Title:
受信機及び受信方法
Document Type and Number:
Japanese Patent JP4147744
Kind Code:
B2
Abstract:
The present invention relates to a receiver and a receiving method, both for use in a broadcasting system in which analog broadcast signals and digital broadcast signals are transmitted in adjacent frequency bands. The receiver has an analog processing circuit for receiving and processing analog broadcast-wave signals to extract audio signals; a digital signal processing circuit for receiving and processing digital broadcast-wave signals to extract audio signals; a changeover circuit for selecting either the audio signals supplied from the analog processing circuit or the audio signals supplied from the digital signal processing circuit; a control circuit for controlling the application of an operating power-supply voltage to the digital processing circuit; and detecting means for detecting that a digital broadcast station has been selected. The control circuit applies the operating power-supply voltage to the digital processing circuit only when the detecting means detects that a digital broadcast station has been selected. Thus, it is possible to reduce the power consumption.
