发明名称 Inter-prediction method and video encoding/decoding method using the inter-prediction method
摘要 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.

主权项 1. A video encoding method using inter-prediction, comprising: 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 reference 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; when the first picture is a picture which allows the second picture to refer to the at least one reference picture encoded before the first picture, inter-prediction encoding, after encoding the first picture, the second picture by using a plurality of reference pictures, andencoding reference picture information representing the reference pictures used for encoding the second picture among reference pictures including one or more reference pictures encoded before the first picture, wherein: the one or more reference pictures encoded before the first picture are adaptively deleted from a memory based on whether or not the one or more reference pictures encoded before the first picture are used for encoding the second picture, andwhen the one or more reference pictures encoded before the first picture are used as the reference pictures for encoding the second picture, the one or more reference pictures encoded before the first picture are not deleted from the memory until the second picture is encoded; and when the first picture is not a picture which allows the second picture to refer to the at least one reference picture encoded before the first picture, inter-prediction encoding, after encoding the first picture, the second picture without using the one or more reference pictures encoded before the first picture, wherein the one or more reference pictures encoded before the first picture are deleted from the memory before the first picture is encoded, wherein, the memory includes a reference picture list 0 into which past reference pictures displayed before the second picture to be encoded are inserted and a reference picture list 1 into which future reference pictures displayed after the second picture to be encoded are inserted, andthe reference picture list 0 is allowed to include, in addition to the past reference pictures, one or more future reference pictures which are inserted into the reference picture list 1.
