Next, in order to display the generated upgrade overlay screen on the display device 300, control is performed to transmit the overlay screen to the display device 300 through the connection unit 420 (S420).

Hereinafter, a control method of a display apparatus and a control method of an upgrade apparatus of a display apparatus according to a third embodiment of the present invention will be described with reference to Figs. 12 and 13. Fig.

Referring to FIG. 12, in the control method of the display apparatus 500 according to the third embodiment, an upgrade apparatus upgraded to upgrade the display apparatus 500 is connected to the connection unit 520 (S500). Next, the upgrade apparatus 600 communicates with the upgrade apparatus 600 to encode the upgrade overlay screen data (S510). Next, the encoded overlay screen data is received and controlled to be decoded through the overlay decoder 560 (S520).

In addition, the control method of the display device 500 controls the overlay screen generated based on the decoded overlay screen data to be superimposed on the screen and displayed on the display unit.

Referring to FIG. 13, in the control method of the upgrade device 600 of the display device according to the third embodiment, the display device 500 is connected to the display device 500 through the connection part 620 (S610) (500), and controls the overlay encoder 630 to encode the upgrade overlay screen data (S620). Next, the encoded overlay screen data is transmitted to the display device 500 through the connection unit 620 (S630).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
