Meanwhile, the server 200 may transmit content to the display apparatus 100 ( S603 ) and transmit lookup table information ( S621 ). Here, the content may refer generically to transmitting information using at least one of text, an image, or an image, and in particular, the content may mean an advertisement. In addition, the display apparatus 100 may predict the loading time for each of the plurality of services by using the lookup table received from the server 200 .

Then, the display apparatus 100 requests the first service to the external server 400 (S622), and the external server 400 transmits the URL to the display apparatus 100 requesting the first service (S623) to the display apparatus (100) can be made accessible to the external server (400). Here, the URL may be an address allocated to use an information resource in the network.

Alternatively, since the first service is provided using an application and the first service may be loaded using an instruction included in the application, the display apparatus 100 requests the first service and transmits a URL in response thereto. A series of steps may be omitted.

The display apparatus 100 may load the first service using the transmitted URL and display the content during the loading time (S630). Specifically, the display apparatus 100 may predict the loading time for the first service by using the lookup table received from the server 200 . In addition, the display apparatus 100 may output content during the predicted loading time.

Also, the display apparatus 100 may measure a loading time at which the first service is loaded. Then, the display apparatus 100 may transmit the measured loading time information to the server 200 (S631).

Then, the display apparatus 100 may load the second service ( S640 ) and measure a loading time at which the second service is loaded. Then, the display apparatus 100 may transmit the measured loading time information to the server and request the server 200 for a second service and content corresponding to the loading time of the second service ( S641 ).

In addition, the server 200 may transmit the content related to the second service requested from the display apparatus 100 to the display apparatus 100 ( S642 ), and a lookup table pre-created using the loading time information of the second service can be updated (S650). The updated lookup table may be transmitted to the display apparatus 100 by the server 200 (S651), and the display apparatus 100 uses the updated lookup table information to provide more accurate information about the first service and the second service. The loading time is predictable.
