The value range of each syntax element is decomposed into n partitioning sequences, and the z components in each partition are individually coded at least one by VCL coding, and coding at least one by PIPE or entropy coding is an intermediate coding over. It is used to significantly increase the compression efficiency in the head, since the coding scheme used can be better adapted to the syntax element statistics. Therefore, according to an embodiment, the syntax element is decomposed into each number (n) of source symbols, and the source symbol of each number (n) is in any of the sequence of
n divisions (140 1-3), The value range of each syntax element is subdivided, and depending on whether the value (z) of each syntax element belongs,
the sum of the values of the source symbols (s i ) of each number is calculated as z, and n>1 In the case, for all i=1...n-1,
the value of s i corresponds to the range of the i-th division.
