摘要： An integrated receiver decoder (IRD), commonly called a set-top box, has a global positioning system (GPS) receiver. The GPS receiver checks to see if the IRD is at an authorized location and allows descrambling of video signals only if the location is authorized. A central access control system, remote from the customers/viewers, has a high quality GPS receiver and sends some GPS data in the transmission medium used to send video signals to the customers. The set-top box, referred to as a customer access control, establishes different geographic restrictions on different of various video or data signals. Location-specific signals require that the set-top box be at a single fixed location for descrambling. Geographic filtering of data signals is provided. Region-specific signals are accessible only if the set-top box is in a geographic region authorized for reception, there being several such regions. Large area signals are accessible anywhere within a large area including the regions. Region-exclusion signals are accessible only if the set-top box is outside of one or more regions where reception is no allowed.

摘要： An integrated receiver decoder (IRD), commonly called a set-top box, has a global positioning system (GPS) receiver. The GPS receiver checks to see if the IRD is at an authorized location and allows descrambling of video signals only if the location is authorized. A central access control system, remote from the customers/viewers, has a high quality GPS receiver and sends some GPS data in the transmission medium used to send video signals to the customers. This GPS data, referred to herein as indirect GPS data, is used by the IRD such that it requires less complexity than otherwise. The IRD introduces a pseudo-random time delay in generating certain signals such that spoofing (i.e., providing phony signals to the IRD) is much more difficult. Various components of the IRD are in a common sealed container such as an integrated circuit or a smart card such that tampering with the components and spoofing are more difficult.

摘要： The footprint of a first satellite is reconfigurable in orbit by ground control to switch on and off different transponders. Each transponder is connected to a corresponding downlink antenna feed, each of which transmits a downlink beam independent of the others. The satellite can be moved into different orbits or otherwise changed to service new geographic areas by using different combinations of the transponders. In one embodiment, the satellite includes an antenna and components for an uplink beam corresponding to each downlink beam. Various subsets of the downlink antenna feeds are mechanically linked to move in unison using gimbals, each subset using a corresponding gimbal and mechanical driver. The first satellite is sufficiently reconfigurable that it may serve as a back up satellite to a plurality of other satellites in a constellation of satellites.
