Patent ID: 7952648

Claim:
A broadcast receiving module comprising: a controller; a receiver for selecting a signal of a specific channel from signals of a plurality of channels from a common broadcast under control of the controller; a demodulator connected to an output of the receiver; a detector for detecting a signal-to-noise ratio of the signal selected by the receiver; and a comparator for comparing the signal-to-noise ratio detected by the detector with a predetermined level, wherein in a case where the receiver has selected a signal of a first channel, when a comparison result of the comparator indicates that the signal-to-noise ratio of the signal of the first channel is below the predetermined level, the controller controls the receiver to replace the signal of the first channel with a signal of a second channel from the common broadcast, and when the comparison result of the comparator indicates that the signal-to-noise ratio of the signal of the first channel is not less than the predetermined level, the controller controls the demodulator to demodulate the signal of the first channel.
