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.

Claims

1. In a satellite television receiver adapted for connection to an associated television monitor, said receiver having means for an operator to select for display on its associated television monitor the programming broadcast by one of a plurality of transponders from one of a plurality of satellites, said satellite receiver having an associated remote control, said remote control having means for an operator to select for display the programming being broadcast by one of a plurality of transponders from one of a plurality of satellites, said satellite television receiver selection means including a programmable microprocessor, the improvement comprising means to program said microprocessor to thereby inhibit access to a selected transponder of a selected satellite, said programming means including said remote control in cooperation with the receiver operator selection means so that both said remote control and said receiver operator selection means are required to program said receiver.

2. The device of claim 1 further comprising means to de-program said microprocessor to thereby restore access to a previously inhibited transponder, said deprogramming means including said remote control in cooperation with the receiver operator selection means so that both said remote control and said receiver operator selection means are required to de-program said receiver.

3. The device of claim 2 wherein the programming means includes means to inhibit access to all of the transponders of a selected satellite as a group, and the de-programming means includes means to restore access to all of the transponders of a selected satellite as a group.

4. The device of claim 1 wherein the receiver further comprises means to communicate with others of said receivers, each receiver having means to be designated as a master or slave.

5. The device of claim 4 further comprising at least one other of said receivers connected to said receiver, one of said receivers being designated as a master and the other being designated as a slave, and wherein said master receiver has means to inhibit access by said slave receiver from those transponders and/or satellites programmed into said master receiver.

6. the device of claim 5 wherein said master receiver further comprises means to restore access by said slave receiver to those transponders and/or satellites de-programmed into said master receiver.

7. The device of claim 5 wherein said master receiver is connected to an antenna for receiving the programming broadcast by said satellites, said master receiver having means to control said antenna and communicate data concerning the positioning of said data to the slave receiver through said communication means.

8. The device of claim 7 wherein said slave receiver has means to control the antenna by communicating its commands through the communication means to the master receiver, the master receiver having means to receive and execute the slave receiver antenna commands.

9. The device of claim 6 wherein said slave receiver has means to inhibit access by said slave receiver only from those transponders and/or satellites programmed into said slave receiver.

10. The device of claim 9 wherein the slave receiver has means to restore access by said slave receiver only to those transponders and/or satellites de-programmed into said slave receiver.

11. A satellite television receiver adapted for connection to (1) an antenna for receiving programming broadcast by any one of a plurality of transponders transmitting from any one of a plurality of satellites, and (2) a television monitor for displaying the programming selected by said receiver, the receiver having means permitting operator selection of any one of said plurality of transponders for display, an associated remote control, said remote control permitting operator selection of any one of said plurality of transponders for display, said receiver transponder selection means including a programmable microprocessor, and means to program said microprocessor to inhibit operator selection of any one or more of said transponders, said programming means including the remote control coacting with the receiver transponder selection means to successfully enter a program inhibiting access to any one or more of said transponders.

12. The device of claim 11 further comprising a second one of said receivers, wherein each of said receivers has means to communicate with at least one other receiver, each of said receivers has means to be designated as a master or slave receiver, said receivers having means to adapt for direct communication to and control of the antenna when designated as a master and means to adapt for direct connection to the master when designated as a slave.

13. The device of claim 12 wherein said receivers have means to inhibit selection of a transponder by a slave in accordance with the programming entered in said master when designated as a master.

14. The device of claim 13 wherein said receivers have means to communicate present antenna positioning information over said communication means to other of said receivers connected thereto.
