1. A method for decoding a sequence of binary elements, the method comprising:
applying, at an input of an artificial neural network, at least one previously decoded value obtained by an entropy decoder that is distinct from the artificial neural network;
producing a context index at an output of said artificial neural network, as a result of the applying the previously decoded values; and
obtaining at least one new decoded value by applying part of the sequence of binary elements to the entropy decoder parameterized in a context identified by the produced context index,
wherein a process of entropy decoding by the entropy decoder is suspended as long as a new context index is not produced at the output of the artificial neural network.
