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