简介
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 VLC coding and with at least one by PIPE or entropy 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, syntax elements are decomposed into a respective number n of source symbols s, with i= 1... n, the respective number n of source symbols depending on as to which of a sequence of n partitions 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, yields Z. and, if n> 1, for all i= 1... n-1, the value of s, corresponds to a range of the i'partition.
