Abstract: A CABAC-type encoding device for encoding an initial flow of binary digital information for generating an output flow for forming video images after decoding, includes: elements for analyzing successive sequences of bits of the initial binary flow, bit-by-bit, and for deducing, for each bit, an interval representing the occurrence probability associated with the bit, the interval being defined by the size thereof and the lower boundary thereof; elements for analyzing the interval and ensuring a renormalization thereof. The elements for ensuring the renormalization include: a reference table containing, for each possible value of the lower boundary and the size, sequences of bits to be inserted into the output flow, and the number of unknown bits waiting to be inserted for this specific renormalization step; and elements for determining the address of the data, in this reference table.
