1. A non-transitory computer-readable medium for storing data representing a sign-data-hiding enabled block of an image, comprising:
a bitstream stored in the non-transitory computer-readable medium, the bitstream comprising:
a set of context-based adaptive binary arithmetic coding (CABAC) encoded coefficients representing a set of coefficients of a residual block of the sign-data-hiding enabled block, the set of coefficients including a particular non-zero coefficient that is without a sign designation; and
an information item representing a prediction mode of the sign-data-hiding enabled block,
wherein remainder data, which is based on an operation representing a division between a sum of non-zero coefficients in the set of coefficients and a specific number, is used to designate a sign for the particular non-zero coefficient,
wherein the residual block of the sign-data-hiding enabled block corresponds to a difference between an original block and a prediction block generated by using the prediction mode,
and wherein a count of coefficient between a first non-zero coefficient and a last non-zero coefficient in the set of CABAC encoded coefficients is greater than a threshold number.
