Abstract
A place-shifting system for distributing video content from a content source (2) has apparatus including a set-top box (STB) (1) with a digital interface to a sender (6). The sender (6) receives video content from the STB (1) conditional upon access permissions that may be associated with a subscription. The permissions may also be determined using the identifier of a viewer device (9). The viewer (9) requests connection to a specific sender (6) by sending an association request to an association server (8) via a network connection (10). The association server (8) returns location information specific to the sender (6) being requested to the viewer (9). The viewer (9) and sender (6) then communicate directly (11) to establish communication and to start transfer of video and other information. The sender (6) can remove content protection from the video content before transcoding, re-applying content protection and sending it. The viewer (9) can act as a remote control for the STB (1) and modifies of the format of On-Screen Display data depending on its video output capability.
