Abstract

An apparatus for decoding a data structure from a data stream is configured for sequentially reconstructing a set of features, wherein the apparatus is configured for reconstructing a feature of the set of features by deriving a quantization index from the data stream using arithmetic decoding; mapping the quantization index to a reconstruction value in dependence on a quantization state, and assigning the reconstruction value to the feature; updating the quantization state in dependence on the quantization index and the quantization state; and deriving the data structure based on the set of features. The apparatus is configured for deriving probabilities for the arithmetic decoding of the quantization index in dependence on the quantization state.
