Classification: H04N

Abstract:
A signal distribution circuit for a CATV converter for distributing CATV signals into signals for an analog/digital tuner, signals for a downstream tuner, and other signals, comprising:a directional coupler for distributing input CATV signals into signals that flow in a through direction and signals that flow in a branch direction; an extraction circuit for permitting, out of the signals output from the directional coupler in the through direction, only the signals for an analog/digital tuner and the downstream signals to pass therethrough; a gain control circuit for adjusting a gain of signals output from the extraction circuit; a first output terminal for connection to an analog/digital tuner for receiving CATV signals; a second output terminal for connection to a tuner for receiving downstream signals; a distributor for distributing the signals of which the gain has been adjusted by the gain control circuit to the first and second output terminals; and a circuit for processing the signals output from the directional coupler in the branch direction.
