Abstract:
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 i  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 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.

Claim (Index 1):
An apparatus for decoding comprising:\n a symbol decoder configured to obtain, based on codewords from a data stream, a first sequence of source symbols and a second sequence of source symbols, wherein source symbols of the first and second sequences are related to level values of transform coefficients of a transform coefficient block, wherein the level values of transform coefficients are encoded into the data stream according to a scan order leading through the transform coefficients of the transform coefficient block, and the symbol decoder is configured to obtain a first source symbol of the first sequence using a Rice code and a second source symbol of the first sequence using an Exp-Golomb code; and a composer configured to: compose a sequence of syntax elements having a value range which is sub-divided into a plurality of disjoint portions including at least three portions by, for each syntax element:\n obtaining a set of source symbols from the first and second sequences based on a portion of the plurality of disjoint portions associated with the syntax element, and \n combining values of the source symbols of the set to determine the value of the syntax element; and \n adapt one or more limits between the plurality of disjoint portions according to previously obtained source symbols.
