The terminal 130 converts the information included in the parsing data into a database and stores the information in the terminal 130 (S530). On the other hand, when receiving the new parsing data from the terminal relay device 120, the terminal 130 determines whether the new parsing data matches the pre-stored information. At this time, when it is determined that the new parsing data includes information different from the information that is already stored in the terminal 130, the terminal 130 stores the information that is already stored in the database 130 based on the information included in the new parsing data . Accordingly, when the user uses the IPTV service using the terminal 130, the user can continuously check the real-time channel information.

When the terminal 130 receives an input signal from the user, the terminal 130 extracts information corresponding to the input signal from the database information, and displays the extracted information on the terminal 130 (S540). That is, when the terminal 130 receives the input signal for the real-time channel information from the user, the terminal 130 applies the information corresponding to the input signal to the previously set UI.

5, it is described that steps S500 to S540 are sequentially executed. However, this is merely illustrative of the technical idea of an embodiment of the present invention, and it is to be understood that the present invention is not limited to the above- Those skilled in the art will understand that various changes and modifications may be made to those skilled in the art without departing from the essential characteristics of one embodiment of the present invention or by executing one or more of steps S500 through S540 in parallel 5, it is not limited to the time-series order.
