A digital broadcast recorder capable of recording digital television (TV) signals
includes a first frequency converter which converts a received digitally modulated
TV signal into a first intermediate frequency signal having a frequency lower than
that of the digitally modulated TV signal, the first intermediate frequency signal
having a frequency in a standard TV band and useable in demodulating standard TV
signals, a band-pass filter coupled to the first frequency converter, which selectively
passes-through the first intermediate frequency signal, a phase-lock loop (PLL)
circuit coupled to the first frequency converter, which controls an oscillation
frequency of a local oscillator in the first frequency converter, a second frequency
converter coupled to the band-pass filter, which converts the first intermediate
frequency signal passed through the band-pass filter into a second intermediate
frequency signal lower in frequency than said first intermediate frequency signal
a digital demodulator coupled to the second frequency converter, which demodulates
the second intermediate frequency signal as converted by the second frequency converter
and a writer coupled to the digital demodulator, which records demodulated signal
as demodulated by said digital demodulator in a recording medium.
