Web3) binary arithmetic coding In the first step, a given non-binary valued syntax element is uniquely mapped to a binary sequence, a so-called bin string. When a binary valued syntax element is given, this initial step is bypassed, as shown in Fig. 1. For each element of the bin string or for each binary valued syntax element, WebBinarization: CABAC uses Binary Arithmetic Coding which means that only binary decisions (1 or 0) are encoded.
