SATELLITE BROADCAST DISTRIBUTION SYSTEM

摘要

PURPOSE: A satellite broadcast distribution system is provided to serve a satellite broadcast to a number of households by using only one antenna. CONSTITUTION: A satellite broadcast distribution system distributes a satellite signal of ultrahigh frequency received through one satellite antenna to a number of satellite broadcast receivers. The system comprises: a first low noise converter(110) converting a right polarization of the satellite signal to an intermediate frequency within the established frequency band; a second low noise converter(120) converting a left polarization of the satellite signal to an intermediate frequency; and a frequency synthesizing part(130) outputting an intermediate frequency, which includes the intermediate frequency band of the right polarization and the intermediate frequency of the left polarization by synthesizing the intermediate frequencies converted in each of the first and second low noise converter, to each of a number of satellite broadcast receivers(200).
