accordingly, the content application server 50 according to the present embodiment converts the content data transmitted from the content supply server 20 into a universal format that can be easily viewed by all mobile communication terminals 100. In the case of content data including video, the screen size and resolution are adjusted to be suitable for the display unit 150 of the mobile communication terminal 100. In this process, the content application server 50 may use tans-coder.

When the conversion of the content data is completed through this process, the content application server 50 transmits the generated ESG and the converted content data to the broadcast network server 40 in step S13.

In step S14, the broadcasting network server 40 transmits the data transmission channel, that is, the ESG received through the FLUTE protocol and the converted content data to the broadcasting network 90.

When the broadcast signal including the content data is transmitted from the data transmitting terminal 70 to the broadcasting network 90 as described above, the process of receiving the same from the mobile communication terminal 100 which is the data receiving terminal 100 is performed.

In the data receiving process of the mobile communication terminal 100 according to the embodiment of the present invention, power is first applied to the mobile communication terminal 100, and the standby state in which the display unit 150 displays a standby screen according to a normal operation is performed. A process of entering S20 is performed.

Subsequently, an S21 process in which an ESG confirmation request is received by the mobile communication terminal 100 is performed. In the present embodiment, the ESG confirmation request is periodically generated by the ESG processing unit 192 of the broadcast receiving module 196. That is, the ESG processor 192 according to the present invention repeatedly generates an ESG confirmation request by itself at regular intervals (for example, 1 hour). Here, the period for generating the ESG confirmation request may be specified by the user.

Meanwhile, the ESG confirmation request according to the present invention may use a method input through a mobile communication network. That is, after the content transmitter 70 transmits the content data through the broadcast network 90 (S14), the content supply server 20 transmits the updated information (eg, the current broadcast network 90) through the service provider 40. Information indicating that new content data is new) may be transmitted to the mobile communication terminal 100.

In this case, the pop-up module 198 of the mobile communication terminal 100 transmits an ESG confirmation request signal to the ESG processing unit 192 of the broadcast receiving module 196.

When the ESG confirmation request is received by the ESG processor 192 through such cases, the ESG processor 192 drives the digital broadcast receiver 120 to obtain a digital broadcast signal in step S22. The ESG received through the data transmission channel is extracted from the acquired digital broadcast signal.

Subsequently, in step S24, the ESG processing unit 192 compares the existing ESG already stored in the storage unit 170 of the mobile communication terminal 100 with the ESG recently received and extracted. At this time, the ESG processing unit 192 extracts the information stored in the data transmission fragment of the ESG. Then, the extracted information is used to compare whether there is other new content data with previously transmitted content data.

 As a result of the comparison, when the existing ESG and the recent ESG are the same, the ESG processing unit 192 recognizes that the content data currently transmitted through the digital broadcast signal is the same as before.

In response, the ESG processor 192 stops driving the digital broadcast receiver 120 in step S241 and enters step S242 to wait for a predetermined time (for example, one hour). After a certain time, the ESG processing unit 192 again enters the process S21 and repeatedly performs the processes S21 to S24 described above.

On the other hand, if the existing ESG and the current ESG is different in the step S24, that is, if the information on the new content data is stored in the content of the data transmission fragment, ESG processing unit 192 to the content acquisition unit 194 Inform.

In step S25, the content acquirer 194 stores all data transmitted through the FLUTE protocol of the data transmission channel among the digital broadcast signals received through the digital broadcast receiver 120 and extracts content data therefrom. .

When the content data is extracted, the content acquisition unit 194 stores the content data extracted in step S26 in the storage unit 170. At the same time, the content acquisition unit 194 informs the pop-up module 198 that new content data has been stored.

The pop-up module 198 displays a pop-up window (or pop-up message) on the display unit 150 of the mobile communication terminal 100 in step S27. In this case, the pop-up window according to the present embodiment may be displayed as a GUI based on the pop-up display information set by the content application server 50 in step S123 described above. In addition, it is preferable that the pop-up window is displayed with the content that the new content data has been received together with a play button for immediately playing the content data. Although not shown, when the play button is input, the pop-up module 196 may notify the broadcast receiving module 196 to play a corresponding content data.

Through this process, the content data stored in the storage unit 170 is displayed on the display unit 150 in response to a reproduction request of the user of the mobile communication terminal 100. On the other hand, in the case of content data to which the DRM is applied, the mobile communication terminal 100 may view after obtaining a use right through communication with the authentication server 30.
