1. A decoding apparatus comprising:
at least one processor configured to:
obtain first probability information for performing arithmetic decoding for a first bin regarding a first syntax element, based on a first probability model and a second probability model,
obtain the first bin regarding the first syntax element by performing arithmetic decoding based on the obtained first probability information,
obtain a value of the first syntax element corresponding to a first bin string including the first bin,
obtain second probability information for performing arithmetic decoding for a second bin regarding a second syntax element, based on a third probability model and a fourth probability model,
obtain the second bin regarding the second syntax element by performing arithmetic decoding based on the obtained second probability information, and
obtain a value of the second syntax element corresponding to a second bin string including the second bin,
wherein the first probability model is determined based on a first bit-shift value, the second probability model is determined based on a second bit-shift value, and the second bit-shift value is determined to be greater than the first bit-shift value, and
wherein the third probability model is determined based on a third bit-shift value, the fourth probability model is determined based on a fourth bit-shift value, and the fourth bit-shift value is determined to be greater than the third bit-shift value.
