ABSTRACT:
A method and apparatus within a television receiver for electronically aligning signals within the receiver by controlling support circuitry for an IF module. A control voltage source controls both video alignment and picture IF (PIF) mute functions. The DAC is coupled to a video level control circuit within the video amplifier circuitry of the television receiver. The control signal controls both the video level as well as a PIF mute circuit.
