Method and devices for transmitting a data stream according to a multipoint transmission mode

摘要: In a communication network, client has plurality of network interfaces connecting same to server capable generating data streams over multipoint groups. The obtains (301) first request subscribe group making it possible obtain stream. replaces (304) the subscription with second requests sub-groups providing substreams which, once combined, make reconstruct Each is transmitted (306) interface which been associated (305), so as prioritise use each available interface. receives (307), on interface, substream corresponding said and reconstructs (308) stream from substreams.
