Method for updating an encoder state register

摘要

A method of updating an encoder (203) state register (203) at a terminal (31) comprises the steps of:
- encoding at least one part (11) of a data stream to an encoded part (12) using an at least one state register (SRE);
- packing the encoded part (12) into a data packet (13) and transmitting said data packet (13) to a network (100) addressed to a destination terminal (32);
- receiving a feedback response (no ACK, NACK) originated by a network element (33; 1001) other than the destination terminal (32), the feedback response (no ACK, NACK) indicating that said network element (33; 1001) was not able to receive said data packet (13) or to forward it towards the destination terminal (32); and
- updating said at least one state register (SRE) responsive to receiving the feedback response (no ACK, NACK).
