- Abstract
- The invention discloses a video decoding apparatus, a video encoding apparatus, and a computer-readable recording medium. The video decoding apparatus includes: a reference picture buffer storing a reference picture; a prediction block generation unit that generates a prediction block by performing inter prediction on a current block; and an adder reconstructing the current block by adding the prediction block and a residual block, wherein the prediction block 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, determining whether to perform scaling on a motion vector of the time reference block; 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 determinedbased 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.
