Manufacturers : TV and video : Satellite TV systems
Broadcasting television signals by satellite is a common method of providing television service. Communication satellites positioned in earth-synchronous orbits provide television signals to various countries around the world. Satellites receive television signals originating from earth and retransmit the signals back to earth. A satellite television broadcasting receiver is used for the purpose of receiving pictures and television broadcasting programs. Television receiver systems capture satellite transmissions, process the signals received, and select one for reception. The satellite broadcasting system is capable of transmitting a broadcast signal to much wider area than other broadcasting systems. Satellite television systems have emerged as an alternative to cable television systems. A digital satellite television system for direct television broadcasting includes a transmitter for transmitting television signals including video and audio components to a geostationary satellite. Satellite signals are in the GHz range in one of a number of bands, known as L, C, Ku and X bands. Earth station terminals typically downconvert signals to a range of about 0.95 to 2.2 GHz (L-band) by a low noise block converter forming part of most satellite signal receiving antennas. The satellite retransmits the received television signals to an outdoor antenna assembly that includes a dish-like antenna and a block converter. The dish-like antenna directs the received television signals to the block converter that converts the frequencies of the received television signals to respective lower frequencies. Direct broadcast satellite (DBS) systems allow households to receive television, audio, data and video directly from the DBS satellite. In the typical DBS system, the satellite receiver antenna includes an 18-inch parabolic dish, and the receiver unit is a television set-top decoder module.
