A method of low latency encoding of an input bit sequence (S0) to yield an encoded bit sequence (S), and a corresponding decoding method, said encoding method including: a first encoding step (E1) applied to bits of the input bit sequence (S0), using a first code; an interleaving step (E3) in which an interleaver interleaves the bits obtained from said first code; and a parity, second encoding step (E4) applied to the bits obtained from said interleaver, using a second code, to generate said encoded bit sequence (S). The parity, second encoding step (E4) starts after a predetermined number Δ of bits have been interleaved, said predetermined number Δ of bits ranging between a first lower number Δi of bits depending on one or more parameters of said interleaving step (E3) and a first higher number Δs of bits corresponding to the total number of bits to be processed during said interleaving step (E3).
