Claim One:
1. A decoder for reconstructing a sample array from an entropy-encoded data stream coded with a video, the decoder comprising: an entropy decoder configured to entropy decode a plurality of slice subsets in the entropy-encoded data stream so as to reconstruct different portions of the sample array, each of the plurality of slice subsets comprising entropy-encoded data for a corresponding portion of the sample array, and the different portions forming rows of blocks of the sample array, each row having a same number of blocks, wherein the entropy decoder is configured to, with respect to each of the plurality of slice subsets: perform entropy decoding along a respective entropy coding path using a first probability estimation, at least by: initializing the first probability estimation before decoding a first block of a first row corresponding to the slice subset based on a second probability estimation of a second block of a second row, the second row spatially-neighboring the first row and corresponding to a preceding slice subset, wherein entropy decoding of the preceding slice subset begins before the entropy decoding of the slice subset and there is at least one block of the sample array between the first block and the second block, and adapting the first probability estimation along the entropy coding path using a previously-decoded part of the slice subset.
