1. A method for determining whether a second receiving device is authorized for access to copyright-protected digital content received from a first receiving device, the method comprising:
- receiving electronic copyright protected content at a first receiving device authorized for electronically redistributing the protected content within a subscriber domain of receiving devices comprising the first receiving device and the second receiving device, subject to content usage rules that specify a defined maximum separation distance from the first receiving device for receiving devices in the subscriber domain;
receiving a request from a second receiving device, requesting that access to the protected content received by the first receiving device be provided to the second receiving device;
determining a geographic separation distance between the first receiving device and the second receiving device, in response to receiving the request;
providing the second receiving device with access to the protected content if the determined separation distance does not exceed the defined maximum separation distance specified by the content usage rules; and
preventing the second receiving device from accessing the protected content, if the determined separation distance exceeds the defined maximum separation distance.

Abstract
A method and system for controlling distribution of content within a personal domain that makes use of a determination of the relative proximity to a source device or the geographic locations of the receiving devices. The location information may be determined using a Global Positioning System (GPS) or wireless triangulation systems. Usage rights for devices in the network are determined using the location or proximity determination.

13. An apparatus for controlling access to copyright-protected digital content, comprising a first receiving device including at least one processor operatively coupled to a computer memory, configured for:
-
receiving copyright protected content subject from a remote source; electronically redistributing the protected content within a subscriber domain of receiving devices defined by proximity to the first receiving device, subject to content usage rules that specify a maximum separation distance relative to the first receiving device for authorized devices in the subscriber domain; receiving a request from a second receiving device, requesting that access to the protected content received by the first receiving device be provided to the second receiving device; determining a geographic separation distance between the first receiving device and the second receiving device, in response to receiving the request; providing the second receiving device with access to the protected content if the separation distance does not exceed a defined maximum separation distance specified by content usage rules for the protected content; and preventing the second receiving device from accessing the protected content, if the separation distance exceeds the defined maximum separation distance. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
