Abstract:
1. An entropy encoding apparatus comprising: a subdivider configured to subdivide a sequence of source symbols into a first subsequence of source symbols and a second subsequence of source symbols; a VLC encoder configured to symbol-wisely convert the source symbols of the first subsequence into codewords forming a first bit stream; a PIPE encoder configured to encode the second subsequence of source symbols, represented in form of a sequence of alphabet symbols, the PIPE encoder comprising: a decomposer configured to convert a sequence of syntax elements into the sequence of source symbols by individually decomposing at least a subgroup of the syntax elements into a respective integer number of source symbols such that a mathematical function common for the subgroup, applied upon the integer number of source symbols of the respective syntax element, yields the respective syntax element, wherein the subdivider is configured such that one of the source symbols of the integer number of source symbols of the respective syntax elements belongs to the first subsequence of source symbols and another one of the source symbols of the integer number of source symbols of the respective syntax elements belongs to the second subsequence of source symbols.
