Abstract: A decoder for decoding a digital time-varying signal from a data stream is presented. The decoder is configured to decode the digital time-varying signal from the data stream in temporal blocks by decoding each of sample-wise-entropy-coded temporal blocks of the temporal blocks of the digital time-varying signal by sequentially determining a predetermined sample value for sample positions of the respective sample-wise-entropy-coded temporal block by decoding a residual sample value for a current sample position of the respective sample-wise-entropy-coded temporal block from the data stream, and correcting a prediction sample value for the current sample position using the residual sample value. In the decoding the residual sample value for the current sample position of the respective sample-wise-entropy-coded temporal block involves binary context-adaptively entropy decoding a first portion of a binarization of the residual sample value and decoding a remainder portion of the binarization from the data stream, wherein the decoder is configured to derive a context for decoding at least one bin of the first portion using the predetermined sample value of one or more previous sample positions of the respective sample-wise-entropy-coded temporal block.
