Abstract
Apparatuses decode or encode a picture sequence, some having different resolutions, and transmit a bitstream of video data. The decoding apparatus has at least one processor, which decodes a first syntax element for specifying a reference size of pictures referring to a high-level syntax structure and a second syntax element for specifying a picture size scaled from the reference size. The processor also derives, based on the first and the second syntax elements, at least one offset factor and at least one scale factor representing a scale difference between a current picture including a current block to be decoded and a reference picture referred to by the current block. The processor generates a prediction block of the current block from the reference picture by using the motion vector of the current block, the at least one scale factor, and the at least one offset factor.
