Abstract
The invention discloses a video decoding device, a video encoding device, and a computer-readable recording medium. The video decoding device includes: a prediction block generation unit that generates a prediction block by performing inter prediction on a current block; and an adder which reconstructs the current block by adding the prediction block and the residual block; wherein the predictionblock generation unit counts a picture order count (POC) value based on a reference picture referenced by the current block and a reference picture referenced by a time reference block for inter prediction of the current block, so that whether to perform scaling on a motion vector of the time reference block is determined; the time reference block is obtained by determining one of a first block and a second block, both the first block and the second block are included in a collocated picture, in which a position of the first block is determined based on a lower right corner position of the collocated block, and in which a position of the second block is determined based on a center position of the collocated block.
