Abstract:
An idea used herein is to use the same function for the dependency of the context and the dependency of the symbolization parameter on previously coded/decoded transform coefficients. Using the same function—with varying function parameter—may even be used with respect to different transform block sizes and/or frequency portions of the transform blocks in case of the transform coefficients being spatially arranged in transform blocks. A further variant of this idea is to use the same function for the dependency of a symbolization parameter on previously coded/decoded transform coefficients for different sizes of the current transform coefficient's transform block, different information component types of the current transform coefficient's transform block and/or different frequency portions the current transform coefficient is located within the transform block.

Claim (Index 27):
A non-transitory computer-readable medium for storing information related to a plurality of transform coefficients associated with an encoded video, comprising:\n a data stream stored in the non-transitory computer-readable medium, the data stream comprising encoded information related to first and second symbols of a current transform coefficient, wherein the first and second symbols are processed based on a plurality of operations to reconstruct a block of a picture of the video, the plurality of operations comprising: entropy decoding the first symbol from the data stream using a context, the entropy decoding comprising applying an operation related to at least a first previously decoded transform coefficient to determine the context; mapping the second symbol from the data stream to a transform coefficient level based on a symbolization parameter, the mapping comprising applying the operation related to at least a second previously decoded transform coefficient to determine the symbolization parameter; applying predictive coding based on a prediction residual to reconstruct the block of the picture, wherein the prediction residual signal is associated with the entropy-decoded first symbol and the transform coefficient level; and determining the first previously decoded transform coefficient based on a relative spatial arrangement of the current transform coefficient relative to the plurality of transform coefficients.
