Claim Text:
1. A video decoding method comprising: parsing, from a bitstream, offset merge information indicating whether an offset parameter of a current block is determined according to an offset parameter of a neighboring block; when the offset merge information indicates that the offset parameter of the current block is determined according to the offset parameter of the neighboring block, determining the offset parameter of the current block using the offset parameter of the neighboring block; and when the offset merge information indicates that the offset parameter of the current block is not determined according to the offset parameter of the neighboring block, obtaining, from the bitstream, the offset parameter of the current block, wherein, the obtaining the offset parameter of the current block from the bitstream comprises: wherein the plurality of offsets corresponds to a plurality of bands, wherein an absolute value of an offset to be applied to a current sample of the current block is determined among the absolute values of the plurality of offsets, according to which band the current sample is included among the plurality of bands, and wherein a sign bit of an offset to be applied to the current sample is determined among the sign bits of the plurality of offsets, according to which band a current sample of the current block is included among the plurality of bands.
