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.

46. 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. - View Dependent Claims (47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57)

58. An apparatus for controlling access to copyright-protected digital content, comprising a first receiving device 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 (59, 60, 61, 62, 63, 64, 65, 66, 67, 68)
