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 21):
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 information related to a transform coefficient block including encoded syntax elements each of which indicates whether a significant transform coefficient is present at a corresponding position within the transform coefficient block, and information related to values of the significant transform coefficients within the transform coefficient block, wherein the syntax elements are encoded into the data stream in a scan order, and in context-based entropy encoding at least one of the syntax elements, a context is selected based at least on a size of the transform coefficient block, a position of the at least one syntax element within the transform coefficient block, and a plane type including a luma plane type and a chroma plane type associated with the transform coefficient block, wherein contexts for different syntax elements are selected based on different combinations of the size of the transform coefficient block, the position of the respective syntax element, and the plane type.
