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 11):
An apparatus for encoding transform coefficient blocks into a data stream, the apparatus is configured to code, into the data stream, a last significant syntax element by entropy decoding, the last significant syntax element associated with a respective position within a corresponding transform coefficient block, indicating information regarding a transform coefficient at the respective position as being the last significant transform coefficient according to a scan order in the corresponding transform coefficient block,\n wherein the apparatus is configured to code the last significant syntax elements into the data stream in the scan order, wherein the apparatus is configured to use, in entropy decoding the last significant syntax element, a context for a current last significant syntax element associated with a current transform coefficient block, wherein the context is selected in accordance with a combination of at least the position of the current last significant syntax element within the current transform coefficient block, information related to at least one corner coordinate of the current transform block, and information regarding significant syntax elements previously extracted from a neighborhood of the position of the current last significant syntax element.
