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 25):
A non-transitory computer-readable medium for storing data associated with a video, comprising:\n a data stream stored in the non-transitory computer-readable medium, the data stream comprising first-type syntax elements and second-type syntax elements both syntax element types related to a transform coefficient block, wherein each of the first-type syntax elements indicates whether at a respective position associated with the first-type syntax element within the transform coefficient block a significant transform coefficient is present, and each of the second-type syntax elements relates to a value of the significant transform coefficient at a respective position associated with the second-type syntax element within the transform coefficient block, wherein the first-type syntax elements are decoded based on context-adaptive entropy decoding using contexts which are selected for each of the first-type syntax elements, wherein the context for a current first-type syntax element being decoded is selected in accordance with a combination of a transform block size and a number of positions of the significant transform coefficients within the transform coefficient block related to previously extracted first-type syntax elements in a neighborhood of the current first-type syntax element.
