摘要： Provided are an Internet protocol tuner that can classify Internet packets transmitted through the Internet into broadcasting packets and communication packets based on channel selecting information and extract transport stream from the broadcasting packets, and a method therefor. The Internet protocol tuner of the present research includes: a network interface unit for receiving an Internet packet; a packet classifying unit for classifying the Internet packets received; a transport stream extracting unit for extracting transport stream from the broadcasting packet; a transport stream transmitting unit for transmitting the transport stream; a transport stream receiving unit for receiving the transport stream from the decoding unit; a controller interface unit for receiving control information including channel selecting information from an external controller; and a tuning control unit for controlling the packet classifying unit, and controlling the transport stream extracting unit.

摘要： 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.
