GPS TV set top box with regional restrictions
First Claim
1. A video signal access control system comprising a customer access control operable at a customer location and having:
- a signal input to receive at least one video signal from a remote source;
a video signal processor operably connected to receive video signals from the signal input;
a conditional accesser operably connected to the video signal processor;
a signal output operably connected to the video signal processor and providing a useable video output signal only upon the conditional accesser authorizing access to one or more video signals from the remote source;
a GPS signal receiver operable at the customer location to receive position information from remote sources and operably connected to the conditional accesser, the conditional accesser authorizing access only if the GPS signal receiver receives signals consistent with the customer access control being at an authorized location; and
a region comparer to compare a region code received with the at least one video signal from the remote source with a region index stored at the customer location and operable to output a region comparer output, the region code being representative of a geographic region authorized to receive a signal and the region index being representative of a geographic region in which the customer access control is located, there being different region codes for different geographic regions, at least some of the region codes excluding access outside of their corresponding geographic region that is authorized to receive a signal; and
wherein the conditional accesser receives the region comparer output and conditions access to a given one(s) of the video signals from the remote source upon the region comparer output indicating that those given one(s) of the video signals are authorized for an access region in which the customer access control is located, and wherein the region comparer and conditional accesser are together operable to prevent customers at the customer location from accessing video signals having region codes that exclude access in the access region in which the customer access control is located.

Abstract
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 signals. Location-specific signals require that the set-top box be at a single fixed location for descrambling. 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.
