If at least one of the one or more applications is selected from the history, the processor outputs an execution screen of the selected application on the display according to the corresponding layout.

Abstract: Disclosed is a cooling system for a conversion device that includes a heat sinking plane, a main cooling jacket, and a sub-cooling jacket. The main cooling jacket is connected with the heat sinking plane and provided with a first component disposed thereto. The sub cooling jacket is connected with the heat sinking plane on the opposite side of the main cooling jacket, and provided with a second component which generates a relatively lower amount of heat than the first component. A main inlet is disposed in the main cooling jacket for supplying coolant to the main cooling jacket, and an outlet is disposed in the sub cooling jacket for exhausting the coolant which has passed through the sub cooling jacket. A sub inlet is formed in the heat sinking plane for the coolant passing through the main cooling jacket to be supplied to the sub cooling jacket.

Abstract: A method for providing Graphical User Interface (GUI) for selecting a broadcast channel, and a broadcast receiving apparatus having the same are provided. The GUI for selecting a broadcast channel includes a keypad having a pointer to be moved by manipulation of a user on a remote control apparatus and keys selectable by the pointer, and then the user is able to input a preferred broadcast channel by using the keypad and the pointer. Accordingly, the user is able to input a preferred broadcast channel without using the number keys, so the number keys may be omitted in the remote control apparatus. As a result, miniaturization of the remote control apparatus is possible.
