Abstract
A video decoding method using inter-prediction, includes: identifying, based on information included in a bitstream, whether a first picture is a picture which allows a second picture preceding the first picture in a display order to refer to at least one picture decoded before the first picture, the first picture serving as a random access picture; decoding the first picture without referring to a reference picture which has already decoded; and when the first picture is a picture which allows the second picture to refer to the at least one picture decoded before the first picture, inter-prediction decoding, after decoding the first picture, the second picture by using at least one reference picture which is decoded before the first picture depending on reference picture information of the second picture.
