Abstract:This paper takes the satellite receiving and transmission system construction of local high-end hotels as an example,uses satellite to receive overseas programs,demodulates and multiplexes self-run programs and radio and television cable programs,and transmits transcoding DTMB clear-flow radio frequency to the RF port of LCD TV which meets the new national standard for directdemodulation. It does not need to place set-top boxes in the room again to construct the simplest transmission system,which savesconstruction and maintenance costs.
