Patent ID: 8516345

Claim:
A method for the reception of a data stream, via a packet transport network, wherein the method comprises the following steps implemented in a receiver: reception of a data stream; reception of at least one separate error correction stream that is associated with said data stream; reception of a signal of change in state of activation of an error correction by a use of said at least one separate error correction stream, said signal of change being representative of one of at least the following modes: a mode of self-determination by said receiver to use said at least one separate error correction stream, or a mode of forced use of said at least one separate error correction stream by said receiver; a change in state of activation of an error correction by a use of said at least one separate error correction stream according to said signal of change in state of activation, said receiver self-determining said use of said at least one separate error correction stream according to at least one criterion of change in state of activation of an error correction if said signal is representative of said self-determination mode, or said receiver forcibly using said at least one separate error correction stream if said signal is representative of said mode of forced use.
