PURPOSE: A method and a system for receiving new digital satellite broadcasting are provided to share a tuner, a DEMUX and/or a demodulator/ADC by a community dwelling house unit. CONSTITUTION: A transmitted RF signal(1) is transmitted to a parabola antenna(4) installed to the interior of a room via a broadcasting satellite and down shifted with L-bandwidth by an LNB(5). The L-bandwidth signal is transmitted to a tuner(7) via a coaxial cable(6). The signal transmitted to the tuner(7) is separated into signals of all channels and outputted by a fixing channel filtering unit. The separated channel signals(2a to 2n) are converted into digital signals by ADCs(8a to 8n) and thereafter transmitted to a network processor(9). Thereafter, the intrinsic identification information are given to the signals and then transmitted to a backbone network(11) via a switching hub(10). The signals transmitted to the backbone network(11) are transmitted to a display device via settop boxes(12a to 12m) by user's request.
