1. A method for entropy decoding executed by a video decoding apparatus, the method comprising:
receiving a bitstream that has been generated by encoding a picture;
performing an arithmetic decoding process to generate at least one bin string each including at least one bin by decoding the bitstream; and
generating a syntax element through inverse binarization of the bin string,
wherein the number of bins generated by decoding the bitstream satisfies a constraint that the number does not exceed a threshold;
wherein the threshold is a value calculated based on a size of the picture, a sampling ratio between a luma component and a chroma component, and a bit depth; and
wherein the threshold is variably set according to a tier or level of a video.
