Television-signal receiver and receiving method

A television-signal receiver comprising:

• a tuner receiving a television signal;
• a video demodulation unit for an analog broadcast received by the tuner;
• an audio demodulation unit for the analog broadcast received by the tuner;
• a data demodulation unit for a digital broadcast received by the tuner;
• a channel-selection controller that controls a channel received by the tuner and is capable of presetting the receive channel;
• and
• a determination unit that (i) determines whether a video signal demodulated in the video demodulation unit conforms to an NTSC standard, a PAL standard, or a SECAM standard, and utilizes the determined standard to analyze a blanking signal included in the video signal to obtain a blanking signal analysis result, and (ii) determines a country where the tuner receives the broadcasts based on a receive result by each channel-selection frequency in the tuner, the blanking signal analysis result, an analysis result of data demodulated in the data demodulation unit, and a demodulation result in the audio demodulation unit,
• wherein the controller sets a receive channel to be preset based on the result determined in the determination unit, and
• if a plurality of countries exist in a result as determined by the determination unit, the receive channel to be preset is selectable from the plurality of countries by an input operation performed by a user.
