摘要
This demodulation device receives and demodulates a digital broadcast wave. This demodulation device includes an RF search control unit (41) and a GI search control unit (42). The RF search control unit (41) determines whether or not there is a broadcast wave in a certain channel, in accordance with an intensity of a signal outputted from a tuner (12) for receiving a digital broadcast wave. The GI search control unit (42) determines whether or not the broadcast wave is digital, based on whether or not the signal outputted from the tuner (12) contains a guard interval. Thus, the demodulation device is capable of efficiently searching for a channel containing a digital broadcast wave.
