The invention concerns methods and devices for transferring data in a network and in particular the transfer of multimedia data. According to the invention described, a point of interconnection receives a configuration map from a client. When the point of interconnection receives a data packet from a server, it analyzes the received packet in order to detect the errors. If the received packet comprises errors and belongs to a stream identified in the configuration map, the point of interconnection selects error correction mechanisms specified in the configuration map. If these mechanisms are capable of correcting all the errors in the packet the latter is transmitted to the client in its original stream. If errors remain, the point of interconnection creates a new packet comprising the data of the received packet, possibly partially corrected, and information relating to the errors detected, to the correction mechanisms used and to the original identity of the data. The packets created by the point of interconnection are transmitted to the client by a particular stream not participating in the constitution of the original multimedia sequence.
