Abstract
A television set top box (STB) or similar receiver device uses information obtained from a wireless interface to automatically detect when the device has been moved to a different location. The device may initially obtain a list of wi-fi zones or in-range wireless devices that can be quantified or stored for later comparison. If the device later finds that the original zones/devices are no longer present or that substantial numbers of new zones/devices are present, then the device can recognize that it has been moved to a new location. The device may respond to the detected location change by disabling premium content, by reporting back to a security service, by simply recording the change in location, or by taking other actions as appropriate.
