Abstract
A receiver for VSB signals includes tuner channel changing circuitry. AGC circuitry, an IF FPLL and confidence counters, for indicating when signal acquisition or loss occurs. When a loss of signal indication is generated, the IF FPLL is reset, but not the tuner channel changing circuitry and the AGC circuitry, in order to quickly reacquire the signal. If the loss of signal indication persists for a predetermined time or for a predetermined number of loss of signal indications, the IF FPLL, the tuner channel changing circuitry and the AGC circuitry are all reset to reacquire the signal.
