Decomposing a value range of the respective syntax elements into a sequence of n partitions with coding the components of z laying within the respective partitions separately with at least one by VCL coding and with at least one by arithmetic coding is used to greatly increase the compression efficiency at a moderate coding overhead since the coding scheme used may be better adapted to the syntax element statistics. Accordingly, in accordance with embodiments, syntax elements are decomposed into a respective number n of source symbols s i with i=1...n, the respective number n of source symbols depending on as to which of a sequence of n partitions (140 1-3 ) into which a value range of the respective syntax elements is sub-divided, a value z of the respective syntax elements falls into, so that a sum of values of the respective number of source symbols s i yields z, and, if n>1, for all i=1...n-1, the value of s i corresponds to a range of the i th partition. |
