Methods And Systems For Blending Between Analog And Digital Broadcast Signals

摘要

Systems and methods are disclosed that may be implemented to process a received RF spectrum that includes both analog modulated and digitally modulated RF signals to blend between a digital demodulated signal and an analog demodulated signal obtained from the received RF spectrum prior to performing one or more signal quality mitigation operations on the blended signal (e.g., such as stereo blend, hi-cut, etc.). In one embodiment, the digital demodulated signal and the analog demodulated signal may include at least some of the same information, e.g., such as information from simulcast digital and analog channels that are obtained from the same received RF spectrum.

1. A method for processing signals, comprising:
performing a digital/analog blending operation between a digital demodulated signal obtained from a digital modulated signal contained in a received radio frequency (RF) spectrum and an analog demodulated signal obtained from an analog modulated signal contained in the same received RF spectrum to produce a post-blend demodulated signal; and then performing one or more signal quality mitigation operations on the post-blend demodulated signal.
