The plurality of UIs includes a plurality of UI items for controlling the broadcast receiver, respectively. A control command is transmitted to the broadcast receiver in response to a user input selecting an UI item among the plurality of UI items for controlling the broadcast receiver. ## Claims ### Claim 1 A method for controlling a control device, the method comprising: receiving, from a broadcast receiver, first information regarding a content type of a content which is currently provided through the broadcast receiver; identifying a user interface (UI) corresponding to the content type of the content which is currently provided through the broadcast receiver among a plurality of UIs, based on the received first information, the plurality of UIs including different UI items for a plurality of content types, respectively; based on identifying that the content is a broadcast content, displaying a first UI including first UI items for changing a channel of the broadcast receiver and changing a volume of the broadcast receiver; based on identifying that the content is a game content, displaying a second UI including second UI items for four directional keys, respectively, for controlling the game content; and transmitting a control command to the broadcast receiver based on a user input selecting a UI item from among the first UI items and the second UI items for controlling the broadcast receiver and the content provided through the broadcast receiver. ### Claim 2 (depends on 1) The method of claim 1, further comprising: receiving, from the broadcast receiver, second information regarding a menu for a user selection of contents which can be provided through the broadcast receiver, and displaying the menu on the UI based on the second information. ### Claim 3 (depends on 2) The method of claim 2, further comprising: transmitting, to the broadcast receiver, third information indicating that the menu is displayed on the control device so that the broadcast receiver does not display the menu on a display of the broadcast receiver. ### Claim 4 (depends on 1) The method of claim 1, further comprising: identifying whether the control device is in a vertical mode or a horizontal mode based on an orientation sensed by a sensor of the control device, and displaying the UI based on the identifying that the control device is in the vertical mode. ### Claim 5 (depends on 4) The method of claim 4, further comprising: receiving the content from the broadcast receiver, and displaying the content based on the identifying that the control device is in the horizontal mode. ### Claim 6 (depends on 1) The method of claim 1, further comprising: based on the content being a DVD content, displaying the UI including UI items for playing, stopping, pausing, and recording the DVD content. ### Claim 7 (depends on 1) The method of claim 1, wherein the plurality of UIs are stored in a storage unit of the control device. ### Claim 8 A control device for controlling a broadcast receiver, the control device comprising: a display; a communication interface; and a control unit configured to: receive, via the communication interface, first information from the broadcast receiver regarding a content type of a content which is currently provided through the broadcast receiver, control the display to display a user interface (UI) corresponding to the content type of the content, which is currently provided through the broadcast receiver among a plurality of UIs, based on the received first information, the plurality of UIs including different UI items for a plurality of content types, respectively, and control the communication interface to transmit a control command to the broadcast receiver based on a user input selecting a UI item among the UI items displayed on the UI for controlling the broadcast receiver and the content provided through the broadcast receiver, wherein the control unit is further configured to: based on the content being a broadcast content, control the display to display the UI including the UI items comprising a UI item for changing a channel of the broadcast receiver and a UI item for changing a volume of the broadcast receiver, and based on the content being a game content, control the display to display the UI including the UI items for four directional keys, respectively, for controlling the game content. ### Claim 9 (depends on 8) The control device of claim 8, wherein the control unit is further configured to: receive, via the communication interface, second information from the broadcast receiver regarding a menu for a user selection of contents which can be provided through the broadcast receiver, and control the display to display the menu on the UI based on the second information. ### Claim 10 (depends on 9) The control device of claim 9, wherein the control unit is further configured to control the communication interface to transmit, to the broadcast receiver, third information indicating that the menu is displayed on the display of the control device so that the broadcast receiver does not display the menu on a display of the broadcast receiver. ### Claim 11 (depends on 8) The control device of claim 8, wherein the control device further comprises a sensor configured to sense an orientation of the control device being held by a user, and wherein the control unit further configured to: identify whether the control device is in a vertical mode or a horizontal mode based on the orientation sensed by the sensor, and control the display to display the UI based on the identifying that the control device is in the vertical mode. ### Claim 12 (depends on 11) The control device of claim 11, wherein the control unit is further configured to: receive, via the communication interface, the content from the broadcast receiver, and control the display to display the content based on the identifying that the control device is in the horizontal mode. ### Claim 13 (depends on 8) The control device of claim 8, wherein the control unit is further configured to, based on the content being a DVD content, control the display to display the UI including UI items for playing, stopping, pausing, and recording the DVD content. ### Claim 14 (depends on 8) The control device of claim 8, wherein the control device further comprises a storage unit, and wherein the plurality of UIs are stored in the storage unit. ### Claim 15 A non-transitory computer-readable medium having recorded thereon a program for executing a controlling method of a control device, the controlling method including: receiving, from a broadcast receiver, first information regarding a content type of a content which is currently provided through the broadcast receiver; identifying a user interface (UI) corresponding to the content type of the content, which is currently provided through the broadcast receiver among a plurality of UIs, based on the received first information, the plurality of UIs including different UI items for a plurality of content types, respectively; based on identifying that the content is a broadcast content, displaying a first UI including first UI items for changing a channel of the broadcast receiver and changing a volume of the broadcast receiver; based on identifying that the content is a game content, displaying a second UI including second UI items for four directional keys, respectively, for controlling the game content; and transmitting a control command to the broadcast receiver based on a user input selecting a UI item from among the first UI items and the second UI items for controlling the broadcast receiver and the content provided through the broadcast receiver. ### Claim 16 (depends on 15) The non-transitory computer-readable medium of claim 15, wherein the controlling method further comprises: receiving, from the broadcast receiver, second information regarding a menu for a user selection of contents which can be provided through the broadcast receiver, and displaying the menu on the UI based on the second information.
