Exemplary embodiments include a wireless transmitter and wireless receiver. The wireless transmitter and wireless receiver wirelessly transmit and receive data, respectively. The wireless transmitter and the wireless receiver each include a controller which outputs a power mode changing control signal to a power supply unit and a communication unit in response to a wakeup event, wherein the power supply unit changes a power mode from a standby mode to a normal mode in response to the power mode changing control signal. Both the wireless transmitter and receiver include a transmitter which transmits the power mode changing control signal to the other. With this configuration, there are provided an apparatus and a control method thereof which enable a wireless transmission of multimedia and consumes minimal power when in a standby mode.
