Abstract:
A television receiving apparatus for receiving an analog television broadcast and a digital television broadcast, comprising:tuner means for receiving both an analog television broadcast signal and a digital television broadcast signal, selecting a signal having a desired carrier frequency from the received signals, and converting the selected signal having the desired carrier frequency into an intermediate frequency signal; analog demodulating means for demodulating the analog television broadcast signal to a video signal; digital demodulating means for demodulating the digital television broadcast signal to a base band signal; first filter means disposed downstream of said tuner means; second filter means disposed between said first filter means and said analog demodulating means; third filter means disposed between said first filter means and said digital demodulating means; and switch means for selectively outputting an AFT control signal for the analog television broadcast and an AFT control signal for the digital television broadcast, the AFT control signal for the analog television broadcast being output from said analog demodulating means, the AFT control signal for the digital television broadcast being output from said digital demodulating means, wherein the reception frequency of said tuner means is set corresponding to the AFT control signal for the analog television broadcast when the analog television broadcast is received, the reception frequency of said tuner means is set corresponding to the AFT control signal for the digital television broadcast when the digital television broadcast is received, and wherein the AFT control signals enable said first filter means to flexibly operate with both the analog television broadcast signal and the digital television broadcast signal.
