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, wherein the second communication interface unit operates at a lower power than the first communication interface unit; and a control unit which is arranged to transmit the control command to the broadcast receiver through the first or the second communication interface unit (210, 220) according to communication mode, which is one out of the first communication mode or the second communication mode; the device further comprising: a state determination unit which is arranged to determine the communication mode of the control device; 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 and wherein the communication mode is determined to be the second communication mode when the control device cannot communicate via the first communication mode; wherein 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; and 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; wherein the control unit is arranged to transmit the control command to the broadcast receiver through the second communication interface unit (210, 220) if the communication mode is determined to be the second 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, wherein the second communication interface unit operates at a lower power than the first communication interface unit; and a control unit which is arranged to transmit the control command to the broadcast receiver through the first or the second communication interface unit (210, 220) according to communication mode, which is one out of the first communication mode or the second communication mode; the device further comprising: a state determination unit which is arranged to determine the communication mode of the control device; 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 and wherein the communication mode is determined to be the second communication mode when the control device cannot communicate via the first communication mode; wherein 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; and 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 state determination unit which is arranged to determine the communication mode of the control device; 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 and wherein the communication mode is determined to be the second communication mode when the control device cannot communicate via the first communication mode; wherein 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; and 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; wherein the control unit is arranged to transmit the control command to the broadcast receiver through the second communication interface unit (210, 220) if the communication mode is determined to be the second communication mode.
