Abstract

A subscriber electronic media distribution system including a broadcast transmission reception system and an authentication system. The broadcast transmission reception system includes a receiver. The authentication system is provided for allowing the receiver to descramble a scrambled broadcast transmission received by the receiver. The authentication system includes an authentication server and a receiver geographic position locating system for determining a geographic position of the receiver. When the receiver is determined to be in a predetermined geographic position, the authentication system is adapted to send an authentication signal to the receiver for descrambling the scrambled broadcast transmission.

Claims

1. A subscriber electronic media distribution system comprising:

a broadcast transmission reception system comprising a receiver; and

an authentication system for allowing the receiver to descramble a scrambled broadcast transmission received by the receiver, the authentication system comprising an authentication server and a receiver geographic position locating system for determining a geographic position of the receiver,

wherein, when the receiver is determined to be in a predetermined geographic position, the authentication system is adapted to send an authentication signal to the receiver for descrambling the scrambled broadcast transmission.

2. A subscriber electronic media distribution system as in claim 1 wherein the broadcast transmission reception system further comprises a satellite antenna coupled to the receiver.

3. A subscriber electronic media distribution system as in claim 2 wherein the receiver comprises a satellite signal descrambler.

4. A subscriber electronic media distribution system as in claim 1 wherein the receiver geographic position locating system comprises a radio frequency transceiver.

5. A subscriber electronic media distribution system as in claim 4 wherein the receiver geographic position locating system comprises an Assisted Global Positioning System (AGPS).

6. A subscriber electronic media distribution system as in claim 4 wherein the receiver geographic position locating system comprises an Enhanced Observed Time Difference (EOTD) system.

7. A subscriber electronic media distribution system as in claim 1 wherein the receiver is adapted to send a request for the authentication signal to the authentication server.

8. A subscriber electronic media distribution system as in claim 1 further comprising a provisioning system for allowing and restricting display of a sub-group of at least one predetermined one of the broadcast transmissions based upon geographic position of the receiver.

9. A subscriber electronic media distribution system comprising:

a satellite broadcast transmission reception system comprising a satellite signal receiver and a transceiver for transmitting and receiving signals with a provisioning server; and

a satellite broadcast transmission provisioning system for allowing and restricting display of predetermined satellite broadcast transmissions through the satellite signal receiver, the provisioning system comprising a receiver geographic position locating system for determining a geographic position of the receiver,

wherein the satellite broadcast transmission provisioning system is adapted to allow display and restrict display of selected ones of the broadcast transmissions based upon the determined geographic position of the receiver.

10. A subscriber electronic media distribution system as in claim 9 wherein the transceiver comprises a radio frequency transceiver.

11. A subscriber electronic media distribution system as in claim 10 wherein the satellite broadcast transmission reception system further comprises a first satellite signal antenna coupled to the satellite signal receiver and a second radio frequency antenna coupled to the transceiver.

12. A subscriber electronic media distribution system as in claim 9 wherein the receiver geographic position locating system comprises an Assisted Global Positioning System (AGPS).

13. A subscriber electronic media distribution system as in claim 9 wherein the receiver geographic position locating system comprises an Enhanced Observed Time Difference (EOTD) system.

14. A subscriber electronic media distribution system as in claim 9 wherein the transceiver is adapted to send a request for an authentication signal to a server of the provisioning system for displaying a predetermined one of the satellite broadcast transmissions.

15. A subscriber electronic media distribution system comprising:

a broadcast transmission receiver system comprising a receiver;

a geographic locator system for determining a geographic location of the receiver; and

a closed-loop broadcast reception authentication system for allowing display of predetermined broadcast transmissions, received through the receiver system, based upon the geographic location of the receiver determined by the geographic locator system.

16. A subscriber electronic media distribution system as in claim 15 wherein the broadcast transmission receiver system further a satellite signal antenna coupled to the receiver.
