Patent ID: 8265585

Claim:
A broadcasting receiver suitable for receiving a broadcasting signal transmitted in an IBOC signal format, comprising: a narrowband filtering unit that processes an analog broadcasting signal included in the broadcasting signal; a wideband filtering unit that processes a digital broadcasting signal included in the broadcasting signal; a demodulating unit that demodulates the broadcasting signal; a signal level detecting unit that detects a level of the broadcasting signal; a digital determining unit that determines whether the broadcasting signal includes the digital broadcasting signal or not; and a filter switching unit that switches a filtering unit for use in processing the broadcasting signal to be input to the demodulating unit between the narrowband filtering unit and the wideband filtering unit, according to the level of the detected broadcasting signal, when the digital determining unit determines that the broadcasting signal does not include the digital broadcasting signal; wherein the filter switching unit operates such that the broadcasting signal processed by the wideband filtering unit is input to the demodulating unit when the level of the detected broadcasting signal is higher than a certain value, and operates such that the broadcasting signal processed by the narrowband filtering unit is input to the demodulating unit when the level of the detected broadcasting signal is lower than or equal to the certain value.
