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.

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.
摘要翻译：通常称为机顶盒的集成接收机解码器（IRD）具有全球定位系统（GPS）接收机。 GPS接收机检查IRD是否在授权的位置，并且只有在该位置被授权时才允许对视频信号进行解扰。远离客户/观众的中央门禁系统具有高质量的GPS接收器，并在用于向客户发送视频信号的传输介质中发送一些GPS数据。这里称为间接GPS数据的GPS数据由IRD使用，使得其需要比其它方式更少的复杂性。 IRD在产生某些信号时引入伪随机时间延迟，使得欺骗（即向IRD提供虚假信号）要困难得多。 IRD的各种部件在诸如集成电路或智能卡的公共密封容器中，使得篡改部件和欺骗更加困难。
