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 4):
The decoder according to  claim 2 , wherein the context adaptive entropy decoder is configured to entropy decode the first symbol for the last non-zero transform coefficient using a context that is different from a context used in entropy decoding the first symbol of a transform coefficient other than the last non-zero transform coefficient.
