Abstract
A video encoding method using inter-prediction, includes: encoding information indicating 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 encoded before the first picture, wherein the first picture serves as a random access picture; encoding the first picture without referring to a reference picture which has already encoded; and when the first picture is a picture which allows the second picture to refer to the at least one picture encoded before the first picture, inter-prediction encoding, after encoding the first picture, the second picture by using at least one reference picture encoded before the first picture, and encoding reference picture information used for encoding the second picture, wherein the at least one reference picture encoded before the first picture is not deleted from a memory until the second picture are encoded.
