Abstract:
A higher coding efficiency for coding a significance map indicating positions of significant transform coefficients within a transform coefficient block is achieved by the scan order by which the sequentially extracted syntax elements indicating, for associated positions within the transform coefficient block, as to whether at the respective position a significant or insignificant transform coefficient is situated, are sequentially associated to the positions of the transform coefficient block, among the positions of the transform coefficient block depends on the positions of the significant transform coefficients indicated by previously associated syntax elements. Alternatively, the first-type elements may be context-adaptively entropy decoded using contexts which are individually selected for each of the syntax elements dependent on a number of significant transform coefficients in a neighborhood of the respective syntax element, indicated as being significant by any of the preceding syntax elements.

Claim (Index 16):
A non-transitory computer-readable medium for storing data associated with a transform coefficient block, comprising:\n a data stream stored in the non-transitory computer-readable medium, the data stream comprising an encoded significance map indicating positions of significant transform coefficients within a transform coefficient block, and the significant transform coefficients within the transform coefficient block, wherein the significant transform coefficients are encoded into the data stream by context-adaptive entropy encoding such that each of a plurality of sub-blocks of the transform coefficient block is entropy coded using one or more contexts determined for that sub-block separately from the other of the plurality of sub-blocks, each of the plurality of sub-blocks including information about a plurality of pixels, and transform coefficients within each of the plurality of sub-blocks of the transform coefficient block are scanned in a position sub-scan order, wherein the significant transform coefficients of a sub-block of the plurality of sub-blocks are context-adapted entropy encoded using a selected set of contexts from a plurality of sets of contexts, the selected set of contexts being determined based on a specific value related to one or more of the significant transform coefficients of a previously traversed sub-block of the transform coefficient block.
