- Abstract
- The invention discloses a video decoding apparatus, a video encoding apparatus, and a computer-readable recording medium. The video decoding apparatus includes: a prediction block generation unit thatgenerates a prediction block by performing inter prediction on a current block; and an adder, reconstructing the current block by adding the prediction block and the 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 interprediction of the current block, determining whether to perform scaling on a motion vector of the time reference block; obtaining the time reference block by determining one of the first block and the second block, wherein both the first block and the second block are included in a collocated picture, a position of the first block is determined based on a lower right corner position of the collocated block, a position of the second block is determined based on a center position of the collocated block, and a residual block is obtained by entropy decoding a bit stream.
