FIELD: video encoding.
SUBSTANCE: adjustment flag is obtained for each of the at least one group of restriction information in the restriction information signalled in the encoded video bit stream. Each control flag indicates whether a group of restriction information from at least one group of restriction information corresponding to the corresponding control flag is present in the restriction information, wherein the restriction information is for a subset of encoding blocks in the encoded video bit stream. It is determined whether the control flag restriction information group is present in the restriction information, wherein the control flag restriction information group includes at least one restriction flag for a subset of encoding blocks. Prediction information for a subset of encoding blocks is determined based on whether a group of control flag constraint information is present in the constraint information. A subset of coding blocks is reconstructed based on the prediction information.
EFFECT: increased efficiency of video coding.
