Abstract:
1. A method of peer to peer transfer of content, said method comprising the steps of: transmitting, from a first device, a first request with a first selection criterion for a first content to a server or to a second device in a peer to peer network; in said server, in response to receiving said first request, when said server previously has acknowledged said first device as a legal recipient of said first content: checking if the first content satisfying said first selection criterion is available in said peer to peer network only on said server; if so, transferring the first content to said first device, and noting that said first device subsequently has the requested first content available for other devices; and otherwise re-directing said first request to a third device on which the server knows that the requested first content is still available; in said third device, in response to receiving said re-directed first request, transferring said first content satisfying said first selection criterion to said first device; in said second device, in response to receiving said first request, checking if the first content satisfying said first selection criterion is available on said second device and has been supplied by said server to said second device or has been approved by said server for subsequent transfer by said second device; if so, transferring the first content satisfying said first selection criterion to said first device, and informing the server that said first content has been transferred to said first device from said second device; and rewarding the one of said second or third device from which said first content was transferred to said first device, when content was transferred from one of these; and charging said first device for reception of said first content.
