Abstract

An image decoding method performed by a decoding apparatus according to the present document comprises the steps of: obtaining a sign data hiding availability flag indicating whether or not sign data hiding is available for a current slice; obtaining a TSRC availability flag indicating whether or not TSRC is available for a transform skip block of the current slice; obtaining residual coding information about the transform skip block on the basis of the TSRC availability flag; deriving a residual sample for the transform skip block on the basis of the residual coding information; and generating a reconstruction picture on the basis of the residual sample, wherein the TSRC availability flag is obtained on the basis of the sign data hiding availability flag.
