1. A method for encapsulating a plurality of substreams of data coded in a binary train, a substream of coded data being obtained by entropy coding of a sub-sequence of symbols which is representative of an image or of a series of images, said method comprising:

  • grouping the substreams of data into pairs of substreams according to an order of predetermined iterative scanning of said plurality of substreams;

    on the basis of a pair, obtaining a symmetric pair by reversal of an order of the data making up the second substream of the pair;

    concatenation of the pairs obtained into a sequence; and

    creating the binary train by encapsulating said sequence and information items relating to a number of substreams and to sizes of the pairs of symmetric substreams.
