Abstract
A data transfer system comprises a server and a plurality of devices each operable as a client of the server. The server in turn comprises a notification arrangement to notify a device that it is to become a member of a peer group comprising other clients of the server. The server further comprises a client/server data transmitter to send data to the respective device upon such notification. Each device in turn comprises a client/server data receiver to receive respective data from the server, and a peer-to-peer communicator to send respective data received from the server to one or more peers, and to receive from one or more peers respective data that was sent to it or them by the server.

19. A data transfer system comprising:
-
a server; a plurality of devices each operable as a client of the server and as a peer-to-peer device, and operable to form a peer-to-peer group; the server comprising; a request receiver to receive a request for data from a further device acting as a client device; a notification arrangement to notify the plurality of devices and the further device that they are to form a peer group; and a client/server data transmitter to send data to the further device; the further device comprising; a client/server data receiver to receive data from the server; and a peer-to-peer communicator to receive data from one or more peers in the peer group; and
in whichthe server and one or more peers are arranged to transmit the requested data to the further device in parallel in a complementary fashion until a complete set of data is obtained by the further device, respective proportions of data being received by the further device from the server and the one or more peers being a consequence of their respective data transfer rates.
