Patent ID: 7626636

Claim:
An electronic apparatus comprising: a receiver which receives a broadcast signal of a predetermined frequency band; a demodulator which filters the received broadcast signal using a filtering characteristic which is set in the demodulator, and separates the received broadcast signal into a video signal and an audio signal; a video decoder which executes a process for detecting frequencies of a vertical sync signal, a horizontal sync signal and a color sub-carrier signal which are included in the video signal which is output from the demodulator; a filtering characteristic control unit which refers to a result of the detecting process by the video decoder, while changing the filtering characteristic set in the demodulator among a plurality of kinds of filtering characteristics corresponding to a plurality of kinds of broadcast systems, thereby selecting, from the plurality of kinds of filtering characteristics, a filtering characteristic which enables the video decoder to detect the vertical sync signal, the horizontal sync signal and the color sub-carrier signal; and a broadcast standard determination unit which determines the kind of the broadcast standard corresponding to the received broadcast signal, based on the selected kind of filtering characteristic and the frequencies of the vertical sync signal, the horizontal sync signal and the color sub-carrier signal which are detected by the video decoder.
