Abstract
A satellite television reception only receiver includes a programmable microprocessor which has a communications link for communicating between a plurality of receivers connected in a multiple receiver installation. An antenna is connected to only one receiver in the network, and it controls operation of the antenna, and the information relating to the antenna is transmitted to the other receivers to update them. The microprocessor further provides a means to programmably restrict access to particular satellites or transponders on satellites at each individual receiver, and vary the particular transponders or satellites restricted from receiver to receiver.
