• a display;
• an interface unit configured to wirelessly receive a user's input from a remote controller;
• a wireless communication unit configured to wirelessly communicate with the transmitting device;
• and
• a controller configured to:
• receive a first input for displaying an external input list, and
• display an external input list in response to the first input,
• wherein the external input list includes:
• a first button for displaying a first external input list including at least one icon corresponding to at least one external device connected to the transmitting device;
• and
• a second button for displaying a second external input list including at least one icon representing at least one external device connected to the display device,
• wherein the first external input list is displayed when the first button is selected, and
• wherein the second external input list is displayed when the second button is selected,
• receive, by the display device, a second input for selecting an icon from the external input list, and
• access, by the display device, an external input corresponding to the selected icon in response to the second input.

A method for controlling, by a display device, operations of at least one external input of a transmitting device connected to the display device, the method comprising:

• receiving, by the display device, a first input for displaying an external input list;
• displaying, by the display device, the external input list in response to the first input,
• wherein the external input list includes:
• a first external input list including at least one icon corresponding to at least one external device connected to the transmitting device, and
• a second external input list including at least one icon representing at least one external device connected to the display device, and
• wherein the first external input list is displayed in a first region and the second external input list is displayed in a second region;
• receiving, by the display device, a second input for selecting an icon from the external input list;
• and
• accessing, by the display device, to an external input corresponding to the selected icon in response to the second input.
