Abstract
A cable television receiver includes in-band and out-of-band tuners integrated on a single IC. A mode controller determines whether an out-of-band signal is being received and powers the out-of-band tuner off when no out-of-band signal is present. A signal divider divides the signals between the in-band and out-of-band tuners and may be an asymmetric coupler in order to provide a higher power signal to the in-band tuner and a lower power signal to the out-of-band tuner.

12. A cable television receiver comprising:
-
an in-band tuner and an out-of-band tuner, wherein the in-band and out-of-band tuners are integrated on a single IC;
a mode controller for powering the out-of-band tuner on when an input RF signal on an out-of-band channel is received, and for powering the out-of-band tuner off when an input RF signal on an out-of-band channel is not received; and
a coupler that divides the input RF signal asymmetrically between the in-band tuner and the out-of-band tuner, providing a relatively higher power signal to the in-band tuner and a relatively lower power signal to the out-of-band tuner.

13. A method for tuning in-band and out-of-band cable channels on a single IC comprising:
-
receiving an input RF signal;
providing the input RF signal to an in-band tuner and to an out-of-band tuner;
detecting whether an input signal is on an out-of-band channel;
if the input signal is on an out-of-band channel, powering the out-of-band tuner on; and
if the input signal is not on an out-of-band channel, powering the out-of-band tuner off. - View Dependent Claims (14)

15. A cable television receiver comprising:
-
in-band tuning means for tuning RF signals received on in-band channels;
out-of-band tuning means for tuning RF signals received on out-of-band channels;
mode control means for powering the out-of-band tuning means on when RF signals on the out-of-band channels are received, and for powering the out-of-band tuning means off when RF signals on the out-of-band channels are not received; and
signal divider means for dividing the RF signals between the in-band tuning means and the out-of-band tuning means. - View Dependent Claims (16, 17, 18)

19. A method for tuning in-band and out-of-band cable frequency channels on a single IC comprising:
-
a step for receiving an input RF signal;
a step for dividing the input RF signal between an in-band tuner and an out-of-band tuner;
a step for powering the out-of-band tuner on if the input signal is on an out-of-band channel; and
a step for powering the out-of-band tuner off if the input signal is not on an out-of-band channel. - View Dependent Claims (20)
