摘要： The present invention concerns a method and associated apparatus for setting automatic gain control (AGC) parameters based upon power approximations from both within and outside of the channel of interest. A frequency range is scanned in narrow slices to determine approximate input power within each slice. Automatic gain control and other parameters are then adjusted based upon aggregate power values. The algorithm may be implemented in software, using existing AGC circuitry to provide input power measurements, thereby reducing system complexity and the need for additional detection circuitry.

摘要： A set top box is described including multiple tuners and an apparatus (100) and method (800) for controlling signal level. The apparatus (100) includes a signal splitter (102) for splitting signal power of a signal between an input and at least two outputs, a controller (116) coupled to an output, and a circuit (310, 410) controlled by the controller (116) and selectively coupled to the signal splitter (102) for altering a signal transfer response characteristic of the signal. The method (800) describes controlling the signal level of signals outputted by a signal splitter including determining (808) a signal quality characteristic of one of the output signals and altering (814) a signal response in the signal splitter in response to comparing (810) the signal quality characteristic to a predetermined signal quality characteristic threshold.
