Abstract:
The present invention relates to an entropy decoding method which includes: generating context related to a bin that forms a codeword of a syntax element; and performing arithmetic decoding of the bin based on the context.

Claim (Index 21):
An entropy decoding method, by a video decoding apparatus, comprising:\n deriving a split transform flag information for a current coding block; deriving a current luma transform block from the current coding block based on the split transform flag information; deriving context information on a bin constituting a codeword of a syntax element cbf_luma that specifies whether a luma residual other than 0 is present in the current luma transform block; performing an arithmetic decoding on the bin based on the derived context information; and deriving a value of the syntax element cbf_luma based on the decoded bin, wherein the step of deriving the context information includes deriving the context information based on information on a transform depth (trafoDepth) of the current luma transform block, wherein a luma residual other than 0 is not present in the current luma transform block when the derived value of the syntax element cbf_luma is 0, and wherein at least one luma residual other than 0 is present in the current luma transform block when the derived value of the syntax element cbf_luma is 1.
