Electronic Device and Control Method Thereof

An electronic device and a control method thereof includes an infrared module which receives an infrared control signal having a predetermined section-specific waveform from an infrared transmitter, a switching unit which turns on/off the infrared module, and a controller which controls the switching unit to alternately turn on and off the infrared module in a predetermined cycle for recognizing the predetermined section-specific waveform of the infrared control signal. Thus, electric power consumed by an infrared module in a standby mode may be reduced while receiving a signal of an infrared transmitter.
