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 16):
A non-transitory computer-readable medium for storing video data, comprising:\n a data stream stored in the non-transitory computer-readable medium and comprising data associated with a first sequence of source symbols and a second sequence of source symbols, wherein the source symbols of the first and second sequences are related to transform coefficients of a transform coefficient block, and the source symbols are obtained based on 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 executing operations using a processor, the operations including: decomposing each syntax element into a corresponding set of source symbols based on a portion of the plurality of disjoint portions associated with the syntax element, such that a combination of values of the source symbols of the set yields the value of the syntax element, and adapting one or more limits between the plurality of disjoint portions according to one or more previously obtained source symbols, wherein a first source symbol of the first sequence is encoded using a Rice code and a second source symbol of the first sequence is encoded using an Exp-Golomb code.
