Abstract

A method is disclosed for creating a bit stream from an indexing tree including a plurality of hierarchical levels, to each of which one or several index nodes are assigned. The index nodes contain index data which is sorted in the indexing tree according to one or several given criteria. Index data of the index nodes is inserted into the bit stream, and the information concerning the position within the bit stream, where the index data of one or several index nodes of the hierarchical level located below the hierarchical level of the respective node is situated, is inserted into the bit stream for an index node.
