Satellite broadcast receiving and distribution system
DC CAFCFirst Claim
1. In a satellite television broadcast receiving system that receives differently-polarized satellite broadcast signals, said receiving system comprising a satellite dish antenna aimed to receive the differently-polarized satellite broadcast signals, and a head-in processor coupled to the satellite dish antenna, the head-in processor including a low-noise block converter and having an output for connection to a cable, said head-in processor supplying received satellite broadcast signals over the cable, said head-in processor including a converter configured to convert frequency-overlapping ones of the differently-polarized signals the satellite dish receives into non-interfering signals and in use apply said converted differently-polarized non-interfering signals simultaneously to the cable, the processor enabling two separate signals of different frequency and polarizations to travel simultaneously via said cable,satellite broadcast receiving equipment having a cable connection for in use being coupled to the cable, the satellite receiver equipment sending a command via the cable connection thereof to control selection of a polarization to be provided thereto over the cable so the satellite receiver can obtain, process and provide desired broadcast signals to a further device external to said satellite receiver.

Abstract
The present invention provides a satellite broadcast receiving and distribution system that will permit for the transmission of vertical and horizontal or left-hand circular and right-hand circular polarization signals simultaneously via a single coaxial cable. The system of the present invention will accommodate two different polarity commands from two or more different sources at the same time. This satellite broadcast receiving and distribution system of the present invention will provide for the signals received from the satellite to be converted to standard frequencies so as to permit for signals to travel via existing wiring which the present day amplifiers can transport in buildings, high-rises, hospitals, and the like so that satellite broadcasting can be viewed by numerous individuals by way of a single satellite antenna.
