In a method in compression coding of digitalized image or video information, especially for effective bit representation of parameters for side information in the forms of classification tables or motion vectors, wherein the parameter to be coded is represented by a vector with integer components, the vector is enumerated hierarchically in two or more levels by partitioning the vector in subvectors and/or vector elements on each level, binary code words are generated for each subvector and/or each vector element on a given level, said binary code word for a subvector and/or a vector element on one level being formed by the binary code words for the subvectors and/or the vector elements on a lower level, and a binary code word with fixed length for the vector is generated from the binary code words for the subvector or the vector elements of the immediately underlying level of the hierarchy. |
