Abstract
An apparatus for reducing power consumption in a digital broadcast receiver is provided. An AC-to-DC converter converts input AC power into DC power that can be used in the receiver. A power control switch selectively supplies the DC power from the converter to a tuner unit and a decoder according to a command of a controller. The tuner unit receives broadcast channel signals and demodulates the received broadcast channel signals according to the respective broadcast formats. The decoder receives the demodulated broadcast signals from the tuner unit and decodes analog/digital broadcast signals. A multimedia output port is connected between the decoder and the display unit to transfer the audio/video output signals from the decoder to the display unit. The controller detects the state of the display unit through the multimedia output port to control whether to supply the DC power through the power control switch.
