摘要

inter prediction method, inter prediction apparatus, video decoding apparatus, video encoding apparatus, and computer readable recording means an inter prediction method including determining a collocated block of a current block of a current image within blocks of an image which is restored before the current image; preferably checking whether a first reference list within the collocated block reference lists is referenced and selectively checking whether a second reference list is referenced according to whether the first reference list is referenced; based on a scan result, determine a single reference list placed between the first reference list and the second reference list; determining a reference block from the current block using motion information from the placed reference list; and perform inter prediction on the current block using the given reference block.
