FIELD: physics.
SUBSTANCE: method includes obtaining information on dividing a coding unit; dividing an image into depth coding units using the division information; obtaining a sampling mode indicating which coding unit depth contains a sampling parameter delta; determining the coding unit depth containing a sampling parameter delta; when the depth of the current coding unit corresponds to the determined coding unit depth, obtaining a sampling parameter delta for the current coding unit from said bit stream; performing reverse sampling on conversion units included in the current coding unit using the sampling parameter delta.
EFFECT: higher decoding efficiency.
