A control device which is arranged to control a broadcast receiver, comprising: a first communication interface unit which is arranged to selectively transmit a control command to the broadcast receiver in a first communication mode which uses a bi-directional wireless communication; a second communication interface unit which is arranged to selectively transmit the control command to the broadcast receiver in a second communication mode which uses a unidirectional wireless communication; a state determination unit which is arranged to determine the communication mode of the control device, the communication mode is determined to be the first communication mode when the control device can communicate via the first communication mode and, is determined to be the second communication mode when the control device cannot communicate via the first communication mode, wherein the state determination unit is arranged to determine that the first communication mode is not a communication-able state if the control device is in a sleep mode or a wake-up mode, the sleep mode is a state that the bi-directional wireless communication is stopped and the wake-up mode is a process of re-operating the stopped bi-directional wireless communication; a user interface unit which is arranged to display a user interface window which corresponds to the determined communication mode of the control device and to receive the control command for the broadcast receiver; a control unit which is arranged to control transmission of the received control command according to the determined communication mode to select transmission via the first or second communication interface unit (210, 220), and the user interface unit displays the user interface window corresponding to the second communication mode when the control device cannot communicate via the first communication mode. a first communication interface unit which is arranged to selectively transmit a control command to the broadcast receiver in a first communication mode which uses a bi-directional wireless communication; a second communication interface unit which is arranged to selectively transmit the control command to the broadcast receiver in a second communication mode which uses a unidirectional wireless communication; a state determination unit which is arranged to determine the communication mode of the control device, the communication mode is determined to be the first communication mode when the control device can communicate via the first communication mode and, is determined to be the second communication mode when the control device cannot communicate via the first communication mode, wherein the state determination unit is arranged to determine that the first communication mode is not a communication-able state if the control device is in a sleep mode or a wake-up mode, the sleep mode is a state that the bi-directional wireless communication is stopped and the wake-up mode is a process of re-operating the stopped bi-directional wireless communication; a user interface unit which is arranged to display a user interface window which corresponds to the determined communication mode of the control device and to receive the control command for the broadcast receiver; a control unit which is arranged to control transmission of the received control command according to the determined communication mode to select transmission via the first or second communication interface unit (210, 220), and the user interface unit displays the user interface window corresponding to the second communication mode when the control device cannot communicate via the first communication mode.
