Patent ID: 8005435

Claim:
A method for processing one or more information signals comprising: receiving a broadcast radio frequency (RF) signal, said broadcast RF signal representing one of said one or more information signals; translating said broadcast RF signal to a low-frequency intermediate frequency (IF) signal using a reference signal provided by a phase-locked loop (PLL), said PLL configured to selectively provide said reference signal at one of a plurality of frequencies, wherein each said plurality of frequencies represent a center frequency for a plurality of signal band groups; selectively modulating said low-frequency IF signal into a baseband information signal, wherein said selectively modulating said low-frequency IF signal comprises selecting one of modulating said low-frequency IF signal and not modulating said low-frequency IF signal; digitizing said baseband information signal into a digital information signal; designating another digital information signal for transmission; converting said another digital information signal into an analog baseband signal; selectively converting said analog baseband signal into another low-frequency IF signal, wherein said selectively converting said analog baseband signal comprises selecting one of converting said analog baseband signal and not converting said analog baseband signal; selectively modulating said another low-frequency IF signal into a transmission RF signal using a transmission reference signal provided by said PLL; and transmitting said transmission RF signal.
