ABSTRACT:
An encoding device and method, of CABAC type, for an initial stream of binary digital information intended to generate an outgoing stream to form video images, after decoding, the method included the following steps: bit-by-bit analysis of the successive series of bits of the initial binary stream so as to deduce therefrom, for each bit, an interval representing the probability of occurrence associated with this bit, this interval being defined by its size CIR and its lower bound CIL, analysis of this interval so as to ensure, if necessary, a renormalization thereof. The renormalization is non-iterative and for each bit of the initial stream is compliant with the appended figure in which: M is the length of the sequence S of high-order bits common to CIL and CIR, N is the integer number such that CIR.2N-1<0.25≦CIR.2N, BO is the number of bits waiting to be inserted.
